hello,
I'm making a copy of a PDF Image to a new Document in VB .NET using the DLL library version in a Windows Service application
i'm opening the document as string (byte array) in a method
Private WithEvents _qp As PDFLibrary
.
.
.
public sub new()
_qp = New PDFLibrary(dllPath)
_qp.UnlockKey("XXXXXXX")
end sub
private function Func1 (doc as byte(), Optional ByVal password As String = "") as memorystream
Dim docId As Integer
docId = _qp.LoadFromString(inPdf, password)
Return Func2(docId, password)
End function
private function Func2(docId as integer,password as string) as memorystream
dim ret as integer
dim newDoc as integer = _qp.NewDocument()
ret = _qp.SelectDocument(DocId) ' <<<<========== THIS RETURN 0 always in the service but runs correctly in a windows form application
_
end function
What am i doing bad?
Thanks in advance
best regards
PD: i'm sorry for my english

What do the other functions return if it's running as a service?
I think they give an error, too.
Where's the dll? It should be on the same machine, path where your app is working.
I think that's the problem?
Cheers and welcome here,
Ingo

Hello Ingo
If i execute "ret = SelectDocument(DocId)" and "imagesFoundId = _qp.FindImages" before open the new document this runs correctly.
The problems appears when i have two documents opened.
I've debugged the service to check the path to the DLL and this is correct
Thanks in advance

I've seen my error, the DocId is invalid.
I set the value from LoadFromString function, now i use the SelectedDocument function after open the document.
Thanks for your help Ingo
