Help with IntPtr Please?

jshimkus — Fri, 22 Oct 2010 17:17:05 GMT

I have these warnings that I cant figure out how to clear up...

'Public Sub New(oldId As Inter)' is obsolete: 'Use ObjectId(IntPtr)'

The highlghted lines of code are are all like this one....

oInputID =New ObjectId(CType(arInputArgs(0).Value, Integer))

I dont understand how to implement the correction

Could someone explain IntPtr and show me how to correct this line?

Thanks

Thank you for the links, I see what it does, and I'd like to implement it as we are going to Win7 64 bit soon and this would save me from changing some code, but I still dont get how to change my code, all the examples dont pertain to autocad and ObjectIds so they are'nt helping me much. Can you gimme a push?

Here's a little more of the code...

Dim oInputID As ObjectId

Select Case (arInputArgs(0).TypeCode)

Case CType(LispDataType.ObjectId, Short)

oInputID = CType(arInputArgs(0).Value, Autodesk.AutoCAD.DatabaseServices.ObjectId)

Case CType(LispDataType.Int32, Short)

'warning occurs on the following line

oInputID = New ObjectId(CType(arInputArgs(0).Value, Integer))

End Select
