  • What's wrong with this 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

  • Axis webservice calls fail sometimes, access.log shows content!

    - by epischel
    Hi, our app is a webservice client (axis 1) to a third party webservice (also axis 1). We use it for some years now. Since a few weeks, we (as a client) get sometimes HTTP status 400 (bad request) or read timeouts when calling the webservice. Strangely, the access.log of the service shows part of the request or the response instead of the URL. It looks like this (looks like the end of the request string) x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 16127 0 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "POST /webservice HTTP/1.0" 200 22511 1 x.x.x.x -> y.y.y.y:8080 - - [timestamp] "il=\"true\"/><nsl:text xsi:type=\"xsd:string\" xsi:nil=\"true\"/></SOAPSomeOperation></soapenv:Body></soapenv:Envelope> Axis/1.4" 400 299 0 or (some string out of the what looks like the request) x.x.x.x -> y.y.y.y:8080 - - [timestamp] ":string\">some text</sometag><othertag>moretext" 400 299 0 or in some other cases it looks like two requests thrown together (... means xml string left out): x.x.x.x -> y.y.y.y:8080 - - [timestamp] "...</someop></soapenv:Body></soapenv:Envelope>:xsd=\"http://www.w3.org/2001/XMLSchema\"...</soapenv:Body></soapenv:Envelope>" 400 299 0 Application log does not give any hints. Frequency of such call is 1% of all calls to that service. The only discriminator I know of so far is that it happens since operations informed us that the service url changed because of "server migration". Has anyone experienced such phenomenon yet? Has somebody got an idea whats wrong and how to fix? Thanks,

  • SQLiteDataAdapter Update method returning 0

    - by Lirik
    I loaded 83 rows from my CSV file, but when I try to update the SQLite database I get 0 rows... I can't figure out what I'm doing wrong. The program outputs: Num rows loaded is 83 Num rows updated is 0 The source code is: public void InsertData(String csvFileName, String tableName) { String dir = Path.GetDirectoryName(csvFileName); String name = Path.GetFileName(csvFileName); using (OleDbConnection conn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + dir + @";Extended Properties=""Text;HDR=Yes;FMT=Delimited""")) { conn.Open(); using (OleDbDataAdapter adapter = new OleDbDataAdapter("SELECT * FROM " + name, conn)) { QuoteDataSet ds = new QuoteDataSet(); adapter.Fill(ds, tableName); Console.WriteLine("Num rows loaded is " + ds.Tags.Rows.Count); InsertData(ds, tableName); } } } public void InsertData(QuoteDataSet data, String tableName) { using (SQLiteConnection conn = new SQLiteConnection(_connectionString)) { using (SQLiteDataAdapter sqliteAdapter = new SQLiteDataAdapter("SELECT * FROM " + tableName, conn)) { using (new SQLiteCommandBuilder(sqliteAdapter)) { conn.Open(); Console.WriteLine("Num rows updated is " + sqliteAdapter.Update(data, tableName)); } } } } Any hints on why it's not updating the correct number of rows?

  • ERROR_MORE_DATA ---- Reading from Registry

    - by user314749
    I am trying to create an offline registry in memory using the offreg.dll provided in the windows ddk 7 package. You can find out more information on the offreg.dll here: MSDN Currently, while attempting to read a value from an open registry hive / key I receive the following error: 234 or ERROR_MORE_DATA Here is the .h code that contains ORGetValue: DWORD ORAPI ORGetValue ( __in ORHKEY Handle, __in_opt PCWSTR lpSubKey, __in_opt PCWSTR lpValue, __out_opt PDWORD pdwType, __out_bcount_opt(*pcbData) PVOID pvData, __inout_opt PDWORD pcbData ); Here is the code that I am using to pull the data [DllImport("offreg.dll", CharSet = CharSet.Auto, EntryPoint = "ORGetValue", SetLastError = true, CallingConvention = CallingConvention.StdCall)] public static extern uint ORGetValue(IntPtr Handle, string lpSubKey, string lpValue, out uint pdwType, out string pvData, out uint pcbData); IntPtr myHive; IntPtr myKey; string myValue; uint pdwtype; uint pcbdata; uint ret3 = ORGetValue(myKey, "", "DefaultUserName", out pdwtype, out myValue, out pcbdata); The goal is to be able to read myValue as a string. I am not sure if I need to use marshaling... or a second call with an adjusted buffer.. Or really how to adjust the buffer in C#. Any help or pointers would be greatly appreciated. Thank you.

  • 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?

  • Java Iterators - Trying to get a for each loop to work

    - by CS Student
    So I have a Tree<E> class where E is the datatype held and organized by the tree. I'd like to iterate through the Tree like this, or in a way similar to this: 1. Tree<String> tree=new Tree<String>(); 2. ...add some nodes... 3. for (String s : tree) 4. System.out.println(s); It gives me an error on line 3 though. Incompatible types required: java.lang.String found: java.lang.Object The following works fine and as expected though, performing a proper in-order traversal of the tree and printing each node out as it should: for (TreeIterator<String> i = tree.iterator(); i.hasNext(); ) System.out.println(i.next()); Any idea what I'm doing wrong? Do you need to see more of the code?

    Hi i want to do some validations.I used to put regex in JS but im new to regex in java, so i tried to make up a code on similar lines in java. Here is what i did. 1)Check whether first character in string is alphanumeric. 2)Check whether the string atleast 1 number. so i wrote a code, but it is always returning false.I am not sure if i'm doing this correctly. private static boolean checkEmbeddedPassword(final String field) { boolean returnValue=true; String testpatternAlpha="/^[A-Za-z0-9].+$/"; String testNumber="/[0-9]/"; Pattern pattern=Pattern.compile(testpatternAlpha); Pattern pattern2=Pattern.compile(testNumber); Matcher matcher = pattern.matcher(field); Matcher matcher2 = pattern2.matcher(field); boolean firstChar=matcher.matches(); boolean numberFlag=matcher2.matches(); System.out.println("-----the value of pwd iss-----"+field); System.out.println("---------Regex---------Out--put-----"+firstChar); System.out.println("---------Regex---------Out- for numeral-put-----"+numberFlag); if(firstChar){ returnValue=false; } else if(field.contains(" ")) { System.out.println("-----------cannot have space------"); returnValue=false; } else if(numberFlag) { returnValue=false; } return returnValue; }

  • 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.

  • Changing property type in class that implements interface with object type property.

    - by used2could
    I know the title is a bit confusing but bare with me. (I'm up for suggestions on a new title lol) I'm writing a TemplateEngine that will allow me to use my own markup in text based files. I'm wanting to add controls as plugins as the application matures. Currently i've got a structure like the following: interface IControl string Id object Value class Label : IControl string Id string Value class Repeater : IControl string Id List<IControl> Value Now you'll see the strange part right away in the Repeater class with the Value property. I was hoping that having the Value type as object in the interface would allow me the flexibility to expand the controls as i go along. The compiler doesn't like this and for good reason i guess. Does anyone have any suggestions how to accomplish this? Note: Please don't go into suggesting things like use Spark View Engine for templating. There is a reason i'm creating extra work for myself.

  • 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?

  • 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; }

  • 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 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?

  • How to write a Custom DesignerSerializer for an class used by a Activity (WF)

    - by Stefan Steinegger
    I have a type which is used in a WF activity. It should be serialized. It doesn't work out of the box, most probably because of the private setters in that type. I'm not sure if this is the correct way, but I tried to write my own serializer and declared it on my class. [DesignerSerializer( typeof(FooDesignerSerializer), // my custom serializer typeof(WorkflowMarkupSerializer))] public class Foo { public Foo(int value, string name { // ... } public int Value { get; private set; } public string Name { get; private set; } } Is this the easiest way to get it serialized? How do I write this serializer? That's what I got so far: public class FooDesignerSerializer : WorkflowMarkupSerializer { protected override string SerializeToString( WorkflowMarkupSerializationManager serializationManager, object value) { // how to create a valid / XOML-like string? } }

  • ASP MVC: Custom Validation Attribute

    - by user323395
    I'm trying to write my own Custom Validation attribute but i'm having some problems. The attribute i'm trying to write is that when a user logs in, the password will be compared against the confirmation password. namespace EventCompanion.Data.Attributes { public class ComparePassword : ValidationAttribute { public string PasswordToCompareWith { get; set; } public override bool IsValid(object value) { if (PasswordToCompareWith == (string)value) { return true; } return false; } } Now my problem is when i'm trying to set the attribute like this in the model file: [Required] [ComparePassword(PasswordToCompareWith=ConfirmPassword)] public string Password { get; set; } [Required] public string ConfirmPassword { get; set; } } I get the following error: Error 1 An object reference is required for the non-static field, method, or property 'Project.Data.Models.GebruikerRegistreerModel.ConfirmPassword.get' It seems that VS is not accepting the confirmpassword in the "PasswordToCompareWith=ConfirmPassword" part Now my question: What am i doing wrong? Thanks in advance!!!
