Win 7 x64
I am registering
regsvr32 "C:\Program Files (x86)\Debenu\PDF Library\ActiveX\DebenuPDFLibrary64AX1212.dll"
I use VB6
Private Sub btnHelloWorld_Click()
Dim ClassName
Dim LicenseKey
Dim FileName
ClassName = "DebenuPDFLibrary64AX1212.PDFLibrary"
LicenseKey = "..." 'SET YOUR LICENSE KEY HERE...
FileName = "c:\hello-world.pdf"
Dim QP
Dim Result
Set QP = CreateObject(ClassName)
Result = QP.UnlockKey(LicenseKey)
If Result = 1 Then
MsgBox "Library version: " + QP.LibraryVersion
MsgBox (QP.LicenseInfo)
Call QP.DrawText(100, 500, "Hello world from Visual Basic 6.0.")
If QP.SaveToFile(FileName) = 1 Then
MsgBox "File " + FileName + " written successfully."
Else
MsgBox "Error, file could not be written."
End If
Else
MsgBox "Invalid license key. Please set your license key by editing this file."
End If
End Sub
The library does not work.
Error to string:
Set QP = CreateObject(ClassName)
Activex component can't create object
Error 429
If you use the library x32, then there is no problem.
How to use x64 to VB6?

Hi Dimitry,
vb6 is a 32-bit-ide not working with 64-bit-dlls in a proper way.
You can work with vb6 and the 32-bit-dll on a windows-64-bit-system.
In this case the 32-bit-dll have to be inserted into the syswow64-path.
Cheers and welcome here,

Thanks for the answer Ingo.
I think it's wrong.
By connecting the Reference - I get all the methods and properties of the library.
But at start-up, an error occurs at the input, I think that this is not related to the bit depth.
Then another question:
How to connect using the GetObject?
Set myobj = GetObject ("", "ProjectName.ClassName")

It should be clear that it's impossible to create a 64-bit-application with vb6 (a 32-bit-ide). So it won't make any sense to link this ide to a 64-bit-dll.
If we forget your vb6 the common correct answer will be:
A 64-bit-dll on a 64-bit-windows-system should always be in the system32-path.
