Report runs in Visual Studio, and in Web Add-On CR Viewer, but not in WinForms CR Viewer Control

[Former Member]

I have a Crystal Report that runs fine in Visual Studio preview mode, and it runs in an old Crystal Decisions, Inc. web based viewer control, but in my C# .NET Windows Forms application it throws the error below. Is there any way to get the report to run in the Windows Forms application without editing the report? We have a large number of these reports and it would be a lot easier if we didn't have to edit them all.

CrystalDecisions.Shared.CrystalReportsException: Load report failed. ---> System.Runtime.InteropServices.COMException: Error in formula name 'm ({@Ext_Q_Total}, {T_PRO_DAT.LEI_TEAM}', reserved characters '{', '}', '@', '?' cannot be used in formula name.

Thank you,

Joe G.

Hi Joe,

Correct, CR does add them which is why you cannot use them, something else in the report is causing the issue.

Did you run the app and use the Formula to check all of them?
