  • Axis2 issue with comment in WSDL

    - by Sirs
    I'm using an Axis2 client to access an external Webservice, whose WSDL starts with the following content: <?xml version="1.0" encoding="UTF-8"?><!--Created by TIBCO WSDL--><wsdl:definitions xmlns:wsdl=... My call to sendReceive crashes with the following error: com.ctc.wstx.exc.WstxUnexpectedCharException: Unexpected character 'C' (code 67) in prolog; expected '<' The 'C' is the first character on the comment in the WSDL. Without that comment everything works fine, but as far as my knowledge of basic XML dictates that comment is correct. My question would be: Is this a bug in Axis2 or is the accessed WSDL malformed? Is there any way to prevent Axis2 from crashing under these circumstances?

  • Netlogo behaviorspace, How to export each experiment's plot in a separate directory with a unique name? (Answer is by using pathdir extension)

    - by Marzy
    I have a save-plots function which I call it in my final command of behavior space to export selected plots, I could create unique names for plots so they don't replace each other, for example my output file name for one of the plots is like this: DeathRates, PS true, HCHA false 100,true.csv Let FileNameDeathRates ( word "D: /Results/" "DeathRates, " "PS "PS? ", HCHA " HCHA? MPS "," CV? ".csv" ) So far is good, but I want is to have a directory with name of the experiment and export all plots of that experiment in that directory for example: Let DirName( word "D:/Results/" "PS "PS? ", HCHA " HCHA? MPS "," CV? ) Netlogo already exports plots with proper name and I just want the directory name to be different , and of course prior to the experiment the directory does not exist so the directory should be created first , I could not find a command to create a directory in netlogo without pathdir extension. Any idea on how can I do this? Thanks in advance ;)

  • How can I fix the scroll bug when using Windows rich edit controls in wxpython?

    - by ChrisD
    When using wx.TextCtl with the wx.TE_RICH2 option in windows, I get this strange bug with the auto-scroll when using the AppendText function. It scrolls so that all the text is above the visible area, which isn't very useful behaviour. I tried just adding a call to ScrollLines(-1) after appending the text - which does scroll it to the correct position - but this can lead to the window flashing when it auto-scrolls. So I'm looking for another way to automatically scroll to the bottom. So far, my solution is to bypass the AppendText functions auto-scroll and implement my own, like this: def append_text(textctrl, text): before_number_of_lines = textctrl.GetNumberOfLines() textctrl.SetInsertionPointEnd() textctrl.WriteText(text) after_number_of_lines = textctrl.GetNumberOfLines() textctrl.ScrollLines(before_number_of_lines - after_number_of_lines + 1) Is there a better way?

  • Why does my app crash when I add an row to the table view?

    - by mystify
    I'm adding a row like this, when a button is pressed. It must be the very first row in the first section: NSIndexPath *indexPath = [NSIndexPath indexPathForRow:0 inSection:0]; [self insertRowsAtIndexPaths:[NSArray arrayWithObject:indexPath] withRowAnimation:UITableViewRowAnimationFade]; I don't call anything else here. No -reloadData. I keep getting this: * Terminating app due to uncaught exception 'NSInternalInconsistencyException', reason: 'Invalid update: invalid number of rows in section 0. The number of rows contained in an existing section after the update (6) must be equal to the number of rows contained in that section before the update (6), plus or minus the number of rows inserted or deleted from that section (1 inserted, 0 deleted).'

  • Anyone got Twitter xAuth working with the Compact Framework yet?

    - by peSHIr
    This question is related to a number of other questions on oAuth on the Compact Framework (one, two) but seems slightly more specific to me, as it specifically involves getting Twitters xAuth API call (meant for non web applications to be able to do oAuth) working on the Compact Framework. Are SSL HTTP connections and the encryption methods needed for xAuth needed part of Compact Framework 3.5? Did anyone get the Twitter xAuth working on Windows Mobile already? If so, what libraries did you use for this? Any tips are welcome.

  • PHP Image Link in FUnction 404's

    - by Dave C
    Hello, I have a valid link that goes to a picture located on my web server. It is a simple jpg image, I can copy and paste this link into my web browser and it loads fine. The issue comes in when I try to call a few php functions on the image... such as getimagesize or fopen... they both return 404 errors even though the image is there. Does anyone know that could be causing this? Thank you for your time.

  • Win32 select/poll/eof/ANYTHING!?!?!

    - by Andrew
    Using the standard Win32 file I/O API's (CreateFile/ReadFile/etc), I'm trying to wait for a file to become readable, or for an exception to occur on the file. If Windows had any decent POSIX support, I could just do: select(file_count, files_waiting_for_read, NULL, files_waiting_for_excpt, NULL, NULL); And select will return when there's anything interesting on some of the files. Windows doesn't support select or poll. Fine. I figured I could take the file and do something like: while(eof(file_descriptor)) { Sleep(100); } The above loop would exit when more data is available to be read. But nope, Windows doesn't have an equivalent of eof() either! I could possibly call ReadFile() on the file, and determine if it's at the eof that way. But, then I'd have to handle the reading at that point in time -- I'm hoping to simply be able to figure out that a file is readable, without actually reading it. What are my options?

  • Passing variables to callback functions

    - by mickyjtwin
    I am trying to write a jQuery plugin, that can be applied to a selector. Within this plugin, there are multiple calls to webservices, where callback methods are required. The problem I am having is maintaining the current context item in the each loop of the selector. (function($){ $.fn.myMethod = function(){ return this.each(function(){ var c = $(this); $.api.methodToCall("", CallbackFunction); }); }; function CallbackFunction(data, result){ // do stuff based on c } })(jQuery); Normally, you would provide the callback function straight away, which allows me to access c, however within the callback function, there potentially is another api call, so it would start to get messy. Is there any way to do this?

  • How to change the text color in a disabled edit box using MFC?

    - by anand.arumug
    Hello all, I have a dialog in which the edit box is disabled but the text should be displayed in red instead of the default grey. I tried the following: void CMyEdit::OnEnable(BOOL bEnable) { CEdit::OnEnable(bEnable); if (bEnable) { m_BackGroundColor = kRGBWhite; } else { m_BackGroundColor = kRGBDefaultGray; } m_TextColor = kRGBRed; m_BackgroundBrush.DeleteObject(); m_BackgroundBrush.CreateSolidBrush(m_BackGroundColor); Invalidate(); } But its still displaying the text in grey only. But if I remove the base class call CEdit::OnEnable(bEnable); then new text color takes effect. Can anyone explain whats wrong in the code? Thanks for your time. cheers...

  • Emulate clicking a link with Javascript that works with IE

    - by Tam
    I want to have java script clicking a link on the page..I found something on the net that suggests adding a function like this: function fireEvent(obj,evt){ var fireOnThis = obj; if( document.createEvent ) { var evObj = document.createEvent('MouseEvents'); evObj.initEvent( evt, true, false ); fireOnThis.dispatchEvent(evObj); } else if( document.createEventObject ) { fireOnThis.fireEvent('on'+evt); } } Then call it using: fireEvent(document.getElementById('edit_client_link'),'click'); This seems to work fine for FF but with IE it doesn't work! Any ideas?

  • Why no ArgumentEmptyException in .NET ?

    - by Andrei Rinea
    I am beginning to think I am doing something wrong. I mean they did place System.String.IsNullOrWhitespace finally but no ArgumentEmptyException class. public FilterItem(string name, IEnumerable<string> extensions) { if (string.IsNullOrWhiteSpace(name)) { throw new ArgumentNullException("name"); } if (extensions == null) { throw new ArgumentNullException("extensions"); } if (extensions.Count() == 0) { throw new ArgumentOutOfRangeException("extensions"); } this.Name = name; this.Extensions = extensions; } throwing an ArgumentOutOfRangeException feels unnatural. Also an instance of ArgumentException is too general in my opinion. It's easy to me to create a new exception class call it this way and have it over with. What bugs me is that it's not in the BCL/FCL and I am beginning to think there's a good reason not to have it. Should there be one?

  • How sophisticated should be DAL?

    - by Andrew Florko
    Basically, DAL (Data Access Layer) should provide simple CRUD (Create/Read/Update/Delete) methods but I always have a temptation to create more sophisticated methods in order to minimize database access roundtrips from Business Logic Layer. What do you think about following extensions to CRUD (most of them are OK I suppose): Read: GetById, GetByName, GetPaged, GetByFilter... e.t.c. methods Create: GetOrCreate methods (model entity is returned from DB or created if not found and returned), Create(lots-of-relations) instead of Create and multiple AssignTo methods calls Update: Merge methods (entities list are updated, created and deleted in one call) Delete: Delete(bool children) - optional children delete, Cleanup methods Where do you usually implement Entity Cache capabilities? DAL or BLL? (My choice is BLL, but I have seen DAL implementations also) Where is the boundary when you decide: this operation is too specific so I should implement it in Business Logic Layer as DAL multiple calls? I often found insufficient BLL operations that were implemented in dozen database roundtrips because developer was afraid to create a bit more sophisticated DAL. Thank you in advance!

  • ProviderException: InvalidCastException

    - by JS
    Few of our clients are regularly getting invalid cast exception, with variations i.e. InvalidCastException / ProviderException, but both generating from method call: System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) The other variation is: Exception type: InvalidCastException Exception message: Unable to cast object of type System.Int32 to type System.String. I had a look at application event log which shows: Stack trace: at System.Web.Security.SqlRoleProvider.GetRolesForUser(String username) at System.Web.Security.RolePrincipal.IsInRole(String role) at System.Web.Configuration.AuthorizationRule.IsTheUserInAnyRole(StringCollection roles, IPrincipal principal) at System.Web.Configuration.AuthorizationRule.IsUserAllowed(IPrincipal user, String verb) at System.Web.Configuration.AuthorizationRuleCollection.IsUserAllowed(IPrincipal user, String verb) at System.Web.Security.UrlAuthorizationModule.OnEnter(Object source, EventArgs eventArgs) at System.Web.HttpApplication.SyncEventExecutionStep.System.Web.HttpApplication.IExecutionStep.Execute() at System.Web.HttpApplication.ExecuteStep(IExecutionStep step, Boolean& completedSynchronously)* Has anyone come across this issue, and if so what is the fix?

  • How to handle redirection in an Ajax based application

    - by nimo
    hi all, I'm developing a Ajax based php application. As anybody knows, I'm checking whether user is logged in every php file as the first statement. And there are two ways that I should response in an event of logging failure, server redirect to the login page using header(url). CASE: If user directly enter a particular URL passing url in Ajax response asking client side page redirection or notification CASE: If user trying to perform some action through a Ajax request So my question is how can identify whether request coming from client side is a Ajax call or not ? If I know that I can handle my response accordingly. OR Is there a better way of handling above scenario ? Thank You

  • Do a database query on Textbox onblur event

    - by user279521
    I am using asp.net 3.5 with C#. I need to do a database lookup when a user enters ProductID in txtProductID. I guess doing javascript is out of the question since this will have to be server side call. I wrote this code in the page_load event of the webpage: protected void Page_Load(object sender, EventArgs e) { txtProductID.Attributes.Add("onblur", "LookupProduct()"); } protected void LookupUser() { //Lookup Product information on onBlur event; } I get an error message: Microsoft JScript runtime error: Object expected How can I resolve this ?

  • How do I draw the desktop on Mac OS X?

    - by Dominic Cooney
    I want to draw the desktop on Mac OS X (Snow Leopard). Specifically, I want to achieve the same effect as running: /System/Library/Frameworks/ScreenSaver.framework/Resources/ ScreenSaverEngine.app/Contents/MacOS/ScreenSaverEngine -background (If you’re not near your computer, this displays the screensaver where you would normally see your desktop background.) I know how to make a window without a border (by subclassing NSWindow and overriding initWithContentRect:styleMask:backing:defer: to set the window style to NSBorderlessWindowMask) and without a shadow (setHasShadow:NO.) I know that I can call setLevel:kCGDesktopWindowLevel or kCGDesktopIconWindowLevel to put my window below other windows (see question 418791.) However this isn’t exactly what I want, because a window at this level is still on top of the desktop icons. I want to be on top of the desktop background, but below the icons. My view is opaque. If there is a technique that clobbers the desktop background, that is OK.

  • VB.net: Is my Thread Safe List Solution actually safe?

    - by Shiftbit
    I've added teh following Extensions to my Project in order to create a thread safe list: Extensions If I want to conduct a simple operation on my list <Extension()> _ Public Sub Action(Of T)(ByVal list As List(Of T), ByVal action As Action(Of List(Of T))) SyncLock (list) action(list) End SyncLock End Sub If I want to pass it more than one parameter I could simply extend it with more items... <Extension()> _ Public Sub Action(Of T)(ByVal list As List(Of T), ByVal action As Action(Of List(Of T), T), ByVal item As T) SyncLock (list) Action(list, item) End SyncLock End Sub Actions I have created the following Action Examples: Private Sub Read(Of T)(ByVal list As List(Of T)) Console.WriteLine("Read") For Each item As T In list Console.WriteLine(item.ToString) Thread.Sleep(10) Next End Sub and also one that takes a parameter: Private Sub Write(Of T)(ByVal list As List(Of T), ByVal item As T) Thread.Sleep(100) list.Add(item) Console.WriteLine("Write") End Sub Initiating Then in my various threads I will call my Actions with: list.Action(AddressOf Read) or list.Action(AddressOf Write2, 10) Are these Extenxion methods thread safe or do you have other recommendations?

  • Home Pages in ASP.NET MVC

    - by Maxim Z.
    I'm trying out ASP.NET MVC, but, after reading a huge tutorial, I'm slightly confused. I understand how Controllers have Actions that URLs are routed to, but how do home pages work? Is the home page its own controller (e.g. "Home") that has no actions? This sounds correct, but how is it functionality implemented without Actions (no Actions means no methods that call the View Engine)? In other words, my question is this: how are home pages implemented (in terms of Controllers and Views)? Could you please provide sample code?

  • MSXML2.ServerXMLHTTP.4.0 Source?

    - by Frank V
    Where does the object "MSXML2.ServerXMLHTTP.4.0" come from? Which install package? I'm attempting to do the following: Set oXMLHTTP = CreateObject("MSXML2.ServerXMLHTTP.4.0") This attempt fails on my development machine (no object is returned) but it is successful on my collage's development machine. Obviously he has something installed that I don't or vice versa but where does this object, dll, etc come from? What would I need to install to get this call to work. For the record, changing the object to a different version isn't an option because code that this depends on was tested for several days against this specific version. We'd have to go back and test again... To expand on this question, how can I tell which version of MS XML is currently installed?
