Load multiple windows problem

[p-designs]

Hello,

After figuring out how to add a wndproc to a seperate class and handle a window I've come across a new problem:

In my main.cpp file I load a window with classname "PokerMain" and then create a class of type CardTable. When CardTable is initialized it is supposed to load a window of classname "PokerTable" but does not appear - that is, unless I change the window so that it's parent is HWND_DESKTOP rather than identifying PokerMain's hwnd as it's parent, then it appears after the PokerMain window is closed.

However, when using PokerMain's hwnd as the parent and loading the application I close PokerMain's window yet the program is not terminated. So the PokerTable window is loaded but not visible?

Heres a snippet for the code:


CardTable::CardTable(char* sBackground, int width, int height, HWND hWndParent){
HINSTANCE hInst = GetModuleHandle(NULL);
char szClassName[] = "PokerTable";
WND_WIDTH = width;
WND_HEIGHT = height;
hMemDC = 0;
origDC = 0;

hBackground = LoadBitmapFile(sBackground);
cm.gDeck = cm.createDeck();
hRichEdit = LoadLibrary("RICHED32.DLL");

RegisterWindowClass(szClassName, hInst);

hWnd = CreateWindowEx (0, szClassName, "John's Poker Table", (WS_CLIPCHILDREN | WS_OVERLAPPEDWINDOW) & 0xFFFEFFFF, CW_USEDEFAULT,
CW_USEDEFAULT, WND_WIDTH, WND_HEIGHT, hWndParent, 0, hInst, this);

ShowWindow (hWnd, 1);
<more code here>
}


And my main.cpp (PokerMain) has this:

hwndMain = CreateWindowEx (0, szClassName, "Poker Main", (WS_CLIPCHILDREN | WS_OVERLAPPEDWINDOW) & 0xFFFEFFFF,
CW_USEDEFAULT, CW_USEDEFAULT, 800, 600, HWND_DESKTOP, 0, hThisInstance, NULL);
ShowWindow(hwndMain, 1);
CardTable cd("pokerbgd.dat", 800, 600, hwndMain);


Any help is greatly appreciated.

Your code snippet does not really show what you are trying to accomplish. I also do not quite understand what do you mean by load window,

One thing: you are referring to one window as a parent of another window. You can establish parent-child relationship between windows only if you pass parent’s handle and window style (among others) is WS_CHILD; that is mutually exclusice with WS_OVELAPPED and WS_POPUP.

If you pass handle to existing window calling CreateWindowEx, newly created window will be owned by a window indicated by passed handle. This is owner-owned relationship.

Another thing, you pass 1 as parameter when calling ShowWindow. By coincidence (or maybe on purpose) SW_HIDE is defined as 0 and SW_SHOWNORMAL defined as 1. Instead hard coded values, you should use macros SW_SHOW being used most often; it is defined as 5.

I am not sure what purpose (WS_CLIPCHILDREN | WS_OVERLAPPEDWINDOW) & 0xFFFEFFFF part serves. Is it to remove WS_MAXIMIZEBOX style?
