  • Add WhereParameters to LinqDataSource in Selecting event

    - by Steven
    I have a repeater using a LinqDataSource as a data source. When a query string is entered, I'd like to filter the results, but ONLY when a query string is entered. If there is no query string, the results should not be filtered, all results should be returned. I'm trying to add a WhereParameter to my LinqDataSource in the Selecting event of the LinqDataSource, but it's not working. Here's my code: protected void ldsImages_Selecting(object sender, LinqDataSourceSelectEventArgs e) { if (Request.QueryString["id"] != null) { e.WhereParameters.Add("ImageTypeID", Request.QueryString["id"]); } }

  • MediaElement.Position behaviour and Windows Phone 7 issue

    - by RoguePlanetoid
    I have a problem, I have written a simple Media Player for Windows Phone 7 and can Play, Stop and control the Volume of a Video (loaded from a URI) however when I try to set the position, this causes the application to freeze. I have used both these lines, but either does not work: Player.Position = new TimeSpan(0, 0, 0, 0, (int)Position.Value); Player.Position = TimeSpan.FromSeconds((int)(Position.Value)); I do have this event handler: void Player_MediaOpened(object sender, RoutedEventArgs e) { Position.Maximum = Player.NaturalDuration.TimeSpan.TotalMilliseconds; } And have tried using the Seconds value, casting to Ints etc, however everytime I try to set the Position, the app freezes. The video otherwise plays normally - anyone know what the problem may be here?

  • Add Trace methods to System.Diagnostics.TraceListner

    - by user200295
    I wrote a Log class derived from System.Diagnostics.TraceListener like so public class Log : TraceListener This acts as a wrapper to Log4Net and allows people to use System.Diagnostics Tracing like so Trace.Listeners.Clear(); Trace.Listeners.Add(new Log("MyProgram")); Trace.TraceInformation("Program Starting"); There is a request to add additional tracing levels then the default Trace ones (Error,Warning,Information) I want to have this added to the System.Diagnostics.Trace so it can be used like Trace.TraceVerbose("blah blah"); Trace.TraceAlert("Alert!"); Is there any way I can do this with an extension class? I tried public static class TraceListenerExtensions { public static void TraceVerbose(this Trace trace) {} } but nothing is being exposed on the trace instance being passed in :(

  • How do I set the jax-ws client request timeout programatically on jboss?

    - by Jonas Andersson
    I am trying to set the request (and connection) timeout for a jax-ws-webservice-client generated with the jaxws-maven-plugin. When running my app under tomcat or jetty the timeout works, but when deployed under jboss it doesn't "take". private void setRequestAndConnectionTimeout(Object wsPort) { String REQUEST_TIMEOUT = BindingProviderProperties.REQUEST_TIMEOUT; // "com.sun.xml.ws.request.timeout"; ((BindingProvider) wsPort).getRequestContext().put(REQUEST_TIMEOUT, timeoutInMillisecs); ((BindingProvider) wsPort).getRequestContext().put(JAXWSProperties.CONNECT_TIMEOUT, timeoutInMillisecs); } What is the correct way to do this for JBoss?

  • Cookies not sent in WebBrowser? (C#, VS2008)

    - by Ivan
    Hi, I'm trying to add cookies to a webbrowser from a cookiecollection. I add them as they should be added but then they are not sent when the request is done. Here is the code I have done hitherto: public void myNav(string url, CookieCollection cc) { foreach (Cookie cook in cc) { webBrowser1.Document.Cookie = cook.ToString(); } this.webBrowser1.Navigate(url); Clipboard.SetText(webBrowser1.Document.Cookie); } If I copy the cookies to the clipboard they are sent correctly, but If I analyse the request with Wireshark they are not sent in the headers. How can I solve this? Thanks in advance, Ivan

  • C++0x and the Lack of Polymorphic Lambdas - Why?

    - by Dominar
    I've been reviewing the draft version of the upcoming C++0x standard. Specifically the section on lambdas, and am confused as to the reasoning for not introducing polymorphic lambdas. I had hoped we could use code such as the following: template<typename Container> void foo(Container c) { for_each(c.begin(),c.end(),[](T& t) { ++t; }); } What were the reasons: Was it the committee ran out of time? That polymorphic lambdas are too hard to implement? Or perhaps that they are seen as not being needed by the PTB?

  • Retrieving "invalid" value from a NumericUpDown Validating event

    - by alhazen
    When the user enters a value above numericUpDown.Maximum, the control's value is automatically set to the maximum. I'd like to display a MessageBox when this occurs, but I'm not able to do that because control.Value and control.Text already contain the automatically set value, maximum, when Validating event is raised. private void numericUpDown_Validating(object sender, System.ComponentModel.CancelEventArgs e) { NumericUpDown control = sender as NumericUpDown; decimal newValue = control.Value; // decimal newValue; // decimal.TryParse(control.Text, out newValue) if (newValue > control.Maximum || newValue < control.Minimum) { // MessageBox } } Thanks

  • release does not free up memory in low-memory condidtion

    - by user322945
    I am trying to follow the Apple's recommendation to handle low-memory warnings (found in Session 416 of WWDC 2009 videos) by freeing up resources used by freeing up my dataController object (referenced in my app delegate) that contains a large number of strings for read from a plist: - (void)applicationDidReceiveMemoryWarning:(UIApplication *)application { [_dataController release]; _dataController = nil; NSLog([NSString stringWithFormat:@"applicationDidReceiveMemoryWarning bottom... retain count:%i", [_dataController retainCount]]); } But when I run ObjectAlloc within Instruments and simulate a Low-Memory Condition, I don't see a decrease in the memory used by my app even though I see the NSLog statements written out and the retain count is zero for the object. I do pass references to the app delegate around to some of the view controllers. But the code above releases the reference to the _dataController object (containing the plist data) so I would expect the memory to be freed. Any help would be appreciated.

  • C# yield return not returning an item as expected

    - by Jiho Han
    I have following code: private void ProcessQueue() { foreach (MessageQueueItem item in GetNextQueuedItem()) PerformAction(item); } private IEnumerable<MessageQueueItem> GetNextQueuedItem() { if (_messageQueue.Count > 0) yield return _messageQueue.Dequeue(); } Initially there is one item in the queue as ProcessQueue is called. During PerformAction, I would add more items to _messageQueue. However, the foreach loop quits after the initial item and does not see the subsequent items added. I sense that somehow the initial state of the queue is being captured by yield. Can someone explain what is happening and give a solution?

  • c# gridview row click

    - by Martijn
    When i click on a row in my gridview, i want to go to a other page with the id i get from the database. In my RowCreated event i have the following line: e.Row.Attributes.Add("onClick", ClientScript.GetPostBackClientHyperlink(this.grdSearchResults, "Select$" + e.Row.RowIndex)); To prevent error messages i have this code: protected override void Render(HtmlTextWriter writer) { // .NET will refuse to accept "unknown" postbacks for security reasons. Because of this we have to register all possible callbacks // This must be done in Render, hence the override for (int i = 0; i < grdSearchResults.Rows.Count; i++) { Page.ClientScript.RegisterForEventValidation(new System.Web.UI.PostBackOptions(grdSearchResults, "Select$" + i.ToString())); } // Do the standard rendering stuff base.Render(writer); } My question is, how can i give a row a unique id (from the DB) and when i click the row, another page is opened (like clicking on a href) and that page can read the id. Thnx

  • Issue with CGEventTapCreate() call.

    - by Dheeraj
    Hi All, I'm trying to register for global key events using this code : void function() { CFMachPortRef keyUpEventTap = CGEventTapCreate(kCGHIDEventTap,kCGHeadInsertEventTap,kCGEventTapOptionListenOnly,CGEventMaskBit(kCGEventKeyUp),&keyUpCallback,NULL); CFRunLoopSourceRef keyUpRunLoopSourceRef = CFMachPortCreateRunLoopSource(NULL, keyUpEventTap, 0); CFRelease(keyUpEventTap); CFRunLoopAddSource(CFRunLoopGetCurrent(), keyUpRunLoopSourceRef, kCFRunLoopDefaultMode); CFRelease(keyUpRunLoopSourceRef); } The application crashes while executing CFMachPortCreateRunLoopSource() call. I think the crash is because of CGEventMaskBit(kCGEventKeyUp) when I create an event tap. But if I create event tap using CGEventTapCreate(kCGHIDEventTap,kCGHeadInsertEventTap,kCGEventTapOptionListenOnly,CGEventMaskBit(kCGEventFlagsChanged),&keyUpCallback,NULL), the application works fine. It does not crash. I'm getting callbacks when any modifier key is pressed. But I need to get callbacks for delete key pressed. Any ideas? Thanks, Dheeraj.

  • iPhone UIScrollView - How to animate scrolling with steady contents?

    - by timbos
    Hi all, I'm wondering if anyone knows how to prevent the contents of a uiscrollview from moving unsteadily when scrolling manually by setting the content offset. When scrolling by touch the text remains clear and steady. I would like to recreate this by animating with the animated option set to false. I'm using a timer to scroll at a given interval. The text is being drawn to a view in the contents, but it vibrates and it becomes more difficult to read clearly when animating at a greater speed. The speed varies and the scrolling must respond to changes in speed quickly. Here's some code - - (void) scrollIncrAmt:(float) amt { _currentSpeedIncr = amt; NSArray* arr = [SharedTickerInfo sharedTickerInfo].sDataArray; DataObj* tdObj = [arr objectAtIndex:_row]; if ( ![tdObj isDirLeft] ) { amt = -amt; } float scrollTo = self.scrollView.contentOffset.x + amt; [scrollView setContentOffset:CGPointMake(scrollTo, 0.0f) animated:NO]; }

    Im getting this exception in the protected virtual void SendPropertyChanged(String propertyName) { if ((this.PropertyChanged != null)) { this.PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); <---- HERE !!! } } of one recently table association i created, there lots of same associations around the database, and this happened in the 4 specific tables i added. Its 1...* relationship and association is Primary Table - Id (identity auto generated) Foreign PId column int not null. I just dont get it....Im using SqlMetal for generation, i regenerated the schema, rebuild, same. This is causing while inserting row in DevExpress XtraGrid, but i dont think this should be issue, same control with same functionality but for different tables works ok. I use grid's event for append value in a property when the entity creating. I disabled this but same again. Recreated the association. No change, exception occurs. Any ideas?

  • Does JSONP scale? How many JSONP requests can I send?

    - by Cheeso
    Based on Please explain JSONP, I understand that JSONP can be used to get around the same-origin policy. But in order to do that, the page must use a <script> tag. I know that pages can dynamically emit new script tags, such as with: <script type="text/javascript" language='javascript'> document.write('<script type="text/javascript" ' + 'id="contentloadtag" defer="defer" ' + 'src="javascript:void(0)"><\/script>'); var contentloadtag=document.getElementById("contentloadtag"); contentloadtag.onreadystatechange=function(){ if (this.readyState=="complete") { init(); } } </script> (the above works in IE, don't think it works in FF). ... but does this mean, effectively, that every JSONP call requires me to emit another <script> tag into the document? Can I remove the <script> tags that are done?
