There are other ways, but they involve either of two things: Template
change or some code manipulation.
The template change is easy. Open one file in the C4/template
directory, the ctlbrowa.tpw. First locate a line starting with:
#CONTROL(BrowseUpdateButtons
In my template this is line 120. Next locate this line:
#PROMPT('&Update Procedure',PROCEDURE),%UpdateProcedure
this is line nr. 127 in my template. Add the following line right
below it:
#PROMPT('Parameters:',@s255),%UpdateProcedureParameters
Next locate this line:
%InstancePrefix:CallUpdate ROUTINE
This is nr. 500 in my template after adding the line above. Few lines
below you will find this code:
CLOSE(%ListView)
LOOP
GlobalRequest = LocalRequest
VCRRequest = VCRNone
%UpdateProcedure
LocalResponse = GlobalResponse
Change it to:
CLOSE(%ListView)
LOOP
GlobalRequest = LocalRequest
VCRRequest = VCRNone
#IF(%UpdateProcedureParameters)
%UpdateProcedure %UpdateProcedureParameters
#ELSE
%UpdateProcedure
#END
LocalResponse = GlobalResponse
This does it - you now have a parameter prompt on the update buttons
properties (action tab) where you specify the parameters in the normal
format:
(Loc:MyField, Loc:MyOtherField)
ie, with the surrounding paranthesis.
