• .NET Development Data Access, where to start?

  Hello, I am developing a small application and I am wondering where to store information that I need. After some thought storing the information in XML or in an Access database is probably the best option. Could someone point me in the direction of some resources for opening a connection, getting info and sending info to XML or Access or both Cheers, padraic Hickey Padraic, We've got two choices here I'd recommend, but # 2 if I were you: 1. Use an Access database Go to the MSDN Office Developer Center - Access http://msdn.microsoft.com/office/understanding/access/default.aspx Post your Access relate ...Show All

• SQL Server Mining Access 2003

  I created a  AS 2005 data source to an Access 2003 database on my PC. The connection tests fine, I can browse the data from AS 2005. But when I try to process the mining model, I get a userid & password error. There is no password on the Access database. When I set up the data source, the wizard wanted a userid and password - the default was Admin - and I left the password blank. The connection tested ok. I tried changing the Impersonation settings, but that gives me a deployment error. Any ideas why the model process can't find a connection Is the AS Client and Server on the same machine   Si ...Show All

• Visual Studio Express Editions Integrated Security/Open & Close SQL/Access databases

  This thread is based on an exercise in Rick Dobson's book "Beginning SQL Server 2005 Express..." From p447-453 he goes thru how to set it all up. What doesn't seem to be explained are the following tasks/possibilities that leave me a bit perplexed. (1) If u have an existing project which u want to take advantage of this security/connectivity approach do u have to copy all your code and objects so that they reside within the single Security/Application project If so then that means u need a separate security/connectivity encapsulator for each project. Surely not! But I don't know. If the answer is no, meaning that u can wrap ...Show All

• .NET Development Is there a way in regular expressions matching to ...

  I'm not sure that this is doable, but I sure wish it was. If so, please point me in the right direction. (Also forgive me if this is the wrong forum and point me the right way on that also.) I will be honest up front. I know just enough about regular expressions to be dangerous. OTH What i've got working is great. My goal is to validate a user enter catalog number in a situation where such numbers are like chinese menus. One from column A, one from B etc. When my user printed out all the combinations to see if I did it correctly the legal inputs ran to 600 pages!-( The expressions themselves aren't all that bad and are built from fragm ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. DirectX vs. WPF

  A friend of mine said that Avalon was dropped off and renamed to DirectX 10. Based on the theZBuffer.com, there is no DX10, and from what I know, Avalon has been renamed to WPF. So what's the connection between Avalon, WPF, and DirectX (10 ) Are they sharing the same code, or one's just using another's API Thanks! You are right that Avalon was the codename for WPF (Windows Presentation Foundation). WPF use Direct3D 9 to render a vector based UI. WPF is not dropped as it is one of the three main parts of WinFX. As WPF supports 3D effects you can build 3D games with it but it supports only a limited subset of the functions th ...Show All

• Smart Device Development C# and unmanaged C++ library

  Hi, I would like to know whether I can create a C# dll that makes calls to C++ unmanaged functions in a C++ library file (not a dll file) If yes, how I know about dllimport and marshaling; I want to know whether a simlar procedure exists for .lib files. Needless to say, my lib file is compiled for smart device and I would like to have one managed dll that does not call another unmanaged dll, this is basically why I am interested in .lib. Thanks, Sorry, it is not possible. Your only options for calling unamanged code from managed is PInvoke (which you know) and COM Interop - not libs. Cheers Daniel ...Show All
