Dynamic font changing in a Datawindow

Righto, I have looked all the way back to 1996 for help on changing the
font but the answers haven't helped.

I am using ver 7 of PB and my datawindow is invoked from a DDDW. Within
the datawindow is a SQL select to retrieve the data that will appear in
the window.

What I need to do is change the font dependant on the value of another
field.
I have tried using the escapement expression under the font for the
field in question using the following if stmt:
if (Mid (account_number,1,4) = '1234',
this.object.vendor_name.font.face = 'AR PL KaitiM Big5',
this.object.vendor_name.font.face = 'Tahloma')

But I get "Invalid argument to function" when I verify the stmt.

I have considered using the Modify method - by exporting the datawindow
but and not sure how/where to put the stmt - adding to the end of the
code or on the line that builds the column seems to get a syntax error.
If Mid(account_number,1,4) = '1234' Then
dw_cust.Modify("vendor_name.font.face = 'AR PL KaitiM Big5'")

Can anyone offer any suggestions?

Thanks,
Pete

What does the above mean?

Where, in DDDW or in primary on which the above mentioned DDDW sits?

That's short for Drop Down Data Window - basically a menu. When the
application is run a window appears and the user selects a report from
the drop down list, which invokes the appropriate Datawindow, which
then executes the sql to retrieve the data.

Well, I ended up asking the guru guy at work who found some spare time
to assist me - it turns out the datawindow was accessed by an ordinary
window but the way it got called was rather obscure and via several
other windows! So in the end it was just a matter of referring to the
object and changing the font.face thus
dw_preview.Object.name_1.Font.Face = 'AR PL KaitiM Big5' as well as the
codeset.
