I have been getting sometimes with SOME libraries (be it included in the framework or not).[code]I'd expect the func.Call() to return an exception if something is up, or do anything to error out, but here it just murders my method which returns instantly! The same stuff here is also in a loop, which doesn't get any more iterations, it just stops executing this function and continues running the program.

In debug mode I get into a line that evaluates to false because the expression cannot be evaluated because of "Cannot evaluate expression because the code of the current method is optimized." Program does not assert or error out. If Item.Length then . . . (Here when I hover the mouse it displays "Cannot evaluate expression because the code of the current method is optimized"). What interesting is that it only occurs in one of .vb files.BTW, I'm programming in Compact Framework.
View 4 RepliesI am working on a project and the code for FORMS1.vb has become quite large, 20K lines.How can I break this down into more managable pieces. I have tried Modules but I get multiple reference errorsd when I move like all of the reporting code to a module. The report code has nothing to do with the forms other than being able to call that code from an object on the form.

View 9 RepliesIn my form there is a DataGridView, the user select information in the DataGridView then there are text boxes that needs to be filed in. So this is what needs to happens if the focus is on the DataGridView when the user hits the Tab key it moves the focus to first text box. Then once the user hits the last tab box it returns focus back to the DataGridView but to next cell. Initially figured this would not be a problem and did this code;
Dim PreviousCell As DataGridViewCell
Private Sub DataGridView1_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles DataGridView1.KeyDown

View 6 RepliesWhen I close my VB.NET application it occasionally yields the following error code: The program '[1584] Foo.exe: Managed' has exited with code -1073741819 (0xc0000005). This error only occurs when one of the MDI child windows is maximized and then the program is subsequently closed. When I step through the code, the error appears to be generated after the execution of my "custom" code is complete. What might be the cause of such an error? Where might I find more information about this exit code (Google and Bing were little help - maybe I didn't search for the right thing)?

View 1 RepliesI'm having a bit of a problem getting my application to close properly. Basically I have one main form from which all other forms open. If a user tries to close that main form, I want to bring up a MessageBox asking if they want to exit the application.However, when I try to do that it asks the question twice. It seems that the Application.Exit() is triggering the FormClosing event again for some reason, but I don't know of another way to exit the application. BTW, the main form isn't the startup form so I can't use the option to close when the startup form closes.
View 9 RepliesNow I have a sub to validate a bunch of textboxes and combo boxes.I previously used many IF statements to validate and pop up different messageboxes and Exit Sub in every IF statement.But I heard that too many Exits will decrease the efficiency and they were not recommended to use. Instead, nested IF is better because it will let the process naturally go to the end.Then I found out that if I use nested IF,it will be hard to read, since messageboxes are all separated from conditions.

But while I actually have the code up in the IDE, and simply adding/deleting code the whole IDE will randomly crash (usually without warning) and I loose my changes since last save.If/when I do get some hint of why it crashed, I get a window about illegal whitespace or something.... but that's rare ... usually it just crashes without warning and the whole IDE completely shuts down instantly. just deleting/adding a character is enough to trigger it maybe once every 30 minutes.
This is on a computer that is otherwise very rock solid .... no other program ever crashes, etc.

I'm having a bit of trouble learning the uses of partial classes. I know they are used to split a class into several pieces for convenience but I don't understand how to put all of this into play. I'll show you what I mean here:

Public Interface ICar

OK, now that I have all of that, how do I put it to simple use in my partial class "OffRoader"? (You can add a "console.writeline" event to the methods if you want, in order to show me the uses of these partial classes.)
Is it possible to (programmatically) retrieve the current line of code being executed? For example, I have program X that's only 200 lines long.

I have a WinForms app in a single project written in VB.Net 2003 (legacy code). There is a MainForm and a SecondaryForm that is run by the MainForm. When I run the app thru the MainForm, I can debug with no problem. However, if I just run the SecondaryForm, I get the debug error, "There is no source code available for the current location", when stepping over,_routeId = CInt(myVar)
At this point I am no longer able to debug thru my code window, but have to use the disassembled code.
when i run the application it gives an error "there is no source code available for the current location". Even i try to debug using f8 and msgbox in all forms,It doesn go thru it.I dont know what goes wrong with my application.All the while it goes perfectly alright.what does this error message meant and why all the way in sudden it happens to be like this?
