Modify Expression Editor
How about improving on the Modify Expression Editor a bit? We have some
quite complicated expressions, and the tiny little MLE control that PB uses
to allow us to edit expression is very clumsy (and yes, I do realize about
the elipse to bring up the modal Modify Expression window - which contains
an only slight less tiny MLE for editing the Expression).
Not to mention that embedded Returns in the expression can cause the
computed field to behave funny.
How about a real editor, complete with color markups, support for
indentation and carrage returns, AutoScript even!
Oooh,...DataWindows Expressions for contraints on grid datawindows...
This may seem like an unholy thing to do to a datawindow, but I ran
into a place where it was appropriate. First, I decided that I wanted to
use Don Roof's dropdownfilter service for datawindows, which is
triggered by clicking on a small bitmap icon which is supposed to be
positioned next to the column heading. This is fine for the tabular
style that Don's samples used. However, I wanted to use a grid-style
datawindow to allow my users to resize columns while the application is
running. Unfortunately, the datawindow tries to resize the bitmap when
the column is resized, makin...how to write loop expression in Datawindow Expression?

There is no direct way. You could, however, write a couple global

computed field in the DW)... but you're probably better off doing this in a

Can I make use of the properties of objects in the expression?
For example, can I set an expression in COLUMN_A's color property which

properties in expressions. Can anyone help me? Thanks.
You can use the Describe() function.

I'm Using PB703 Build 10213
I'd like to know if there is any DataWindow expression function that could
give me the current Column on the DataWindow! Sthg like GetColumn() method
I've got a tabular datawindow, where I want to change the Border of a column
when it is the current column (Just for the current row, too)! Is there any
other way to do It?
Check your event arguments for "DWO". That is a pointer to the current
To check the name for example:
ls_var = DWO.name
Hope that helps.

I'm trying to do something that sounded so simple, but I cannot figure it
out. I want to change the background color of a "cell" in a grid datawindow
when it has focus. Not the background color of the entire column or row -
just the cell which represents the current row and column. I cannot find
any datawindow function that tells me the current column. Can it be
determined with the Describe function? I tried "GetColumnName" inside a
Describe, and of course that is not valid. All the datawindow functions
seem to apply to rows, not columns.

There is already a Protect property for datawindow columns which can be an
expression. Did you mean the ReadOnly property of the whole datawindow?

You should post this in the powerbuilder.datawindow section.

Not at this point.
