  • Make a Perl-style regex interpreter behave like a basic or extended regex interpreter

    - by Barry Brown
    I am writing a tool to help students learn regular expressions. I will probably be writing it in Java. The idea is this: the student types in a regular expression and the tool shows which parts of a text will get matched by the regex. Simple enough. But I want to support several different regex "flavors" such as: Basic regular expressions (think: grep) Extended regular expressions (think: egrep) A subset of Perl regular expressions, including the character classes \w, \s, etc. Sed-style regular expressions Java has the java.util.Regex class, but it supports only Perl-style regular expressions, which is a superset of the basic and extended REs. What I think I need is a way to take any given regular expression and escape the meta-characters that aren't part of a given flavor. Then I could give it to the Regex object and it would behave as if it was written for the selected RE interpreter. For example, given the following regex: ^\w+[0-9]{5}-(\d{4})?$ As a basic regular expression, it would be interpreted as: ^\\w\+[0-9]\{5\}-\(\\d\{4\}\)\?$ As an extended regular expression, it would be: ^\\w+[0-9]{5}-(\\d{4})?$ And as a Perl-style regex, it would be the same as the original expression. Is there a "regular expression for regular expressions" than I could run through a regex search-and-replace to quote the non-meta characters? What else could I do? Are there alternative Java classes I could use?

  • View all ntext column text in SQL Server Management Studio for SQL CE database

    - by Dave
    I often want to do a "quick check" of the value of a large text column in SQL Server Management Studio (SSMS). The maximum number of characters that SSMS will let you view, in grid results mode, is 65535. (It is even less in text results mode.) Sometimes I need to see something beyond that range. Using SQL Server 2005 databases, I often used the trick of converting it to XML, because SSMS lets you view much larger amounts of text that way: SELECT CONVERT(xml, MyCol) FROM MyTable WHERE ... But now I am using SQL CE, and there is no Xml data type. There is still a "Maximum Characters Retreived XML" value under Options; I suppose this is useful when connecting to other data sources. I know I can just get the full value by running a little console app or something, but is there a way within SSMS to see the entire ntext column value? [Edit] OK, this didn't get much attention the first time around (18 views?!). It's not a huge concern, but maybe I'm just obsessed with it. There has to be some good way around this, doesn't there? So a modest bounty is active. What I am willing to accept as answers, in order from best-to-worst: A solution that works just as easy as the XML trick in SQL CE. That is, a single function (convert, cast, etc.) that does the job. A not-too-invasive way to hack SSMS to get it to display more text in the results. An equivalent SQL query (perhaps something that creatively uses SUBSTRING and generates multiple ad-hoc columns??) to see the results. The solution should work with nvarchar and ntext columns of any length in SQL CE from SSMS. Any ideas?

  • How to use Excel VBA to extract Memo field from Access Database?

    - by the.jxc
    I have an Excel spreadsheet. I am connecting to an Access database via ODBC. Something along then lines of: Set dbEng = CreateObject("DAO.DBEngine.40") Set oWspc = dbEng.CreateWorkspace("ODBCWspc", "", "", dbUseODBC) Set oConn = oWspc.OpenConnection("Connection", , True, "ODBC;DSN=CLIENTDB;") Then I use a query and fetch a result set to get some table data. Set oQuery = oConn.CreateQueryDef("tmpQuery") oQuery.Sql = "SELECT idField, memoField FROM myTable" Set oRs = oQuery.OpenRecordset The problem now arises. My field is a dbMemo because the maximum content length is up to a few hundred chars. It's not that long, and in fact the value I'm reading is only a dozen characters. But Excel just doesn't seem able to handle the Memo field content at all. My code... ActiveCell = oRs.Fields("memoField") ...gives error Run-time error '3146': ODBC--call failed. Any suggestions? Can Excel VBA actually get at memo field data? Or is it just completely impossible. I get exactly the same error from GetChunk as well. ActiveCell = oRs.Fields("memoField").GetChunk(0, 2) ...also gives error Run-time error '3146': ODBC--call failed. Converting to a text field makes everything work fine. However some data is truncated to 255 characters of course, which means that isn't a workable solution.

  • Using NSXMLParser with CDATA

    - by Robb
    I'm parsing an RSS feed with NSXMLParser and it's working fine for the title and other strings but one of the elements is an image thats like <!CDATA <a href="http:image..etc> How do I add that as my cell image in my table view? Would I define that as an image type? This is what i'm using to do my parsing: - (void)parser:(NSXMLParser *)parser didStartElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName attributes:(NSDictionary *)attributeDict{ //NSLog(@"found this element: %@", elementName); currentElement = [elementName copy]; if ([elementName isEqualToString:@"item"]) { // clear out our story item caches... item = [[NSMutableDictionary alloc] init]; currentTitle = [[NSMutableString alloc] init]; currentDate = [ [NSMutableString alloc] init]; currentSummary = [[NSMutableString alloc] init]; currentLink = [[NSMutableString alloc] init]; } } - (void)parser:(NSXMLParser *)parser didEndElement:(NSString *)elementName namespaceURI:(NSString *)namespaceURI qualifiedName:(NSString *)qName{ //NSLog(@"ended element: %@", elementName); if ([elementName isEqualToString:@"item"]) { // save values to an item, then store that item into the array... [item setObject:currentTitle forKey:@"title"]; [item setObject:currentLink forKey:@"link"]; [item setObject:currentSummary forKey:@"description"]; [item setObject:currentDate forKey:@"date"]; [stories addObject:[item copy]]; NSLog(@"adding story: %@", currentTitle); } } - (void)parser:(NSXMLParser *)parser foundCharacters:(NSString *)string{ //NSLog(@"found characters: %@", string); // save the characters for the current item... if ([currentElement isEqualToString:@"title"]) { [currentTitle appendString:string]; } else if ([currentElement isEqualToString:@"link"]) { [currentLink appendString:string]; } else if ([currentElement isEqualToString:@"description"]) { [currentSummary appendString:string]; } else if ([currentElement isEqualToString:@"pubDate"]) { [currentDate appendString:string]; } }

  • Problem retrieving Strings from varbinary columns using HIbernate and MySQL

    - by user303396
    Hello, Here's my scenario. I save a bunch of Strings containing asian characters in MySQL using Hibernate. These strings are written in varbinary columns. Everything works fine during the saving operation. The DB contains the correct values (sequence of bytes). If I query (again using Hibernate) for the Strings that I saved I get the correct results. But when Hibernate fills the entity to which the Strings belong with the values from the DB I get different values then the ones I used in the query that retrieved them. Instead of receiving the correct values I receive a bunch of FFFD replacement characters. For example: if I store "??" in the DB and then I query for it, the resulting String will be \uFFFD\uFFFD\uFFFD\uFFFD\uFFFD\uFFFD. the DB connection has the following parameters set useUnicode=true&characterEncoding=UTF-8, I've tried using the true UTF-8 configurations for Hibernate but that didn't solve the problem What am I missing? Any suggestions? Thanks

  • Filemaker to SQL Server via SSIS

    - by TexasT
    I'm using SSIS and trying to import data from Filelmaker into SQL Server. In the Solution Explorer, I right click on "SSIS Packages" and select SQL Server Import and Export Wizard". During the process, I use my DSN as the source, SQL Server as the destination, use a valid query to pull data from Filemaker, and set the mappings. Each time I try to run the package, I receive the following message: The "output column "LastNameFirst" (12)" has a length that is not valide. The length must be between 0 and 4000. I do not understand this error exactly, but in the documentation for ODBC: http://www.filemaker.com/downloads/pdf/fm9%5Fodbc%5Fjdbc%5Fguide%5Fen.pdf (page 47) it states: "The maximum column length of text is 1 million characters, unless you specify a smaller Maximum number of characters for the text field in FileMaker. FileMaker returns empty strings as NULL." I'm thinking that the data type is too large when trying to convert it to varchar. But even after using a query of SUBSTR(LastNameFirst, 1, 2000), I get the same error. Any suggestions?

  • Android addTextChangedListener onTextChanged not fired when Backspace is pressed?

    - by tsil
    I use addTextChangeListener to filter a list items. When the user enters a character on the editText, items are filtered based on user input. For example, if the user enters "stackoverflow", all items that contains "stackoverflow" are displayed. It works fine except that once the user press backspace to delete character(s), items are no longer filtered until he deletes all characters. For example, my items are: "stackoverflow 1", "stackoverflow 2", "stackoverflow 3", "stackoverflow 4". If user input is "stackoverflow", all items are displayed. If user input is "stackoverflow 1", only "stackoverflow 1" is displayed. Then user deletes the last 2 characters (1 and the space). User input is now "stackoverflow" but "stackoverflow 1" is still displayed and the other items are not displayed. This is my custom filter: private class ServiceFilter extends Filter { @Override protected FilterResults performFiltering(CharSequence constraint) { FilterResults results = new FilterResults(); if (constraint == null || constraint.length() == 0) { // No filter implemented we return all the list results.values = origServiceList; results.count = origServiceList.size(); } else { List<ServiceModel> nServiceList = new ArrayList<ServiceModel>(); for (ServiceModel s : serviceList) { if (s.getName().toLowerCase().contains(constraint.toString().toLowerCase())) { nServiceList.add(s); } } results.values = nServiceList; results.count = nServiceList.size(); } return results; } @Override protected void publishResults(CharSequence constraint, FilterResults results) { if (results.count == 0) { notifyDataSetInvalidated(); } else { serviceList = (List<ServiceModel>) results.values; notifyDataSetChanged(); } } } And how I handle text change event: inputSearch.addTextChangedListener(new TextWatcher() { @Override public void afterTextChanged(Editable arg0) { // TODO Auto-generated method stub } @Override public void beforeTextChanged(CharSequence arg0, int arg1, int arg2, int arg3) { // TODO Auto-generated method stub } @Override public void onTextChanged(CharSequence cs, int arg1, int arg2, int arg3) { if (cs.length() >= 1) { mAdapter.getFilter().filter(cs); } else { mAdapter = new ServiceAdapter(MyActivity.this, R.layout.ussd_list_item, serviceList); listView.setAdapter(mAdapter); } } });

  • NSURLErrorBadURL error

    - by Victor jiang
    My iphone app called Google Local Search(non javascript version) to behave some search business. Below is my code to form a url: NSString *url = [NSString stringWithFormat:@"http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=%@", keyword]; NSMutableURLRequest *request = [[[NSMutableURLRequest alloc] init] autorelease]; [request setURL:[NSURL URLWithString:url]]; [request setHTTPMethod:@"GET"]; //get response NSHTTPURLResponse* urlResponse = nil; NSError *error = [[[NSError alloc] init] autorelease]; NSData *responseData = [NSURLConnection sendSynchronousRequest:request returningResponse:&urlResponse error:&error]; NSString *result = [[NSString alloc] initWithData:responseData encoding:NSUTF8StringEncoding]; When the keyword refers to english characters, it works fine, but when refers to chinese characters(encoded in UTF8, such as '???' whose UTF8 code is 'e5a4a9 e5ae89 e997a8'), it will report NSURLErrorBadURL error(-1000, Returned when a URL is sufficiently malformed that a URL request cannot be initiated). Why? Then I carry out further investigation, I use Safari and type in the url below: http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=??? It also works, and the output I got from Macsniffer is: /ajax/services/search/local?v=1.0&q=%E5%A4%A9%E5%AE%89%E9%97%A8 So I write a testing url directly in my app NSString *url = [NSString stringWithFormat:@"http://ajax.googleapis.com/ajax/services/search/local?v=1.0&q=%E5%A4%A9%E5%AE%89%E9%97%A8"]; And what I got from the Macsniffer is some other thing: /ajax/services/search/local?v=1.0&q=1.687891E-28750X1.417C0001416CP-102640X1.4CC2D04648FBP-9999-1.989891E+0050X1.20DC00184CC67P-953E8E99A8 It seems my keyword "%E5%A4%A9%E5%AE%89%E9%97%A8" was translated into something else. So how can I form a valid url? I do need help!

  • C# Check if character exists in encoding

    - by Alvin Wong
    I am writing a program that a part renders a bitmap font in CP437. In a function that renders the text with I want to be able to check whether a char is available in CP437 before the encoding conversion, like: public static void DrawCharacter(this Graphics g, char c) { if (char_exist_in_encoding(Encoding.GetEncoding(437), c) { byte[] src = Encoding.Unicode.GetBytes(c.ToString()); byte[] dest = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(437), src); DrawCharacter(g, dest[0]); // Call the void(this Graphics, byte) overload } } Without the check, any characters outside CP437 will result in a '?' (63, 0x3F). I want to hide any invalid characters completely. Is there an implementation of char_exist_in_encoding other than the following stupid approach? public static bool char_exist_in_encoding(Encoding e, char c) { if (c == '?') return true; byte[] src = Encoding.Unicode.GetBytes(c.ToString()); byte[] dest = Encoding.Convert(Encoding.Unicode, Encoding.GetEncoding(437), src); if (dest[0] == 0x3F) return false; return true; } Perhaps not very relevant, but the bitmap is created like this: Bitmap b = new Bitmap(256 * 8, 16); Graphics g = Graphics.FromImage(b); g.TextRenderingHint = System.Drawing.Text.TextRenderingHint.SingleBitPerPixelGridFit; Font f = new Font("Whatever 8x16 bitmap font", 16, GraphicsUnit.Pixel); for (byte i = 0; i < 255; i++) { byte[] arr = Encoding.Convert(Encoding.GetEncoding(437), Encoding.Unicode, new byte[] { i }); char c = Encoding.Unicode.GetChars(arr)[0]; g.DrawString(c.ToString(), f, Brushes.Black, i * 8 - 3, 0); // Don't know why it needs a 3px offset } b.Save(@"D:\chars.png");

  • ASP.Net menu databinding encoding problem

    - by WtFudgE
    Hi, I have a menu where I bind data through: XmlDataSource xmlData = new XmlDataSource(); xmlData.DataFile = String.Format(@"{0}{1}\Navigation.xml", getXmlPath(), getLanguage()); xmlData.XPath = @"/Items/Item"; TopNavigation.DataSource = xmlData; TopNavigation.DataBind(); The problem is when my xml has special characters, since I use a lot of french words. As an alternative I tried using a stream instead and using encoding to get the special characters, with the following code: StreamReader strm = new StreamReader(String.Format(@"{0}{1}\Navigation.xml", getXmlPath(), getLanguage()), Encoding.GetEncoding(1254)); XmlDocument xDoc = new XmlDocument(); xDoc.Load(strm); XmlDataSource xmlData = new XmlDataSource(); xmlData.ID = "TopNav"; xmlData.Data = xDoc.InnerXml; xmlData.XPath = @"/Items/Item"; TopNavigation.Items.Clear(); TopNavigation.DataSource = xmlData; TopNavigation.DataBind(); The problem I'm having now is that my data doesn't refresh when I change the path where the stream gets read. When I skip through the code it does, but not on my page. So the thing is either, how do I get the data te be refreshed? Or (which is actually preferred) how do I get the encoding right in the first piece of code? Help is highly apreciated!

  • Setting WPF RichTextBox width and height according to the size of a monospace font

    - by oxeb
    I am trying to fit a WPF RichTextBox to exactly accommodate a grid of characters in a particular monospace font. I am currently using FormattedText to determine the width and height of my RichTextBox, but the measurements it is providing me with are too small--specifically two characters in width too small. Is there a better way to perform this task? This does not seem to be an appropriate way to determine the size of my control. RichTextBox rtb; rtb = new RichTextBox(); FontFamily fontFamily = new FontFamily("Consolas"); double fontSize = 16; char standardizationCharacter = 'X'; String standardizationLine = ""; for(long loop = 0; loop < columns; loop ++) { standardizationLine += standardizationCharacter; } standardizationLine += Environment.NewLine; String standardizationString = ""; for(long loop = 0; loop < rows; loop ++) { standardizationString += standardizationLine; } Typeface typeface = new Typeface(fontFamily, FontStyles.Normal, FontWeights.Normal, FontStretches.Normal); FormattedText formattedText = new FormattedText(standardizationString, CultureInfo.CurrentCulture, FlowDirection.LeftToRight, typeface, fontSize, Brushes.Black); rtb.Width = formattedText.Width; rtb.Height = formattedText.Height;

  • JAVA Regular Expression Errors

    - by Berkay
    I'm working on a simply password strength checker and i can not success applying regular expressions. In different resources different kinds of regular expressions are defined. i also find javascript regular expressions but had some problems to adapt. First, these are the regular expressions i need for JAVA: at least one lower case letter at least one upper case letter at least one number at least three numbers at least one special character at least two special characters both letters and numbers both upper and lower case letters, numbers, and special characters My goal is not being a regular expression expert i just want to use the parts i need.If you direct me good tutorials which discusses above for java, will be appreciated. Second, in this link some of them are mentioned but i'm getting problems to apply them. here does not catch the lower case letter (my pass: A5677a) if (passwd.matches("(?=.*[a-z])")) // [verified] at least one lower case letter {Score = Score+5;} Also here i'm getting error : illegal escape character. if (passwd.matches("(?=.*\d)")) // [verified] at least one number Finally, are these expressions all different in different kind of programming or script languages?

  • ASP.NET MVC, Url Routing: Maximum Path (URL) Length

    - by Martin Aatmaa
    The Scenario I have an application where we took the good old query string URL structure: ?x=1&y=2&z=3&a=4&b=5&c=6 and changed it into a path structure: /x/1/y/2/z/3/a/4/b/5/c/6 We're using ASP.NET MVC and (naturally) ASP.NET routing. The Problem The problem is that our parameters are dynamic, and there is (theoretically) no limit to the amount of parameters that we need to accommodate for. This is all fine until we got hit by the following train: HTTP Error 400.0 - Bad Request ASP.NET detected invalid characters in the URL. IIS would throw this error when our URL got past a certain length. The Nitty Gritty Here's what we found out: This is not an IIS problem IIS does have a max path length limit, but the above error is not this. Learn dot iis dot net How to Use Request Filtering Section "Filter Based on Request Limits" If the path was too long for IIS, it would throw a 404.14, not a 400.0. Besides, the IIS max path (and query) length are configurable: <requestLimits maxAllowedContentLength="30000000" maxUrl="260" maxQueryString="25" /> This is an ASP.NET Problem After some poking around: IIS Forums Thread: ASP.NET 2.0 maximum URL length? http://forums.iis.net/t/1105360.aspx it turns out that this is an ASP.NET (well, .NET really) problem. The shit of the matter is that, as far as I can tell, ASP.NET cannot handle paths longer than 260 characters. The nail in the coffin in that this is confirmed by Phil the Haack himself: Stack Overflow ASP.NET url MAX_PATH limit Question ID 265251 The Question So what's the question? The question is, how big of a limitation is this? For my app, it's a deal killer. For most apps, it's probably a non-issue. What about disclosure? No where where ASP.NET Routing is mentioned have I ever heard a peep about this limitation. The fact that ASP.NET MVC uses ASP.NET routing makes the impact of this even bigger. What do you think?

  • finding "line-breaks" in textarea that is word-wrapping ARABIC text

    - by Irfan jamal
    I have a string of text that I display in a textarea (right-to-left orientation). The user can resize the textarea dynamically (I use jquery for this) and the text will wrap as necessary. When the user hits submit, I will take that text and create an image using PHP, BUT before submitting I would like to know where the "line-breaks" or rather "word-wraps" occur. Everywhere I have looked so far only shows me how to process line-breaks on the php side. I want to make it clear that there ARE NO LINE-BREAKS. What I have is one LONG string that will be word-wrapped in different ways based on the width of the textarea set by the user. I can't use "columns" or any other standard width representation because I have a very complex arabic font that is actually composed of glyphs (characters) of numerous different widths. If anyone knows of a way of accessing where the word wraps occur (either in a textarea or a div if need-be), I'd really like to know. My only other solution is to actually store (in my DB) the width of every single character (somewhat tedious since there are over 200 characters in 600 different fonts, for a total of...some huge number). My hopes aren't high, but I thought I would ask. Thanks i. jamal

  • Find does not work in Expect Send command

  • Getting started with character and text processing (encoding, regular expressions)

    - by TK
    I'd like to learn foundations of encodings, characters and text. Understanding these is important for dealing with a large set of text whether that are log files or text source for building algorithms for collective intelligence. My current knowledge is pretty basic: something like "As long as I use UTF-8, I'm okay." I don't say I need to learn about advanced topics right away. But I need to know: Bit and bytes level knowledge of encodings. Characters and alphabets not used in English. Multi-byte encodings. (I understand some Chinese and Japanese. And parsing them is important.) Regular expressions. Algorithm for text processing. Parsing natural languages. I also need an understanding of mathematics and corpus linguistics. The current and future web (semantic, intelligent, real-time web) needs processing, parsing and analyzing large text. I'm looking for some resources (maybe books?) that get me started with some of the bullets. (I find many helpful discussion on regular expressions here on Stack Overflow. So, you don't need to suggest resources on that topic.)

  • Charset and POST request

    - by jriff
    Hi All! I have a Rails 2.3.5 application that is working fine with UTF-8 and international characters. Now I have made some integration to a payment gateway where I POST some data, wait a while and get a POST back. The problem is that when I get that post back the international characters are broken. Instead of "sørensen" I get: "sørensen". If I do an iconv -fISO-8859-1 -tUTF8 it gets correctly converted to the former (I do that from a OS X command prompt). I have examined the POST request with logger.info(request.headers.inspect) in my controller and I can see that no charset parameter is given. As far as I can see the POST from the gateway must be UTF8 since one character (ø) gets translated to two (ø). So why does Rails think that the POST is ISO-8859-1? I know that one solution is to simply convert the params-hash with Iconv in the controller but I would like to know what is happening. Thanks in advance. Regards, Jacob

  • How do I pass a cookie to a Sinatra app using curl?

    - by Brandon Toone
    I'm using the code from the example titled "A Slightly Bigger Example" from this tutorial http://rubylearning.com/blog/2009/09/30/cookie-based-sessions-in-sinatra/ to figure out how to send a cookie to a Sinatra application but I can't figure out how to set the values correctly When I set the name to be "brandon" in the application it creates a cookie with a value of BAh7BiIJdXNlciIMYnJhbmRvbg%3D%3D%0A which is a url encoding (http://ostermiller.org/calc/encode.html) of the value BAh7BiIJdXNlciIMYnJhbmRvbg== Using that value I can send a cookie to the app correctly curl -b "rack.session=BAh7BiIJdXNlciIMYnJhbmRvbg==" localhost:9393 I'm pretty sure that value is a base64 encoding of the ruby hash for the session since the docs (http://rack.rubyforge.org/doc/classes/Rack/Session/Cookie.html) say The session is a Ruby Hash stored as base64 encoded marshalled data set to :key (default: rack.session). I thought that meant all I had to do was base64 encode {"user"=>"brandon"} and use it in the curl command. Unfortunately that creates a different value than BAh7BiIJdXNlciIMYnJhbmRvbg==. Next I tried taking the base64 encoded value and decoding it at various base64 decoders online but that results in strange characters (a box symbol and others) so I don't know how to recreate the value to even encode it. So my question is do you know what characters/format I need to get the proper base64 encoding and/or do you know of another way to pass a value using curl such that it will register as a proper cookie for a Sinatra app?

  • Workaround for GNU Make 3.80 eval bug

    - by bengineerd
    I'm trying to create a generic build template for my Makefiles, kind of like they discuss in the eval documentation. I've run into a known bug with GNU Make 3.80. When $(eval) evaluates a line that is over 193 characters, Make crashes with a "Virtual Memory Exhausted" error. The code I have that causes the issue looks like this. SRC_DIR = ./src/ PROG_NAME = test define PROGRAM_template $(1)_SRC_DIR = $$(SRC_DIR)$(1)/ $(1)_SRC_FILES = $$(wildcard $$($(1)_SRC_DIR)*.c) $(1)_OBJ_FILES = $$($(1)_SRC_FILES):.c=.o) $$($(1)_OBJ_FILES) : $$($(1)_SRC_FILES) # This is the problem line endef $(eval $(call PROGRAM_template,$(PROG_NAME))) When I run this Makefile, I get gmake: *** virtual memory exhausted. Stop. The expected output is that all .c files in ./src/test/ get compiled into .o files (via an implicit rule). The problem is that $$($(1)_SRC_FILES) and $$($(1)_OBJ_FILES) are together over 193 characters long (if there are enough source files). I have tried running the make file on a directory where there is only 2 .c files, and it works fine. It's only when there are many .c files in the SRC directory that I get the error. I know that GNU Make 3.81 fixes this bug. Unfortunately I do not have the authority or ability to install the newer version on the system I'm working on. I'm stuck with 3.80. So, is there some workaround? Maybe split $$($(1)_SRC_FILES) up and declare each dependency individually within the eval?

  • Full Text Search MSSQL2008 show wrong display_item for Thai Language

    - by ensecoz
    I am working on MSSQL2008. My task is to investigate the issue that why FTS cannot find the right result for Thai. First, I am having the table which enable the FTS on the column 'ItemName' which is nvarchar. The Catalog is created with the Thai Language. Note that, Thai language is one of the language that doesn't separate the word by space so '????' '???' '????' are written like this in the sentence '???????????' In the table, there are many rows that include the word (????) for examples row#1 (ItemName: '???????????') On the webpage, I try to search for '????' but SQLServer cannot find it. So I try to investigate it by trying the following query in SQLServer select * from sys.dm_fts_parser(N'"???????????"', 1054, 0, 0) To see how the words are broken. The first one is the text to be break. The second parameter is specify that using Thai (WorkBreaker, so on). and here is the result: row#1 (display_item: '????', source_item: '???????????') row#2 (display_item: '????', source_item: '???????????') row#3 (display_item: '??', source_item: '???????????') Notice that the first and second row display the worng display_item '?' in the '????' isn't even Thai characters. '?' in '????' is not Thai charater either. So the question is where is those alien characters come from? I guess this i why I cannot search for '????' because the word breaker is mis-borken and keeping the wrong character in the indexes. Please help!

  • C# Textbox validation should only accept integer values, but allows letters as well

    - by sonny5
    if (textBox1.Text != "") // this forces user to enter something { // next line is supposed to allow only 0-9 to be entered but should block all... // ...characters and should block a backspace and a decimal point from being entered.... // ...but it is also allowing characters to be typed in textBox1 if(!IsNumberInRange(KeyCode,48,57) && KeyCode!=8 && KeyCode!=46) // 46 is a "." { e.Handled=true; } else { e.Handled=false; } if (KeyCode == 13) // enter key { TBI1 = System.Convert.ToInt32(var1); // converts to an int Console.WriteLine("TBI1 (var1 INT)= {0}", var1); Console.WriteLine("TBI1= {0}", TBI1); } if (KeyCode == 46) { MessageBox.Show("Only digits...no dots please!"); e.Handled = !char.IsDigit(e.KeyChar) && !char.IsControl(e.KeyChar); } } else { Console.WriteLine("Cannot be empty!"); } // If I remove the outer if statement and skip checking for an empty string, then // it prevents letters from being entered in the textbox. I need to do both, prevent an // empty textbox AND prevent letters from being entered. // thanks, Sonny5

  • c#: how to read parts of a file? (DICOM)

    - by Xaisoft
    I would like to read a DICOM file in C#. I don't want to do anything fancy, I just for now would like to know how to read in the elements, but first I would actually like to know how to read the header to see if is a valid DICOM file. It consists of Binary Data Elements. The first 128 bytes are unused (set to zero), followed by the string 'DICM'. This is followed by header information, which is organized into groups. A sample DICOM header First 128 bytes: unused DICOM format. Followed by the characters 'D','I','C','M' Followed by extra header information such as: 0002,0000, File Meta Elements Groups Len: 132 0002,0001, File Meta Info Version: 256 0002,0010, Transfer Syntax UID: 1.2.840.10008.1.2.1. 0008,0000, Identifying Group Length: 152 0008,0060, Modality: MR 0008,0070, Manufacturer: MRIcro In the above example, the header is organized into groups. The group 0002 hex is the file meta information group which contains 3 elements: one defines the group length, one stores the file version and the their stores the transfer syntax. Questions How to I read the header file and verify if it is a DICOM file by checking for the 'D','I','C','M' characters after the 128 byte preamble? How do I continue to parse the file reading the other parts of the data?

  • Missing chars in JpGraph

    - by Álvaro G. Vicario
    I have a web site that runs on Windows and uses cp1252 (aka Win-1252) so it can display Spanish characters. The app generates some plots with JpGraph 2.3. These plots use the Tahoma Open Type font family to display text labels. Strings are provided in ANSI (i.e., cp1252) and font files support cp1252 (actually, the *.ttf files were copied from the system's font folder). It's been working fine in several setups from PHP/5.2.6 to PHP/5.3.0. Problems started when I ran the app under PHP/5.3.1: all non-ASCII are replaced by the hollow rectangle that represents missing or unknown chars. JpGraph's documentation is not very precise about how it expects international chars. Apparently, text is handled internally by the imagettftext() function, which expects UTF-8. However, encoding everything as UTF-8 breaks the app in all the systems. Where ANSI used to work fine, I get wrong characters (Ê instead of Ú). Where I got missing chars, now I get a PHP error: Warning: imagettftext(): any2eucjp(): something happen Do you have any clue about what changed in GD2 from PHP/5.3.0 to 5.3.1 that could be affecting the rendering on non-ASCII chars? How am I expected to feed JpGraph with strings in the Win-1252 charset?
