我有一个Outlook 2013 VSTO加载项。我想居中创建的saveFileDialog。为此,您需要向其传递父对象的Window
对象。我不确定IWin32Window
和Window
是否相同,但这就是我所拥有的。
public IWin32Window getWindowHandle()
{
dynamic activeWindow = Globals.ThisAddIn.Application.ActiveWindow();
IntPtr outlookHwnd = new OfficeWin32Window(activeWindow).Handle;
IWin32Window win = Control.FromHandle(outlookHwnd);
return win;
}
SaveFileDialog.ShowDialog(Window)
方法带有一个窗口。我可以通过IWin32Window
吗?除了Window
之外,是否有其他方法可以从处理程序中获取Control.FromHandle
对象?任何批评都将受到欢迎。
谢谢
编辑:
哦,还有那个函数的帮助类:
public class OfficeWin32Window : IWin32Window
{
[DllImport("user32")]
public static extern IntPtr FindWindow(string lpClassName, string lpWindowName);
IntPtr _windowHandle = IntPtr.Zero;
public IntPtr Handle
{
get { return _windowHandle; }
}
public OfficeWin32Window(object windowObject)
{
string caption = windowObject.GetType().InvokeMember("Caption", System.Reflection.BindingFlags.GetProperty, null, windowObject, null).ToString();
// try to get the HWND ptr from the windowObject / could be an Inspector window or an explorer window
_windowHandle = FindWindow("rctrl_renwnd32\0", caption);
}
}
给出了这段代码,所以我对此有一个疑问:
FindWindow("rctrl_renwnd32\0", caption)
做什么?我一点都不明白。特别是“ rctrl_renwnd32 \ 0”部分。编辑:
IOleWindow类的新功能:
public IOleWindow getWindowHandle()
{
dynamic activeWindow = Globals.ThisAddIn.Application.ActiveWindow();
IOleWindow win = activeWindow as IOleWindow;
window = win.GetWindow();
//IntPtr outlookHwnd = new OfficeWin32Window(activeWindow).Handle;
//IWin32Window wind = Control.FromHandle(outlookHwnd);
return window;
}
编辑2:
更新后的逻辑,我删除了该函数,并将其添加到需要的位置:
Inspector currentObject = Globals.ThisAddIn.Application.ActiveInspector();
var winh = currentObject as IOleWindow;
IntPtr win = winh.GetWindow();
编辑3:
重组:
Inspector currentObject = Globals.ThisAddIn.Application.ActiveInspector();
var winh = currentObject as IOleWindow;
IntPtr win;
winh.GetWindow(out win);
最佳答案
FindWindow方法检索顶级窗口的句柄,该窗口的类名和窗口名与指定的字符串匹配。第一个参数指定窗口类名称。第二个参数是窗口名称(窗口标题)。如果此参数为NULL,则所有窗口名称均匹配。
无需使用FindWindow函数,您需要将资源管理器或Inspector窗口强制转换为IOleWindow界面,并使用GetWindow方法来获取窗口句柄。

IWin32Window接口的实例用于为Show或ShowDialog方法指定父窗口句柄。
