Defining session variables
« on: July 30, 2009, 06:35:51 AM »
In a straight Clarion app we use global variables. The WebServer docs clearly explain that one needs to use session variables. It shows how to reference a session variable.

How do you define a session variable. Is it simply by using it?

Thanks,

Drew

Hi Drew,

yes, you don't need to "declare" session values. Rather you just "use them". So use SSV (SetSessionValue) to create, or update one, and GSV (GetSessionValue) to read it.

If you read a value that does not exist then a blank string is returned to you (ie 0 if you are reading into a long etc.)

Cheers
Bruce
