When a user presses the Cancel button, the control that previously had focus triggers its LostFocus event, which is where many programs do their validity checking. If the input wasn’t

Rather than using Visual Basic’s line and shape objects when drawing complex graphic backgrounds on forms, use the MS Draw applet included with most Microsoft products to draw a Windows

One problem that occurs frequently is taking the menu structure from one form and placing it in another. Although my method of dealing with this dilemma requires a little effort,

Suppose you have two list boxes side by side-one to display the name of a person, the other to display his or her e-mail address. If the boxes contain several

I have seen many posters in the VB newsgroups that say they have received an ODBC error message such as 3146, but can’t figure out why they got the message.

Sometimes it is useful to set a cursor to determine control when a form is loading-after the form is done loading, the cursor stays on the control you have ordered:

To synchronously shell an application from a 16-bit VB application, some people write code like this: Const HINSTANCE_ERROR% = 32Dim hInstChild As Integer’Shell program, if Shell worked, enter loophInstChild =

I have developed this technique to use when I program long formulas. First, I declare descriptive variables for the mathematical elements. I prototype the formula using the digit “1” as
