Results for "Category: String Manipulation"

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!

ClsExtendedRTF.Cls version 3 for RichTextBox extensive rewrite, recode and rename. Mostly about manipulating RTF code to change text and background colours. Now includes API and RTF based higlighting(Not selection, this is the RichTextBox equivalant of highlihter pens). Highlighting with: API advantage it can detect highlighting; disadvantage single colour at a time RTF advantage multicolour highlighting. disadvantage can't detect itself. ClsAPIZoom for RichTtextBox, a few lines of code and your RTBox is zoomable. cLsManifestation (incorperated from my other upload) Gives compiled program user's choice of Classic or WindowsXP(if they have XP) added panels(form) which give you greater control over highlight, text colour and text format. *New* Materials interface you can create your own materials colour schemes. *New* Styles; if you create a text and background colour scheme you want to reuse save it with a name and access through the RTF Font Painter tool and class. fixed small bug in RemoveFormatting which added a space to start;(if selection was at start of doc) see earlier versions for mor details.

Function that counts the occurrance of a given phrase in a larger string. (I needed this function and couldn't find anything like it in MSDN for VB)

Ever wanted the ability to run a 'smart' search, ie, with full and's, or's, not's, xor's, brackets (even nested brackets), and "". Basically like a search engine? This is the vb code to do it for you. An example expression would be: animals and ((cats or feline) or (dogs or canine)) and "is cuddly" Very usefull and very easy to implement

After looking here and a few other places for a simple code that allows only numerals and not to allow text to be pasted into a textbox and with no prevail I figured it out. Not a major thing but for beginners this will help them.

This is a recursive function to calculate a string formula. For example: You have a formula like "3*((2+6)*2-2)/(2+2)". You just call the function to get the answer. Hope this is useful to somebody:)
