OutLook and Windows Forms

[Mallikarjun]

I have created a commandBarbutton on a Commandbarpoup on a
Mailitem inspector. When I Click the button it should
open a Windows form Which has a textbox and Datagrid.
The form is opened for the first 5 times of button Click.
Later it does not.
Infact for the 6th time the Click event does not fire at
all.
Here is the code I have used.

private void CreatePopUp(CommandBar oStandardBar)
{

CmdBarPopup =(CommandBarPopup) oStandardBar.FindControl
(System.Reflection. Missing.Value,
System.Reflection.Missing.Value,"MailingPopup",System.
Reflection.Missing.Value,System.Reflection.Missing.Value);

if(CmdBarPopup == null)
{
// Add a pop-up menu to the command bar
object oMissing=System.Reflection.Missing.Value;
CmdBarPopup = (CommandBarPopup)
oStandardBar.Controls.Add(
MsoControlType.msoControlPopup,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value,
System.Reflection.Missing.Value,
true);
// Add a separator before the pop-up button.
CmdBarPopup.BeginGroup = true;
// Set the caption
CmdBarPopup.Caption = "Select Groups !!";
CmdBarPopup.Tag="MailingPopup";
// Add a pop-up.
CommandBarPopup oPopup = (CommandBarPopup)
CmdBarPopup.CommandBar.Controls.Add
(MsoControlType.msoControlPopup,
oMissing,
oMissing,
oMissing,
true);
oPopup.Caption="PIM-IT";
oPopup.Visible=true;
// Add a button to the pop-up
CommandBarButton oPopupButton = (CommandBarButton)
oPopup.CommandBar.Controls.Add
(MsoControlType.msoControlButton,oMissing,oMissing,oMissing
,true);
// Change the face ID and caption for the button.
oPopupButton.Style=MsoButtonStyle.msoButtonCaption;
oPopupButton.FaceId = 643;
oPopupButton.Caption = "Phone Details";
oPopupButton.Visible=true;
// Set up a delegate for the Click event.

dler oPopupButtonHandler = new
Microsoft.Office.Core._CommandBarButtonEvents_ClickEventHan
dler(oPopupButton_Click);
oPopupButton.Click += oPopupButtonHandler;

CmdBarPopup.OnAction = "<Mailinglist.Connect>";
// Show the command bar to the user.
CmdBarPopup.Visible = true;
}
