Re: help with rasterevent

Hello,

To enable firing the RasterEvent event, you must set the value of the EnableRasterEvent property to TRUE before start prining the print job.
Please check the following code:
+-------+
Dim WithEvents ePrintEvents As ePrint

Private Sub ePrintEvents_RasterEvent(ByVal PrinterName As String, ByVal PrnImage As stdole.IPictureDisp)
   Picture1.Picture = PrnImage
End Sub

Private Sub menu_EnableRasterEvent_Click()
   Set ePrintEvents = New ePrint
   ePrintEvents.UnlockSupport SUPPORT_OEM, OEM_KEY

   ePrintEvents.EnableRasterEvent ("LEADTOOLS ePrint 5") = True
End Sub
+-------+

Thanks,

Re: help with rasterevent - urgent

hello,

I 've tried doing that earlier. But Visual Studio 2005 is not recognising stdole.IPictureDisp. It is giving an error saying that the type for stdole.IPictureDisp is not defined. So I tried using system.Drawing.Image for this event , it doesnt seem to work. Could anyone plz look into this..

Thank you,
reddy

Re: help with rasterevent - urgent

Hello,

Can you please send me a small working project (not your full application) the shows the problem, so that I can debug the code and maybe fix this issue?

Also, what is the LEADTOOLS ePrint product id that you use?
You can find LEADTOOLS ePrint product ID on the "About" tab on your LEADTOOLS ePrint 5.0 driver properties dialog.

Thanks,
