In Framework 2.0 String has a new more convenient method that enables you to simultaneously test whether a String is a null reference or its value is Empty. - IsNullOrEmpty.

Hi, I’ve managed to build and deploy Web Service project using Team Build. In order to do it I had to manually create Target to launch AspNetCompiler task in the build.proj file

Team Foundation Build is built on MSBuild. Check out the MSBuild Reference in the .NET Framework SDK

Hi, check out log4net.

log4net is a tool to help the programmer output log statements to a variety of output targets. log4net is a port of the excellent log4j framework to the .NET runtime.

I use it in all my "layers" including the Web Service. It's great.

Steve Jobs: Similarities? Similarities? Try theft.

I' ve heard that Visual Studio 2005 RC was dropped on MSDN today and will also be handed out to all of the PDC ’05 attendees.

Is it true?

How is it bound to a DataView? This is how I'm binding:

Me.dgProducts.DataSource = Me.dsPhotographers
Me.dgProducts.DataMember = "Photographers.PhtgToProducts"

DataSource property can accept only objects that implement IList and IListSource interfaces.
DataTable delegates this implementation to DataTable.DefaultView. That’s why, when you set DataSource to DataTable (or DataSet and DataMember to “TableName”) DataGrid is actually working with DataView.

Read Rico Mariani's Tracking down managed memory leaks (how to find a GC leak)

How do you upload large file? Do you use streaming for this? Otherwise when 10 users start simultaneously uploading a file, say 100 MB – ASP.NET will consume ~1GB of RAM.

I think that the problem lies in that how you do your REFRESH.

When you Do Refresh() on the CurrencyManager it forces repopulation of the bound controls, thus loosing the current selection. – So don’t do this.

It doesn’t matter who is the vendor of the Grid -  Microsoft, DevExpress or Infragistics all of them will behave the same way.

In your case your Grid is bound to DataView (Which implements IBindableList interface).

The IBindableList interface declares the ListChanged event which is used by the Grid  to update itself when bound data is changed.
ListChanged event can be raised with different ListChangedType as argument. When ListChangedType is set to Reset – The Grid looses its current selection and selects the first row.

CurrencyManager.Refresh()
{
    //some code
    RaiseListChanged(new ListChangedEventArgs(ListChangedType.Reset, -1));
}

I hope this helps you.

I personally I never bind a dataset to a grid. I always create custom collections that support ITypedList and IBindableList interfaces.
