    Angry Dialog Boxes

    Okay I created a dialog box in my windows program and everytime I close the dialog it closes my entire program. I checked it and for some reason I am recieving the WM_DESTROY message after I close the dialog!

    Here is a bit of the code:

    Code:
    // processed by the WM_COMMAND in my MainWndProc
    case IDM_ADCHAR:
    					adchar = DialogBox(g_hInst, IDD_ADCHAR, NULL, ADCharDlgProc);
    					break;
    
    BOOL CALLBACK ADCharDlgProc(HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam)
    {
    
    	switch(message)
    	{
    		case WM_INITDIALOG:
    			return(TRUE);
    
    		case WM_COMMAND:
    
    			switch(LOWORD(wParam))
    			{
    				case IDD_ADCHAR_OK:
    					EndDialog(hwnd, IDD_ADCHAR_OK);
    					return(TRUE);
    					
    				case IDD_ADCHAR_CANCEL:
    					EndDialog(hwnd, IDD_ADCHAR_CANCEL);
    					return(TRUE);
    
    				default:
    					return(TRUE);
    			}
    			return(TRUE);
    			break;
    	}
    
    	return(FALSE);
    
    }
    Thats the only code that deals with the dialog. If you need anymore I can post more, but I'm just wondering why I'm recieving the WM_DESTROY message after closing the dialog box?

    Thanks in advance!

    This is my best guess: It might be sending the WM_DESTROY message for the dialog Handle and not the main window. You need to check which handle is being destroyed.

    My problem is that I KNOW that my main window is being destroyed. I see it happen. I click "okay" or "cancel" on my dialog and it closes my entire program. I did a check and I made it so then if my main window gets a WM_DESTROY message it will inform me via a message box. And I get that message box everytime I close the dialog.

    Any other suggestions?
