Question about using strings

[Gazza_H]

Hi

I've got a simple calculator program which uses strings to contain the numbers entered as well as the answer. The problem I have is I can't perform any mathematical calulations with them. For example with the code I used to add the two numbers i.e. 2, 1 they donot add together they just combine so instead of getting the answer 3 I get 21. What am I doing wrong?

You must use:

yourstring = 1 + 2

Not:

yourstring = 1 & 2

Hope This Helps...

Use the Val function.

Dim str1 As String
Dim str2 As String
 
str1 = "1"
str2 = "2"
 
MsgBox Val(str1) + Val(str2)

Best regards
