  • How to append new elements to Xml from a stream

    - by Wololo
    I have a method which returns some xml in a memory stream private MemoryStream GetXml() { XmlWriterSettings settings = new XmlWriterSettings(); settings.Indent = true; using (MemoryStream memoryStream = new MemoryStream()) { using (XmlWriter writer = XmlWriter.Create(memoryStream, settings)) { writer.WriteStartDocument(); writer.WriteStartElement("root"); writer.WriteStartElement("element"); writer.WriteString("content"); writer.WriteEndElement(); writer.WriteEndElement(); writer.WriteEndDocument(); writer.Flush(); } return memoryStream; } } In this example the format of the xml will be: <?xml version="1.0" encoding="utf-8"?> <root> <element>content</element> </root> How can i insert a new element under the root e.g <?xml version="1.0" encoding="utf-8"?> <root> <element>content</element> ----->New element here <------ </root> EDIT: Also please suggest the most efficient method as returning a memorystream may not be the best solution. The final xml will be passed to a custom HttpHandler so what are the best options for writing the output? context.Response.Write vs context.Response.OutputStream

  • SWT: problems with clicking button after using setEnabled() on Linux

    - by Laimoncijus
    Hi, I have a strange case with SWT and Button after using setEnabled() - seems if I disable and enable button at least once - I cannot properly click with mouse on it anymore... Already minify code to very basic: import org.eclipse.swt.SWT; import org.eclipse.swt.events.SelectionEvent; import org.eclipse.swt.events.SelectionListener; import org.eclipse.swt.layout.GridLayout; import org.eclipse.swt.widgets.Button; import org.eclipse.swt.widgets.Display; import org.eclipse.swt.widgets.Shell; public class TestButton { public TestButton() { Display display = new Display(); Shell shell = new Shell(display); GridLayout mainLayout = new GridLayout(); shell.setLayout(mainLayout); shell.setSize(100, 100); Button testButton = new Button(shell, SWT.PUSH); testButton.addSelectionListener(new TestClickListener()); testButton.setText("Click me!"); //testButton.setEnabled(false); //testButton.setEnabled(true); shell.open(); while (!shell.isDisposed()) { if (!display.readAndDispatch()) display.sleep(); } display.dispose(); } class TestClickListener implements SelectionListener { @Override public void widgetDefaultSelected(SelectionEvent e) { } @Override public void widgetSelected(SelectionEvent e) { System.out.println("Click!"); } } public static void main(String[] args) { new TestButton(); } } When I keep these 2 lines commented out - I can properly click on a button and always get "Click!" logged, but if I uncomment them - then I can't click on button properly with mouse anymore - button visually seems to be clicked, but nothing is logged... Am I doing something wrong here? Or maybe it's some kind of bug on Linux platform? Because on Mac running the same code I never experienced such problems... Thanks for any hint! P.S. Running code on Ubuntu 9.10, Gnome + Compiz, Sun Java 1.6.0.16

  • Get Mechanize to handle cookies from an arbitrary POST (to log into https://www.t-mobile.com/ progra

    - by Horace Loeb
    I want to log into https://www.t-mobile.com/ programmatically. My first idea was to use Mechanize to submit the login form: However, it turns out that this isn't even a real form. Instead, when you click "Log in" some javascript grabs the values of the fields, creates a new form dynamically, and submits it. "Log in" button HTML: <button onclick="handleLogin(); return false;" class="btnBlue" id="myTMobile-login"><span>Log in</span></button> The handleLogin() function: function handleLogin() { if (ValidateMsisdnPassword()) { // client-side form validation logic var a = document.createElement("FORM"); a.name = "form1"; a.method = "POST"; a.action = mytmoUrl; // defined elsewhere as https://my.t-mobile.com/Login/LoginController.aspx var c = document.createElement("INPUT"); c.type = "HIDDEN"; c.value = document.getElementById("myTMobile-phone").value; // the value of the phone number input field c.name = "txtMSISDN"; a.appendChild(c); var b = document.createElement("INPUT"); b.type = "HIDDEN"; b.value = document.getElementById("myTMobile-password").value; // the value of the password input field b.name = "txtPassword"; a.appendChild(b); document.body.appendChild(a); a.submit(); return true } else { return false } } I could simulate this form submission by POSTing the form data to https://my.t-mobile.com/Login/LoginController.aspx with Net::HTTP#post_form, but I don't know how to get the resultant cookie into Mechanize so I can continue to scrape the UI available when I'm logged in. Any ideas?

  • HP QTP 10: Web-app testing - SomeObj.FireEvent("OnCLick") works, SomeObj.Object.FireEvent("OnCLick") doesn't

    - by Vitaliy
    Hi all! I have rich web app btuil with ExtJS. It has multi-select list control (created with JS+CSS). I want to click on some item in that list using HP QuickTest Pro 10 with Internet Explorer 6. I added that item into Object repository and found that following code works - selects some item: Browser("blah").Page("blah").WebElement("SomeElem").Click next code also works: Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseDown") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onMouseUp") Browser("blah").Page("blah").WebElement("SomeElem").FireEvent("onClick") But I want to select several items using shift+click method. I don't know to do that :( So I have a few questions: How can perform click with mouse on several web elements with Shift key pressed? I tried to do that using CreateEventObject + shiftKey set to true, but the method (perform fireEvent on DOM object, not object from Object repository) doesn't work: Browser("blah").Page("blah").WebElement("SomeElem").Object.FireEvent("onClick") What the difference between WebElement("Element").FireEvent("OnClick") and WebElement("Element").Object.FireEvent("OnClick") ? Plsease, help someone, because I fought with that problem a lot, but had no result. Thanks!

  • php - disconnecting and connecting to multiple databases

    - by Phil Jackson
    Hi, I want to be able to switch from the current db to multiple dbs though a loop: $query = mysql_query("SELECT * FROM `linkedin` ORDER BY id", $CON ) or die( mysql_error() ); if( mysql_num_rows( $query ) != 0 ) { $last_update = time() / 60; while( $rows = mysql_fetch_array( $query ) ) { $contacts_db = "NNJN_" . $rows['email']; // switch to the contacts db mysql_select_db( $contacts_db, $CON ); $query = mysql_query("SELECT * FROM `linkedin` WHERE token = '" . TOKEN . "'", $CON ) or die( mysql_error() ); if( mysql_num_rows( $query ) != 0 ) { mysql_query("UPDATE `linkedin` SET last_update = '{$last_update}' WHERE token = '" . TOKEN .

"', 'true', 'false', '$last_update')", $CON ) or die( mysql_error() ); } } mysql_free_result( $query ); } // switch back to your own mysql_select_db( USER_DB, $CON ); It does insert and update details from the other databases but it also inserts and edits data from the current users database which I dont want. Any ideas?

  • What algorithms are suitable for this simple machine learning problem?

    - by user213060
    I have a what I think is a simple machine learning question. Here is the basic problem: I am repeatedly given a new object and a list of descriptions about the object. For example: new_object: 'bob' new_object_descriptions: ['tall','old','funny']. I then have to use some kind of machine learning to find previously handled objects that had similar descriptions, for example, past_similar_objects: ['frank','steve','joe']. Next, I have an algorithm that can directly measure whether these objects are indeed similar to bob, for example, correct_objects: ['steve','joe']. The classifier is then given this feedback training of successful matches. Then this loop repeats with a new object. a Here's the pseudo-code: Classifier=new_classifier() while True: new_object,new_object_descriptions = get_new_object_and_descriptions() past_similar_objects = Classifier.classify(new_object,new_object_descriptions) correct_objects = calc_successful_matches(new_object,past_similar_objects) Classifier.train_successful_matches(object,correct_objects) But, there are some stipulations that may limit what classifier can be used: There will be millions of objects put into this classifier so classification and training needs to scale well to millions of object types and still be fast. I believe this disqualifies something like a spam classifier that is optimal for just two types: spam or not spam. (Update: I could probably narrow this to thousands of objects instead of millions, if that is a problem.) Again, I prefer speed when millions of objects are being classified, over accuracy. What are decent, fast machine learning algorithms for this purpose?

  • JPA - Setting entity class property from calculated column?

    - by growse
    I'm just getting to grips with JPA in a simple Java web app running on Glassfish 3 (Persistence provider is EclipseLink). So far, I'm really liking it (bugs in netbeans/glassfish interaction aside) but there's a thing that I want to be able to do that I'm not sure how to do. I've got an entity class (Article) that's mapped to a database table (article). I'm trying to do a query on the database that returns a calculated column, but I can't figure out how to set up a property of the Article class so that the property gets filled by the column value when I call the query. If I do a regular "select id,title,body from article" query, I get a list of Article objects fine, with the id, title and body properties filled. This works fine. However, if I do the below: Query q = em.createNativeQuery("select id,title,shorttitle,datestamp,body,true as published, ts_headline(body,q,'ShortWord=0') as headline, type from articles,to_tsquery('english',?) as q where idxfti @@ q order by ts_rank(idxfti,q) desc",Article.class); (this is a fulltext search using tsearch2 on Postgres - it's a db-specific function, so I'm using a NativeQuery) You can see I'm fetching a calculated column, called headline. How do I add a headline property to my Article class so that it gets populated by this query? So far, I've tried setting it to be @Transient, but that just ends up with it being null all the time.

  • How to access generic property without knowing the closed generic type

    - by Martin Booka Weser
    I have a generic Type as follows public class TestGeneric<T> { public T Data { get; set; } public TestGeneric(T data) { this.Data = data; } } If i have now an object (which is coming from some external source) from which i know that it's type is of some closed TestGeneric<, but i don't know the TypeParameter T. Now I need to access the Data of my object. Problem is that i can't cast the object, since i don't know exactly to which closed TestGeneric. I use // thx to http://stackoverflow.com/questions/457676/c-reflection-check-if-a-class-is-derived-from-a-generic-class private static bool IsSubclassOfRawGeneric(Type rawGeneric, Type subclass) { while (subclass != typeof(object)) { var cur = subclass.IsGenericType ? subclass.GetGenericTypeDefinition() : subclass; if (rawGeneric == cur) { return true; } subclass = subclass.BaseType; } return false; } to make sure, my object is of the generic type. The code in question is as follows: public static void Main() { object myObject = new TestGeneric<string>("test"); // or from another source if (IsSubclassOfRawGeneric(typeof(TestGeneric<>), myObject.GetType())) { // the following gives an InvalidCastException // var data = ((TestGeneric<object>)myObject).Data; // if i try to access the property with reflection // i get an InvalidOperationException var dataProperty = typeof(TestGeneric<>).GetProperty("Data"); object data = dataProperty.GetValue(myObject, new object[] { }); } } I need the Data regardless of its type (well, if i could ask for its type using GetType() would be fine, but not necessary) since i just want to dump it in xml using ToString(). Any suggestions? Thanx.

  • Problem with DataTrigger binding - setters are not being called

    - by aoven
    I have a Command bound to a Button in XAML. When executed, the command changes a property value on the underlying DataContext. I would like the button's Content to reflect the new value of the property. This works*: <Button Command="{x:Static Member=local:MyCommands.TestCommand}" Content="{Binding Path=TestProperty, Mode=OneWay}" /> But this doesn't: <Button Command="{x:Static Member=local:MyCommands.TestCommand}"> <Button.Style> <Style TargetType="{x:Type Button}"> <Style.Triggers> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="True"> <DataTrigger.Setters> <Setter Property="Content" Value="Yes"/> </DataTrigger.Setters> </DataTrigger> <DataTrigger Binding="{Binding Path=TestProperty, Mode=OneWay}" Value="False"> <DataTrigger.Setters> <Setter Property="Content" Value="No"/> </DataTrigger.Setters> </DataTrigger> </Style.Triggers> </Style> </Button.Style> </Button> Why is that? * By "works" I mean the Content gets updated whenever I click the button. TIA

  • Thread implemented as a Singleton

    - by rocknroll
    Hi all, I have a commercial application made with C,C++/Qt on Linux platform. The app collects data from different sensors and displays them on GUI. Each of the protocol for interfacing with sensors is implemented using singleton pattern and threads from Qt QThreads class. All the protocols except one work fine. Each protocol's run function for thread has following structure: void <ProtocolClassName>::run() { while(!mStop) //check whether screen is closed or not { mutex.lock() while(!waitcondition.wait(&mutex,5)) { if(mStop) return; } //Code for receiving and processing incoming data mutex.unlock(); } //end while } Hierarchy of GUI. 1.Login screen. 2. Screen of action. When a user logs in from login screen, we enter the action screen where all data is displayed and all the thread's for different sensors start. They wait on mStop variable in idle time and when data arrives they jump to receiving and processing data. Incoming data for the problem protocol is 117 bytes. In the main GUI threads there are timers which when timeout, grab the running instance of protocol using <ProtocolName>::instance() function Check the update variable of singleton class if its true and display the data. When the data display is done they reset the update variable in singleton class to false. The problematic protocol has the update time of 1 sec, which is also the frame rate of protocol. When I comment out the display function it runs fine. But when display is activated the application hangs consistently after 6-7 hours. I have asked this question on many forums but haven't received any worthwhile suggestions. I Hope that here I will get some help. Also, I have read a lot of literature on Singleton, multithreading, and found that people always discourage the use of singletons especially in C++. But in my application I can think of no other design for implementation. Thanks in advance A Hapless programmer

  • Excel Automation From .NET - creating a new worksheet

    - by Andrew Shepherd
    I am attempting what seems like a simple task: using C# to create a new Excel document containing new worksheets. For some reason, I am getting a strange COM error (0x800A03EC) Has anyone managed to get this to work? Does anyone have suggestions as to how to troubleshoot this? I've isolated this into the minimum amount of code: using Microsoft.Office.Interop.Excel; using System.Diagnostics; namespace ExcelAutomation { public static class ExcelTests { public static void CreateWorksheet() { try { var app = new Microsoft.Office.Interop.Excel.Application(); app.Visible = true; var workBooks = app.Workbooks; var newWorkbook = app.Workbooks.Add(XlWBATemplate.xlWBATWorksheet); Worksheet existingWorksheet = (Worksheet)newWorkbook.Sheets[1]; Worksheet workSheet = (Worksheet)newWorkbook.Sheets.Add ( null, // before existingWorksheet, null, // 1, null //XlSheetType.xlWorksheet ); } catch (System.Runtime.InteropServices.COMException ex) { Trace.WriteLine(string.Format("Caught COMException. Message: \"{0}\"", ex.Message)); } } } } The output window now says: Caught COMException. Message: "Exception from HRESULT: 0x800A03EC"

  • even PHP has 'bugs' with IE

    - by silversky
    It's not a real bug BUT for sure it is not what you would expect. I have this sample code to upload images: <?php if($type=="image/jpg" || $type=="image/jpeg" || $type=="image/pjpeg" || $type=="image/tiff" || $type=="image/gif" || $type=="image/png") { // make upload else echo "Incorect format ...."; ?> The problem is that that if I modify the extention of an image, let's say to .jpgq or even .jpg% and i try to upload it FF and Chrome will say that the file"s type is "application/octet-stream" and normaly the condition will be false BUT since IE is 'smarter' that other brow. it will say that the file is "image/pjeg and the condition will be true and the file will be uploaded and of course latter any brow. will not be able to read / view the image. It is not a bug because on msdn.microsoft.com it says that: "If the "suggested" (server-provided) MIME type is unknown (not known and not ambiguous), FindMimeFromData immediately returns this MIME type" and "If the server-provided MIME type is either known or ambiguous, the buffer is scanned in an attempt to verify or obtain a MIME type from the actual content." plus others 'inovative solutions from Microsoft'. SO my questions are: Why is IE so 'smart' and when I upload the file to server it knows the real MIME type BUT it will fail to read it from the server ? How can i work around this issue (if the file doesn't have the right extention the condition has to be false)? Is it wise to check the extention format (and not the MIME type)? is any of the above extention not recomended to use ? Should I add others?

  • Running another process without GUI freezing

  • GAE - Getting TypeError requiring class instance be passed to class's own method...

    I'm really new to programming... I set up a class to give supporting information for Google's User API user object. I store this info in the datastore using db.model. When I call the okstatus method of my user_info class using this code: elif user_info.okstatus(user): self.response.out.write("user allowed") I get this error: unbound method okstatus() must be called with user_info instance as first argument (got User instance instead) Here is my user_info class. class user_info: def auth_ctrlr(self, user): if self.status(user) == status_allowed: return ("<a href=\"%s\">Sign Out</a>)" % (users.create_login_url("/"))) else: return ("<a href=\"%s\">Sign In or Get an Account</a>)" % (users.create_logout_url("/"))) def status(self, user): match = sub_user.gql(qu_by_user_id, user.user_id) return match.string_status def group(self, user): match = sub_user.gql(qu_by_user_id, user.user_id) grp = group_names.gql(qu_by_user_id, match.groupID) return grp def okstatus(self, user): match = self.status(user) if match == status_allowed: return True My understanding is that the argument "self" inside the method's calling arguments describes it as a child to the class. I've tried everything I can think of and can't find any related info online. Can someone please tell me what I'm doing wrong? Thanks

  • Generating code -- is there an easy way to get a proper string representation of nullable type?

    - by Cory Larson
    So I'm building an application that is going to do a ton of code generation with both C# and VB output (depending on project settings). I've got a CodeTemplateEngine, with two derived classes VBTemplateEngine and CSharpTemplateEngine. This question regards creating the property signatures based on columns in a database table. Using the IDataReader's GetSchemaTable method I gather the CLR type of the column, such as "System.Int32", and whether it IsNullable. However, I'd like to keep the code simple, and instead of having a property that looks like: public System.Int32? SomeIntegerColumn { get; set; } or public Nullable<System.Int32> SomeIntegerColumn { get; set; }, where the property type would be resolved with this function (from my VBTemplateEngine), public override string ResolveCLRType(bool? isNullable, string runtimeType) { Type type = TypeUtils.ResolveType(runtimeType); if (isNullable.HasValue && isNullable.Value == true && type.IsValueType) { return "System.Nullable(Of " + type.FullName + ")"; // or, for example... return type.FullName + "?"; } else { return type.FullName; } }, I would like to generate a simpler property. I hate the idea of building a Type string from nothing, and I would rather have something like: public int? SomeIntegerColumn { get; set; } Is there anything built-in anywhere, such as in the VBCodeProvider or CSharpCodeProvider classes that would somehow take care of this for me? Or is there a way to get a type alias of int? from a type string like System.Nullable'1[System.Int32]? Thanks!

  • Conditions with common logic: question of style, readability, efficiency, ...

    - by cdonner
    I have conditional logic that requires pre-processing that is common to each of the conditions (instantiating objects, database lookups etc). I can think of 3 possible ways to do this, but each has a flaw: Option 1 if A prepare processing do A logic else if B prepare processing do B logic else if C prepare processing do C logic // else do nothing end The flaw with option 1 is that the expensive code is redundant. Option 2 prepare processing // not necessary unless A, B, or C if A do A logic else if B do B logic else if C do C logic // else do nothing end The flaw with option 2 is that the expensive code runs even when neither A, B or C is true Option 3 if (A, B, or C) prepare processing end if A do A logic else if B do B logic else if C do C logic end The flaw with option 3 is that the conditions for A, B, C are being evaluated twice. The evaluation is also costly. Now that I think about it, there is a variant of option 3 that I call option 4: Option 4 if (A, B, or C) prepare processing if A set D else if B set E else if C set F end end if D do A logic else if E do B logic else if F do C logic end While this does address the costly evaluations of A, B, and C, it makes the whole thing more ugly and I don't like it. How would you rank the options, and are there any others that I am not seeing?

  • How can I run a local Windows Application and have the output be piped into the Browser.

    - by Trey Sherrill
    I have Windows Application (.EXE file is written in C and built with MS-Visual Studio), that outputs ASCII text to stdout. I’m looking to enhance the ASCII text to include limited HTML with a few links. I’d like to invoke this application (.EXE File) and take the output of that application and pipe it into a Browser. This is not a one time thing, each new web page would be another run of the Local Application! The HTML/java-script application below has worked for me to execute the application, but the output has gone into a DOS Box windows and not to pipe it into the Browser. I’d like to update this HTML Application to enable the Browser to capture that text (that is enhanced with HTML) and display it with the browser. <body> <script> function go() { w = new ActiveXObject("WScript.Shell"); w.run('C:/DL/Browser/mk_html.exe'); return true; } </script> <form> Run My Application (Window with explorer only) <input type="button" value="Go" onClick="return go()"> </FORM> </body>

  • Java: Cleaning up what causes a connection reset

    - by Zombies
    There seems to be some confusion as well contradicting statements on various SO answers: http://stackoverflow.com/questions/585599/whats-causing-my-java-net-socketexception-connection-reset . You can see here that the accepted answer states that the connection was closed by other side. But this is not true, closing a connection doesn't cause a connection reset. It is cauesed by "an underlying TCP/IP error." What I want to know is if a SocketException: Connection reset means really besides "unerlying TCP/IP Error." What really causes this? As I doubt it has anything to do with the connection being closed (since closing a connection isn't an exception worthy flag, and reading from a closed connection is, but that isn't an "underlying TCP/IP error." My hypothesis is this Connection reset is caused from a server's failure to acknowledge an ACK packet (either wholly or just improperly as per TCP/IP). And that a SocketTimeoutException is generated only when no data is generated to be read (since this is thrown during a read after a certain duration, and read is waiting for data, but is not concerned with ACK packets). In other words, read() throws SocketTimeoutException if it didn't read any bytes of actual data (DATA LAYER) in its allotted time.

  • Custom model validation of dependent properties using Data Annotations

    - by Darin Dimitrov
    Since now I've used the excellent FluentValidation library to validate my model classes. In web applications I use it in conjunction with the jquery.validate plugin to perform client side validation as well. One drawback is that much of the validation logic is repeated on the client side and is no longer centralized at a single place. For this reason I'm looking for an alternative. There are many examples out there showing the usage of data annotations to perform model validation. It looks very promising. One thing I couldn't find out is how to validate a property that depends on another property value. Let's take for example the following model: public class Event { [Required] public DateTime? StartDate { get; set; } [Required] public DateTime? EndDate { get; set; } } I would like to ensure that EndDate is greater than StartDate. I could write a custom validation attribute extending ValidationAttribute in order to perform custom validation logic. Unfortunately I couldn't find a way to obtain the model instance: public class CustomValidationAttribute : ValidationAttribute { public override bool IsValid(object value) { // value represents the property value on which this attribute is applied // but how to obtain the object instance to which this property belongs? return true; } } I found that the CustomValidationAttribute seems to do the job because it has this ValidationContext property that contains the object instance being validated. Unfortunately this attribute has been added only in .NET 4.0. So my question is: can I achieve the same functionality in .NET 3.5 SP1? UPDATE: It seems that FluentValidation already supports clientside validation and metadata in ASP.NET MVC 2. Still it would be good to know though if data annotations could be used to validate dependent properties.

  • PHP header redirection does nor reload <iframe> in IE

    - by Marco Demaio
    When displaying data from DB usually I'm in this situation I'm in page A.php that shows data from DB, user performs some action (like edit/delete etc) and page B.php is loaded to perform the action, once page B performed the action, it redirects browser to page A, page A is auto reloaded during step (3) therefor it shows an updated situation of the data In order to make page B to redirect to page A i use a simple PHP header("Location: " . "A.php", TRUE, 302); This works well in all situations, except when pages A.php is displaied into an <iframe>: in such a case it does not reload (step 4 does not get done). This seems to happen only in IE7 (don't know about IE8), it works perfectly on FF/Safari. And only when using an <iframe>, if page A.php is not in <iframe> it gest refreshed also in IE7. In order to solve this I simply added a couple of headers in page A.php to set it to not be cached: header("Cache-Control: no-cache, must-revalidate"); // HTTP/1.1 header("Expires: Sat, 26 Jul 1997 05:00:00 GMT"); // Date in the past But I was curious if you migt have exeperienced the same issue too in the past, and if you good give me some advises about this. Thanks!

  • ASP.net download page

    - by Russel
    Hi I have a Reports.aspx ASP.NET page that allows users to download excel report files by clicking on several hyperlinks. When a report hyperlink is clicked, I open a new window using the javascript window.open method and navigate off to the download.aspx page. The code-behind for the download page creates a excel file on the fly using openxml(in memory) and send it back to the browser. Here is some code from the download.aspx page: byte[] outputFileBytes = CreateExcelReport().ToArray(); Response.Clear(); Response.BufferOutput = true; Response.ContentType = "application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"; Response.AddHeader("Content-Disposition", string.Format("attachment; filename={0}", "tempReport.xlsx")); Response.BinaryWrite(outputFileBytes); Response.Flush(); Response.Close(); Response.End(); My problem : Some of these reports take some time to generate. I would like to display a loading.gif file on my Reports.aspx page, while the download.aspx page is requested. Once the page request is completed, the loading.gif file should be made invisible. Is there a way to achieve this. Perhaps some kind of event. I have mootools to my disposal. Thanks PS. I know that generating reports like this is not ideal, but thats a different story all together...
