This is the method that you use to create a GZ compressed file, from a given input file. The resultant GZ file can be loaded up with any standards compliant GZ file reader.

x = object.GZCreateGZ

The syntax of the GZCreateGZ method has these parts:

Part Description
object A Cryptocx v7 control.
x A string that becomes either "TRUE" or "Error: xxx" where xxx is the error message.

Remarks You can load the resultant gz file up with any common gz file reader.

theResult = Cryptocx.GZCreateGZ

'' Check to see what has happened (if the compression went ok without errors)

  '' Ok, the Compression went well with no errors and the gz file was created
  MsgBox theResult
