Error:502 Invalid Text or Object Handle<br />
Formulas.SetIndex(1) &lt;PEGetHandleString-Formula<wbr /> Name&gt;<br />
<br />
<br />
I got the said error when i tried changing the value of my formula from Delphi 7.(Note that I'm using CRW 9.2.2, Delphi 7 and correct VCL).<br />
<br />
Crpe1 is from TRCrpe, then i added the ff code in Delphi:<br />
Crpe1.FormulaByName('Formu<wbr />la1').Form<wbr />ula.Text := 'Test';<br />
<br />
That line caused the above error to appear. I tried executing Formulas.Count in delphi and was able to get the correct number of formulas in my report. I even tried to get the value of Formulas.IndexOf('Formula1<wbr />'), and was able to get a value for this.<br />
<br />
Pls help. Thanks.

How to Change the value of a Formula of the Report from Delphi

Crystal Reports is a business intelligence application from SAP SE. It is used to graphically design data connections and report layouts from a wide range of data sources including Excel spreadsheets, Oracle, SQL Server databases and Access databases, BusinessObjects Enterprise business views, and local file-system information. Report designers can place fields from these sources on the report design surface, and can also deploy them in custom formulas (using either BASIC or Crystal's own syntax), which are then placed on the design surface. Crystal Reports also supports subreports, graphing, and a limited amount of GIS functionality.
