Take a look at the CDK tutorial sample on my link page, shown below, Didier.
(Click on the Samples link on that page, and the demos are in alpha order.)

When you run the tutorial, click the bottom radio button: Get Table Window
Cache Settings. It will show you the SAL call to make to detect if
discardable and cache size.

In this tutorial, the sample is reading itself; probably like you want to do
that as well, although you could read in another appl. if you needed to.

Didier,

the discardable feature of table windows was used to save memory in the
ancient times when memory was expensive. These times are gone. Just set
every table (class) to "discardable: no" and "max rows in memory" to
something very large (handle SAM_CacheFull if necessary) and you will always
know which discardable state your tables are in ;-)

Try

Code: Select all

Call SalOutlineItemTypeText( SalOutlineCurrent( ), SalOutlineItemOfWindow(hWndItem),CDK_IT_TableDiscardable, FALSE, sOut )
If SalStrUpperX(sOut) = 'NO'
	....

note: CDK_IT_TableDiscardable = 0x00D4
