    - by Tushar Tarkas
    I am writing a client code for a server which Delete API. The API specification requires data to be sent. I am using HttpComponents v3.1 library for writing client code. Using the HtpDelete class I could not find a way to add request data to it. Is there a way to do so ? Below is the code snippet. HttpDelete deleteReq = new HttpDelete(uriBuilder.toString()); List<NameValuePair> postParams = new ArrayList<NameValuePair>(); postParams.add(new BasicNameValuePair(RestConstants.POST_DATA_PARAM_NAME, postData.toString())); try { UrlEncodedFormEntity entity = new UrlEncodedFormEntity(postParams); entity.setContentEncoding(HTTP.UTF_8); //deleteReq.setEntity(entity); // There is no method setEntity() deleteReq.setHeader(RestConstants.CONTENT_TYPE_HEADER, RestConstants.CONTENT_TYPE_HEADER_VAL); } catch (UnsupportedEncodingException e) { logger.error("UnsupportedEncodingException: " + e); } Thanks in advance.

  • MVC2 IModelBinder and parsing a string to an object - How do I do it?

    - by burnt_hand
    I have an object called Time public class Time{ public int Hour {get;set;} public int Minute {get;set;} public static Time Parse(string timeString){ //reads the ToString()'s previous output and returns a Time object } override protected string ToString(){ //puts out something like 14:50 (as in 2:50PM) } } So what I want is for the automatic model binding on the Edit or Create action to set this Time instance up from a string (i.e. feed the Parse method with the string and return the result). The reason I am doing this is that I will have a DropDownList with selectable times. The value of each option will be the parser readable string. Can anyone provide an example BindModel method from the IModelBinder interface?

  • StreamWriter stops writing when file is opened from web link

    Following on from my previous question... The following code creates log files on a web server: private void LogMessage(Message msg) { using (StreamWriter sw = File.AppendText(_logDirectory + DateTime.Now.ToString("yyyyMMddHH") + ".txt")) { sw.WriteLine(msg.ToString()); } } The log files are linked to from an admin page on the web site: foreach (FileInfo file in logDir.GetFiles()) { Response.Write("<a href='http:// .... /Logs/" + file.Name + "'>" + file.Name + "</a>"); } I'm getting the problem that after someone looks at one of the log files from the link, that log file stops being written to.

  • Problem while configuring the file Delimeter("\t") in app.config(C#3.0)

    In my app.config file I made the setting like the following <add key = "Delimeter" value ="\t"/> Now while accessing the above from the program by using the below code string delimeter = ConfigurationManager.AppSettings["FileDelimeter"].ToString(); StreamWriter streamWriter = null; streamWriter = new StreamWriter(fs); streamWriter.BaseStream.Seek(0, SeekOrigin.End); Enumerable .Range(0, outData.Length) .ToList().ForEach(i => streamWriter.Write(outData[i].ToString() + delimiter)); streamWriter.WriteLine(); streamWriter.Flush(); I am getting the output as 18804\t20100326\t5.59975381254617\t 18804\t20100326\t1.82599797249479\t But if I directly use "\t" in the delimeter variable I am getting the correct output 18804 20100326 5.59975381254617 18804 20100326 1.82599797249479 I found that while I am specifying the "\t" in the config file, and while reading it into the delimeter variable, it is becoming "\\t" which is the problem.

I have three different types of permissions like Admin, Leads, Programmers. These all three will have access to the gridview. Except admin if anyone tries to edit the gridview on clicking the edit option, I need to give an alert like This row has important validation and make sure you make proper changes. When I edit, the action with happen on table called Application. The table has a column called Comments. Also the alert should happen only when they try to edit rows where the Comments column have these values in them.

  • How can I ignore an http request without clearing the browser?

    - by Timid Developer
    To prevent duplicate requests (i.e. pressing F5 right after clicking a command button), I've setup my page base class to ignore the request if it's detected as a duplicate. When I say 'ignore' I mean Response.End() Now I thought I've seen this work before, where there's an issue, I just Response.End() and the users page just does nothing. I don't know the exact circumstance in which this worked, but I'm unable to repeat it now. Now when I call Response.End(), I just get an empty browser. More specifically, I get this html. <!DOCTYPE HTML PUBLIC "-//W3C//DTD HTML 4.0 Transitional//EN"> <HTML><HEAD> <META http-equiv=Content-Type content="text/html; charset=utf-8"></HEAD> <BODY></BODY></HTML> I setup the following test app to confirm the problem is not elsewhere in my app. Here it is: Add the following to an aspx form <asp:Label ID="lbl" Text="0" runat="server" /><br /> <asp:Button ID="btnAdd1" Text="Add 1" runat="server" /><br /> <asp:Button ID="btnAdd2" Text="Add 2" runat="server" /><br /> <asp:Button ID="btnAdd3" Text="Add 3" runat="server" /><br /> And here's the code behind file using System; namespace TestDupRequestCancellation { public partial class _Default : System.Web.UI.Page { protected void Page_Init(object sender, EventArgs e) { btnAdd1.Click += btnAdd1_Click; btnAdd2.Click += btnAdd2_Click; btnAdd3.Click += btnAdd3_Click; } protected void Page_Load(object sender, EventArgs e) { if (!IsPostBack) CurrentValue = 0; else if (Int32.Parse(lbl.Text) != CurrentValue) Response.End(); } protected void Page_PreRender(object sender, EventArgs e) { lbl.Text = CurrentValue.ToString(); } protected int CurrentValue { get { return Int32.Parse(Session["CurrentValue"].ToString()); } set { Session["CurrentValue"] = value.ToString(); } } void btnAdd3_Click(object sender, EventArgs e) { CurrentValue += 3; } void btnAdd2_Click(object sender, EventArgs e) { CurrentValue += 2; } void btnAdd1_Click(object sender, EventArgs e) { CurrentValue += 1; } } } When you load the page, clicking any button does what is expected, but if you press F5 at any time after pressing one of the buttons, it will detect it as a duplicate request and call Response.End() which promptly ends the task. Which leaves the user with an empty browser. Is there anyway to leave the user with the page as it was, so they can just click a button? Also; please note that this code is the simplest code I could come up with to demonstrate my problem. It's not meant to demonstrate how to check for dup requests.

  • C2360 compiler error on TFS build, but not on desktop

    - by pdmaguire
    A c++ code snippet similar to the code below caused our TFS build to fail with a C2360 compiler error. switch (i) { case 0 : for each (int n in a) System::Console::WriteLine(n.ToString()); break; case 1 : System::Console::WriteLine("n is not in scope here"); break; } This is fixed by using {} brackets within the body of case 0, as below: switch (i) { case 0 : { for each (int n in a) System::Console::WriteLine(n.ToString()); } break; case 1 : System::Console::WriteLine("n is not in scope here"); break; } The developer had successfully compiled the code on their desktop before committing the changes. A cursory look at versions of things like compilers, Visual Studio etc on the server and desktop suggest they are the same. The source code is the same, obviously. What is the difference between a desktop build and TFS build that would smother a compiler error like this?

  • Using Apache Velocity with StringBuilders/CharSequences

    - by mindas
    We are using Apache Velocity for dynamic templates. At the moment Velocity has following methods for evaluation/replacing: public static boolean evaluate(Context context, Writer writer, String logTag, Reader reader) public static boolean evaluate(Context context, Writer out, String logTag, String instring) We use these methods by providing StringWriter to write evaluation results. Our incoming data is coming in StringBuilder format so we use StringBuilder.toString and feed it as instring. The problem is that our templates are fairly large (can be megabytes, tens of Ms on rare cases), replacements occur very frequently and each replacement operation triples the amount of required memory (incoming data + StringBuilder.toString() which creates a new copy + outgoing data). I was wondering if there is a way to improve this. E.g. if I could find a way to provide a Reader and Writer on top of same StringBuilder instance that only uses extra memory for in/out differences, would that be a good approach? Has anybody done anything similar and could share any source for such a class? Or maybe there any better solutions to given problem?

  • Creating/Handling events for controls when added during runtime.

    - by AllStar11
    I am using a Repeater which contains a placeholder. The placeholder is bound to my database and each ItemTemplate contains 1-6 radiobuttons depending on what the database returns. What I need to do is somehow keep track of which one of the radiobuttons is checked for each question so I can write the user's answers to the database when they complete the test, any ideas?? <asp:Repeater ID="Repeater1" OnItemDataBound="R1_ItemDataBound" runat="server"> <ItemTemplate> <asp:PlaceHolder ID="phAnswers" runat="server"> </asp:PlaceHolder> </ItemTemplate> </asp:Repeater> Sub R1_ItemDataBound(ByVal Sender As Object, ByVal e As RepeaterItemEventArgs) Dim tempPH As PlaceHolder tempPH = e.Item.FindControl("phAnswers") For x As Integer = 0 To (t_MC.Count - 1) newRadio = New RadioButton newRadio.ID = "Answer" + x.ToString newRadio.GroupName = "Answer" + tempQuestion.ID.ToString newRadio.Text = t_MC(x).Value newRadio.Width = 800 tempPH.Controls.Add(newRadio)

  • ASP.NET Repeater and DataBinder.Eval

    - by Fernando
    I've got a <asp:Repeater> in my webpage, which is bound to a programatically created dataset. The purpose of this repeater is to create an index from A-Z, which, when clicked, refreshes the information on the page. The repeater has a link button like so: <asp:LinkButton ID="indexLetter" Text='<%#DataBinder.Eval(Container.DataItem,"letter")%>' runat="server" CssClass='<%#DataBinder.Eval(Container.DataItem, "cssclass")%>' Enabled='<%#DataBinder.Eval(Container.DataItem,"enabled")%>'></asp:LinkButton> The dataset is created the following way: protected DataSet getIndex(String index) { DataSet ds = new DataSet(); ds.Tables.Add("index"); ds.Tables["index"].Columns.Add("letter"); ds.Tables["index"].Columns.Add("cssclass"); ds.Tables["index"].Columns.Add("enabled"); char alphaStart = Char.Parse("A"); char alphaEnd = Char.Parse("Z"); for (char i = alphaStart; i <= alphaEnd; i++) { String cssclass="", enabled="true"; if (index == i.ToString()) { cssclass = "selected"; enabled = "false"; } ds.Tables["index"].Rows.Add(new Object[3] {i.ToString(),cssclass,enabled }); } return ds; } However, when I run the page, a "Specified cast is not valid exception" is thrown in Text='<%#DataBinder.Eval(Container.DataItem,"letter")'. I have no idea why, I have tried manually casting to String with (String), I've tried a ToString() method, I've tried everything. Also, if in the debugger I add a watch for DataBinder.Eval(Container.DataItem,"letter"), the value it returns is "A", which according to me, should be fine for the Text Property. EDIT: Here is the exception: System.InvalidCastException was unhandled by user code Message="Specified cast is not valid." Source="App_Web_cmu9mtyc" StackTrace: at ASP.savecondition_aspx._DataBinding_control7(Object sender, EventArgs e) in e:\Documents and Settings\Fernando\My Documents\Visual Studio 2008\Projects\mediTrack\mediTrack\saveCondition.aspx:line 45 at System.Web.UI.Control.OnDataBinding(EventArgs e) at System.Web.UI.Control.DataBind(Boolean raiseOnDataBinding) at System.Web.UI.Control.DataBind() at System.Web.UI.Control.DataBindChildren() InnerException: Any advice will be greatly appreciated, thank you EDIT 2: Fixed! The problem was not in the Text or CSS tags, but in the Enabled tag, I had to cast it to a Boolean value. The problem was that the exception was signaled at the Text tag, I don't know why

    I have a server running that accepts connections made through client sockets, I need to read the input from this client socket, now suppose the client opened a connection to my server without sending anything through the server's socket outputstream, in this case, while my server tried to read the input through the client socket's inputstream, an exception will be thrown, but before the exception is thrown i would like a timeout say of 5 sec, how can I do this? currently here's how my code looks like on the server side: try { InputStreamReader clientInputStream = new InputStreamReader(clientSocket.getInputStream()); int c; StringBuffer requestBuffer = new StringBuffer(); while ((c = clientInputStream.read()) != -1) { requestBuffer.append((char) c); if (requestBuffer.toString().endsWith(("\r\n\r\n"))) break; } request = new Request(requestBuffer.toString(), clientSocket); } catch (Exception e) // catch any possible exception in order to keep the thread running { try { if (clientSocket != null) clientSocket.close(); } catch (IOException ex) { ex.printStackTrace(); } System.err.println(e); //e.printStackTrace(); }

  • Gotchas INSERTing into SQLite on Android?

    - by paul.meier
    Hi friends, I'm trying to set up a simple SQLite database in Android, handling the schema via a subclass of SQLiteOpenHelper. However, when I query my tables, the columns I think I've inserted are never present. Namely, in SQLiteOpenHelper's onCreate(SQLiteDatabase db) method, I use db.execSQL() to run CREATE TABLE commands, then have tried both db.execSQL and db.insert() to run INSERT commands on the tables I've just created. This appears to run fine, but when I try to query them I always get 0 rows returned (for debugging, the queries I'm running are simple SELECT * FROM table and checking the Cursor's getCount()). Anybody run into anything like this before? These commands seem to run on command-line sqlite3. Are they're gotchas that I'm missing (e.g. INSERTS must/must not be semicolon terminated, or some issue involving multiple tables)? I've attached some of the code below. Thanks for your time, and let me know if I can clarify further. @Override public void onCreate(SQLiteDatabase db) { db.execSQL("CREATE TABLE "+ LEVEL_TABLE +" (" + " "+ _ID +" INTEGER PRIMARY KEY AUTOINCREMENT," + " level TEXT NOT NULL,"+ " rows INTEGER NOT NULL,"+ " cols INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ DYNAMICS_TABLE +" (" + " level_id INTEGER NOT NULL," + " row INTEGER NOT NULL,"+ " col INTEGER NOT NULL,"+ " type INTEGER NOT NULL);"); db.execSQL("CREATE TABLE "+ SCORE_TABLE +" (" + " level_id INTEGER NOT NULL," + " score INTEGER NOT NULL,"+ " date_achieved DATE NOT NULL,"+ " name TEXT NOT NULL);"); this.enterFirstLevel(db); } And a sample of the insert code I'm currently using, which gets called in enterFirstLevel() (some values hard-coded just to get it running...): private void insertDynamic(SQLiteDatabase db, int row, int col, int type) { ContentValues values = new ContentValues(); values.put("level_id", "1"); values.put("row", Integer.toString(row)); values.put("col", Integer.toString(col)); values.put("type", Integer.toString(type)); db.insertOrThrow(DYNAMICS_TABLE, "col", values); } Finally, query code looks like this: private Cursor fetchLevelDynamics(int id) { SQLiteDatabase db = this.leveldata.getReadableDatabase(); try { String fetchQuery = "SELECT * FROM " + DYNAMICS_TABLE; String[] queryArgs = new String[0]; Cursor cursor = db.rawQuery(fetchQuery, queryArgs); Activity activity = (Activity) this.context; activity.startManagingCursor(cursor); return cursor; } finally { db.close(); } }

  • .NET AES returns wrong Test Vectors

    - by ralu
    I need to implement some crypto protocol on C# and want to say that this is my first project in C#. After spending some time to get used on C# I found out that I am unable to get compliant AES vectors. using System; using System.Collections.Generic; using System.Linq; using System.Text; using System.Security.Cryptography; using System.IO; namespace ConsoleApplication1 { class Program { public static void Main() { try { //test vectors from "ecb_vk.txt" byte[] key = { 0x80, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; byte[] data = { 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00, 0x00 }; byte[] encTest = { 0x0e, 0xdd, 0x33, 0xd3, 0xc6, 0x21, 0xe5, 0x46, 0x45, 0x5b, 0xd8, 0xba, 0x14, 0x18, 0xbe, 0xc8 }; AesManaged aesAlg = new AesManaged(); aesAlg.BlockSize = 128; aesAlg.Key = key; aesAlg.Mode = CipherMode.ECB; ICryptoTransform encryptor = aesAlg.CreateEncryptor(); MemoryStream msEncrypt = new MemoryStream(); CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write); StreamWriter swEncrypt = new StreamWriter(csEncrypt); swEncrypt.Write(data); swEncrypt.Close(); csEncrypt.Close(); msEncrypt.Close(); aesAlg.Clear(); byte[] encr; encr = msEncrypt.ToArray(); string datastr = BitConverter.ToString(data); string encrstr = BitConverter.ToString(encr); string encTestStr = BitConverter.ToString(encTest); Console.WriteLine("data: {0}", datastr); Console.WriteLine("encr: {0}", encrstr); Console.WriteLine("should: {0}", encTestStr); Console.ReadKey(); } catch (Exception e) { Console.WriteLine("Error: {0}", e.Message); } } } } Output is wrong: data: 00-00-00-00-00-00-00-00-00-00-00-00-00-00-00-00 encr: A0-3C-C2-22-A4-32-F7-C9-BA-36-AE-73-66-BD-BB-A3 should: 0E-DD-33-D3-C6-21-E5-46-45-5B-D8-BA-14-18-BE-C8 I am sure that there is a correct AES implementation in .NET, so I need some advice from a .NET wizard to help with this.

  • How to format a string as a telephone number in C#

    - by Brian G
    I have a string "1112224444' it is a telephone number. I want to format as 111-222-4444 before I store it in a file. It is on a datarecord and I would prefer to be able to do this without assigning a new variable. I was thinking: String.Format("{0:###-###-####}", i["MyPhone"].ToString() ); but that does not seem to do the trick. ** UPDATE ** Ok. I went with this solution Convert.ToInt64(i["Customer Phone"]).ToString("###-###-#### ####") Now its gets messed up when the extension is less than 4 digits. It will fill in the numbers from the right. so 1112224444 333 becomes 11-221-244 3334 Any ideas?
