    The maximum number of stack frames supported by Visual Studio has been exceeded.

The message that is sent always is 528 this is 0x210 = WM_PARENTNOTIFY The wParam = 77594625, lParam = 3409408

I don't know what is the reason for that, and how to stop it, I searched the childs if any of them send any message to the parent, but there is no messages, the dialog is not shown , but it's window handle was created and the custom control also has got a handle and it's first child has got a handle then we are stuck with the crash and the other childs didn't got the chance to be created. I traced the execution and got that the crash happen after calling the create method of the child of the custom control inside the dialog. The custom control is a database navigation control that contains buttons for the next, previous, new, edit to enter record number, this custom control is inherited from TControl which is inherited from CWnd. the buttons inside it are inheriting from TButton which inherits from CButton.

UPDATE

The problem was as the following:

when I registered the custom control window class I set the windowproc to the MFC windowProc , when the MFC proc didn't find any method to eat the message it called the default proc of the window which is the MFC windowPoc that caused an open recursion, I fixed that by setting the window proc to the default one like the following

WNDCLASS wndClass;
//fill the window class data
wndClass.lpfnWndProc = ::DefWindowProc;//AfxWndProc;//this fixed it

that fixed my problem

Was it helpful?

Solution

I updated the answer to contain the solution of that problem, but in response to @Michael Walz I added the solution to this answer
