将非模态表单重新映射到现有应用程序

Reparent non-modal form to existing application(将非模态表单重新映射到现有应用程序)

问题描述

我希望能够在现有应用程序中显示非模态表单.目前我可以这样做:

I would like to be able to show a non-modal form in an already existing application. At the moment I can do something like:

myform.ShowDialog(handleToApp);

但这将创建一个以应用程序为父对象的模态表单，而我真正要寻找的不是模态表单，因此当表单失去焦点时，它不会破坏控制流程并纠缠用户不要关闭.

but that will create a modal form parented to the application and what I'm really looking for something that isn't modal so when the form loses focus it won't break the flow of control and pester the user about not being closed.

有谁知道我如何或是否可以做我正在寻找的事情?

Does anyone know how or if I can do what I'm looking for?

推荐答案

我找到了我要找的东西，你必须创建一个如下所示的类:

I found what I was looking for, you have to make a class which looks like this:

public class MapinfoWindowHandle : System.Windows.Forms.IWin32Window
    {
        private IntPtr handle;
        public MapinfoWindowHandle(IntPtr hWnd)
        {
            handle = hWnd;
        }

        #region IWin32Window Members

        IntPtr System.Windows.Forms.IWin32Window.Handle
        {
            get { return handle; }
        }

        #endregion
    }

然后你可以这样做:

IntPtr windowhandle = new IntPtr(hWnd);
MyForm.Show(new MapinfoWindowHandle(windowhandle));
