Spliting and adding - 1llusion - 02-09-2011

Hi :epic:

Well... I'm doing final stage of my Math Bruteforcer and I found a little problem:

I split the math problem, so I can add some variables. Well I do this:

Code:
arrText = TextBox1.Text.Split("x")

Now, I need to add "x" variables between each split.

Problem is, I don't know how many parts there will be, so I will somehow have to loop through all parts and add all x'es...

Any idea please? Smile

Code:
result = New DataTable().Compute(arrText(1) & x & arrText(2)......, Nothing)

Thank you very much!!! Have a great day!!!

UBound(arrText) or arrText.GetUpperBound(0) should do it.

I'm not sure what you want to make though.

I thought of this, but i'm not sure if it helps...

well... I want the app to add: & x
to all arrText parts.

So in the end it would be:

Code:
arrText(1)  & x  & arrText(2) & x  & arrText(3)

but instead of this, I'm looking for code that does this for any number of arrays Smile

Thanks!

Code:
For i As Integer = 0 To UBound(arrText)

      MathStr &= arrText(i) & If(i < UBound(arrText),"" ,"x")

Next

result = New DataTable().Compute(MathStr, Nothing)

This should work. I don't have compiler here at the moment to check.

works perfect Smile

Well... time to teach my program that 1 + x = 5 /// x = 1002 is wrong answer....
