use Xchange SDK in service

[chavas]

Hi,

We would like to use PDF-Xchange SDK in a service to optimize PDFs. I have the following code for that-
Dim fsInst As PDFXEdit.IAFS_Inst = CType(Inst.GetExtension("AFS"), PDFXEdit.IAFS_Inst)
Dim impPath As PDFXEdit.IAFS_Name = fsInst.DefaultFileSys.StringToName(outputpath)
'' //We save it on disk
doc.CoreDoc.WriteTo(impPath)
Dim pxcInst As PDFXEdit.IPXC_Inst = CType(Inst.GetExtension("PXC"), PDFXEdit.IPXC_Inst)
Dim resDoc As PDFXEdit.IPXC_Document = pxcInst.OpenDocumentFrom(impPath, Nothing)
'' //Then pass it to the optimization operation
input.Add().v = resDoc
Dim options As PDFXEdit.ICabNode = op.Params.Root("Options")
Dim images As PDFXEdit.ICabNode = options("Images")
images("Enabled").v = True
images("ReducedOnly").v = True
Dim comp As PDFXEdit.ICabNode = images("Comp")
comp("Color.JPEGQuality").v = 0
comp("Grayscale.JPEGQuality").v = 0
op.Do()
'' //And save the optimized document again to the same file
resDoc.WriteTo(impPath)
I would like to know if it is possible to use the control without keeping an instance of the control on the window and what steps should be taken to ensure no memory leak. Our service would be processing PDF files in a loop. We would load the plugin (PDFOptimizer.pvp) when the service starts.

Hello Charu,

Well the steps would be to Init the IPXV_Inst once when service starts and Shutdown it when the service is being destroyed. To avoid leaks - use C++ - there you would manage all of the memory by yourself and you can guarantee that no leaks are being left.

Cheers,
