ASP.Net error "Unable to start program http://localhost:123/myapp/" - asp.net

Well since i installed IE 8 i get this error so i cant debug my asp.net page :(
"Unable to start program http://localhost:123/myapp/"
Could not find the element(or some thing like that translated from swe)
What must i do to get rid of this error? and IE more or less hangs after this, the window does respond but it only loads half of it components...
Edit: Is there any way to set what browser to use when debugging befor i installed IE8 i normaly used opera and it worked like i wanted it to...

i think you IE 8 is not properly installed try setting other browser as default browser.
if you don't get this error then it means you have to re install ie 8 again

Hi all these type of user i had resolved this error so u also must try it as follow below steps:
This is one of the various errors that appear when you are debugging and may haunt you until you do the following fix:-
In the Internet Explorer, "Tools" Menu, select "Internet Options".
Switch to "Security" Tab.
Click on "Internet" (The Globe Icon. Its actually the default selected).
Click on "Custom Level" in the bottom.
Scroll down to find the "User Authentication" section.
Select "Automatic logon with current username and password".
OR Anonymous logon.
Click "Ok" twice to exit.
Restart IE. (You don't need to reinstall your browser.)

Maybe you are facing this known issue? This blog post also describes a workaround.

chrome is forcing https error for css and js files(Error - ERR_CERT_COMMON_NAME_INVALID)

Facing ERR_CERT_COMMON_NAME_INVALID, while loading css and js files in chrome browser.
While loading login.aspx page related css and js files are loading in IE and Mozilla where as in chrome its not loading. We have deployed the existing application in new server, same application is working on different server. Is there any configuration to be modified in IIS? I have verified both the environment which looks identical, any specific related configuration is helpful. please find the screen shot below
Screen shot
ERR_CERT_COMMON_NAME_INVALID is a very popular SSL error during loading the website. In most cases, the issue is due to certificate misconfiguration on a server. However, it may appear due to antivirus and firewall or aother third-party extensions. so you can try the following methods to solve the problem.
Check date and time are proper
Your Chrome browser will show ERR_CERT_COMMON_NAME_INVALID error in case the date and time are wrong on your computer or mobile device. Please recheck and adjust it on your via PC settings.
Check browser extensions
In some cases, the problematic browser extension could be a reason for the error. First of all, try to open the website in Incognito window and if that solves the issue then no need to check extensions. Otherwise, follow the next steps:
1.Click the "three dots" button on the top right corner of your browser window
2.Select More tools and Extensions
3.Turn off extensions one by one to find culprit extension and delete it to fix the browser error.
Check Installed SSL certificate
In Chrome, you have to click to the "Not Secure" button located on the left side of the address bar, and then click to "Certificate". There you will see the details of SSL certificate using the field "issued to".
Clear the SSL cache
The browser's SSL cache can be an issue. You have to try clearing the cache to resolve the error. click "Three dots" button on the top right side of the browser, find the "Settings". There you will find "Advanced settings" at the bottom of a page. Now find "Open Proxy Settings" and there you will see the "Content" tab with "Clear SSL state"

Unable to find firefox developer edition event listener breakpoints in the debugger?

In Chrome, a user can open up the DevTools Debugger and easily select an event listener breakpoint on the right in the "Sources" Pane.
I have been unable to find these features in the Firefox Developer Edition debugger. Curiously, when visting the Firefox Developer Edition website, they have a video that shows a user easily opening up the inspector, switching to the debugger, and clicking a panel on the right to bring up all these event breakpoints. In the version of Firefox Developer Edition that I am using (54.0a2), however, these buttons do not exist.
I have literally clicked every button on the debugger panel and am left scratching my head.
It seems almost unbelievable these features do not exist or were removed in a "developer edition" browser. Hoping someone can point me in the right direction.
Setting breakpoints on event listeners is obviously not yet implemented in the new debugger UI, but there's already a request to add it.
Note that you can simply switch back to the old debugger frontend by unchecking the Enable new debugger frontend option in the settings (only available in Firefox Nightly):
or by going to about:config and setting the preference devtools.debugger.new-debugger-frontend to false.

My aspx page gets struck half the way during load in internet explorer

In my project(classified site) there are many aspx pages. in that i have post page where user can post the ads.. This page is not loading fully.. only half of the page loads and then it stops. This happens only in Internet Explorer(I am using version 8.0)
Browser returns follwing errors:
Message: HTML Parsing Error: Unable to modify the parent container element before the child element is closed (KB927917)
Message: Object doesn't support this property or method
prototype.js
Please help me in this.
Have you checked your JavaScript or maybe JQuery codes?
Try to call that codes when the page is loaded.
Another solution is this:
Reset your internet explorer settings and run it. You can do this by following the steps given below.
If the problem is caused by damaged or incompatible Internet Explorer settings or add-ons, you can usually resolve the problem by resetting Internet Explorer settings.
To use the Reset Internet Explorer Settings feature from Control Panel, follow these steps:
Exit all programs, including Internet Explorer (if it is running).
If you use Windows XP, click Start, and then click Run. Type the following command in the Open box, and then press ENTER:
inetcpl.cpl
If you use Windows Vista, click Start Collapse this imageExpand this image . Type the following command in the Start Search box, and then press ENTER:
inetcpl.cpl
The Internet Options dialog box appears.
Click the Advanced tab.
Under Reset Internet Explorer settings, click Reset. Then click Reset again.
When Internet Explorer finishes resetting the settings, click Close in the Reset Internet Explorer Settings dialog box.
Start Internet Explorer again.
I ran into a similiar problem and this didnt help but I did find that the client had used the Ctl+Scroll and had Zoomed out to far causing the menu at the top of the page to start stacking.
Hope this helps though this post is older.

How to see the actual server side error message in the browser?

I'm having a trouble reproducing an issue a user is having in IE, but something that always bugged me is how can I see the error message from classic ASP page in IE for example on a dev server.
In IE all I see is for example:
This page contains programming error
And that's it.
Note: since this is server side, it applies to all browsers.
I remember this one!
You need to go into ie settings > advanced > uncheck "show friendly http errors"

Visual Studio | ASP.NET Configuration error

I have a problem as I have struggled with for a week.
Now I give up! I really can not figure out how to solve it. Every time I open the ASP.NET Configuration in VS10, then comes the first with this error:
**An error was encountered. Please return to the previous page and try again. **
If I then press:
How do I Use this Tool
so this comes up:
**Tool Has Timed Out
As a security measure, the Web Site Administration Tool times out after a period of inactivity. Changes to machine.config or web.config may also result in the tool needing to be restarted. To continue configuring your web site, restart the tool. **
Some who can answer me on what's happening here?
"Special characters in the path may be the problem, according to the posts." as Posted above by Dave Swersky
THIS worked perfectly for me! I had a special character ("#") in my folder path I removed this and removed spaces for good measure!
I was getting the error "Tool has timed out" among other errors when accessing the WSAT(Web site administration tool) from the ASP.NET configuration menu item.
I saw a post somewhere else that said the problems was solved when the default browser was changed to Internet Explorer. I have been using Firefox and have the exact same problem. When I changed the default browser to IE, the configuration page came up with no problem. But it won't work twice in a row without going in and setting the default browser back to IE each time. When I go back in to Program Access and Defaults, "Use by current browser" is selected. I have to reselect IE, and then it will work one time.
Judging by the Connect site, this error has been reported and is not well understood:
http://connect.microsoft.com/VisualStudio/feedback/details/118567/an-error-was-encountered-please-return-to-the-previous-page-and-try-again
Special characters in the path may be the problem, according to the posts.
This is what worked for me.
I'm using Visual Studio 2010 trying to create the membership role. I was trying to use the ASP.NET Configuration in Visual Studio.
Set the 'Default Browser' to Internet Explore.
To do this:
Right click on one of the .aspx pages you have under "Solution Explorer".
Select "Browse With..."
Select Internet Explore and Click on Set as Default.
Close the box.
Go back and click on "ASP.NET Configuration"
This will automatically open Internet Explorer.
Problem Solved :D
I guess what I was doing wrong was using Firefox as the default browser with Visual Studio. I'm guessing Visual Studio works good together with Internet Explorer since Momma and Daddy made them together (awww how cute)
The issue might be related to an application path that has spaces. After googling I managed to bypass the issue by appending the application path to the url manually ie.
http://localhost:{your_port_here}/asp.netwebadminfiles/default.aspx?**applicationPhysicalPath={path_to_your_application}&applicationUrl=/**
As a firefox user, I closed firefox then executed the "ASP.NET Configuration" option in VS2010. It automatically opens firefox (default browser) and now I am seeing WAT page contents.
