Hi,
I'm developing a .NET CF client application and using web services for data transfer. I'm using SharpZipLib to compress transfered datasets so I know the size of the transfered byte array.
I wonder is there an easy way to determine to complete request size (html headerder, soap envelops and the real data) for a single call. I reall...
I have a FormView (bound to an ObjectDataSource) that contains a CheckBoxList that I'd like to bind to a single property of the underlying object that is an Enum with the FlagsAttribute applied to it. Binding to the SelectedValue property always gives me just the FIRST selected value from the list as the property's value. Anyone know h...
I have a number of extension methods defined in my current project. It is a VB.NET project. I have no problem using these methods inside files that are in the App_Code directory, this is the same place that I defined the methods. However, in my page.aspx.vb code behind page these methods are not showing up. I have tried including the cor...
I don't know how long an action could take and I want to display a progress bar to the user in a dialog box. I've tried using System.Windows.Forms.ProgressBar but it doesn't seem to support it.
An example of what I'd want is the progress bar that windows shows you when it's looking for new drivers on the internet. It's just got three or...
I'm extending (not sure if it's the right word here) a partial Cart class that got generated in Linq to SQL database model.
The business logic is that there can be only one Cart per customer. If a customer doesn't have a cart, it should be created; if a customer has a cart, it should be returned.
Here's what I'm doing:

Hi folks,
i'm not sure this is the best way to do the following code. I'm not sold on a foreach inside another foreach. Could this be done *better** with Linq?
*I understand that better could be either
a) more performant
b) easier to read / more elegant
c) all of the above
NOTE: .NET 3.5 solutions accepted :)
NOTE2: the two IList's ...

In Winforms I could set the ProgressBarStyle of a progress bar to Marqee, and that would have the progress bar incriment on its own without having to be set, for processes where I don't know how long its going to take, and no good way to report back to the UI.
I would like to do the same in WPF, but I can't find a way to pull it off sho...

I'm generating a report via Linq to SQL and displaying it on the website.

Any ideas on how to save it as Excel or .csv ?

I have got an enum which is defined like this:
public enum eRat { A = 0, B=3, C=5, D=8 };
So given value eRat.B, I want to get the next one which is eRat.C
The solution I see is (without range checking)
Array a = Enum.GetValues(typeof(eRat));
int i=0 ;
for (i = 0; i < a.GetLength(); i++)
{
if (a.GetValue(i) == eRat.B)

I've got a bunch of DLL projects that I'm pulling into my application, each contains their own Settings.settings/app.config. When I compile the app and run for debugging, everything works just fine, but come deployment time I can't get my DLLs to read their own settings files.
I've been doing some reading and it has become apparent tha...

I remove an item from the session using Session.Remove(), then redirect to another page. If I click back, then reload, the item is suddenly back in the session. Shouldn't Session.Remove() take it out of the session for good?

I'm working a a project for a new web app. I'm identifying the key points of functionality, and one thing that I clearly don't know how to approach is as follows:
Once per minute the server needs to run a series of calcs on its data, and post new derived summaries.
So in essence what I need is a way to run a server side script once p...
