Inventor loses focus

[simonsson]

I've created a toolbar addin for Inventor (using C#). The toolbar contains a couple of buttons. If you click any button it will pop up a Form dialog with Inventor window set as parent. When closing some of the Form dialogs Inventor loses focus and another window pops up in front of Inventor. It could be Microsoft Explorer or any or the open windows in the background. I don't know what causes this problem. All Form dialogs are closed in the same way. I've tried both this.Close(); and this.Dispose();. Does anyone have any idea how to solve this?

Hi -

Can you show the code that you're using to establish the Inventor window as your dialog's parent?

// Win API
[DllImport("user32.dll")]
internal static extern int SetParent(IntPtr hWndChild, IntPtr hWndNewParent);


public MainForm()
{
InitializeComponent();

SetParent(this.Handle, (System.IntPtr)invApp.MainFrameHWND);

...

}

Are you using ShowDialog, or just Show()? If modeless, can you see if this works instead? If it's modal, you can use the same approach, but using ShowDialog.

...
NativeWindow hWnd = new NativeWindow();
hWnd.AssignHandle((IntPtr)invApp.MainFrameHWND);

MainForm yourForm = new MainForm();
yourForm.Show(hWnd);

This is a .NET issue (can't find the info again,
but it is out there). If you are seeing this, you will need to reset the focus
to the IV window in your code.

Thanks alot! I found this SetFocus method in the Win API that seems to work.
