String variable please help


Recommended Posts

I need having a variable one string where to hang various fields.


This operation in Crystal Report came then made declaring a field of Stringvar type and hanging gradually the necessary fields.


Practically I have need to carry out of the operations type $V{variable} = $V{variable} + $F{field} under various conditions.


Unfortunately me it seems to have understood that this is not possible in iReport therefore is to ask like being able to make. Thanks

Walmillard, mau72 is after string concatenation.


Mau72 you concatenate strings exactly as you have described ( $V{variable} = $V{variable} + $F{field} ), however you can't 'cycle through' the fields. What you would need to do is more like this:



$V{variable} = $F{field1} + $F{field2} + $F{field3} etc.



If field2 was (say) an Integer you would have to perform an inline cast to String like this:



$V{variable} = $F{field1} + $F{field2}.toString() + $F{field3} etc.
