Checking Format VB2005

[davebaty]

I have a text box in vb2005 where text needs to be entered in a certain format eg. a time hh:mm or another with just four characters. I want the backcolor of the box to change color if the format is not correct. However, I am having difficulties checking the formats of each box. How can this be done? I am currently trying code in the 'TextChanged' event, but not getting anywhere.

Many Thanks,

Dave.

Instead of textbox, why don't you use maskedtextbox?
