Hi folks, Well, there seems to be little interest in the subject. Either that, or I wasn't very clear on what I wanted - or, few people had what to say of instructive on the matter. No matter the case, in case anyone is looking for a solution, here is what I've found: There is, amongst other things, a good article online (a university paper in fact) that is easy to understand, to the point, and free to download from here: http://arxiv.org/abs/cs.DS/0112022 (See PostScript or PDF link at bottom) Anyway, based on this very good document, I've written a C# function to compare two strings, and give a percentage on how close the strings are to one another as such: // Found http://arxiv.org/abs/cs.DS/0112022 // July 6, 2004 // From: qi xiao yang // Date (v1): Fri, 21 Dec 2001 05:58:12 GMT (250kb) // Date (revised v2): Tue, 25 Dec 2001 21:29:22 GMT (294kb) // Faster Algorithm of String Comparison // Authors: Qi Xiao Yang, Sung Sam Yuan, Lu Chun, Li Zhao, Sun Peng private double StringCompareValue(string str1, string str2) { string strX, strY; // smaller and bigger of the strings, respectively double val; // return value int window, wPos; // window width and position double SSNC = 0; // value used to calculate return in the end // get smaller & bigger strings sorted out // also, perform lower case conversion if(str1.Length < str2.Length) { strX = str1.ToLower(); strY = str2.ToLower(); } else { strX = str2.ToLower(); strY = str1.ToLower(); } // initialize window = strX.Length; wPos = 0; // while the window exists and the smallest string exists while(window > 0 && strX.Length > 0) { // while the window doesn't overlap the end of the string while((wPos + window) <= strX.Length) { // get string to compare to string comparer = strX.Substring(wPos, window); // start comparison point at zero int cPos = 0; // loop through second string to get all possible comparisons while(cPos + window <= strY.Length) { // if comparisons match if(comparer == strY.Substring(cPos, window)) { // update SSNC Value SSNC += Math.Pow((2 * window), 2); // remove "used characters" strY = strY.Remove(cPos, window); strX = strX.Remove(wPos, window); // force window position to stay same place (moved forward again at end of loop) wPos--;; // continue search with next window position break; } // move right on lon

Hi folks, I'm looking to find some code, or guidance for producing my own code, which would give me a score (say a percent value) on how similar two strings are. Any ideas are appreciated. Note: I've found, online, something about a Trigram algorithm for the purpose, but couldn't understand it fully. It seemed to be looking more at the meaning of two sentences (i.e. if they contain synonyms), which isn't quite what I'm looking for. As an example, if my comparison sentence is: "I'm looking for a needle in a haystack" then I'd like "I'm looking for needles in a haystack" to give me a better score than "I'm looking for needles in haystacks", but the scores should be pretty close. Thanks R

Hello, "+ Is the button that is being disabled on the active form or another form?" A: The button is found on the same panel in the MDIParent as the button that is being clicked when it is disabled. "+ Also you say the code jumps out of the onclick handler, did you mean focus only but code executes fine." A: The code after the ( Button.Enable = false; ) line is not executed - I found out through MessageBox.Show() that it is the last line executed, after which the focus shifts to another form and the OnMDIChildActivate() code is executed. And, I might add, there is plenty of code after that last line... I'm thinking that to find the 'current' mdi form window may take lots of work for every button event and such. I'm thinking more along the lines of having to create a custom button out of images as it doesn't seem to have the "jumping focus" for anything but the buttons. More suggestions are welcome - and no matter what I do for a solution, I would still like to find an explanation... Remus

Hello, I cannot figure out where this problem comes from, so I'm looking for suggestions. In my windows app I have multiple MDIs open as well as a panel on the MDI Parent. This panel contains buttons that get disabled ( btn01.Enable = false; ) programmatically when another button is clicked. I can reproduce this every time: 1. The buttons and labels on this "parent" panel are enabled and populated respectively from the OnMDIChildActivate() event. 2. When a button is clicked, another button is disabled. Due to that last event the active MDI child changes to the first one opened rather than to continue with the code in the function being processed (the onClick event handler). Note: There is no event handler for the "disable button" event. Note: The OnMDIChildActivate() event takes a DataSet from the MDI Child which it uses to populate the panel. Any suggestions? Thanks, Remus
