I have one project that is working with QuickPDF without issue. When i go to create another It seems to fail and i I cannot seem to figure out why.

I have imported the: QuickPDFDLL0813.dll and QuickPDFDLL0813.vb files into the project.

Set the Imports: Imports BLINK_DOC_MANAGMENT.QuickPDFDLL0813

Then I run the following and it says "invalid licence key"

Dim QP As PDFLibrary

Dim LicenseKey

Dim Result

QP = New PDFLibrary("QuickPDFDLL0813.dll")

LicenseKey = "je5e3798XXXXXXXXXXXXXpb6y"

Result = QP.UnlockKey(LicenseKey)

If Result = 1 Then

QP.SetOrigin(1)

QP.DrawText(100, 100, "Hello Visual Basic! This text has been drawn using the DrawText function.")

QP.SaveToFile("Hello_World.pdf")

Else

MsgBox("- Invalid license key -")

End If

Is there something else that I have missed?

Hello dptulk,

a dim state without type create an object or a variant, which could not be terminated by the right character for a string.

did you try to prototype the key as string?
which VS are you using?

I set the key as a string and it still does not work. I am using VS 2010 Pro.

This just doesn't make any sense. My other project works just fine but I have tried several others and none of them will work.

Here is the current version. I hope that someone has some insight into this:

Imports QuickPDFBase.QuickPDFDLL0813

Imports System.IO

Public Class QuickPDFTest

Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles Button1.Click

Dim QP As PDFLibrary

Dim LicenseKey As String

Dim Result As Boolean

QP = New PDFLibrary("QuickPDFDLL0813.dll")

LicenseKey = "XXXXXXXXXXXXXXXXXXXXX"

Result = QP.UnlockKey(LicenseKey)

If Result = 1 Then

QP.SetOrigin(1)

QP.DrawText(100, 100, "Hello Visual Basic! This text has been drawn using the DrawText function.")

QP.SaveToFile("Hello_World.pdf")

Else

MsgBox("sh*t!")

End If

End Sub

End Class

It's roughly the same code i used with few differences

+ result is an integer or a long not a boolean
+ i'm using 7.x version of the dll
+ when i call the new library, i point directly to the full dll path to avoid misinterpretation by he compiler

You may need to set your Platform Target to x86 to force it to create a 32 bit EXE. If it is currently set to Any CPU then it could be creating a 64 bit EXE which is then failing to load the 32 bit DLL.

You could run a quick test by changing the code to the following

QP = New PDFLibrary("QuickPDF64DLL0813.dll")

You would need to make sure the 64 bit DLL is in the same directory as your EXE file.

The next step could be add the following so that it can run either 32 or 64 bit mode automatically.

if (IntPtr.Size == 4)

QP = New PDFLibrary("QuickPDFDLL0813.dll")

else

QP = New PDFLibrary("QuickPDF64DLL0813.dll")

Thanks Andrew. It was not the 64 bit issue. Not sure what it was really. I ended up creating an empty project and getting it to work and then moving all of my code from my other one into the new one.
