Drew,
It looks like it cannot use Win API directly but:
<<<+ quoting CR help +>>>
The Seagate Crystal Reports Formula Editor and formula language are powerful
tools, enabling you to perform a wide variety of report-related tasks easily
and efficiently. The formula language is expandable as well. That is, while
it already includes a large selection of useful functions, it also comes
with the ability to accept new functions that you define to meet your needs.
User Defined Functions that are recognized by the Seagate Crystal Reports
Formula Editor can be created in a Dynamic Link Library or, for 32-bit
environments, in an Automation Server.
<<<- quoting CR help ->>>
I.e. you can create helper DLL/ActiveX Dll following CR extention call
protocol and use Win API this way...
But what Win API calls are needed for reports' generation?
HTH,
Shamil
