Changing Value Of Report Control Dynamically @ Runtime

2006-06-24, 7:55 am

I am trying to use CHANGE() in a report to change the -value- of a
control
at runtime, but this does not seem to work. Any suggestions?

Eg...

LOC:MyControl = 'Old Text'

LOC:FEQ = ?LOC:MyControl

! The following simply blanks out the control on the displayed report
SETTARGET(Report)
CHANGE(LOC:FEQ, 'New Text')
SETTARGET()

Any ideas on how to do this? (No, I can't simply change the value of
LOC:MyControl in the code. The idea is to be able to do this
dynamically @
runtime based on what the user wants to do.)

Thanks!

SETTARGET(Report)
?LOC:MyControl{Prop:Text}= 'New Text'
SETTARGET()

---But that appears to only work for non-variable strings. I want to be
able to assign a new value to controls which refer to -variables-.

If you assign a value to a variable during code execution,
PRINT(RPT:Detail) will print the newly assigned value, so CHANGE is
unnecessary. I assume you can also:
?LOC:myvar{PROP:Text} = 'newvalue'

---Like I said. This appears to work only for constant strings; -not-
for local vars or field vars. I want to be able to change the value of
a local var or field var @ run time, just like you can do in a window
(which -does- work using CHANGE(), of course.)

Any other ideas?

THANKS!

LOC:Variable = '*** Final Page ***' !!! Change the
value of variable in case the control is variable
Report$?Control{PROP:TEXT} = LOC:Variable2 !!! change the
text of constant with property - any property can be changed like this

PRINT(RPT:Detail:15) !!! Print the detail band

This seems working for me - see if it helps

You need to set the USE attribut of the variable.
In the variable field name change
'Myvar'
to
' MyVar,,?MyVar' ! notice the double ,,

You can then refer to it in the code given in a previous posting.

What version of Clarion are you using? This definitely does -not- work
for -me- in C5.5. All PROP:Text does is change the 'picture'
(formatting) of a control, not the contents of the control. In the
example you give, therefore, the control will print nothing since the
PROP:Text assignment is not a valid picture format.

Anyone else?
