我是新來學習使用C++創建一個Win32程序,但是,當我按照一本書的指示,試圖製作我的第一個程序,我遇到以下問題需要幫助的基本Windows的C
#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;
deafult:
return DefWindowProc(hwnd, msg, wParam, lParam);
}
return 0;
}
int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nCmdShow)
{
WNDCLASSEX wc;
HWND hwnd;
MSG Msg;
//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(GetMessage(&Msg, NULL, 0, 0) > 0)
{
TranslateMessage(&Msg);
DispatchMessage(&Msg);
}
return Msg.wParam;
}
,但它一直返回「窗口創建失敗!」,我不知道它有什麼問題,並且我做了很多校對。請幫幫我!
查看'CreateWindowEx'的文檔,如果調用失敗,您會看到一個有用的提示,使用'GetLastError'獲取更多信息。習慣使用該功能並告訴我們錯誤代碼。 – chris
