这是完整的代码，当我尝试编译时，hWnd 总是返回 false...我什至尝试从工作程序中复制代码但它没有工作...这是怎么回事？之前一直有效...

你在 WndProc 函数中扭曲/交叉你的 wParam 和 lParam -

LRESULT WINAPI WndProc(HWND hWnd,UINT msg,WPARAM lParam,LPARAM wParam) 
{
    return DefWindowProc(hWnd,msg,wParam,lParam);
}

LRESULT WINAPI WndProc(HWND hWnd,UINT msg,WPARAM lParam,LPARAM wParam) {
    return DefWindowProc(hWnd,msg,wParam,lParam);
}

我认为这没有帮助。

LRESULT WINAPI WndProc(HWND hWnd,UINT msg,WPARAM lParam,LPARAM wParam) //check your parameter names!!!!!!!!!!!!!!!!!!!!!!!
{
    return DefWindowProc(hWnd,msg,wParam,lParam);
}
