I have.... get this!.... created a BLANK WINDOW in c++ :) :) :). Sounds pathetic, but a window in C++ is a bitch to make:

#include


LRESULT CALLBACK WindowProcedure
(HWND hwnd, unsigned int message, WPARAM wParam, LPARAM lParam);

class WinClass
{
public:
WinClass (WNDPROC winProc, char const * className, HINSTANCE hInst);
void Register ()
{
::RegisterClass (&_class);
}
private:
WNDCLASS _class;
};

WinClass::WinClass
(WNDPROC winProc, char const * className, HINSTANCE hInst)
{
_class.style = 0;
_class.lpfnWndProc = winProc; // window procedure: mandatory
_class.cbClsExtra = 0;
_class.cbWndExtra = 0;
_class.hInstance = hInst; // owner of the class: mandatory
_class.hIcon = 0;
_class.hCursor = ::LoadCursor (0, IDC_ARROW); // optional
_class.hbrBackground = (HBRUSH) (COLOR_WINDOW + 1); // optional
_class.lpszMenuName = 0;
_class.lpszClassName = className; // mandatory
}

class WinMaker
{
public:
WinMaker (): _hwnd (0) {}
WinMaker (char const * caption,
char const * className,
HINSTANCE hInstance);
void Show (int cmdShow)
{
::ShowWindow (_hwnd, cmdShow);
::UpdateWindow (_hwnd);
}
protected:
HWND _hwnd;
};

WinMaker::WinMaker (char const * caption,
char const * className,
HINSTANCE hInstance)
{
_hwnd = ::CreateWindow (
className, // name of a registered window class
caption, // window caption
WS_OVERLAPPEDWINDOW, // window style
CW_USEDEFAULT, // x position
CW_USEDEFAULT, // y position
CW_USEDEFAULT, // witdh
CW_USEDEFAULT, // height
0, // handle to parent window
0, // handle to menu
hInstance, // application instance
0); // window creation data
}


int WINAPI WinMain (HINSTANCE hInst, HINSTANCE hPrevInst,
char * cmdParam, int cmdShow)
{
char className [] = "Winnie";

WinClass winClass (WindowProcedure, className, hInst);
winClass.Register ();

WinMaker win ("Hello Windows!", className, hInst);
win.Show (cmdShow);

MSG msg;
int status;

while ((status = ::GetMessage (& msg, 0, 0, 0)) != 0)
{
if (status == -1)
return -1;
::DispatchMessage (& msg);
}

return msg.wParam;
}




In delphi, to get a blank window, you just click "Run" w/o putting anything on the form :p
