Try "WS_POPUP" as the style of the window if you want it to have no titlebar.
You receive a "WM_LBUTTONDBCLK" message when the window is double clicked with the left mouse button, and "WM_RBUTTONDBCLK" when the window is double clicked with the right mouse button.

You also have to specify that the window is able to recieve double clicks at creation. Check the WNDCLASSEX, or the CreateWindowEx Documentation for more info.

WNDCLASS wc;
wc.style = CS_DBLCLKS | CS:HREDRAW | CS_VREDRAW;

ok now i have a window that has no caption is topmost and recieves dblclk msgs, cool

question though the window displays the waiting cursor is there a reason for that and is there a way i can remove the window from the taskbar..?

here is my WNDCLASSEX and createWindowEx as they are now

BOOL initBoard(HINSTANCE hInstance){
    
	WNDCLASSEX mCls; 
	HBRUSH hBrush;

	hBrush = CreateSolidBrush(RGB(0,0,0));

    // Fill in the window class structure with parameters 
    // that describe the main window. 
	mCls.cbSize = sizeof(mCls);
    mCls.style = CS_OWNDC | CS_DBLCLKS;								// redraw if size changes 
    mCls.lpfnWndProc = wndProc;											// points to window procedure 
    mCls.cbClsExtra = 0;												// no extra class memory 
    mCls.cbWndExtra = 0;												// no extra window memory 
    mCls.hInstance = hInstance;											// handle to instance 
    mCls.hIcon = NULL;				// predefined app. icon 
    mCls.hCursor = NULL;							// predefined arrow 
    mCls.hbrBackground = hBrush;										// default background color 
    mCls.lpszMenuName =  0;												// no menu resource 
    mCls.lpszClassName = "rBoard001";									// name of window class 
	mCls.hIconSm = NULL;			// load the title bar icon
    // Register the window class. 
 
    return RegisterClassEx(&mCls); 
} // End initBoard(); 





BOOL createBoard(HINSTANCE hInstance, int nCmdShow){
	
	HWND hWnd; 
    // Create the main window. 
 
    hWnd = CreateWindowEx(
		WS_EX_TOPMOST,
        "rBoard001",														// name of window class 
        NULL,            // title-bar string 
        WS_POPUP | WS_MAXIMIZE,												// top-level window 
        0,														// default horizontal position 
        0,														// default vertical position 
        640,																// default width 
        480,															// default height 
        (HWND) NULL,														// no owner window 
        (HMENU) NULL,														// use class menu 
        hInstance,															// handle to application instance 
        (LPVOID) NULL);														// no window-creation data 
 
    if (!hWnd) 
        return false; 

    // Show the window and send a WM_PAINT message to the window 
    // procedure. 
    ShowWindow(hWnd, SW_SHOW);//|SW_MAXIMIZE
	UpdateWindow(hWnd); 
    return true;
} // End createBoard();

To display the normal cursor, change this line:

mCls.hCursor = NULL;

to

mCls.hCursor = LoadCursor(NULL,IDC_ARROW);

this is only my second windows app so i am still learning the window class setup and creation ins and outs

thanks guys
