我有一个 Outlook 2013 VSTO 插件。我想将我创建的 saveFileDialog 居中。为此,您需要将父级的 Window
对象传递给它。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)
方法需要一个窗口。我可以将 IWin32Window
传递给它吗?有没有办法从 Control.FromHandle
以外的处理程序获取 Window
对象?
欢迎任何批评。
谢谢

哦,还有那个函数的辅助类:
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);
}
}
我得到了这段代码,所以我有一个关于它的附带问题:FindWindow("rctrl_renwnd32\0", caption)
做什么?我完全不明白。特别是“rctrl_renwnd32\0”部分。

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:
我更新的逻辑,我删除了函数并将其添加到我需要句柄的地方:
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,其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。第二个参数是窗口名称(窗口的标题)。如果此参数为 NULL,则所有窗口名称匹配。
您需要将资源管理器或检查器窗口转换为 IOleWindow,而不是使用 FindWindow 函数界面并使用GetWindow获取窗口句柄的方法。

IWin32Window 接口(interface)的实例用于指定 Show 或 ShowDialog 方法的父窗口句柄。
