In VBexe - CrystalReport hangs 1st time in client pc, 2nd time shows data correctly

Hai,

I written the porblem and I don't know where to attach the picture files of the Report file so i attach only my Picture of Form with this Post. Without finishing this problem I can't implement this Project. As you know the database here is MsSql, developing the front end in VB, I am using the Crystal Report 8.5 tool to show the Reports from vB.
The Report Hangs for the first time it shows only the blank screen, then the user need to close the Application Manually (i.e) through EndTask program. All our clients are using WinXP.
Where as the Report shows for the Second time and further.
Here the Form picture is attached with this Mail. The project is compiled in the machine where it is devoloped [Advanced 2000 Server] and also tested by changing the project to WinNt Server and installed VB6 there and compile the porject from there. Win2000 AdvancedServer or WinNT both are servers. While runnging the VB it shows the Report without any interuption, where as when i am running from the client system it hangs for the First time, some times hangs for first 2 times (Usually I compile the project and run the Setup file in the Client machine and then create the Shortcut of the exe for them)

The Print Command Button in the Form contains the following Code.

Private Sub Printe_Click()
On Error Resume Next
If optProduct.Value = True Then
Call optPpwise
ElseIf optItem.Value = True Then
Call optPitemwise
ElseIf optInvoice.Value = True Then
Call optInvoice
ElseIf optSlsmanwise.Value = True Then
Call optPsalessum
ElseIf optcsum.Value = True Then
Call optPcsum
ElseIf optPcustName.Value = True Then
Call Pcustname
ElseIf optCustdetail.Value = True Then
Call optPcustdetail
ElseIf optCust.Value = True Then
Call optPcstwise
ElseIf optcsumvalue.Value = True Then
Call PCsumListbyValue
Else
MsgBox "Choose Option !", vbExclamation, "Option - Missing"
End If
End Sub

If the User Clicks the Invoicewise Option Button and press PrintButton then the following code will fire.

Private Function optInvoice()
CrystalReport1.GroupSelectionFormula = ""
Dim i As Integer
Dim pfdt As Date
Dim ptdt As Date
Dim strsf As String

For i = 1 To 25
CrystalReport1.Formulas(i) = ""
Next i
pfdt = txtpfrom.Text
ptdt = txtpto.Text

If Len(cmbPprod.Text) <= 0 Or cmbPprod.Text = "All" Then
CrystalReport1.ReportFileName = App.Path & "\invoicewiseitemwgt.rpt"
strsf = "{ST030100.ST03015} in Date(" & _
Format(pfdt, "YYYY,M,D") & ") to Date(" & _
Format(ptdt, "YYYY,M,D") & ")"
CrystalReport1.ReplaceSelectionFormula (strsf)
CrystalReport1.Formulas(1) = "fdt='" & Format(pfdt, "DD/MM/YYYY") & "'"
CrystalReport1.Formulas(4) = "tdt='" & Format(ptdt, "DD/MM/YYYY") & "'"
CrystalReport1.DiscardSavedData = True
CrystalReport1.PrintReport
Else
CrystalReport1.ReportFileName = App.Path & "\invoicewiseitem.rpt"
strsf = "{ST030100.ST03015} in Date(" & _
Format(pfdt, "YYYY,M,D") & ") to Date(" & _
Format(ptdt, "YYYY,M,D") & ")"
CrystalReport1.ReplaceSelectionFormula (strsf)
CrystalReport1.GroupSelectionFormula = "{ST030100.ST03018}='" & cmbPprod.Text & "'"
CrystalReport1.Formulas(1) = "fdt='" & Format(pfdt, "DD/MM/YYYY") & "'"
CrystalReport1.Formulas(4) = "tdt='" & Format(ptdt, "DD/MM/YYYY") & "'"
CrystalReport1.DiscardSavedData = True
CrystalReport1.PrintReport
End If
End Function

As below in the FormLoad event I am connecting Crstal Report to Database
Private Sub Form_Load()
CrystalReport1.Connect = "DSN=scalaDB;UID=scala;PWD=scala"
End Sub

Thank you very much,
Chock.
