我有个问题。我希望在我的程序(跟随代码)中有 2 个窗口:控制台和空表单来输出图形。并从我的 func main 发送消息以形成绘制形状。向控制台输入数据。但是 func SendMessage() 不起作用。怎么了?
int main()
{
char szClassName[] = "CG_WAPI_Template";
HWND hWnd = GetConsoleWindow();
HINSTANCE hInstance = NULL;
MSG lpMsg;
if(!AllocConsole())
MessageBox(NULL, "Failed to create the console!", "Ошибка", MB_ICONEXCLAMATION|MB_OK);
void *h_inc = GetStdHandle(STD_INPUT_HANDLE);
void *h_out = GetStdHandle(STD_OUTPUT_HANDLE);
WNDCLASS wc;
/*wc.style = CS_HREDRAW | CS_VREDRAW;
wc.lpfnWndProc = WndProc;
...
*/
if(!RegisterClass(&wc))
{MessageBox(NULL, "Не могу зарегистрировать класс окна!", "Ошибка", MB_OK);
return 0;
}
hWnd = CreateWindow(...);
ShowWindow(hWnd, SW_MAXIMIZE);
UpdateWindow(hWnd);
char buf[2];
unsigned long lengh;
ReadConsole(h_inc,buf,1,&lengh,NULL);
SendMessage(hWnd, WM_USER+2, 0, 0);
if(GetMessage(&lpMsg, NULL, 0, 0))
{
TranslateMessage(&lpMsg);
DispatchMessage(&lpMsg);
}
ReadConsole(h_inc,buf,1,&lengh,NULL);
if (!FreeConsole())
MessageBox(NULL, "Could not free the console!", "Ошибка", MB_OK);
return 0;
}
谢谢你。
