depends on the type of number you want. try CInt or CLng.

for the second part you could try Right$(" 29387", 3)

You can use the Val command to convert a string to a number:

Val("1234") + 5 'would = 1239

If you want to convert to a specific numeric type, use the conversion functions like;

CInt, CDec, CLng etc.

CInt("12345.6") '=12346 the fraction is rounded up on converting to an int.

what about formulas in strings?
Well, what would be a solution when you considering formulas in string. Suppose I have a string "1*2" and need the solution as an integer.. can it be done?
thanks

took a while, but here is the site for download - add the component to your project, and then you can just do something like this

Code:
Private Sub Form_Load()
Dim strFunction As String
Dim result As Variant

strFunction = "1+6*15"
result = ScriptControl1.Eval(strFunction)
MsgBox result
End Sub

...it really does display 91!

Good lord! It works!! And to think I racked my brains ripping the expression apart and assigned variables to each number and moved forth! Why, with one component its done! THANKS FISHERMAN!
