• Strophe javascript prevent disconnection on some delay

  - by patrikas

  Hello, I am developing javascript XMPP application which uses Strophe library to connect to Jabber server. I need to engage the thread for about 5-10 seconds when Strophe connects to the server. Thread is engaged by running java applet and after it releases the thread it goes back to handle XMPP events, however at the moment I cannot manage to do that - trying to use a connection after delay gives me 404 HTTP error (this is sent by XMPP-BOSHS service straight after Strophe sends POST request with XMPP message to it). I was trying to 'pause' a connection with Strophe's connection.pause and then resume it - didn't work. Would sending some raw content to the server, maybe if it's possible telling it that client's gonna be unresponsive for a short time work ? Are there any other solutions ? Thanks

• How to automate the finding of an M value along a route

  - by Heather Taylor

  Kirk Kuykendall had given a script example a few years back in an ESRI forum http://forums.esri.com/Thread.asp?c=93&f=996&t=88246&mc=4 as to how to find the M (measure) value of a point in a shapefile along a route when you clicked on the point. This is very handy, BUT..I have 1500 points that I need M values for. Is there a way to automate this type of thing? I need the M values for the points to create linear events on the route. Note: I am not a programmer, but have people who can help me out.

• How to get notified when a folder is accessed?

  - by smwikipedia

  I have a shared folder on my local machine. I want to get notified every time someone tries to access it. Could someone give me some hint on this? I have checked the FileSystemWatcher class, it only provides events for change/creation/delete/rename of the contents under the folder, which is not exactly what I want. I also tried to use the event log audition as shown here, but it is just not exactly what I want, either. Many thanks.

• Embedding Python and adding C functions to the interpreter

  - by monoceres

  I'm currently writing an applications that embedds the python interpreter. The idea is to have the program call user specified scripts on certain events in the program. I managed this part but now I want the scripts to be able to call functions in my program. Here's my code so far: #include "python.h" static PyObject* myTest(PyObject* self,PyObject *args) { return Py_BuildValue("s","123456789"); } static PyMethodDef myMethods[] = {{"myTest",myTest},{NULL,NULL}}; int main() { Py_Initialize(); Py_InitModule("PROGRAM",myMethods); PyRun_SimpleString("print PROGRAM.myTest()"); Py_Finalize(); } Thanks!

• Using CreateFileMapping between two programs - C

  - by Jamie Keeling

  Hello, I have two window form applications written in C, one holds a struct consisting of two integers, another will receive it using the CreateFileMapping. Although not directly related I want to have three events in place so each of the processes can "speak" to each other, one saying that the first program has something to pass to the second, one saying the first one has closed and another saying the second one has closed. What would be the best way about doing this exactly? I've looked at the MSDN entry for the CreateFileMapping operation but I'm still not sure as to how it should be done. I didn't want to start implementing it without having some sort of clear idea as to what I need to do. Thanks for your time.

• How can I utilize or mimic Application OnStart in an HttpModule?

  - by Sailing Judo

  We are trying to remove the global.asax from our many web applications in favor of HttpModules that are in a common code base. This works really well for many application events such as BeginRequest and PostAuthentication, but there is no Application Start event exposed in the HttpModule. I can think of a couple of smelly ways to overcome this deficit. For example, I can probably do this: protected virtual void BeginRequest(object sender, EventArgs e) { Log.Debug("Entered BeginRequest..."); var app = HttpContext.Current.Application; var hasBeenSet app["HasBeenExecuted"] == null ? false : true; if(!hasBeenSet) { app.Lock(); // ... do app level code app.Add("HasBeenSet", true); app.Unlock(); } // do regular begin request stuff ... } But this just doesn't smell well to me. What is the best way to invoke some application begin logic without having a global.asax?

• Javascript Split: without losing character

  - by Rohan

  I want to split certain text using JavaSscript. The text looks like: 9:30 pm The user did action A. 10:30 pm Welcome, user John Doe. 11:30 am Messaged user John Doe Now, I want to split the string into events. i.e.: 9:30 pm The user did action A. would be one event. I'm using RegEx for this: var split = journals.split(/\d*\d:/); Thing is, the first two characters are getting lost. The split appears like this: 30 pm The user did action A. How do I split so that the split maintains the first two/three characters (ie 9: or 10:) etc? Thanks!

• Client or server side invocation to google API?

  - by Raffo

  I'm writing a web application with GWT and I've to call google calendar's API to retrieve some information. I now have this dilemma: Is it better to use a client side invocation (using javascript or gwt-gdata library) or using the standard google library for java to call the service at server side and then passing all the data to the client via an async call?? I'm not able to understand pros and cons of the two approaches... In particular, I need to call several time the calendar API to retrieve events and let users add new ones, etc. Can you help me?

• Log with timestamps that have millisecond accuracy & resolution in Windows C++

  - by Psychic

  I'm aware that for timing accuracy, functions like timeGetTime, timeBeginPeriod, QueryPerformanceCounter etc are great, giving both good resolution & accuracy, but only based on time-since-boot, with no direct link to clock time. However, I don't want to time events as such. I want to be able to produce an exact timestamp (local time) so that I can display it in a log file, eg 31-12-2010 12:38:35.345, for each entry made. (I need the millisecond accuracy) The standard Windows time functions, like GetLocalTime, whilst they give millisecond values, don't have millisecond resolution, depending on the OS running. I'm using XP, so I can't expect much better than about a 15ms resolution. What I need is a way to get the best of both worlds, without creating a large overhead to get the required output. Overly large methods/calculations would mean that the logger would start to eat up too much time during its operation. What would be the best/simplest way to do this?

• Variable width columns in a table

  - by Jack

  I'm using an HTML table for a calendar and I want to fill the cells with various events from my database. Usually they will land on weekends but some will run for long weekend, bank holidays or even the odd week day. How can I get my tables columns to expand and shrink accordingly. I'd like to avoid the use of javascript if possible. If this can't be done I'm going to need a tutorial to help me get my head around how to make div's positioning behave. cheers

• How can I display a dialog box for making a choice before a CALL is processed in android?

  - by jsight

  I would like to intercept outgoing calls and pass them to a VOIP application. I see that the Google Voice application has a feature for displaying a question before each call is actually initiated. It provides the user with the choice: Initiate call via Google Voice Initiate call via standard call I would like a way to do something similar with my application (so that not all calls have to be routed through it). At the moment, I can intercept CALL events via a BroadcastReceiver, however, these are not allowed to open dialogs (thus making it possible to display the choice). What is the best way of achieving this goal?

• Form Inheritance in Visual Studios designer implementations

  - by CooPzZ

  I'm in the process of Moving a project from Visual Studio 2003 to 2005 and have just seen the The event Click is read-only and cannot be changed when using inherited forms regardless of the Modifier on the Base Forms Controls will make all the Controls from the Base Readonly in the designer (Though in 2003 it didn't work this way). I found this post metioning that this functionality has been temporarily" disabled http://social.msdn.microsoft.com/Forums/en-US/winformsdesigner/thread/c25cec28-67a5-4e30-bb2d-9f8dbd41eb3a Can anyone confirm whether this feature is used anymore? or how to program around it to be able to use the Base Control Events and still have a designer? This is one way I've found but quite painfull when it used to do the plumbing for you. even just hiding one of the controls you have manually do now. Public Class BFormChild Friend Overrides Sub cmdApply_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdApply_Click(sender, e) End Sub Friend Overrides Sub cmdCancel_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdCancel_Click(sender, e) End Sub Friend Overrides Sub cmdOk_Click(ByVal sender As Object, ByVal e As System.EventArgs) MyBase.cmdOk_Click(sender, e) End Sub End Class

• How to cause bindings to be updated, particularly for derived values?

  - by rrhartjr

  I'm using some CLR objects that use the INotifyPropertyChanged interface and use the PropertyChanged function to update in WPF bindings. Pretty boilerplate: protected void RaisePropertyChanged(string propertyName) { if (PropertyChanged != null) { PropertyChanged(this, new PropertyChangedEventArgs(propertyName)); } } Then the property: private double m_TotalWidgets = 0; public double TotalWidgets { get { return m_TotalWidgets; } set { m_TotalWidgets = value; RaisePropertyChanged("TotalWidgets"); } } Is there a better way to update a derived value or even the whole class? Say I had a calculated value: public double ScaledWidgets { get { return TotalWidgets * CONSTANT_FACTOR; } } I would have to fire ScaledWidget's PropertyChanged when TotalWidgets is updated, eg: set { m_TotalWidgets = value; RaisePropertyChanged("TotalWidgets"); RaisePropertyChanged("ScaledWidgets"); } Is there a better way to do this? Is it possible "invalidate" the whole object, especially if there are a lot of derived values? I think it would be kind of lame to fire 100 PropertyChanged events.

• Remove items from SWT tables

  - by Dima

  This is more of an answer I'd like to share for the problem I was chasing for some time in RCP application using large SWT tables. The problem is the performance of SWT Table.remove(int start, int end) method. It gives really bad performance - about 50msec per 100 items on my Windows XP. But the real show stopper was on Vista and Windows 7, where deleting 100 items would take up to 5 seconds! Looking into the source code of the Table shows that there are huge amount of windowing events flying around in this call.. That brings the windowing system to its knees. The solution was to hide the damn thing during this call: table.setVisible(false); table.remove(from, to); table.setVisible(true); That does wonders - deleting 500 items on both XP & Windows7 takes ~15msec, which is just an overhead for printing out time stamps I used. nice :)

• Customize Annotation problem....Plz Help.. !!

  - by user128647

  I want to show my custom UIView(.Xib View) to appear when user tabbed on pins (not apple's callOutBubble) and in that UIView there should be a button which fires an IBAction on touched down event. Therefore i have added an AddObserver method to MKAnnotationView. which responds to touch events over pin in MKMapView. But i have also added 3 buttons over that XIB view, which have also assined IBActions. But when i run application, Buttons in Customized Annotation view are not responding to IBAction (Touch Down)? Why this happens ?? What is the solution for that??? I need to have called some method, when those 3 buttons tabbed. Thanks

• Gridview with row being edited causing error when form submitted

  - by Chris Phelps

  Using ASP.NET VB, I have a form with some text boxes and a Gridview. If a user clicks the Edit button on a row in the gridview, and then tries to submit the form with a row still in edit mode on the Gridview, this error is generated - "Invalid postback or callback argument. Event validation is enabled using in configuration or <%@ Page EnableEventValidation="true" % in a page. For security purposes, this feature verifies that arguments to postback or callback events originate from the server control that originally rendered them. If the data is valid and expected, use the ClientScriptManager.RegisterForEventValidation method in order to register the postback or callback data for validation. " Any idea how to prevent this error??

• Can jQuery UI's Sortable handle complex selectors for the items option?

  - by jverdi

  I have list items in an unordered list that when double clicked, can be edited in place via a wysiwyg editor. $('ul.mtm_section').sortable({ disabled: true, distance: 10, items: '> li:not(:has(form))' }); My goal is to prevent the list item from being sorted while it is being edited - aka once a form element has been swapped in place of the contents. Unfortunately my selector for items is not working. Is sortable able to handle complex selectors like these? If not, are there other clever means to disable some items from being sortable, perhaps a callback function? I would prefer to rely on this sortable option, as the wysiwyg plugin is deeply nested with jEditable and as far as I know does not open up any events for me to hook into. Using jQuery 1.4.2 and jQuery UI 1.8.1

• Using CreateWindow() to make additional Window on a thread - C

  - by Jamie Keeling

  Hello, I have a windows form that has a simple menu and performs a simple operation, I want to be able to create another windows form with all the functionality of a menu bar, message pump etc.. as a separate thread so I can then share the results of the operation to the second window. I.E. 1) Form A opens Form B opens as a separate thread 2)Form A performs operation 3)Form A passes results via memory to Form B 4)Form B display results I'm confused as to how to go about it, the main app runs fine but i'm not sure how to add a second window if the first one already exists. I think that using CreateWindow will allow me to make another window but again i'm not sure how to access the message pump so I can respond to certain events like WM_CREATE on the second window. I hope it makes sense. Thanks!

• iPhone Input with Stacked Views

  - by Forrest

  Hi, I've got a situation in an iphone application where buttons are not receiving input as I expect. Here's the setup: ViewMain - The main view full of various images and labels ViewOverlay - A HUD like overlay view with two UIButton objects. To create my scene I do the following: viewController.view = ViewMain [ViewMain addsubview:ViewOverlay] This view renders as expected, with ViewOverlay correctly rendered ontop of ViewMain. However the two buttons found inside ViewOverlay do not receive touch events and can not be pressed. Tapping them does nothing at all. I very well may be going about this in the entirely wrong direction. Any ideas?

• Creating a ListView using Category (Control Panel-Like) View

  I currently have an application which uses a regular ListView with groups to show a bunch of modules. I would like to use a Category view. Category view is the new view introduced in Windows Vista for the Control Panel: Is there a third party control or a way (via API) to create a ListView which mimics the behavior of the Windows 7 Control Panel? Categories with icons and action links. Separate events for Category Click and Action Click. One or two column layout Separators between action links or lines

• Implementing a multi-state planner

  - by MoominTroll

  I've been asked to develop a system wherein employees can mark on a form their availability on a given day of the week - for instance an employee could mark themselves as available on a given time on a given week, and unavailable on some other time. It looks a little like this: Currently this works by rendering checkboxes within the table, picking up click events in each cell and marking the checkbox and hence the cell appropriately. I'm using the JQuery "click n drag checkbox" plugin from here. However, I've been informed that there could well be more than two states for a given cell (for instance available, unavailable, available in a given circumstance), in which case binding to a checkboxes checked value isnt going to be a lot of help. I've never used javascript or asp.net before and am unsure as to the best way to approach this problem. Ideally I could stick a data structure behind each cell which I could update to a certain state and then get my cell colour by binding to this - however I'm at something as a loss as how to best achieve this.

• How can I stop a default event when using a named function in addEvent?

  - by Rupert

  Normally, if I wish to stop a default event in mootools I can do this: $('form').addEvent('submit', function(e) { e.stop(); //Do stuff here } However, I don't like using an anonymous function in events because I often want to reuse the code. Lets say I have a validate function. I could do this: $('form').addEvent('submit', validate); which works fine until I want to stop the default event. validate obviously doesn't know what e is so I can't just do e.stop(). Also I've tried passing the event as a variable to validate but whenever I use a named function with parameters, the function gets called automatically on domready, rather than on the event firing. Even worse, an error is thrown when the event is fired: What am I doing wrong?

• Prevent painting of .NET form while form is loading?

  - by dvcolgan

  Is there a way to turn off all visual updates to a .NET form while I am manipulating it? When my program first loads, for example, I set the tab control to the tab that was last open. The user can see the program switching tabs. I have looked into SuspendLayout and ResumeLayout, but either I don't understand what they are doing, or I am not using them correctly, because they don't seem to have any effect. Someone told me that there used to be a way to turn off paint events in VB 6. Does this still exist in .NET?

• Official way to ask jQuery wait for all images to load before executing something

  - by Simon_Weaver

  In jQuery when you do this: $(function() { alert("DOM is loaded, but images not necessarily all loaded"); }); It waits for the DOM to load and executes your code. If all the images are not loaded then it still executes the code. This is obviously what we want if we're initializing any DOM stuff such as showing or hiding elements or attaching events. Let's say though that I want some animation and I don't want it running until all the images are loaded. Is there an official way in jQuery to do this? The best way I have is to use <body onload="finished()">, but I don't really want to do that unless I have to. Note: There is a bug in jQuery 1.3.1 in Internet Explorer which actually does wait for all images to load before executing code inside $function() { }. So if you're using that platform you'll get the behavior I'm looking for instead of the correct behavior described above.
