What is the code in vb for enabling focus on certain objects like textboes, datetimepickers, or combo boxes until certain condition are met. Let's say,

Textbox A has the number "11", but the condition was if >= 10, then a messagebox will prompt user, followed by the user are unable to select other textboxes or buttons until the condition is met.

Is this possible in Visual BASIC? If so, how do we enable this function.

Is this VB.NET, or VB6 ? In VB.NET the control has a Focus() method. Call that to put the focus back and check in the focus lost event, that way, the focus will go back there until they enter an OK value. Which is bad UI, really, your textbox should ideally only accept values in the correct range, and if the user can only enter 1-10, for example, a drop box is better UI.

I'm using Windows Form Application on Visual Studio 2008. Doesn't that mean i'm on Visual BASIC not VB.net or vb6? i'm uncertain as well.

You're using VB.NET.
