How do I increment a byte with out casting?want to do any casting. The code below does it but it is hard on the eyes. Dim lineNumber As Byte = 0 Dim incrementer As Byte = 1 For Each line As Line In mCollection lineNumber += incrementer line.LineNumber.Value = lineNumber Next I'd like to do something more like this Dim lineNumber As Byte = 0 For Each line As Line In mCollection lineNumber += 1y line.LineNumber.Value = lineNumber Next Where y is what ever suffix would create that nameless temporary object as a byte with the value of 1. Is there a way to do this? Is there a better way to increment a byte? Thanks, Russ Hi,
You make me curious, why are you using a processor cycles eating command with a byte for this kind of operations and not the normal Integer that fits directly in the accumulatorregisters from a 32bit computer.

dragging along a lot of converted VB6 code and I assume old databases; not that that justifies using a byte. I only mean to explain the environment I seem to be stuck in. When I've been here a while they might answer my asking that question with a "Fine you're so smart go fix it". Regardless, is there any way to increment a byte that doesn't look so goofy?

Implicit won't work with Option Strict on. "Option Strict On disallows implicit conversions from 'Integer' to 'Byte'" I'm hoping I can create a nameless temporary Byte with a value of 1. I've seen this kind of thing done with suffixes. kosherpi***@hotmail.com wrote:

When option strict is on that line produces this error message: "Option Strict On disallows implicit conversions from 'Integer' to 'Byte'" I need to create 1 as a byte but I'd like to do it with out having to create a variable or an explicit cast.

One last question: Which of these do you think is the least horrifying practice? Dim LineNumber as Byte = 0 Dim Incrementer as Byte = 1 LineNumber += Incrementer - or - Dim LineNumber as Byte = 0 LineNumber += Cbyte(1) Short of abolishing all bytes that ever need incrementing these seem to be my only options under option strict. Thanks for all your help, Russ
