• whats a sure shot way to make sure objects appear correctly positioned on stage

  - by dubbeat

  Hi, I've being having a lot of trouble recently getting objects (UIComponents containing movieclips) to appear correctly in the right positions. For example, my current dilema is I have a container that is 3 layers deep. outer layer inner layer display layer This hiearachy was built in CS4 as a movieclip. In the display layer in CS4 I figured out where I want to place 16 different "box" movieclips. I dont want to create these boxes maunually at design time, instead I want to add them at run time. So I know what container I want to add my boxes to. I know what positions they "would" be at in CS4 environment. Whats the best way to add them in the correct locations with code? The "box" I'm trying to add in a movieclip held inside of a UIComponent. Is there a "rule of thumb" to do this type of thing? I'm sure I'm going to encounter this problem again and again and I'd like to just blow the problem out of the water once and for all with the "right way" to do this.

• Which way to go in Linux 3D programming?

  - by Tek

  I'm looking for some answers for a project I'm thinking of. I've searched and from what I understand (correct me if I'm wrong) the only way the program I want to make will work is through 3D application. Let me explain. I plan to make a studio production program but it's unique in the fact that I want to be able to make it fluid. Let me explain. Imagine Microsoft's Surface program where you're able to touch and drag pictures across the screen. Instead of pictures I want them to be sound samples (wavs,mp3,etc). Of course instead the input will be with the mouse but if I ever do finish the project I would totally add touch screen input compatibility! Anyway, I'm guessing there's "physics" to do with it which is why I'm thinking that even though it'll be a 2D application I'll need to code it in a 3D environment. Assuming that I'm correct in how I want to approach my project, where can I start learning about 3D programming? I actually come from PHP programming which will make C++ easier for me to learn. But I don't even know where to start. If I'm not wrong OpenGL is the most up to date API as far as I know. Anyway, please give me your insights guys. I could really use some guidance here since I could totally be wrong in everything that I wrote :)

• how to seamlessly integrate subversion and git?

  - by mattv

  I'm looking for tips on how to seamlessly integrate subversion and git, for deploying web sites by a small team of web developers. We each have our own development versions of our sites on our local machines. We also have dev, staging, and live servers. As our team has grown, we haven't updated our revision control and deployment strategies accordingly. We had all been checking into the trunk of a shared Subversion repository. Both the dev & staging servers ran from a checkout of the trunk, so updating them involved running "svn update" while the live server ran as an export from trunk which required an "svn export" to get the latest code. In either case, we would often update just certain files by updating or exporting just those files or directories. That worked okay when there was just one or two developers. However, a big downside was that we couldn't point to an individual tag that represented what was currently on live at any given time. In keeping with corporate policy, we'd like to continue to use Subversion to store what we're now calling our "production branch," which will be what goes onto staging and live. However, we would like to use Git on our local and development sites. We especially like the idea of easier merges and being able to "cherry pick" updates that need to go live. We had initially planned on using git-svn, but it doesn't seem to work well in a shared environment such as our dev or staging servers. Anyone else doing something like this? What's the best way to make it work? Or are we making it more difficult than it should be?

• JPA / Hibernate checks conditions in merge()

  - by bert

  Working with JPA / Hibernate in an OSIV Web environment is driving me mad ;) Following scenario: I have an entity A that is loaded via JPA and has a collection of B entities. Those B entities have a required field. When the user adds a new B to A by pressing a link in the webapp, that required field is not set (since there is no sensible default value). Upon the next http request, the OSIV filter tries to merge the A entity, but this fails as Hibernate complains that the new B has a required field is not set. javax.persistence.PersistenceException: org.hibernate.PropertyValueException: not-null property references a null or transient value Reading the JPA spec, i see no sign that those checks are required in the merge phase (i have no transaction active) I can't keep the collection of B's outside of A and only add them to A when the user presses 'save' (aka entitymanager.persist()) as the place where the save button is does not know about the B's, only about A. Also A and B are only examples, i have similar stuff all over the place .. Any ideas? Do other JPA implementaions behave the same here? Thanks in advance.

• Blocking HTML and Javascript from being displayed on my site

  - by Tim Powell

  I am working on this new social networking site. One of it's various functions is posting. You can post to Facebook and my site, or Twitter and my site. That being said, I couldn't help but try and post HTML as I was testing sql injection. When I did, I noticed that there where ways to manipulate the site to, for instance, using a element to completely screw up the CSS design, or redirect a user to another site using javascript. That being said, I want to make my site a safe environment for my users... not a site that is used to distribute computer viruses, porn, and other things that might make someone tend to stay off of my site. When I searched this topic, I found ways to "strip" the HTML out of the $post variable before submitting it to the database. However, I would just like to make it so you can post any text, including HTML and Javascript, without the browser interpreting it as "run this..." code: I want to display it as plane text. I've seen it on Facebook, and when I looked at it the source code of a post, it showed <, /, and as regular text. I tried "dissecting" Facebook's source code, but found nothing. I have tried using tags such as <pre> and <code>, but because of the lack of ability to style and control them, I gave up and went back to just allowing HTML. Please, anyone who knows how to do this, please help me out. Thanks in advance, TP

• Is there unresizable space in latex? Pictures in good looking grid.

  - by drasto

  I've created latex macro to typeset guitar chords diagrams(using picture environment). Now I want to make diagrams of different appear in good looking grid when typeset one next to each other as the picture shows: The picture. (on the picture: Labeled "First" bad layout of diagrams, labeled "Second" correct layout when equal number of diagrams in line) I'm using \hspace to make some skips between diagrams, otherwise they would be too near to each other. As you can see in second case when latex arrange pictures in so that there is same number of them in each line it works. However if there is less pictures in the last line they become "shifted" to the right. I don't want this. I guess is because latex makes the space between diagrams in first line a little longer for the line to exactly fit the page width. How do I tell latex not to resize spaces created by \hspace ? Or is there any other way ? I guess I cannot use tables because I don't know how many diagrams will fit in one line... This is current state of code: \newcommand{\spaceForChord}{1.7cm} \newcommnad{\chordChart}[1]{% %calculate dimensions xdim and ydim according to setings \begin{picture}(xdim, ydim){% %draw the diagram inside defined area }% \hspace*{\spaceForChord}% \hspace*{-\xdim}% }% %end preambule and begin document \begin{document} First:\\* \\* \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} \chordChart{...some arguments for to change diagram look...} %...above line is repeated 12 more times to produce result shown at the picture \end{document} Thanks for any help.

• ASP.NET: how can I compile in DEBUG mode?

  - by Budda

  AFAIK, usual ASP.NET web site/web application switched on into DEBUG mode when web/app-config setting "compilation" has debug="false". But I don't clearly understand how it works. Let's consider example: I have <compilation debug="true" />. I've added the following line into "Page_Load" method: System.Diagnostics.Debug.WriteLine("Page_Load"); When I launched web-site in 'debug' mode (using F5 button) It put me 'Page_Load' into output window. Everything is ok so far. When I change application compilation mode into non-debug: Will it recompile everything for 'non-debug' mode? Is this enough to go into "production" environment with this change only? I guess, it should be enough for web-site that doesn't use other project. Otherwise, I would better switch whole configuration into "Release" mode. In this case EACH project will be recompiled in "Release" mode. Am I right? Could you please point me if something is wrong here? Thanks a lot!

• Reflection and Generics get value of property

  - by GigaPr

  Hi i am trying to implement a generic method which allows to output csv file public static void WriteToCsv<T>(List<T> list) where T : new() { const string attachment = "attachment; filename=PersonList.csv"; HttpContext.Current.Response.Clear(); HttpContext.Current.Response.ClearHeaders(); HttpContext.Current.Response.ClearContent(); HttpContext.Current.Response.AddHeader("content-disposition", attachment); HttpContext.Current.Response.ContentType = "text/csv"; HttpContext.Current.Response.AddHeader("Pragma", "public"); bool isFirstRow = true; foreach (T item in list) { //Get public properties PropertyInfo[] propertyInfo = item.GetType().GetProperties(); while (isFirstRow) { WriteColumnName(propertyInfo); isFirstRow = false; } Type type = typeof (T); StringBuilder stringBuilder = new StringBuilder(); foreach (PropertyInfo info in propertyInfo) { //string value ????

• Filtering null values with pig

  - by arianp

  It looks like a silly problem, but I can´t find a way to filter null values from my rows. This is the result when I dump the object geoinfo: DUMP geoinfo; ([longitude#70.95853,latitude#30.9773]) ([longitude#-9.37944507,latitude#38.91780853]) (null) (null) (null) ([longitude#-92.64416,latitude#16.73326]) (null) (null) ([longitude#-9.15199849,latitude#38.71179122]) ([longitude#-9.15210796,latitude#38.71195131]) here is the description DESCRIBE geoinfo; geoinfo: {geoLocation: bytearray} What I'm trying to do is to filter null values like this: geoinfo_no_nulls = FILTER geoinfo BY geoLocation is not null; but the result remains the same. nothing is filtered. I also tried something like this geoinfo_no_nulls = FILTER geoinfo BY geoLocation != 'null'; and I got an error org.apache.pig.backend.executionengine.ExecException: ERROR 1071: Cannot convert a map to a String What am I doing wrong? details, running on ubuntu, hadoop-1.0.3 with pig 0.9.3 pig -version Apache Pig version 0.9.3-SNAPSHOT (rexported) compiled Oct 24 2012, 19:04:03 java version "1.6.0_24" OpenJDK Runtime Environment (IcedTea6 1.11.4) (6b24-1.11.4-1ubuntu0.12.04.1) OpenJDK 64-Bit Server VM (build 20.0-b12, mixed mode)

• User switching without logging off

  - by mrh1967

  We need to switch users without logging off so we can remotely administrate a PC running with a limited user that will disconnect from the VPN if the user logs off. I've got this working by killing the explorer process and then running explorer.exe with the administrator user credentials as the following code shows: private void btnOk_Click(object sender, EventArgs e) { IntPtr tokenHandle = new IntPtr(0); if (LogonUser("administrator", Environment.UserDomainName, txtPassword.Text, 3, 0, ref tokenHandle)) { ProcessStartInfo psi = new ProcessStartInfo(@"C:\Windows\explorer.exe"); psi.UserName = "administrator"; char[] pword = txtPassword.Text.ToCharArray(); psi.Password = new System.Security.SecureString(); foreach (char c in pword) { psi.Password.AppendChar(c); } psi.UseShellExecute = false; psi.LoadUserProfile = true; restartExplorer(psi); this.Close(); } else { MessageBox.Show("Wrong password", "Error", MessageBoxButtons.OK, MessageBoxIcon.Exclamation); } } private void restartExplorer(ProcessStartInfo psi) { Process[] procs = System.Diagnostics.Process.GetProcesses(); foreach (Process p in procs) { if (p.ProcessName == "explorer") { p.Kill(); break; } } System.Diagnostics.Process.Start(psi); } [DllImport("advapi32.dll", SetLastError = true)] public extern static bool LogonUser(String lpszUsername, String lpszDomain, String lpszPassword, int dwLogonType, int dwLogonProvider, ref IntPtr phToken); This code and similar code that does the same but makes the ProcessStartInfo for the limited user works perfectly and allows changing between the limited and administrator accounts without disconnecting the VPN but it has one problem - If we use this to change to the administrator user, make some changes to the system, then change back to the limited user all works ok until the limited user logs off when a blank desktop is displayed until CTRL-ALT-DEL is pressed and the user is logged off again. Because we block CTRL-ALT-DEL the PC effectively hangs until it is powered off. Does anyone know how to stop this from happening so we can change users without the PC hanging when they log off?

• Reload mod_fcgid without killing Python Service

  - by Tobias

  Hi I'm currently running a Django project on my school's webserver with FCGI. I did follow the multiple guides that recommends installing a virtual local Python environment and it worked out great. The only issue i had was that "touching" my fcgi-file to reload source-files wasn't enough, but instead i had to kill the python service via SSH. This because mod_fcgid is used. However, the admin didn't think it was a great idea that i ran my own local python. He thought it better if i just told him what modules to install on root, which was a pretty nice service really. But doing this, i can no longer kill python since it's under root(though immoral as I am, I've definitely tried). The admins recommendation was that I should try too make the fcgi script reload itself by checking time stamp. I've tried to find documentation on how to do this, but fund very little and since I'm a absolute beginner i have no idea what would work. Anyone have experience running python/django under mod_fcgid or tips on where to find related guides/documentation?

• Is the Subversion 'stack' a realistic alternative to Team Foundation Server?

  - by Robert S.

  I'm evaluating Microsoft Team Foundation Server for my customer, who currently uses Visual SourceSafe and nothing else. They have explicitly expressed a desire to implement a more rigid and process-driven environment as their application is in production and they have future releases to consider. The particular areas I'm trying to cover are: Configuration management (e.g., source control) Change management (workflow and doco for change requests, tasks) Release management (builds and deployments) Incident and problem management (issues and bugs) Document management (similar to source control, but available via web) Code analysis constraints on check-ins A testing framework Reporting Visual Studio 2008 integration TFS does all of these things quite well, but it's expensive and complex to maintain, and the inexpensive Workgroup edition doesn't scale. We don't get TFS as part of our MSDN subscription. Those problems can be overcome, but before I tell my customer to go the TFS route, which in itself isn't a terrible thing, I wanted to evaluate the alternatives. I know Subversion is often suggested for its configuration management/source control, but what about the other areas? Would a combination of Subversion/NUnit/Wiki/CruiseControl/NAnt/something else satisfy all of these requirements? What tools do I need to include in my evaluation? Or should I just bite the bullet and go with TFS since we're already invested in the Microsoft stack?

• What rules govern cross-version compatibility for .NET applications and the C# language?

  - by John Feminella

  For some reason I've always had trouble remembering the backwards/forwards compatibility guarantees made by the framework, so I'd like to put that to bed forever. Suppose I have two assemblies, A and B. A is older and references .NET 2.0 assemblies; B references .NET 3.5 assemblies. I have the source for A and B, Ax and Bx, respectively; they are written in C# at the 2.0 and 3.0 language levels. (That is, Ax uses no features that were introduced later than C# 2.0; likewise Bx uses no features that were introduced later than 3.0.) I have two environments, C and D. C has the .NET 2.0 framework installed; D has the .NET 3.5 framework installed. Now, which of the following can/can't I do? Running: run A on C? run A on D? run B on C? run C on D? Compiling: compile Ax on C? compile Ax on D? compile Bx on C? compile Bx on D? Rewriting: rewrite Ax to use features from the C# 3 language level, and compile it on D, while having it still work on C? rewrite Bx to use features from the C# 4 language level on another environment E that has .NET 4, while having it still work on D?' Referencing from another assembly: reference B from A and have a client app on C use it? reference B from A and have a client app on D use it? reference A from B and have a client app on C use it? reference A from B and have a client app on D use it? More importantly, what rules govern the truth or falsity of these hypothetical scenarios?

• Time out when creating a site collection

  - by Daeko

  I am trying to create a site collection programmatically. It has worked for about 6 months, but after the servers have been updated (various patches) it doesn’t work anymore (we have 3 servers: 1 development, 1 test, 1 production). It is still working in my development environment which hasn’t been updated, but not on the two others. I don’t receive any error messages, it just hangs at the code that is supposed to add the site collection (see code below). I am using Windows Server 2003 R2 and Sharepoint 2007 (version 12.0.0.6421 ). It doesn’t give me any errors, it just hangs until Internet Explorer comes with a “request timed out” response. If I try and debug the code, the code just stops there and nothing happens. No error messages or anything. public static string CreateSPAccountSite(string siteName) { string url = ""; SPSecurity.RunWithElevatedPrivileges(delegate() { SPWeb web = SPContext.Current.Web; using (SPSite siteCollectionOuter = new SPSite(web.Site.ID)) { SPWebApplication webApp = siteCollectionOuter.WebApplication; SPSiteCollection siteCollection = webApp.Sites; SPSite site = siteCollection.Add("sites/" + siteName, siteName, "Auto generated Site collection.", 1033, "STS#0", siteCollectionOuter.Owner.LoginName, siteCollectionOuter.Owner.Name, siteCollectionOuter.Owner.Email); //Hangs here site.PortalName = "Portal"; site.PortalUrl = mainUrl; // https://www.ourdomain.net url = site.Url; } }); return url; //Should be "https://www.outdomain.net/sites/siteName" }

• Help me convert .NET 1.1 Xml validation code to .NET 2.0 please.

  - by Hamish Grubijan

  It would be fantastic if you could help me rid of these warnings below. I have not been able to find a good document. Since the warnings are concentrated in just the private void ValidateConfiguration( XmlNode section ) section, hopefully this is not terribly hard to answer, if you have encountered this before. Thanks!

• Help me find article on Multi-threading and Event Handling in Java

  - by JDR

  I once read an article on how to properly write event handlers for multi-threading in Java, but I can't for the life of me find it anymore. It described the pitfalls and potentials for deadlocks that can occur when firing events (not Swing events mind you, but general events like model update notifications). To clarify, the situation would be as such: // let's say this is code from an MVC model somewhere public void setSomeProperty(String myProperty){ if(!this.myProperty.equals(myProperty)){ this.myProperty = myProperty; fireMyPropertyChangedEvent(...); } } The article described how passing control to arbitrary external listener code was a potential cause for deadlock. I now find myself in a situation where I need to fire such events in a multithreaded environment and I would very much like to read the article again to see what it has to say before I continue. Does anyone know the article I'm referring to? I believe it came as a (fairly short) PDF. It started off with an initial naive implementation and incrementally pointed out flaws and improved upon it. It ended with a sort of final proper-way-to-fire-multithreaded-events. I've searched endlessly in my browse history and on google, but all I could find were endless amounts topics on Swing event dispatch threads. Thank you.

• How to avoid concurrent execution of a time-consuming task without blocking?

  - by Diego V

  I want to efficiently avoid concurrent execution of a time-consuming task in a heavily multi-threaded environment without making threads wait for a lock when another thread is already running the task. Instead, in that scenario, I want them to gracefully fail (i.e. skip its attempt to execute the task) as fast as possible. To illustrate the idea considerer this unsafe (has race condition!) code: private static boolean running = false; public void launchExpensiveTask() { if (running) return; // Do nothing running = true; try { runExpensiveTask(); } finally { running = false; } } I though about using a variation of Double-Checked Locking (consider that running is a primitive 32-bit field, hence atomic, it could work fine even for Java below 5 without the need of volatile). It could look like this: private static boolean running = false; public void launchExpensiveTask() { if (running) return; // Do nothing synchronized (ThisClass.class) { if (running) return; running = true; try { runExpensiveTask(); } finally { running = false; } } } Maybe I should also use a local copy of the field as well (not sure now, please tell me). But then I realized that anyway I will end with an inner synchronization block, that still could hold a thread with the right timing at monitor entrance until the original executor leaves the critical section (I know the odds usually are minimal but in this case we are thinking in several threads competing for this long-running resource). So, could you think in a better approach?

• How to query an .NET assembly's required framework (not CLR) version?

  - by Bonfire Burns

  Hi, we are using some kind of plug-in architecture in one of our products (based on .NET). We have to consider our customers or even 3rd party devs writing plug-ins for the product. The plug-ins will be .NET assemblies that are loaded by our product at run-time. We have no control about the quality or capabilities of the external plug-ins (apart from checking whether they implement the correct interfaces). So we need to implement some kind of safety check while loading the plug-ins to make sure that our product (and the hosting environment) can actually host the plug-in or deliver a meaningful error message ("The plug-in your are loading needs .NET version 42.42 - the hosting system is only on version 33.33."). Ideally the plug-ins would do this check internally, but our experience regarding their competence is so-so and in any case our product will get the blame, so we want to make sure that this "just works". Requiring the plug-in developers to provide the info in the metadata or to explicitly provide the information in the interface is considered "too complicated". I know about the Assembly.ImageRuntimeVersion property. But to my knowledge this tells me only the needed CLR version, not the framework version. And I don't want to check all of the assembly's dependencies and match them against a table of "framework version vs. available assemblies". Do you have any ideas how to solve this in a simple and maintainable fashion? Thanks & regards, Bon

• Phonegap: Will my mobile app 'feel' faster or slower once ported to phonegap?

  - by user15872

  So I'm designing everything in mobile Safari and I know that phonegap is essentially a stripped webview but... Question: Will my application will run better in phonegap? (revised below) a)I imagine my navigation and core app will load faster as the scripts and images are on the hard drive. Is this True? b)I assume since they've been working on it for 2 years now that they may have made some optimizations to make it quicker than just an average safari window. Is this true? (Assuming both html5/js/css code bases are pretty much the same and app is running on iOS.) Update: Sorry, I meant to compare apples to slightly different apples. Question 1 revised: Will my app see any performance benefits running with in a phonegap environment vs standard mobile safari? (compare mobile - to mobile) 1b) In what ways, other than loading time has phonegap optimized performance over standard mobile safari? Follow ups: 1) Are there any pitfalls, other than large libraries, that may cause phonegap to suffer a serious performance hit vs stand mobile safari? 2) Can I mix native and webview rendering? (i.e the top half of my app is rendered in with html/css/js and the bottom half native)

• Determine asymmetric latencies in a network

  - by BeeOnRope

  Imagine you have many clustered servers, across many hosts, in a heterogeneous network environment, such that the connections between servers may have wildly varying latencies and bandwidth. You want to build a map of the connections between servers my transferring data between them. Of course, this map may become stale over time as the network topology changes - but lets ignore those complexities for now and assume the network is relatively static. Given the latencies between nodes in this host graph, calculating the bandwidth is a relative simply timing exercise. I'm having more difficulty with the latencies - however. To get round-trip time, it is a simple matter of timing a return-trip ping from the local host to a remote host - both timing events (start, stop) occur on the local host. What if I want one-way times under the assumption that the latency is not equal in both directions? Assuming that the clocks on the various hosts are not precisely synchronized (at least that their error is of the the same magnitude as the latencies involved) - how can I calculate the one-way latency? In a related question - is this asymmetric latency (where a link is quicker in direction than the other) common in practice? For what reasons/hardware configurations? Certainly I'm aware of asymmetric bandwidth scenarios, especially on last-mile consumer links such as DSL and Cable, but I'm not so sure about latency. Added: After considering the comment below, the second portion of the question is probably better off on serverfault.

• SELECT Statement without duplicate rows on the multiple join tables

  - by theBo

  I have 4 tables built with JOINS and I would like to SELECT DISTINCT rows on the setsTbl.s_id so they always show regardless if there's relational data against them or not!. This is what I have at present which displays the data but doesn't display all of but not the entire distinct row! SELECT setsTbl.s_id, setsTbl.setName, userProfilesTbl.no + ' ' + userProfilesTbl.surname AS Name, trainingTbl.t_date, userAssessmentTbl.o_id FROM userProfilesTbl LEFT OUTER JOIN userAssessmentTbl ON userProfilesTbl.UserId = userAssessmentTbl.UserId FULL OUTER JOIN trainingTbl ON userAssessmentTbl.tt_id = trainingTbl.tt_id RIGHT OUTER JOIN setsTbl ON trainingTbl.s_id = setsTbl.s_id WHERE (userProfilesTbl.st_id=@st_id AND userProfilesTbl.sh_id=@sh_id) AND (DATEPART(yyyy,t_date) = @y_date ) OR (userAssessmentTbl.o_id IS NULL) ORDER BY setName ASC, t_date ASC With this statement I get some of the rows (the ones with data against them) but as stated the s_id field does not return distinct.

  Hi. My Procedure last day as below Click Start, Run and type Regedit.exe Navigate to the following branch: HKEY_CURRENT_USER \ Software \ Microsoft \ Command Processor In the right-pane, double-click Autorun and set the startup folder path as its data, preceded by “CD /d “. If Autorun value is missing, you need to create one, of type REG_EXPAND_SZ or REG_SZ in the above location. Example: To set the startup directory to D:\learning\perl, set the Autorun value data to CD /d D:\learning\perl Then I clicked Start, run and type cmd. It successfully. I could do perl practice more conveniently now. But today, I find when I try to build my Visual Studio 2005 solution which included some Pre-build event Command like this: perl.exe MyAppVersion.pl perl.exe AttrScan.pl It doesn't work. Show error: can't find the path. I check the environment variable setting and find the variable-path and it's value-c:\perl\bin\; still exist. Finially, I try to removed the Regedit.exe configuration "Autorun" value and test again. The issue fixed. I only changed the default startup directory for cmd.exe command. Why the pre-build event perl command was impacted? (I am using winxp and activePerl 5.8)

• Is it possible to use a serial port like session in c#?

  - by Pandiya Chendur

  I am using serial port communication in my asp.net webform application... private bool sendSMS(int portNo, string mobNo, string details) { try { SerialPort SerialPort1 = new SerialPort(); SerialPort1.PortName = "COM" + portNo.ToString(); SerialPort1.BaudRate = 9600; SerialPort1.Parity = Parity.None; SerialPort1.DataBits = 8; SerialPort1.StopBits = StopBits.One; SerialPort1.RtsEnable = true; SerialPort1.DtrEnable = true; SerialPort1.Encoding.GetEncoder(); SerialPort1.ReceivedBytesThreshold = 1; SerialPort1.NewLine = Environment.NewLine; SerialPort1.Open(); SerialPort1.Write("AT" + SerialPort1.NewLine); Sleep(500); SerialPort1.Write("AT+CMGF=1" + SerialPort1.NewLine); Sleep(500); SerialPort1.Write("AT+CMGS=" + (char)34 + mobNo + (char)34 + SerialPort1.NewLine); Sleep(1000); SerialPort1.Write(details + (char)26); Sleep(2000); SerialPort1.Close(); } catch { } return true; } This method works when i send i single message... But when want to send sms in bulk opening and closing port everytime is not a good idea... So my question is it possible to use a serial port like session in c#?... When i open a port i want it to be open for 1 hour and then if my time expires i want to close the port and open it the next time... Any suggestion...

• Anyone Experiencing Slow Builds With VS2010?

  - by MrKWatkins

  Hi, We've recently upgraded to the final release of VS2010 and are experiencing very slow build times compared to the same code under 2008. I was wondering if anyone else is experiencing the same so I can work out whether it's just our environment or not? A few details: Using VS2010 Ultimate on Windows 7 with fairly beefy machines, talking to TFS 2010. The solution has been upgraded from VS2008 but still builds against .NET 3.5 and ASP.NET MVC 1.0. It doesn't seem to be the compilation itself taking long but something else in the build process. This is because even projects that are up to date and don't need compiling are taking a few seconds or so to process. It's not due to an Visual Studio addin because a couple guys in the team haven't installed any. The first build after loading VS2010 is pretty quick, then they seem to slow down over time. For example on of the projects in my solution just took 00:00:00.08 to process after a restart. (The project was up to date and didn't need compiling) I then immediately hit rebuild and it jumps to 00:00:01.33. We're also experiencing the problem with another solution that uses .NET 4.0 that was building perfectly fine under VS2010 RC. There are no build events or anything like that I can blame, just straightforward assembly builds. The IDE is not very responsive during the slow builds. Anyone else has similar problems? Update: It looks like the resolving assembly references is taking a long time. Looking at the MSBuild diagnostic output or the example above the first build has 30ms for ResolveAssemblyReferences, the second build has 800ms. Subsequent builds seem to be taking longer copying stuff around, e.g. CopyFilesToOutputDirectory jumps from 1ms to 27ms.

• Android - Turn off display without triggering sleep/lock screen - Turn on with Touchscreen

  - by NebulaSleuth

  I have been trying to find a way to turn off the display, and wake up from the user touching the touch screen. The device is in an embedded environment where the device is a tablet and the user does not have access to anything except the touch screen (no buttons at all). It is connected to power so the battery won't be a problem, but when I detect no activity I want to turn off the screen so it isn't staring them in the face all day and doesn't reduce the life the LCD backlight. I maintain a wakelock permanently and decide when to sleep myself. The problem is that when I turn off the screen using : WindowManager.LayoutParams params = getWindow().getAttributes(); params.screenBrightness = 0; getWindow().setAttributes(params); The activity gets paused and stopped. And the unit does not respond to a touch to wake it up. You need to press the power button. At that point the "slide to unlock" shows up. I want to turn off the display, and then stay running so I can detect a touch screen event and turn the display back on. I also tried turning the display to a brightness of 0.1, which works on some devices, but the device I need it to work on, only "dims" the display. I also tried this: // First Remove my FULL wakelock //then aquire a partial wake lock (which should turn off the display) PowerManager.WakeLock wl = manager.newWakeLock(PowerManager.PARTIAL_WAKE_LOCK, "Your Tag"); wl.acquire(); however this method does not turn off the display.
