進出口試圖使C++ WINAPI程序時,它的唯一功能是繪製一個窗口,其中切換光標移動和點擊,但顯示窗口後,右側的按鈕,可以前的應用程序崩潰做某事。在窗口過程中,我只有WM_COMMAND,WM_DESTROY和默認返回DefWindowProc()的情況。 WinMain函數代碼:C++ APPCRASH USER32.dll中
WNDCLASSEX wcx;
int X, Y;
MSG msg;
RECT srect;
GetWindowRect(GetDesktopWindow(), &srect);
X = srect.right;
Y = srect.bottom;
wcx.cbSize = sizeof(WNDCLASSEX);
wcx.style = CS_HREDRAW | CS_VREDRAW | CS_DROPSHADOW;
wcx.lpfnWndProc = MainProc;
wcx.cbClsExtra = 0;
wcx.cbWndExtra = 0;
wcx.hInstance = hinst;
wcx.hIcon = 0;
wcx.hCursor = 0;
wcx.hbrBackground = (HBRUSH)(COLOR_WINDOW + 1);
wcx.lpszMenuName = 0;
wcx.lpszClassName = L"wcname";
wcx.hIconSm = 0;
if (!RegisterClassEx(&wcx)){
MessageBox(0, L".", L"RegisterClass failed", 0);
return 1;
}
hwnd = CreateWindowEx(
0,
L"wcname",
L"off",
WS_OVERLAPPEDWINDOW,
X/2 - 112,
Y/2 - 40,
224,
80,
0,
0,
hinst,
0
);
if (!hwnd){
MessageBox(0, L".", L"CreateWindow failed", 0);
return 1;
}
GetClientRect(hwnd, &srect);
X = srect.right;
Y = srect.bottom;
btn = CreateWindowEx(
0,
L"button",
L"Turn on",
WS_VISIBLE | WS_CHILD | BS_PUSHBUTTON,
0, 0,
X, Y,
hwnd,
(HMENU)BTN,
hinst,
0
);
ShowWindow(hwnd, nCmdShow);
UpdateWindow(hwnd);
while (GetMessage(0, hwnd, 0, 0)){
TranslateMessage(&msg);
DispatchMessage(&msg);
}
return 0;
的HWNDs是全局變量,BTN和主要的宏。
如果在調試器中運行,它會停在飛機墜毀的地方,讓你檢查變量的值,並檢查(並向上走)函數調用堆棧。做到這一點,找到(在你的代碼中)它崩潰的地方,並檢查值,看看你是否可以找出原因。 –
另外,以最大警告等級('/ W4')進行編譯。你可能會做一些明顯錯誤的編譯器可以檢測到的東西。 –
我用了Beep(300,300);作爲一個調試器,發現問題出在UpdateWindow(hwnd)之後。我試圖將嗶聲粘貼到GetMessage循環中,但是在嘟嘟聲之前應用程序崩潰可以發出聲音。我不知道如何處理這個問題 – user3392623
