  • .Net with single .exe without .NET Framework installation

    - by user156144
    I wrote my simple desktop program in C#. I am reluctant to distribute it on the internet because i am not sure if users will go through pain of installing the .Net Framework. My target users are non-tech savvy users. I am very familiar with MFC and I probably can write this program in MFC in a month. MFC is nice because I don't have to worry about distributing other components. It will be one nice single executable. So my real question is this: Is it possible to write .Net app without worrying about distributing .Net Framework? Update I found another solution: If you are using Innosetup, there is a script that installs .net framework. http://www.codeproject.com/KB/install/dotnetfx_innosetup_instal.aspx

  • How do I improve the efficiency of the queries executed by this generic Linq-to-SQL data access clas

    - by Lee D
    Hi all, I have a class which provides generic access to LINQ to SQL entities, for example: class LinqProvider<T> //where T is a L2S entity class { DataContext context; public virtual IEnumerable<T> GetAll() { return context.GetTable<T>(); } public virtual T Single(Func<T, bool> condition) { return context.GetTable<T>().SingleOrDefault(condition); } } From the front end, both of these methods appear to work as you would expect. However, when I run a trace in SQL profiler, the Single method is executing what amounts to a SELECT * FROM [Table], and then returning the single entity that meets the given condition. Obviously this is inefficient, and is being caused by GetTable() returning all rows. My question is, how do I get the query executed by the Single() method to take the form SELECT * FROM [Table] WHERE [condition], rather than selecting all rows then filtering out all but one? Is it possible in this context? Any help appreciated, Lee

  • RijndaelManaged Padding when data matches block size

    - by trampster
    If I use PKCS7 padding in RijndaelManaged with 16 bytes of data then I get 32 bytes of data output. It appears that for PKCS7 when the data size matches the block size it adds a whole extra block of data. If I use Zeros padding for 16 bytes of data I get out 16 bytes of data. So for Zeros padding if the data matches the block size then it doesn't pad. I have searched through the documentation and it says nothing about this difference in padding behavior. Can someone please point me to some kind of documentation which specifies what the padding behavior should be for the different padding modes when the data size matches the block size.

  • File Locked by Services (after service code reading the text file)

    - by rvpals
    I have a windows services written in C# .NET. The service is running on a internal timer, every time the interval hits, it will go and try to read this log file into a String. My issue is every time the log file is read, the service seem to lock the log file. The lock on that log file will continue until I stop the windows service. At the same time the service is checking the log file, the same log file needs to be continuously updated by another program. If the file lock is on, the other program could not update the log file. Here is the code I use to read the text log file. private string ReadtextFile(string filename) { string res = ""; try { System.IO.FileStream fs = new System.IO.FileStream(filename, System.IO.FileMode.Open, System.IO.FileAccess.Read); System.IO.StreamReader sr = new System.IO.StreamReader(fs); res = sr.ReadToEnd(); sr.Close(); fs.Close(); } catch (System.Exception ex) { HandleEx(ex); } return res; } Thank you.

  • License similar to the MIT license but without the ability to sell?

    - by Ben
    I'm trying to decide how I want to license my Wordpress themes to the public. I know that the GPL is recommended to Wordpress theme creators, however I feel it might not be liberal enough for me because I want businesses to be able to use them if they want to. I really like the MIT license, the only thing that gets me is the freedom to sell part. I don't want someone taking my themes and selling them on some theme farm site, they should be free for everyone, however I don't want to require them to republish any changes under the MIT as well, I think that that freedom should remain intact. Is there a license that sort of fits into the terms I specified here? I'm not a lawyer so I have trouble reading through the complicated language of licenses. If there is not a similar license to the MIT but with the terms I have specified, should I just license under a modified MIT? If so, can anyone help me write it? Thanks very much!

  • Embed a JRE in a Windows executable?

    - by perp
    Suppose I want to distribute a Java application. Suppose I want to distribute it as a single executable. I could easily build a .jar with both the application and all its external dependencies in a single file (with some Ant hacking). Now suppose I want to distribute it as an .exe file on Windows. That's easy enough, given the nice tools out there (such as Launch4j and the likes). But suppose now that I also don't want to depend on the end user having the right JRE (or any JRE at all for that matter) installed. I want to distribute a JRE with my app, and my app should run on this JRE. It's easy enough to create a Windows installer executable, and embed a folder with all necessary JRE files in it. But then I'm distributing an installer and not a single-file app. Is there a way to embed both the application, and a JRE, into an .exe file acting as the application launcher (and not as an installer)?

  • Caching Authentication Data

    - by PartlyCloudy
    Hi, I'm currently implementing a REST web service using CouchDB and RESTlet. The RESTlet layer is mainly for authentication and some minor filtering of the JSON data served by CouchDB: Clients <= HTTP = [ RESTlet <= HTTP = CouchDB ] I'm using CouchDB also to store user login data, because I don't want to add an additional database server for that purpose. Thus, each request to my service causes two CouchDB requests conducted by RESTlet (auth data + "real" request). In order to keep the service as efficent as possible, I want to reduce the number of requests, in this case redundant requests for login data. My idea now is to provide a cache (i.e.LRU-Cache via LinkedHashMap) within my RESTlet application that caches login data, because HTTP caching will probabily not be enough. But how do I invalidate the cache data, once a user changes the password, for instance. Thanks to REST, the application might run on several servers in parallel, and I don't want to create a central instance just to cache login data. Currently, I save requested auth data in the cache and try to auth new requests by using them. If a authentication fails or there is now entry available, I'll dispatch a GET request to my CouchDB storage in order to obtain the actual auth data. So in a worst case, users that have changed their data will perhaps still be able to login with their old credentials. How can I deal with that? Or what is a good strategy to keep the cache(s) up-to-date in general? Thanks in advance.

  • Distributing a bundle of files across an extranet

    - by John Zwinck
    I want to be able to distribute bundles of files, about 500 MB per bundle, to all machines on a corporate "extranet" (which is basically a few LANs connected using various private mechanisms, including leased lines and VPN). The total number of hosts is roughly 100, and the goal is to get a copy of the bundle from one host onto all the other hosts reliably, quickly, and efficiently. One important issue is that some hosts are grouped together on single fast LANs in which case the network I/O should be done once from one group to the next and then within each group between all the peers. This is as opposed to a strict central server system where multiple hosts might each fetch the same bundle over a slow link, rather than once via the slow link and then between each other quickly. A new bundle will be produced every few days, and occasionally old bundles will be deleted (but that problem can be solved separately). The machines in question happen to run recent Linuxes, but bonus points will go to solutions which are at least somewhat cross-platform (in which case the bundle might differ per platform but maybe the same mechanism can be used). That's pretty much it. I'm not opposed to writing some code to handle this, but it would be preferable if it were one of bash, Python, Ruby, Lua, C, or C++.

  • AIR: sync gui with data-base?

    - by John Isaacks
    I am going to be building an AIR application that shows a list (about 1-25 rows of data) from a data-base. The data-base is on the web. I want the list to be as accurate as possible, meaning as soon as the data-base data changes, the list displayed in the app should update asap. I do not know of anyway that the air application could be notified when there is a change, I am thinking I am going to have to poll the data-base at certain intervals to keep an up to date list. So my question is, first is there any way to NOT have to keep checking the data-base? or if I do keep have to keep checking the data-base what is a reasonable interval to do that at? Thanks.

  • Problems running XNA game on 64-bit Windows 7

    - by Tesserex
    I'm having problems getting my game engine to run on my brother's machine, which is running 64-bit Windows 7. I'm developing on 32-bit XP SP2. My app uses XNA, FMOD.NET, and another dll I wrote entirely in C#. Everything is targeted to x86, not AnyCPU. I've read that this is required for XNA to work because there is no 64-bit xna framework. I recompiled FMOD.NET as x86 as well and made sure to be using the 32-bit version of the native dll. So I don't see any problems there. However when he tries to run my app, it gives an error which is mysterious, but not unheard of. A FileNotFoundException with an empty file name, and the top of the stack trace is in my main form constructor. The message is The specified module could not be found. (Exception from HRESULT: 0x8007007E) I found some threads online about this error, all with very vague, mixed, and fuzzy responses that don't really help me. Most remind people to target x86. Some say check that they have all the dlls necessary. I gave my brother Microsoft.Xna.Framework.dll, but does he need to install the entire XNA redistributable package? When I take everything I sent him and stick it in a random directory, it still runs fine for me. I developed the game in VS2008, not in game studio, using XNA 3.0 and a Windows Forms control that uses XNA drawing which I found in an msdn tutorial. I would also like to avoid requiring a full installer if possible. Any insight? Please?

  • HLSL How can one pass data between shaders / read existing colour value?

    - by RJFalconer
    Hello all, I have 2 HLSL ps2.0 shaders. Simplified, they are: Shader 1 Reads texture Outputs colour value based on this texture Shader 2 Needs to read in existing colour (or have it passed in/read from a register) Outputs the final colour which is a function of the previous colour (They need to be different shaders as I've reached the maximum vertex-shader outputs for 1 shader) My problem is I cannot work out how Shader 2 can access the existing fragment/pixel colour. Is the only way for shaders to interact really just the alpha blending options? These aren't sufficient if I want to use the colour as input to my function.

  • How do I display data in a table and allow users to copy selected data?

    - by cfouche
    Hi I have a long list of data that I want to display in table format to users. The data changes when the user performs certain actions in my app, but it is not directly editable. So the user can create a reasonably big table of data, but he can't change individual cells' values. However, I do want the data to be copy-able. So I want it to be possible for the user to select some or all of the cells, and do a ctrl-C to copy the data to his clipboard, and then a ctrl-V to paste the data to an external text editor. At the moment, I'm displaying the data in a ListView with a GridView and this works perfectly, except that GridView doesn't allow one to copy data. What other options can I try? Ours is a WPF app, coding in c#.

  • Windows Service doesn't start process with different credentials

    - by Marcus
    I have a Windows Service, running as a user, that should start several processes under different user credentials. I'm using the following code to start a process: Dim winProcess As New System.Diagnostics.Process With winProcess .StartInfo.Arguments = "some_args" .StartInfo.CreateNoWindow = True .StartInfo.ErrorDialog = False .StartInfo.FileName = "C:\TEMP\ProcessFromService\ProcessFromService\bin\Debug\ProcessFromService.exe" .StartInfo.UseShellExecute = False .StartInfo.WindowStyle = ProcessWindowStyle.Hidden 'Opgave WorkingDirectory kan soms tot problemen leiden, indien betreffende directory 'niet bereikbaar (rechten) is voor opgegeven gebruiker. 'Beter dus om deze niet op te geven. '.StartInfo.WorkingDirectory = My.Computer.FileSystem.SpecialDirectories.Temp .StartInfo.Domain = "" .StartInfo.UserName = "MyUserId" Dim strPassword As String = "MyPassword" Dim ssPassword As New Security.SecureString For Each chrPassword As Char In strPassword.ToCharArray ssPassword.AppendChar(chrPassword) Next .StartInfo.Password = ssPassword .Start() End With The process is correctly started when I use the same credentials as of which the Windows Service is running under. The process is not started, without any error, when I use different credentials. In other words: If the Windows Service is running as UserA then I can start a process running as UserA. If the Windows Service is running as UserB then I can not start a process running as UserA. I have created a test project in which I can reproduce this problem. If you put this project in C:\Temp then the used paths will be correct. You can download this test project here: https://dl.dropboxusercontent.com/u/5391091/ProcessFromService.zip NB: I hope this info is enough to explain it. If you need more info, please let me know and I will add it.

  • Use queried json data in a function

    - by SztupY
    I have a code similar to this: $.ajax({ success: function(data) { text = ''; for (var i = 0; i< data.length; i++) { text = text + '<a href="#" id="Data_'+ i +'">' + data[i].Name + "</a><br />"; } $("#SomeId").html(text); for (var i = 0; i< data.length; i++) { $("#Data_"+i).click(function() { alert(data[i]); RunFunction(data[i]); return false; }); } } }); This gets an array of some data in json format, then iterates through this array generating a link for each entry. Now I want to add a function for each link that will run a function that does something with this data. The problem is that the data seems to be unavailable after the ajax success function is called (although I thought that they behave like closures). What is the best way to use the queried json data later on? (I think setting it as a global variable would do the job, but I want to avoid that, mainly because this ajax request might be called multiple times) Thanks.

  • wcf class implementing multiple service contracts

    - by Archie
    Hello, I have a class TestService which implements two service contracts called IService1 and IService2. But I'm facing a difficulty in implementation. My Code looks as follows: Uri baseAddress = new Uri("http://localhost:8000/ServiceModel/Service"); Uri baseAddress1 = new Uri("http://localhost:8080/ServiceModel/Service1"); ServiceHost selfHost = new ServiceHost(typeof(TestService)); selfHost.AddServiceEndpoint(typeof(IService1), new WSHttpBinding(), baseAddress); selfHost.AddServiceEndpoint(typeof(IService2), new WSHttpBinding(), baseAddress1); ServiceMetadataBehavior smb = new ServiceMetadataBehavior(); smb.HttpGetEnabled = true; selfHost.Description.Behaviors.Add(smb); selfHost.Open(); Console.WriteLine("The service is ready."); Console.WriteLine("Press <ENTER> to terminate service."); Console.WriteLine(); Console.ReadLine(); selfHost.Close(); I'm getting a run time error as: The HttpGetEnabled property of ServiceMetadataBehavior is set to true and the HttpGetUrl property is a relative address, but there is no http base address. Either supply an http base address or set HttpGetUrl to an absolute address. What shall i do about it? Do I realy need two separate endpoints? Thanks.

  • Can I update an iOS Enterprise App in the background like an App Store app can?

    - by lehn0058
    I have an iOS enterprise app that we are wirelessly distributing to our devices. Currently the app polls our server once a day to see if there is an app update. If there is, we try to install it by having the app call the following code: NSURL *installUrl = [NSURL URLWithString:[NSString stringWithFormat:@"itms-services://?action=download-manifest&url=%@", plistUrl]]; [[UIApplication sharedApplication] openURL:installUrl]; This causes the app to prompt the user with an alert dialog to install the update. If they click install, the app closes and the update is downloaded and installed. I am wondering if there is anything for enterprise apps for iOS 7 similar to the AppStore's automatic updates? I would like to be able to update our app without the user having to press an update button and be able to update at a time when the user won't have to wait for it to install.

  • How to use a data type (table) defined in another database in SQL2k8?

    - by Victor Rodrigues
    I have a Table Type defined in a database. It is used as a table-valued parameter in a stored procedure. I would like to call this procedure from another database, and in order to pass the parameter, I need to reference this defined type. But when I do DECLARE @table dbOtherDatabase.dbo.TypeName , it tells me that The type name 'dbOtherDatabase.dbo.TypeName' contains more than the maximum number of prefixes. The maximum is 1. How could I reference this table type?

  • Separation of static and dynamic content in Java EE applications

    - by Dan
    We work with IBM products and we typically use IBM Http Servers (read Apache) as a reverse proxy for our application servers. For performance reasons we serve static content (.gif, .jpg, .css, .html etc.) from our http servers, to ease the burden a bit from the application server. So far, we have to distribute files to http server and configure it manually (writing custom scripts at best.) The problem is the effort needed to keep everything in synch, especially when you need to update the app. Does any Java EE product support this “out of the box”? Is there a way to have application server do this automatically, like in cluster configuration for example, where master node is in charge of distributing the application to other nodes and for keeping everything in synch.

  • JSmooth question on bundling a JRE

    - by chama
    I'm trying to bundle a JRE with my jar file so that I can run my application on any windows computer, regardless of if it has Java or not. The jsmooth manual says: For the option to work correctly, you have to put a JRE in a directory near the EXE (generally in a subdirectory called "jre" or whatever). Once the exe is generated, it will FIRST try to locate the JRE at the location mentioned. If it can't be found there, then it will fallback in the normal jre look-up mode (search for a jre or a jdk in the Windows registry or in commonly-used environment variables). There is no JVM-version check when using a bundled JRE, as the packager is supposed to bundle a suitable JVM for the application. Does this mean that the jre subfolder should be included in the jar, be its own separate jar, or put in the folder that comes along with the exe? If it is supposed to be in a folder with the exe, how can I specify the relative path to the jre subfolder? My directories are as follows: setup/ -jre/ -myprogram.exe I tried using ..\jre, .\jre, ..\setup\jre in the GUI screen, but none of them worked. Any ideas or leads would be greatly appreciated. Thanks so much! EDIT: when I tried jre (and ..\jre I think), I got the following error message from windows when I tried running it "MyProgram.exe has stopped running." When I look at the problem details, it says APPCRASH and the fault module name is jvm.dll

  • After adding data files to a file group Is there a way to distribute the data into the new files?

    - by Blootac
    I have a database in a single file group, with a single file group. I've added 7 data files to this file group. Is there a way to rebalance the data over the 8 data files other than by telling sql server to empty the original? If this is the only way, is it possible to allow sql server to start writing to this file? MSDN says that once its empty its marked so no new data will be written to it. What I'm aiming for is 8 equally balanced data files. I'm running SQL Server 2005 standard edition. Thanks

  • Using maven to distribute a swing application that can have each dependency individually tracked

    - by tms
    I'm moving my project to Maven and eventually OSGi. I currently distribute the project is a large Zip file with all the dependencies. Although my projects code is only 20% of the total package I have to redistribute all the dependency. With smaller independent modules this may be even less. Looking here on stack overflow it seems that to keep my current plan the maven-assembly-plugin should do the trick. I was considering having a base installer that would look at a XML manifest, then collect all the libraries that needed to be updated. This would mean that libraries that change occasionally would be downloaded less often. This also makes since for something like OSGi plugins (which could have independent release schedules). In essence I want my software to look and manage individual libraries, and download on demand (based on the manifest). I was wondering if there is a "maven way" of generating this Manifest and publishing all the libraries to a website? I believe the deploy life-cycle would do the second step. As an alternative, is there a OpenSource Java library that does this type of deployment? I don't want to embed Maven or something larger with the distributed code. The application is not for coders, the simpler the better, and the smaller the installer the better.

  • I created a Python egg; now what?

    I've finally figured out how to create a Python egg and gotten it to work. What do I do with it now? How do I use it? How do I ensure that everything was correctly included? (Simple steps please... not just redirection to another site. I've googled, but it's confusing me, and I was hoping someone could explain it in a couple of simple bullet points or sentences.)
