PDF Reader ActiveX Control

Waiting for your merge function xD

Hi,
Just ask !
Using Pdfium.dll to merge PDF files is not possible in VB6, as Fafalone stated.
However, I was largely inspired by Fafalone's TwinBasic code to create a 32-bit ActiveX DLL in TwinBasic, which can be referenced in VB6 and adds a function to merge PDF files.
You can find this DLL here: https://freeware.ordoconcept.net/dow...oPDFsMerge.zip

Best regards,
François

It's possible in VB6 with The trick's VBCDeclFix addin; his addin also allows creating the required CDecl callback function, you just add the CDecl keyword like the tB version, and change the Return syntax:

Private Function WriteBlock CDecl(ByVal pThis As LongPtr, ByVal pData As LongPtr, ByVal size As Long) As Long
        If hFileOut Then
            Dim cbRet As Long
            WriteBlock = WriteFile(hFileOut, ByVal pData, size, cbRet, vbNullPtr)
        End If
    End Function
