I want to store the exported pdf file to clip board to be able to paste as an attachment in outlook. I'm using asp.net / vb and i've tried to import system.windows.forms in my web application to use the clipboard class.
any idea?
'here's my code:
Clipboard.SetDataObject(System.IO.Path.Combine("C:/Temp/", HttpContext.Current.Session("fileName")), True)
'this is the error after this process:
Exception thrown: 'System.Threading.ThreadStateException' in System.Windows.Forms.dll
An exception of type 'System.Threading.ThreadStateException' occurred in System.Windows.Forms.dll but was not handled in user code
Current thread must be set to single thread apartment (STA) mode before OLE calls can be made. Ensure that your Main function has STAThreadAttribute marked on it.
ASP.NET code is run on the back end side, i.e. server. So, accessing the Clipboard on the server doesn't make any sense. Instead, you can find a JavaScript code/component which can be run on the client browser.

I spend a lot of time to search answer but I didn't found it. We have console application (exe) with C1 Report Component for automated printing task. This application is executed from cmd file and cmd file is called by cmdexec from SQL Server 2014 every minute. It's work very fine but there is exceptiton GDI+ Initialize - System.Drawing.SafeNativeMethods+Gdip.Initialize aproximetelly montly. There is no chance to solve this so we must restart server.
I tried to create cmd file with echo command. It was worked fine and I got output from echo. So I created application with Console.Writeline("Hello world") only. It was worked fine. Then I add reference to System.Drawing. Nothing happend - ouput was produced. Then I created System.Drawing.Bitmap object and I got GDI+ Initialize exception.
Job on SQL server run as SQLRUNSERVICES and it is in Administrator group. But when I log as SQLRUNSERVICES and launch our application in command line, application works fine without exception. When I log as another user there is no problem with this. Only with SQLRUNSERVICES throught SQL Proxy.
I suppose there must be something wrong with windows session. This application starts, prints some reports and finishes. So I suppose when application finishes memory will be free and GDI object will be free so. I check if we have call dispose method for each object working with GDI.
Can I have some chance to see GDI objects used by session? Or what could cause this exception? I cannot use task manager because when application is not running there is nothing to see.
Thank you for replies. It is very stresfull problem for us because it is going repeatedly every month after restart server.
We created testing application to print most quickly and we got this exception for one day. We call Dispose method for C1Report ofcourse. We will try to use using section. But it looks like C1 error. Test application printed about 65000 count of document and then crashed by GDI+ Initialization Exception. There is stack:
System.TypeInitializationException: The type initializer for 'Gdip' threw an exception. ---> System.Runtime.InteropServices.ExternalException: A generic error occurred in GDI+.

I have a MorphX report (AOT report) that has been imported from 3.0. The problem is the class that starts the report is based off of RunBaseReport. It then sends in parameters from the dialog box. This all works client side. I want this to run on the batch server and schedule it to print out reports and email them.
The issue is in the init method. Where SalesReport is the above mentioned class that overrides RunBaseReport:
SalesReport = element.args().caller();
This line doesn't work when coming from the batch server. So then when I try to call SalesReport.parmDate() I get an
this object has not been initialized
error. Can this not be done from a batch server anymore or what are alternatives?
I'am using the inbound-channel-adapter from Spring Integration to retrieve files over sftp from a remote server. Everything works fine.
But I have an additional requirement: after a file is received on the local side, that file needs to moved to a "send" directory on the remote server.
The "SFTP Outbound Gateway" has the appropriate method for that move action, but my problem is when to call it.
Situation: 10 files on remote server, 0 on local server
When I start my application it will receive all 10 files from the remote server and write them to my local file system. Perfect.
Situation: 1 file on remote server, 10 on local server
In this situation the remote file is received, but for every file on the local file system the receive method of the QueueChannel is also called.
Example log from one file: (file1.zip)
18:12:52.118 [task-scheduler-1] INFO o.s.i.file.FileReadingMessageSource - Created message: [[Payload File content=C:\Downloads\sftpTest\file1.zip][Headers=...]
18:12:52.119 [task-scheduler-1] DEBUG o.s.i.e.SourcePollingChannelAdapter - Poll resulted in Message: [Payload File content=C:\Downloads\sftpTest\file1.zip][Headers=...]
18:12:52.119 [task-scheduler-1] DEBUG o.s.integration.channel.QueueChannel - preSend on channel 'fromChannel', message: [Payload File content=C:\Downloads\sftpTest\file1.zip][...]
18:12:52.119 [task-scheduler-1] DEBUG o.s.integration.channel.QueueChannel - postSend (sent=true) on channel 'fromChannel', message: [Payload File content=C:\Downloads\sftpTest\file1.zip][Headers=...]
18:12:52.119 [main] DEBUG o.s.integration.channel.QueueChannel - postReceive on channel 'fromChannel', message: [Payload File content=C:\Downloads\sftpTest\file1.zip][Headers=......]
So even when the file it not physicaly retreived from the remote server, the channel.receive() method will still receive a message with that file as payload.
This confuses me, because I can't determine from the message if the file was already on the local file system or was just retrieved from the remote server.
I experimented using a custom org.springframework.messaging.support.ChannelInterceptorAdapter, FileFilter, ServiceActivator, but the problem still remains.
My application will process high volumes, so sending the received file to the required directory on the remote server is not an option. And also simply trying to move the file remote for every message that is locally received, is not an option since it will clutter the logfiles with exceptions of not being able to move the file. This way in case of an real error situation the problem will not be detected.
One solution might be a hook in the method copyFileToLocalDirectory of the org.springframework.integration.file.remote.synchronizer.AbstractInboundFileSynchronizer.
There is a check performed if the remote file should be deleted and that loop is only called for the files that were actually transferred from the remote server. My attempts to override this method and add my move behaviour did not succeed, since Spring has already instantiated the classes
that will handle this.
So what is the best way to achieve this? I know the problem will probably be located between my keyboard and my chair, but I've run out of options and any help is highly appreciated.
Thanks a lot,
Frank
You would probably be better off using MGET and an outbound gateway to retrieve the files instead of using the inbound adapter which, as you say, is two-stage - synchronize, and emit message(s) for file(s) in the local dir (unless you use a persistent file list filter, in which case you'll only see "new" files).
Meteor is said to automagically (in most cases) figure out what code to run on the client and what code to run on the server so you could theoretically just write all your code in one .js file.
I would like to be able to write code in my browser console and have it executed pretty much as if I had put the code in a file on my server.
For example, in my browser console:
[20:08:19.397] Pages = new Meteor.Collection("pages");
[20:08:30.612] Pages.insert({name:"bro"});
[20:08:30.614] "sGmRrQfezZMXuPfW8"
[20:08:30.618] insert failed: Method not found
Meteor says "method not found" because I need to do new Meteor.Collection("pages"); on the server.
But is there a workaround for this, whether using the above-mentioned automagic or by explicitly saying in my browser console "run the following line of code on the server!"?
Well it doesn't "automagically" figure it out - you have to very explicitly do one of two things:
Separate the code into client and server directories.
Wrap the code in an isClient or an isServer section.
Otherwise, any code you write will execute in both environments. However, any code input by the user on the client will only be executed on the client. Meteor has been specifically designed to protect this boundary.
You can call a method on the server from the client, but again the server cannot be tricked into executing client-defined functions.
In your specific example, you can always define the collection only on the client like so:
Pages = new Meteor.Collection(null);
That will allow you do freely manipulate the collection data on the client, but it will not involve the server (nothing will be stored in the db).
I'm trying to create a Flex based internet application with an EJB layer in the server. This layer provides the XML used by the flex application. It uses the Cairngorm architecture. Currently, on an error I call the handler function defined in all the command files. How can I centralize this?
My idea is to create a XML file that contains all the error messages and the types of error message eg:- Warning, Error etc. In the error handler, I will call the error handling function and pass a unique id which in turn will display the error message defined in the xml config file. Do I need to load this XML file in the Model layer of the application itself and store them as say global variables?
Please suggest me ideas on overriding the Alert box so that I can create Warning alert, Error alert etc.
Load the xml file when the app loads, and store the messages on a model. When you need to fire off an error message, you can fire the appropriate event, and you can have a command that pulls the right one from the model and displays it. Alert is definitely the way to go if you want to have a command open a window.
The better (but harder) option is to have a view that binds to a model, which model has a property like "hasError" and "errorMessage", so if hasError gets set to true, the view opens a custom popup.
TitleWindow is not good enough?
