  • Issue with dynamic array Queue data structure with void pointer

    - by Nazgulled
    Hi, Maybe there's no way to solve this the way I'd like it but I don't know everything so I better ask... I've implemented a simple Queue with a dynamic array so the user can initialize with whatever number of items it wants. I'm also trying to use a void pointer as to allow any data type, but that's the problem. Here's my code: typedef void * QueueValue; typedef struct sQueueItem { QueueValue value; } QueueItem; typedef struct sQueue { QueueItem *items; int first; int last; int size; int count; } Queue; void queueInitialize(Queue **queue, size_t size) { *queue = xmalloc(sizeof(Queue)); QueueItem *items = xmalloc(sizeof(QueueItem) * size); (*queue)->items = items; (*queue)->first = 0; (*queue)->last = 0; (*queue)->size = size; (*queue)->count = 0; } Bool queuePush(Queue * const queue, QueueValue value, size_t val_sz) { if(isNull(queue) || isFull(queue)) return FALSE; queue->items[queue->last].value = xmalloc(val_sz); memcpy(queue->items[queue->last].value, value, val_sz); queue->last = (queue->last+1) % queue->size; queue->count += 1; return TRUE; } Bool queuePop(Queue * const queue, QueueValue *value) { if(isEmpty(queue)) return FALSE; *value = queue->items[queue->first].value; free(queue->items[queue->first].value); queue->first = (queue->first+1) % queue->size; queue->count -= 1; return TRUE; } The problem lies on the queuePop function. When I call it, I lose the value because I free it right away. I can't seem to solve this dilemma. I want my library to be generic and modular. The user should not care about allocating and freeing memory, that's the library's job. How can the user still get the value from queuePop and let the library handle all memory allocs/frees?

  • Bugs in Excel's ActiveX combo boxes?

    - by k.robinson
    I have noticed that I get all sorts of annoying errors when: I have ActiveX comboboxes on a worksheet (not an excel form) The comboboxes have event code linked to them (eg, onchange events) I use their listfillrange or linkedcell properties (clearing these properties seems to alleviate a lot of problems) (Not sure if this is connected) but there is data validation on the targeted linkedcell. I program a fairly complex excel application that does a ton of event handling and uses a lot of controls. Over the months, I have been trying to deal with a variety of bugs dealing with those combo boxes. I can't recall all the details of each instance now, but these bugs tend to involve pointing the listfillrange and linkedcell properties at named ranges, and often have to do with the combo box events triggering at inappropriate times (such as when application.enableevents = false). These problems seemed to grow bigger in Excel 2007, so that I had to give up on these combo boxes entirely (I now use combo boxes contained in user forms, rather than directly on the sheets). Has anyone else seen similar problems? If so, was there a graceful solution? I have looked around with Google and so far haven't spotted anyone with similar issues. Some of the symptoms I end up seeing are: Excel crashing when I start up (involves combobox_onchange, listfillrange-named range on another different sheet, and workbook_open interactions). (note, I also had some data validation on the the linked cells in case a user edited them directly.) Excel rendering bugs (usually when the combo box changes, some cells from another sheet get randomly drawn over the top of the current sheet) Sometimes it involves the screen flashing entirely to another sheet for a moment. Excel losing its mind (or rather, the call stack) (related to the first bullet point). Sometimes when a function modifies a property of the comboboxes, the combobox onchange event fires, but it never returns control to the function that caused the change in the first place. The combobox_onchange events are triggered even when application.enableevents = false. Events firing when they shouldn't (I posted another question on stack overflow related to this). At this point, I am fairly convinced that ActiveX comboboxes are evil incarnate and not worth the trouble. I have switched to including these comboboxes inside a userform module instead. I would rather inconvenience users with popup forms than random visual artifacts and crashing (with data loss).

  • Where to stop/destroy threads in Android Service class?

    - by niko
    Hi, I have created a threaded service the following way: public class TCPClientService extends Service{ ... @Override public void onCreate() { ... Measurements = new LinkedList<String>(); enableDataSending(); } @Override public IBinder onBind(Intent intent) { //TODO: Replace with service binding implementation return null; } @Override public void onLowMemory() { Measurements.clear(); super.onLowMemory(); }; @Override public void onDestroy() { Measurements.clear(); super.onDestroy(); try { SendDataThread.stop(); } catch(Exception e) { } }; private Runnable backgrounSendData = new Runnable() { public void run() { doSendData(); } }; private void enableDataSending() { SendDataThread = new Thread(null, backgrounSendData, "send_data"); SendDataThread.start(); } private void addMeasurementToQueue() { if(Measurements.size() <= 100) { String measurement = packData(); Measurements.add(measurement); } } private void doSendData() { while(true) { try { if(Measurements.isEmpty()) { Thread.sleep(1000); continue; } //Log.d("TCP", "C: Connecting..."); Socket socket = new Socket(); socket.setTcpNoDelay(true); socket.connect(new InetSocketAddress(serverAddress, portNumber), 3000); //socket.connect(new InetSocketAddress(serverAddress, portNumber)); if(!socket.isConnected()) { throw new Exception("Server Unavailable!"); } try { //Log.d("TCP", "C: Sending: '" + message + "'"); PrintWriter out = new PrintWriter( new BufferedWriter( new OutputStreamWriter(socket.getOutputStream())),true); String message = Measurements.remove(); out.println(message); Thread.sleep(200); Log.d("TCP", "C: Sent."); Log.d("TCP", "C: Done."); connectionAvailable = true; } catch(Exception e) { Log.e("TCP", "S: Error", e); connectionAvailable = false; } finally { socket.close(); announceNetworkAvailability(connectionAvailable); } } catch (Exception e) { Log.e("TCP", "C: Error", e); connectionAvailable = false; announceNetworkAvailability(connectionAvailable); } } } } After I close the application the phone works really slow and I guess it is due to thread termination failure. Does anyone know what is the best way to terminate all threads before terminating the application?

  • ZPL II Extended Characters

    - by Mauro
    I'm trying to print extended code page 850 characters using ZPL II to a Zebra S4M. Whenever one of the extended characters I.E. ASCII value 127 is used I get a box of varying shades of grey instead of the actual value. I'm trying to print ± and ° (ALT+0177 and ALT+0176). I suspect its the RawPrinterHelper I am trying to use (as downloaded from MS, and another from CodeProject) however I cant see where the character codes are going wrong. Weirdly, printing direct from Notepad renders the correct characters, which leads me to believe it is a problem with the raw printer helper class. I am not tied to using the Raw Printer Helper class so if there is a better way of doing it, I am more than happy to see them. SAMPLE ZPLII Without escaped chars ^XA ^FO30,200^AD^FH,18,10^FD35 ± 2 ° ^FS ^FS ^XZ With escaped chars (tried both upper and lower case) ^XA ^FO30,200^AD^FH,18,10^FD35 _b0 2 _b1 ^FS ^FS ^XZ Raw Printer Helper [StructLayout(LayoutKind.Sequential)] public struct DOCINFO { [MarshalAs(UnmanagedType.LPWStr)] public string printerDocumentName; [MarshalAs(UnmanagedType.LPWStr)] public string pOutputFile; [MarshalAs(UnmanagedType.LPWStr)] public string printerDocumentDataType; } public class RawPrinter { [ DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = false, CallingConvention = CallingConvention.StdCall)] public static extern long OpenPrinter(string pPrinterName, ref IntPtr phPrinter, int pDefault); [ DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = false, CallingConvention = CallingConvention.StdCall)] public static extern long StartDocPrinter(IntPtr hPrinter, int Level, ref DOCINFO pDocInfo); [ DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] public static extern long StartPagePrinter(IntPtr hPrinter); [ DllImport("winspool.drv", CharSet = CharSet.Ansi, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] public static extern long WritePrinter(IntPtr hPrinter, string data, int buf, ref int pcWritten); [ DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] public static extern long EndPagePrinter(IntPtr hPrinter); [ DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] public static extern long EndDocPrinter(IntPtr hPrinter); [ DllImport("winspool.drv", CharSet = CharSet.Unicode, ExactSpelling = true, CallingConvention = CallingConvention.StdCall)] public static extern long ClosePrinter(IntPtr hPrinter); public static void SendToPrinter(string printerJobName, string rawStringToSendToThePrinter, string printerNameAsDescribedByPrintManager) { IntPtr handleForTheOpenPrinter = new IntPtr(); DOCINFO documentInformation = new DOCINFO(); int printerBytesWritten = 0; documentInformation.printerDocumentName = printerJobName; documentInformation.printerDocumentDataType = "RAW"; OpenPrinter(printerNameAsDescribedByPrintManager, ref handleForTheOpenPrinter, 0); StartDocPrinter(handleForTheOpenPrinter, 1, ref documentInformation); StartPagePrinter(handleForTheOpenPrinter); WritePrinter(handleForTheOpenPrinter, rawStringToSendToThePrinter, rawStringToSendToThePrinter.Length, ref printerBytesWritten); EndPagePrinter(handleForTheOpenPrinter); EndDocPrinter(handleForTheOpenPrinter); ClosePrinter(handleForTheOpenPrinter); } }

  • JQuery dialog momentairly displayed on page load

    - by Kevin Won
    I created a page that has a JQuery based dialog using the standard JQuery UI function. I do this with out of the box functionality of JQuery... nothing special at all. Here is my HTML for the dialog: <div id = "myDialog"> <!-- ... more html in here for the dialog --> </div> Then the JQuery called in javascript that transforms the <div> to a dialog: // pruned .js as an example of kicking up a JQuery dialog $('#myDialog').dialog({ autoOpen: false, title: 'Title here', modal: true } }); Again, plain-vanilla JQuery. So you start this wizard by clicking on a link on the parent page, and it then spawns a JQuery dialog which has a significant chunk of HTML that includes images, etc. As I continued developing this page, I started to notice that when I loaded the page in the browser that the <div> tags I was putting in that JQuery transforms into dialogs would very briefly be displayed. Then the page would act as expected. In other words, the dialog would not be hidden, it would be displayed briefly in-line in the page. Quite ugly and unprofessional looking! But after a split second, the page would render correctly and look just as I expected/wanted. Over time, as the page size grew, the time the page would remain incorrectly rendered grew. My guess is that the rendering engine of the browser is rendering the page as it is loading, then at the end it is kicking off the JQuery that will transform the <div> into a dialog. This JQuery function will then transform the simple <div> to a JQuery dialog and hide it (since I have the autoOpen property set to false). Some browsers <cough>IE</cough> display it longer than others. My large-ish dialog now causes the page to incorrectly render for about 1 second... YUCK! I came up with a resolution to this problem which works OK, but I'm wondering if someone knows of a better way.

  • Silverlight 4 + WCF RIA - Data Service Design Best Practices

    - by Chadd Nervig
    Hey all. I realize this is a rather long question, but I'd really appreciate any help from anyone experienced with RIA services. Thanks! I'm working on a Silverlight 4 app that views data from the server. I'm relatively inexperienced with RIA Services, so have been working through the tasks of getting the data I need down to the client, but every new piece I add to the puzzle seems to be more and more problematic. I feel like I'm missing some basic concepts here, and it seems like I'm just 'hacking' pieces on, in time-consuming ways, each one breaking the previous ones as I try to add them. I'd love to get the feedback of developers experienced with RIA services, to figure out the intended way to do what I'm trying to do. Let me lay out what I'm trying to do: First, the data. The source of this data is a variety of sources, primarily created by a shared library which reads data from our database, and exposes it as POCOs (Plain Old CLR Objects). I'm creating my own POCOs to represent the different types of data I need to pass between server and client. DataA - This app is for viewing a certain type of data, lets call DataA, in near-realtime. Every 3 minutes, the client should pull data down from the server, of all the new DataA since the last time it requested data. DataB - Users can view the DataA objects in the app, and may select one of them from the list, which displays additional details about that DataA. I'm bringing these extra details down from the server as DataB. DataC - One of the things that DataB contains is a history of a couple important values over time. I'm calling each data point of this history a DataC object, and each DataB object contains many DataCs. The Data Model - On the server side, I have a single DomainService: [EnableClientAccess] public class MyDomainService : DomainService { public IEnumerable<DataA> GetDataA(DateTime? startDate) { /*Pieces together the DataAs that have been created since startDate, and returns them*/ } public DataB GetDataB(int dataAID) { /*Looks up the extended info for that dataAID, constructs a new DataB with that DataA's data, plus the extended info (with multiple DataCs in a List<DataC> property on the DataB), and returns it*/ } //Not exactly sure why these are here, but I think it //wouldn't compile without them for some reason? The data //is entirely read-only, so I don't need to update. public void UpdateDataA(DataA dataA) { throw new NotSupportedException(); } public void UpdateDataB(DataB dataB) { throw new NotSupportedException(); } } The classes for DataA/B/C look like this: [KnownType(typeof(DataB))] public partial class DataA { [Key] [DataMember] public int DataAID { get; set; } [DataMember] public decimal MyDecimalA { get; set; } [DataMember] public string MyStringA { get; set; } [DataMember] public DataTime MyDateTimeA { get; set; } } public partial class DataB : DataA { [Key] [DataMember] public int DataAID { get; set; } [DataMember] public decimal MyDecimalB { get; set; } [DataMember] public string MyStringB { get; set; } [Include] //I don't know which of these, if any, I need? [Composition] [Association("DataAToC","DataAID","DataAID")] public List<DataC> DataCs { get; set; } } public partial class DataC { [Key] [DataMember] public int DataAID { get; set; } [Key] [DataMember] public DateTime Timestamp { get; set; } [DataMember] public decimal MyHistoricDecimal { get; set; } } I guess a big question I have here is... Should I be using Entities instead of POCOs? Are my classes constructed correctly to be able to pass the data down correctly? Should I be using Invoke methods instead of Query (Get) methods on the DomainService? On the client side, I'm having a number of issues. Surprisingly, one of my biggest ones has been threading. I didn't expect there to be so many threading issues with MyDomainContext. What I've learned is that you only seem to be able to create MyDomainContextObjects on the UI thread, all of the queries you can make are done asynchronously only, and that if you try to fake doing it synchronously by blocking the calling thread until the LoadOperation finishes, you have to do so on a background thread, since it uses the UI thread to make the query. So here's what I've got so far. The app should display a stream of the DataA objects, spreading each 3min chunk of them over the next 3min (so they end up displayed 3min after the occurred, looking like a continuous stream, but only have to be downloaded in 3min bursts). To do this, the main form initializes, creates a private MyDomainContext, and starts up a background worker, which continuously loops in a while(true). On each loop, it checks if it has any DataAs left over to display. If so, it displays that Data, and Thread.Sleep()s until the next DataA is scheduled to be displayed. If it's out of data, it queries for more, using the following methods: public DataA[] GetDataAs(DateTime? startDate) { _loadOperationGetDataACompletion = new AutoResetEvent(false); LoadOperation<DataA> loadOperationGetDataA = null; loadOperationGetDataA = _context.Load(_context.GetDataAQuery(startDate), System.ServiceModel.DomainServices.Client.LoadBehavior.RefreshCurrent, false); loadOperationGetDataA.Completed += new EventHandler(loadOperationGetDataA_Completed); _loadOperationGetDataACompletion.WaitOne(); List<DataA> dataAs = new List<DataA>(); foreach (var dataA in loadOperationGetDataA.Entities) dataAs.Add(dataA); return dataAs.ToArray(); } private static AutoResetEvent _loadOperationGetDataACompletion; private static void loadOperationGetDataA_Completed(object sender, EventArgs e) { _loadOperationGetDataACompletion.Set(); } Seems kind of clunky trying to force it into being synchronous, but since this already is on a background thread, I think this is OK? So far, everything actually works, as much of a hack as it seems like it may be. It's important to note that if I try to run that code on the UI thread, it locks, because it waits on the WaitOne() forever, locking the thread, so it can't make the Load request to the server. So once the data is displayed, users can click on one as it goes by to fill a details pane with the full DataB data about that object. To do that, I have the the details pane user control subscribing to a selection event I have setup, which gets fired when the selection changes (on the UI thread). I use a similar technique there, to get the DataB object: void SelectionService_SelectedDataAChanged(object sender, EventArgs e) { DataA dataA = /*Get the selected DataA*/; MyDomainContext context = new MyDomainContext(); var loadOperationGetDataB = context.Load(context.GetDataBQuery(dataA.DataAID), System.ServiceModel.DomainServices.Client.LoadBehavior.RefreshCurrent, false); loadOperationGetDataB.Completed += new EventHandler(loadOperationGetDataB_Completed); } private void loadOperationGetDataB_Completed(object sender, EventArgs e) { this.DataContext = ((LoadOperation<DataB>)sender).Entities.SingleOrDefault(); } Again, it seems kinda hacky, but it works... except on the DataB that it loads, the DataCs list is empty. I've tried all kinds of things there, and I don't see what I'm doing wrong to allow the DataCs to come down with the DataB. I'm about ready to make a 3rd query for the DataCs, but that's screaming even more hackiness to me. It really feels like I'm fighting against the grain here, like I'm doing this in an entirely unintended way. If anyone could offer any assistance, and point out what I'm doing wrong here, I'd very much appreciate it! Thanks!

  • Uploadify Hanging at random on 100%

    - by Matty
    I am using Uploadify (http://www.uploadify.com/) to enable my users to upload images via my web application. The problem I am having is that every now and then (at what appears to be random) when the progress bar reaches 100% it 'hangs' and does nothing. I was wondering if any developers familiar with uploadify may have any idea how to solve this? I am in desperate need of some help. Here is my front-end code: jQuery(document).ready(function() { jQuery("#uploadify").uploadify({ 'uploader' : 'javascripts/uploadify.swf', 'script' : 'upload-file2.php', 'cancelImg' : 'css/images/cancel.png', 'folder' : 'uploads/personal_images/' + profileOwner, 'queueID' : 'fileQueue', 'auto' : true, 'multi' : true, 'fileDesc' : 'Image files', 'fileExt' : '.jpg;.jpeg;.gif;.png', 'sizeLimit' : '2097152', 'onComplete': function(event, queueID, fileObj, response, data) { processPersonalImage(fileObj.name); arrImgNames.push(fileObj.name); showUploadedImages(true); document.getElementById("photos").style.backgroundImage = "url('css/images/minicam.png')"; }, 'onAllComplete' : function() { completionMessage(arrFailedNames); document.getElementById("displayImageButton").style.display = "inline"; document.getElementById("photos").style.backgroundImage = "url('css/images/minicam.png')"; }, 'onCancel' : function() { arrImgNames.push(fileObj.name); arrFailedNames.push(fileObj.name); showUploadedImages(false); }, 'onError' : function() { arrImgNames.push(fileObj.name); arrFailedNames.push(fileObj.name); showUploadedImages(false); } }); }); And server side: if (!empty($_FILES)) { //Get user ID from the file path for use later.. $userID = getIdFromFilePath($_REQUEST['folder'], 3); $row = mysql_fetch_assoc(getRecentAlbum($userID, "photo_album_personal")); $subFolderName = $row['pk']; //Prepare target path / file.. $tempFile = $_FILES['Filedata']['tmp_name']; $targetPath = $_SERVER['DOCUMENT_ROOT'] . $_REQUEST['folder'] . '/'.$subFolderName.'/'; $targetFile = str_replace('//','/',$targetPath) . $_FILES['Filedata']['name']; //Move uploaded file from temp directory to new folder move_uploaded_file($tempFile,$targetFile); //Now add a record to DB to reflect this personal image.. if(file_exists($targetFile)) { //add photo record to DB $directFilePath = $_REQUEST['folder'] . '/'.$subFolderName.'/' . $_FILES['Filedata']['name']; addPersonalPhotoRecordToDb($directFilePath, $row['pk']); } echo "1"; die(true); } thanks for any help!!

  • Possible reasons for tellg() failing?

    - by Andreas Bonini
    ifstream::tellg() is returning -13 for a certain file. Basically, I wrote a utility that analyzes some source code; I open all files alphabetically, I start with "Apple.cpp" and it works perfectly.. But when it gets to "Conversion.cpp", always on the same file, after reading one line successfully tellg() returns -13. The code in question is: for (int i = 0; i < files.size(); ++i) { /* For each .cpp and .h file */ TextIFile f(files[i]); while (!f.AtEof()) // When it gets to conversion.cpp (not on the others) // first is always successful, second always fails lines.push_back(f.ReadLine()); The code for AtEof is: bool AtEof() { if (mFile.tellg() < 0) FATAL(format("DEBUG - tellg(): %d") % mFile.tellg()); if (mFile.tellg() >= GetSize()) return true; return false; } After it reads successfully the first line of Conversion.cpp, it always crashes with DEBUG - tellg(): -13. This is the whole TextIFile class (wrote by me, the error may be there): class TextIFile { public: TextIFile(const string& path) : mPath(path), mSize(0) { mFile.open(path.c_str(), std::ios::in); if (!mFile.is_open()) FATAL(format("Cannot open %s: %s") % path.c_str() % strerror(errno)); } string GetPath() const { return mPath; } size_t GetSize() { if (mSize) return mSize; const size_t current_position = mFile.tellg(); mFile.seekg(0, std::ios::end); mSize = mFile.tellg(); mFile.seekg(current_position); return mSize; } bool AtEof() { if (mFile.tellg() < 0) FATAL(format("DEBUG - tellg(): %d") % mFile.tellg()); if (mFile.tellg() >= GetSize()) return true; return false; } string ReadLine() { string ret; getline(mFile, ret); CheckErrors(); return ret; } string ReadWhole() { string ret((std::istreambuf_iterator<char>(mFile)), std::istreambuf_iterator<char>()); CheckErrors(); return ret; } private: void CheckErrors() { if (!mFile.good()) FATAL(format("An error has occured while performing an I/O operation on %s") % mPath); } const string mPath; ifstream mFile; size_t mSize; }; Platform is Visual Studio, 32 bit, Windows. Edit: Works on Linux. Edit: I found the cause: line endings. Both Conversion and Guid and others had \n instead of \r\n. I saved them with \r\n instead and it worked. Still, this is not supposed to happen is it?

  • jquery accordion - set input focus for active accordion?

    - by KnockKnockWhosThere
    *Nevermind... figured it out... * did it like this: $("#accordion").accordion({ header:'h3', active: '#section1', autoheight: false, clearstyle: true, }).bind("change.ui-accordion", function(event,ui) { $("#text1").focus(); }); I've got an accordion all set up, and each div has a form within it. I'm just trying to figure out how to set the focus on an input field depending on which one is open... /* accordion */ $("#accordion").accordion({ header:'h3', active: '#section1', autoheight: false, clearstyle: true }); Basically, I want to set the cursor in the first input field for whichever section is open. The actual forms are much bigger, so I condensed it enormously... <div id="accordion"> <h3 id="section1"><a href="#">Section 1/a></h3> <div> <form id="form1" action="form.php" method="post"> <fieldset class="inside"> <input type="text" name="text1" id="text1" size="50" value="Default text" /> <input class="open" type="button" value="Submit" name="submit1" /> </fieldset> </form> </div><!--/div--> <h3 id="section2"><a href="#">Section 2</a></h3> <div> <form id="form2" action="form.php" method="post"> <fieldset class="inside"> <input type="text" name="text2" id="text2" size="50" value="Submit" /> <input class="open" type="button" value="Submit" name="submit2" /> </fieldset> </form> </div><!--/div--> <h3 id="section3"><a href="#">Section 3</a></h3> <div> <form id="form3" action="form.php" method="post"> <fieldset class="inside"> <input type="text" name="text3" id="text3" size="50" value="Submit" /> <input class="open" type="button" value="Submit" name="submit3" /> </fieldset> </form> </div><!--/div-->

  • Update Panel error: Control with the ID "xxx" could not be found in the UpdatePanel

    - by George
    I have a composite drop down calendar user control that consists of a textbox and and calendar image and a validation control. I expose a property called "TextBox" on the usercontrol which returns a reference to the textbox used within the control. This is the textbox that the user enters the date into. In the ASPX page, I have an instance of this usercontrol: <uc1:DropDownCalendar ID="dtmDateFirstEntry" runat="server" Required="True" /> In my code behind, I want to detect when a user has tabbed off of the textbox and, using an UpdatePanel, referesh an appropriate message depending on the date that was specified. Elsewhere in the ASPX page I have this: <asp:UpdatePanel ID="upIntendedStay" runat="server"> <ContentTemplate> <asp:Label ID="Label4" runat="server" Text="Update this text from server" CssClass="ErrorText"></asp:Label> </ContentTemplate> </asp:UpdatePanel> Here's what I do in the code behind: If Not Me.IsPostBack Then dtmDateFirstEntry.TextBox.AutoPostBack = True Dim trigger As New AsyncPostBackTrigger trigger.ControlID = dtmDateFirstEntry.TextBox.ClientID trigger.EventName = "onChange" upIntendedStay.Triggers.Add(trigger) End If When the page runs and I view the source, I see something like this: <input id="ctl00_phPageContent_dtmDateFirstEntry_txtDate" class="DefaultTextBox" name="ctl00$phPageContent$dtmDateFirstEntry$txtDate" onchange="javascript:setTimeout('__doPostBack(\'ctl00$phPageContent$dtmDateFirstEntry$txtDate\',\'\')', 0)" onkeypress="if (WebForm_TextBoxKeyHandler(event) == false) return false;" style="width: 112px;" type="text" value="Mar-29-2010" /> <input id="ctl00_phPageContent_dtmDateFirstEntry_imgDate" name="ctl00$phPageContent$dtmDateFirstEntry$imgDate" src="images/calendar.JPG" style="border-width: 0px;" type="image" />&nbsp; When I run it, I get this error: A control with ID 'ctl00_phPageContent_dtmDateFirstEntry_txtDate' could not be found for the trigger in UpdatePanel 'upIntendedStay'. I didn't think that the trigger control had to be within the UpdatePanel. I thought that was the whole point of adding the trigger. How do I refresh this update panel changes to the text in the date usercontrol. Next I will have to add other triggers to trigger the refreshing of the Update Panel from other controls scattered across the page, so clearly all of the trigger sources cannot be within the UpdatePanel.

  • WIA Automation for scanner color intent is not working

    - by Mike Nicholson
    I cannot get my Canon Pixma MP150 to scan a color scan from c# code. The following code is resulting in a black and white image, or if I change the value of 6146 to 2 then a grayscale image is created. I would like to be able to have a color scan from code. I know the scanner does color images because I can do one through the xp wizard in "scanners and camera". Can anyone help me figure out what value I am not setting for a color scan.

  • How can I set fancyBox's contents dynamically?

    - by alex
    I have tried $('.selector').fancybox({ scrolling : 'no', titleShow : false, type : 'inline', content : '<p>hello</p>' But it did not work I have also tried adding the option onComplete: function() { $('#fancybox-inner').html(contents); } Except then when fancyBox is closed, it will not launch again. How can I dynamically set the contents of fancyBox, and retain all of it's functionality? Thanks

  • Android - Getting audio to play through earpiece

    - by Donal Rafferty
    I currently have code that reads a recording in from the devices mic using the AudioRecord class and then playing it back out using the AudioTrack class. My problem is that when I play it out it plays vis the speaker phone. I want it to play out via the ear piece on the device. Here is my code: public class LoopProg extends Activity { boolean isRecording; //currently not used AudioManager am; int count = 0; /** Called when the activity is first created. */ @Override public void onCreate(Bundle savedInstanceState) { super.onCreate(savedInstanceState); setContentView(R.layout.main); am = (AudioManager) getSystemService(Context.AUDIO_SERVICE); am.setMicrophoneMute(true); while(count <= 1000000){ Record record = new Record(); record.run(); count ++; Log.d("COUNT", "Count is : " + count); } } public class Record extends Thread { static final int bufferSize = 200000; final short[] buffer = new short[bufferSize]; short[] readBuffer = new short[bufferSize]; public void run() { isRecording = true; android.os.Process.setThreadPriority (android.os.Process.THREAD_PRIORITY_URGENT_AUDIO); int buffersize = AudioRecord.getMinBufferSize(11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT); AudioRecord arec = new AudioRecord(MediaRecorder.AudioSource.MIC, 11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize); AudioTrack atrack = new AudioTrack(AudioManager.STREAM_MUSIC, 11025, AudioFormat.CHANNEL_CONFIGURATION_MONO, AudioFormat.ENCODING_PCM_16BIT, buffersize, AudioTrack.MODE_STREAM); am.setRouting(AudioManager.MODE_NORMAL,1, AudioManager.STREAM_MUSIC); int ok = am.getRouting(AudioManager.ROUTE_EARPIECE); Log.d("ROUTING", "getRouting = " + ok); setVolumeControlStream(AudioManager.STREAM_VOICE_CALL); //am.setSpeakerphoneOn(true); Log.d("SPEAKERPHONE", "Is speakerphone on? : " + am.isSpeakerphoneOn()); am.setSpeakerphoneOn(false); Log.d("SPEAKERPHONE", "Is speakerphone on? : " + am.isSpeakerphoneOn()); atrack.setPlaybackRate(11025); byte[] buffer = new byte[buffersize]; arec.startRecording(); atrack.play(); while(isRecording) { arec.read(buffer, 0, buffersize); atrack.write(buffer, 0, buffer.length); } arec.stop(); atrack.stop(); isRecording = false; } } } As you can see if the code I have tried using the AudioManager class and its methods including the deprecated setRouting method and nothing works, the setSpeatPoneOn method seems to have no effect at all, neither does the routing method. Has anyone got any ideas on how to get it to play via the earpiece instead of the spaker phone?
