I've created some Web API methods in .NET 4 / Visual Studio 2010 (and have now ported it to VS 2013 RC).
I want to consume them from a Windows CE / Compact Framework app using RestSharp.
Regardless of how I call these methods, though, I need to know the IP Address to use for the app running the Web API methods. I can access it from a browser using "localhost" and the port number Visual Studio displays when running the View for the Web API project in the browser (works fine, returns XML in Chrome).
But: how can I call it from my Windows CE / Compact Framework app? The emulator in which I run it doesn't believe that it and localhost are really on the same machine, so I can't use that, nor the machine's actual IP address as, again, it is delusional about who/where it is.
So: what is the workaround? How can I test this?
More details about this can be seen here: RFC on HttpWebRequest vs RESTSharp from Windows CE / Compact Framework 3.5
UPDATE
Vasily, my guess was that you meant for me to do this:
...but that led to this:
Note: I get the same when I choose the other option from the dropdown asociated with the "Enable NE2000 PCMCIA network adapter and bind to:" czechbox, namely "Intel(R) 82579LM Gigabit Network Connection".
And trying to install http://go.microsoft.com/fwlink/?linkid=46859 (both the 64-bit and the 32-bit flavors) slapped me with:
So tell me, I implore: Is there balm in Gilead, so that there may be joy in Mudville tonight?
UPDATE 2
In step 6 (bullet 6), I did this:
...which got me first a message that the software didn't install correctly, with the option to retry or assert that, no, everything is really fine (I chose the latter), but then this:
...IOW, I don't make it to step/bullet point 7
Then again, this Peek cat did warn, "Note that this is very much a “works on my machine” experience. If it burns your house down, don’t hold me responsible."
My house didn't burn down (I don't think - I'm not there right now), but the process to extract the file did fail ignominiously.
You can use workstation network card by the emulator. Todo it you have to select "Use installed network card" checkbox and select the card from the list. after that you can use the workstation ip.

Windows Virtual PC and the Microsoft Device Emulator
I've had to use it more than a couple of times.
I saved the file as a PDF to my network folder, so it took me a while to find the link.
Overview:
Chromedriver works normally on one machine but extremely slowly on two other identical machines.
Setup:
Selenium Webdriver using .Net for coding and Selenium Grid for distributing the tests. MSTest is being used from within Visual Studio 2010 in order to run the tests.
A 64bit Windows 7 local machine acting as the Hub
Three 32-bit Win 7 remote machines (two of them are virtual) on my local network all configured as nodes. Here is the command used to start the nodes on the remote machines:
java -jar c:\seleniumWebDriver\seleniumGrid\selenium-server-standalone-2.31.0.jar -role node -hub http://XXX.XXX.XXX.XXX:4444/grid/register -browser "browserName=chrome",maxInstances=4 -Dwebdriver.chrome.driver="C:\seleniumWebDriver\chromedriver.exe"
The driver is launched like this from within the code:
DesiredCapabilities capability = new DesiredCapabilities();
capability.SetCapability(CapabilityType.BrowserName, browser);
driver = new RemoteWebDriver(new Uri(hubUrl), capability);
The variable "browser" and "hubUrl" above is passed via an app.config file that is built at runtime. For this case, browser=chrome.
Problem:
When I setup machine 212 (which is a virtual machine) as a chrome node using the command above, and then launch the scripts from the hub, I see chrome start in the proper remote machine and run normally. It fields between 5-10 commands per second.
When I setup either machine 78 (virtual machine) or machine 103 (real machine) as a node in the same manner, and then launch the scripts from the hub, I see the node start up chrome properly. However, it runs extremely slowly, like 1 command per sec or less.
Other info:
Like I said, on one machine chrome works normally, but on the others, runs extremely slowly. Firefox and IE, when configured as nodes, work normally.
I have compared the machine 212 (which works properly) with the other machines and cannot find the difference. All the machines are using 'selenium-server-standalone-2.31.0.jar' and the same version of the ChromeDriver.
It does not appear that the node machines are being overloaded. Also, it is a very consistent difference in performance which does not seem related to any fluctuating load on the network or the machines.
My network tech has verified that all these machines are configured identically on the network.
Has anybody seen anything like this before?
EDIT 1: I logged in today and all three remote machines are running chrome slowly. Before one of them was normal, but now they are all slow.
I ran into a similar issue where chromedriver was slow in some machines and it turned out to be a proxy issue. Disabling "Automatically detect settings" under Chrome://settings >Change proxy settings> LAN Settings> made webdriver execute commands faster in chrome for me.
My proxy settings were not using automatic detection, but I found the following helped a lot. The time it took to start the driver went down from 43 seconds to 1 second
driver = new ChromeDriver(new ChromeOptions{Proxy = null});
Bug link in chromedriver issues This is long lasting issue that got lowest priority. But as more user will vote for it maybe someone will fix it. It could also be releated to Parsing of proxy configuration is not standard compliant which will be fixed soon.
This code solved the problem for me for Chrome 75 on macOS 10.14.3
ChromeOptions options = new ChromeOptions();
options.setProxy(null);
driver = new ChromeDriver(options);
I'm trying to setup automated GUI tests in ESXi Virtual Machines using TestComplete. The problem, as I understand it, is that when no remote desktop connection is made to the ESXi virtual machine, then it is impossible for TestComplete to perform screen captures and therefore automate the GUI testing. As far as I understand it, this is due to the fact that Windows does not generate any user interface when nobody is viewing it.
I'm sure other have experienced this problem. How did you solve it ? Are you using a third party computer which automatically launch remote desktop connections prior to running the tests ?
Would it be possible to launch a remote desktop from a head-less virtual machine to another to fake somebody viewing ?
Any other smarter solutions I haven't thought about ?
You should be able to log in to Windows on the VM's console using the vSphere client, then close vSphere, and Windows will still believe the user is viewing the console. Simple as that. :)
So there shouldn't be a need to involve remote desktop in the mix.
As long as your tests then run as that logged-in Windows user, you should be fine.
This technique has always worked like a charm for me with certain Watir, Selenium, and MS UI Automation tests that depend on having an interactive desktop.
If you need to reboot the VM automatically before/during the test, instead of logging in manually in the vSphere client, you can make Windows log in as an arbitrary user automatically - check the "control userpasswords2" command, or you can use the Sysinternals app "Autologin":
http://technet.microsoft.com/en-us/sysinternals/bb963905
Only catch with this technique is that you need to be able to launch your tests while not viewing the console on the VM, but it sounds like you've already taken care of that?
If you need a solution for launching your tests remotely, I highly recommend using Jenkins or Hudson to kick off tests/collect results from the VM. Jenkins has changed my life in this regard.
You may consider using the Network Suites functionality of TestComplete:
http://smartbear.com/support/viewarticle/16849/
It can open Remote Desktop connections on its own, control tests on remote PCs, and pull the logs back to the "master" project. This feature is designed to be used for distributed tests, and looks like it's just what you need.
As for opening RDP to a head-less VM, it should not be a problem - it's up to Windows to "think" about this. You just open RDP and it works even if there is no monitor attached to the remote PC/VM.
I hope this helps,
Alex
You can always use VNC with checking the option "Do nothing" when disconnecting viewer. This way you'll trick windows to generate the image.
I'm currently working in web development and my default desktop is Ubuntu and I'm kind of happy with the setup and applications I got going. But I need to test web pages for cross browser compatibility while still being on Ubuntu.
I have gone through hell trying to get IE7 or IE8 (with wine) to run on ubuntu and when they finally worked they were very buggy and the graphics/scrolling was insanely slow.
Of course there is the option of virtual box but again, too much GBytes just to run a small application!
So to all the CSS gurus out there, how can I continue with my beloved Ubuntu and still deliver a good quality (tested) page.
Thank you.
Edit:
Update for freshness:
I now use the paid service from browserstack.com to provide the multitude of different browser testing environments via flash tunnelling. I'm a paid user, but there is an initial free trial period. browserstack has freed me of the need to run the windows os on my machines in any form, virtual image or otherwise. Since it also allows tunnelling, I can host the site on my local machine but still test in browserstack browsers. I consider the monthly fee money very well spent.
End Edit
Various options I have tried, including "the final solution": free downloadable windows testing OSes from microsoft
I've tried a number of the options below, but virtualbox may be your best bet for full & complete testing, especially because in a professional capacity you often have to test ie8, ie7 -and- ie6. Which gets tricky with only a single os installed. So in order of simplest and most shallowly testing to most complex and most fully testing:
browserlab.adobe.com
A newer, interesting online solution is: browserlab.adobe.com. It's actually very specific and fast compared to browsershots. It only gives you screenshots, but it's a great first step. So I do recommend that for purely visual (and thus relatively shallow) testing.
Browsershots.org
And while browsershots.org is also something that you should use for an overview experience of what users might see, you really can't get by without the real browsers for javascript and behavior testing (instead of just display & rendering testing that browsershots provides). The delay before you can see the images is also killer.
Dual booting into windows
Another that I've tried is dual booting, I work 99% of my time in ubuntu, and I have windows installed & available to dual boot into. Not a fast way to test, but if you don't have any other way to access ie, it should work for at least the latest version.
Remote desktop-ing over to a running windows box
Before I mention the "covers-all-the-bases" option, another useful possibility is to set up a windows machine and boot it up and connect to it via remote desktop so that you can work from one machine and test from both.
The final solution, using virtualbox
Finally, the mother of all solutions, using virtualbox:
Luckily (I know you said you didn't like the virtualbox solution, and I know it's an annoying setup process, but...) Microsoft provides available-for-a-year-or-more virtualmachine distros with different versions of ie pre-installed, available without the need for a license for a year or so before you'd have to update the virtualmachine, #

Installing a virtualmachine from microsoft's freely available browser testing images
Because this guide to setup on ubuntu is no longer available in full anywhere else, just in case you or someone else actually need it I feel compelled to include the actual details of the install process that were suggested to me on the ubuntu forums and worked when I went through them. I apologize for their length. Courtesy of the now anonymous original poster on the ubuntu forums:

HOWTO: run IE6, IE7, IE8 on Linux in
VirtualBox You need: virtualbox, qemu,
wine
Code: apt-get install virtualbox qemu
wine
Download the free(!) Microsoft
Internet Explorer Application
Compatibility Check VPC Images here:
http://www.microsoft.com/downloads/details.aspx?FamilyId=21EABB90-958F-4B64-B5F1-73D0A413C8EF&displaylang=en
(Note: you don't have to download the
full pack, you can cherry pick
specific combinations of XP/Vista and
IE6-8)
Extract the VPC image(s) with wine
(double-click). (Note: it might take a
while before the first window shows
up)
Turn the VPC image(s) into (a) VMWare
image(s) (which is/are readable by
VirtualBox): qemu-img convert -f vpc
image.vhd -O vmdk image.vmdk
Setup a new VM in VirtualBox, using
the vmdk image as an existing disk.
Boot it, you will see the Windows boot
progress bar and ... it will BSOD
shortly after.
Fixing the BSOD:
The BSOD is caused because the virtual
Windows tries to load processor
drivers for the wrong processor (it is
not running on VirtualPC proc, but on
VirtualBox proc). Or something like
that... We need to force Windows not
to attempt to load drivers for the
processor (it doesn't need any proc
drivers, because it's all virtual
anyway). Start safe mode by
(frantically) hitting F8 at Windows
boot and choosing safe mode.
Ignore all the 'New hardware' detected
warnings (we will deal with those
later). Start a command box and run
the following command to disable the
loading of processor drivers:
Code: sc config processor start=
disabled (note the space between '='
and 'disabled'!)
Restart the virtual Windows, it should
now boot all the way to the Windows
Desktop.
Now just when you think you can start
browsing the web with IE, you will
find out that the virtual Windows
needs to install the drivers for the
AMD PCnet NIC, which are located on
the Windows install disk. Fortunately
for those without a Windows install
disk, there is another way :)
Download AMD PCnet drivers here:
http://www.amd.com/us-en/ConnectivitySolutions/ProductInformation/0,,50_2330_6629_2452%5E2454%5E2486,00.html
Make an iso file containing the
drivers. I used Brasero for
simplicity. Choose to create a Data
Project, add the zip file (or the
unzipped files, saves you a step in
Windows), create the iso. No need to
burn an actual cd!
Stop the virtual Windows, edit the
settings in VirtualBox: mount your
brand new iso.
Start the virtual Windows, when it
asks to install the drivers for the
PCnet nick, point it to the (unzipped)
drivers. Et voila! You have teh
innernets! (Now you can also try to
install the other drivers it complains
for, but it's not really necessary)
The image README says the image will expire after about a year. In my experience the system gets hobbled against multi-hour use, but is still usable for the kind of short periods that you might want when booting up to test a website. At worst you might have to go through these steps again, so be sure to put them somewhere where you can find them again after a year or so.
I think setting up a virtual machine (Virtualbox or VMWare or...) with a proper Windows will be your only (local) option.
I you don't have one, buy a used Windows XP license. XP is cheap (around 20-30 euros here in Germany, for example) and all relevant versions of IE run on it. Home edition is enough. No need for Windows 7 or anything.
You could install IETester on that to get all the IE versions on one OS. IETester has flaws and is not always 100% reliable in what it renders, but for a general CSS compatibility check it should be okay.
I've never tried IE using Wine, but even trying to imagine the combination gives me goose bumps :D
If you have a copy of Windows you could install it in a virtual machine (Virtualbox is a good, free option). Or if you don't mind a lot of lag time and publicly exposing your web pages you could use a service like BrowserShots.
I have not tried this on Ubuntu or anything but windows - but this seems to be a pretty good testing system over the web.
http://spoon.net/browsers/
however, I think your best result would be to use a VM if possible.
I have to add my voice to those opting for VirtualBox.
VMs are the only way to get an accurate representation of how IE platforms behave. They also allow you to keep your main Linux install free of WINE and IE gunk, which is otherwise always troublesome and fragile. (Especially if you're trying to run multiple IEs, which is unreliable and inaccurate even under Windows).
They're not necessarily that big, if you take care to prune the unneeded features, turn off swap, compact the disc image and so on. My XPSP3 test image is just over 800MB.
I didn't want to install all this stuff as I wanted to move forward quick.
I found public AWS images with pre installed browser that you just can start and use.
http://www.hens-teeth.net/html/products/cross_browser_testing.php
If you already have an AWS account this will take you only 5 min. Make sure that you enable the RDP port on the incoming traffic in your security group.
As I use ubuntu I was looking for a way to connect from it to MS Win.
I'm connection on to them via remote desktop.
The way to go here is rdesktop, a command line utility for Windows Remote Desktop. (sudo apt-get install rdesktop)
If you feel like a GUI use tsclient. It's very close to the windows version.
From a work flow perspective I develop for Chrome in Ubuntu first, then have a look at the other browsers via browserlab.adobe.com.
After that I start my new AWS instance to debug.
The small AWS Windows instance is a $0.12 per hour (http://aws.amazon.com/ec2/#pricing). I can work for a long time on that before it's worth installing all this stuff.
CrossBrowserTesting.com works from Linux. Allows you to access Mac, Windows, and Ubuntu configurations and all the browsers loaded on them via vinagre vnc client.
When I try to connect to local ports, Computer -> Connect local, using Portmon v. 3.02, I'm getting an error message, Error 2, in a small error dialog box:
I run the tool as an administrator (if not, I get error 6).
By the way this is a Windows 7 x64. On 32-bit, in Windows 7 x86, it works fine. How can I fix this problem?
Sysinternals' Portmon works only on 32-bit versions of Windows. It does not support 64-bit (probably its driver is not signed).
From the Portmon homepage:
Runs on:
Client: Windows XP (32-bit) and higher (32-bit).
Server: Windows Server 2003 (32-bit) and higher (32-bit).
In Windows Explorer, right click on portmon.exe --> select Properties --> click the Compatibility tab, and Run in Windows XP compatibility mode. It works fine like that in Windows 7 64-bit.
"Error 2" is "Cannot find the file specified", that is, cannot find a required DLL file.
Originally, you got this error when you tried to run Portmon from a network location: that broke the security trust, causing Portmon to be untrusted (or perhaps just messing up the search path somehow).
On my copy of Windows 7 64 bit, Microsoft Dependency Walker (depends.exe) tells me that PORTMSYS.SYS (the file created/loaded by Portmon.exe), has unresolved dependencies on ci.dll, clfs.sys, hal.dll and kdcom.dll.
Those are the
code integrity
common log file system
hardware abstraction layer
kernel debugger com
libraries, and they aren't actually missing: if they were, Windows wouldn't boot. However, I don't see a copy of those files in SysWow64. This suggests to me that the problem is not with portman.sys: the problem is with the win32 compatibility layer in Windows 7/64 bit: It doesn't support debug properly.
It is now 2018. There is no 64-bit version of Portmon. Serial ports are a legacy standard. The Windows 7 problem was fixed by the release of Windows 8.1. However, there is a faint chance that some Visual Studio utility or security update back-ported to Windows 7 will fix the problem. Perhaps someone who is familiar with SysWow and debugging will comment.
Instead of portmon for Windows x64, you can use an emulator of a pair of virtual COM ports and a simple program that will connect the physical port and one of the virtual ones, as well as perform the logging function.
To create a pair of virtual COM ports you can use:
com0com (preferably version "com0com-2.2.2.0-x64-fre-signed", because it contains signed x64 driver)
Virtual Serial Ports Emulator (VSPE), every time it starts on x64 it asks to purchase a driver, but it works even if you refuse.
Simple mapping and logging program can be found e.g. here or you can write it yourself, it is simple.
The sequence of actions is follows:
Сreate a pair of virtual COM ports using emulator (for example, COM28 and COM29)
Let the external device be connected to the computer COM1 port. In the program, whose exchange with external device we want to listen to, we set up a port COM28 (instead of СОМ1) for communication.
In the mapping program, we set up that we want to bind and log ports COM1 and COM29 (don't forget to set the port baud rate).
I haven't tried it yet, but this question mentions com0com. It creates two virtual serial ports and emulates a null modem cable between them. It claims to be able to run on 64 bit Windows. I'm not sure whether it comes with software that lets you just pipe input from a real port into one of the virtual ports. One of the FAQ's says that you can turn on logging.
I guess in the worst case, you could write your own small program that pipes data from a real port to one of the virtual ports and logs it all.
There's also this question on open-source alternatives that mentions a couple of projects.
I've used AccessPort
http://sudt.com/en/ap/download.htm and it works great. Very similar to Portmon
Don't start Portmon from a network drive/path or something else.
Copy on to the hard disk drive, e.g. on the desktop, restart and try again!
If you run Portmon in compatibility mode, it will work.
Check Make older programs run in this version of Windows.
It says:
To run the Program Compatibility troubleshooter:
Open the Program Compatibility troubleshooter by clicking the Start button Picture of the Start button, and then clicking Control Panel. In the search box, type troubleshooter, and then click Troubleshooting. Under Programs, click Run programs made for previous versions of Windows.
Follow the instructions in the troubleshooter.
The above is a public explanation from Microsoft for a common situation when running older applications in Windows.
But, I can say it briefly;
Right click on portmon.exe
Select menu about "troubleshooting compatibility problem" or something like that (I'm using a foreign version of Windows, so I don't see correct name of that menu in English.)
Select automatic mode
It will detect the problem and recommend Windows XP (SP2) mode
Select it and execute Portmon again.
I hope it works!
Instead of Portmon you can also use the IO Ninja program with the "Serial Monitor" plugin.
It gives a little less information than Portmon, but in a more understandable form. The main thing is, just like a Portmon, it allows you to see the data that is transmitted between a third-party application and an external device via a serial port. The program works under modern versions of Windows (I tried it myself on Windows 10 x64). The aforementioned plugin "Serial Monitor" is paid (but has an evaluation period).
Note: the port that you want to monitor must first be connected to the "IO Ninja" program, and then opened in a third-party application whose exchange with an external device you want to track.
Just to test that the hardware is working, you could perhaps boot a Linux live CD and run the statserial and/or minicom program to verify that it works. The Knoppix distribution seems to contain both those programs.
Serial ports on Linux are named /dev/ttyS0 for COM1, /dev/ttyS1 for COM2, etc.
