Hi,
In my database the variable is stored as Type MONEY. I am writing a query to retrieve this information and display it on screen. I keep getting Vb.net error # 13( unable to cast object of type'ABODB.internalfield to type system.IConvertible'.

I am sing visualstudio 2005 and language vb.net.

I tried using convert.todecimal and it doesnt work.

here is a snipet:
Dim test As Decimal
test = Convert.ToDecimal(RSTransferCashierPayment("current_bill"))
MsgBox(test)

Try the old way

test = CDec(RSTransferCashierPayment("current_bill"))

Since it appears you are using ADODB not ADO.Net

Hmm.. try this

test = CDec(RSTransferCashierPayment("current_bill").Value)

There appears to be no 'default' property for ADODB in vb.net
