Simple Windows GUI Application " The system cannot find the file specified"
I'm using DevC++
And I get this error:
The system cannot find the file specified
even though windows.h does exist, and I'm using Windows XP SP2
Heres my code:
Code:
#include <windows.h>
LRESULT CALLBACK WndProc ( HWND, UINT, WPARAM, LPARAM );
static char sClassName[] = "MyClass";
static HINSTANCE zhInstance = NULL;
int WINAPI WinMain ( HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow ) {
WNDCLASSEX WndClass;
HWND hwnd;
MSG Msg;
zhInstance = hInstance;
WndClass.cbSize = sizeof(WNDCLASSEX);
WndClass.style = NULL;
WndClass.lpfnWndProc = WndProc;
WndClass.cbClsExtra = 0;
WndClass.cbWndExtra = 0;
WndClass.hInstance = zhInstance;
WndClass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
WndClass.hCursor = LoadCursor(NULL, IDC_ARROW);
WndClass.hbrBackground = (HBRUSH) (COLOR_WINDOW+1);
WndClass.lpszMenuName = NULL;
WndClass.lpszClassName = sClassName;
WndClass.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
if (!RegisterClassEx(&WndClass)) {
MessageBox( 0,"Error registering Class!","Error!",MB_ICONSTOP | MB_OK );
return 0;
}
hwnd = CreateWindowEx( WS_EX_STATICEDGE, sClassName, "my first gui! in win32 :P", WS_OVERLAPPED_WINDOW, CW_USEDEFAULT,
CW_USEDEFAULT, 320, 240, NULL, NULL, zhInstance, NULL
);
if (hwnd == NULL) {
MessageBox(0, "Error Creating Window!", "Error!", MB_ICONSTOP | MB_OK );
return 0;
}
ShowWindow(hwnd,nCmdShow);
UpdateWindow(hwnd);
while (GetMessage(&Msg, NULL, 0, 0) ) {
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return &Msg.wParam;
LRESULT CALLBACK WndProc ( HWND hwnd, UINT Message, WPARAM wparam, LPARAM lparam ) {
switch(Message)
{
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hwnd,Message,wParam,lParam);
}
return 0;
}
}
}
