• Pinax TemplateSyntaxError

  - by Spikie

  hi, i ran into this errors while trying to modify pinax database model i am using eclipse pydev i have this error on the pydev Exception Type: TemplateSyntaxError at / Exception Value: Caught an exception while rendering: (1146, "Table 'test1.announcements_announcement' doesn't exist") please how do i correct this UPDATE: i asked this question and left unresolved some months back and you what ran into the bug again this week and typed the error message in google hit the page with the question and unanswered so i think i have to answer it and hope it help someone in the future have the same problem. some the problem is that the sqlite path is out of place so django or this case pinax can not find it so to resolve that change the absolute path to sqlite like it DATABASE_ENGINE = 'sqlite3' # 'postgresql_psycopg2', 'postgresql', 'mysql', 'sqlite3' or 'ado_mssql'. DATABASE_NAME = os.path.join(PROJECT_ROOT,'dev.db' ) # Or path to database file if using sqlite3. DATABASE_USER = '' # Not used with sqlite3. DATABASE_PASSWORD = '' # Not used with sqlite3. DATABASE_HOST = '' # Set to empty string for localhost. Not used with sqlite3. DATABASE_PORT = '' # Set to empty string for default. Not used with sqlite3. i hope that help

• .NET RegEx - First N chars of First M lines

  - by George

  Hello! I want 4 general RegEx expressions for the following 4 basic cases: Up to A chars starting after B chars from start of line on up to C lines starting after D lines from start of file Up to A chars starting after B chars from start of line on up to C lines occurring before D lines from end of file Up to A chars starting before B chars from end of line on up to C lines starting after D lines from start of file Up to A chars starting before B chars from end of line on up to C lines starting before D lines from end of file These would allow to select arbitrary text blocks anywhere in the file. So far I have managed to come up with cases that only work for lines and chars separately: (?<=(?m:^[^\r]{N}))[^\r]{1,M} = UP TO M chars OF EVERY LINE, AFTER FIRST N chars [^\r]{1,M}(?=(?m:.{N}\r$)) = UP TO M chars OF EVERY LINE, BEFORE LAST N chars The above 2 expressions are for chars, and they return MANY matches (one for each line). (?<=(\A([^\r]*\r\n){N}))(?m:\n*[^\r]*\r$){1,M} = UP TO M lines AFTER FIRST N lines (((?=\r?)\n[^\r]*\r)|((?=\r?)\n[^\r]+\r?)){1,M}(?=((\n[^\r]*\r)|(\n[^\r]+\r?)){N}\Z) = UP TO M lines BEFORE LAST N lines from end These 2 expressions are equivalents for the lines, but they always return just ONE match. The task is to combine these expressions to allow for scenarios 1-4. Anyone can help? Note that the case in the title of the question, is just a subclass of scenario #1, where both B = 0 and D = 0. EXAMPLE: SOURCE: line1 blah 1 line2 blah 2 line3 blah 3 line4 blah 4 line5 blah 5 line6 blah 6 DESIRED RESULT: Characters 3-6 of lines 3-5: A total of 3 matches: <match>ne3 </match> <match>ne4 </match> <match>ne5 </match>

• how to access control in templatefield gridview with custom id

  - by Mohsen.Tavoosi

  i have a customized gridview.my grid is able to sort for each column just by 1 click in the header without any setting and overloading methods such as sorting,etc by user(programmer).(i do this successfully and work fine) users(programmers) maybe add each column in grid.such as template field,hyperlinkfield,boundfield... . for sorting, i must access datafield of columns. i can access boundfield column by this code.i can access datafield and header text and ... sample: for (int j = 0; j < this.Columns.Count; j++) { BoundField bf; bf = this.Columns[j] as BoundField; if (bf != null) { string ht = bf.HeaderText; string df = bf.DataField; } } but i can access control in the templateField.such as ColumnBound. sample: <asp:Label ID="Label1" runat="server" Text='<%# Bind("Name") %>'></asp:Label> i want access "Name" (Bind ("Name") or Eval ("Name")) . how can i? there is a point: i dont now what is the ID (in this case "Label1") of control in templatefield. special thanks

• Why Sql not bringing back results unless I set varchar size?

  - by Tom

  I've got an SQL script that fetches results based on the colour passed to it, but unless I set the size of the variable defined as a varchar to (50) no results are returned. If I use: like ''+@Colour+'%' then it works but I don't really want to use it in case it brings back results I don't need or want. The column FieldValue has a type of Varchar(Max) (which can't be changed as this field can store different things). It is part of aspdotnetstorefront package so I can't really change the tables or field types. This doesn't work: declare @Col VarChar set @Col = 'blu' select * from dbo.MetaData as MD where MD.FieldValue = @Colour But this does work: declare @Col VarChar (50) set @Col = 'blu' select * from dbo.MetaData as MD where MD.FieldValue = @Colour The code is used in the following context, but should work either way <query name="Products" rowElementName="Variant"> <sql> <![CDATA[ select * from dbo.MetaData as MD where MD.Colour = @Colour ]]> </sql> <queryparam paramname="@ProductID" paramtype="runtime" requestparamname="pID" sqlDataType="int" defvalue="0" validationpattern="^\d{1,10}$" /> <queryparam paramname="@Colour" paramtype="runtime" requestparamname="pCol" sqlDataType="varchar" defvalue="" validationpattern=""/> </query> Any Ideas?

• Design suggestion for expression tree evaluation with time-series data

  - by Lirik

  I have a (C#) genetic program that uses financial time-series data and it's currently working but I want to re-design the architecture to be more robust. My main goals are: sequentially present the time-series data to the expression trees. allow expression trees to access previous data rows when needed. to optimize performance of the data access while evaluating the expression trees. keep a common interface so various types of data can be used. Here are the possible approaches I've thought about: I can evaluate the expression tree by passing in a data row into the root node and let each child node use the same data row. I can evaluate the expression tree by passing in the data row index and letting each node get the data row from a shared DataSet (currently I'm passing the row index and going to multiple synchronized arrays to get the data). Hybrid: an immutable data set is accessible by all of the expression trees and each expression tree is evaluated by passing in a data row. The benefit of the first approach is that the data row is being passed into the expression tree and there is no further query done on the data set (which should increase performance in a multithreaded environment). The drawback is that the expression tree does not have access to the rest of the data (in case some of the functions need to do calculations using previous data rows). The benefit of the second approach is that the expression trees can access any data up to the latest data row, but unless I specify what that row is, I'll have to iterate through the rows and figure out which one is the last one. The benefit of the hybrid is that it should generally perform better and still provide access to the earlier data. It supports two basic "views" of data: the latest row and the previous rows. Do you guys know of any design patterns or do you have any tips that can help me build this type of system? Should I use a DataSet to hold and present the data, or are there more efficient ways to present rows of data while maintaining a simple interface? FYI: All of my code is written in C#.

• Convert a Relative URL to an Absolute URL in Actionscript / Flex

  - by Bear

  I am working with Flex, and I need to take a relative URL source property and convert it to an absolute URL before loading it. The specific case I am working with involves tweaking SoundEffect's load method. I need to determine if a file will be loaded from the local file system or over the network from looking at the source property, and the easiest way I've found to do this is to generate the absolute URL. I'm having trouble generating the absolute URL for sound effect in particular. Here were my initial thoughts, which haven't worked. Look for the DisplayObject that the Sound Effect targets, and use its loaderInfo property. The target is null when the SoundEffect loads, so this doesn't work. Look at FlexGlobals.topLevelApplication, at the url or loaderInfo properties. Neither of these are set, however. Look at the FlexGlobals.topLevelApplication.systemManager.loaderInfo. This was also not set. The SoundEffect.as code basically boils down to var url:String = "mySound.mp3"; /*>> I'd like to convert the URL to absolute form here and tweak it as necessary <<*/ var req:URLRequest = new URLRequest(url); var loader:Loader = new Loader(); loader.load(req); Does anyone know how to do this? Any help clarifying the rules of how relative urls are resolved for URLRequests in ActionScript would also be much appreciated. edit I would also be perfectly satisfied with some way to tell whether the url will be loaded from the local file system or over the network. Looking at an absolute URL it would just be easy to look at the prefix, like file:// or http://.

• Invert a string: Recursion vs iteration in javascript

  - by steweb

  Hi all, one month ago I've been interviewed by some google PTO members. One of the questions was: Invert a string recursively in js and explain the running time by big O notation this was my solution: function invert(s){ return (s.length > 1) ? s.charAt(s.length-1)+invert(s.substring(0,s.length-1)) : s; } Pretty simple, I think. And, about the big-o notation, I quickly answered O(n) as the running time depends linearly on the input. - Silence - and then, he asked me, what are the differences in terms of running time if you implement it by iteration? I replied that sometimes the compiler "translate" the recursion into iteration (some programming language course memories) so there are no differences about iteration and recursion in this case. Btw since I had no feedback about this particular question, and the interviewer didn't answer "ok" or "nope", I'd like to know if you maybe agree with me or if you can explain me whether there could be differences about the 2 kind of implementations. Thanks a lot and Regards!

• How to use boost::bind with non-copyable params, for example boost::promise ?

  - by zhengxi

  Some C++ objects have no copy constructor, but have move constructor. For example, boost::promise. How can I bind those objects using their move constructors ? #include <boost/thread.hpp> void fullfil_1(boost::promise<int>& prom, int x) { prom.set_value(x); } boost::function<void()> get_functor() { // boost::promise is not copyable, but movable boost::promise<int> pi; // compilation error boost::function<void()> f_set_one = boost::bind(&fullfil_1, pi, 1); // compilation error as well boost::function<void()> f_set_one = boost::bind(&fullfil_1, std::move(pi), 1); // PS. I know, it is possible to bind a pointer to the object instead of // the object itself. But it is weird solution, in this case I will have // to take cake about lifetime of the object instead of delegating that to // boost::bind (by moving object into boost::function object) // // weird: pi will be destroyed on leaving the scope boost::function<void()> f_set_one = boost::bind(&fullfil_1, boost::ref(pi), 1); return f_set_one; }

• What harm can javascript do?

  - by The King

  I just happen to read the joel's blog here... So for example if you have a web page that says “What is your name?” with an edit box and then submitting that page takes you to another page that says, Hello, Elmer! (assuming the user’s name is Elmer), well, that’s a security vulnerability, because the user could type in all kinds of weird HTML and JavaScript instead of “Elmer” and their weird JavaScript could do narsty things, and now those narsty things appear to come from you, so for example they can read cookies that you put there and forward them on to Dr. Evil’s evil site. Since javascript runs on client end. All it can access or do is only on the client end. It can read informations stored in hidden fields and change them. It can read, write or manipulate cookies... But I feel, these informations are anyway available to him. (if he is smart enough to pass javascript in a textbox. So we are not empowering him with new information or providing him undue access to our server... Just curious to know whether I miss something. Can you list the things that a malicious user can do with this security hole. Edit : Thanks to all for enlightening . As kizzx2 pointed out in one of the comments... I was overlooking the fact that a JavaScript written by User A may get executed in the browser of User B under numerous circumstances, in which case it becomes a great risk.

• How does this code break the Law of Demeter?

  - by Dave Jarvis

  The following code breaks the Law of Demeter: public class Student extends Person { private Grades grades; public Student() { } /** Must never return null; throw an appropriately named exception, instead. */ private synchronized Grades getGrades() throws GradesException { if( this.grades == null ) { this.grades = createGrades(); } return this.grades; } /** Create a new instance of grades for this student. */ protected Grades createGrades() throws GradesException { // Reads the grades from the database, if needed. // return new Grades(); } /** Answers if this student was graded by a teacher with the given name. */ public boolean isTeacher( int year, String name ) throws GradesException, TeacherException { // The method only knows about Teacher instances. // return getTeacher( year ).nameEquals( name ); } private Grades getGradesForYear( int year ) throws GradesException { // The method only knows about Grades instances. // return getGrades().getForYear( year ); } private Teacher getTeacher( int year ) throws GradesException, TeacherException { // This method knows about Grades and Teacher instances. A mistake? // return getGradesForYear( year ).getTeacher(); } } public class Teacher extends Person { public Teacher() { } /** * This method will take into consideration first name, * last name, middle initial, case sensitivity, and * eventually it could answer true to wild cards and * regular expressions. */ public boolean nameEquals( String name ) { return getName().equalsIgnoreCase( name ); } /** Never returns null. */ private synchronized String getName() { if( this.name == null ) { this.name == ""; } return this.name; } } Questions How is the LoD broken? Where is the code breaking the LoD? How should the code be written to uphold the LoD?

• How do I locate a particular word in a text file using .NET

  - by cmrhema

  I am sending mails (in asp.net ,c#), having a template in text file (.txt) like below User Name :<User Name> Address : <Address>. I used to replace the words within the angle brackets in the text file using the below code StreamReader sr; sr = File.OpenText(HttpContext.Current.Server.MapPath(txt)); copy = sr.ReadToEnd(); sr.Close(); //close the reader copy = copy.Replace(word.ToUpper(),"#" + word.ToUpper()); //remove the word specified UC //save new copy into existing text file FileInfo newText = new FileInfo(HttpContext.Current.Server.MapPath(txt)); StreamWriter newCopy = newText.CreateText(); newCopy.WriteLine(copy); newCopy.Write(newCopy.NewLine); newCopy.Close(); Now I have a new problem, the user will be adding new words within an angle, say for eg, they will be adding <Salary>. In that case i have to read out and find the word <Salary>. In other words, I have to find all the words, that are located with the angle brackets (<). How do I do that?

• rails HABTM versus view (formtastic)

  - by VP

  I have two models: The model NetworkObject try to describe "hosts". I want to have a rule with source and destination, so i'm trying to use both objects from the same class since it dont makes sense to create two different classes. class NetworkObject < ActiveRecord::Base attr_accessible :ip, :netmask, :name has_many :statements has_many :rules, :through =>:statements end class Rule < ActiveRecord::Base attr_accessible :active, :destination_ids, :source_ids has_many :statements has_many :sources, :through=> :statements, :source=> :network_object has_many :destinations, :through => :statements, :source=> :network_object end To build the HABTM i did choose the Model JOIN. so in this case i created a model named Statement with: class Statement < ActiveRecord::Base attr_accessible :source_id, :rule_id, :destination_id belongs_to :network_object, :foreign_key => :source_id belongs_to :network_object, :foreign_key => :destination_id belongs_to :rule end The problem is: is right to add two belongs_to to the same class using different foreign_keys? I tried all combinations like: belongs_to :sources, :class_name => :network_object, :foreign_key => :source_id but no success.. anything that i am doing wrong?

• How is unautenticated site navigation handled in ASP.NET?

  - by Code Sherpa

  Hi. I am wondering how to do the following... I have a registration system. When the user successfully registers, he is then led down a series of data gathering pages (for his profile) and then, finally, ends on his profile's home page where he can start to use the site. All this happens without ever logging into the system so, he is unauthenticated and unconfirmed. My question is, how does this happen? How can I allow my user to be unauthenticated (and unconfirmed, but this I understand) and use all aspects of the Web site? The way I have things set up right now, my code should be doing this: case CreateProfileStatus.Success: //FormsAuthentication.SetAuthCookie(userName, false); Response.Redirect("NextPage.aspx", false); break; but, I am being redirected to the login page after registration which is not the result I want. This is what the relevant nodes in my web.config look like: <authentication mode="Forms"> <forms name=".AuthCookie" loginUrl="default.aspx" protection="All"/> </authentication> <authorization> <deny users="?"/> <allow roles="Administrators" /> </authorization> <anonymousIdentification enabled="true" cookieName=".ASPXANONYMOUS" cookieTimeout="100000" cookiePath="/" cookieRequireSSL="false" cookieSlidingExpiration="true" cookieProtection="Encryption" cookieless="UseCookies" domain="" /> When the user logs out after the registration and initial interaction with the site he will be required to log in upon return. At this point he must be authenticated but does not need to be confirmed for a period of time. Eventually, he will be reminded. So, how is this done? Thanks in advance.

• Why do IOExceptions occur in ReadableByteChannel.read()

  - by Steffen Heil

  Hi The specification of ReadableByteChannel.read() shows -1 as result value for end-of-stream. Moreover it specifies ClosedByInterruptExceptionas possible result if the thread is interrupted. Now I thought that would be all - and it is most of the time. However, now and then I get the following: java.io.IOException: Eine vorhandene Verbindung wurde vom Remotehost geschlossen at sun.nio.ch.SocketDispatcher.read0(Native Method) at sun.nio.ch.SocketDispatcher.read(SocketDispatcher.java:25) at sun.nio.ch.IOUtil.readIntoNativeBuffer(IOUtil.java:233) at sun.nio.ch.IOUtil.read(IOUtil.java:206) at sun.nio.ch.SocketChannelImpl.read(SocketChannelImpl.java:236) at ... I do not unterstand why I don't get -1 in this case. Also this is not a clean exception, as I cannot catch it without catching any possible IOException. So here are my questions: Why is this exception thrown in the first place? Is it safe to assume that ANY exception thrown by read are about the socket being closed? Is all this the same for write()? And by the way: If I call SocketChannel.close() do I have to call SocketChannel.socket().close() as well or is this implied by the earlier? Thanks, Steffen

• MFC Combo-Box Control is not showing the full list of items when I click the drop-down menu...

  - by shan23

  I'm coding an app in MSVS 2008, which has a ComboBox control which I initialize thru the code as below: static char* OptionString[4] = {"Opt1", "Opt2", "Opt3", "Opt4"}; BOOL CMyAppDlg::OnInitDialog() { CDialog::OnInitDialog(); // Set the icon for this dialog. The framework does this automatically // when the application's main window is not a dialog SetIcon(m_hIcon, TRUE); // Set big icon SetIcon(m_hIcon, FALSE); // Set small icon // TODO: Add extra initialization here m_Option.AddString(OptionString[0]); m_Option.AddString(OptionString[1]); m_Option.AddString(OptionString[2]); m_Option.AddString(OptionString[3]); m_Option.SetCurSel(0); return TRUE; // return TRUE unless you set the focus to a control } Now, when I build the app and click the down-arrow, the drop-down box shows the first option ONLY(since I've selected that thru my code). But, if i press down-arrow key on keyboard, it cycles thru the options in the order I've inserted, but never does it show more than 1 option in the box. So, In case an user wants to select option3, he has to cycle through options 1 and 2 !! Though once I select any option using the keyboard, the appropriate event handlers are fired, I'm miffed by this behaviour , as is understandable. I'm listing the properties of the combo-box control as well - only the properties that are true(rest are set to false): Type - Dropdown Vertical Scrollbar Visible Tabstop This has bugged me for weeks now. Can anyone pls enlighten me ?

• How does the last integer promotion rule ever get applied in C?

  - by SiegeX

  6.3.1.8p1: Otherwise, the integer promotions are performed on both operands. Then the following rules are applied to the promoted operands: If both operands have the same type, then no further conversion is needed. Otherwise, if both operands have signed integer types or both have unsigned integer types, the operand with the type of lesser integer conversion rank is converted to the type of the operand with greater rank. Otherwise, if the operand that has unsigned integer type has rank greater or equal to the rank of the type of the other operand, then the operand with signed integer type is converted to the type of the operand with unsigned integer type. Otherwise, if the type of the operand with signed integer type can represent all of the values of the type of the operand with unsigned integer type, then the operand with unsigned integer type is converted to the type of the operand with signed integer type. Otherwise, both operands are converted to the unsigned integer type corresponding to the type of the operand with signed integer type. For the bolded rule to be applied it would seem to imply you need to have have an unsigned interger type who's rank is less than the signed integer type and the signed integer type cannot hold all the values of the unsigned integer type. Is there a real world example of such a case or is this statement serving as a catch-all to cover all possible permutations?

• Prevent deferred creation of controls.

  - by Scott Chamberlain

  Here is a test framework to show what I am doing, just create a new project add a tabbed control, on tab 1 put a button on tab 2 put a check box (default names) and paste this code for its code public partial class Form1 : Form { private List<bool> boolList = new List<bool>(); BindingSource bs = new BindingSource(); public Form1() { InitializeComponent(); boolList.Add(false); bs.DataSource = boolList; checkBox1.DataBindings.Add("Checked", bs, ""); } bool updating = false; private void button1_Click(object sender, EventArgs e) { updating = true; boolList[0] = true; bs.ResetBindings(false); Application.DoEvents(); updating = false; } private void checkBox1_CheckedChanged(object sender, EventArgs e) { if (!updating) MessageBox.Show("CheckChanged fired outside of updating"); } } The issue is if you run the program and look at tab 2 then press the button on tab 1 the program works as expected, however if you press the button on tab 1 then look at tab 2 the event for the checkbox will not fire untill you look at tab 2. The reason for this is the controll on tab 2 is not in the "created" state, so its binding to change the checkbox from unchecked to checked does not happen until after the control has been "Created". checkbox1.CreateControl() does not do anything because according to MSDN CreateControl does not create a control handle if the control's Visible property is false. You can either call the CreateHandle method or access the Handle property to create the control's handle regardless of the control's visibility, but in this case, no window handles are created for the control's children. I tried getting the value of Handle(there is no CreateHandle for Button) but still the same result. Any suggestions other than have the program quickly flash all of my tabs that have data-bound check boxes when it first loads?

• Delphi How to wait for socket answer inside procedure?

  - by Astronavigator

  For some specific needs i need to create procedure that waits for socket request (or answer) in dll: TForm1 = class(TForm) ServerSocket1: TServerSocket; ...... procedure MyWaitProc; stdcall; begin Go := false; while not Go do begin // Wating... // Application.ProcessMessages; // Works with this line end; end; procedure TForm1.ServerSocket1ClientRead(Sender: TObject; Socket: TCustomWinSocket); begin MessageBoxA(0, PAnsiChar('Received: '+Socket.ReceiveText), '', MB_OK); Go := true; end; exports MyWaitProc; When I call Application.ProcessMessages everything works fine: application waits for request and then continues. But in my case calling Application.ProcessMessages causes to unlocking main form on host application (not dll's one). When I don't call Application.ProcessMessages application just hangs couse it cannot handle message... So, how to create such a procedure that's wating for socket answer ? Maybe there a way to wait for socket answer without using Application.ProcessMessages ? EDIT I also tried to use TIdTCPServer, for some reasons, the result is the same. TForm1 = class(TForm) IdTCPServer1: TIdTCPServer; ..... procedure MyWaitProc; stdcall; begin Go := false; while not Go do begin // Waiting ... // Application.ProcessMessages; end; end; procedure TForm1.IdTCPServer1Execute(AContext: TIdContext); var s: string; begin s := AContext.Connection.Socket.ReadString(1); AllText := AllText + s; Go := True; end;

• Which linear programming package should I use for high numbers of constraints and "warm starts"

  - by davidsd

  I have a "continuous" linear programming problem that involves maximizing a linear function over a curved convex space. In typical LP problems, the convex space is a polytope, but in this case the convex space is piecewise curved -- that is, it has faces, edges, and vertices, but the edges aren't straight and the faces aren't flat. Instead of being specified by a finite number of linear inequalities, I have a continuously infinite number. I'm currently dealing with this by approximating the surface by a polytope, which means discretizing the continuously infinite constraints into a very large finite number of constraints. I'm also in the situation where I'd like to know how the answer changes under small perturbations to the underlying problem. Thus, I'd like to be able to supply an initial condition to the solver based on a nearby solution. I believe this capability is called a "warm start." Can someone help me distinguish between the various LP packages out there? I'm not so concerned with user-friendliness as speed (for large numbers of constraints), high-precision arithmetic, and warm starts. Thanks!

• DQL delete from multiple tables (doctrine)

  - by singer

  Need to perform DQL delete from multple related tables. In SQL it is something like this: DELETE r1,r2 FROM ComRealty_objects r1, com_realty_objects_phones r2 WHERE r1.id IN (10,20) AND r2.id_object IN (10,20) I need to perform this statement using DQL, but I'm stuck on this :( <?php $dql = Doctrine_Query::create() ->delete('phones, comrealtyobjects') ->from('ComRealtyObjects comrealtyobjects') ->from('ComRealtyObjectsPhones phones') ->whereIn("comrealtyobjects.id", $ids) ->whereIn("phones.id_object", $ids); echo($dql->getSqlQuery()); ?> But DQL parser gives me this result: DELETE FROM `com_realty_objects_phones`, `ComRealty_objects` WHERE (`id` IN (?) AND `id_object` IN (?)) Searching google and stack overflow I found this(useful) topic: http://stackoverflow.com/questions/2247905/what-is-the-syntax-for-a-multi-table-delete-on-a-mysql-database-using-doctrine But this is not exactly my case - there was delete from single table. If there is a way to override dql parser behaviour? Or maybe some other way to delete records from multiple tables using doctrine. Note: If you are using doctrine behaviours(Doctrine_Record_Generator) you need first to initialize those tables using Doctrine_Core::initializeModels() to perform DQL operations on them.

• HtmlAgilityPack - Vs 2010 - c# ASP - File Not found

  - by Janosch Geigowskoskilu

  First, I've already searched the web & StackOverflow for hours, and i did find a lot about troubleshooting HtmlAgilityPack and tried most of these but nothing worked. The Situation: I'm developing a C# ASP .NET WebPart in SharePoint Foundation. Everything works fine, now I want to Parse a HTML Page to get all ImagePaths and save the Images on HD/Temp. To do that I was downloading HtmlAgilityPack, current version, add reference to Project, everything looks OK, IntelliSense works fine. The Exception: But when I want to run the section where HtmlAgilityPack should be used my Browser shows me a FileNotFoundException - The File or Assembly could not be found. What I tried: After first searches i tried to include v1.4.0 of HtmlAgilityPack cause I read that the current version in some case is not really stable. This works fine to until the point I want to use HtmlAgilityPack, the same Exception. I also tried moving the HtmlAgilityPack direct to the Solution directory, nothing changed. I tried to insert HtmlAgilityPack via using and I tried direct call e.g. HtmlAgilityPack.HtmlDocument. Conclusion : When I compile no error occurs, the reference is set correct. When I trace the HtmlAgilityPack.dll with ProcMon the Path is shown correct, but sometimes the Result is 'File Locked with only Readers' but I don't know enough about ProcMon to Know what this means or if this is critical. It couldn't have something to do with File Permissions because if I check the DLL the permissions are all given.

• asp.net multiligual website culture settings

  - by Hemant Kothiyal

  Hi, In asp.net multilingual website in english Uk and swedish, i have three rsources file 1. en-GB.resx 2. sv-SE.resx 3. Culture neutral file. I have create one base class and all pages is inherited from that class. There i write following lines to set UICULTURE and culture 1. Thread.CurrentThread.CurrentUICulture = CultureInfo.CurrentUICulture.Name; 2. Thread.CurrentThread.CurrentCulture = CultureInfo.CurrentCulture.Name; Question: Suppose my browser language is Swedish(sv-SE) then this code will run because it find CurrentUICulture and CurrentCulture values as sv-SE. Now if suppose browser language is Swedish(sv) only, in that case values will be set as CurrentUICulture = sv; and CurrentCulture = sv-SE Now the problem is that user can able to view all text in Culture neutral resource file that i kept as english while all decimal saperators, currency and other will be appear in swedish. It looks confusing to usr. What would be right approach. I am thinking following solution. Please correct me? 1. i can create extra resource file for sv also. 2. I check value of CurrentUICulture in base class and if it is sv then replace it with sv-SE Please correct me which one is right approach or Is there any other good way of doing?

• Valueurl Binding On Large Arrays Causes Sluggish User Interface

  - by Hooligancat

  I have a large data set (some 3500 objects) that returns from a remote server via HTTP. Currently the data is being presented in an NSCollectionView. One aspect of the data is a path pack to the server for a small image that represents the data (think thumbnail for simplicity). Bindings works fantastically for the data that is already returned, and binding the image via a valueurl binding is easy to do. However, the user interface is very sluggish when scrolling through the data set - which makes me think that the NSCollectionView is retrieving all the image data instead of just the image data used to display the currently viewable images. I was under the impression that Cocoa controls were smart enough to only retrieve data for the information that is actually being output to the user interface through lazy loading. This certainly seems to be the case with NSTableView - but I could be misguided on this thought. Should valueurl binding act lazily and, moreover, should it act lazily in an NSCollectionView? I could create a caching mechanism (in fact I already have such a thing in place for another application - see my post here if you are interested http://stackoverflow.com/questions/1740209/populating-nsimage-with-data-from-an-asynchronous-nsurlconnection) but I really don't want to go this route if I don't have to for this specific implementation as the user could potentially change data sets often and may only want small sub-sets of the data. Any suggested approaches? Thanks!

• Load external pages using jquery

  - by user1688011

  I'm trying to use jquery to load external pages into the current without reloading. Apparently everything works fine except of one little issue, I hope I'll be clear as much as possible. When I call the page 'info.php' it is loaded into the #content div. That's what the script supposed to do, the problem is that in the main page, which contains the script and the #content div, I already have some code that I want it to be executed when someone visit the page and not to be called from external page. That is actually the case but when I click on one of the links in the menu, I can't go back to the initial content.. <script> $(function() { $('#nav a').click(function() { var page = $(this).attr('href'); $('#content').load(page + '.php'); return false; }); }); </script> <ul id="nav"> <li><a href="#">Page1</a></li> <li><a href="about">About</a></li> <li><a href="contact">Contact</a></li> <li><a href="info">Info</a></li> </ul> <div id="content"> Here I have some code that I wanted to be attributed to the "Page1" </div> Do you have any suggestions how to fix this issue? Thanks

• Best way for launching html/jsp to communicate with GWT module

  - by h2g2java

  I asked this at the GWT forum but I'm impatient for the answer and I seem to get rather good responses here. A html or jsp file is used to launch the xxx.nocache.js, which then decides which browser "permutation" to use. <head> <meta http-equiv="content-type" content="text/html;charset=UTF-8"> <title>xxx</title> <script type="text/javascript" language="javascript" src="xxx.nocache.js"></script> </head> In my case, I am using a jsp. When the JSP is executed, it discovers some conditions. I wish to pass these conditions as values to the GWT module being launched. The "elegant" GWT way to pass these values would be to persist them as request/memcache attributes and then have the GWT module perform RPC to retrieve those values. For example, the JSP discovers that the current user is Whoopy. Shouldn't I simply have the JSP generate javascript to store user = "Whoopy" as a top or namedframe level javascript variable and use JSNI within the module to retrieve the value for user? I have not tried it yet, but I would like to know how anyone might have done it without having to use RPC.
