Character Verification 追蹤
I have created a data entry form and have been successful in controlling the characters and qty of characters and now I would like to take it one step further. I would like the application to verify the data that is input. If the first character isn't a "4" then it would give and error, if the third wasn't a "1" and then it would give an error. I'm sure with some VB skills this would be no problem, however I lack those skills so it will be starting from the basics to learn. I'm hoping there is another field I missed that could control this. Thanks for the help.
