Please I really need help with learning code for vb.net.I need to make a procedure that computes the exponentiation(base^êxponent).How do I write a check number function that receives a number(type string),that validates a parameter as a number,and returns a Boolean value that indicates if the number is valid or not.I am writing a program that will compute the exponentiation of the "Base" number raised to the "exponent" number.help:

I am not sure how to do the code,for this type of program.

[IO-error]

Then your not really writing a program, your just waiting till others script it for you...

I have no idea how it's written either, but if I have to do a calculation, first that comes is the number, then the calculation symbols, then another number to calculate with.

ex.: 1+1
+ | Add | 8+7
- | Subtract | 11-10
* | Multiply | 7*8
/ | Divide | 8/2
^ | Exponent | 2^4
Mod | Modulus | 15 Mod 10

Get it now?

I have no idea what's the second thing you are asking for, but maybe you can explain that later. With the sub procedure, just create one and allow it to accept two variables, something like, Var1 and Var2. Call the procedure something like... er... Exponent?

Add a line: Exponent = Var1^Var2

And voila, call the procedure and you should get the answer. Sorry, is this answering your problem?
