Question

好吧所以我一直在努力学习c，我刚买了一本书（Charles Petzold编写Windows）我刚刚用代码编写了我的第一个程序：blocks。一切正常，但由于某种原因，它打开cmd窗口，如果它关闭程序。这是代码

#include <windows.h>
LRESULT CALLBACK WndProc (HWND, UINT, WPARAM, LPARAM);

int WINAPI WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, PSTR szCmdLine, int  
                   iCmdShow)
{
static TCHAR szAppName[] = TEXT ("HelloWin");
HWND         hwnd;
MSG          msg;
WNDCLASS     wndclass;

wndclass.style = CS_HREDRAW | CS_VREDRAW;
wndclass.lpfnWndProc = WndProc;
wndclass.cbClsExtra = 0;
wndclass.cbWndExtra = 0;
wndclass.hInstance = hInstance;
wndclass.hIcon = LoadIcon(NULL, IDI_APPLICATION);
wndclass.hCursor = LoadCursor(NULL, IDC_ARROW);
wndclass.hbrBackground = (HBRUSH) GetStockObject(WHITE_BRUSH);
wndclass.lpszMenuName = NULL;
wndclass.lpszClassName = szAppName;

if(!RegisterClass (&wndclass))
{
    MessageBox (NULL, TEXT ("This computer is stupid so im not gona work!"), szAppName, MB_ICONERROR);
    return 0;
}
hwnd = CreateWindow (szAppName, TEXT ("The program"), WS_OVERLAPPEDWINDOW, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT, CW_USEDEFAULT,
                     NULL, NULL, hInstance, NULL);
ShowWindow(hwnd, iCmdShow);
UpdateWindow(hwnd);

while (GetMessage(&msg, NULL, 0, 0))
{
    TranslateMessage(&msg);
    DispatchMessage(&msg);
}
return msg.wParam ;
}

LRESULT CALLBACK WndProc (HWND hwnd, UINT message, WPARAM wParam, LPARAM lParam )
{
HDC hdc;
PAINTSTRUCT ps;
RECT rect;

switch (message)
{
    case WM_CREATE:
         MessageBox(NULL, TEXT("a sound would play but i dont have the cd"),    
TEXT("sound"), 0);
         return 0;

    case WM_PAINT:
         hdc = BeginPaint (hwnd, &ps);
         GetClientRect(hwnd, &rect);
         DrawText (hdc, TEXT("sup, bra."), -1, &rect, DT_SINGLELINE | DT_CENTER
                           | DT_VCENTER);
         EndPaint (hwnd, &ps);
         return 0;

    case WM_DESTROY:
         PostQuitMessage(0);
         return 0;
}
return DefWindowProc(hwnd, message, wParam, lParam);
}

链接时，您的目标是CONSOLE子系统。执行此操作时，结果是一个可执行文件，在启动时自动拥有控制台。

相反，您需要定位GUI子系统。 GUI子系统可执行文件在启动时不会自动为其提供控制台窗口。

您需要在IDE或链接命令行中找到指定子系统的选项，并进行适当的更改。

cmd在不应该打开时打开
