Ever wanted to extract a filename only from a path including the filename, well this simple function will do it for you! (I know its not ground breaking but its simple easy and useful)

This is not complete! it only saves in weird way. I am mostly submiting this to get feedback. I want to know if anyone has a better way to make the file it saves smaller and if anyone has a way to open it ;)

This is a file chat program that lets users chat to each other without the aid of ip addresses and winsock controls, all it needs is the location to a shared area on your network where the room files will be created then every one else enters that address in there program and then you are able to chat to each other. This program also contains static rooms that you can go to so you dont have to stay in the same room all the time. Also by the press of a button it changes into a replica of notepad in case any one comes along that might not like you chatting.It worked in my school...lol!! PLEASE TELL ME WHAT YOU THINK.

Delete a folder, with all it's subdirectories.

It protects files and folders from users.

I have seen all of these really complex GetKeyAscii functions out there. Well check this out.

Is a simple notepad like text editors with a few extra features...

This code is based upon the ONLY other VB uuencode/uudecode source code available (it's here). I put this together as part of a larger project that I'm in the middle of (a USENET binary downloader) and I wanted a uudecode routine that would decode on-the-fly. This does. It also encodes and decodes files, like a normal encoder/decoder. I spent a lot of time optimizing it, and I think it'll now decode fast enough to handle most DSL/Cable accounts on the fly (480-590 kb/s). Error checking is sparse, hopefully there's no glaring bugs. Hope it's helpful, and let me know if there's any more optimizations that you can find! [Update] I fixed the problems described below, and also replaced the static filenumbers with dynamically generated ones. Doh! [Update] Another bug found and fixed. There were null characters at the end of each line of files encoded with UUEncodeFile. They're gone now...

Ever wanted to scan a picture and save it to the Hard Drive? Well Now You Can. With a Few Lines of Code you're ready to capture a picture from a webcam or scan something from a flatbed. This may only be compatible with certain brands of scanners and webcams but should work with most. The only thing not coded by me in this sample is the control which is included. I think it was built by kodak. Anyhows enjoy. Be sure to Extract the .OCX to your Windows\System directory or most likely this will not work.

This program controls a remote unit across a range. The OFF button sends a "FF" and expects an "FF" within 1/3 of a second otherwise it times out. The reason I uploaded this is because I could not find a serial program that worked using MSCOMM and ONCOM event. I did have trouble at first until I read that Microsoft has Rthreshold default as '0'-- it needs to be '1' for the received data event to be captured I realise this is a very simple program, but it WORKS. To check this out place a wire/short between pins 2 and 3 on your DB9 serial port. This will route TX to RX on the same port. I limited it to COM1 and Com2 but others can be added. I hope this helps someone trying to use the serial port.

This code compares 2 files (EXE, BMP or whatever) using the fastest possible way in VB, only asm is faster. its about 1MB/sec. If you have problems opening the project in VB5 just remove : Retained=0 ThreadPerObject=0 MaxNumberOfThreads=1 from the projekt1.vbp using notepad (or just create a new project and add the form and the module) greets, Tom

Have you ever wanted to click a file and open it? If your program is associated with a specified file type, or you select file(s) and drag them onto the exe icon of your app then this code is for you. It reads the parameters when the form is loaded using by getting the "Command". This code can get each file dragged or clicked on. If you just use the command statement you will get something like this "c:\george.bmp c:\ben.bmp f:\mydoc.doc". This code seperates each file and uses another sub to open it.

I needed to know the size of a directory and its subdirectories (including files). Then I wanted to be able to also exclude some of the file(s) in that directory from the total directory size. So, I wrote this dll in C. You can however use it in VB as well for ease of use. Very Handy !

Copy a Folder in another Folder. If the Folder not exists then this program will create the Folder.

Get the Serialnumber from your harddisk, cd rom or your disks.

This project shows/explains all routines needed to manipulate sections/keys/values within an ini file. It has an intuitive interface, allowing to drag keys between sections, create/delete sections/keys/values, etc, but the routines can also be used individually with other projects. A must have to whom works with INI Files.

This code is designed for reading text files. i have written this code because i did not want to use the slow "open for input..." and "freefile" bla bla code... I know i coul do this via the richedit control, but i wanted to know how to do it via api, and maybe you to... This code is using the "CreateFile" Api, which must be called differently in windows 2000. Therefore, i added a "IsWin2000" function to check for windows 2000. Update: Now added a class which wraps the module, lot's of events and functionality. it's 50ms slower in read (with my test file) Class module includes also function ReadCharacters which reads the specified ammount of characters from the open file.

Listen to your exes! Write your own wav-files. This program turns any file to a wav.*-file. Learn the wav-header. Feedback please!

Well, my IGCSE mocks just finished yesterday so I was thinking what to do...so just to brush my skills (:D), I made this... We all know what the heck are INI files (if you don't, read their brief description at the bottom)...but did you know that these INI files have a size limit? YES! You see, when you call the Windows API, you will not be able to read files that are bigger than 10kb (on win 9.x i think...correct me if I am wrong) and 64kb on win me/nt/2k. So the next time you try to read a value that is held in position after the 64k/10k mark on a file, all u'll get is a blank (you can do the GetLastError API to see what error was, never tried it though). But HO HO! (look who comes to the rescue) During the past 1 and a half hours (or something), I just wrote a class that will read INI's all by opening them for input and output, and ofcourse, parsing them on their way. So now, throw away ur existing API INI classes and replace these. Features: 1. No more INI File size limit 2. Useful for writing file formats. Yes! For example, I previously wrote an INI script format(crazy idea, huh?) in which some values of keys were actually the names of other keys and in this way, a flow of data can be formed that doesn't have to follow hard-coded format. 3. As fast (well, almost....now, reading a teeny weeny value from a 500kb file that contained 50,000 items took 5 seconds or something on my computer...btw, the file was generated to test the class. Also, there is hardly any noticeable difference between the API and this class even if the file is smaller than 64k). 4. Other features that were included were: Read/Write value (basic INI I/O), Delete a key, Delete the whole darn Section, get all sections (only sectionsuseful for enumerating...file formats!), get all keys with their values all together (useful for enumerating...again file formats!), write values all at once from an array (instead of doing them one by one, which may get slow). 5. It's a drop-in class...just drop and use! very easy parameters to follow :) WHAT INIs ARE: INIs came along with the advent of Windows OSes. They were initially (and, well, still are) are used for storing settings of a program. You can say INI is a standard file format for saving settings (I say standard when I mean Windows standard). Windows supplies APIs that make it easy for us, the developers, to read and write values using just plain strings, which the Windows APIs organises into a format in a file. The format is: 1. There is a section that represents a number of keys (both of which you set) 2. There are keys that represent values (you set the values too) 3. Then there are other sections, 4. with other keys, 5. with other values. 6. blah blah and oh ya, I didn't do an example cuz I think almost everyone might have come across INI files (and anyway, it will take only 3 lines max to write a value to a file using this class) (vote if you like :D...I dont mind, nor do I bite...so criticism [not in a harsh way, mind you] may be appreciated.) Tata!

Here you can make a new folder with just ONE line of code. You decide where you wanna place the folder(like 'c:\New Folder\Sub\'). You don't need any extra OCX's or other kind of controls so just take the code and enjoy it. The code is very useful to me and im sure it will be to you too. /Author
