Make a standard command button very flat ;-)

Example

A little set of routines and a test driver to read table or array properties: whether it is (re)dimensioned or still undimensioned, the number of dimensions, LBound and UBound for each dimension and a few other things that may come in handy. No fuss about skipping around Errors or such, just the proper way to do it.

This is a little cat which yearns for the mouse - at least it follows it with the eyes all the time. You can drag it anywhere you like, and it goes away when you doubleclick it. Try it, download is only five kB.

This is a normal Message Box, but with a timer which will make it disappear after a certain amount of time. The return value depends on whether the user clicked one of the buttons (when the normal MsgBox return values are handed back) or whether the box was closed automatically - in this case a zero is returned.

This project shows how you can intercept GPFs. Instead of crashing your application in case of a GPF, a PopUp is openend showing error details and giving the user the choice between continuing the buggy application or terminating it in a neat and proper way. (This is based on a previous submission. Tested on WinXP only.)

This demo application demonstrates the use of a Custom Tooltip Class supporting square and ballon style tooltips, centered at the corresponding control or at the mouse pointer hot spot, with or without title. Individual back- and forecolors and fonts are also possible as well as an assortment of Icons to be displayed in the tooltip and finally individual delay- and show-times. And whats more - the tooltip can now speak using Microsoft's Speech Object Library (SpVoice in sapi.dll), no XVoice.dll or VText.dll! The code is easy to follow and well documented. And on top of that the class is very easy to use. Check it out, download is only 10 kB.

Demonstrates the use of a property bag to store "things" in a file in any order and to retrieve those things from that file in any order. "Things" include strings, numerics, results of arithmetic or string operations, booleans, fonts and even pictures.

Remember the old days when the Black Avenger of the Spanish Main (alias Tom Sawyer) roamed the Carribean Seas and spread terror among his foes? Well, this is what went overboard one day and you are the lucky one to find it.

This creates a triangulated terrain model from samples taken in the real world. Samples consist of x-, y-, and z-coordinates taken at arbitrary points in the terrain during a survey on site or during a satelite or airborne radar survey. The project shows several methods and techniques regarding trigonometry, maths, and transforming/projecting 3D entities onto a 2D drawing canvas. Some documentation and the basic theory about the triangulation process is included. Download is 77kB.

In one line - well, with a little cheating ;-)

This little code snippet returns a truly random sequence of Rnd's

Very fast integer sorter. Using 1800 MHz Athlon processor will sort ten million integers in just over three seconds. (see http://www.Planet-Source-Code.com/vb/scripts/ShowCode.asp?txtCodeId=59491&lngWId=1)

The trouble with VB's own Recent Projects List is that it is untidy and unsorted, it grows until you can't find anything, it does not remove broken links, and last but not least the window is way to small to display long pathes. So what we need is a little helper to tidy up and sort VB's Recent Projects List. And wouldn't it be nice if you could launch VB with an open project inside it right from the beginning? Well, try this one - download is 24.5 kB. (See ReadMe.txt)

How to securely exchange encryption keys over unsecure lines.

Would you believe that the sizing grabber - that is the little triangle in the bottom right hand corner - is in fact disguised a scroll bar? Well, have a look...

With the InputBox you cannot distinguish between the cases a:- Cancel clicked b:- nothing entered and OK clicked because in both cases the returned string is a vbNullString There is a simple trick however as is shown here

Class to create an irregular shaped form from a picture. The screen shot sample shows an MM-shaped form and the ears, the black circle and the button make up the form. The remainder inside the circle does not belong to the form.

This AddIn compares the source code in the VB IDE with the source code that was last saved and shows the differences. If you have been working on a piece of code for a while you can probably not remember all you have done. One click - and this AddIn will tell you. Alterations to the form or to controls in that form are also shown. The comparison is not line number dependent but is controlled by content only. Unaltered lines are shown in black, new lines in red, deleted lines are blue and striken out, and finally changed lines are shown as deleted and new. Empty lines which you might have inserted or deleted are not shown - this is because I found it rather difficult to strike out nothing *g*

Shows how to rotate the orientation of True Type fonts
