STD Framework - Updated BASE64 Example!

** Hot News **

STD Foundation Classes

Updated BASE64 Example Application released!

 

     Software Tool & Die Inc. today are very pleased to announce an updated Base64 Encoding / Decoding example application for Appeon PowerBuilder that was built from the latest STD Integrated Framework (version 2018.2.0.97 released on 2018-03-11) and the newest Appeon PB2017R2 release (build 1769) ...
 

     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.

    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 )

    The Base64 Example - along with the STD Integrated Framework - is also written to support the PowerServer Web product. Thus, the Base64 Example application can also be deployed to your favourite Web Browser and executed as a web application as well.

    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, PowerServer and Web Services by clicking here!

Enjoy!

Regards ... Chris
