GhostScript on Windows 10

PDF Generation for PowerBuilder Classic 

 

   Most PowerBuilder developers know that the DataWindow object class in PowerBuilder (PB) Classic utilizes the open source (GNU) version of the GhostScript (GS) software to convert PostScript printer output into an Adobe PDF (Portable Data Format) file. The challenge this year for PB Developers moving into the MS-Windows version 10 domain, is that all drivers must be signed in order for the new O/S to accept the driver. This creates an issue for the GS installation as even the latest version 9.21 does not supply signed MS-Windows drivers.

One of the "new" features in PowerBuilder 10.5 was actually initially introduced in the PowerBuilder 10.2 maintenance release. The folks at Sybase finally addressed a number of fundamental issues with database tracing for deployed applications.

Trace File Location
Users are often running under accounts that don't have Administrative or Power User privileges. As a result, they may not have sufficient rights to create a file in the WINDOWS directory, the very directory where a deployed application was hard coded to store the trace file. We've been able to specify an alternative location for applications run out of the IDE since PowerBuilder 6.0 by setting the DBTraceFile parameter in the database section of the PB.INI file. It wasn't until these new database tracing features were added that we gained this ability for deployed applications.
