• SQL Server MDAC Roadmap and .mdb files

  I know this isn't SQL server related but this seemed to be the only appropriate forum. I would like to work with Access databases (.mdb files) via (non-managed) C++. At the moment I'm using the ODBC provider for OleDB. However I see from the MDAC " Data Access Technologies Road Map " that this provider is deprecated. The OleDB/ADO alternatives seem to be focussing on SQL server only; I just want a 'local', non-networked desktop system. What technology should I use that isn't deprecated Yours, Peter If you are using C++ and either OLE DB or ODBC then you might want to consider SQL Server 2005 Express Edition ( http://msdn.microsoft.com/sql/express/ ). I'd also recommend looking at C++ ...Show All

• Visual Studio Express Editions Rename project

  How do I rename a project well of course...since those are files - renaming a project is different to renaming files. Renaming a project only renames the project itself. I believe things are still not entirely clear. What exactly do you want to do/achieve I understand you wish to rename a project, and have given steps on how to do so, but it appears that you do not want this Perhaps giving us a further in depth detail will help us provide a better answer to your needs ...Show All

• Visual J# setup program +NET 2 +Microsoft Visual J# Version 2.0 Redistributable Package

  Hi, I am having a small problem, when creating a setup you can specify that setup program will actually download and install.NET framework and J# redistributable prior to installing an application. However, while installing .NET 2 Framework it fails to install redist. for J#. I believe it says it is unavailable or something like that and redirects IE to J# page. Any suggestions I created a dummy project and its working fine for me. Could you please give me some more details of it. 1) Which VS product are you using - Developer Studio 2005 or VS.Net 2005 2) On which OS you have created Setup project 3) On which OS you have implemented/consumed Setup.msi 4) Are y ...Show All

• Software Development for Windows Vista SetStateActivity - set TargetStateName during Execution of Statemachine

  Hi all, I have a statemachine. In several states I can get into a "special" state. From the "special"state I have to go back to the state I came from. Now there is the Statemachine property PreviousStateName available. I wanted to set the Dependencyproperty "TargetStatename" of the SetStateActivity to that PreviousStateName by a codeactivity. But setting the targetstatename of the setStateActivity is only allowed during DesignTime... Now I tried to reflector the SetStateActivity(in order to create my own SetState) but its quite a deal of effort since its got a helper procedure tail in several workflow helperclasses which are internal. Are there already any activities around which fullfill the requirements abov ...Show All

• Software Development for Windows Vista More vista bugs ? How do you determine if UAC is enabled ?

  Hello, Just testing with Vista RC2 (downloading RTM as I write this) and I would like to know if anyone knows how to correctly determine in a c++ program whether UAC is currently enabled on the machine Also when UAC is turned off, and one is not logged in as an administrator, "RunAs" in ShellExecute() no longer seems to allow the execution of a task as a full admin. This seems to apply to Microsoft's own applications too. Try running the task manager (CTRL+Shift+Esc) on a none admin account, with UAC turned off, and then click on the shielded "Show processes from all users" The task manager restarts itself, and nothing else happens. If the shielded button does not work, then why is it shown A jolly poor show IMHO. Jus ...Show All

• Visual Studio Express Editions Creating a Physics Model

  I am fairly new to C# but have been coding for several years now. Basically I am creating a basic physics model so I need some kind of loop to run it in. Using a while loop would probably be a bad idea because the application would starve CPU from the rest of the operating system. I know with directx you create a render loop, I basically need to create a render loop without directx; does anyone know how It depends on your real-time requirements. If tight: starve them all. If not, call Threading.Sleep. Or Application.DoEvents to keep your GUI responsive if you don't spin off a thread to do the job. If light: use a timer. ...Show All
