vsto:应用程序焦点

我也为此感到沮丧。你正在使用vsto应用程序中的对话框吗?如果是这样,我所做的是在关闭windows窗体/对话框时添加一个事件,以激活office应用程序,如下所示(例如word,因此excel中可能存在差异):

//... VSTO Startup Event
WindowsForm form = new WindowsForm();
form.FormClosed += new FormClosedEventHandler(form_FormClosed);
form.Show();


void form_FormClosed(object sender, FormClosedEventArgs e)
{
    this.Application.Activate();         
    this.Application.ActiveWindow.WindowState = Microsoft.Office.Interop.Word.WdWindowState.wdWindowStateNormal;

}

我发现这句话总是假的/是真的:

this.ActiveWindow.Active()

但这更有效(全局bool变量“appactive”用于跟踪活动窗口):

//... VSTO Startup Event    
this.Application.WindowDeactivate += new Microsoft.Office.Interop.Word.ApplicationEvents4_WindowDeactivateEventHandler(Application_WindowDeactivate);
this.Application.WindowActivate += new Microsoft.Office.Interop.Word.ApplicationEvents4_WindowActivateEventHandler(Application_WindowActivate);

    void Application_WindowActivate(Microsoft.Office.Interop.Word.Document Doc, Microsoft.Office.Interop.Word.Window Wn)
    {
        AppActive = true;
    }

    void Application_WindowDeactivate(Microsoft.Office.Interop.Word.Document Doc, Microsoft.Office.Interop.Word.Window Wn)
    {
        AppActive = false;
    }

this.ActiveWindow.Activate() 是激活窗口的方法。

this.ActiveWindow.Active 是告诉你窗口状态的属性。
