What DLL contains components for Report Items Toolbox - RDLC?

[=?Utf-8?B?UmljaA==?=]

Hello,

Mysteriously, the components for the Toolbox for Report Items (RDLC reports
- VS2005 - designer) have all changed to Textbox. There is no List
component, Matrix, Table, Line, Chart, Image,...

I ran VS2005 setup in Maintenance/Repair mode, but that did not fix it. I
uninstalled VS2005 and re-installed it, but that did not fix it. My guess is
that some IT operation in our company has corrupted something on my
workstation. I was thinking of manually choosing items directly from the
components library (in the Toolbox I right click and select Choose
Item/Browse). I tried

C:\Program Files\Microsoft Visual Studio
8\Common7\IDE\PrivateAssemblies\Microsoft.ReportDe signer.dll

but got a message that there were no components stored there. I also tried

C:\Program Files\Microsoft Visual Studio
8\Common7\IDE\PrivateAssemblies\1033\Microsoft.Rep ortDesignerUI.dll

But nothing there either. Would anyone know how to fix this problem of the
missing components in the toolbox for the Report designer of VS2005?

Thanks,
Rich
