I have a C++ DLL that some other programs use. I set SetUnhandledExceptionFilter in the DLL to catch any application crashes. The application crashes, the DLL's ProcessDetach isnt called, but this filter function isnt called either. Any tips for debugging this problem?
thanks!

Maybe someone called ExitProcess? put a breakpoint in ExitProcess and track back the call stack..

If that is the case my DLL's ProcessDetach should be called right? Other possibility is TerminateProcess is called.

I will try this. Although I only have release version of the application - I am not sure if I am going to get the call stack to see.
thanks!

Maybe another module called SetUnhandledExceptionFilter and replaced your handler but isn't calling yours. It is unusual for a DLL to call this API - Normally you'd do this kind of thing in the .EXE. You could place a breakpoint inside SetUnhandledExceptionFilter and check for this.

How do we detect that? How do find out the currently set unhandled exception filters, if any?

Actually, it used to work earlier. Due to some changes this regressed. I only need tips to debug this.

As I said I already have a message box as the first statement in SetUnhandledExceptionFilter filter, and that doesnt come up. So I am assuming my filter isnt called at all 
thanks!

I would use WinDBG as follows:
1. Start the process in question.
2. Type "bp kernel32!SetUnhandledExceptionFilter" in the command window.
3. Press F5.
4. When the breakpoint is hit look at the stack.
5. Goto step 3
This will show every call to SetUnhandledExceptionFilter made in the process. I would only pay attention to breakpoints that occur after your call to SetUnhandledExceptionFilter.

Hi,
I have a SDI application that I show a CListCtrl-derived control using the LVS_ICON style with a 24-bit color imagelist filled with 80x80 bitmaps to represent the items in the control. When I select an item in the control, it doesn't select properly. Only the text of the item is selected and it is gray as if the control doesn't have the focus. But the control does in fact have the focus. Why doesn't the item select properly, i.e., with a blue background?
Any help would be greatly appreciated,
Royce

Are you using a CListView?

No, the parent of the control is the CFormView created by the CSingleDocTemplate constructor when the application is created.
|
|

|

To ascertain whether it is the actual list control or the parent object (CFormView) causing the problem, I would suggest creating a temporary dialog-based project that contains the same sort of list control. Populate the list control in exactly the same fashion. Does it behave the same as the one in the SDI project?

Ok, I did as you suggest. I get exactly the same behavior. The items select just the text and are a dim gray.
|
|
|
|
|
I could post my test project, but I don't know if the forum would appreciate a 130 Kbyte post.

Can you supply a screenshot of the offending control?

You can't. You'll have to find a Web site that will allow such. There are a ton of them out there that can act as a repository.

Are you sure the ListCtrl still has focus?
You might try setting up an WM_KILLFOCUS handler for the list control and running it in the debugger or something. It sounds like the control has actually lost focus, which might not be apparent because if you click on it again it temporarily gets focus, handles your click on the item, and then possibly loses focus again.
Good luck!

I have already tried exactly what you suggest. The control is not losing the focus.
Thanks for your help.

First, I'd double-verify that it's not losting focus by clicking on the control, then clicking on another control and making sure that the OnKillFocus handler is actually being called when I expect it to (it's possible depending on your message maps and parent/child relationships that the view is eating the messages).
If that plays out, and you're confident that the control truly is not losing focus, could it be a problem with transparency of your images in the image list and the background color of the text (and the text not being transparent), simply not letting the blue "show through"?
|
|
|
|
|
Yes, I have just verified that the control is not losing focus when it should not. Its OnSetFocus() and OnKillFocus() handlers are being called appropriately. When I select an item, the OnSetFocus() handler is called. The OnKillFocus() handler is not being called until I actually do move the focus. I have used different types & sizes of bitmaps and different parameters in creating the imagelist, but no change in the control's behavior.
