Also is there any way i can check that an instance of application is already running thanks

If
Ubound(Diagnostics.Process.GetProcessesByName(Diagnostics.Process.GetCurrentProcess.ProcessName))

0 Then
Return True
Else
Return False
End If
End Function

in VB6
app. PrevInstance

Hi
Yes u can do that
Make a module and add a sub as Sub Main
In the project properties, in Startup Object u will have that “Sub Main”
Select it, the exe will first run the Sub Main of that module
The way u r going around doesnt solves your purpose
Try thru module Sub Main
I am already using it in my live project

Hi
Well…the functionality that u r asking for can be handled like this

  1. Make a module
  2. Make the module as the startup
  3. Apply what ever logics u want to apply before starting the main form
  4. Call the Application.Run(New
