Results for "Category: String Manipulation"

These functions perform a search like InStr within a byte array. Accessing byte arrays is much faster than accessing strings, but there aren't many tools provided in VB to handle the arrays. So here you have something: InBArr and InBArrRev, which can search byte arrays with a string keyword in both Unicode and ANSI modes. *** NOTE: you probably don't have a file named C:\hotfix.txt, so you have to edit Form_Load so you can try it. *** Votes welcome :)

While I think these TrimNull functions are a bit silly business, I guess they're mostly used due to lack of understanding of Windows API return values or of the file that is being processed, here you can find proper implementations of the LTrim & RTrim equivalents for NULL characters. Instead of InStr of any kind the string is processed as Integer array, without making a new copy of the string. This allows full control over the validation process and thus string is properly parsed from any NULLs at the end or beginning of a string. A test program is included for comparison which shows the bugs in other implementations. Also a bit fuzzy logic RTrimZZ is included: it is fast, but it is mostly dedicated to cases where you expect a buffer full of NULL, except for the actual data at the beginning of the string. The functions are long but fast.

Saves time by NOT having to download your access database to Compact and Repair then re-upload again.

Used by VB applications that want to lightly (without any additional project references) transform unsafe characters into web-friendly URL Encoded text.

With this you can Read Lines (from a textbox and a string), Set Line Number, Get Line Number, Columns, etc. from a TextBox. This is very usefull, seems n00b but it isn't. Please Vote!!

Return a dataset from an excel spreadsheet using OLE DB and a "named region" as a table

This tutorial explains the ways where you can use DataAdapter directly to manipulate databases instead of writing DML commands.

This demo explains the useful functions of DataTables that help you lot while developing applications. This demo explains how to use a DataTable in various ways.. Like.. - How to initialize a DataTable - How to insert records into databases using a DataTable - How to fetch selected set of rows from a DataTable - Empty the contents of a DataTable - Clear the current structure of the DataTable - Copy rows from one DataTable to another - Use a DataTable's structure to create another - Managing changes done to a DataTable - Updating the changes made in the DataTable to the database - Make calculations on the rows of a DataTable and get results - Ways to add rows to a DataTable - Find whether the primary key column of a DataTable contains a specific value - ..etc

The passwords typed in a textbox can be read even if the * appears. But there is a way to prevent this. This is why i created this code. It prevent users from using programs like Spy to read the password (http://come.to/kobik) if the URL don't change.

Word Processor, similar to Microsoft Word (not as many features though). Different fonts, colors, sizes, tabs, rulers, images, files, find, replace, goto, word count and more. Not finished yet, if people think I should bother finishing it off I'll add undo, redo, autosave, image options and possibly more... Please leave comments. Thanks, Neophyte.

Upload and Download BLOB [files] to an Access Database. Handles any file type. Instructions included for implementation under VS.NET, WinXP, IIS 5.1 and .NET Framework SP2. Includes a class to set database connection dynamically and is almost fully documented. Not a great implementation, but does the job and provides relatively straight forward processes for providing this functionality in your WebApplication. Have Fun :)

This is a program to get the Local weather status with information provided from weather.com It is very simple and not much error proofing but it does teach you opening a webpage for reading, string manipulation and using the timer. This took me about an hour. Note it only works for US zipcodes.

This program read a xml file and stole it in a datagrid with all structure.Is a great program

This program searches an XML database for a keyword and returns the results. It uses the framework's XML classes, and a few regular expressions.

This code allows you to move items in a list box just using the mouse. Every line commented. It is very simple. I have searched high and low for a code that JUST DOES THIS without any other jargon but couldn't find any so I made it and posted it. Please give me suggestions/comments. I have edited the code to allow multi select to be enabled due to someone asking for it.

Sends your whisper messages to people on paltalk

You don't want to worry about the syntaxes of the sentences SQL, it proves with these custom sentences. Plz don`t vote for this, I upload again coz PSC remove the post when I try to update, sorry this.

Here you get 3 types of compression functions: 1) a run length encoding ("hellohellohello"->3*"hello") 2) a Huffman compression (with Huffman tree, where more frequent chars get a shorter bit string in output file) and 3) a VB interface to the ZLib compression (ZLib.dll was written by someone else). You can also compress and pack several files into one compressed file (CompressionPack) and unpack them again. Please note that my self made compression (1) and 2)) is not that fast and efficient, but good for learning purposes. If you have questions understanding the code or the basing ideas go to www.louis-coder.com and mail me!
