Using parameters in Crystal 8.0 RDC with Delphi 5

[pwesson]

Has anyone had any luck getting this to work at all?<br><br>About the only thing I can do is select the report I want to print and print/preview it? <br><br>What I really want to be able to do is locate any parameters in the report and then set the values for them... but everytime I do that I get a &quot;Type Mismatch&quot; error! I don't understand, as my report parameter is a Date (also tried Date/Time) type field and the value I'm passing to it is a TDateTime field (TDateTimePicker)?<br><br>Anyone had any luck with parameter passing in CRW 8 / Delphi 5?<br><br>Paul

I have just upgraded to version 5 but i use the following syntax and it seems to work

crpe1.ParamFields.add('CDV', '');
Crpe1.ParamFields.value := PARAMSTR(5);


cdv = crystal param

and i am just passing a dos param into the project

hope this helps.

Ps - are you finding delphi 5 using the vcl a lot slower than delhpi 3.
