I have found 2 examples on the internet. Both of them worked. One looked nice, but was limited to the message loop, and the other one was crap but used PeekMessage() instead GetMessage() so you can also do things outside of that loop. So i tried to add the PeekMessage() to the good one, but for some reason it does not close. (msg.message == WM_QUIT) is never true. Even when i use WM_CLOSE instead, it is still false, even though the WM_CLOSE message does get dispatched. So the window disappears but visual studio stays in the debugger. So i seriously do not understand what the hell is going on, to me it seems like its going beyond logic. But the debugger is always right, so i must have screwed up somewhere
.
Here is my code:
GeSHi (cpp):
#include <windows.h>
const char g_szClassName[] = "myWindowClass";
// Step 4: the Window Procedure
LRESULT CALLBACK WndProc(HWND hwnd, UINT msg, WPARAM wParam, LPARAM lParam)
{
switch(msg)
{
case WM_CLOSE:
DestroyWindow(hwnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
}
return DefWindowProc(hwnd, msg, wParam, lParam);
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG msg;
bool exitapp=false;;
//Step 1: Registering the Window Class
wc.cbSize = sizeof(WNDCLASSEX);
wc.style = 0;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wc.hCursor = LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+1);
wc.lpszMenuName = NULL;
wc.lpszClassName = g_szClassName;
wc.hIconSm = LoadIcon(NULL, IDI_APPLICATION);
if(!RegisterClassEx(&wc))
{
MessageBox(NULL, "Window Registration Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
// Step 2: Creating the Window
hwnd = CreateWindowEx(
WS_EX_CLIENTEDGE,
g_szClassName,
"The title of my window",
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, CW_USEDEFAULT, 240, 120,
NULL, NULL, hInstance, NULL);
if(hwnd == NULL)
{
MessageBox(NULL, "Window Creation Failed!", "Error!",
MB_ICONEXCLAMATION | MB_OK);
return 0;
}
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
// Step 3: The Message Loop
while (!exitapp)
{
PeekMessage(&msg,hwnd,NULL,NULL,PM_REMOVE);
if (msg.message == WM_QUIT)
{
exitapp=true;
}
else
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
}
return msg.wParam;
}
