  • bind 2 exe into one

    - by Oghenero
    Hello, i want to bind two exe files into one exe file, and when executed it should only create 1 process. For example you can try to bind windows calc.exe and notepad.exe to binded.exe and when executed it should just see binded.exe in process list and both calc.exe and notepad.exe should start.

  • Get sum of two columns in one LINQ query

    - by Axarydax
    Hi, let's say that I have a table called Items (ID int, Done int, Total int) I can do it by two queries: int total = m.Items.Sum(p=>p.Total) int done = m.Items.Sum(p=>p.Done) But I'd like to do it in one query, something like this: var x = from p in m.Items select new { Sum(p.Total), Sum(p.Done)}; Surely there is a way to call aggregate functions from LINQ syntax...?

  • Total stack sizes of threads in one process

    - by David
    I use pthreads_attr_getthreadsizes() to get default stack size of one thread, 8MB on my machine. But when I create 8 threads and allocate a very large stack size to them, say hundreds of MB, the program crash. So, I guess, shall ("Number of threads" x "stack size of per thread") shall less than a value(virtual memory size)?

  • One entityManger finds entity , the other does not.

    - by Pitelk
    Hi all, I have a very strange behavior in my program. I have 2 classes (class LogIn and CreateGame) where i have injected an EntityManager in each using the annotation @PersistenceContext(unitName="myUnitPU") EntityManager entitymanger; In some point i remove an object called "user" from the database using entitymanger.remove(user) from a method in LogIn class. The business logic is that a user can host and join games ( in the same time) so removing the user all the entries in database about the games the user has created are removed and all the entries showing in which games the user has joined are removed also. After that, i call another function which checks if the user exists using a method in the LogIn class entitymanager.find(user) which surprisingly enough, finds the user. After that I call a method in CreateGame class which tries to find the user by using again entitymanger.find(user) the entitymanger in that class fails to find the user (which is the expected result as the user is removed and it's not in the database) So the question is : Why the entitymanager in one class finds the user (which is wrong) where the other doesn't find it? Does anyone has ever the same problem? PS : This "bug" occurs when the user has hosted a game which is joined by another user (lets call him Buser) and the Buser has made a game which is joined by the current user. GAME | HOST | CLIENTS game1 | user | userB game2 | userB | user where in this case by removing the user, the game1 is deleted and the user is removed from game2 so the result is GAME | HOST | CLIENTS game2 | userB | PS2 : The Beans are EJB3.0. The methods are called from a delegate class. The beans in the delegate class are instantiated using the InitialContext.lookup() method. Note that for logging in ,creating , joining games the appropriate delegate class calls the correspondent EJB which does the transactions. In the case of logOut, the delegate calls an EJB to logout the user but becuase other stuff must be done (as said above) this EJB calls other EJB (again using lookup() ) which has methods like removegame(), removeUserFromGame() etc. After those methods are executed the user is then logged out. Maybe it has something to do with the fact the the first entity manager is called by a delegate but the second from inside an EJb and thats why the one entitymanger can see the non-existent user while the other cannot? Also all the methods have TRANSACTIONTYPE.REQUIRED Thank you in advance

  • WCF (REST) multiple host headers with one endpoint

    - by Maan
    I have an issue with a WCF REST service (.NET 4) which has multiple host headers, but one end point. The host headers are for example: xxx.yyy.net xxx.yyy.com Both host headers are configured in IIS over HTTPS and redirect to the same WCF service endpoint. I have an Error Handling behavior which logs some extra information in case of an error. The problem is that the logging behavior only works for one of both URLs. When I first call the .net URL, the logging is only working for requests on the .net URL. When I first call the .com URL (after a Worker Process recycle), it’s only working on requests on the .com URL. The configuration looks like this: <system.serviceModel> <serviceHostingEnvironment aspNetCompatibilityEnabled="true"/> <services> <service name="XXX.RemoteHostService"> <endpoint address="" behaviorConfiguration="RemoteHostEndPointBehavior" binding="webHttpBinding" bindingConfiguration="HTTPSTransport" contract="XXX.IRemoteHostService" /> </service> </services> <extensions> <behaviorExtensions> <add name="errorHandling" type="XXX.ErrorHandling.ErrorHandlerBehavior, XXX.Services, Version=1.0.0.0, Culture=neutral, PublicKeyToken=null" /> </behaviorExtensions> </extensions> <bindings> <webHttpBinding> <binding name="HTTPSTransport"> <security mode="Transport"> <transport clientCredentialType="None"/> </security> </binding> </webHttpBinding> </bindings> <behaviors> <endpointBehaviors> <behavior name="RemoteHostEndPointBehavior"> <webHttp /> <errorHandling /> </behavior> </endpointBehaviors> </behaviors> …. Should I configure multiple endpoints? Or in which way could I configure the WCF Service so the logging behavior is working for both URLs? I tried several things, also solutions mentioned earlier on StackOverflow. But no luck until now...

  • vb.net one dimensional string array manipulation difficulty

    - by Luay
    Hi, I am having some problems with manipulating a one dimensional string array in vb.net and would like your assistance please. My objective is to get 4 variables (if possible) from a file path. these variables are: myCountry, myCity, myStreet, Filename. All declared as string. The file location is also declared as string. so I have: Dim filePath As String to illustrate my problem and what I am trying to do I have the following examples: 1- C:\my\location\is\UK\Birmingham\Summer Road\this house.txt. In this example myCountry would be= UK. myCity= Birmingham. myStreet=Summer Road. Filename=this house.txt 2- C:\my Location\is\France\Lyon\that house.txt. here myCountry=France. myCity=Lyon. There is no street. Filename=that house.txt 3- C:\my Location is\Germany\the other house.txt Here myCountry=Germany. No city. No street. Filename=the other house.txt What I am trying to say is I have no idea before hand about the lenght of the string or the position of the variables I want. I also don't know if I am going to find/get a city or street name in the path. However I do now that i will get myCountry and it will be one of 5 options: UK, France, Germany, Spain, Italy. To tackle my problem, the first thing I did was Dim pathArr() As String = filePath.Split("\") to get the FileName I did: FileName = pathArr.Last To get myCountry I did: If filePath.Contains("UK") Then myCountry = "UK" ElseIf filePath.Contains("France") Then myCountry = "France" ElseIf filePath.Contains("Germany") Then myCountry = "Germany" ElseIf filePath.Contains("Spain") Then myCountry = "Spain" ElseIf filePath.Contains("Italy") Then myCountry = "Italy" End If in trying to figure out myCity and myStreet (and whether they exist in the string in the first place) I started with: Dim ind As Integer = Array.IndexOf(pathArr, myCountry) to get the index of the myCountry string. I thought I could make my way from there but I am stuck and don't know what to do next. Any help will be appreciated. Thanks

  • objective-c iphone XML parsing one element

    - by Marko
    I know that when parsing XML with objective-c most of the time you use NSXMLParser. But what if you only need to read one element. Using NSXMLParser sounds like an overload to me. The issue is that flickr API doesn't use JSON as response when uploading an image. So my response now is: 4638598522 I only need to know the photoid and I like to know what the best solution will be for this.

  • MySQL, if a value is in one of two columns, return the value from the other one

    - by erikric
    Hi, This might be an easy one, but I'm not really experienced with sql. I have a table with two user_id columns, user1 and user2. This table contains some compared values between the two users. I want to send in an user id, and return all the id's from the other user when the sent user is either user1 or user2. I guess some sort of if test would do the trick, but I don't know how to do this in SQL. Cheers

  • Django: Only one of two fields can be filled in

    - by Giovanni Di Milia
    I have this model: class Journals(models.Model): jid = models.AutoField(primary_key=True) code = models.CharField("Code", max_length=50) name = models.CharField("Name", max_length=2000) publisher = models.CharField("Publisher", max_length=2000) price_euro = models.CharField("Euro", max_length=2000) price_dollars = models.CharField("Dollars", max_length=2000) Is there a way to let people fill out either price_euro or price_dollars? I do know that the best way to solve the problem is to have only one field and another table that specify the currency, but I have constraints and I cannot modify the DB. Thanks!

  • Grails + Spring Security one field login

    - by Miguel
    Hi all Is it possible, using spring security plugin 0.5.3 with Grails 1.2.1, to authenticate a user using only one field? I mean, for example, making j_username and j_password fields in the authentication form equal previous to the authentication. I read it was possible to define j_username field in Config.groovy with acegi plugin, in older versions of the plugin. Now it uses SecurityConfig.groovy but the possibility of defining the field exists no more. Any ideas?? Thanks a lot, Miguel

  • Correct order of overrides for a composite control based on an abstract one

    - by mattdwen
    I'm writing a set of C# composite web server controls for displaying dialog boxes. I want to have one abstract class which handles the basic layout and things like titles of the control, then have a set of derived ones which render child controls at a specific point. I forsee three distincts methods: renderOpeningHtml handled by the abstract class, renderCustomControls as done by the derived class, and renderClosingHtml by the abstract class again, except I can't figure the life cycle of a CompositeControl and what methods to use when.
