FamilyParameter Set Value

[Anonymous]

While trying to set the value of a FamilyParameter in Revit, I get this error

"Attempted to read or write protected memory. This is often an indication that other memory is corrupt."

The code is as follows (and yes, it is inside a BeginTransaction) ...

For Each rvtFamilyParameter As Autodesk.Revit.DB.FamilyParameter In rvtFamilyManager.Parameters

If rvtFamilyParameter.Definition.Name = strName Then

rvtFamilyManager.Set(rvtFamilyParameter, strValue) ' Error occurs right here.

Exit For

End If

Next

Any ideas?  Is it really bad memory?

Thanks,

Randy

Seems that you are using Visual Basic(?). I don't have much knowledge about it. But just couple of things:

- What is rvtFamilyManager object. Is the class defined by you or API? If it's made by you there might be some problems inside the parameter setting function

- How about "strValue"? Where does it "point" to? Maybe the object it is refereng has gone out of it's scope?

As it turns out... I wasn't doing anything wrong.  The error was being generated by a few family files.  About 90% of them worked just fine.  If anyone knows why this error is generated by certain family files, I would like to know that.

Thanks,
