Having two projects: one is a class library (a .dll assembly) and the other is a GUI (.exe) using the class library. In the class library, I've added two .settings files (which automatically adds the app.config file to the project) using all "application" settings. When I compile the project I effectively get the MyLib.dll.config file i...
Hi, We are developing a project using asp.net 3.5 and sql server 2008. I know a bit of xml like creating, loading, adding elements to xml file. I was not exposed to XML Scema, XSLT and XPath kind of stuff. And now there is LINQ to XML and LINQ to SQL also. Could anyone please provide me some good links to learn complete XML for using...
I got to load some data out of a db4o database which takes 1 or 2 seconds at the startup of my app, the rest has to wait because first of all the data has to be loaded. doing this in an own thread would mean that the rest has to wait for the thread-finishing. I'd like to do a splash screen or something during the data is loaded for what ...
Within an ASP.NET application, I'd like to serialize a collection of plain-old-CLR-objects (POCO) to a JSON string, which will then be sent down to the client as part of a web response. Is there a light-weight C# library that does this? ...

Hi all, I've got a .net 3.5 website that calls thousands of different stored procs using Microsoft.Practices.EnterpriseLibrary. We have been getting alot of timeouts and after some playing and testing the use of (nolock) on the end of the table join in stored procs works real well and reduces the timeouts. I want to now do this to al...

So I'm extremely new to Linq in .Net 3.5 and have a question. I use to use a custom class that would handle the following results from a store procedure: Set 1: ID Name Age Set 2: ID Address City Set 3: ID Product Price With my custom class, I would have received back from the database a single DataSet with 3 DataTables inside of it...
Let's say I'm in OU=Groups,DC=contaco,DC=com,ct I can find all the groups in a sub OU, but the only way to find all of the groups user 'bobdole' belongs to is for me to look at each group and see if he is in the 'member' field. Unfortunately, when I look at user 'bobdole', I don't see a memberOf field that has all of these lists, he...
I am working in a .NET 2.0, recently upgraded to .NET 3.5 environment (VS2008, VB.NET) on an existing ASP.NET website project. I am able to generate a Linq-to-SQL Class (also called a DataContext?) in the App Code folder, drag over tables from an active connection, and save it. Let's call it MyDB. When I go to the code-behind file for my...
Is the directorysearcher findall results method capped at 5000 results even if pagesize is set to greater. It really seems to be, because no matter what I get exactly 5000 results. This is C# ...

I've exhausted all the possible causes I can think of. Scenar...

Quick WPF question - on Win 7 (and I assume Vista) in WPF, the default progress bar does a nice little glowing "whoosh"-y animation. I'm showing progress of about 48 things on one screen, and it's a tad overwhelming to have all of these things whooshing on you - can you disable just these animations without affecting the rest of the def...
We have an ASP.NET application that we recently migrated onto a new server with IIS7 and .NET 3.5. In this new environment, some users that are on IE (6, 7, or 8) are experiencing bizarre intermittent problems with postback not working on ASP.NET buttons. (you click the button and nothing happens) The issue happens sporadically. Someti...
In the olden days of the DataSet (and related objects), the in-memory representations of the data objects--DataRow and DataRowView--supported transactional edits through BeginEdit, EndEdit, and CancelEdit. Having both in place allowed more than simply being able to "undo" changes made to an object and reverting it back to its retrieved (...
Let's say I have foreach(int x in xs[]) // xs is an array of int { x++; } Each time through the foreach is independent of the others. Is there a quick way to instruct the CLR to do each on a seperate thread or speed it up by natively parallelising it? Maybe it already knows to do this. I know you I could create threads and start t...
