• Visual Studio Team System Active Directory and NT4 mix

  Hi, I would like to evaluate the trial edition of TFS, but reading through the installation instructions, it does not support running on an NT4 domain. At present, I have a 2003 server build to install the software on. Unfortunately, My area is stuck on an NT4 domain for the forseeable future, so I want to know what my options are. The following three options spring to mind, but are they workable/supported Note: I'm not a network specialist, so don't know vast amounts about AD / NT4 so some of what I suggest may be rubbish!! I could set the TFS machine up as a domain controller running Active Directory and have it's own domain for TFS, then set up a two way trust between that domain and the NT4 domain that controils the user ...Show All

• .NET Development relationship between tables error

  I get an error while using the dataset designer: I tried to change an already existing relationship between two tables in database on the dataset designer by enforcing cascade delete and update on their relationship. Then i fired delete on the parent table from creating the datatableadpater.delete(). It gave me error The DELETE statement conflicted with the REFERENCE constraint "FK_Products_Categories". The conflict occurred in database "Northwind", table "dbo.Products", column 'CategoryID'. The statement has been terminated. If we can't change any relationship, what is the use of giving relation option in the toolbox.Is it to create a new realtion between two tables and persist that in d ...Show All

• .NET Development Can different datasets with different fieldnames be de-serialized into a class??

• .NET Development coarse exception granularity

  I'm struggling with what I perceive to be a very coarse level of exception definition in the framework. Even though my example is related to a database, I think it's probably more appropriately asked here, since I think the issue is wider than ADO. If not, I'll repost in the appropriate forum. Doing the following, the same exception is thrown, though the error is actually two very distinct things. dim sSql as string = "" dim DS as DataSet dim adaptor as OleDbAdaptor = new OleDbAdaptor(sSql, dbConnection) adaptor.Fill(DS) throws System.Data.OleDb.OleDbException, with a message that says " Command text was not set for the command object." However, sSql = "select * from foo" where table foo d ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Texture alpha channel problem

  Is there a way to apply 2 alpha textures to a single polygon (with one draw call) What I mean is: I have GUI interface in my application, where everything is a textured quad. When I render a sprite (textured quad that has its own alpha channel) inside a "window" I need to clip it to the window edges (irregular boundaries). I already use SCISSORTEST to make simple rectangular clipping possible, but would like to be able to do something similar to Macromedia Flash's mask object. Ideally I'd like to have two alpha channels that would have a cumulative effect, and probably two sets of u/v coordinates as well. What's the best way to do this -nagual This section from the documentation should help y ...Show All

• Visual Studio Context Sensitive Help Isn't

  Hi, I'm using VS 2005 8.0.50727.42 I am editing C/C++ code and highlight any function from the CLR. i.e. "remove" Intellisense correctly identifies the matching function declarations from stdio.h But if I press F1 I get directed to hundreds of pages of C#/Web development/SQL help. I really just want a "man page" for the function. I've tried disabling all the non-C/C++ options on the search page options but all the unrelated help is still shown. Any ideas on how to restrict help to only the CLR help pages Thanks, Steve Hi, Just an update.

• Smart Device Development Enabling num Lock programatically

  I am writing a program for a PocketPC that has a built-in keyboard using eVC, and I was wondering if there was a way to activate the number/symbol lock key programatically As it is, the user has to push the orange key on the keyboard twice to enable the locking feature, I would prefer to be able to enable it in my program so all the user has to do is type the numbers.

• Windows Forms Application Resizing Slooowwly

  Hi, I've got an application that contains quite a few controls. For some reason it resizes very slowly and paints all different parts at different rates so you see elements being repositioned seperately which looks pretty bad. There are a few user controls overlayed but only one is set to visible at a time. I've made sure that there is nothing happening on the resize event using up processing power. It acts like it's just got too many controls to rezise at once, but it doesn't seem like it should be. Anyone experienced this ...Show All
