UserControl hosted in browser problem.

[AnNguyen]

Hello everyone.

I created 2 windows control library UC1, UC2. They are both hosted in browser (IE). It's Ok to run each of them separately by typing http//localhost/UC1.html or http//localhost/UC2.html. I wonder is it posible to launch UC2 from UC1, let say i put a button on the control UC1 and when user click this button, it will launch the UC2 the same way as you type the 2nd link in the Ie address bar.
I google on this problem but can not find anything. any help would be much appreciated.

Thanks.

Thank you chmohan , unfortunately it didnt work.

Here my code

private void btnlaunchIE(object sender, System.EventArgs e)
{
try
{
System.Diagnostics.Process.Start("IExplorer.exe","

http://www.yahoo.com");

}
catch (Exception e1)
{
txtRemarks.Text = e1.ToString();
}
}

and txtRemarks show this error

System.Security.SecurityException: Request for the permission of type
System.Security.Permissions.SecurityPermission,

I found a solution ( at least for me) and here what i did

1. go to Controlpanel/admintools/
2. Open ms.net framework config
3. expand Machine/codegroup/all_codes/
4. right click LocalIntranet_Zone then click properties.
5. in membership condition Tab set the first combobox to URL and type

http://localhost/*

or your webserver/*
6. in Permission Set TAB set the permision to fultrust.
7. click OK to save the change and restart the web server. And Voila it works.

Hope this will help
