Results for "Category: String Manipulation"

This is a .bas module that contains a few string manipulation functions I find useful in the real word. MakeProper replaces the limited proper case functions of VB with code that will format your string in title case, but not force mid-word capital letters to lower case. So "John Smith III" or "MacDonald" comes out correctly if typed are typed as "john smith III" or "macDonald". Initial letters of words are capitalized, but other letters are left as typed. DateWord takes a date and converts it to the phrasing used on legal documents, so 1/1/2000 would return "1st day of January, 2000." MailingLabelText accepts a number of inputs and returns a UDT that offers many variations on the name and address for use in creating mailing labels and other reports containing name and address data. The proper business ettiquette is observed in that the presence of an honorific like "Esquire or MD" eliminates the "Mr." or "Dr." Look for an update of this soon with more functions for string manipulation. The other functions are used by these three. LogError is pretty useful, too, come to think of it! I don't care about winning any prizes, I just wanted to contribute to a site that has helped me out so much. Your feedback is welcome all the same. PLEASE STILL RATE THIS SO I WILL KNOW WHAT YOU THINK!

That's right, all positive long values up to 2147483647. This simple algorithm can translate any positive long value to its string equivalent, both English and Spanish. The principle is simple: Process three digits at a time because the cycle is repetitive every three digits. The only thing you have to append every time is the order qualifier: Thousand, Million, or Billion. The code of the main function is commented, and the other functions are just plain very easy, so no commenting there. The user interface shown here is very simple because the object of this post is the functionality! :) BONUS: Included (and made just for fun) there is a custom uppercase function. It was programmed under the principle that switching between lower and upper case, all you have to do is flip bit &H20. It also writes to the source string directly by mapping an array to the string buffer (advanced stuff). I did not benchmark, but supposedly, this upper case method should be a lot faster than regular string manipulation, although I don't know if it is faster than the VB upper case function. If you want to implement this in one of your applications, all you have to do is drop the module in. Please vote and comment. UPDATE: Run-time error 9 in uppercase function solved. It was a silly error.

This VERY short function compares 2 strings and returns a number (that can be converted into percentage if multiplied by 100) that represents how closely related 2 strings are. For instance "ABCDE" and "ABCDF" would return say.... .8 (80%). Great for suggesting fixes for spelling errors et cetera. Feel free to use, abuse, and manipulate the code however you want, I'm sure it's not original, but I know it can be helpful :).

Adds the text to a textbox, checking for length overflow. First, it checks, and if the textbox exceeds 15,000 characters, it strips out all but the last 2000 characters to make room for the new text. It doesn't break in the middle of lines - it only deletes 'whole lines.' Then it adds the text to the end, using the color you specified (if any), and scrolls to the end of the textbox. I use it all the time, got tired of cutting/pasting out of old projects, thought I'd put it here on PSC.

Very simple, almost useless code! Shows all "printable" ASCII characters. I needed this for something else, so I thought I'd post it here for beginners' benefit

A textbox for TCP/IP or DNS entry with validation and formatting. It behaves like Windows TCP/IP entry. Very nice in developing program that requires valid IP entry.

This example I put together teaches you how to use the InStr function with a string. InStr is very important to use because you can get certain information from a String by using it. Example: say a String has your first and last name in it like "Mike Canejo". InStr allows you to get just the last name or first name. First and Last name are just an example. You could do tons of things with Instr. This is very important for a beginner to know trust me. You'll be surprized if you end up using it in your next vb project :)

This small and very simple sub will format the caption of a Label control if the text is too big to display in the control. The sub will trucate the text and append "..." to the end of the text (indicating to the user that they are not seeing the full text). VB automatically wordwraps the caption of a label if it is too big, however, this results in the caption being truncated only where there is a space. Also, you can see the top of the next line of the caption. Example Make and Model: Cadillac becomes: Make and Model: Cadillac Eldor... I find this extremely useful when I don't know the maximum length of the text the label will contain, or if I don't have enough screen real estate to make the Label big enough. Just pass a label to this sub for formatting.

This code provides an IsNull function like that used in SQL Server. This allows you to check if a variable contains null, and if so return a specific value. This can prevent you from having to write things like iif(not isnull(rst!FieldName), rst!FieldName, ""). For new programmers, especially those working with databases, you will quickly become aware that trying to access a database field that contains a null value often results in the dreaded error #94 - Invalid Use of Null, which means you constantly have to write code to trap for that possibility.

This is an incredible program that lets you generate encrypted self-decrypting HTML files! It converts RichText to encrypted self-decrypting HTML files! Just type in your message in RichText format, choose a Password, and it automatically encrypts your message and generate that self-decrypting HTML file. Cool! How do you get the files decrypted? Simply with any IE browser, open it, type your Password, and you'll have the message automatically decrypted!

This is a recursive function that evaluates strings expressions. It supports multiple levels of parenthesis, algebraic evaluation of expressions (in this example exponentiation ^ has same level of multiplication and division), function calls, logical operators, string/date/numeric functions and expresion evaluation. This is the base for the creation of a scripting language.

I needed a routine to display the difference between two dates in year month day format. I found a couple here on pcs and another on a different site. Here is a project to call the three routines and display their results side by side. In case your wondering about Datediff it returns the number of times the year, month or whatever has changed between the two date. i.e. it returns 1 when from is dec 31 yyyy and to is jan 1 yyyy+1. Anyway here are three routines, two of them worked in all the test conditions I tried, the other gets a wild hair up it rear every once in a while. Louis Boldt 2/16/02

The Most difficult Thing in VB..How to Get UNICODE From Pointer Of Ansi String..

The purpose of this article is to teach the reader how to split a string into fragments and use the fragments effectively. Useful for Winsock programs, date commands, and other possible needs.

Paste the contents of a plaintext document into the main multiline text box, click "Parse," and this program creates an array for each unique word and the frequency at which the word occurs in the string. I made this to check my own writing for over-used words; if you're a writer you may notice how you tend to use the same words over and over again; in conjunction with a thesaurus this could be a powerful tool to liven up your use of vocabulary.

Ever too tired to control user's input? Ever want to control maxlength of a combobox? Ever want to validate and correct and hint(optional) user's input automatically? This is what you need to control user's input with textbox, combox etc. I am working on it and have figured out many improvements that can be done if you are so kind to rate it! Any comment or vote is appreciated! Please vote for it if you guys desire a much better version :-)

Regular Expressions - match strings. *,+,?,[0-9],[A-Z], read note on the initial form code. Requires a reference to vbscript.dll. Only works in VB6.

FormatFileSize: Formats a file's size in bytes into X GB or X MB or X KB or X bytes depending on size (a la Win9x Properties tab) * UPDATED Sept. 12, 2000 * to allow for overriding the default Format Mask.

This code should explain the bubble sort ! Bubble sort is a sort algorithm that sortes string in very fast way. There are many sort algorithms but this is the best !

(PLEASE ALSO LOOK AT VERSION 2.10!)This code is an example of 13 different FX that can be easily implemented to a string. I have put them all together and put in quite a few notes explaining what each FX is doing. As you can see from the screenshot each effect can be modified in certain ways. I have written this so that you can have a better understanding of how computers work. I have tried to avoid using many of the built in functions. Each FX may not be the most efficient way of doing them, but I have done it this way to highlight the internal workings. All FX (apart from Rotate) work at a character at a time. Please send in any comments you may have - Good or Bad - so I can improve on it further. If you have any questions then email me. PLEASE RATE THIS. Thankyou.
