I've used Redgate's .NET Reflector tool to look at the code for DataRowView. The column accessor property looks like this:

<br />
public object this[string property]<br />
    {<br />
        get<br />
        {<br />
            DataColumn column = this.dataView.Table.Columns[property];<br />
            if (column != null)<br />
            {<br />
                return this.Row[column, this.RowVersionDefault];<br />
            }<br />
            if ((this.dataView.Table.DataSet == null) || !this.dataView.Table.DataSet.Relations.Contains(property))<br />
            {<br />
                throw ExceptionBuilder.PropertyNotFound(property, this.dataView.Table.TableName);<br />
            }<br />
            return this.CreateChildView(property);<br />
        }<br />
set {/*elided */}<br />
}<br />

so it looks like you can access the column name property from :

<br />
repRow.DataView.Table.Columns[0].ColumnName<br />

I'd really recommend getting a copy of the tool - I've found it useful in loads of situations. It's available for free here[^].

It definitely isn't definatley

I've just read this message again and think I might have been talking at crossed purposes - I've been looking for a way to access the name of the column rather than the value... To access the column value you'd simply use the accessor method:

<br />
repRow["Surname"].ToString()<br />

This assumes that guarantorBinding.Current is the first line in the collection - is this correct? If not, what sort of object is guarantorBinding? Chances are it will have a 'Rows' collection so you'd access the first row using something like guarantorBinding.Rows[0].

It definitely isn't definatley

Many thanks for your reply.

GuarantorBinding is a DataSet DataTable. The current position may not be at 0, and I want to find the value for a column for the row which is at position 0 without changing the current position.

Hope that makes sense ...

Accessing the row using the indexer won't affect the enumerator (Current is an implementation of the IEnumerable interface) so you can use this without affecting anything the current position.

It definitely isn't definatley

Hi,
In C++ to contact with files we have FILE type but in C# I dont't know how to do that. I can't find any material or document about this problem. Please help me.

Thanks

Look into the System.IO namespace, particularly the classes that begin with File (File, FileInfo, FileStream).

you say that as if you have looked.

I cant image you did a search for anything related to files in c# and found nothing!!!

do you need something specific about the file, or from the file?

Didn't there used to be away in Visual Studio that you could go "forward" or "backward" in your code? If so is it still there in 2005/2008 and how do I find it?

I don't know the exact shortcut (because I remapped it to the alt-left alt-right Eclipse shortcuts), but you can find it under Tools -> Options -> Environment -> Keyboard

- View.NavigateForward
- View.NavigateBackward

I created 6 Windows services in C# as per the requirements and deployed working fine, but we found hanging of server, disconnecting SQL SERVER, IE 6.0 not able to open.

And also we found CPU useage varrying from 0 to 90 percentage, without uniformity.

Is hanging the system, disconnecting sql server and drastic CPU useage are because of 6 Windows Services, if because of windows services, can we control.

what is the solution for smooth running of server.

surely it would depend on what your services do and how much processing they do etc.

Do the services never sleep?

I use a System.Timers.Timer to control my services, generally they cycle every ten to sixty seconds.

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
