Creating variables at Run-time

[thiago777]

Is this possible in VB? for example, in PHP you can use the "$$" like $$future_var in place of a variable name that will be created only later.

thanks.

I don't believe this is the case unless you create application variables or ones created in classes. HTH.

Sorry but I didnt understand you. What case are you talking about?

[kenobewan]

Just meaning your question, the case in point.

To what benefit does that offer?
You could make an empty/blank varriable if you wanted.

Sometimes creating variables dinamically is the only solution for certain problems.
The new variable (created in run-time) could have the name specified by another source for example.
I've already used this in PHP.. but I dont know if it works in vb.net. In php, as I said, you use the $$ symbol to specify the future identificator.

And in those cases you cant make a blank variable, once you dont know the name of it yet. It is named dynamically.

Why do you need the name to change?
I really don't see what that offers.
I mean you could create a Control object.
Then assign the Name property of it and stick spare data in the Tag property.

Or better yet create a Dictionary or some sort of name/value pairing.

I dont really see this either when you can variables "at run time" in the page load or page init events. Please give examples.

This is called Variable Variables. Take a look here:

I wanted the same effect but in VB .Net

thanks

That still sounds similar to a dictionary.
And as far as just variables, it still doesn't seem beneficial, more of an addional complexity that makes code harder to read.
Now, being able to refer to classes by a string (Reflection), seems rather usefull.

But yeah just make a dictionary?
myd.add("foo"," bar");

string whatfoois=myd["foo"];
