ReDim....?????

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...

You just assign it to itself.

VB Code:

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

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?

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

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

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

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%

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

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?

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

Code:

---

'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

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

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

Code:

---

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!
