Koda kārtība failā nebūt nenorāda tā izpildes kārtību:
| Code: | void a() {
// ...
}
void b() {
// ...
}
int main() {
b(); // izpilda b() fju pirms a() fjas
a();

Tev manupraat vajadzeetu dariit sekojosji:
case WM_CLOSE:
if (IsWindow(window->hWnd)) DestroyWindow(window->hWnd);
break;
jo ja tu nospied X tad MS Windows logu automaatiski Destroy'o.

| Code: |
LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam){
sWindow* window = (sWindow*)(GetWindowLong(hWnd,GWL_USERDATA));
switch(uMsg){
/* case WM_CLOSE:
DestroyWindow(window->hWnd);
break;*/
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, uMsg, wParam, lParam);
}
return 0;
}

Shitas tev nemuuzham nestraadaas. Palasi MSDN helpaa ko dara funkcija GetWindowLong().
"If SetWindowLong has not been called previously, GetWindowLong returns zero for values in the extra window or class memory."
Kaapeec gan tev vajag window->hWnd ja noraade uz logu jau dota WndProc() parametros???
Shitam vajadzeetu straadaat ,be nekaadiem GetWindowLong():
| Code: |
LRESULT CALLBACK WndProc(HWND hWnd, UINT uMsg, WPARAM wParam, LPARAM lParam){
switch(uMsg){
case WM_CLOSE:
if(hWnd)
DestroyWindow(hWnd);
break;
case WM_DESTROY:
PostQuitMessage(0);
break;
default:
return DefWindowProc(hWnd, uMsg, wParam, lParam);
}
return 0;
}

Liels jums paldies ieboreejaat arii manaas smadzenees saprašanu par vairākām tēmām(jau).
Man to vajadzeeja dariit jo ir doma, ka struktuurā Windows atradiisies ne tikai tas, bet taustiņu stāvoklis u.t.t.
Bet ja es pēc Create Window Pārbaudu vai hWnd nav NULL, tad jau es noteikti zinu, ka logs ir izveidots. Tas atkal nozīmē, ka var iztikt bez WM_CREATE un CREATESTRUCT* vai tomēr es kļūdos  |

Var iztikt bez WM_CREATE, var iztikt arii bez WM_CLOSE un WM_DESTROY. Tas viss ir domaats lai papildinātu logu ar dazhaadaam iespeejaam, par visu minimaalo kas nepiecieshams, lai logs paraadiitos paruupeejas DefWindowProc();
