Hi All,

I have created outlook addin for outlook 2003 in vsto-2008. When I have
tried to allow property 'allowDrag' to textbox it gives runtime
exception "dragdrop registration did not succeed". I have searched on
net, got suggestion to use threading.

Thread t = new Thread(new ThreadStart(ShowForm));
t.SetApartmentState(ApartmentState.STA);
t.Start();

public void ShowForm()
{

form.ShowDialog();
form.Dispose();
}

Drag problem solved using thread but it give other problem in my
application as follows
a) When I right click on context menu then form disappear.
b) Some time application hangs...

Can I solve this problem without using thread? Because handling thread
will almost change my design.

Regards,
Nit
