passing boolean to stored proc as SQLDBtype.bit not working

Hi I was hoping that someone might be able to help me with this.

I'm trying to figure out why my VB.net code below generates 0 or 1 but doesn't insert it when I can execute my stored procedure with: exec sp 0

myParm = myCommand.Parameters.Add("@.bolProMembCSNM", SqlDbType.Bit)
myParm.Value = IIf(CBool(rblProMembCSNM.SelectedItem.Value) = True, 1, 0)

I've tried everything I used to use with Classic ASP and am stumped now.
Any ideas? I will have to do this for numerous controls on my pages.

Thanks in advance for any advice.If you can execute the stored procedure with bit value in database, that means the value passed from application is not right. You may check the input value by inserting into a temp. table or as a return value to the calling app.|||thank you, that is what I thought.

I have printed out the value of the param in the trace and it is 0 which I find odd as that should be accepted as a valid bit, unless I'm totally missing something.

Is there not a way to pass 'true' or 'false' to the SQLDBtype.bit and have SQL Server convert it to 1 or 0?

still working on it here.
thanks again for your input|||What kind of control is "rblProMembCSNM"?|||thank you,

I took your advice and created a temp table and insert all of my values, after all that it was a different parameter I was passing and I was not escaping the ' ...... very frustrating to find that out after everything but I did learn quite a bit in my research.
