This is a collection of highly requested Visual Basic code that I put together back in 1998 and 1999. Almost all of these samples will work on fine on Visual Basic 5.0 and for Microsoft Excel and Microsoft Access Programming (when done with VBA), however, I've only made sure that they work in VB6. Back in the day I used to answer a lot of questions and I frequented a lot of VB message boards. I noticed that the same questions kept getting asked over and over again, so I started saving code that seemed to be important. 95% of the code you'll find on this page was written by me, the other samples were either edited or submitted. This guide does not claim to have the best answers, just answers that will get the job done. I hope you find it helpful.
If you aren't able to find what you need here, you can check out the main programming section for additional VB 6.0 code and tutorials.

This code shows you how to add a menu to another program.The only thing is that nothing will happen when you click on the items. To make something happen when you click on an item you have to subclass the menu (I'd help with that but I don't have any subclassing controls, or at least not right now). Put this in your *.bas file:
Then put something like this in a button:
This shows you how to set the frequency & duration of a beep sound. Put this in your *.bas file1:53 AM 8/19/2007:
Put something like this in a button:
Or, if you want to do something a little more fun, try this:
Here's how to center a form so it will appear in the middle of the screen, put this in a button:
Here's how to convert old 16 bit VB froms into 32 bit VB forms: In a 16 bit version of VB (like VB3), select 'File' from the menu, then click on 'Save File As...' A dialog box will pop up. Look for a checkbox on that dialog box that says 'Save as Text.' Make sure that is checked. Once you do that, save the file. You should now be able to use that form in 32 bit versions of VB (like VB6).
This code will count how many lines of text there are in a string by counting the number of times the'carriage return' character shows up and adding one to that. This code will not count lines of text that wrap in a textbox. Put this code in a button:
This code shows you how to count the number of times your program is used. Place this function in your *.bas file:
Example on how to use this function, put something like this in the form load event:
This code lets you count the number of words that are in a textbox (note this is very different from the len function which counts the number of characters in a string). Put these two functions in your *.bas file:
Then put something like this in a button:

Below is an example of a substitution cipher. Substitution ciphers can be broken by a cryptanalyst who knows what they're doing, so this method of encryption shouldn't beused if you want your data to be 99% secure. However, substitution ciphers will keep common users from being able to seeyour data. For high levels of security look into public key encryption andAES.To continue on, copy and paste the function below into your *.bas file:
How to use this function:
To encrypt a word just put something like this in a button:
And then to unencrypt the word just call the function again!
This code demonstrates a fast way to flip a picture in a picturebox horizontally or vertically. Put this in your *.bas file:
Then put something like this in a button:

Put this code in the label's MouseMove event:
This is an example that shows you how to get the html color value (ie, the hex value) of a color. You will need to add theMicrosoft Common Dialog control to your project for this to work. Put this code in a button:
Did you ever want to know what your computer's name was? Not me, but anyway, if you do want to know try this... Put this code in your *.bas file:
Then put something like this in a button:
Ok, this example code will show you how to open up an exe, copy it, replace strings in the copy with strings of your choice, and then make a new program with the new strings in it.
For this to work you need to have two textboxes on a form (named: txtProgInput and txtProgOutput) and two lists (named lstOldStrings and lstNewStrings). txtProgInput contains the name of program you're editing (like:'C:somefile.exe') and txtProgOutput contains the name of the program you're making from this program. lstOldStrings contains a list of strings your replacing and lstNewStrings contains the list of what you're replacing them with. IMPORTANT NOTE: The length of the string you're replacing must be the same as the length of the string you're replacing it with, otherwise you'll get an error. Put this code in a button:
HTML color values are stored in a hexadecimal format. Each HTML color value is divided into 3 parts: the color's amount of red, green, & blue - #FF0000. The amount of red a color can have is in the range of 0 to 255 (same goes for green & blue). So if you have 255 for red and20 for blue and green, your color will be sort of redish looking.
Anyway, the following is an example on how to fade one color into another. Put this function in your *.bas file:
Then put something like this in a button:
This example shows you how to create a fade preview of color faded text inside of a picturebox. You will need to add a picturebox control named 'Picture1' to your form for this to work.Put this code in a button:
Just like the title says. Put this code in a button:

This shows you how to put an icon in the system tray. It uses an icon stored in Picture1.picture as the icon.Put this in your *.bas file:
Then put something like this in a button to add the icon to the tray:
Put something like this in a button to remove the icon:
This code loops though a list (List1) checking each item with every other item, then when it finds a duplicate it removes it. Put this code in a button:
Here's another way to do it, this way is somewhat faster and uses some Windows API functions (sentin by Sopon). First put this in your *.bas file:

AOL Macro Fonts allowed you to type in large ASCII art text, like you see below.
|¯¯¯-¯)::)¯¯,¯_':|¯¯¯¯¯¯¯||:|__|¯|°:/__/'__:|¯¯|__|¯¯|
::|__|¯::|__:|/|__|':¯¯|__|¯¯
This code example shows you how to create a macro font feature for a Macro Shop / ASCII Art Shop program. It makes it so you can select a (*.pmf) file (a sample pmf file can be downloaded here), load it into a 2D array, and thenhave the output display when the user types text in an input textbox. You will need the followingfor this example to work:
txtInput - An input textbox named 'txtInput'. This is where the user types their input.
txtOutput - An output textbox named 'txtOutput'. This is where the output is displayed. This textboxshould have it's multiline property set to true and it's font type set to 'Arial' and point size set to 10.
CommonDialog1 - A common dialog control should be added to the project.
Put something like this in your *.bas file:
Put something like this in the load a font button:
And then put something like this in the Change event of txtInput:
This shows you how to open your default browser. Put this function in your *.bas file:
Then put something like this in a button:

Here's what you do to make a screen saver: Start a new project. Set the windowstate property of the form to '2 - Maximized', and the border style of the form to zero. In the 'KeyDown' event of the form put the 'End' statement. Then in the mouse move event of the form put something like this:
Now select 'Make some_project_name.exe' in the file menu. When it asks you what you want to name the exe, add a '*.scr' extension to the end of the name (example: Blah.src). Then select the directory 'c:windowssystem' as the place to make this program. And there you go, you've made a screensaver which you can use on your desktop (note: you'll probably want to jazz up the form a little bit first).
Additional Info: (Provided by Mike Clem)
Try adding 'SCRNSAVE: ' in front of the name of your screen saver when compiling if you cannot get Windows to recognize that your creation is a screen saver. Example: 'SCRNSAVE: Blah.SCR'
Problem of Windows not recognizing the Screen Saver occured in WFW 3.11 using VB 3.0.

Here's how to give VB5/6 the VB3 interface: Select 'Tools'>'Options' from the menu. Then when the 'Options' form pops up select the 'Advanced' tab. Make sure the 'SDI Development Environment' checkbox is checked, and click 'OK'. When you restart VB5/6, you should have the same kind of interface that you had with VB3.
