[DOTNET] DataSets naive question

Hi all, Should I use a Dataset or a local MS-Access database? The basis for my question: The dataset is touted as an in-memory database: It has schema, data, relations, filtering, sorting, and persistence (through XML serialization). So, if it is "like" a database, why not use "the real thing"?

Re: [DOTNET] DataSets naive question

Thanks, Greg. I undestand this "in memory" issue. However, what I'm thinking is: You are supposed to take the data from a 'big' (say, SQL Server) database, work on it in memory using a Dataset, and then return the modifications. But what if, instead, you take the data, store it in an Access (Jet)

[DOTNET] SV: [DOTNET] DataSets naive question

Yes youre missing the point. Both SQL Server and MS Access and all other databases are for permanent storage, like books in a bookshelf. To read a book you have to take it out of the bookshelf and put in on your desk ("RAM memory"). So whatever database you use you need some form of variables in t

Re: [DOTNET] Passing objects in Session State

I am a little confused. Maybe I am thinking too simply, but on any page you have access to the Page.Session object. Therefore: class MyWebPage : Page { ... if (this.Session.IsNewSession) { this.Session["MyNewObject"] = new foobar(); } Foobar myfoobar = this.Session["MyNewObject"] as foobar

Well for one thing, in your scenario you are creating twice the number of processes and a heck of a lot more necessary code. Your scenario Get SQL Server data Write data to Access DB Get Access data Load into Dataset Manipulate data Save data to Access DB Update data from Access DB to SQL Server

If it's not in the FontFamily list of families then you can't use it. As far as I know this means it will cover all the fonts in the fonts folder. (Although I'm not sure about the ancient font formats - the strange plotter-like fonts and the non-scalable ones. I also don't care...) The interest

OK, so I guess the question is: if fonts are installed but unavailable, does the author of the original question care? Or are only those fonts that can be used interesting? (Would the original question asker please stand up?) -- Ian Griffiths DevelopMentor - Original Message - From: "B

How about this for a singleton: // .NET Singleton sealed class Singleton { private Singleton() {} public static readonly Singleton Instance = new Singleton(); } And it is even threadsafe. This is a good article discussing the singleton pattern: http://msdn.microsoft.com/library/default.

Re: [DOTNET] Fonts

I would assume that any font in the font folder could be used by windows (Please correct if I'm wrong). I would think that if you are writing a custom app could call out the font. Better yet, I would assume that if the font is in the font folder it would be installed? D. Wish .Net makes me Randy.

Thanks for the feedback. Thinking this through I think Access has two advantages over an in-memory DataSet. First, it is persistant. It doesn't go away when the user turns off her computer. Second, data is stored and accessed in very efficient manner (i.e. indexes) which is even more critical whe
