Hi everyone,
I'm brand new to Oracle. I'm using the Oracle Forms Builder and I'm trying to set the "Initial Value" (in the Property Palette) for the "User" (text) field to autopopulate the currently logged in user.
For my "Date Created" field I used $$DATE$$ and it works great but $$USER$$ and $$SYSUSER$$ don't work.
Any ideas?
TIA,
-MC

Hey thanks,
What worked for me is placing the WHEN_NEW_RECORD_INSTANCE trigger in the data block.
On a separate note, I'm trying to place a file upload control on the form so a user can click the button, browse their hard drive, select a file, and have it placed in the field (or item). In this case, the item references a field in the table that is a BLOB.
Can this be done through Forms 10g or would I have to sprinkle in some Javascript into the form in order to make this happen? If so, where/how would I go about inserting the Javascript into an Oracle Form?
I appreciate your help,
-MC

Simple answer yes it can be done :)
technical bits:
you need to downlaod and install the oracle 10g demos (unsure where scan oracle.com - and let me know)
These demos contain example clent server operations one of which is file manipulation.
Then all you need to do is get the file into a blob - Forms should be able to perform that action!
NB: I have heard romours that claim its better to keep these files outside of the database, via external table or similar method (i.e. a table with server size path) then open the file from there.
But who really knows - you could ask Larry - but I don't have is private number! :)

ok so obviously there's no way to integrate html or javascript within Oracle Forms.
I've searched Oracle.com and the internet until I'm crosseyed and could only come up with two options:
- The Oracle Forms File Upload Utility
and
- The WebUtil add on for Oracle Forms
The former requires the use of Java Beans, Java classes, and a PL/SQL library while the latter came with a 64 page user guide that I'll have to dig through to find what I'm looking for.
Granted I'm brand new to Oracle and I certainly hope there's something I'm missing here but coming from the Domino development environment where adding a file upload control to a form takes all of 30 seconds via a point and click menu, I find it hard to believe that one has to jump through all these hoops in order to facilitate this in Oracle Forms?
Does anyone know of a simple way to add a file upload control (enabling a user to browse their hard drive and upload a file to a field in the form) to an Oracle Form?
I also have a Javascript routine that does exactly that, does anyone know how to integrate Javascript code within an Oracle form, sort of like "Pass-thru html"?
I appreciate any tips,
-MC

"ok so obviously there's no way to integrate javascript within Oracle Forms." -- I don't know how true this is......(?) - JDEVELOPER?
but you are correct about WEBUTIL - although there are lots of examples that come with WEBUTIL once it is insatlled. - you don't need to install all of it either (just the bits you are after).
The (not so good) alt: load the directory structure from a text file (i.e. dir >loadme.txt)into the database - then provide the user a way of navigating (perhaps tree view - although I don't the how you would force the heirachary(?)) - I have see silmiar letting users create play lists.
Sorry for the bad news (if you downgrade to 6i (client-server) its all much simpler.
