• Visual C# How to check 2 reference objects for equality?

  For examples sakes i got 2 Table instances, that are created by the same routine thus i know for a fact they are exactly the same. However when using equality checks they always return false indicating the table instances are not the same. I am using the following static methods 'object.equals' and 'object.referenceequals', i also tried the table instance's 'equals' method. How can i implement a conditional check to see if 2 instances of the same type are the same well you shouldnt need to check if the type is the same if you created the same object. you could use the GetType() of the object and see if it is the same type of the object in question. Example: if (objectInstance.GetType().Equals(theOtherO ...Show All

• SQL Server how do I get the value of a DEFAULT

  Hi We have a default defined in our database CREATE DEFAULT [ schema_name . ] default _name AS constant_expression [ ; ] How can I ge the value of the constant using SQL Also - anyone know why this is going to be removed from a future version of SQL - we use it for partitioning with replicated clients (long story) - but every table has one column which is bound to this default. We find it *very* handy. Ta Bruce That shows the default constraints, but not our DEFAULT (terminology so similar but different - I'm confused!) thanks bruce ...Show All

• SQL Server Microsoft Sql Server Embedded Edition Service

  Hello All, Can someone tell me the actual significance of SQL Server Embedded Edition How is it different from SQL Express edition I understood that WSUS 3.0 version uses (installs) the latter when it could not find any SQL 2k or SQL 2k5 other than SP1 release (please see Issue 33 in: http://technet2.microsoft.com/WindowsServer/en/library/94d1385f-4872-4c29-8822-3a4ec5e45ae41033.mspx mfr=true ) on the host machine.

• Visual Studio Team System Add application-tier to an exisinting Database-tier

  Hi I have an existing TFS using two servers. one with SQL used and database tier and another one for application tier. My question is: How can I install the application tier on the server with the existing database tier (I want to later configure it as a warm standby). Installation won't go because it recognises the installed database tier. I do not want to uninstall the database and reinstall them both (db and app). thanks In the installation guide you have instructions for it, under the Dual server installation optios you have another section for continuos server avaliability, chec out this two sections: Checklist: Standby Application-Tier Configuration How to: Configure an Application ...Show All

• Visual C# Before we proceed I really need some protection!

  If I were to make a C# program that contained a sensitive algorithm, how could I protect it I know that C# generates MSIL (this is what has me the most concerned), is there any way to get the compiler to scramble it or some thing The last thing I want is my code decompiled. I probally should have made a native C++ project, but it is so hard to motivate your self to do so when C# is sitting right in front of you. When the compiler declares variables in MSIL does it name them what you call them in C#, or does it assign them more machine like names Any suggestions would be helpful. Not exactly, but the logic will be there, only the names as i write will be crypted. So the name of class-s will be a, b, c, d ...Show All

• Visual Studio Controlling and detecting what elements are droppable on the diagram and other elements

  Hi, I've created my first DSL which can accept DSRef items from the server explorer. To implement I followed some samples which are already described on the forum. In an overriden OnAssociated I bind the DragOver and DragDrop events and check for a CF_DSREF type. This is all working OK and I'm creating business objects, attributes and relations fromt the database metadata. My issue is that I managed to change something in the DSL which prevents business objects being dropped from the toolbox onto the diagram. So I'm looking for leads on which properties control this behaviour and where in the underlying DSL tools framework sources I can debug to get more knowledge of how this is implemented.

• Audio and Video Development Audio-software Development with DirectX 10

  I wish to develop an audio software (like winamp, jet-audio etc) using Direct X 10. Dear experts, what do you suggest about this Should or should not I go with this Please tell in detail regarding your suggestion. Thanks Well, which API you'll want to use probably depends on what exactly your application is going to do. For instance, if you're looking to write an application that does playback of audio files, you could consider using Media Foundation for this. I'll say that this forum is primarily about Media Foundation, which is the new multimedia platform for Windows Vista. So if your application is going to need to run on earlier OSes, you'll probably need to use a legacy platform (like DirectShow), in which case your b ...Show All

• Visual Studio Team System Process Template change

  I want to remove a few workitems I do not use in my process template. For example.  I have no reason to create a "risk" workitem.  I know that if you alter this xml.  And remove the entries for the workitemtype that you don't want created it will work fine for any new project created using this template.  (see xml below). However I don't want to create a new project, we only use one project.   Is there a way I can remove the ability to create certain workitem, ie "risk" in an existing project    It should no longer appear when you right click on workitems and choose "Add work item" from ProcessTemplate.xml <task id="WITs" name="WorkItemType definitions" plugin="Microsoft.Pro ...Show All

• Visual C++ Why I can't complie below code in VS2005

  Because of std::swap function, I can't compile below function. but if I don't specify template parameter, it is compiled very well. I wonder why I can't specify template parameter when I use swap function, but if include <utility> instead of <vector>, I can use std::swap specifing template paramter. I think it's Microsoft STL library bug..., it is needed to fix it. #include <vector> // if I include <utility> I can compile below code. template <class T> class CTest { typedef CTest<T> ThisType; T* m_Array; public: void Swap(ThisType& other) { std::swap<T*>(m_Array, other.m_Array); } }; int _tmain(int argc, _TCHAR* argv[]) { CTest<double> test, test2; test.Swap(test2); ...Show All
