VB 6 - Useful Vb Functions

[Pino]

IsNumeric()

This function returns true if the selected item is Numberic (Numbers) and false if it is not.

Use -

IsNumeric([Expression]) as boolean

[Expression] Would be the item you were looking to see if it was numeric.

Example -

If IsNumeric("78906") = True Then
    MsgBox ("True")
End If
 
'The above statement would return the true msgbox
 
If IsNumeric("5566pp578") = True Then
      MsgBox ("true")
End If
 
' This statement would not because the string we specified contains characters "pp"

So this function returns true if a specified expresion is numerical and flase if it is not

Note - It does also work for decimals so 0.8950 would return true
