  • able to get the events in fullcalender, but not able to sync these events with time

    - by Ubaid
    i just loved the fullcalendar and wanted to implement it in a small application, everythin worked OK. i am able to get the events from my database through json to the front end. but all events are being listed as "ALL-DAY" events itself. not able to figure out why.. here is the screenshot for the same. any ideas what is going wrong..? i am using asp.net and c#. i have already tried sending the start and end dates in the ToString(), ToShortDateString(), ToString("s"), ToLongDateString(), ToUniversalTime(). nothing seems to working for me at the moment. i tried hard coding and sendin the data too. sample json of my data [{ "id": "2", "title": "Event2", "start": "1274171700", "end": "1274175600" }, { "id": "1", "title": "Event1", "start": "5/18/2010 16:30:00", "end": "5/18/2010 19:30:00" }, { "id": "3", "title": "Event3", "start": "5/18/2010 2:05:00 PM", "end": "5/18/2010 3:10:00 PM" }, { "id": "4", "title": "Event4", "start": "5/18/2010", "end": "5/18/2010" }, { "id": "5", "title": "Event5", "start": "2010-05-18T14:05:00", "end": "2010-05-18T15:10:00" }] all data above has different formats of dates, and at the moment nothing seems to be working. fullcalender accepts the day part fine, but not the time part. not sure why. can anybody help?

  • DataContract Known Types - passing array

    - by Erup
    Im having problems when passing an generic List, trough a WCF operation. In this case, there is a List of int. The example 4 is described here in MSDN. Note that in MSDN sample, is described: // This will serialize and deserialize successfully because the generic List is equivalent to int[], which was added to known types. Above, is the DataContract: [DataContract] [KnownType(typeof(int[]))] [KnownType(typeof(object[]))] public class AccountData { [DataMember] public object accNumber1; [DataMember] public object accNumber2; [DataMember] public object accNumber3; [DataMember] public object accNumber4; } In client side, Im calling the operation like this: DataTransfer.Service.AccountData data = new DataTransfer.Service.AccountData() { accNumber1 = 100, accNumber2 = new int[100], accNumber3 = new List<int>(), accNumber4 = new ArrayList() }; cService.AddAccounts(data); Also, here is the decorations of the generated AccountData obj (WCF proxy): [System.Diagnostics.DebuggerStepThroughAttribute()] [System.CodeDom.Compiler.GeneratedCodeAttribute("System.Runtime.Serialization", "3.0.0.0")] [System.Runtime.Serialization.DataContractAttribute(Name="AccountData", Namespace="http://schemas.datacontract.org/2004/07/DataTransfer.Service")] [System.SerializableAttribute()] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.PurchaseOrder))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(DataTransfer.Client.CustomerServiceReference.Customer))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(int[]))] [System.Runtime.Serialization.KnownTypeAttribute(typeof(object[]))]

  • Worksheet.Unprotect - Office Interop - Difference between 2003 and 2007

    - by sdmcnitt
    I have a .NET winforms app that automates Excel and checks for a worksheet password. The requirements are to be able to detect 1) that the protection is turned off 2) that the password is removed (protected but there is no password) 3) that the password matches the correct password from a database To meet the second requirement the program calls the Worksheet.Unprotect command with a null string, capturing the error. If error as expected, the 3rd check is made. If no error, then the Unprotect worked without a password == password was removed. The code sample below has these checks. The application can do this fine with Office 2003. I have since had my dev machine updated to Office 2007 and it no longer works as it did. When I call the Worksheet.Unprotect, Excel prompts for the password! I need to know how this should be accomplished in the new version of Excel or if there is a way to reference the old PIA. No matter what if I set a reference to Excel 11 it is replaced with the PIA for 12 in the GAC. 'return true if unprotect of worksheet does not generate an error 'all other errors will bubble up 'return false if specific error is "Password is invalid..." Try 'detect unprotected or no password If oWorksheet.ProtectContents Then 'try with no passsword and expect an error 'if no error then raise exception Dim blnRaiseException As Boolean = True Try 'oWorksheet.Unprotect(vbNullString) oWorksheet.Unprotect() Catch ex As Exception blnRaiseException = False End Try If blnRaiseException Then Throw New ExcelSheetNoPasswordException End If oWorksheet.Unprotect(strPwd) 'no error so if we get here -- success fnCheckWorksheetPwd = True 'leave as it was -- this may still cause workbook to think it is changed oWorksheet.Protect(strPwd) Else Throw New ExcelSheetNotProtectedException End If Catch COMex As System.Runtime.InteropServices.COMException 'handle error code -2146827284 If COMex.ErrorCode = -2146827284 Then 'this is the error we're looking for Else Throw End If Catch ex As Exception Throw End Try

  • How do I code Citrix web sites to use a Secure Gateway (CSG)?

    - by RAVolt
    I'm using Citrix's sample code as a base and trying to get it to generate ICA files that direct the client to use their Secure Gateway (CSG) provider. My configuration is that the ICA file's server address is replaced with a CSG ticket and traffic is forced to go to the CSG. The challenge is that both the Citrix App Server (that's providing the ICA session on 1494) and the CSG have to coordinate through a Secure Ticket Authority (STA). That means that my code needs to talk to the STA as it creates the ICA file because STA holds a ticket that the CSG needs embedded into the ICA file. Confusing? Sure! But it's much more secure. The pre-CSG code looks like this: AppLaunchInfo launchInfo = (AppLaunchInfo)userContext.launchApp(appID, new AppLaunchParams(ClientType.ICA_30)); ICAFile icaFile = userContext.convertToICAFile(launchInfo, null, null); I tried to the SSLEnabled information to the ICA generation, but it was not enough. here's that code: launchInfo.setSSLEnabled(true); launchInfo.setSSLAddress(new ServiceAddress("CSG URL", 443)); Now, it looks like I need to register the STA when I configure my farm: ConnectionRoutingPolicy policy = config.getDMZRoutingPolicy(); policy.getRules().clear(); //Set the Secure Ticketing Authorities (STAs). STAGroup STAgr = new STAGroup(); STAgr.addSTAURL(@"http://CitrixAppServerURL/scripts/ctxsta.dll"); //creat Secure Gateway conenction SGConnectionRoute SGRoute = new SGConnectionRoute(@"https://CSGURL"); SGRoute.setUseSessionReliability(false); SGRoute.setGatewayPort(80); SGRoute.setTicketAuthorities(STAgr); // add the SGRoute to the policy policy.setDefault(SGRoute); This is based on code I found on the Citrix Forums; however, it breaks my ability to connect with the Farm and get my application list! Can someone point me to an example of code that works? Or a reference document?

  • Binding XML in Sliverlight without Nominal Classes

    - by AnthonyWJones
    Lets say I have a simple chunck of XML:- <root> <item forename="Fred" surname="Flintstone" /> <item forename="Barney" surname="Rubble" /> </root> Having fetched this XML in Silverlight I would like to bind it with xaml of this ilke:- <ListBox x:Name="ItemList" Style="{StaticResource Items}"> <ListBox.ItemTemplate> <DataTemplate> <StackPanel Orientation="Horizontal"> <TextBox Text="{Binding Forename}" /> <TextBox Text="{Binding Surname}" /> </StackPanel> </DataTemplate> </ListBox.ItemTemplate> </ListBox> Now I can bind simply enough with LINQ to XML and a nominal class:- public class Person { public string Forename {get; set;} public string Surname {get; set;} } So here is the question, can it be done without this class? IOW coupling between the Sliverlight code and the input XML is limited to the XAML only, other source code is agnostic to the set of attributes on the item element. Edit: The use of XSD is suggested but ultimately it amounts the same thing. XSD-Generated class. Edit: An anonymous class doesn't work, Silverlight can't bind them. Edit: This needs to be two way, the user needs to be able to edit the values and these value end up in the XML. (Changed original TextBlock to TextBox in sample above).

  • DataGridView display row header cell

    - by Karl
    I'm trying to display a simple DataGridView linked to a DataTable and I want, ultimately, my first column in the DataTable to be the row header cell for the DataGridView. At this point I will settle for having any value in the row header cell. I can display the DataGridView with all my rows and columns, and with column header cells, but no row header cell. I check the value in the row.HeaderCell.Value, and the data I put there is there. I check row.HeaderCell.Displayed and it is false, but this is read only, so I can't make it true. How do I make the row header cell display? Here's a simple sample of what I've tried to get this to work: DataTable table = new DataTable(); for (int i = 0; i<10; i++) { table.Columns.Add(new DataColumn("column-" + i)); } for (int i = 0; i < 10; i++) { DataRow theRow = table.NewRow(); for (int j = 0; j < 10; j++) theRow[j] = i + "-" + j; table.Rows.Add(theRow); } dataGridView1.DataSource = table; dataGridView1.RowHeadersWidthSizeMode = System.Windows.Forms.DataGridViewRowHeadersWidthSizeMode.AutoSizeToDisplayedHeaders; int rowNumber = 1; foreach (DataGridViewRow row in dataGridView1.Rows) { if (row.IsNewRow) continue; row.HeaderCell.Value = "Row " + rowNumber; rowNumber = rowNumber + 1; } dataGridView1.AutoResizeRowHeadersWidth( DataGridViewRowHeadersWidthSizeMode.AutoSizeToAllHeaders);

  • Problem with header files of ARToolkitPlus after making the ARToolKitPlus dylib!

    - by MNassar
    I'm writing this Augmented Reality app for the iPhone and I'd decided to use ARToolKitPlus for it. Using QMake, I created the xcode project file and subsequently the libArToolKitPlus.dylib I tried to compile and run the sample files "simple" and "multi" which worked well. Now all other attempts that I tried to create another project and use the library have failed due to header files not being found. If I drag the "include" folder to the xcode project I get 8 errors instead of just one; The one is for the main include not being found is solved but then it includes 8 other headers that cannot be found (although they are in the same folder) #include "ARToolKitPlus/TrackerSingleMarkerImpl.h" I get a error: ARToolKitPlus/TrackerSingleMarkerImpl.h: No such file or directory If I drag the include folder then some of what I get: error: ARToolKitPlus/TrackerSingleMarker.h: No such file or directory error: ../src/TrackerSingleMarkerImpl.cpp: No such file or directory error: expected class-name before ',' token class TrackerSingleMarkerImpl : public TrackerSingleMarker, protected TrackerImpl<__PATTERN_SIZE_X,__PATTERN_SIZE_Y, __PATTERN_SAMPLE_NUM, __MAX_LOAD_PATTERNS, __MAX_IMAGE_PATTERNS Having the dylib doesnt make a difference as far as I can tell. What do you think I should do?? Would creating a framework help??

  • Proper way to implement IXmlSerializable?

    - by Greg
    Once a programmer decides to implement IXmlSerializable, what are the rules and best practices for implementing it? I've heard that GetSchema() should return null and ReadXml should move to the next element before returning. Are these true? And what about WriteXml: should it write a root element for the object or is it assumed that the root is already written? How should child objects be treated and written. Here's a sample of what I have now. I'll update it as I get good responses. public class Calendar: IEnumerable<Gvent>, IXmlSerializable { public XmlSchema GetSchema() { return null; } public void ReadXml(XmlReader reader) { if (reader.MoveToContent() == XmlNodeType.Element && reader.LocalName == "Calendar") { _Name = reader["Name"]; _Enabled = Boolean.Parse(reader["Enabled"]); _Color = Color.FromArgb(Int32.Parse(reader["Color"])); if (reader.ReadToDescendant("Event")) { while (reader.MoveToContent() == XmlNodeType.Element && reader.LocalName == "Event") { var evt = new Event(); evt.ReadXml(reader); _Events.Add(evt); } } reader.Read(); } } public void WriteXml(XmlWriter writer) { writer.WriteAttributeString("Name", _Name); writer.WriteAttributeString("Enabled", _Enabled.ToString()); writer.WriteAttributeString("Color", _Color.ToArgb().ToString()); foreach (var evt in _Events) { writer.WriteStartElement("Event"); evt.WriteXml(writer); writer.WriteEndElement(); } } } public class Event : IXmlSerializable { public XmlSchema GetSchema() { return null; } public void ReadXml(XmlReader reader) { if (reader.MoveToContent() == XmlNodeType.Element && reader.LocalName == "Event") { _Title = reader["Title"]; _Start = DateTime.FromBinary(Int64.Parse(reader["Start"])); _Stop = DateTime.FromBinary(Int64.Parse(reader["Stop"])); reader.Read(); } } public void WriteXml(XmlWriter writer) { writer.WriteAttributeString("Title", _Title); writer.WriteAttributeString("Start", _Start.ToBinary().ToString()); writer.WriteAttributeString("Stop", _Stop.ToBinary().ToString()); } }

  • Perl : get substring which matches regex error

    - by Michael Mao
    I am very new to Perl, so please bear with my simple question: Here is the sample output: Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-8008) 2. flightsandroomsonly ($-10102) 3. agent10479475hv ($-10663) Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-7142) 2. agent10479475hv ($-8982) 3. flightsandroomsonly ($-9124) I am interested only in agent names as well as their corresponding balances, so I am hoping to get the following output: agent10896761 -8008 flightsandroomsonly -10102 agent10479475hv -10663 agent10896761 -7142 agent10479475hv -8982 flightsandroomsonly -9124 For later processes. This is the code I've got so far: #!/usr/bin/perl -w open(MYINPUTFILE, $ARGV[0]); while(<MYINPUTFILE>) { my($line) = $_; chomp($line); # regex match test if($line =~ m/agent10479475/) { if($line =~ m/($-[0-9]+)/) { print "$1\n"; } } if($line =~ m/flightsandroomsonly/) { print "$line\n"; } } The second regex match has nothing wrong, 'cause that is printing out the whole line. However, for the first regex match, I've got some other output such like: $ ./compareResults.pl 3.txt 2. flightsandroomsonly ($-10102) 0479475 0479475 3. flightsandroomsonly ($-9124) 1. flightsandroomsonly ($-8053) 0479475 1. flightsandroomsonly ($-6126) 0479475 If I "escape" the braces like this if($line =~ m/\($-[0-9]+\)/) { print "$1\n"; } Then there is never a match for the first regex... So I'm stuck with a problem of making that particular regex work. Any hints for this? Many thanks in advance.

  • Calculating Nearest Match to Mean/Stddev Pair With LibSVM

    - by Chris S
    I'm new to SVMs, and I'm trying to use the Python interface to libsvm to classify a sample containing a mean and stddev. However, I'm getting nonsensical results. Is this task inappropriate for SVMs or is there an error in my use of libsvm? Below is the simple Python script I'm using to test: #!/usr/bin/env python # Simple classifier test. # Adapted from the svm_test.py file included in the standard libsvm distribution. from collections import defaultdict from svm import * # Define our sparse data formatted training and testing sets. labels = [1,2,3,4] train = [ # key: 0=mean, 1=stddev {0:2.5,1:3.5}, {0:5,1:1.2}, {0:7,1:3.3}, {0:10.3,1:0.3}, ] problem = svm_problem(labels, train) test = [ ({0:3, 1:3.11},1), ({0:7.3,1:3.1},3), ({0:7,1:3.3},3), ({0:9.8,1:0.5},4), ] # Test classifiers. kernels = [LINEAR, POLY, RBF] kname = ['linear','polynomial','rbf'] correct = defaultdict(int) for kn,kt in zip(kname,kernels): print kt param = svm_parameter(kernel_type = kt, C=10, probability = 1) model = svm_model(problem, param) for test_sample,correct_label in test: pred_label, pred_probability = model.predict_probability(test_sample) correct[kn] += pred_label == correct_label # Show results. print '-'*80 print 'Accuracy:' for kn,correct_count in correct.iteritems(): print '\t',kn, '%.6f (%i of %i)' % (correct_count/float(len(test)), correct_count, len(test)) The domain seems fairly simple. I'd expect that if it's trained to know a mean of 2.5 means label 1, then when it sees a mean of 2.4, it should return label 1 as the most likely classification. However, each kernel has an accuracy of 0%. Why is this? On a side note, is there a way to hide all the verbose training output dumped by libsvm in the terminal? I've searched libsvm's docs and code, but I can't find any way to turn this off.

  • Why can't I debug from Visual Studio 2005 after installing IE8?

    - by tjrobinson
    I've just installed IE8 (final) and restarted. I can no longer debug Web Application Projects using Visual Studio 2005 on Windows Server 2003 Enterprise R2. I get the message "Internet Explorer cannot display the webpage" and then WebDev.WebServer.exe quits with no visible error message and nothing in the Event Viewer. Does anyone have any ideas? Things that haven't helped: Adding localhost to trusted sites Changing the port to 8080 or 80 Checking my hosts file (it's just got 127.0.0.1 localhost in it) Things that have helped a bit: Running (not debugging) with CTRL-F5, which works fine (unless you need to debug) Changing the default Visual Studio browser to Firefox, which allows me to debug My hosts file contains: # Copyright (c) 1993-1999 Microsoft Corp. # # This is a sample HOSTS file used by Microsoft TCP/IP for Windows. # # This file contains the mappings of IP addresses to host names. Each # entry should be kept on an individual line.

  • Reading a Serial Port - Ignore portion of data written to serial port for certain time

    - by farmerjoe
    I would like to read data coming and Arduino on a serial port on intervals. So essentially something like Take a reading Wait Take a reading Wait Take ... etc. The problem I am facing is that the port will buffer its information so as soon as I call a wait function the data on the serial port will start buffering. Once the wait function finishes I try and read the data again but I am reading from the beginning of the buffer and the data is not current anymore, but instead is the reading taken at roughly the time the wait function began. My question is whether there is a way that I am unaware of to ignore the portion of data read in during that wait period and only read what is currently being delivered on the serial port? I have this something analogous to this so far: import serial s = serial.Serial(path_to_my_serial_port,9600) while True: print s.readline() time.sleep(.5) For explanation purposes I have the Arduino outputting the time since it began its loop. By the python code, the time of each call should be a half second apart. By the serial output the time is incrementing in less than a millisecond. These values do not change regardless of the sleep timing. Sample output: 504 504 504 504 505 505 505 ... As an idea of my end goal, I would like to measure the value of the port, wait a time delay, see what the value is then, wait again, see what the value is then, wait again. I am currently using Python for this but am open to other languages.

  • 3x3 Sobel operator and gradient features

    - by pithyless
    Reading a paper, I'm having difficulty understanding the algorithm described: Given a black and white digital image of a handwriting sample, cut out a single character to analyze. Since this can be any size, the algorithm needs to take this into account (if it will be easier, we can assume the size is 2^n x 2^m). Now, the description states given this image we will convert it to a 512-bit feature (a 512-bit hash) as follows: (192 bits) computes the gradient of the image by convolving it with a 3x3 Sobel operator. The direction of the gradient at every edge is quantized to 12 directions. (192 bits) The structural feature generator takes the gradient map and looks in a neighborhood for certain combinations of gradient values. (used to compute 8 distinct features that represent lines and corners in the image) (128 bits) Concavity generator uses an 8-point star operator to find coarse concavities in 4 directions, holes, and lagrge-scale strokes. The image feature maps are normalized with a 4x4 grid. I'm for now struggling with how to take an arbitrary image, split into 16 sections, and using a 3x3 Sobel operator to come up with 12 bits for each section. (But if you have some insight into the other parts, feel free to comment :)

  • Core Data migration of to-one relationship to to-many relationship

    - by westsider
    I have a deployed app that samples measurements from sensors (e.g., Temp °C, Pressure kPa). The user can create Experiments and collect samples. Each sample is stored as a Run, such that there is a one-to-many relationship from Experiment to Run. In the interest of performance, Run has a to-one relationship with Data entity (which is where the actual raw data is stored); this allows some Run attributes to be loaded without necessarily loading lots of data. Most of our sensors have multiple measurements, so it would be nice to store all the data that is actually being sampled. But this means that the Run <--- Data relationship needs to become Run <-- Data (to use Xcode's convention). I am faced with trying to migrate data from old Run to-one Data model to new Run to-many Data model. Can this be done using Mapping Models? If so, does anyone have any pointers to examples? If not, does anyone have any pointers to examples of how to do that? Thanks for any pointers or advice.

    Given this sample code: #include <iostream> #include <stdexcept> class my_exception_t : std::exception { public: explicit my_exception_t() { } virtual const char* what() const throw() { return "Hello, world!"; } }; int main() { try { throw my_exception_t(); } catch (const std::exception& error) { std::cerr << "Exception: " << error.what() << std::endl; } catch (...) { std::cerr << "Exception: unknown" << std::endl; } return 0; } I get the following output: Exception: unknown Yet simply making the inheritance of my_exception_t from std::exception public, I get the following output: Exception: Hello, world! Could someone please explain to me why the type of inheritance matters in this case? Bonus points for a reference in the standard.

  • OData / WCF Data Service - HTTP 500 Error

    - by Eric
    I have created an OData/WCF service using Visual Studio 2010 on Windows XP SP3 with all current patches installed. When I click on "view in browser", the service opens and I see the 3 tables from my EF model. However, when I add a table name ("Commands" in this case) to the end of the query string, rather than seeing the data from the table, I get an HTTP 500 error. (This error (HTTP 500 Internal Server Error) means that the website you are visiting had a server problem which prevented the webpage from displaying.). I have not only followed the examples from 2 sites, but have also tried running the sample application that the blog poster sent me (that works on his machine), and still am not having any luck. The blog post is at Exposing OData from an Entity Framework Model Does anyone have an idea why this is occurring and how to resolve it? Here is the output of the "View in Browser": <?xml version="1.0" encoding="utf-8" standalone="yes" ?> - <service xml:base="http://localhost:1883/VistaDBCommandService.svc/" xmlns:atom="http://www.w3.org/2005/Atom" xmlns:app="http://www.w3.org/2007/app" xmlns="http://www.w3.org/2007/app"> - <workspace> <atom:title>Default</atom:title> - <collection href="Commands"> <atom:title>Commands</atom:title> </collection> - <collection href="Databases"> <atom:title>Databases</atom:title> </collection> - <collection href="Statuses"> <atom:title>Statuses</atom:title> </collection> </workspace> </service> ============================= Thanks, Eric

  • Oracle JDBC intermittent Connection Issue

    - by Lipska
    I am experiencing a very strange problem This is a very simple use of JDBC connecting to an Oracle database OS: Ubuntu Java Version: 1.5.0_16-b02 1.6.0_17-b04 Database: Oracle 11g Release 11.1.0.6.0 When I make use of the jar file JODBC14.jar it connects to the database everytime When I make use of the jar file JODBC5.jar it connects some times and other times it throws an error ( shown below) If I recompile with Java 6 and use JODBC6.jar I get the same results as JODBC5.jar I need specific features in JODB5.jar that are not available in JODBC14.jar Any ideas Error Connecting to oracle java.sql.SQLException: Io exception: Connection reset at oracle.jdbc.driver.SQLStateMapping.newSQLException(SQLStateMapping.java:74) at oracle.jdbc.driver.DatabaseError.newSQLException(DatabaseError.java:110) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:171) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:227) at oracle.jdbc.driver.DatabaseError.throwSqlException(DatabaseError.java:494) at oracle.jdbc.driver.T4CConnection.logon(T4CConnection.java:411) at oracle.jdbc.driver.PhysicalConnection.(PhysicalConnection.java:490) at oracle.jdbc.driver.T4CConnection.(T4CConnection.java:202) at oracle.jdbc.driver.T4CDriverExtension.getConnection(T4CDriverExtension.java:33) at oracle.jdbc.driver.OracleDriver.connect(OracleDriver.java:474) at java.sql.DriverManager.getConnection(DriverManager.java:525) at java.sql.DriverManager.getConnection(DriverManager.java:171) at TestConnect.main(TestConnect.java:13) Code Below is the code I am using import java.io.; import java.sql.; public class TestConnect { public static void main(String[] args) { try { System.out.println("Connecting to oracle"); Connection con=null; Class.forName("oracle.jdbc.driver.OracleDriver"); con=DriverManager.getConnection( "jdbc:oracle:thin:@172.16.48.100:1535:sample", "JOHN", "90009000"); System.out.println("Connected to oracle"); con.close(); System.out.println("Goodbye"); } catch(Exception e){e.printStackTrace();} } }

  • JACOB (Java/COM/ActiveX) - How to troubleshoot event handling?

    - by Youval Bronicki
    I'm trying to use JACOB to interact with a COM object. I was able to invoke an initialization method on the object (and to get its properties), but am not getting any events back. The code is quoted below. I have a sample HTML+Javascript page (running in IE) that successfully receives events from the same object. I'm considering the following options, but would appreciate any concrete troubleshooting ideas ... Send my Java program to the team who developed the COM object, and have them look for anything suspicious on their side (does the object have a way on knowing whether there's a client listening to its events, and whether they were successfully delivered?) Get into the native parts of JACOB and try to debug on that side. That's a little scary given that my C++ is rusty and that I've never programmed for Windows. public static void main(String[] args) { try { ActiveXComponent c = new ActiveXComponent( "CLSID:{********-****-****-****-************}"); // My object's clsid if (c != null) { System.out.println("Version:"+c.getProperty("Version")); InvocationProxy proxy = new InvocationProxy() { @Override public Variant invoke(String methodName, Variant[] targetParameters) { System.out.println("*** Event ***: " + methodName); return null; } }; DispatchEvents de = new DispatchEvents((Dispatch) c.getObject(), proxy); c.invoke("Init", new Variant[] { new Variant(10), //param1 new Variant(2), //param2 }); System.out.println("Wating for events ..."); Thread.sleep(60000); // 60 seconds is long enough System.out.println("Cleaning up ..."); c.safeRelease(); } } catch (Exception e) { e.printStackTrace(); } finally { ComThread.Release(); } }

Here are a few sample errors.

From looking at all the errors guessing out of the "d" paramter it seems to focus on a single usercontrol on my website. in this control i change the visiblity of div's + text in the usercontrol OnPreRender function. protected override void OnPreRender(EventArgs e) { base.OnPreRender(e); PreparePage(); } Can the errors be related to the usercontrol behavioral? thanks!

  • Production settings file for log4j?

    Here is my current log4j settings file. Are these settings ideal for production use or is there something I should remove/tweak or change?

  • Guice, JDBC and managing database connections

    - by pledge
    I'm looking to create a sample project while learning Guice which uses JDBC to read/write to a SQL database. However, after years of using Spring and letting it abstract away connection handling and transactions I'm struggling to work it our conceptually. I'd like to have a service which starts and stops a transaction and calls numerous repositories which reuse the same connection and participate in the same transaction. My questions are: Where do I create my Datasource? How do I give the repositories access to the connection? (ThreadLocal?) Best way to manage the transaction (Creating an Interceptor for an annotation?) The code below shows how I would do this in Spring. The JdbcOperations injected into each repository would have access to the connection associated with the active transaction. I haven't been able to find many tutorials which cover this, beyond ones which show creating interceptors for transactions. I am happy with continuing to use Spring as it is working very well in my projects, but I'd like to know how to do this in pure Guice and JBBC (No JPA/Hibernate/Warp/Reusing Spring) @Service public class MyService implements MyInterface { @Autowired private RepositoryA repositoryA; @Autowired private RepositoryB repositoryB; @Autowired private RepositoryC repositoryC; @Override @Transactional public void doSomeWork() { this.repositoryA.someInsert(); this.repositoryB.someUpdate(); this.repositoryC.someSelect(); } } @Repository public class MyRepositoryA implements RepositoryA { @Autowired private JdbcOperations jdbcOperations; @Override public void someInsert() { //use jdbcOperations to perform an insert } } @Repository public class MyRepositoryB implements RepositoryB { @Autowired private JdbcOperations jdbcOperations; @Override public void someUpdate() { //use jdbcOperations to perform an update } } @Repository public class MyRepositoryC implements RepositoryC { @Autowired private JdbcOperations jdbcOperations; @Override public String someSelect() { //use jdbcOperations to perform a select and use a RowMapper to produce results return "select result"; } }

  • How to know $(window).load(); status from jquery

    - by Starx
    I have created a website loading bar using Jquery UI Progress bar, this progress bar shows the status of scripts loading. A sample is $.getScript('_int/ajax.js',function() { $("#progressinfo").html("Loading Complete ..."); $("#progressbar").progressbar({ value: 100 }); }); This progress bar is in #indexloader which is blocking the website being loaded behind, its CSS is #indexloader { z-index:100; position:fixed; top:0; left:0; background:#FFF; width:100%;height:100%; } After the progress bar reaches 100% I want to hide and remove #indexloader for that I used $("#indexloader").fadeOut("slow",function() { $("#indexloader").remove(); }); But the problem is, although the scripts have loaded, the pages are not fully loaded, I see images and other things still loading. So before fading and removing the #indexloader i want to check whether the $(window).load() has completed or not Is there a way to check this? Thanks in advance
