Hi,

When i execute my Vb6 application (with F5 in Vb) thant run a report , that's ok.
when i run application which i've installed on another Pc, report.action = 1 shutdown
here my sample code

Public Sub ConfEtActiveReport(ByRef rpt, Optional vmintNbrCopies As Integer)

On Error GoTo ConfEtActiveReport

' Alimentation du report avec les informations
rpt.PrinterName = vgstrNomImpr
rpt.PrinterPort = vgstrNomPort
rpt.PrinterDriver = vgstrNomDriver
rpt.CopiesToPrinter = IIf(Len(vmintNbrCopies) = 0, 1, vmintNbrCopies)

' Réinitialisation des variables
vgstrNomImpr = ""
vgstrNomPort = ""
vgstrNomDriver = ""

' Lancement de l'état
rpt.Action = 1
'rpt.PageZoom (75)

Exit Sub


ConfEtActiveReport:

Aff_MesBox CRITIQUE, "ConfEtActiveReport : " & Err.Description

End Sub

where rpt is an report object pass by reference with propety connect = UID=userid;PWD=passwd;DSQ=datasource
these 3 param is ok when i connect my report in designer

vgstrNomImpr, vgstrNomPort, vgstrNomDriver are 3 variables may be null
