Re: What fool proof way exist to initiate PC Activities (Call PC programs)(from 5250 and Browser(Webfacing)) with the possibilitie to send/retrieve parameters??

James,

Interesting! But first comes first!!
We will first have to communicate with the PC application the to be used 
reference (or receive back the used reference) to the object on the IFS.
When we have that we can start worring about how to store and how to represent 
the object from within the iseries on the PC.
Do you know how that can be done??

Regards,
Eduard.

I'm a quick learner.....
Learn we what a Datalink field is and how this could 
help me.

A Datalink field is a field in a database file, that 
explicitly points to some other object (generally in the 
IFS), in a way that is managed by DB2. It was introduced 
after V4R2, but by V4R4.

As I recall (and it's been a few years since I dabbled in 
datalinks), to create a file with datalink (or BLOB or 
CLOB) fields, you have to do it from SQL, rather than from 
DDS, and you have to either have journaling enabled on the 
library, or use special options to bypass a lot of the 
checking DB2 does on datalinks, in order to do it.

I'm sure there's someone else who knows more about 
datalinks than I do; all I managed to accomplish with them 
was to get QuestView (tm) to provide minimal support for 
them.

At any rate, from what I've said, it should be clear that 
a datalink field would allow you to put a protected 
reference to your captured signature image into a 
database, and assuming you need to deal with the file from 
a terminal environment, it would certainly be easier to 
deal with than sticking the image into a BLOB (binary 
large object) field.
