Base64 example from an ANSI text file!

     Base64 encoding and decoding is a critical  feature when processing XML and JSON files that contain binary datum. As well as using PowerBuilder's PBDOM feature, an XML DataWindow or interacting with Web Services that pass binary data back and forth (ie: JSON in a RESTFul web service). The received binary data will be in base64 encoded format - which is unusable to your PB application unless decoded (converted back) to its original binary state. Conversely, binary data that your PB application needs to send to other XML or JSON based applications must be converted (encoded) into the base64 standard.

 

PowerClient based Base64 example using Unicode text file!

 

Error handling for corrupt (incomplete) or wrong encoded Base64 files.

    The Base64 Example application utilizes standard Microsoft Base64 API's supplied by the MS-Windows O/S. These API's are now embedded in the framework's "nc_crypto_master" object class and easily called from your PowerScript code, as follows:

• lo_crypto.of_base64_stringtobinary ( lblb_image , ls_base64 )

Base64 file translation into an image (or any other binary format for that matter)!

 

    The latest Base64 Example - along with the STD Integrated Framework is also able be used with PowerClient and PowerServer (Cloud) v2022 applications. Thus, the Base64 Example application can also be deployed to your favourite Web Server for convenient deployment. 

 
    You can download the Base64 Example application from the STD Framework's website by clicking here! You can also download either of the free open source STD frameworks for PowerBuilder, InfoMaker and PowerServer version 2022 R3 by clicking here!

   Note: The Archive folder on SourceForge contains older versions of the PB Base64 application for older versions of PB!

Enjoy!
