tis is a simplest way of validating user input. Yust open the project and press F5... check TAG properti in text boxes... You can program validation in RUN TIME or at DEVELOPMENT TIME...

This is in response to a question on posted on the Programming Q & A section. It takes a string and fills a listbox with all combinations of the letters in the string (could be adapted to use a dynamic array, too, the listbox was better for demonstration purposes). This program use recursion to get it's results and may be a good example for someone learning the concept to step through. Warning: The number of combinations goes up exponentially! more than 8 characters will work but really bog down your PC!

I know there is the replace(text1.text,"Jack","Jill") in VB6 which would find all the words Jack and replace them with Jill in text1, but how can I do this in VB5? I want to be able to put symbols in general sentences, and replace the symbols with specific data. such as: Thats a great pass from #! He passes to # who sets up a shot!

Changed the interface a bit, made the labels for the menus into textboxes so they can go *over* the rich text box, thus letting me make it bigger. Added the ability to password protect the program, (the password is encrypted then flipped backwards), and there is now a "QuickCrypt" function that lets you select a file, encrypt it, then save it, without using the open then save and so on options from the menus. Still trying to figure out compression! If you have any idea on how I could get a *nice* way of compression for ALL 255 characters, aside from using the zlib dll, tell me! If you have not seen the other version of this program, 2.2, this program encrypts all 255 characters in a decently strong way. Oh, also added the small part to see that time it took to encrypt the file, it slows down the process though!

This program search a string in multiple documents at the same time and lets you open the match documents from the program. I`ve had add some new features like select the extension of documentes, view only the 10 first matches and save the configuration to use in another sesion. I`ve fixed the program for this usefull version. Thank yours for this chance.

I wrote this code to learn a little bit about string manipulation. Although I will deffinatly not claim it's uncrackable, it is deffinatly a little less bulky than some of the others. Not to mention since i submited the code anyone could just use the decryption on it. But anyway, it may be of some help, although I will admit it's a bit slow with large files. I am trying to find ways to improve it's speed. Any ideas are welcome.

I was recieving several requests after recently making a post concerning a scrolling credits examples, simply saying that I had something similiar that worked in most aspects slightly better, because it used BitBlt and read the credits directly from a text file. I got quite a few emails requesting I send them it, so I just decided to post it to this site. Hope everyone likes it, if not sorry.

I keep reading requests for RichtextBox code on PSC so I decided to upload one of my templates with a few added features. Nothing that special here really - basic RichtextBox functioality. The RichtextBox is pretty good at what it does though ! This example demonstrates : Find and Replace, Infinite Undo/Redo, Using .tmp files, HighLighting selected words, Inserting Images, Inserting text at a set location with different Fonts, Common Editing Functions, Shrinking a path to a desired length, Creating your own light-weight Wizard. This is not meant to be a complete application merely a demonstation of some techniques. All error messages and bugs are provided entirely free of charge. Feel free to use any of the code or errors as you wish - MS wrote the control - I've just shown how you might use it. It's capable of more than I've shown here.

Simple function to validate string contents. Compares a given string to a list of illegal values and evaluates whether or not it contains any. Very fast and easy. Can also be used as a string search function with a little modification.

Explores and teaches parsing algorithm techniques (PART 1)

When called with a string, will search through the string and replace a character of your choice with another character of your choice. For example, if you sent the string: "Hello to the world" And sent "o" as the character to be replaced, and sent "a" as the replacement It will return you with: "Hella ta the warld".

This function will strip a string of all html. An optional parameter (sIgnoreTags) allows specified HTML tags to be ignored from stripping.

ClsExtendedRTF Version 2a OOPS SMALL UPGRADE FORGOT ABOUT LOW RESOLUTION SCREENS sort of fixed that and there's a small animation demo added as an apology. This code manipulates the underlying Rich Text format string in RichTextBoxes in several ways. Highlight text, add interesting, strange and weird formats to RTF text. Resize mixed sizes of fonts with one call. Add a Zooming ComboBox to any RichTextBox. CommonDialog is encapsulated to give File New / Open / Save / SaveAs / SafeSave and Reload functionality. ShowColor is also encapsulated. This is a more stable version of this code. Insertion point is preserved after changes to text. More of the work is done at string manipulation level. New details added see * below for version 2's new elements. Minimum Requirments Riched20.dll (version 3) Riched32.dll (5.00.2008.1) probably the Richx32.ocx control Highlight now comes in two flavours RTF and API there are advantages and disadvatages to each. Menu and Toolbar use API; Text Colour Panel (in Font Looks menu) uses RTF Incorperated my ClsManifestation (see help) It is behind the spanner button on the tool bar only useful in WindowsXP to choose between XP and Classic look for compiled demo. Does not work in IDE. Font Looks menu contains to Forms which can be added to other programs to give maximum freedom of using the Font format and colour options. Added new font colour choices. Improved Demo performance. Corrected many minor bugs(extra spaces, spaces being deleted) Added Zoom ability Broke up the original ClsExtendedRTF into a couple of separate classes. Rewrote, simplified and often renamed routines for speed and comprehension Please comment, vote and send me interesting formats you develop and I'll included them with acknowlegments. Feel free to take just the parts you want (leave copyrights etc) this class is still 'Under Construction' if you like check back for updates. Demo Program is also a test bed for experimenting with RTF. 'ExtendedRTF Code for VB6.rtf'is both the help file and the demonstation file and was created interactivly with the code. NOTE uses VB6 only routines but if you have work-rounds for them should work with VB5, VB4. Needs more recent versions of RichText control. ExtendedRTF provides: 1. Highlight (NOT the same as select) *more ways of accessing this facility. 2.Other Underlines wave,dot,dash, dashdot, dashdotdot, hairline, and thick. (word and double are partially supported; you can set them but they appear as single in RichTextBox, in Word they look fine) 3. Hidden text/images 4. Weird font formats. Ripple, HeightRipple, Ransom 5.Font colour schemes *Rainbow, *Spectrum and *Materials. 6.subscript, superscript,up and down RTF codes. RichTextBox recognises '\up' and '\dn' with as superscript but not '\sub' and '\super' ???? 7. Get current insertion point as percentage of total document 8. Remove excess spaces in selection or whole document. 9. File handling: routines to simplify standard New/Open/Save/SaveAs. *Reload routine reload last saved document without opening CommonDialog *Document loaded in IDE is automatically reloaded from disk. SafeSave routine place this in your exit program and file procedures and you'll never lose your edits again.

This code shows you how to create nearly Unlimited Undos and Unlimited Redos, along with Cut Copy, Paste, and Select All features, in a RichTextBox Control. This code was originally programmed by Jason Shimkoski, it was updated by me when I discovered an error in his program.

Checks to make sure the contents of a TextBox or String are only standard ASCII; If it has any extended ASCII, the function will return False.

This one-line function returns whether or not a string consists of only the characters A-Z, a-z, and 0-9.

This will create the 8 or 9 digit number that goes along with the log on packet for the newest version of the AIM TOC Protocol (version 2.0). The number that it makes, is based on the screen name and password. I guess it was a security feature added in, to prevent users from making AIM Crackers.

Lots of different function for handling VB strings. Take a look inside, you mightlike what you see...

This code is the first posted on Planet-Source-Code to do more than just ADD and GET INFO from INI files. You can now also DELETE Keys, Values, EVEN SECTIONS. I am working to create functions to rename sections and keys also. Enjoy this code! Fully explained!

This is a simple example of converting a string data into a hex formatted (packet) view. This will be mostly usefull when sending and receiving data with/through WinSock! Packet displays data in hex and 'readable' characters like the packet below, which seems to be the text you're reading right at this time! 48 65 6C 6C 6F 2C 0D 0A 0D 0A 54 68 69 73 20 69 Hello,....This.i 73 20 61 6E 20 65 78 61 6D 70 6C 65 20 6F 66 20 s.an.example.of. 63 6F 6E 76 65 72 74 69 6E 67 20 61 20 73 74 72 converting.a.str 69 6E 67 20 64 61 74 61 20 69 6E 74 6F 20 61 20 ing.data.into.a. 68 65 78 20 66 6F 72 6D 61 74 74 65 64 20 28 70 hex.formatted.(p 61 63 6B 65 74 29 20 76 69 65 77 2E 0D 0A 54 68 acket).view...Th 69 73 20 77 69 6C 6C 20 62 65 20 6D 6F 73 74 6C is.will.be.mostl 79 20 75 73 65 66 75 6C 6C 20 77 68 65 6E 20 73 y.usefull.when.s 65 6E 64 69 6E 67 20 61 6E 64 20 72 65 63 65 69 ending.and.recei 76 69 6E 67 20 64 61 74 61 20 77 69 74 68 2F 74 ving.data.with/t 68 72 6F 75 67 68 20 57 69 6E 53 6F 63 6B 21 0D hrough.WinSock!. 0A 0D 0A 50 61 63 6B 65 74 20 64 69 73 70 6C 61 ...Packet.displa 79 73 20 64 61 74 61 20 69 6E 20 68 65 78 20 61 ys.data.in.hex.a 6E 64 20 27 72 65 61 64 61 62 6C 65 27 20 63 68 nd.'readable'.ch 61 72 61 63 74 65 72 73 20 6C 69 6B 65 20 74 68 aracters.like.th 65 20 70 61 63 6B 65 74 20 62 65 6C 6F 77 2C 0D e.packet.below,. 0A 77 68 69 63 68 20 73 65 65 6D 73 20 74 6F 20 .which.seems.to. 62 65 20 74 68 65 20 74 65 78 74 20 79 6F 75 27 be.the.text.you' 72 65 20 72 65 61 64 69 6E 67 20 72 69 67 68 74 re.reading.right 20 61 74 20 74 68 69 73 20 74 69 6D 65 21 .at.this.time!
