Select Case problem (easy but cannot find answer)

[Trowser]

Select Case DBrec![build_weapons]
Case "", 0, Null

how can I get that Select Case to recognise a null field??

I dont think you can directly - what about using

Select Case IIf(IsNull(DBrec![build_weapons]), "", DBrec![build_weapons])

Case "",0

#NULL# is a tough issue because you can't evaluate it other than if it's null. Select case is looking for a value and #NULL# data cannot be evaulated to anything other than #NULL#. What you might do is use CASE ELSE and then when the comparison falls through all the other case statements you can catch it by using the standard "if isnull(fieldname) = true then (operation)" evaluation.

thanks lads no wonder I was having such a mare trying to get it to work

I did do one other thing I changed the DB so that its default value was "" which I could evaluatate for but useful to know that I can't do that.
I will try sonofemidex1100's solution see if that works aswell.

Ok tried it and that works fine aswell
Thanks alot guys to answers
Change DB or use that iffy

Of course you can test for it...Select Case DBrec![build_weapons]
Case "", 0, IsNull(DBrec![build_weapons]

Based on what you are looking for, try:

Select Case Val(rsADO("test&quot & vbNullString)

Case 0 'Will catch if field is a NULL, "", or 0

Case Else

End Select

Or,

Select Case rsADO("test&quot & vbNullString

Case "0", vbNullString 'Will catch if field is a NULL, "", or 0

Case Else

End Select [/b][/i][/u][sub]*******************************************************

??

IsNull() returns True or False. The value of a field with Null does not. [/b][/i][/u][sub]*******************************************************
