[swetham]

I have created an outlook application and the code is,

Private WithEvents btn1 As Office.CommandBarButton
Private Sub ThisAddIn_Startup(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Startup

Dim explorer As Outlook.Explorer = Me.Application.ActiveExplorer()

If explorer IsNot Nothing Then

Dim bar As Office.CommandBar = explorer.CommandBars.Add("HOCHTIEF", Temporary:=True)

bar.Visible = True
btn1 = bar.Controls.Add(Office.MsoControlType.msoControlButton, Temporary:=True)

btn1.Caption = "HOCHTIEF"

btn1.Tag = "myOutlookAddin1.btn1"

btn1.Style = Office.MsoButtonStyle.msoButtonCaption

End If
End Sub

Private Sub Btn1_Click(ByVal ctrl As Office.CommandBarButton, ByRef cancelDefault As Boolean) Handles btn1.Click
msgbox ("Button clicked")
End Sub


Message box is getting displayed perfectly but if i want to run an exe in button click i am not able to write process.start() method. CAn anyone please help me out?
