Create and Show multiple CFrameWnd objects

abugg · #1 28-Apr-2009, 12:42

Hi,

I have created a CFrameWnd based class (CControlFrame) with many buttons, CEdits, etc.
I have successfully created and one instance of my CControlFrame class with the following code:

CPP / C++ / C Code:

CGenerator pattern1;
		CControlFrame* myFrame1 = new CControlFrame(pattern1, 1);
		if (!myFrame1->Create(NULL, L"Control Window #1", WS_OVERLAPPEDWINDOW,
			CRect(0,0,256,768)))
		{
			// free the memory and return
			delete myFrame1;
			return FALSE;
		}
		myFrame1->ShowWindow(1);

m_pMainWnd = myFrame1;

I am attempting to create a 2nd CControlFrame object to display simultaneously with the following code for the 2nd object.

CPP / C++ / C Code:

CGenerator pattern2;
		CControlFrame* myFrame2 = new CControlFrame;
		
		if (!myFrame2->Create(NULL, L"Control Window #2", WS_OVERLAPPEDWINDOW,
			CRect(256,0,512,768),myFrame1->GetTopLevelFrame()))
		{
			// free the memory and return
			delete myFrame2;
			return FALSE;
		}
		myFrame2->ShowWindow(1);

An Assert error is produced while attempting to create the myFrame2

CPP / C++ / C Code:

ASSERT(pWnd->m_hWnd == NULL); // only do once

I am guessing this is because the pointer is already pointing to the myFrame1?

The goal is for each frame to contain identical controls and layout with the ability to modify their own variables.

If this is the incorrect solution for such a problem, please let me know and possibly suggest an alternative approach?

Otherwise, any wild guesses, or advice would be greatly appreciated!
