What do you mean by have progress ? Do you mean a progress bar. What are you doing in the load event of that form. What causes it to be slow ? A bit more information is needed.

This depends on the amount of operations u are doing in the page_load of the form. If u have a datagrid for example then u might have to use paging to populate the data ( if the data is huge).

Do tell me what are the kind of controls u have in the form the operations u are performing at page_load

Hi LearnITvn,

Still a bit more information is needed, What are you doing in the load event (calculations, loading data from a database etc..)

If you could post your form load event, we can  see what is happening?

After showing the form call the refresh method of the form.

f.Show()
f.Refresh()

When the progress bar is activated on another form, it means that u have delegated control to the progress form. The very purpose of having a progress bar means that u are having some background operations happening like - Retriving data or updating data or loading a form.

What operation do u want to do on your main form when progress form is activated?

Here is the Module that runs both forms

'This is the progress form
' Form2
I just added a ProgressBar and change its modifiers property to Public

'This is the main form
Public Class Form1
    Public ProgressForm As Form2

    'Instead of a timer you would have your code when opening the database a other stuff
    Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
       
        'I am using the reference to ProgressForm, since this have an instance of the Progress form
        With ProgressForm.ProgressBar1
            .Value += 1
            If .Value = .Maximum - 1 Then
                Timer1.Enabled = False
                ProgressForm.Close()
            End If
        End With
       
    End Sub    
End Class


Module Module1
    Public Sub main()
        Dim frmMainForm As New Form1
        Dim frmProgress As New Form2
        frmMainForm.ProgressForm = frmProgress

        frmProgress.TopMost = True 'This will make the progress form be always on top

        frmProgress.Show()
        Application.Run(frmMainForm)

    End Sub
End Module
