    Windows Using Win32 API With M$ VC++

    Is There any special DWORDS missing from the MSDN library that would enable me to display a maximised window that has no titlebar and overlaps the start bar, I have found nothing as to date that i can use in the DWEXSTYLE bit of the CreateWindowEX API call any help would be great;
    THanx

    Don't think there's anything missing. Try the following params:

    dwStyle : WS_MAXIMIZE & WS_VISIBLE
    (Do not include WS_SYSMENU or WX_CAPTION)

    Include
    dwStyleEx : WS_EX_TOPMOST

    Do you mean to cover the whole screen?

    Code:
    #include <windows.h>
    
    LRESULT CALLBACK WndProc(HWND hwnd,UINT Message,WPARAM wParam,LPARAM lParam);
    
    int WINAPI WinMain( HINSTANCE hInst,
    					HINSTANCE hPreInst,
    					LPSTR lpszCmdLine,
    					int nCmdShow )
    {
    	HWND    hwnd;    
    	MSG     Msg;   
    	TCHAR   *szClassName = TEXT("SIMPLEWND");
    	WNDCLASSEX wcx = {0};    
    	
    	wcx.cbSize			 = sizeof(WNDCLASSEX);
    	wcx.style            = CS_HREDRAW | CS_VREDRAW;          
    	wcx.lpfnWndProc      = (WNDPROC)WndProc;               
    	wcx.hInstance        = hInst;                      
    	wcx.hIcon            = LoadIcon(NULL,IDI_APPLICATION);                         
    	wcx.hCursor          = LoadCursor(NULL,IDC_ARROW);                         
    	wcx.hbrBackground    = (HBRUSH)GetStockObject(BLACK_BRUSH);      
    	wcx.lpszClassName    = szClassName;                    
                             
    	if (!RegisterClassEx(&wcx)){
        	return 1;
        }
    
    	hwnd=CreateWindowEx(WS_EX_TOPMOST,                               
    	                    szClassName,                      
    	                    TEXT(""),            
    	                    WS_POPUP | WS_VISIBLE,                
    	                    0,   
    	                    0,   
    	                    GetSystemMetrics(SM_CXSCREEN),   
    	                    GetSystemMetrics(SM_CYSCREEN),    
    	                    NULL,                               
    	                    NULL,                               
    	                    hInst,                       
    	                    NULL);                              
    	
    	ShowWindow(hwnd,nCmdShow);
    	UpdateWindow(hwnd);
    	
    	while (GetMessage(&Msg,NULL,0,0)>0){
    	    TranslateMessage(&Msg);
    	    DispatchMessage(&Msg);
        }
    	return Msg.wParam;
    }
    
    LRESULT CALLBACK WndProc(HWND hwnd,UINT Message,WPARAM wParam,LPARAM lParam)
    {
    	switch (Message){
    		case WM_KEYDOWN:
    			if(wParam != VK_ESCAPE){//Press escpae to quit
    				PostQuitMessage(0);  
    				return 0;
    			}
    	    case WM_DESTROY:
    	        PostQuitMessage(0);  
    	        return 0;
    	    default:
    	        return DefWindowProc(hwnd,Message,wParam,lParam); 
        }
    }
