Option Strict issueHi
I have a vs 2003 project which I have just imported into vs 2005. Now I am getting the "Option Strict On disallows operands of type Object for operator '='. Use the 'Is' operator to test for object identity." error on the 'Case "Main"' statement in the below code; Select Case Row("Contact_Type") Case "Main" ..... End Select What is the problem and how can I fix it? Thanks Regards The Case "Main" is doing the equivalent of:
Case When Row("Contact_Type") = "Main" In this case you are comparing an object to something using the = operator and Option Strict does not allow that. Row("Contact_Type") returns an object that you are expecting to conatain a 'boxed' string so you need to convert it to a string before you can compare it to a string: Select Case CType(Row("Contact_Type"), String) Case "Main" ..... End Select should 'fix' it.

The reason is that Row("Contact_Type") returns an object. Cast is as an integer and it will be OK: Select Case Row("Contact_Type").ToString Case "Main" .....

Cast it as a string or use the objects .to string method when apropriate and it will be OK Select Case ctype(Row("Contact_Type",string) Select Case cstr(Row("Contact_Type") or just Select Case Row("Contact_Type").ToString AFAIK this problems should have also occured in previous versions of VS when option strict is On The bether code has Option explicit , and Options strict on above every code block Regards Michel Posseth Show quoteHide quote "Eric Moreau" <eric.moreau_N_O_S_P_***@videotron.ca> schreef in bericht news:%23lFYd8DOHHA.2236@TK2MSFTNGP02.phx.gbl... > Hi > > The reason is that Row("Contact_Type") returns an object.

Option Compare options for all new projects. I strongly recommend you set Explicit and Strict to "On". Set Option Compare to Text for compatibility with VB6 or Binary for compatibility with the framework's System.String class. Mike Ober.
