MDI muilti edit control app crashes. why

[xandaz]

    Hey. I'm making a multiple document interface app with multiple edit controls. the application crashes sometimes when loading the text files. does anyone know anything about this? thanks in advance

You are kidding, xandaz... "help, my program crashes" without any code???

[xandaz]

   sorry.... i thought someone might have been through the same issue. I'll givre you the code right away.

The culprit is LoadIconW in mdichild.asm
If you replace that with LoadIcon, 0, IDI_HAND you've got an icon but RegisterClass fails for other, unknown reasons.

I can't tell you more because I don't have the energy to deal with a project that has no comments and is distributed over a dozen files. Sorry to be rude but you should rethink your approach to programming.

[xandaz]

   ok ... i'll think about that. Thanks JJ.

Hi Xandaz!

Look like something is pointing nowhere.

I only can see a window popup without any parent

I only get an empty messagebox with OK button
invoke with a missing addr to filename in CreateFile or somewhere else?

you could check for invoke's that return eax==NULL afterwards with Messagebox =found one problem with failed api call

or use debugger to singlestep the suspicious area

well I prefer m2m macro,than bare metal push/pops because if forget one push or one pop get unbalanced stack

If you had read my answer above, you would know that it's "somewhere else"

@xandaz: If you comment out this line, you will see a window; however, there are heap errors afterwards - test the Open menu.

        invoke  InitCommonControlsEx,addr iccx
        ; invoke  ManageOpenMode,0

Hi Xandaz!

You have:

Code Select Expand


        invoke  ManageOpenMode,0
        invoke  WinMain,hInstance,0,0,SW_SHOWNORMAL


and must be:

Code Select Expand

        invoke  WinMain,hInstance,0,0,SW_SHOWNORMAL
        invoke  ManageOpenMode,0


[jj2007]

@HSE: That doesn't solve it. Of course, the call does no harm right before ExitProcess, but check the Open menu.

[xandaz]

    the manageopenmode was put there test purposes only.

Ok. ManageOpenMode crash before WinMain.

Even if you comment it out, the program crashes when you use the Open menu.
