Hello, this one is really ridiculous one. There are no problems at all with compilation but there is still a problem with functions.
I have no idea why does not the programme call my function but the code is right (I hope) if I copy the code straight to the WM_PAINT command it works normally. But if I try to call a function with the same content as before it suddenly fails to work...
Can you chceck please the code?
Code:
#include <windows.h>
LRESULT CALLBACK WndProc(HWND, UINT, WPARAM, LPARAM);
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance,
PSTR szCmdLine, int iCmdShow)
{
TCHAR szAppName[] = TEXT("Default window"); // Header
HWND hWnd;
MSG msg;
WNDCLASSEX wc;
wc.cbSize = sizeof(wc);
wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = WndProc;
wc.cbClsExtra = 0;
wc.cbWndExtra = 0;
wc.hInstance = hInstance;
wc.hIcon = LoadIcon(NULL, IDI_APPLICATION); // Ico
wc.hIconSm = NULL; // Ico_sm
wc.hCursor = (HCURSOR)LoadCursor(NULL, IDC_ARROW);
wc.hbrBackground = (HBRUSH)(COLOR_WINDOW+0); // Background
wc.lpszMenuName = NULL;
wc.lpszClassName = szAppName;
RegisterClassEx(&wc);
hWnd = CreateWindowEx(0,szAppName,
szAppName,
WS_OVERLAPPEDWINDOW,
CW_USEDEFAULT, // Margin from left
CW_USEDEFAULT, // Margin from top
CW_USEDEFAULT, // Widht
CW_USEDEFAULT, // Height
NULL,
NULL,
hInstance,NULL);
ShowWindow(hWnd, iCmdShow);
UpdateWindow(hWnd);
while(GetMessage(&msg, NULL, 0, 0))
{
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return msg.wParam;
}
void OnWM_PAINT()
{
HWND hWnd;
HDC hDC;
PAINTSTRUCT ps;
RECT rect;
GetClientRect(hWnd, &rect);
hDC = BeginPaint(hWnd, &ps);
DrawText(hDC, "Text text", -1, &rect, DT_SINGLELINE | DT_CENTER | DT_VCENTER);
EndPaint(hWnd, &ps);
}
LRESULT CALLBACK WndProc(HWND hWnd, UINT message, WPARAM wParam, LPARAM lParam)
{
switch(message)
{
case WM_PAINT:
OnWM_PAINT();
break;
case WM_DESTROY:
PostQuitMessage(0);
return 0;
}
return DefWindowProc(hWnd, message, wParam, lParam);
}
