• Problem pulling data from website in .NET and C#

  - by Cptcecil

  I have written a web scraping program to go to a list of pages and write all the html to a file. The problem is that when I pull a block of text some of the characters get written as '?'. How do I pull those characters into my text file? Here is my code: string baseUri = String.Format("http://www.rogersmushrooms.com/gallery/loadimage.asp?did={0}&blockName={1}", id.ToString(), name.Trim()); // our third request is for the actual webpage after the login. HttpWebRequest request = (HttpWebRequest)WebRequest.Create(baseUri); request.Method = "GET"; request.UserAgent = "Mozilla/4.0 (compatible; MSIE 8.0; Windows NT 6.1)"; //get the response object, so that we may get the session cookie. HttpWebResponse response = (HttpWebResponse)request.GetResponse(); StreamReader reader = new StreamReader(response.GetResponseStream()); // and read the response string page = reader.ReadToEnd(); StreamWriter SW; string filename = string.Format("{0}.txt", id.ToString()); SW = File.AppendText("C:\\Share\\" + filename); SW.Write(page); reader.Close(); response.Close();

• Receiving generic typed <T> custom objects through remote object in Flex

  - by Aaron

  Is it possible to receive custom generic typed objects through AMF? I'm trying to integrate a flex app with an existing C# service but flex is choking on custom generic typed objects. As far as I can tell Flex doesn't even support generics, but I'd like to be able to even just read in the object and cast its members as necessary. I basically just want flex to ignore the <T>. I'm hopeful that there's a way to do this, since flex doesn't complain about typed collections (a server call returning List works fine and flex converts it to an ArrayCollection just like an un-typed List). Here's a trimmed down example of what's going on for me: The custom C# typed class public class TypeTest<T> { public T value { get; set; } public TypeTest () { } } The server method returning the typeTest public TypeTest<String> doTypeTest() { TypeTest<String> theTester = new TypeTest<String>("grrrr"); return theTester; } The corresponding flex value object: [RemoteClass(alias="API.Model.TypeTest")] public class TypeTest { private var _value:Object; public function get value():Object { return _value; } public function set value(theValue:Object):void { _value = value; } public function TypeTest() { } } and the result handler code: public function doTypeTest(result:TypeTest):void { var theString:String = result.value as String; trace(theString); } When the result handler is called I get the runtime error: TypeError: Error #1034: Type Coercion failed: cannot convert mx.utils::ObjectProxy@11a98041 to com.model.vos.TypeTest. Irritatingly if I change the result handler to take parameter of type Object it works fine. Anyone know how to make this work with the value object? I feel like i'm missing something really obvious.

• Good way to maintain Muliple level selection menu list in J2ME

  - by geoaxis

  Hello, I need a good way to maintain multiple form level data for menue selection. So for example If I have A and B, each might Have 1 2 3 so A A1 A2 A3 B B1 B2 B3 And this can continue for long, so that I could have A - A1 - A1.1 - A1.1.1 -.... I have the following class in place, works ok But I suspect we could have better. I just need to perform selection ni a selection tree like Widget, but each level of selection comes in another form (in J2ME) import java.util.Vector; public class Tag { private String tag; private Vector childTags; private Tag parent; Tag(String tag, Vector childtag) { this.tag = tag; this.childTags= childTags; } public void setChildTags(Vector childTags) { this.childTags = childTags; } public Vector getChildTags() { return this.childTags; } public String getTag() { return this.tag; } public String toString(int depth) { String a =""; if(depth==0) { a = a + this.getTag(); } if(this.getChildTags()!= null) { for(int k=0;k <this.getChildTags().capacity(); k++) { for (int i=0; i<depth; i++ ) { a = a + ("-"); } a = a+ ( ((Tag)this.getChildTags().elementAt(k)).toString(depth++)); } } return a; } }

• Prevent SQL Injection in Dynamic column names

  - by Mr Shoubs

  I can't get away without writing some dynamic sql conditions in a part of my system (using Postgres). My question is how best to avoid SQL Injection with the method I am currently using. EDIT (Reasoning): There are many of columns in a number of tables (a number which grows (only) and is maintained elsewhere). I need a method of allowing the user to decide which (predefined) column they want to query (and if necessary apply string functions to). The query itself is far too complex for the user to write themselves, nor do they have access to the db. There are 1000's of users with varying requirements and I need to remain as flexible as possible - I shouldn't have to revisit the code unless the main query needs to change - Also, there is no way of knowing what conditions the user will need to use. I have objects (received via web service) that generates a condition (the generation method is below - it isn't perfect yet) for some large sql queries. The _FieldName is user editable (parameter name was, but it didn't need to be) and I am worried it could be an attack vector. I put double quotes (see quoted identifier) around the field name in an attempt to sanitize the string, this way it can never be a key word. I could also look up the field name against a list of fields, but it would be difficult to maintain on a timely basis. Unfortunately the user must enter the condition criteria, I am sure there must be more I can add to the sanatize method? and does quoting the column name make it safe? (my limited testing seems to think so). an example built condition would be "AND upper(brandloaded.make) like 'O%' and upper(brandloaded.make) not like 'OTHERBRAND'" ... Any help or suggestions are appreciated. Public Function GetCondition() As String Dim sb As New Text.StringBuilder 'put quote around the table name in an attempt to prevent some sql injection 'http://www.postgresql.org/docs/8.2/static/sql-syntax-lexical.html sb.AppendFormat(" {0} ""{1}"" ", _LogicOperator.ToString, _FieldName) Select Case _ConditionOperator Case ConditionOperatorOptions.Equals sb.Append(" = ") ... End Select sb.AppendFormat(" {0} ", Me.UniqueParameterName) 'for parameter Return Me.Sanitize(sb) End Function Private Function Sanitize(ByVal sb As Text.StringBuilder) As String 'compare against a similar blacklist mentioned here: http://forums.asp.net/t/1254125.aspx sb.Replace(";", "") sb.Replace("'", "") sb.Replace("\", "") sb.Replace(Chr(8), "") Return sb.ToString End Function Public ReadOnly Property UniqueParameterName() As String Get Return String.Concat(":" _UniqueIdentifier) End Get End Property

• JSF 2 f:ajax lifecycle problem

  - by gerry

  The problem is, that if a property is changed during an f:ajax request and a binded panelGroup should be newly created depending on that changed value, the old value is used. This code will explain the problem. Here is the backingbean TestBean: public String getFirst() { return first; } public void setFirst(String first) { this.first = first; } public String getLast() { return last; } public void setLast(String last) { this.last = last; } public String getName(){ return first+" "+last; } public void setDynamicPanel(HtmlPanelGroup panel){ } public HtmlPanelGroup getDynamicPanel(){ Application app = FacesContext.getCurrentInstance().getApplication(); HtmlPanelGroup component = (HtmlPanelGroup)app.createComponent(HtmlPanelGroup.COMPONENT_TYPE); HtmlOutputLabel label1 = (HtmlOutputLabel)app.createComponent(HtmlOutputLabel.COMPONENT_TYPE); label1.setValue(" --> "+getFirst()+" "+getLast()); component.getChildren().add(label1); return component; } and now the jsf/facelet code: <h:form id="form"> <h:panelGrid columns="1"> <h:inputText id="first" value="#{testBean.first}" /> <h:inputText id="last" value="#{testBean.last}" /> <h:commandButton value="Show"> <f:ajax execute="first last" render="name dyn" /> </h:commandButton> </h:panelGrid> <h:outputText id="name" value="#{testBean.name}" /> <h:panelGroup id="dyn" binding="#{testBean.dynamicPanel}" /> </h:form> After the page was initially loaded the outputText and panelGroup shows both "null" as first and last. But after the button is pressed, the outputText is updated well, but the the panelgroup shows again only "null". This is due to the problem, that the "binded method" dynamicPanel is executed before the update of the first and last properties. how can workaround this behaviour or what is wrong with my code?

• extend web server to serve static files

  - by Turtle

  Hello, I want to extend a web server which is only able to handle RPC handling now. The web server is written in C#. It provides a abstract handler function like following: public string owsHandler(string request, string path, string param, OSHttpRequest httpRequest, OSHttpResponse httpResponse) And I wrote following code to handle image files: Bitmap queryImg = new Bitmap(path); System.IO.MemoryStream stream = new System.IO.MemoryStream(); queryImg.Save(stream, System.Drawing.Imaging.ImageFormat.Bmp); queryImg.Dispose(); byte[] byteImage = stream.ToArray(); stream.Dispose(); return Convert.ToBase64String(byteImage); And I test it in the browser, the image is returned but the image dimension info is missed. Shall I add something more to the code? Or is any general way to server static files? I do not want to serve it in a ASP.net server. Thanks

• How to do call function after client finishes download from tornado web server?

  - by Shabbyrobe

  I would like to be able to run some cleanup functions if and only if the client successfully completes the download of a file I'm serving using Tornado. I installed the firefox throttle tool and had it slow the connection down to dialup speed and installed this handler to generate a bunch of rubbish random text: class CrapHandler(BaseHandler): def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) print "done" I get the following output from tornado immediately after making the request: done I 100524 19:45:45 web:772] 200 GET /123 (192.168.45.108) 195.10ms The client then plods along downloading for about 20 seconds. I expected that it would print "done" after the client was done. Also, if I do the following I get pretty much the same result: class CrapHandler(BaseHandler): @tornado.web.asynchronous def get(self, token): crap = ''.join(random.choice(string.ascii_uppercase + string.digits) for x in range(100000)) self.write(crap) self.finish() print "done" Am I missing something fundamental here? Can tornado even support what I'm trying to do? If not, is there an alternative that does?

• int.Parse of "8" fails. int.Parse always requires CultureInfo.InvariantCulture?

  - by Henrik Carlsson

  We develop an established software which works fine on all known computers except one. The problem is to parse strings that begin with "8". It seems like "8" in the beginning of a string is a reserved character. Parsing: int.Parse("8") -> Exception message: Input string was not in a correct format. int.Parse("80") -> 0 int.Parse("88") -> 8 int.Parse("8100") -> 100 CurrentCulture: sv-SE CurrentUICulture: en-US The problem is solved using int.Parse("8", CultureInfo.InvariantCulture). However, it would be nice to know the source of the problem. Question: Why do we get this behaviour of "8" if we don't specify invariant culture? Additional information: I did send a small program to my client achieve the result above: private int ParseInt(string s) { int parsedInt = -1000; try { parsedInt = int.Parse(s); textBoxMessage.Text = "Success: " + parsedInt; } catch (Exception ex) { textBoxMessage.Text = string.Format("Error parsing string: '{0}'", s) + Environment.NewLine + "Exception message: " + ex.Message; } textBoxMessage.Text += Environment.NewLine + Environment.NewLine + "CurrentCulture: " + Thread.CurrentThread.CurrentCulture.Name + "\r\n" + "CurrentUICulture: " + Thread.CurrentThread.CurrentUICulture.Name + "\r\n"; return parsedInt; }

• library to determine indefinite article of a noun

  Are there any libraries for .NET that deal with determining the Indefinite Article of a noun? My crude attempt is below, which will probably work for 99% of my usage (which is acceptable) just wondering if there are any established alternatives? public static string GetIndefinateArticle(string noun) { if(string.IsNullOrEmpty(self)) return self; var first = noun[0]; if(first == 'a' || first == 'e' || first == 'i' || first == 'o') return "a " + self; return "an " + self; }

• Compile IL code at runtime using .NET 3.5 and C# from file

  - by nitefrog

  I would like to take a file that is an IL file, and at run time compile it back to an exe. Right now I can use process.start to fire off the command line with parameters (ilasm.exe) but I would like to automate this process from a C# service I will create. Is there a way to do this with reflection and reflection.emit? While this works: string rawText = File.ReadAllText(string.Format("c:\\temp\\{0}.il", Utility.GetAppSetting("baseName")), Encoding.ASCII); rawText = rawText.Replace("[--STRIP--]", guid); File.Delete(string.Format("c:\\temp\\{0}.il", Utility.GetAppSetting("baseName"))); File.WriteAllText(string.Format("c:\\temp\\{0}.il", Utility.GetAppSetting("baseName")),rawText, Encoding.ASCII); pi = new ProcessStartInfo(); pi.WindowStyle = ProcessWindowStyle.Hidden; pi.FileName = "\"" + ilasm + "\""; pi.Arguments = string.Format("c:\\temp\\{0}.il", Utility.GetAppSetting("baseName")); using(Process p = Process.Start(pi)) { p.WaitForExit(); } It is not ideal as I really would like this to be a streamlined process. I have seen examples of creating the IL at runtime, then saving, but I need to use the IL I already have in file form and compile it back to an exe. Thanks.

• If statement is ignored

  - by user2898120

  I am making a simple matchmaker as a learning project in JAVA. My program so far just asks a few questions, but I wanted to do gender specific questions, so I asked for their sex (m or f) and then attempted to add a message that only showed if sex was m. The dialog should say "well done, you are male!". Else it restarts method. Every time, no matter what I type it restarts the program. Here is my code: import javax.swing.JOptionPane; public class Main { public static void main(String[] args){ setVars(); } public static void setVars(){ String name = JOptionPane.showInputDialog(null, "What is your name?"); String sAge = JOptionPane.showInputDialog(null, "What is your age?"); String sex = JOptionPane.showInputDialog(null, "What is your sex?\n(Enter m or f)"); if (sex == "m"){ JOptionPane.showMessageDialog(null, "Well done, you are male.\nKeep Going!"); } int age = Integer.parseInt(sAge); String chars = JOptionPane.showInputDialog(null, "Name three charectaristics"); } }

• trying to read a delimited text file from resources - but it wont run

• JOptionPane opening another JFrame

  - by mike_hornbeck

  So I'm continuing my fight with this : http://stackoverflow.com/questions/2923545/creating-java-dialogs/2926126 task. Now my JOptionPane opens new window with envelope overfiew, but I can't change size of this window. Also I wanted to have sender's data in upper left corner, and receiver's data in bottom right. How can I achieve that ? There is also issue with OptionPane itself. After I click 'OK' it opens small window in the upper left corner of the screen. What is this and why it's appearing ?

• How to do a search from a list with non-prefix keywords

  - by aNui

  First of all, sorry if my english or my post got any mistakes. I am programming a program to search the name from the list and I need to find them if the keyword is not in front of the names (that's what I mean non-prefix) e.g. if I my list is the music instruments and I type "guit" to the search textbox. It should find the names "Guitar, Guitarrón, Acoustic Guitar, Bass Guitar, ..." or something like this Longdo Dictionary's search suggestion. here is my simple and stupid algorithm (that's all I can do) const int SEARCHROWLIMIT = 30; private string[] DoSearch(string Input, string[] ListToSearch) { List<string> FoundNames = new List<string>(); int max = 0; bool over = false; for (int k = 0; !over; k++) { foreach (string item in ListToSearch) { max = (max > item.Length) ? max : item.Length; if (k > item.Length) continue; if (k >= max) { over = true; break; } if (!Input.Equals("Search") && item.Substring(k, item.Length - k).StartsWith(Input, StringComparison.OrdinalIgnoreCase)) { bool exist = false; int i = 0; while (!exist && i < FoundNames.Count) { if (item.Equals(FoundNames[i])) { exist = true; break; } i++; } if (!exist && FoundNames.Count < SEARCHROWLIMIT) FoundNames.Add(item); else if (FoundNames.Count >= SEARCHROWLIMIT) over = true; } } } return FoundNames.ToArray(); } I think this algorithm is too slow for a large number of names and after several trial-and-error, I decided to add SEARCHROWLIMIT to breaks the operation And I also think there're some readymade methods that can do that. And another problem is I need to search music instruments by a category like strings, percussions, ... and by the country of origins. So I need to search them with filter by type and country. please help me. P.S. Me and my friends are just student from Thailand and developing the project to compete in Microsoft Imagine Cup 2010 and please become fan on our facebook page [KRATIB][3]. And we're so sorry we don't have much information in English but you can talk to us in English.

• How to use pure in D 2.0

  - by James Dean

  While playing around with D 2.0 I found the following problem: Example 1: pure string[] run1() { string[] msg; msg ~= "Test"; msg ~= "this."; return msg; } This compiles and works as expected. When I try to wrap the string array in a class I find I can not get this to work: class TestPure { string[] msg; void addMsg( string s ) { msg ~= s; } }; pure TestPure run2() { TestPure t = new TestPure(); t.addMsg("Test"); t.addMsg("this."); return t; } This code will not compile because the addMsg function is impure. I can not make that function pure since it alters the TestPure object. Am i missing something? Or is this a limitation? The following does compile: pure TestPure run3() { TestPure t = new TestPure(); t.msg ~= "Test"; t.msg ~= "this."; return t; } Would the ~= operator not been implemented as a impure function of the msg array? How come the compiler does not complain about that in the run1 function?

• ASP.NET MVC Cookie loses value when page is changed

  - by Jova

  When a user logs in to my site, I create a cookie with some info in it. However, whenever they change page from logging in, the cookie loses it's value. Cookie is still there but it's empty. I've checked my code and the cookie doesn't get rewritten by anything I've done. Does anyone have any idea to why the cookie becomes empty when the page is changed?

• Using java.util.regex in Android apps - are there issues with this?

  - by johnrock

  In an Android app I have a utility class that I use to parse strings for 2 regEx's. I compile the 2 patterns in a static initializer so they only get compiled once, then activities can use the parsing methods statically. This works fine except that the first time the class is accessed and loaded, and the static initializer compiles the pattern, the UI hangs for close to a MINUTE while it compiles the pattern! After the first time, it flies on all subsequent calls to parseString(). My regEx that I am using is rather large - 847 characters, but in a normal java webapp this is lightning fast. I am testing this so far only in the emulator with a 1.5 AVD. Could this just be an emulator issue or is there some other reason that this pattern is taking so long to compile? private static final String exp1 = "(insertratherlong---847character--regexhere)"; private static Pattern regex1 = null; private static final String newLineAndTagsExp = "[<>\\s]"; private static Pattern regexNewLineAndTags = null; static { regex1 = Pattern.compile(exp1, Pattern.CASE_INSENSITIVE); regexNewLineAndTags = Pattern.compile(newLineAndTagsExp); } public static String parseString(CharSequence inputStr) { String replacementStr = "replaceMentText"; String resultString = "none"; try { Matcher regexMatcher = regex1.matcher(inputStr); try { resultString = regexMatcher.replaceAll(replacementStr); } catch (IllegalArgumentException ex) { } catch (IndexOutOfBoundsException ex) { } } catch (PatternSyntaxException ex) { } return resultString; }
