Sorry, the lnInt1 should have been removed. I had been using that as the first parameter in the SQLConfigDataSource() function.

The code I use to check the Win95 registry is in the Files section of the UT under Classes/VCX, Registry.zip. This file was uploaded by Rick Strahl of West Wind Technologies.

I set up the following in my application to use the registry.prg functions:
#Include registry.h
set procedure to registry
oRegistry=CREATE("Registry")
DIMENSION taVals[1,2]
lcRegSubKey = "SOFTWARE\ODBC\ODBCINST.INI\Microsoft ODBC for Oracle"
lcRegHKey = HKEY_LOCAL_MACHINE
lnVals=oRegistry.GetEnumValues(@taVals, lcRegHKey, lcRegSubKey)

I modified Rick's code to take out the example code. I left all the constant definitions in the registry.prg.

The lcRegSubKey and lcRegHKey is where the ODBC DSN information can be found in the Win95 registry if you browse it with Regedit.exe utility.
