Add (rather than concatenate) numbers from two text boxes

[killuminati]

Hi. Juts started to try vb and have been getting along fine until I tried to create a simple addition. I have to text boxes which a user enters to scores in. All I want is the third box to produce the addition. But everytime I try it just puts the two together. So for example if the two numbers were 23 and 24 it would produce 2324. I relise this is probably extremely simple, lol, but please help me.

the following code theory could be applied to most concepts. however a couple notes, i used integer because of memory allocation and speed, so if your numbers are going to be integers obviously this is the best choice but if your going to have decimals or radicals then use double.

dim x as integer
dim y as integer
dim z as integer
x = textbox1.text
y = textbox2.text
z = x + y
textbox3.text = z

Actually, that depends on whether you are using VB6 or Vb.Net (any VB version later than VB6).

In VB6, unless you are extremely short on memory and dealing with very large arrays, the Long data type is almost always preferable to Integer. That's because being the "native" data type on the 32 bit processor, it is actually very slightly faster to process, as less conversion steps are required. (On an old 8 or 16 bit processor, or a 64 bit processor, of focurse, things will be different.)

If you are using VB.Net then I believe they have renamed the data types, so possibly Integer will again be the better way to go.

Hmm thanks killer, i wasnt aware that they changed things around like that ... damn M$ stop screwing with things :-)
