limit characters in a string input

[dphan128]

Hi,

In LabVIEW, I'm trying to limit the number of input char entered by the operatot to 8 char. How do I set the string field to accept only 8 char and ignore the rest.

Thanks

to limit the number of input char entered by the operator to 8 char,

the simplest method would be to find number of characters by using 'string length' function. If the length is longer that 8 characters, pop up a message stating so(optional) and ingnore/reject that string

How do I set the string field to accept only 8 char and ignore the rest

To do this, use 'String subset' function, with offset=0 and length =8

A small tip.

In future, post your labVIEW related queries in LabVIEW discussion Board for a quicker response
