I suspect that for some reason the window isn't being destroyed properly. I have done many simple windows programs like this in the past and I am not sure why this one all of a sudden is acting up on me. It keeps running in the background even when I close the window, and it uses %100 of my processor so everything else in windows runs really slow.
Code:
#include <windows.h>
LRESULT CALLBACK MainWndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd ){
HWND Uber;
MSG msg;
WNDCLASSEX wc;
wc.cbClsExtra = 0;
wc.cbSize = sizeof(WNDCLASSEX);
wc.cbWndExtra = 0;
wc.hbrBackground = (HBRUSH)GetStockObject(WHITE_BRUSH);
wc.hCursor = LoadCursor(hInstance, IDC_CROSS);
wc.hIcon = LoadIcon(hInstance, IDI_ERROR);
wc.hIconSm = NULL;
wc.hInstance = hInstance;
wc.lpfnWndProc = MainWndProc;
wc.lpszClassName = "Main Window";
wc.lpszMenuName = "Main Window";
wc.style = CS_HREDRAW | CS_VREDRAW;
if(!RegisterClassEx(&wc)) {
MessageBox(NULL, "Could not initialize window", "ERROR", MB_OK);
return ERROR;
}
if(!(Uber = CreateWindowEx(NULL, "Main Window", "Main Window", WS_SYSMENU | WS_MAXIMIZEBOX | WS_MINIMIZEBOX,
0, 0,
CW_USEDEFAULT, CW_USEDEFAULT,
NULL, NULL, hInstance, NULL))) {
MessageBox(NULL, "Could not initialize window", "ERROR", MB_OK);
return ERROR;
}
ShowWindow(Uber, nShowCmd);
UpdateWindow(Uber);
while(GetMessage(&msg, Uber, 0, 0)) {
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
}
LRESULT CALLBACK MainWndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam) {
switch(message) {
case WM_DESTROY:
PostQuitMessage(0);
return 0;
default:
return DefWindowProc(hWnd, message, wParam, lParam);
}
}
