Using variable name more than once...

[lidds]

Is there a way that I can use the same variable more than once in a private sub?? Is there a delete variable command so this can be done???

 

e.g.

 

dim simon as string = "hello"
msgbox(simon)
simon.delete()
dim simon as string = "bye"
msgbox(simon)

 

Thanks

You can re-use variables as often as you wish by just re-setting its value.

Dim simon As String = "hello"
MessageBox.Show(simon)
simon = "bye"
MessageBox.Show(simon)
simon = "aloha"
MessageBox.Show(simon)

Sorry should have explained myself a bit clearer. I am actually using a bit of third party software and I can't seem to get it to work unless I keep on declaring a new class to a variable, therefore I am unable to performing a do loop (to tidy my code up instead of loads of repeated code) as the variable name is already declared.

 

Which is why I was hoping there is a way to delete a variable and then re-use it again???

 

Thanks in advance

Any chance you could post a sample of what you are trying to do and what it does / you expect it to do?

Once a variable is defined it cannot be defined again within the same scope, although it can be reused as DiverDan showed above.

This might be from left field, but here goes!

 

Instead of deleting couldn't you use REDIM?

 

dim simon as string = "hello"
msgbox(simon)
redim simon as integar = "15"
msgbox(simon)

You can't redim variables like that, Redim only allows arrays to be resized. Even if you could I fail to see what it would acheive other than making the code lest readable.

I was wondering how you got one hundred plus posts and didn't know something like what DiverDan posted. I understand now what you meant, an example of code would be extreamly useful to help you with us answer your question.

@lidds:

If your variable is an object that is declared as "new", you can simply create another object, as in:

Dim o As ThirdPartyObject
Dim i As Integer
For i = 0 To 10
   o = New ThirdPartyObject()
   ' Use new instance of o here
Next

 

or in C#

ThirdPartyObject o;
for(int i = 0; i<=10; i++)
{
   o = new ThirdPartyObject();
   // Use new instance of o here
}
