  • How do I link one listview to another to create a football league table?

    - by Richard Nixon
    Hi I am creating a football system in windows forms c#. I have one listview where data is entered. I have 4 columns, 2 with team names linked to combo boxes and 2 with the scores linked to numericupdown controls. There are 3 buttons to add the results, Remove and clear. the code is below: private void addButton_Click(object sender, EventArgs e) { { ListViewItem item = new ListViewItem(comboBox1.SelectedItem.ToString()); item.SubItems.Add(numericUpDown1.Value.ToString()); item.SubItems.Add(numericUpDown2.Value.ToString()); item.SubItems.Add(comboBox2.SelectedItem.ToString()); listView1.Items.Add(item); } } private void clearButton_Click(object sender, EventArgs e) { listView1.Items.Clear(); } private void removeButton_Click(object sender, EventArgs e) { foreach (ListViewItem itemSelected in listView1.SelectedItems) { listView1.Items.Remove(itemSelected); } } I have another listview that i want to link the first one to. The second one is a usual english football league table and i want to use maths to add up the games played and the points etc. please help. cheers

  • Generic dataset handling library

    - by Pep.
    Hello, I want to build a generic Perl module for handling and analysing biomedical character separated datasets and which can, most certain, be used on any kind of datasets that contain a mixture of categorical (A,B,C,..) and continuous (1.2,3,881..) and identifier (XXX1,XXX2...). The plan is to have people initialize the module and then use some arguments to point to the data file(s), the place were the analysis reports should be placed and the structure of the data. By structure of data I mean which variable is in which place and its name/type. And this is where I need some enlightenment. I am baffled how to do this in a clean way. Obviously, having people create a simple schema file, be it XML or some other format would be the cleanest but maybe not all people enjoy doing something like this. The solutions I can think of are: Create a configuration file in XML or similar and with a prespecified format. Pass the information during initialization of the module. Use the first row of the data as headers and try to guess types (ouch) Surely there must be a "canonical" way of doing this that is also usable and efficient. Thanks p.

  • PHP: saving multiple tuples to the same table

    - by Binaryrespawn
    Hi all, I am trying to save data into the same table several times from the same $_POST array. You see, on my registration form a family is allowed to specify the names, gender and age of all members they wish to bring along. This data is being stored in a database table called aditional_member. Based on family size, I am dynamically generating html table rows where each row has the number of input fields required. <tr id="additionalmember_3"> <td><input type="text" name="first_name1" maxlength="50" value="" /></td> <td><input type="text" name="last_name1" maxlength="50" value="" /></td> td><select name="gender1" value="" ><option value='Male'>Male</option><option value='Female'>Female</option></select></td> <td><select name="age_group"value="" ><option value='18 to 30'>18 to 30</option><option value='31 to 60'>31 to 60</option></select></td> </tr> When I POST, let us say I have three sets of input(3 table rows as above), Is there a simple way to insert into the addional_member table the data from row one, then row two, and so on. I tried looping the insert statement, which failed. I am basically open to suggestions, I do not need to use a table. Any ideas, Thank you.

  • Hibernate: Querying objects by attributes of inherited classes

    - by MichaelD
    Hi all, I ran into a problem with Hibernate concerning queries on classes which use inheritance. Basically I've the following class hierarchy: @Entity @Table( name = "recording" ) class Recording { ClassA attributeSet; ... } @Entity @Inheritance( strategy = InheritanceType.JOINED ) @Table( name = "classA" ) public class ClassA { String Id; ... } @Entity @Table( name = "ClassB1" ) @PrimaryKeyJoinColumn( name = "Id" ) public class ClassB1 extends ClassA { private Double P1300; private Double P2000; } @Entity @Table( name = "ClassB2" ) @PrimaryKeyJoinColumn( name = "Id" ) public class ClassB2 extends ClassA { private Double P1300; private Double P3000; } The hierarchy is already given like this and I cannot change it easily. As you can see ClassB1 and ClassB2 inherit from ClassA. Both classes contain a set of attributes which sometimes even have the same names (but I can't move them to ClassA since there are possible more sub-classes which do not use them). The Recording class references one instance of one of this classes. Now my question: What I want to do is selecting all Recording objects in my database which refer to an instance of either ClassB1 or ClassB2 with e.g. the field P1300 == 15.5 (so this could be ClassB1 or ClassB2 instances since the P1300 attribute is declared in both classes). What I tried is something like this: Criteria criteria = session.createCriteria(Recording.class); criteria.add( Restrictions.eq( "attributeSet.P1300", new Double(15.5) ) ); criteria.list(); But since P1300 is not an attribute of ClassA hibernate throws an exception telling me: could not resolve property: P1300 of: ClassA How can I tell hibernate that it should search in all subclasses to find the attribute I want to filter? Thanks MichaelD

  • diffuculty in appending images dynamically in an Custom List View

    - by ganesh
    Hi I have written an custom List view which binds images according to the result from a feed @Override public View getView(int position, View convertView, ViewGroup parent) { ViewHolder holder; if (convertView == null) { convertView = mInflater.inflate(R.layout.row_for_stopnames, null); holder = new ViewHolder(); holder.name = (TextView)convertView.findViewById(R.id.stop_name); holder.dis = (TextView)convertView.findViewById(R.id.distance); holder.route_one=(ImageView)convertView.findViewById(R.id.one); holder.route_two=(ImageView)convertView.findViewById(R.id.two); holder.route_three=(ImageView)convertView.findViewById(R.id.three); convertView.setTag(holder); } else { holder = (ViewHolder) convertView.getTag(); } holder.name.setText(elements.get(position).get("stop_name")); holder.dis.setText(elements.get(position).get("distance")); String[] route_txt=elements.get(position).get("route_name").split(","); for(int i=0;i<route_txt.length;i++) { if(i==0) { holder.route_one.setBackgroundResource(Utils.getRouteImage().get(stop_txt[0])); } else if(i==1) { holder.route_two.setBackgroundResource(Utils.getRouteImage().get(stop_txt[1])); } else if(i==2) { holder.route_three.setBackgroundResource(Utils.getRouteImage().get(stop_txt[2])); } } convertView.setOnClickListener(new OnItemClickListener(position,elements)); return convertView; } class ViewHolder { TextView name; TextView dis; ImageView route_one; ImageView route_two; ImageView route_three; } for every stop name there may be route_names, maximum of three routes.I have to bind images according to the number of route names.This is what I tried to do by the above code .This works fine until I start scrolling up and down .When I do so the route images gets displayed where it does not want to be,this behaviour is unpredictable.I will be glad if someone explain me why this happens,and the best way to do this.The getRouteImage method of Utils class returns HashMap with key String and value a drawable

  • Perl : get substring which matches refex error

    - by Michael Mao
    Hi all: I am very new to Perl, so please bear with my simple question: Here is the sample output: Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-8008) 2. flightsandroomsonly ($-10102) 3. agent10479475hv ($-10663) Most successful agents in the Emarket climate are (in order of success): 1. agent10896761 ($-7142) 2. agent10479475hv ($-8982) 3. flightsandroomsonly ($-9124) I am interested only in agent names as well as their corresponding balances, so I am hoping to get the following output: agent10896761 -8008 flightsandroomsonly -10102 agent10479475hv -10663 agent10896761 -7142 agent10479475hv -8982 flightsandroomsonly -9124 For later processes. This is the code I've got so far: #!/usr/bin/perl -w open(MYINPUTFILE, $ARGV[0]); while(<MYINPUTFILE>) { my($line) = $_; chomp($line); # regex match test if($line =~ m/agent10479475/) { if($line =~ m/($-[0-9]+)/) { print "$1\n"; } } if($line =~ m/flightsandroomsonly/) { print "$line\n"; } } The second regex match has nothing wrong, 'cause that is printing out the whole line. However, for the first regex match, I've got some other output such like: $ ./compareResults.pl 3.txt 2. flightsandroomsonly ($-10102) 0479475 0479475 3. flightsandroomsonly ($-9124) 1. flightsandroomsonly ($-8053) 0479475 1. flightsandroomsonly ($-6126) 0479475 If I "escape" the braces like this if($line =~ m/\($-[0-9]+\)/) { print "$1\n"; } Then there is never a match for the first regex... So I stuck with a problem of making that particular regex work. Any hints for this? Many thanks in advance.

  • JPA - Entity design problem

    - by Yatendra Goel
    I am developing a Java Desktop Application and using JPA for persistence. I have a problem mentioned below: I have two entities: Country City Country has the following attribute: CountryName (PK) City has the following attribute: CityName Now as there can be two cities with same name in two different countries, the primaryKey for City table in the datbase is a composite primary key composed of CityName and CountryName. Now my question is How to implement the primary key of the City as an Entity in Java @Entity public class Country implements Serializable { private String countryName; @Id public String getCountryName() { return this.countryName; } } @Entity public class City implements Serializable { private CityPK cityPK; private Country country; @EmbeddedId public CityPK getCityPK() { return this.cityPK; } } @Embeddable public class CityPK implements Serializable { public String cityName; public String countryName; } Now as we know that the relationship from Country to City is OneToMany and to show this relationship in the above code, I have added a country variable in City class. But then we have duplicate data(countryName) stored in two places in the City class: one in the country object and other in the cityPK object. But on the other hand, both are necessary: countryName in cityPK object is necessary because we implement composite primary keys in this way. countryName in country object is necessary because it is the standard way of showing relashionship between objects. How to get around this problem?

  • ASP MVC - Routing Required?

    - by evo_9
    I've been reading up on MVC2 which came in VS2010 and it sounds pretty interesting. I'm actually in the middle of a large multi-tenant application project, and have just started coding the UI. I'm considering changing to MVC as I'm not that far along at this point. I have some questions about the Routing capabilities, namely are they required to use MVC or can I more or less ignore Routing? Or do I have to setup a default routing record that will make things work like standard ASPX (as far as routing alone is concerned)? The reason why I don't want to use Routing is because I've already defined a custom URL 'rewrite' mechanism of my own (which fires on session_start). In addition, I'm using jquery and opens-standards for the entire UI, and MVC's aspx overhead-free approach seems like a better fit based on how I've already started to build the application (I am not using viewstate at all, for example). I guess my big concern is whether the routing can be ignored, of if I will have to re-implement my custom URL rewriting to work with MVC, and if that's the case, how would I do that? As a new Routing routine, or stick with the session_start (if that's even possible?). Lastly, I don't want to use anything even remotely 'intelligent/readable' for the url - for a site like StackOverflow, the readability of the URL is a positive, but the opposite is true if it's not a public website like this one. In fact, it would seem to me that the more friendly MVC routing URL (which indirectly show method names) could pose a security risk on a private, non-public website app like I'm developing. For all these reasons I would love to use the lightweight aspects of MVC but skip the Routing entirely - is this possible?

  • Rename files and directories using substitution and variables

    - by rednectar
    I have found several similar questions that have solutions, except they don't involve variables. I have a particular pattern in a tree of files and directories - the pattern is the word TEMPLATE. I want a script file to rename all of the files and directories by replacing the word TEMPLATE with some other name that is contained in the variable ${newName} If I knew that the value of ${newName} was say "Fred lives here", then the command find . -name '*TEMPLATE*' -exec bash -c 'mv "$0" "${0/TEMPLATE/Fred lives here}"' {} \; will do the job However, if my script is: newName="Fred lives here" find . -name '*TEMPLATE*' -exec bash -c 'mv "$0" "${0/TEMPLATE/${newName}}"' {} \; then the word TEMPLATE is replaced by null rather than "Fred lives here" I need the "" around $0 because there are spaces in the path name, so I can't do something like: find . -name '*TEMPLATE*' -exec bash -c 'mv "$0" "${0/TEMPLATE/"${newName}"}"' {} \; Can anyone help me get this script to work so that all files and directories that contain the word TEMPLATE have TEMPLATE replaced by whatever the value of ${newName} is eg, if newName="A different name" and a I had directory of /foo/bar/some TEMPLATE directory/with files then the directory would be renamed to /foo/bar/some A different name directory/with files and a file called some TEMPLATE file would be renamed to some A different name file

  • Can I connect to SQL from JavaScript MVC?

  • RegisterClientScriptInclude doesn't work for some reason...

    - by Andrew
    Hey, I've spent at least 2 days trying anything and googling this...but for some reason I can't get RegisterClientScriptInclude to work the way everyone else has it working? First off, I am usting .NET 3.5 Ajax,...and I am including javascript in my partial page refreshes...using this code: ScriptManager.RegisterClientScriptBlock(this, typeof(Page), "MyClientCode", script, true); It works perfectly, my javascript code contained in the script variable is included every partial refresh. The javascript in script is actually quite extensive though, and I would like to store it in a .js file,..so logically I make a .js file and try to include it using RegisterClientScriptInclude ...however i can't for the life of my get this to work. here's the exact code: ScriptManager.RegisterClientScriptInclude(this, typeof(Page), "mytestscript", "/js/testscript.js"); the testscript.js file is only included in FULL page refreshes...ie. when I load the page, or do a full postback....i can't get the file to be included in partial refreshes...have no idea why..when viewing the ajax POST in firebug I don't see a difference whether I include the file or not.... both of the ScriptManager Includes are being ran from the exact same place in "Page_Load"...so they should execute every partial refresh (but only the ScriptBlock does). anyways,..any help or ideas,..or further ways I can trouble shoot this problem, would be appreciated. Thanks, Andrew

  • Auditing front end performance on web application

    - by user1018494
    I am currently trying to performance tune the UI of a company web application. The application is only ever going to be accessed by staff, so the speed of the connection between the server and client will always be considerably more than if it was on the internet. I have been using performance auditing tools such as Y Slow! and Google Chrome's profiling tool to try and highlight areas that are worth targeting for investigation. However, these tools are written with the internet in mind. For example, the current suggestions from a Google Chrome audit of the application suggests is as follows: Network Utilization Combine external CSS (Red warning) Combine external JavaScript (Red warning) Enable gzip compression (Red warning) Leverage browser caching (Red warning) Leverage proxy caching (Amber warning) Minimise cookie size (Amber warning) Parallelize downloads across hostnames (Amber warning) Serve static content from a cookieless domain (Amber warning) Web Page Performance Remove unused CSS rules (Amber warning) Use normal CSS property names instead of vendor-prefixed ones (Amber warning) Are any of these bits of advice totally redundant given the connection speed and usage pattern? The users will be using the application frequently throughout the day, so it doesn't matter if the initial hit is large (when they first visit the page and build their cache) so long as a minimal amount of work is done on future page views. For example, is it worth the effort of combining all of our CSS and JavaScript files? It may speed up the initial page view, but how much of a difference will it really make on subsequent page views throughout the working day? I've tried searching for this but all I keep coming up with is the standard internet facing performance advice. Any advice on what to focus my performance tweaking efforts on in this scenario, or other auditing tool recommendations, would be much appreciated.

  • FF extension: saving a value in preferences and retrieving in the js file

    - by encryptor
    I am making an extension which should take a link as the user input only once. Then the entire extension keeps using that link on various functions in the JS file. When the user changes it, the value accessed by the js file also changes accordingly. I am using the following but it does not work for me var pref_manager = Components.classes["@mozilla.org/preferencesservice;1"].getService(Components.interfaces.nsIPrefService) function setInstance(){ if (pref_manager.prefHasUserValue("myvar")) { instance = pref_manager.getString("myvar"); alert(instance); } if(instance == null){ instance = prompt("Please enter webcenter host and port"); // Setting the value pref_manager.setString("myvar", instance); } } instance is the global variable in which i take the user input. The alert (instance) does not show up, which means there is some problem by the way i am saving the pref or extracting it. Can someone please help me with this. I have never worked with preferences before. so even if there are minor problems i might not be able to figure out.

  • How do I iterate over a collection that is in an object passed as parameter in a jasper report?

    - by spderosso
    Hi, I have an object A that has as an instance variable a collection of object Bs. Example: public class A{ String name; List<B> myList; ... public List<B> getMyList(){ return myList; } ... } I want this object to be the only source of information the jasper report gets, since all the information the report need is in A. I am currently doing something like: A myObjectA = new A(...); InputStream reportFile = MyPage.this.getClass().getResourceAsStream("test.jrxml"); HashMap<String, Object> parameters = new HashMap<String, Object>(); parameters.put("objectA", myObjectA); ... JasperReport report = JasperCompileManager.compileReport(reportFile); JasperPrint print = JasperFillManager.fillReport(report, parameters, new JRBeanCollectionDataSource(myObjectA.getMyList())); return JasperExportManager.exportReportToPdf(print); thereby passing "two" parameters, the objectA as a concrete parameter and the collection of object Bs that is in A as a bean data source. How do I iterate over the Bs in A by passing only A? Thanks!

  • How should I name a native DLL distributed in both 32-bit and 64-bit form?

    - by Spike0xff
    I have a commercial product that's a DLL (native 32-bit code), and now it's time to build a 64-bit version of it. So when installing on 64-bit Windows, the 32-bit version goes into Windows\SysWOW64, and the 64-bit version goes into... Windows\System32! (I'm biting my tongue here...) Or the DLL(s) can be installed alongside the client application. What should I name the 64-bit DLL? Same name as 32-bit: Two files that do the same thing, have the same name, but are totally non-interchangeable. Isn't that a recipe for confusion and support problems? Different names (e.g. product.dll and product64.dll): Now client applications have to know whether they are running 32-bit or 64-bit in order to reference my DLL, and there are languages where that isn't known until run-time - .NET being just one example. And now all the statically compiled clients have to conditionalize the import declarations: IF target=WIN64 THEN import Blah from "product64.dll" ELSE import Blah from "product.dll" ENDIF The product contains massive amounts of C code, and a large chunk of C++ - porting it to C# is not an option. Advice? Suggestions?

  • Set "Start With" value for Oracle sequence dynamically

    - by Allan
    I'm trying to create a release script that can be deployed on multiple databases, but where the data can be merged back together at a later date. The obvious way to handle this is to set the sequence numbers for production data sufficiently high in subsequent deployments to prevent collisions. The problem is in coming up with a release script that will accept the environment number and set the "Start With" value of the sequences appropriately. Ideally, I'd like to use something like this: ACCEPT EnvironNum PROMPT 'Enter the Environment Number: ' --[more scripting] CREATE SEQUENCE seq1 START WITH &EnvironNum*100000; --[more scripting] This doesn't work because you can't evaluate a numeric expression in DDL. Another option is to create the sequences using dynamic SQL via PL/SQL. ACCEPT EnvironNum PROMPT 'Enter the Environment Number: ' --[more scripting] EXEC execute immediate 'CREATE SEQUENCE seq1 START WITH ' || &EnvironNum*100000; --[more scripting] However, I'd prefer to avoid this solution as I generally try to avoid issuing DDL in PL/SQL. Finally, the third option I've come up with is simply to accept the Start With value as a substitution variable, instead of the environment number. Does anyone have a better thought on how to go about this?

  • How to detect if a file is PDF or TIFF ?

    - by eviljack
    Please bear with me as I've been thrown into the middle of this project without knowing all the background. If you've got WTF questions, trust me, I have them too. Here is the scenario: I've got a bunch of files residing on an IIS server. They have no file extension on them. Just naked files with names like "asda-2342-sd3rs-asd24-ut57" and so on. Nothing intuitive. The problem is I need to serve up files on an ASP.NET (2.0) page and display the tiff files as tiff and the PDF files as PDF. Unfortunately I don't know which is which and I need to be able to display them appropriately in their respective formats. For example, lets say that there are 2 files I need to display, one is tiff and one is PDF. The page should show up with a tiff image, and perhaps a link that would open up the PDF in a new tab/window. The problem: As these files are all extension-less I had to force IIS to just serve everything up as TIFF. But if I do this, the PDF files won't display. I could change IIS to force the MIME type to be PDF for unknown file extensions but I'd have the reverse problem. http://support.microsoft.com/kb/326965 Is this problem easier than I think or is it as nasty as I am expecting?

  • How do I mock a method with an open array parameter in PascalMock?

    - by Oliver Giesen
    I'm currently in the process of getting started with unit testing and mocking for good and I stumbled over the following method that I can't seem to fabricate a working mock implementation for: function GetInstance(const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID = CID_DEFAULT): Boolean; (TImplContextID is just an alias for Integer) I thought it would have to look something like this: function TImplementationProviderMock.GetInstance( const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID): Boolean; begin Result := AddCall('GetInstance') .WithParams([@AIID, AContextID]) .ReturnsOutParams([AInstance]) .ReturnValue; end; But the compiler complains about the .ReturnsOutParams([AInstance]) saying "Bad argument type in variable type array constructor.". Also I haven't found a way to specify the open array parameter AArgs at all. Also, is using the @-notation for the TGUID-typed parameter the right way to go? Is it possible to mock this method with the current version of PascalMock at all? Update: I now realize I got the purpose of ReturnsOutParams completely wrong: It's intended to be used for populating the values to be returned when defining the expectations rather than for mocking the call itself. I now think the correct syntax for mocking the out parameter would probably have to look more like this: function TImplementationProviderMock.GetInstance( const AIID: TGUID; out AInstance; const AArgs: array of const; const AContextID: TImplContextID): Boolean; var lCall: TMockMethod; begin lCall := AddCall('GetInstance').WithParams([@AIID, AContextID]); Pointer(AInstance) := lCall.OutParams[0]; Result := lCall.ReturnValue; end; The questions that remain are how to mock the open array parameter AArgs and whether passing the TGUID argument (i.e. a value type) by address will work out...

  • SQL: select rows with the same order as IN clause

    - by Andrea3000
    I know that this question has been asked several times and I've read all the answer but none of them seem to completely solve my problem. I'm switching from a mySQL database to a MS Access database with MS SQL. In both of the case I use a php script to connect to the database and perform SQL queries. I need to find a suitable replacement for a query I used to perform on mySQL. I want to: perform a first query and order records alphabetically based on one of the columns construct a list of IDs which reflects the previous alphabetical order perform a second query with the IN clause applied with the IDs' list and ordered by this list. In mySQL I used to perform the last query this way: SELECT name FROM users WHERE id IN ($name_ids) ORDER BY FIND_IN_SET(id,'$name_ids') Since FIND_IN_SET is available only in mySQL and CHARINDEX and PATINDEX are not available from my php script, how can I achieve this? I know that I could write something like: SELECT name FROM users WHERE id IN ($name_ids) ORDER BY CASE id WHEN ... THEN 1 WHEN ... THEN 2 WHEN ... THEN 3 WHEN ... THEN 4 END but you have to consider that: IDs' list has variable length and elements because it depends on the first query that list can easily contains thousands of elements Have you got any hint on this? Is there a way to programmatically construct the ORDER BY CASE ... WHEN ... statement? Is there a better approach since my list of IDs can be big?

  • Error in Ordinary Differential Equation representation

    - by Priya M
    UPDATE I am trying to find the Lyapunov Exponents given in link LE. I am trying to figure it out and understand it by taking the following eqs for my case. These are a set of ordinary differential equations (these are just for testing how to work with cos and sin as ODE) f(1)=ALPHA*(y-x); f(2)=x*(R-z)-y; f(3) = 10*cos(x); and x=X(1); y=X(2); cos(y)=X(3); f1 means dx/dt;f2 dy/dt and f3 in this case would be -10sinx. However,when expressing as x=X(1);y=X(2);i am unsure how to express for cos.This is just a trial example i was doing so as to know how to work with equations where we have a cos,sin etc terms as a function of another variable. When using ode45 to solve these Eqs [T,Res]=sol(3,@test_eq,@ode45,0,0.01,20,[7 2 100 ],10); it throws the following error ??? Attempted to access (2); index must be a positive integer or logical. Error in ==> Eq at 19 x=X(1); y=X(2); cos(x)=X(3); Is my representation x=X(1); y=X(2); cos(y)=X(3); alright? How to resolve the error? Thank you

  • Turning on multiple result sets in an ODBC connection to SQL Server

    - by David Griffiths
    I have an application that originally needed to connect to Sybase (via ODBC), but I've needed to add the ability to connect to SQL Server as well. As ODBC should be able to handle both, I thought I was in a good position. Unfort, SQL Server will not let me, by default, nest ODBC commands and ODBCDataReaders - it complains the connection is busy. I know that I had to specify that multiple active result sets (MARS) were allowed in similar circumstances when connecting to SQL Server via a native driver, so I thought it wouldn't be an issue. The DSN wizard has no entr y when creating a SystemDSN. Some people have provided registry hacks to get around this, but this did not work (add a MARS_Connection with a value of Yes to HKEY_LOCAL_MACHINE\SOFTWARE\ODBC\ODBC.INI\system-dsn-name). Another suggestion was to create a file-dsn, and add "MARS_Connection=YES" to that. Didn't work. Finally, a DSN-less connection string. I've tried this one (using MultipleActiveResultSets - same variable as a Sql Server connection would use), "Driver={SQL Native Client};Server=xxx.xxx.xxx.xxx;Database=someDB;Uid=u;Pwd=p;MultipleActiveResultSets=True;" and this one: "Driver={SQL Native Client};Server=192.168.75.33\\ARIA;Database=Aria;Uid=sa;Pwd=service;MARS_Connection=YES;" I have checked the various connection-string sites - they all suggest what I've already tried.

  • Is there a way to control how pytest-xdist runs tests in parallel?

    - by superselector
    I have the following directory layout: runner.py lib/ tests/ testsuite1/ testsuite1.py testsuite2/ testsuite2.py testsuite3/ testsuite3.py testsuite4/ testsuite4.py The format of testsuite*.py modules is as follows: import pytest class testsomething: def setup_class(self): ''' do some setup ''' # Do some setup stuff here def teardown_class(self): '''' do some teardown''' # Do some teardown stuff here def test1(self): # Do some test1 related stuff def test2(self): # Do some test2 related stuff .... .... .... def test40(self): # Do some test40 related stuff if __name__=='__main()__' pytest.main(args=[os.path.abspath(__file__)]) The problem I have is that I would like to execute the 'testsuites' in parallel i.e. I want testsuite1, testsuite2, testsuite3 and testsuite4 to start execution in parallel but individual tests within the testsuites need to be executed serially. When I use the 'xdist' plugin from py.test and kick off the tests using 'py.test -n 4', py.test is gathering all the tests and randomly load balancing the tests among 4 workers. This leads to the 'setup_class' method to be executed every time of each test within a 'testsuitex.py' module (which defeats my purpose. I want setup_class to be executed only once per class and tests executed serially there after). Essentially what I want the execution to look like is: worker1: executes all tests in testsuite1.py serially worker2: executes all tests in testsuite2.py serially worker3: executes all tests in testsuite3.py serially worker4: executes all tests in testsuite4.py serially while worker1, worker2, worker3 and worker4 are all executed in parallel. Is there a way to achieve this in 'pytest-xidst' framework? The only option that I can think of is to kick off different processes to execute each test suite individually within runner.py: def test_execute_func(testsuite_path): subprocess.process('py.test %s' % testsuite_path) if __name__=='__main__': #Gather all the testsuite names for each testsuite: multiprocessing.Process(test_execute_func,(testsuite_path,))

  • XSLT: generate multiple object by incrementing attribute and value

    - by Daniel
    Hi, I have a xml as below that I'd like to copy n times while incrementing one of its element and one of its attribute. XML input: <Person position=1> <name>John</name> <number>1</number> <number>1</number> </Person> and I'd like something like below with the number of increment to be a variable. XML output: <Person position=1> <name>John</name> <number>1</number> </Person> <Person position=2> <name>John</name> <number>2</number> </Person> .... <Person position=n> <name>John</name> <number>n</number> </Person> Any clue

  • Limit iPhone in-app purchase by user's country

    - by Ryan
    Hello everyone. I'm a product manager who works for a small internet company that is developing an iPhone application for a social network. We monetize by offering limited and premium memberships to users (premium members get additional features not available to limited members). For billing on the web, we use a 3rd-party payment gateway that is nearing retirement, and will be replaced by an in-house solution. The business wants a global launch for our iPhone app using iTunes + in-app purchasing as a payment gateway. The problem with going global using this payment method is that for our web service membership level, available features, and subscription costs are defined by country. For example, in the US premium/limited memberships are available at 5 pricing tiers; in France premium/limited memberships are available at 5 different pricing tiers from the US; and in Chile the service is available for free and all features are available to users. Is it possible then to have the server-side, based on the user's country of registration, control the level of access, features, and payment options for users on the iPhone? I'd also note that since iTunes Connect does not allow variable pricing by currency and country, each "region" would need 5 in app purchase options. I argued for a US-only launch for iPhone using iTunes in app purchase until an in-house payment gateway is available. But you know...
