  • MSSQL "for xml", multiple tables, multiple nodes

    - by Nelson
    Is it possible to select multiple tables at once? For example, I can do: SELECT ( SELECT * FROM Articles FOR XML PATH('article'), TYPE ) FOR XML PATH('articles'), ROOT('data') and SELECT ( SELECT * FROM ArticleTypes FOR XML PATH('articleType'), TYPE ) FOR XML PATH('articleTypes'), ROOT('data') Can I join both so that I get the following output? I can't use UNION because the table structures don't match. <data> <articles> <article>...</article> ... </articles> <articleTypes> <articleType>...</articleType> ... </articleTypes> </data>

  • Confusion about Nullable<T> constraints

    - by n535
    Greetings everybody. I am sorry, if this was already asked before (searched in vain) or is really very simple, but i just can't get it. The MSDN definition of a Nullable type, states, that it is defined in a following manner: [SerializableAttribute] public struct Nullable<T> where T : struct, new() So the question is quite straightforward: How is this definition possible? Or this is just a typo? Every value type already has a default constructor. Indeed, when i try to compile something like this, the compiler reasonably says, that it is illegal to apply both constraints at the same time, because the second one is implicitly included in a first one. Thanks in advance.

  • Disable page cache on a specific page

    - by David Brunelle
    Hi, Not sure if I really am on the right forum, but if not, just tell me. I have a page that is coded in ASP (not .net) which is used to send email. We are currently having a problem in which the page seem to be sent twice sometime. Upon checking, we found out that those who have this problem are coming from big organisation, so it was suggested that their server might cache the file for some reason. I would like to know, is there a way in HTML (or ASP ) to prevent that from happening ? Or is it in IIS that we must set this up ? Thanks,

  • Installing a .NET framework on Windows 7?

    - by user23392
    I just switched to windows 7 from Vista and a lot of programs/games don't work anymore. The issue is that some games need a specific .NET framework version. when I try to install that it says that I should turn on/off windows features. I go to that and I find .NET framework in the list and tried both checking it and unchecking it. Both don't work and I still get the message that I need to turn on/off that thing. Any suggestion please? I have Windows 7 Ultimate 32-bit.

  • NHibernate very slow during debugging

    - by HeavyWave
    Have anyone stumbled upon a problem where NHibernate is extremely slow in Visual Studio while debugging, but behaves normally when run separately? Logging is disabled and the time lost seems to be when the actual queries are executed, NHProfiler shows that queries were executed very quickly (on SQL side I presume), but each session with 10 queries takes about 4 seconds. I am using SQL Express Server. As I said, even if I turn on full logging and run my application without Visual Studio it is a magnitude faster. Update. After hours and hours of work towards the issue I was able to fix it by simply switching project type from Windows Application to Console Application (although in reality it's a Windows Service, but it always worked before with Windows Application project type). What could possibly be the difference to bring NHibernate to a halt in debugging mode?

  • MVC route with id and sub-action

    - by Dan Revell
    I can't figure out what I need to do with MVC routing to make this work Here's my one route: routes.MapHttpRoute( name: "DefaultApi", routeTemplate: "{controller}/{id}/{action}", defaults: new { id = RouteParameter.Optional, action = RouteParameter.Optional } ); The request /Shipments/ works great. The request /Shipments/3/Packages works great. The request /Shipments/3 however fails with the error: Multiple actions were found that match the request: System.Linq.IQueryable`1[Api.Controllers.RequisitionsController+PackageRequisitionWithTracking] GetPackageRequisitions(Int32) on type Api.Controllers.RequisitionsController Api.Models.ShipmentRequisition GetShipmentRequisitions(Int32) on type Api.Controllers.RequisitionsController It can't seem to differentiate between: public ShipmentRequisition GetShipmentRequisitions(int id) and [ActionName("Packages")] public IQueryable<PackageRequisitionWithTracking> GetPackageRequisitions(int id) I would have thought the lack of action name on the get shipment by id would allow that route to work.

  • Dreamweaver utf-8 encoded php page displays wrong chinese character in IE and Chrome, correct in FF

    - by user1334485
    I have an issue with character encoding: I have this page: http://www.studiomille.jp/class/ (its in japanese but the character in question is from chinese i think) FF shows it correctly, IE (all versions) and Chrome doesn't (sorry larger screenshots): FF Screenshot: IE Screenshot: (there are other character that are different throughout the site, this is just one example) Everything is set to UTF-8: * PHP sends header: Content-Type:text/html; charset=UTF-8 * PHP starts with: mb_language('uni'); mb_internal_encoding('UTF-8'); * meta tag: <meta http-equiv="Content-Type" content="text/html; charset=utf-8"/> * all files are saved with UTF-8 encoding with DreamWeaver CS3 * the same font is used in all the browsers. On that page nothing comes from the db, everything is hard coded. The site has the same behavior on my localhost too. So why only FF gets it right and how can I make it work on IE also?

  • How can I create a new class instance from a class within a (static) class?

    - by Mervin
    I'm new to Java (have experience with C#), This is what i want to do: public final class MyClass { public class MyRelatedClass { ... } } public class OtherRandomClass { public void DoStuff() { MyRelatedClass data = new MyClass.MyRelatedClass(); } } which gives this error in Eclipse: "No enclosing instance of type BitmapEffects is accessible. Must qualify the allocation with an enclosing instance of type BitmapEffects (e.g. x.new A() where x is an instance of BitmapEffects)." this is possible in C# with static classes , how should it be done here?

  • Adding a child node to a JSON node dynamically

    - by Sai
    I have to create a nested multi level json depending on the resultset that I get from MYSQL. I created a json object initially. Now I want to add child nodes to the already child nodes in the object. d = collections.OrderedDict() jsonobj = {"test": dict(updated_at="today", ID="ID", ads=[])} for rows1 in rs: jsonobj['list']["ads"].append(dict(unit = "1", type ="ad_type", id ="123", updated_at="today", x_id="111", x_name="test")) cur.execute("SELECT * from f_test") rs1 = cur.fetchall() for rows2 in rs1: propertiesObj = [] d["name"]="propName" d["type"]="TypeName" d["value"]="Value1" propertiesObj.append(d) jsonobj['play_list']["ads"].append() Here in the above line I want to add another child node to [play_list].[ads] which is a array list again. the output should look like the following [list].[ads].[preferences].

  • How Do I Make A Bash Script for Git Checkin/Checkout?

    - by ServerChecker
    I was thinking of bringing up a git service on an Ubuntu server. However, the way me and another programmer operate -- we really want to try and stick to one person working on a project at a time. How would I make a Bash script to create a check in and check out with git? We want to prevent anyone from checking in code that hasn't already been checked in, and it should error out with the name of the person who has the code checked out. EDIT: I'm not really interested in using Git with its fantastic diff features. I move 100mph and don't have time to play diff games with the other developers. That's why we're using Git. If the other developers want to play the diff game, they can still do so. But when I check something out, I want it locked to everyone until I check it back in again.

  • Writing a managed wrapper for unmanaged (C++) code - custom types/structs

    - by Bobby
    faacEncConfigurationPtr FAACAPI faacEncGetCurrentConfiguration( faacEncHandle hEncoder); I'm trying to come up with a simple wrapper for this C++ library; I've never done more than very simple p/invoke interop before - like one function call with primitive arguments. So, given the above C++ function, for example, what should I do to deal with the return type, and parameter? FAACAPI is defined as: #define FAACAPI __stdcall faacEncConfigurationPtr is defined: typedef struct faacEncConfiguration { int version; char *name; char *copyright; unsigned int mpegVersion; unsigned long bitRate; unsigned int inputFormat; int shortctl; psymodellist_t *psymodellist; int channel_map[64]; } faacEncConfiguration, *faacEncConfigurationPtr; AFAIK this means that the return type of the function is a reference to this struct? And faacEncHandle is: typedef struct { unsigned int numChannels; unsigned long sampleRate; ... SR_INFO *srInfo; double *sampleBuff[MAX_CHANNELS]; ... double *freqBuff[MAX_CHANNELS]; double *overlapBuff[MAX_CHANNELS]; double *msSpectrum[MAX_CHANNELS]; CoderInfo coderInfo[MAX_CHANNELS]; ChannelInfo channelInfo[MAX_CHANNELS]; PsyInfo psyInfo[MAX_CHANNELS]; GlobalPsyInfo gpsyInfo; faacEncConfiguration config; psymodel_t *psymodel; /* quantizer specific config */ AACQuantCfg aacquantCfg; /* FFT Tables */ FFT_Tables fft_tables; int bitDiff; } faacEncStruct, *faacEncHandle; So within that struct we see a lot of other types... hmm. Essentially, I'm trying to figure out how to deal with these types in my managed wrapper? Do I need to create versions of these types/structs, in C#? Something like this: [StructLayout(LayoutKind.Sequential)] struct faacEncConfiguration { uint useTns; ulong bitRate; ... } If so then can the runtime automatically "map" these objects onto eachother? And, would I have to create these "mapped" types for all the types in these return types/parameter type hierarchies, all the way down until I get to all primitives? I know this is a broad topic, any advice on getting up-to-speed quickly on what I need to learn to make this happen would be very much appreciated! Thanks!

  • Styling WPF Toolkit DataGrid Column Headers

    - by ChrisFletcher
    Hi, I'm having an issue styling the WPF Datagrid, I've styled the column headers (of type ColumnHeader). But when the data in the columns does not fill the full width of the grid an additional column is added to pad out the grid. This column ignores the ColumnHeader style and looks out of place presumably because the element has a different type, I've looked through the library in object browser but I can't find this element. I've also considered fixing the sizes so this column is unnecessary but thats not a viable option. The problem is demonstrated in the following article: http://blogs.msdn.com/jaimer/archive/2009/01/20/styling-microsoft-s-wpf-datagrid.aspx The element I mean is in the top right, just to the right of green column 3 and just above the cell with the row background arrow.

  • Server downtime - are these APC warnings the cause?

    - by DisgruntledGoat
    Yesterday I had a problem with my dedicated server (Ubuntu 10.04, LAMP). It wasn't down per se, but running incredibly slowly as if we had a massive overload of visitors (though I don't think we did). It's running smoothly again now. I've been checking through log files etc to see if I can find any issues, the only strange thing is a bunch of these errors, occurring at about the same time as the downtime: [apc-warning] Unable to allocate memory for pool. in [file] on line 49. And a bit later on: [apc-warning] GC cache entry '[file1]' (dev=2056 ino=8988092) was on gc-list for 3601 seconds in [file2] on line 746. Could these errors indicate the cause of the server slowdown, or are they simply a result of the server being slow in the first place? What would be the solution?

  • In Python, how to use a C++ function which returns an allocated array of structs via a ** parameter?

    - by Jon-Eric
    I'd like to use some existing C++ code, NvTriStrip, in a Python tool. SWIG easily handles the functions with simple parameters, but the main function, GenerateStrips, is much more complicated. What do I need to put in the SWIG interface file to indicate that primGroups is really an output parameter and that it must be cleaned up with delete[]? /////////////////////////////////////////////////////////////////////////// // GenerateStrips() // // in_indices: input index list, the indices you would use to render // in_numIndices: number of entries in in_indices // primGroups: array of optimized/stripified PrimitiveGroups // numGroups: number of groups returned // // Be sure to call delete[] on the returned primGroups to avoid leaking mem // bool GenerateStrips( const unsigned short* in_indices, const unsigned int in_numIndices, PrimitiveGroup** primGroups, unsigned short* numGroups, bool validateEnabled = false ); FYI, here is the PrimitiveGroup declaration: enum PrimType { PT_LIST, PT_STRIP, PT_FAN }; struct PrimitiveGroup { PrimType type; unsigned int numIndices; unsigned short* indices; PrimitiveGroup() : type(PT_STRIP), numIndices(0), indices(NULL) {} ~PrimitiveGroup() { if(indices) delete[] indices; indices = NULL; } };

I even tried doing a get against cnn.com and got no response. any ideas? thanks

    Currently I using the following code to get my JSON output from MySQL. <?php $session = mysql_connect('localhost','name','pass'); mysql_select_db('dbname', $session); $result= mysql_query('SELECT message FROM posts', $session); $somethings = array(); while ($row = mysql_fetch_assoc($result)) { $somethings[] = $row; } ?> <script type="text/javascript"> var somethings= <?php echo json_encode($somethings); ?>; </script> And the output is: <script type="text/javascript"> var somethings= [{"message":"Welcome to Yo~ :)"},{"message":"Try iPhone post!"},{"message":"????"}]; </script> Here is the question, how can I change my output into format like : <script type="text/javascript"> userAge = new Array('21','36','20'), userMid = new Array('liuple','anhu','jacksen'); </script> Which I'll be using later with following code : var html = ' <table class="map-overlay"> <tr> <td class="user">' + '<a class="username" href="/' + **userMid[index]** + '" target="_blank"><img alt="" src="' + getAvatar(signImgList[index], '72x72') + '"></a><br> <a class="username" href="/' + **userMid[index]** + '" target="_blank">' + userNameList[index] + '</a><br> <span class="info">' + **userSex[index]** + ' ' + **userAge[index]** + '?<br> ' + cityList[index] + '</span>' + '</td> <td class="content">' + picString + somethings[index] + '<br> <span class="time">' + timeList[index] + picTips + '</span></td> </tr> </table> '; Thanks for helping and reading!

  • Template function as a template argument

    - by Kos
    I've just got confused how to implement something in a generic way in C++. It's a bit convoluted, so let me explain step by step. Consider such code: void a(int) { // do something } void b(int) { // something else } void function1() { a(123); a(456); } void function2() { b(123); b(456); } void test() { function1(); function2(); } It's easily noticable that function1 and function2 do the same, with the only different part being the internal function. Therefore, I want to make function generic to avoid code redundancy. I can do it using function pointers or templates. Let me choose the latter for now. My thinking is that it's better since the compiler will surely be able to inline the functions - am I correct? Can compilers still inline the calls if they are made via function pointers? This is a side-question. OK, back to the original point... A solution with templates: void a(int) { // do something } void b(int) { // something else } template<void (*param)(int) > void function() { param(123); param(456); } void test() { function<a>(); function<b>(); } All OK. But I'm running into a problem: Can I still do that if a and b are generics themselves? template<typename T> void a(T t) { // do something } template<typename T> void b(T t) { // something else } template< ...param... > // ??? void function() { param<SomeType>(someobj); param<AnotherType>(someotherobj); } void test() { function<a>(); function<b>(); } I know that a template parameter can be one of: a type, a template type, a value of a type. None of those seems to cover my situation. My main question is hence: How do I solve that, i.e. define function() in the last example? (Yes, function pointers seem to be a workaround in this exact case - provided they can also be inlined - but I'm looking for a general solution for this class of problems).
