Creating customizable alert boxes using VBScript

No, we're not stabbing JavaScript in the back...just having a little harmless fun in this tutorial. The entertainment? Customizable alert boxes.

In JavaScript, alert boxes are as simplistic- and dull- as they come:

alert("Hello there")

Apart from the message itself, nothing is changeable in terms of the box's interface. Where JavaScript skims through, VBScript dwells on, however. Alert boxes called using the later language can be customized in ways that the former can only dream of.

A basic alert box in VBScript is produced using the following code:

<script language="VBScript">
MsgBox "Hello there"

From this point on, however, things take on a life of its own, thanks to the optional parameters the above method supports. Case in point:

MsgBox "Hello there",64,"Greetings From JK"

Note the differing icon image to the left of the message, not to mention the title on top!

The below tables contain the supported values for the second parameter of MsgBox, which we'll show first, then explain how to use:

'Which buttons" Table:

Constant Rendered button(s)
0 "Ok" button
1 "Ok" AND "Cancel" buttons
2 "Abort", 'Retry", AND "Ignore" buttons
3 "Yes", 'No", AND "Cancel" buttons
4 "Yes" AND "No" button
5 "Retry" AND "Cancel" button

Default button table:

Constant Rendered button(s)
0 The first button from the left is the default button
256 The second button from the left is the default button
512 The third button from the left is the default button
768 The fourth button from the left is the default button

Icon image table:

Constant Rendered image

The above constants are interconnected and inseparable in their use. To specify which buttons and icons to equip your VB Alert box with, add up the relevant constant in each table (in total three constants), producing the parameter. Huh? For example, the box:

alert2.gif (3332 bytes)

was produced using the parameter 0+0+64=64, since we wanted just an "Ok" button, that it be the default one, and lastly, have the "exclamation" icon image shown.

Making sure the message is across, here's another VB box, rendered using:

MsgBox "Incorrect",37,"Greetings From JK"

5+0+32 is where the 37 was derived from.
