在wm_command 中回應按鈕事件，程式會卡死，按下按鈕可以彈出訊息框，但是之后程式就沒了反映了，代碼如下：
BOOL CALLBACK DlgMain(HWND hwndDlg, UINT uMsg, WPARAM wParam, LPARAM lParam)
{
switch(uMsg)
{
case WM_INITDIALOG:
{
CreateWindowEx(NULL, __TEXT("BUTTON"), __TEXT("Update"),WS_VISIBLE | WS_CHILD , rcDlg.right-100, 0, 50, 20, hwndDlg, NULL, hInst,NULL);
}
return TRUE;
break;
case WM_CLOSE:
{
EndDialog(hwndDlg, 0);
}
return TRUE;
break;
case WM_COMMAND:
{
switch(LOWORD(wParam))
{
case IDGO1:
MessageBox(hwndDlg,__TEXT("xx"),__TEXT("yy"),MB_OK);
break;
}
}
return TRUE;
break;
}
return FALSE;
}
int APIENTRY WinMain(HINSTANCE hInstance, HINSTANCE hPrevInstance, LPSTR lpCmdLine, int nShowCmd)
{
hInst=hInstance;
InitCommonControls();
return DialogBox(hInst, MAKEINTRESOURCE(DLG_MAIN), NULL, (DLGPROC)DlgMain);
}

不是這個ID問題，點擊按鈕后messagebox可以彈出來，但是沒多久界面就卡死了，上windbg附加后看堆疊資訊，發現：0:000> k

一直在USER32里轉悠，貌似訊息回圈被卡死了：
