GetPageText crashes my app when used with DLL

Message Topic Search Topic Options Post Reply Create New Topic Printable Version Translate Topic

   Hello, 

i have integrated Quickpdf in my vb.net application to extract text from pdf-files.
It works fine when i use the ActiveX-control, but when i use the DLL version, it completely crashes my application as soon as i execute the GetPagetext function. 
i am using the resource code from the QuickPDFDLL0721.vb file in the sample project.

I would rather use the dll-version because it doesn't have to be registered. 
Registering the activex-dll is a pain on vista and later machines when i distribute an update to my users.

This is my code : 

Dim qp As PDFLibrary

Dim LicenseKey

Dim Result

' Update path to DLL if necessary

'QP = New QuickPDFAX0721.PDFLibrary  -- This is the Activex code, which works

qp = New PDFLibrary("C:\Program Files\Quick PDF Library\DLL\QuickPDFDLL0721.DLL")

' Insert your trial or commercial license key here

LicenseKey = "my_licence_key"

Result = QP.UnlockKey(LicenseKey)
If Result = 1 Then

QP.LoadFromFile(vanbestand)
QP.SelectPage(1)
pdfinhoud = QP.GetPageText(0)
Else

MsgBox("- Invalid license key -")

End If

QP = Nothing
