Sep 1, 2006I am a *** programmer and cannot make sense of the error message I'm getting. I wrote a program and it runs fine on my development machine and also on other machines with Visual Studio installed. However, when I run it on any other machines, I get the message below.All of my other programs that I write run fine on these other machines; so I know this problem must be due to some control that's unique to this new program. But I can't make much sense of the error report

Simple right? Guess not...-Textbox1 is the textbox in wich you input text.-Label1 is the label on the popup window that tells you what to do. It's text is either "Edit name:" or "Input name:"This is the function if you click "OK".

Jun 2, 2011I got a serious problem. Though I have made my program newly it shows error. I have used 1280,1024 animation only for first form then used 1280,1024 image for every form. Today I was checking then it was showing me error message for 19th & 20th form. If I use On Error Resume Next then it shows error for another form ; if I use same code there in the menu item I mean so that I can get rid of error when I click to show a form it shows another error. First error message is "InvalidOperationException was unhandeled An error occurred creating the form. See Exception.InnerException for details. The error is parameter is not valid." and second error is "OutofMemoryException was unhandled Exception of type 'System.OutOfMemoryException' was thrown".

Exception Handling - Can't Catch COMException
Feb 24, 2012I use the following code to access a VSS item:
Dim sItem As String = "$/MyVssProject/InexistentFile.txt"
Dim oItem As SourceSafeTypeLib.VSSItem = Nothing
Try
[Code]....
The problem I face is when I try to get an instance to a file that doesn't exist in the VSSDB, thus leading to a COMException, which basically wouldn't be of a problem (I would expect). In fact the exception occurs, but instead of proceeding with the catch code, the debug cursor stays on the line "oItem = m_oSourceSafe.VSSItem(sItem)", showing a dialog with title "COMException crossed a native/managed boundary.
From here the execution doesn't proceed, until I change the content of sItem to an existing file.
Why does the exception not get caught, and how can I achieve it?

Random ComException With Excel Automation?
Jun 16, 2011I have done quite a bit of research on this issue and haven't came up with anything definitive yet. I am having issues with Excel randomly getting ComExceptions while writing out reports. I am using a Visual Basic 2005 (framework 2.0) console application to create these reports. The problem has been difficult to figure out because it occurs in random places while writing out reports so I can't catch the error to see the problem. I have looked through the differing items that it breaks on and there is nothing odd about them that would cause any of these problems.
