Crystal Reports vs WinForms problem

I have a WinForms application (written in VB.NET, if it matters) that has a built-in Crystal Report to track application usage (call utr310.rpt on it). Our reporting guy made a small contribution to the report that was in production and I'm trying to test it (let's call the new utr311.rpt), except I'm getting the following error:

System.Runtime.InteropServices.COMException (0x80043AE3): Invalid TLV record.
   at CRAXDRT.IApplication.OpenReport(String pFileName, Object OpenMethod)
   at WinFormsApp422.mCrystal.CrystalReportShowSingleParameter(String sReportName, Object objParam, Boolean& bPrint) in C:\2008-Projects\WinForms-applications\WinFormsApp422\code_Modules\mCrystal.vb:line 161

I cannot make the heads or tails of this error. Have any of you seen this?

a few questions for you?



  • What changes have been made?
  • Was the developer using the same version to modify the report using VB.NET?
  • Can you open the report at this location using the Crystal Reports developer developers and the version available in VB?
  • Is the report file size greater than zero?
  • Is the path correct?
