Hi,

how to apply code to decode Base64 Zip File in Blob Field and extract the File from Zip Folder in NAV2009Classic Client. Now with existing code it works fine when attachment in XML file is PDF, it is properly encoded and write the file details in Blob field and read (decode) in Navision. But when it is Zip File, it throws error while decoding like below.

    Base64 decoding:
    Automation = 'CG Request Client'.Base64
    obtain it installing commerce gateway from nav installation

    IF ISCLEAR(XMLNode) THEN
    ERROR(Text001);
    IF ISCLEAR(Base64) THEN
    CREATE(Base64);
    Bestand.CREATETEMPFILE;
    FileName := Bestand.NAME;
    Bestand.CLOSE;
    Base64.Decode(FileName,XMLNode);
    CLEAR(TempBlob);
    TempBlob.Blob.CREATEOUTSTREAM(Outs);
    Bestand.OPEN(FileName);
    Bestand.CREATEINSTREAM(Ins);
    COPYSTREAM(Outs,Ins);
    Bestand.CLOSE;
    ERASE(FileName);

    Hm.. try not to save it as a .zip file after extraction from base64.
    So save it without extension, and unzip it with the unzip code in my link
