• How can i add an image in html email from lotus domino agent?

  - by mike_x_

  i want to add a simple image into an email which i want to send from a lotus agent. I paste below a part of the code: StringBuilder sb = new StringBuilder(); sb.append("<div><img src=\"http://goo.gl/lziMZN\"></div>"); email.setHTMLPart(sb.toString()); email.send("[email protected]"); I also tried to use an image from my image resources in the nsf. Whatever i tried i get an empty image area (browser-no-image icon) in the email i receive. I also have checked "Allow restricted operations" in my agent. I would prefer it if there is a solution to use an image from my resources and not an external link. Any solutions?

• Error 3032 during EF 4.0 validation

  - by Mohammadreza

  Hi guys. I have a table that has a column called "rowguid" with default value of newguid(). After I delete the generated property in the Entity Framework 4.0 designer, whenever I try to build or validate the model I receive the following error message. Error 3023: Problem in mapping fragments starting at line 1460:Column People.rowguid in table People must be mapped: It has no default value and is not nullable. It's an obvious error message but the problem is that the column HAS default value. Does anyone knows what the problem is? Thanks.

• Eclipse Plugin: Enablement of an Action based on the current selection

  - by Itay

  I am using the org.eclipse.ui.popupMenus extension point for adding a sub-menu whose Action that is bounded to the following class: public class MyAction implements IObjectActionDelegate { private Logic logic = Logic.getInstance(); // Singleton public void setActivePart(IAction a, IWorkbenchPart targetPart) { // Nothing here } public void run(IAction a) { // Do something... } public void selectionChanged(IAction a, ISelection s) { a.setEnabled(logic.isEnabled(s)); } } This action is working correctly in most cases (including the call a.setEnabled() in selectionChanged()). My problem at the very first time my action is being invoked. The selectionChanged method is called only after the menu item has been displayed (and not when the user has made the selection) which means that the call to a.setEnabled() will have no affect. Any ideas on how to make my action receive selectionChanged() notifications even before the fist time it is being invoked?

• Posting within PHP and receiving only cookie

  - by faya

  Hello I have a question. It might be sound ridiculous, but let me explain what I want to accomplish. Right now I try to embed open source forum to by site and I want to leave forum and my site databases split. When my site users are logging in I want them also automatically be logged in to the forum system. For that I want to login within my PHP code after receiving username and password in post, but I don't know how I can get only cookies in response. I have found out that I can use curl_init(), curl_exec(), curl_close() functionality, but response from curl_exec returns whole response(page content, cookies, headers). Is there a way to receive only cookies? P.S. - If my design is totally wrong please give an advise how I can embed this functionality! I would be very thankful!

• pointer being freed was not allocated

  - by kudorgyozo

  Hello i have the following error: malloc: * error for object 0x2087000: pointer being freed was not allocated * set a breakpoint in malloc_error_break to debug I have no idea what object that is. I don't know how to find it. Can anybody explain to me how (and where) to use malloc_history. I have set a breakpoint in malloc_error_break but i couldn't find out what object is at that address. I receive this after removing an object from an nsmutablearray and popping a view controller manually. If I comment out the line [reviewUpload.images removeObject: self.reviewUploadImg] it doesn't give me the error but of course it's not useful for me like that. - (void) removeImage { debugLog(@"reviewUploadImg %@", self.reviewUploadImg); debugLog(@"reviewUpload %@", self.reviewUpload); debugLog(@"reviewUploadImg thumb %@", self.reviewUploadImg.thumb); [reviewUpload.images removeObject: self.reviewUploadImg]; [self.navigationController popViewControllerAnimated:TRUE]; }

• Sending url params and POST body to a MVC 2 Controller

  - by Luiggi

  Hi, I'm having some issues trying to make a HTTP PUT (or POST) using WebClient against a MVC 2 controller. The exception is: The parameters dictionary contains a null entry for parameter 'total' of non-nullable type 'System.Int32' for method 'System.Web.Mvc.ActionResult Company(System.Guid, Int32, Int32, System.String)' The controller action is: [HttpPut] public ActionResult Company(Guid uid, int id, int total, string url) The route is: routes.MapRoute( "CompanySet", "job/active/{uid}/company/{id}", new { controller = "Job", action = "Company" } ); As you may see, what I want is to send the 'uid' and 'id' parameters via url, but the 'total' and 'url' parameters as part of the PUT or POST body. I've also tried to merge the latter parameters into a class (i.e., CompanySetMessage), doing it no longer raises an exception but I dont receive the values on the server side. Any ideas? Thank you!

• Erlang message loops

  - by Roger Alsing

  How does message loops in erlang work, are they sync when it comes to processing messages? As far as I understand, the loop will start by "receive"ing a message and then perform something and hit another iteration of the loop. So that has to be sync? right? If multiple clients send messages to the same message loop, then all those messages are queued and performed one after another, or? To process multiple messages in parallell, you would have to spawn multiple message loops in different processes, right? Or did I misunderstand all of it?

• GameKit server disconnect makes session invalid

  - by Markus

  Hi everyone, I'm trying to build a 4 player multiplayer game using GameKit. I tried many things and I'm currently using client/server mode, meaning that I have 1 session in GKSessionModeServer and 3 other sessions connecting to this one in GKSessionModeClient. My goal is, that when a user leaves the game or gets disconnected for whatever reason, that the others can continue their game. So far this works if any of the Clients leave the game, but if the Sevrer leaves the game, send and receive calls are not reaching the other peers anymore. I tried the same with 4 peers in GKSessionModePeer with the same result (where the player who accepts connections cannot quit). Does anyone had better success in making this work? Any help is highly appreciated. Thanks!

• jQuery-ajax call: async property is not working?

  - by user269386

  Hi, given to certain circumstances, I'm forced to keep page settings (Javascript-values) in the session and it has to be done right before leaving the page (I can't use cookies, since "pageSettings" can become quite large and localStorage is not an option yet ;) ). So this is how I tried it. However it seems that when I call the page directly again, the call of "http://blabla.com/bla" happens asynchronous, even though the async-attribute is set (I don't receive the settings of the previous call, but of the one before): $jQ(document).ready(function () { $jQ(window).unload(Main.__setSessionValues); }); var Main = { pageSettings: {}, __setSessionValues: function __setSessionValues() { $jQ.ajax({ type: "POST", async: false, url: "http://blabla.com/bla", data: { pageSettings: Object.toJSON(Main.pageSettings) } }); } }; Does anyone know what the problem might be? thanks in advance

• How to ensure YouTube API only returns videos that are playable on iPhone?

  - by prendio2

  I'm building some YouTube search functionality into an iPhone app and want to ensure that I only receive results that will be playable on the device. According to the Searching for videos section in the API reference doc this seems to be relatively straightforward: The format parameter specifies that videos must be available in a particular video format. Your request can specify any of the following formats: I've currently set my project to only return videos with "format=1" which will limit to: RTSP streaming URL for mobile video playback. H.263 video (up to 176x144) and AMR audio. I'd love if someone could confirm that this is in fact the appropriate setting or let me know if I'm missing something. Cheers.

• Doxygen comments on declarations or on definitions?

  - by Arkaitz Jimenez

  Just started using Doxygen for documenting my code here and can't decide where to put them. At first look it seems better to put them in the declaration files as it is there where you actually declare what you receive, what you are going to return and stuff like that, apart from that things like data members that are only in the declaration files can obviously only documented there. But often I find handier to comment methods in the implementation files as they are more accessible to me and the declaration file doesn't get cluttered with dozens of lines of comments making it harder to find what you look for when developing. What is your experience with that?

• How can I pass a javaScript function to a Java Method to act as a callback (Rhino)

  - by Dan Howard

  Hi everyone, Basically I'm trying to pass a javaScript function to a Java method to act as a callback to the script. I can do it - sort of - but the object I receive is a sun.org.mozilla.javascript.internal.InterpretedFunction and I don't see a way to invoke it. Any ideas? Here's what I have so far: var someNumber = 0; function start() { // log is just an log4j instance added to the Bindings log.info("started...."); someNumber = 20; // Test is a unit test object with this method on it (taking Object as a param). test.callFromRhino(junk); } function junk() { log.info("called back " + someNumber); }

• How communicate with pty via minicom or screen?

  - by gscott2112

  I am trying to provide an AT/Modem-like interface around some hardware. Follwing this post I have the server setting up a pty using openpty(). Now I can communicate with the server as expected with a client app that open the slave and communicates via read() and write() calls. However I would also like to be able to use either the screen command or minicom to issue commands by hand to the slave. However the server never seems to receive any data when trying to do this. Is there something significant I am missing with this approach?

• limit of connections with database and number of java threads in an application

  - by Jyoti

  Hi, I am working to develop a JMS application(stand alone multithreaded java application) which can receive 100 messages at a time , they need to be processed and database procedures need to be called for inserting/updating data. Procedures are very heavy as validations are also performed in them. Each procedure is taking about 30 to 50 seconds of time to execute and they are capable to run concurrently. My concern is to execute 100 procedures for all 100 messages and also send reply within time limit of 90 seconds by jms application. No application server to be used(requirement) and database is Teradata (RDBMS) I am using connection pool and thread pool in java code and testing code with 90 connections. Question is : (1) What should be the limit on number of connections with database at a time? (2) How many threads at a time are recommended? Thanks, Jyoti

• How to get current directory in C# for any Windows version?

  - by DarthRoman

  I am creating an application that can be executed in any windows version, even in mobile's, and I am trying to get the current directory of the executable. The problem is that if I use the following code, it doesn't compile in Windows Mobile: string currentDirectory = System.IO.Path.GetDirectoryName(System.Windows.Forms.Application.ExecutablePath); And if I use this code, I receive something like: file:\C:\xxx string currentDirectory = System.IO.Path.GetDirectoryName(System.Windows.Forms.Application.ExecutablePath); Although, I need to get the root drive, and this code doesn't compile in Windows Mobile: String rootPath = Path.GetPathRoot(Environment.SystemDirectory); Does anyone know how to get the current directory of the application and the root path for any windows version, even mobile's?

• How can I provide links to intranet files through ASP.net?

  - by PhoenixWright

  Conditions: The files must be opened outside of the window that the link to them is in. I have tried href, but when I give it an intranet link it only opens correctly if I leave out target="_blank"; if I put that in, the new window that opens doesn't receive the full link if there is a pound sign in the filepath... a direct link to the intranet address \a\b\c#c.txt would be fine with me; there is no concern about security, but I can't seem to get that to happen in a new window. It seems like this is happening when I don't create a new window, but I can't utilize the same window to open the links. Any ideas?

• Best approach to send data from a server to an Android device

  - by ElectricDialect

  I am developing an Android app that needs to communicate bi-directionally with a server. By that, I mean either the server or the device can send a message at any time, with an arbitrary amount of time in between messages. Sending data from the device to the server is a common and I think well understood task, but I'm not as sure what the best approach is to go in the opposite direction from the server to the device. I think having the device periodically poll the server may be a bad idea due to latency and the drain on the battery, but I'd be willing to consider this option. My plan at the moment is to send text messages from the server via an email-to-SMS bridge, and to have my app run a service to receive and handle these messages. The question I have is if there are any best practices for this scenario, and if using text messages has some downsides that I have failed to consider. For the sake of this question, I want to assume that users have an unlimited text data plan, so paying per text won't be an issue.

• Problems with IRQs when connecting two digium card in and asterisk box

  - by JorgeO

  I have two Digium Wildcard TDM800P with 8 FXO ports each. When I connect both at the same time IRQ misses start showing up making my computer unresponsive and unusable. One card works fine but I need all 16 FXO ports to work to receive calls from my Telco. Is there a way for the cards to communicate with each other so they don't generate as many interrupts. Or a way to tweak Linux to dedicate separate IRQ's for each card. I have tried disabling Audio, ACPI and USB ports. Still too many IRQ misses.

• In .NET, what thread will Events be handled in?

  - by Ben

  I have attempted to implement a producer/consumer pattern in c#. I have a consumer thread that monitors a shared queue, and a producer thread that places items onto the shared queue. The producer thread is subscribed to receive data...that is, it has an event handler, and just sits around and waits for an OnData event to fire (the data is being sent from a 3rd party api). When it gets the data, it sticks it on the queue so the consumer can handle it. When the OnData event does fire in the producer, I had expected it to be handled by my producer thread. But that doesn't seem to be what is happening. The OnData event seems as if it's being handled on a new thread instead! Is this how .net always works...events are handled on their own thread? Can I control what thread will handle events when they're raised? What if hundreds of events are raised near-simultaneously...would each have its own thread?

• how to save the compose message text in draft automatically ?

  - by ahmed

  Hello, we have a vb.net application with send and receive mailing also. Now we have added a session timer of 30 min but the users are complaining that they are facing a problem when they write a long text message or while composing they get busy in something else and when they return back to continue composing message , they are redirected to a session expiry page, and their long text message is gone forever. So I am new to this and I was thinking like , when the user is in compose message the text should be automatically saved to drafts like hotmail. Any help will be appreciated . Thank you.

• Haskell: writing the result of a computation to file

  - by peterwkc

  I have a function which creates a tuple after computation, but I would like to write it to file. I know how to write to a file using writeFile, but do not know how to combine the computation and monads IO together in the type signature. This is my code. invest :: ([Char]->Int->Int->([Char], Int) ) -> [Char]->Int->Int->([Char], Int) invest myinvest x y = myinvest x y myinvest :: [Char]->Int->Int->([Char], Int) myinvest w x y | y > 0 = (w, x + y) | otherwise = error "Invest amount must greater than zero" where I have a function which computes the maximum value from a list, but I want this function to receive input from a file, and then perform the computation of maximum value. maximuminvest :: (Ord a) => [a] -> a maximuminvest [] = error "Empty Invest Amount List" maximuminvest [x] = x maximuminvest (x:xs) | x > maxTail = x | otherwise = maxTail where maxTail = maximuminvest xs Please help. Thanks.

• Boost Filesystem Library Visual C++ Compile Error

  - by John Miller

  I'm having the following issue just trying to compile/run some of the example programs with the Boost Filesystem Library. I'm using MS-Visual C++ with Visual Studio .NET (2003). I've installed the Boost libraries, version 1.38 and 1.39 (just in case there was a version problem) using the BoostPro installers. If I just try to include /boost/filesystem/operations.hpp I receive the following error: \boost_1_38\boost\system\error_code.hpp(230) : error C2039: 'type' : is not a member of 'boost::enable_if<boost::system::is_error_condition_enum<Cond,boost::detail::enable_if_default_T>' Any help is greatly appreciated.

• How to change FPU context in signal handler (C++/Linux)

  - by Henry Fané

  I wrote a signal handler to catch FPE errors. I need to continue execution even if this happens. I receive a ucontext_t as parameter, I can change the bad operand from 0 to another value but the FPU context is still bad and I run into an infinite loop ? Does someone already manupulate the ucontext_t structure on Linux ? I finally found a way to handle these situations by clearing the status flag of ucontext_t like this: ... const long int cFPUStatusFlag = 0x3F; aContext->uc_mcontext.fpregs->sw &= ~cFPUStatusFlag; ... 0x3F is negated to put 0 in the 6 bits of the status register of the FPU (x87). Doing this implies to check for FPE exceptions after calculation.

• I can't change a value, for a web service using an axiom client!

  - by adrian7

  Hi.I just started learning about web serices. I succesfuly installed Tomcat, and deployed axis2 on it. I followed the tutorial from here http://ws.apache.org/axis2/1_1_1/quickstartguide.html . I made the StockQuoteService web service, moved the .aar file in the WEB-INF/services folder and tested it - it worked all fine. Then I made a client for the servce. I took the source code of the file AXIOMClient.java from the dir described here http://ws.apache.org/axis2/1_1_1/quickstartguide.html#clientaxiom , imported the classes in Eclipse Java IDE and runned it. I tested and the update method works from the browser when calling http://localhost:8080/axis2/services/StockQuoteService/update?symbol=WSO&price=144 But from my java client update method is not working at all, when calling getPrice I always receive 42.00. What am I doing wrong? or, how can I trace what is happening?
