 Option Strict Errors FIGURED OUT
My program works fine with option strict off but my instructor says it has to be on. Can someone tell me why I'm getting errors and how to fix them?? My errors all say Option Strict On disallows implicit conversions from 'Double' to 'String'. I highlighted where I'm getting the errors. And when I change when I change the grpSalespersons.Text to SP, grpTotalSales.Text to TS, and grpAverageSales.Text to AV; the errors go away but my program doesn't work anymore. Please help!
' Set up constants for Base pay(BP) = $500 and commission(CM) is 6%
Const BP As Double = 500.0
Const CM As Double = 0.06
Dim SA As Double
Dim GP As Double
Dim SP As Double
Dim TS As Double
Dim AV As Double
Private Sub btnGross_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnGross.Click
SA = Val(nudSales.Text)
SP = Val(grpSalespersons.Text)
TS = Val(grpTotalSales.Text)
AV = Val(grpAverageSales.Text)
' Compute value and display in Gross Pay
GP = BP + SA * CM
txtGross.Text = Format(GP, "$#####0.00")
' Compute value and display in Salespersons
grpSalespersons.Text = SP + 1
' Compute value and display in Total Sales
grpTotalSales.Text = SA + TS
' Compute value and display in Average Sales
grpAverageSales.Text = TS / SP
End Sub

SP is a double..... SP + 1 is still a double. A Textbox is a string.... you have to conver the number to a string......
grpSalespersons.Text = (SP+1).ToString

I don't think that twisted is bothering to read our posts. Have a look at all his previous posts and you will find he is using VB6, but he keeps ignoring us and posts in this Forum. (As well as posting it in the Classical VB section )

Been a very long time since I did ordinary VB at Uni, so I may be wrong but doesn't VB use variant and doesn't have events or handlers? Even still he shouldn't be posting in the ordinary vb forum in that case.

Well, VB6 doesn't have the Option Strict setting, at least not that I am aware of.... I thought that was added to .NET specifically to allow VB6 developers to "feel comfortable" with implicit conversion.

Yes, VB6 has variants, yes VB6 has event and event handlers.... but the code he's posted is clearly VB.NET....

My bad wording there, I meant variant instead of object  .

Guys I am using VB.Net I just posted in VB6 before I upgraded. Thanks for the help it worked like a charm. I knew what I needed to do but am such a beginner it is killing me. If you guys get a chance check out the other post by me. Can't seem to figure it out. Thanks again!

HI techgnome,
"Yes, VB6 has variants, yes VB6 has event and event handlers.... but the code he's posted is clearly VB.NET...."
It is NOW. But it wasn't before he edited it. He was treating TextBox.Text as a variant.
Anyway, he has since confirmed he is working in VB.NET, but have a look at all his recent posts and you will see what I mean (including the one on Classical VB).

Right. I can now see where you are coming from. You are trying to carry on with VB6 coding in .NET. Hence the problems with previous posts. Looks like your instructor is deliberately trying to emphasise this. Best of luck
