Go into the articles section and look for articles in the C# COM Interop section. There are two articles that talk about interaction betweeen IE and a Windows Form application including my article. You probably want to have the IE code fire an event back into the WinForm code which would then cause the WinForm code to open a new window of itself.
is your export form should be modal? If not, you can make your export form as class member and construct it in your main form contstructor and at View_Click(..) you can write only exportForm.Show(); Hope this help Hesham
