Hi jemz,
if i understand right then you have to call the keytrap function in the Keypress event of command button...
(*The keypress event you will find it by double clicking on the command button, up & right the dropdown list which its value is "Click" -> change it.)

Good luck..


hi jemz,

I assume that you are using a text box and a command button, and you have to check if the text box has only numbers , without using the key press event of the text box and by using the click event of the command button.

if so... then
you can put a loop in the on click event of the command button, using the mid function split the string in text box and check character by character if it is a number if it is not a number set some flag as false(or what ever you want), after the end of the loop if the flag is false display a message box stating that the value entered is not a valid number...

more simple way to do it is (if u dont want the ascii), use IsNumeric() function

hope this will help you
