Question

我需要在托盘中显示主窗体对话框最小化的程序的输入对话框形式。目前我在桌面上显示了输入对话框，但是当这个表单第一次显示时它处于非活动状态。要激活此对话框，请执行以下操作：

BOOL CDialogExInput::OnInitDialog()
{
    CDialogEx::OnInitDialog();
    this->SetWindowPos(&this->wndTop,1000,1000,1000,1000,SWP_NOSIZE|SWP_NOMOVE);
    return true;
}

但是看起来这没有影响，因为即使对话框表单大小也没有改变。也许这不是正确的地方SetWindowPos？

UPT：

试图集中我的问题。让我们开始使用简单的基于对话框的应用程序。让我们运行它并停用（在任何其他窗口上单击鼠标）。我需要在计时器事件中激活我的对话框应用程序表单（在键盘输入焦点）。 SetWindowPos和SetFocus没有帮助。

OnInitDialog()正是您可以修改对话窗口的正确位置;当框架调用此函数时，对话框窗口已经存在但尚未可见。

如果您希望移动窗口并调整其大小，则在调用SWP_NOSIZE期间，您不能指定SWP_NOMOVE或SetWindowPos标记。

显示活动对话框表单甚至主程序窗口都不活动
