Reading tfrxMemoView.Value in runtime

mvkalken

I need to change the overlay image file during runtime, based on a language code in the customer's data.

To do this I have hooked an ' OnbeforePrint' event on the report.

The problem is that when this event occurs, I can access the Memoview with findcomponent, but i cannot read the value that is inside. All i get is the memo's value from design-time (meaning the datasetname and the datafieldname).

I have tried (from tfrxmemoview) the properties Value, Text, Memo.Text, GetComponentText, and ToString, but none of these give me the value (code) of the memo. I can see it in the report when it is printed??

Any clues?

Try to use TfrxReport.Calc function or OnAfterPrint event

I'm not sure about this, but try using Get() in your OnBeforePrint:

StrVar := Get(MemoView1.text);

But keep in might that you probably need to trim the memoview.text value, see this post:

If it doesn't work initially, try putting the value between quotes before calling get(), and play with the brackets as well,
like:
get('[Data_Threat."Score"]')
get('''[Data_Threat."Score"]''')
get('Data_Threat."Score"')

Move your code to the memo's OnAfterData-event, and check out the TFrxMemoView(sender).Text. You can also adress 'value' in this event, but this will be incomplete if your memo contains more than one expression.
