  • Vim: open files of the matches on the lines given by Grep?

    - by HH
    I want to get automatically to the positions of the results in Vim after grepping, on command line. Is there such feature? Files to open in Vim on the lines given by grep: % grep --colour -n checkWordInFile * SearchToUser.java:170: public boolean checkWordInFile(String word, File file) { SearchToUser.java~:17: public boolean checkWordInFile(String word, File file) { SearchToUser.java~:41: if(checkWordInFile(word, f))

  • polymorphism, inheritance in c# - base class calling overridden method?

    - by Andrew Johns
    This code doesn't work, but hopefully you'll get what I'm trying to achieve here. I've got a Money class, which I've taken from http://www.noticeablydifferent.com/CodeSamples/Money.aspx, and extended it a little to include currency conversion. The implementation for the actual conversion rate could be different in each project, so I decided to move the actual method for retrieving a conversion rate (GetCurrencyConversionRate) into a derived class, but the ConvertTo method contains code that would work for any implementation assuming the derived class has overriden GetCurrencyConversionRate so it made sense to me to keep it in the parent class? So what I'm trying to do is get an instance of SubMoney, and be able to call the .ConvertTo() method, which would in turn use the overriden GetCurrencyConversionRate, and return a new instance of SubMoney. The problem is, I'm not really understanding some concepts of polymorphism and inheritance yet, so not quite sure what I'm trying to do is even possible in the way I think it is, as what is currently happening is that I end up with an Exception where it has used the base GetCurrencyConversionRate method instead of the derived one. Something tells me I need to move the ConvertTo method down to the derived class, but this seems like I'll be duplicating code in multiple implementations, so surely there's a better way? public class Money { public CurrencyConversionRate { get { return GetCurrencyConversionRate(_regionInfo.ISOCurrencySymbol); } } public static decimal GetCurrencyConversionRate(string isoCurrencySymbol) { throw new Exception("Must override this method if you wish to use it."); } public Money ConvertTo(string cultureName) { // convert to base USD first by dividing current amount by it's exchange rate. Money someMoney = this; decimal conversionRate = this.CurrencyConversionRate; decimal convertedUSDAmount = Money.Divide(someMoney, conversionRate).Amount; // now convert to new currency CultureInfo cultureInfo = new CultureInfo(cultureName); RegionInfo regionInfo = new RegionInfo(cultureInfo.LCID); conversionRate = GetCurrencyConversionRate(regionInfo.ISOCurrencySymbol); decimal convertedAmount = convertedUSDAmount * conversionRate; Money convertedMoney = new Money(convertedAmount, cultureName); return convertedMoney; } } public class SubMoney { public SubMoney(decimal amount, string cultureName) : base(amount, cultureName) {} public static new decimal GetCurrencyConversionRate(string isoCurrencySymbol) { // This would get the conversion rate from some web or database source decimal result = new Decimal(2); return result; } }

  • null from C# getting converted into 'NULL' in Sql Server

    - by Anand
    I am trying to insert NULL value in Sql Server if I have null value in corresponding C# String object like below : String Residence = xmlDoc.Descendants("Appointment").Single().Element("StateOfResidence") == null ? null : xmlDoc.Descendants("Appointment").Elements("StateOfResidence").Single().Value; I am using Entity framework for Database access. So if Residence is null, 'NULL' gets inserted into Database instead of NULL. How can insert NULL for null ?

  • C# Parsing html for general use?

    - by Wardy
    What is the best way to take a string of html and turn it in to something useful? Essentially if i take a url and go get the html from that url in .net i get a response but this would come in the form of either a file or stream or string. What if i want an actual document or something I can crawl like an xmldocument object? I have some thoughts and an already implemented solution on this but I am interested to see what the community thinks about this.

  • Delphi simple TCP server hangs. The form freezes but the server continues managing the clients.

    - by NeoNMD
    I'm using a form with an IdTCPServer on it managing strings from the client with a AThread.connection.readln/writeln system. The string handling works and that isn't the problem. The thing is, the form with the server on it hangs and will not load, but it still managed all the clients connected to it so it IS running but it just doesn't work as a form. I'll make a guess that its sitting on a readline or something... but I have NO idea how i can fix this at this moment in time. Please help. procedure TMonitorFrm.ServerExecute(AThread: TIdPeerThread); procedure post(PostMessage:string); begin try AThread.Connection.WriteLn(PostMessage); except showmessage('Cannot post'); end; end; var ActClient : PClient; sTemp, CommBlock, NewCommBlock, ReceiverName, sContent, sSQL, sCommand : String; iCount2, iCount : Integer; sldb : TSQLiteDatabase; sltb : TSQLiteTable; begin if not AThread.Terminated and AThread.Connection.Connected then begin CommBlock := AThread.Connection.ReadLn(); ActClient := PClient(AThread.Data); ActClient.LastAction := Now; sCommand := copy(CommBlock,0,pos(',',CommBlock)-1); {seperate command} sContent := copy(CommBlock,pos(',',CommBlock)+1,length(CommBlock)-(pos(',',CommBlock)+1)); {seperate data block} iCount:= 0 ; if sCommand = 'Announce' then //SPECIAL begin { Do stuff for this command...} end else if sCommand = 'CheckSect' then {Etcetera...} procedure TMonitorFrm.FormCreate(Sender: TObject); var sCompetitionID : string; sldb : TSQLiteDatabase; sltb : TSQLiteTable; begin Clients := TThreadList.Create; Server.Active := True; AreaPnlList := TComponentList.Create; SectionPnlList := TComponentList.Create; Repeat until InputQuery('Competition Select', 'Please type the ID of the competition', sCompetitionID); iCompetitionID:=StrToInt(sCompetitionID); OpenDatabase(slDb); sltb:=slDb.GetTable('SELECT * FROM SectionTable WHERE CompetitionID='+sCompetitionID); Frame31.CreateSections(sltb,Frame31); sltb.Free; CloseDatabase(slDb); { This section needs to check the SQLite databases for sections and list them in the display window and makes a drag n drop profile... } end;

  • When to use LinkedList<> over ArrayList<>?

    - by sdellysse
    I've always been one to simply use List<String> names = new ArrayList<String>(); I use the interface as the type name for portability, so that when I ask questions such as these I can rework my code. When should LinkedList should be used over ArrayList and vice-versa?

  • Mysterious constraints problem with SQL Server 2000

    - by Ramon
    Hi all I'm getting the following error from a VB NET web application written in VS 2003, on framework 1.1. The web app is running on Windows Server 2000, IIS 5, and is reading from a SQL server 2000 database running on the same machine. System.Data.ConstraintException: Failed to enable constraints. One or more rows contain values violating non-null, unique, or foreign-key constraints. at System.Data.DataSet.FailedEnableConstraints() at System.Data.DataSet.EnableConstraints() at System.Data.DataSet.set_EnforceConstraints(Boolean value) at System.Data.DataTable.EndLoadData() at System.Data.Common.DbDataAdapter.FillFromReader(Object data, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords, DataColumn parentChapterColumn, Object parentChapterValue) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, String srcTable, IDataReader dataReader, Int32 startRecord, Int32 maxRecords) at System.Data.Common.DbDataAdapter.FillFromCommand(Object data, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet, Int32 startRecord, Int32 maxRecords, String srcTable, IDbCommand command, CommandBehavior behavior) at System.Data.Common.DbDataAdapter.Fill(DataSet dataSet) The problem appears when the web app is under a high load. The system runs fine when volume is low, but when the number of requests becomes high, the system starts rejecting incoming requests with the above exception message. Once the problem appears, very few requests actually make it through and get processed normally, about 2 in every 30. The vast majority of requests fail, until a SQL Server restart or IIS reset is performed. The system then start processing requests normally, and after some time it starts throwing the same error. The error occurs when a data adapter runs the Fill() method against a SELECT statement, to populate a strongly-typed dataset. It appears that the dataset does not like the data it is given and throws this exception. This error occurs on various SELECT statements, acting on different tables. I have regenerated the dataset and checked the relevant constraints, as well as the table from which the data is read. Both the dataset definition and the data in the table are fine. Admittedly, the hardware running both the web app and SQL Server 2000 is seriously outdated, considering the numbers of incoming requests it currently receives. The amount of RAM consumed by SQL Server is dynamically allocated, and at peak times SQL Server can consume up to 2.8 GB out of a total of 3.5 GB on the server. At first I suspected some sort of index or database corruption, but after running DBCC CHECKDB, no errors were found in the database. So now I'm wondering whether this error is a result of the hardware limitations of the system. Is it possible for SQL Server to somehow mess up the data it's supposed to pass to the dataset, resulting in constraint violation due to, say, data type/length mismatch? I tried accessing the RowError messages of the data rows in the retrieved dataset tables but I kept getting empty strings. I know that HasErrors = true for the datatables in question. I have not set the EnableConstraints = false, and I don't want to do that. Thanks in advance. Ray

  • When I mark a property as transient, does the type matter?

    - by mystify
    For example, I make a fullName property and set it to transient. Does it matter what data type that property is, in this case? For example, does it matter if it's set to int or string? As far as I get it, a transient property is almost "ignored" by Core Data. I make my accessors for that and when someone accesses fullName, I simply construct a string and return that. Did I miss something?

  • How to clear all form fields from code-behind?

    - by Slauma
    HTML has an input button type to reset all fields in a form to their initial state in one step: <input type="reset" ... />. Is there a similar simple way to reset all form fields of an aspx page from code-behind? Or is it necessary to reset all controls one by one with TextBox1.Text=string.Empty, TextBox2.Text=string.Empty, etc. ? Thanks in advance!
