Making Global Variable from for loop???

[Sabour]

how to use set variable after the for loop?

i mean something like this

For ....
Variable C
Next
Variable C ' if set variable C to display the value always zero :(

I for one have no idea what you mean. Obviously English is not your first language, which can make it difficult, but can you try to explain again more clearly?

sorry man

For ....
'End Of For
Variable C = "A" 'Example,Variable C always Dynamic
Next
Variable C ' In here variable C value is zero
how to use Same Value the VariableC in End of For Loop to be used in Next phase

Dim C As String

For...
 C = "A"
Next

C = ""

i think....

 

[Sabour]

Dim C As String

For...
 C = "A"
Next

C = ""

i think....

no i mean i want in Next the C variable same like in For,in this case the value is A... i cann't set the value because the variable change dynamicly

If you mean that you want the value of the C variable to have the same value after the loop as it did in the loop then it does. Once the loop is complete the variable will contain the last value assigned to it in the loop. Are you saying that you actually want to keep all the values assigned to the variable in the loop? If so then you can't use a single variable. One variable cannot contain multiple values, so you'd have to use an array or collection instead, so that it can contain all the values from the loop.

Dim var As Integer = 0

MessageBox.Show(var.ToString()) 'Shows "0".

For i As Integer = 1 To 10
    var = i
    MessageBox.Show(var.ToString())
Next i

MessageBox.Show(var.ToString()) 'Shows "10".

Dim arr(10 - 1) As Integer

For i As Integer = 0 To arr.GetUpperBound(0) Step 1
    arr(i) = i * 100
Next i

'arr now contains all the values assigned in the loop.

For Each var As Integer In arr
    MessageBox.Show(var.ToString())
Next var
