This is a guide to help total beginners familiarize themselves with the Visual Basic development environment.

This is an improvement on the MultiInStr function that appears in other peoples code now and again ... I don't know who the original author was, so I hope who-ever you are you don't mind ... The original code would search through a string looking for occurences of single characters, while this pair of functions search for single-or-multi character terms within the given string ... Included are MultiInStr and MultiInStrR functions ... Hope someone finds them useful ... Update 25 May - improved versions added thanks to contributions from Kenneth Buckmaster ... Update 7 Nov - Reset string len bug fix in Ken's MultiInStr ... Happy coding

Demonstrates how simple functions written in pure VB can be faster than many of VB's built in functions. For example, the super short and simple Split function is 30% faster than VB's. The Replace function with no API optimizations is 2 times faster than VB's, and over 3 times faster on large strings ... All functions are written in pure VB. Also declares the GetLocaleInfo API for use with the First Day Of The Week related functions, and for default system settings for the Formatting functions ... This would be a great learning tool for newbies. Of course, it would also be a great resourse for anyone using VB5, just plug this module into any project to enable all the VB6 functions it uses.

This VB5 program can parse large text files reading in a chunk at a time and will replace UNIX Lf chars with Windows CrLf's, or vice-versa. It uses API to boost performance and is very fast. Demonstrates finding and replacing text that crosses over the chunk boundaries - and is further complicated by the need to access the previous char to avoid replacing a Lf with CrLf if already preceded by a Cr. Uses no VB6 only functions and is just 32k compiled with no compiler optimizations. Includes word list to parse - a tiny file really at 4.5 MB but parses in a blink even in the IDE. Hope someone finds it interesting, or even useful! Happy coding, Rd :)

Extremely Fast Case-Insensitive Unicode String Array Sorting Class (Revision II) *********************************************** This string sorting class is extremely fast at case-insensitive sorting operations due to the combination of a highly optimized Blizzard quicksort algorithm, extremely fast in-place unicode comparison thanks to Ralph Eastwood, and a unique textual compare lookup table that is built only once at initialization in just over one hundredth of a second thanks to LukeH, and stored in a long array which is accessed in-line to minimize the case-conversion impact on this supremely fast comparison algorithm. Its performance on case-insensitive operations is only slightly slower than its case-sensitive binary compare operations, and is well over two times faster than StrComp's textual compare mode when used within the very same algorithm. Turning off strict compatibility with VB's StrComp function will improve performance on case-insensitive operations even further. *********************************************** Special thanks to the following for their generous contribution to this sorting class: ***************************** QuickSort Origins ~ C.A.R. Hoare ******************** String Comparison ~ Ralph Eastwood (tcm) ************* LowerCase Conversion ~ LukeH (selftaught) ************ SafeArray Substitution ~ Luke, Ralph, & Rd *********************************************** Blizzard quicksort algorithm and in-line lookup table by Rd :) *********************************************** Revision I - Fixed potential bug! Added demo project. *********************************************** Revision II - Fixed null-string descending bug!

This is a Kill Folder function with persistence ... It will remove all sub-folders and files and then optionally delete the specified folder ... I found when removing all the files in the temp folder that some locked files would fail and cause it to not continue with the rest of the files ... This function will continue to remove all unlocked files, even after finding locked files. However, if locked files are found, the parent folder will also not get removed.

Some very basic but handy tips for newbies (and maybe not so newbies). Hope you learn something. I've added quite a bit more to the article, mostly very basic info on the vb language, but we all had to learn this stuff when we started out.

This JPEG strip code is in response to a recent submission on JPEG info extraction. This code was developed by David Crowell using vb5, so don't vote. I posted it for those interested in learning more about the internals of the JPEG graphic format. Please follow Davids request to leave this zip archive intact if you re-distribute it. This is version 1, and David is still developing it, he has a freeware exe version 1.3 available at: www.ksurf.net/~bermania/prog/dessin/jpgstrip.zip I don't know whether sourse code is available.

When installing a file on an end user's machine, you should not copy an older version of the file over a new version. The InstallFile wrapper in the InstFile.bas module uses the VerFindFile and VerInstallFile API functions provided by Version.dll to copy files to the user's machine, and will not overwrite an existing file with an older version. The InstFile.bas module requires the GetVersionInfo wrapper in the VerInfo.bas module (also included) which uses several API functions also provided by Version.dll, most importantly the GetFileVersionInfo function.
