ReDim....?????

[thurst0n]

Ok...
My Goal: To make my form fade out when I exit the program...
My Problem: I cannot reset A as A-.05

Here is what I did

I set A as Integer
A=1 BLAH BLAH BLAH

Then I have my button and I enabled my timer

I set my timer to 100 (1/10 of a second)
In the timer code i have this...

MyBase.Opacity=(A-.05)

And it does that every 1/10 of a second, the problem then is that it always thinks A=1

I want it to reset A to A-.05 (.95) so that the opacity keeps getting smaller

I know that on TIBASIC I would simply do A-.05->A But that does not seem to work in VB.NET


So what do i Do? :-D

The problem is that you are declaring it as in integer and integers are whole numbers (no decimals) switch it to a single and you'll be all good.

oh haha, i'm such a idiot That takes care of one issue, that I didnt even think about...Thanks

But what i really want is to know how to Redefine A using A...

[Edneeis]

You just assign it to itself.

A=A-0.5
'you can also shortcut adding and subtracting
A+=1 'adds 1
A-=1 'subtracts 1

[thurst0n]

So should i not have set it as a string? or...

so it'll look like this

A=A-.05
MyBase.opacity=A

like that?

[Edneeis]

String? You mean Single? You can't use A without declaring it. Actually if you are just changing the opacity then try this wherever you need to decrease the opacity:

Mybase.Opacity-=0.5

[thurst0n]

That's a good idea, i didnt think of that thanks!

but say i did wanna reset A how would i do that?

[Edneeis]

Reset it to what? 100%

MyBase.Opacity=1

I believe Opacity is just a single between 1 and 0, 1 =100%, 0 =0%, .5 = 50%

[thurst0n]

Right i know that...

I'm sorry my termonology is crap...

Not reset opacity

like Re Define "A" Is what i meant....
I think this is a wonderful example of how there are many ways (I count 3 in this case) to do one simple thing

1) set opacity value as a number then subtract .05 from it
2)Mybase.Opacity-=0.5
3)and if anyone followed the one that i thought was the only way from the begnning

[Edneeis]

I'm still not sure what you mean by reset? Reset what? Explain it further and maybe I'll see what you mean. What do you expect to happen when you reset?

[thurst0n]

Not reset, but like Re Define.... The string "A" Redefine it as a new number...like

'Define A
Dim A As Integer
A=1

'RE DEFINE A
A=A+1

This is what i mean, i think this is how you would do it...It sets A as a new number, and if it was in the timer, it would do that every 10th of a second thus making the opacity smaller every 1/10 of a second

[persianboy]

i know you;ve already done it but anyway dont forget to declare the A variable outside the tick handler of the timer, so it value doesnt reset each time the procedure is called

[persianboy]

its doesnt seem to be very goodway to write the code, but anyway in can help you in your "redefinig variable" question

Dim a As Single
    Private Sub Form1_Closing(ByVal sender As Object, ByVal e As System.ComponentModel.CancelEventArgs) Handles MyBase.Closing
        Do While Me.Opacity > 0
            a += 0.01
            Me.Opacity = 1 - a
        Loop
    End Sub

Thanks, yeah it is a bad way to write the code, but i'm a beginner so that's what i'm here for...I'm only a junior in High School, I"m learning it at my High School it is a great class, the teachers is great! I also wanted to share the other language he's teaching to the Advanced Comp Sci people is C#, how many other schools are teaching that? to highschool students? that's what i thought!
