• SQL Server Error with for..next loop variable

  I'm setting a variable called ConnectionString_vc in a for..next loop.  The connectionstring property of one of my connections is then set to @[User::ConnectionString_vc] via an expression.  When running the package in a SQL agent job I'm getting the following error in my logs.  I've received this sporadically when running it in debug mode in BIS, but it happens consistently in Agent.  The variable "User::ConnectionString_vc" is already on the read list. A variable may only be added once to either the read lock list or the write lock list. Are you using that variable anywhere else Perhap ...Show All

• Visual Basic VB 2005 Compiler Optimization Discussion

    There's been something percolating in the back of my mind. I come from a computing environment that preceeded windows and the Intel Architecture and instruction set. n comparison to the instruction set that i'm used to, the Intell instruction set looks like a house wreck which may or may not be important to the discussion at hand. Everyone knows that moderators agree on everything and that in moderator space we just stand in love circles and sway back and forth. So when I was discussing a compiler one day, I said I really admired a language which had a seven pass compiler. "Nonsense", was the response, "two will do it." Wi ...Show All

• Visual C++ Migrating an existing MFC application

  I'm investigating different solutions available to migrate our existing MFC application to .Net. At this point I find out that the best way to keep the application working during the migration is using MFC 8.0. I think we should first compile our UI (MFC exe) in Visual Studio 2005, then add /clr and then use .NET class libraries and its user controls to implement new features of our application. The question I have is about the underlying MFC dlls. I mean the business logic layer. Should we compile Dlls of this layer with /clr what are the benefits What is its effect on performance Than ...Show All

• Visual Basic Need Help on Displaying ContextMenuStrip

  I need help displaying a ContextMenuStrip in a ListBox when I right click my mouse. I have been trying but I only get it on left click and the menu appears in my top left hand corner of my screen. (This is for VB.net 2005) If anyone knows how to do this please help, Thanks! Also I have another question about how to get a text to go to the end. Like I have a text box to show raw data of an IRC Server and I would like to try to get it to the end instead of staying at the top. In Visual basic 6 the code for it was: Private Sub txtData_Change() txtData.SelStart = Len(txtData.Text) End Sub   So In vb.net 2005 I tried this cod ...Show All

• Windows Forms Yikes: usercontrol inherits from abstract class

  All was going well until I tried to open the designer window for a user control that inherits from an abstract (MustInherit) class.  The designer won't open because it's trying to instantiate the base class, for whatever reason.  Is there a way around this, is this by design or a bug, is it better in C# or .NET v1.1 I guess I can w ...Show All

• Visual Studio Setup &amp;amp; life cycle

  This is going to be a bit longer ;) I see two kinds of DSLs at this point (and all kinds of shades inbetween): 1) A company builds a DSL and sells it. They come up with a new version every two years. Having the new setup project type is great for that scenario 2) DSLs that evolve rapidly with a project (or many projects). I am going to focus on 2. I see this as follows: Someone builds an app. Sees code patterns that could easily be automated with a DSL. Creates a DSL for a very, very small part of the project. Repeat (ie another pattern is found). Repeat. Repeat. Improve the first DSL a little. Repeat. Repeat. Improve another DSL a little, t ...Show All

• Visual Studio Team System Reference Project dll from Separate Solution

  I have a team project with about 3 solutions.  How do I reference the output of a project in a different solution without duplicating the project Yes, that was the information I was looking for, though certainly not the answer I wanted.  :-( I realize this is V1 beta of TFS, but I hope things like this get addressed for V1.1 or V2.  I'm a single developer shop and I'm running into scalability problems such as this already.  I can't even begin to imagine problems a larger shop would run into.  Thanx, ...Show All

• Visual C# Help me to understand better the interfaces

  Hi i read a bunch of articles on articles.. i know exactly how to amke them.. But i dont understand why should i use them .. or for what are they important.. Why should someone wanna make a interface for something... Please help!!! It's not correct to say " inherit from interface" (except complex case, like inheriting interface from another interface). Interface is implemented . You inherit from class. Sample with balls typically implemented like this: public abstract class Ball { public abstract float Radius { get; } } public class FootBall : Ball { public override float Radius { get { return 10.0; ...Show All
