  • How to parse date from string ?

    - by Harikrishna
    I want to parse the date from the string where date formate can be any of different format. Now to match date we can use DateTime.TryParseExact and we can define format as we needed and date will be matched for any different format. string[] formats = {"MMM dd yyyy"}; DateTime dateValue; string dateString = "May 26 2008"; if (DateTime.TryParseExact(dateString, formats, new CultureInfo("en-US"), DateTimeStyles.None, out dateValue)) MessageBox.Show(dateValue.ToString()); This matches with date.But this is not working for parse the date from the string that is it does not matched with the date which is in some string. Like if the date is "May 26 2008" then we can define format "MMM dd yyyy" and date will be matched. But if date is in some string like "Abc May 26 2008" then date will not be matched.So for that can we use regular expression here ? If yes how ?

  • ObjectContext ConnectionString Sqlite

    - by codegarten
    I need to connect to a database in Sqlite so i downloaded and installed System.Data.SQLite and with the designer dragged all my tables. The designer created a .cs file with public class Entities : ObjectContext and 3 constructors: 1st public Entities() : base("name=Entities", "Entities") this one load the connection string from App.config and works fine. App.config <connectionStrings> <add name="Entities" connectionString="metadata=res://*/Db.TracModel.csdl|res://*/Db.TracModel.ssdl|res://*/Db.TracModel.msl;provider=System.Data.SQLite;provider connection string=&quot;data source=C:\Users\Filipe\Desktop\trac.db&quot;" providerName="System.Data.EntityClient" /> </connectionStrings> 2nd public Entities(string connectionString) : base(connectionString, "Entities") 3rd public Entities(EntityConnection connection) : base(connection, "Entities") Here is the problem, i already tried n configuration, already used EntityConnectionStringBuilder to make the connection string with no luck. Can you please point me in the right direction!? EDIT(1) How can i construct a valid connection string?!

  • Standard Place for an Empty String Array in the JDK

    - by Simon B
    Hi is there a standard place for accessing empty array constants in the JDK 1.5. When I want to do a conversion from a String Collection (e.g. ArrayList)to a String Array I find myself using my own which is defined in my own Constants class: public static final String[] EMPTY_STRING_ARRAY = new String[0]; And then in my client code something like: String[] retVal = myStringList.toArray(Constants.EMPTY_STRING_ARRAY); return retVal; I was wondering if this is the "idiomatic" of doing it or if I'm missing something I get the impression from the brief search I did that this kind of thing is prevalent in many people's code. Any ideas, answers, comment (aside from that I shouldn't really use String Arrays) greatly appreciated, Cheers Simon

  • Unable to retrieve the complete description string of the event log record

    - by Santosh Pillai
    Hi All, I have an MFC application that reads and displays event log records using the ::ReadEventLog() API. The problem is with reading the "Description" message string of the event log record. The MFC application is unable to read the complete "Description" message string and displays only some part of it. However the Windows System Event Log Viewer reads and displays the complete "Description" message string correctly. I have ensured that my MFC application reads the entire "Description" message string by retrieving all the strings as provided by the "NumStrings" and "StringOffset" member variables of the EVENTLOGRECORD structure and merging all of them. Also as mentioned in MSDN my application loads the Source Name specific message library file (whose path is specified in the registry at HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\EventLog\Application[SourceName]) that further contains additional message string information and merges it with the earlier read strings. I am still unable to get the entire "Description" message string. Please provide any help towards resolving the issue. Regards, Santosh.

  • SQL SERVER – Grouping by Multiple Columns to Single Column as A String

    - by pinaldave
    One of the most common questions I receive in email is how to group multiple column data in comma separate values in a single row grouping by another column. I have previously blogged about it in following two blog posts. However, both aren’t addressing the following exact problem. Comma Separated Values (CSV) from Table Column Comma Separated Values (CSV) from Table Column – Part 2 The question comes in many different formats but in following image I am demonstrating the same question in simple words. This is the most popular question on my Facebook page as well. (Example) Here is the sample script to build the sample dataset. CREATE TABLE TestTable (ID INT, Col VARCHAR(4)) GO INSERT INTO TestTable (ID, Col) SELECT 1, 'A' UNION ALL SELECT 1, 'B' UNION ALL SELECT 1, 'C' UNION ALL SELECT 2, 'A' UNION ALL SELECT 2, 'B' UNION ALL SELECT 2, 'C' UNION ALL SELECT 2, 'D' UNION ALL SELECT 2, 'E' GO SELECT * FROM TestTable GO Here is the solution which will build an answer to the above question. -- Get CSV values SELECT t.ID, STUFF( (SELECT ',' + s.Col FROM TestTable s WHERE s.ID = t.ID FOR XML PATH('')),1,1,'') AS CSV FROM TestTable AS t GROUP BY t.ID GO I hope this is an easy solution. I am going to point to this blog post in the future for all the similar questions. Final Clean Up Act -- Clean up DROP TABLE TestTable GO Here is the question back to you - Is there any better way to write above script? Please leave a comment and I will write a separate blog post with due credit.

  • String patterns that can be used to filter and group files

    - by Louis Rhys
    One of our application filters files in certain directory, extract some data from it and export a document from the extracted data. The algorithm for extracting the data depends on the file, and so far we use regex to select the algorithm to be used, for example .*\.txt will be processed by algorithm A, foo[0-5]\.xml will be processed by algo B, etc. However now we need some files to be processed together. For example, in one case we need two files, foo.*\.xml and bar.*\.xml. Part of the information to be extracted exist in the foo file, and the other part in the bar file. Moreover, we need to make sure the wild card is compatible. For example, if there are 6 files foo1.xml foo23.xml bar1.xml bar9.xml bar23.xml foo4.xml I would expect foo1 and bar1 to be identified as a group, and foo23 and bar23 as another group. bar9 and foo4 has no pair, so they will not be treated. Now, since the filter is configured by user, we need to have a pattern that can express the above requirement. I don't think you can express meaning like above in standard regex. (foo|bar).*\.xml will match all 6 file above and we can't identify which file is paired for a particular file. Is there any standard pattern that can express it? Or any idea how to modify regex to support this, that can be implemented easily?

  • Python UTF-16 encoding hex representation

    - by Romeno
    I have a string in Python 2.7.2 say u"\u0638". When I write it to file: f = open("J:\\111.txt", "w+") f.write(u"\u0638".encode('utf-16')) f.close() In hex it looks like: FF FE 38 06 When i print such a string to stdout i will see: '\xff\xfe8\x06'. The querstion: Where is \x38 in the string output to stdout? In other words why the string output to stdout is not '\xff\xfe\x38\x06'? If I write the string to file twice: f = open("J:\\111.txt", "w+") f.write(u"\u0638".encode('utf-16')) f.write(u"\u0638".encode('utf-16')) f.close() The hex representation in file contains byte order mark (BOM) \xff\xfe twice: FF FE 38 06 FF FE 38 06 I wonder what is the techique to avoid writting BOM in UTF-16 encoded strings?

  • Writing String.trim() in C

    - by Phoenix
    Hi guys, I was writing the String trim method in c and this is the code I came up with. I think it does the job of eliminating leading and trailing whitespaces however, I wish the code could be cleaner. Can you suggest improvements. void trim(char *String) { int i=0;j=0; char c,lastc; while(String[i]) { c=String[i]; if(c!=' ') { String[j]=c; j++; } else if(lastc!= ' ') { String[j]=c; j++; } lastc = c; i++; } Does this code look clean ??

  • C# String Operator Overloading

    G'Day Mates - What is the right way (excluding the argument of whether it is advisable) to overload the string operators <, , <= and = ? I've tried it five ways to Sunday and I get various errors - my best shot was declaring a partial class and overloading from there, but it won't work for some reason. namespace System { public partial class String { public static Boolean operator <(String a, String b) { return a.CompareTo(b) < 0; } public static Boolean operator >(String a, String b) { return a.CompareTo(b) > 0; } } }

  • ASP.net Literal or Page altering HTML string, causing formatting issues

    - by Jon
    We have a service that generates a report (using word templates and a 3rd party library), and then returns a string in HTML. While this HTML isn't great - its formatted correctly in this string. We want this HTML to show up on a page - format intact. What we currently have done is set an ASP.net Literal's text element to this string. While this works, I have noticed that it has reformatted the HTML string slightly. For the most part, it looks like it generated a bunch of new CSS classes, and a new style element in the HTML. This HTML does not exist in the string thats being returned. I could filter all of this back out, but wonder if there is a better way. I assume that the Page itself is altering something. What is the best way to display this raw HTML back to the user? I can't directly use a Response.Write(string), because this page does have a few other controls on it.

  • Convert CString to string (VC6)

    - by Yan Cheng CHEOK
    I want to convert CString to string. (Yup. I know what am I doing. I know the returned string will be incorrect, if CString value range is outside ANSI, but That's Is OK!) The following code will work under VC2008. std::string Utils::CString2String(const CString& cString) { // Convert a TCHAR string to a LPCSTR CT2CA pszConvertedAnsiString (cString); // construct a std::string using the LPCSTR input std::string strStd (pszConvertedAnsiString); return strStd; } But VC6 doesn't have CT2CA macro. How I can make the code to work as well in both VC6 and VC2008?

  • NSFormatter problem: not getting called for the empty string

    - by Enchilada
    I have created a custom formatter for my (read-only) table column. It looks like this: - (NSString *)stringForObjectValue:(id)anObject { NSAssert([anObject isKindOfClass:[NSString class]] && anObject != nil, @"invalid object"); if ([anObject isEqualToString:@""]) return @"EMPTY"; else return [anObject stringByAppendingString:@"++"]; } Very simple. The corresponding objects are just strings, so it's an string-to-string formatter. All non-empty string objects are returned with @"++" appended to them. Empty string objects should be turned into the @"EMPTY" string. The @"++" gets appended to non-empty strings just fine. The problem is, @"EMPTY" never gets shown! My formatter is never called by Cocoa when the underlying object is the empty string. The corresponding row just keeps being empty, instead of showing my requested @"EMPTY". Any ideas?

    Hi I have a .net object that I want to use in Excel. I have an existing VBA script that i need to alter to call this the object from. I have then converted the object to a TLB.

  • Python: Elegant way to check if at least one regex in list matches a string

    - by houbysoft
    Hi. I have a list of regexes in python, and a string. Is there an elegant way to check if the at least one regex in the list matches the string? By elegant, I mean something better than simply looping through all of the regexes and checking them against the string and stopping if a match is found. Basically, I had this code: list = ['something','another','thing','hello'] string = 'hi' if string in list: pass # do something else: pass # do something else Now I would like to have some regular expressions in the list, rather than just strings, and I am wondering if there is an elegant solution to check for a match to replace if string in list:. Thanks in advance.

  • Convert byte array to understandable String

    - by Ender
    I have a program that handles byte arrays in Java, and now I would like to write this into a XML file. However, I am unsure as to how I can convert the following byte array into a sensible String to write to a file. Assuming that it was Unicode characters I attempted the following code: String temp = new String(encodedBytes, "UTF-8"); Only to have the debugger show that the encodedBytes contain "\ufffd\ufffd ^\ufffd\ufffd-m\ufffd\ufffd\/ufffd \ufffd\ufffdIA\ufffd\ufffd". The String should contain a hash in alphanumerical format. How would I turn the above String into a sensible String for output?
