• .NET Development SQLConnection.GetSchema and ForeignKeys

  Hi I am just getting into retrieving schema info from a SQL Sever 2000 using the GetSchema method on the SQLConnection. My problem is that although I can retrieve the fact that a particular table has a foreign Key of a particular name I can not find away to retrieve the name of the foreign  table. Can someone guide me in the right direction. Thanks in anticipation that there is a solution:-) Similarly, GetSchema("Index") and GetSchema("IndexColumns") don't return information about whether an index is clustered and/or unique. ...Show All

• Software Development for Windows Vista Rasing integrity level from a low level integrity process

  From IE7 (Protected mode) on Vista, i am launching a process (A) which has low level integrity since IE7 runs as low level. Can i launch a process(B) from A with high or medium integrity level My previous comments apply to generic low integrity processes. IE7 actually happens to provide services to handle elevations for its plugins. See http://msdn.microsoft.com/library/default.asp url=/library/en-us/IETechCol/dnwebgen/ProtectedMode.asp There's a section about starting processes from Protected mode. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. tank combat beta 2

  tank combat beta 2 - http://www.threesixbox.com/project/ id=bc37832b3a I used a beta 1 version by Michael Lee at learnxna.com as a springboard so he deserves a lot of the credit. I ported this to beta two and improved the graphics and movement as well as added a scoring system. Still to figure out:   Make the bullets bounce 1-3 times before expiring   Don't let the tanks run each other over   Create a variety of levels with walls that deflect the bullets   Put some delay into bullet firing when very close to opponent to eliminate machine gun effect.  I'm very new to game programming ( I had 4 semesters of C++ and VB in college but it was all windows application stuff) so I welcome ...Show All

• Visual C++ Best approach for IPC...? Confusion about what to use...

  Dear all I have been thinking the last few days of a best way to achieve this task: I have two pieces of software. They are both independent application and are final products.(i cant modify the soure).But they both provide an API listing methods that i might want to use to extend some functionality. What i would like to do is as follows: If i am in PROGRAM A and i click the mouse i would like to transfer the mouse click to PROGRAM B.Or if i drag the mouse in PROGRAM A i would like to do the same event in PROGRAM B and vice versa. The API specifies how to do the clicks and drags in both applications but the problem is how to initiate those functions...... I was doing some work and i can identify the window handles and thought that i can s ...Show All

• Architecture Visual Studio and Modeling

  Hi , Has any one come across Visual Studio 2005 's class syncronization's issues basically it looks like VSTS doesn't support generation of sequential diagrams. For requirements gathering and UML Modeling, If I have to make a choice btw Visual Use Case and Enterprise Architect then which is sufficent enough to integrate with VSTS 2005 and / or does allow to represent the requirements and allow to do the UML for the class and sequence diagram generation. -Paresh Hi Paresh, If i recall correctly, I wrote to you once (perhaps in another forum) that VS 2005's class designer is connected directly to the code, meaning you cannot model a class and then decide to synchronize it (further mor ...Show All

• Visual Studio Team System Cutting off the branch one is sitting on - is it really possible?

  Hi. One of our project administrators removed the "Inherit security settings" on a folder in Source Control, and clicked the "OK" button before adding any groups or users in the "Users and groups" section. No warnings or errors was displayed. Now he's not able to see this folder in the Source Control Explorer - fair enough, as he has no access to that folder. I'm able to view the folder, as I'm a server administrator, so I opened the Security tab and added the "Project Administrators" to "Users and groups" in order to give him the possibility of correcting the error. But trying to do this I get an error stating that I need "ProjectAdminRights" for that folder. Same mes ...Show All

• SQL Server Calculate the values from a underlying table

  I am building a customerlist within the customer sales of a period. I have a dataset with two tables: "customer" and "customer_ledger_entry". In the report I will present the customer number, the customer name and the sales. The problem is the sales value is not available as a field, but I have to calculate this value from the "customer_ledger_entry" table. In this table are several entries (invoices, credit notes, etc.) How to calculate the values from a underlying table Selectis, I must have misunderstood what you were trying to accomplish, I thought you when trying to display values from 2 different tables but I didn’t realize you want to reference the 2 dat ...Show All

  I want to be able to dictate the order in which my components are drawn and updated. However, we are not allowed to change our ComponentCollection, and it has no concept of ordering other than the order in which things are put into it. What's the best way to deal with this Should I create separate components to manage all the drawing and all the updating, and just order the items in there, or am I missing something in the framework You might want to read this , especially the part about Game Components. ...Show All

• Visual C# caching at application start up????

  I am working on my first web app and I implemented caching in my C# classes (BLL). Now while developing the application I noticed that not all data is going to be displayed to the user. Some of the data is being used by the application, for example all the different email messages that can be send out to the users, such as ForgotPassword, WelcomeNewUser etc. My approach is that the data is being cached when the user pulls up the data. Usually I get a subset of data, for example 10 records at a time, and cache them. When I need the data again I check first the existing cache to see if it has been cached and if it has get the data from the cache. Now my problem is with a table like EmailMessages the user is never pulli ...Show All

• Visual C++ Trivial Properties vs. Block Properties vs. Traditional get() set() methods = Compiler Bug!!!

  I already posted this thread but I am not getting any feedback. I would like someone from the C++/CLI development team to take a look at this. I have provided a sample of C++/CLI code and it's equivalent written in C#. This is about as simple a demontration as I can provide so hopefully someone will try this out and at least confirm that this is a compiler bug. I have two classes, class 'A' and class 'B'. Class 'B' derives from class 'A'. They both have the same privately declared (same names and signatures) properties and 'get' and 'set' accessor functions. This is possible because they are PRIVATE. The 'get' and 'set' accessors work fine, the trivial property works fine, but the block property in the derived class causes a compil ...Show All

• SQL Server Could not Authenticate with SQL Server

  Here's my situation and I've spent enough time to troubleshoot. Any help would be appreciated. 1) I have a VB.NET Windows Form Application that uses SQL Server Express 2005 database. 2) The "mdf" file is a part of the application itself. 3) When the application distributed to my clients using Windows XP SP2, the "Click Once" installer automatically installs SQL Server 2005 Express [which is a pre-requisite] and copies this mdf file into the application folder. 4) The authentication mode is "Windows Integrated" The problem is, when the application is launched [while logged in as the local system administrator in a given computer], it is unable to connect to the SQL Server.
