  • Unit testing with Data Access Layer

    - by chobo
    Hi, what is a good way to write unit tests with a LINQ to SQL DAL? Currently I am doing some database testing and need to create helper methods that access the database, but I don't want those methods in my main repo's. So what I have is two copies of the DAL, one in my main project and one in the Test project. Is it easier to manage these things if I create a separate project for the data layer? I'm not sure which way is a better way to approach this. If I do create a data layer project would I move all my repo's to that project as well? I'm not sure how to properly setup the layers. Thanks

  • asp.net mvc - limit access to web pages

    - by niao
    Greetings, in my asp.net mvc application what i would like to do is to enable access to some pages only after user was successfully authorized. I have already created custom membership provider and that works fine. How can I, in web config create such rule - for instance for all pages in ~Admin/ folder? I don't want to create on every controller's action the validation code. For now i have in my web.config the following statement: <location path="~/Admin"> <system.web> <authorization> <deny users="?"/> </authorization> </system.web> but it doesn't work.

  • Dynamic access to tables from another database inside an user function

    - by Alberto Martinez
    I have an user defined table function in SQL Server that aggregate data from several tables including a couple of tables of another database. That is done hardcoding the name of the database in the queries, but we want to make the database name configurable (because our databases usually share the server with the databases of other applications). I tried to construct a dynamic query string inside the function using the database name that is stored in a configuration table, but: When I tried exec(@sqlStatement) SQL Server said that execute string is not allowed inside a function. Then I tried exec sp_executesql @sqlStatement and the function was created, but when you execute it SQL Server says that inside a function you can only run extended functions and procedures. So the question is: is possible create a function or stored procedure that access a table in another database without having to recreate the function when the database name is different? TIA.

  • Access violation C++ (Deleting items in a vector)

    - by Gio Borje
    I'm trying to remove non-matching results from a memory scanner I'm writing in C++ as practice. When the memory is initially scanned, all results are stored into the _results vector. Later, the _results are scanned again and should erase items that no longer match. The error: Unhandled exception at 0x004016f4 in .exe: 0xC0000005: Access violation reading location 0x0090c000. // Receives data DWORD buffer; for (vector<memblock>::iterator it = MemoryScanner::_results.begin(); it != MemoryScanner::_results.end(); ++it) { // Reads data from an area of memory into buffer ReadProcessMemory(MemoryScanner::_hProc, (LPVOID)(*it).address, &buffer, sizeof(buffer), NULL); if (value != buffer) { MemoryScanner::_results.erase(it); // where the program breaks } }

  • 1120: Why can't it access the variable?

    - by Oden
    I'm new at as3, maybe thats the reason why i don't understand, why the setInterval causes an error. <mx:Script> <![CDATA[ import flash.utils.setInterval; import mx.controls.Alert; [Bindable] public var MyInt:int = 500; setInterval(function():void{ ++MyInt; },1000); ]]> </mx:Script> I have a label where the value of MyInt gets visible, the bind works perfect, i've tested it several ways, and i i create a button it grows the number, but if i use the setInterval function i get an error: Access of undefined property myInt. Why? What does cause this? Please explain it, so I can avoid errors like this. Thanks

  • Path variable to mso.dll and msoutl.olb

    - by Stefanie
    Hey, I'm trying to develop a toolbar for Microsoft Outlook. For getting it to work I need mso.dll and msoutl.olb as an import. My problem is: the path is hardcoded , but it varies for every OS and of course if someone doesn't install Office to the default path. I tried it this way http://support.microsoft.com/kb/234788/en-us/ but it didn't work, because I couldn't get the return value I needed (OK, after four type conversions but I thought there had to be a better way ;) ) Thanks for helping

  • Possible to use Javascript to access the client side's network(knowingly)

    - by Earlz
    I recently found an exploit in my router to basically give me root access. The catch? There is a nonce hidden form value that is randomly generated and must be sent in for it to work that makes it difficult to do "easily" So basically I'm wanting to do something like this in javascript: get http://192.168.1.254/blah use a regex or similar to extract the nonce value put the nonce value into a hidden field in the current page submit the form by POST to http://192.168.1.254/blah complete with the nonce value and other form values I want to send in. Is this at all possible using only HTML and Javascript? I'm open to things like "must save HTML file locally and then open", which I'm thinking is one way around the cross domain policy. But anyway, is this at all possible? I'm hoping for this to be able to run from at least Firefox and Chrome. The audience for this is those with some technical know how.

  • C++ Arrays of Structure access

    - by learningtolive
    Hi, I'm studying C++ from Schildt's book and don't quite understand what does he mean under third structure; Can somebody explain this - To access a specific structure within an array of structures, you must index the structure name. For example, to display the on_hand member of the third structure, you would write cout cout << invtry[2].on_hand; Some code: struct type{ char item[40]; double cost; double retail; int on_hand; int lead_time; }invtry[SIZE];

  • Why extremely occasionally will one of bof/eof be true for a new non-empty recordset

    - by jjb
    set recordsetname = databasename.openrecordset(SQLString) if recordsetname.bof <> true and recordsetname.eof <> true then 'do something end if 2 questions : the above test can evaluate to false incorrectly but only extremely rarely (I've had one lurking in my code and it failed today, I believe for the first time in 5 years of daily use-that's how I found it). Why very occasionally will one of bof/eof be true for a non-empty recordset. It seems so rare that I wonder why it occurs at all. Is this a foolproof replacement: if recordsetname.bof <> true or recordsetname.eof <> true then Edit to add details of code : Customers have orders, each order begins with a BeginOrder item and end with an EndOrder item and in between are the items in the order. The SQL is: ' ids are autoincrement long integers ' SQLString = "select * from Orders where type = OrderBegin or type = OrderEnd" Dim OrderOpen as Boolean OrderOpen = False Set rs = db.Openrecordset(SQLString) If rs.bof <> True And rs.eof <> True Then myrec.movelast If rs.fields("type").value = BeginOrder Then OrderOpen = True End If End If If OrderOpen F False Then 'code here to add new BeginOrder Item to Orders table ' End If ShowOrderHistory 'displays the customer's Order history ' In this case which looks this this BeginOrder Item a Item b ... Item n EndOrder BeginOrder Item a Item b ... Item n EndOrder BeginOrder Item a item b ... Item m BeginOrder <----should not be there as previous order still open

  • How much information do pdb files contain? (C# / .NET)

    - by Silver Dragon
    Is is wise to redistribute the pdb files along with a commercial application? Occasionally, I'm using the stack trace to get a more detailed error reporting logs from the deployed applications; can this functionality be achieved without relying to those files? Also, how much hints of the original source code does these files contain? Would it be easier to reverse-engineer my application using it?

  • Ruby on Rails - can't access datetime model object

    - by NomadicRiley
    I've created a model that has 3 string columns and a datetime. Everything is running in SQLite3 and I can view the records in my table just fine using Lita. I'm trying to display the values in a page (index action) using code like this: <% @details.each do |lifeCycle| % <%= debug(lifeCycle)% <%= lifeCycle.lifeCycleId % <%= lifeCycle.eventType % <%= debug(lifeCycle.timeId) % <% end % From the debug I get a result like this: --- !ruby/object:LifeCycle attributes: eventType: Order created_at: "2111359287.23037" timeId: "2455364.89983796" eventId: "98765" updated_at: "2111359287.23037" lifeCycleId: "12345" id: "1" attributes_cache: {} But whenever I try to access the event timeId - i' getting a nil value. This is true if i try to run debug on just that field debug(lifeCycle.timeId), or call a function on it. Is there something obvious I'm missing here?
