Dear Sir,
>>If it's your collage project, should you be asking for someone else do you it for you?
I am sorry if you interpreted it like that but its not true. I am new to remoting. More over at my place no books of remoting are availabe. Every body here is living in past vith VB/VC++ 6.0.
Rest, I assure you there is a problem which i am not able to fix. I need just help to fix it. I will make my project myself. Like i have done till date, of course i need help and guidance from experts like you.
Thanks for your concerns,
Regards,
Rahul.

If you're new, than either you shouldn't have chosen it for your project or you should learn it - part of the point of a project.
There are plenty of books available about .NET Remoting that are for beginning and intermediate developers, and contain concepts for advanced developers as well.
See "Microsoft .NET Remoting" from MS Press[^] and/or "Advanced .NET Remoting" from Ingo Rammer[^].

Dear Sir,
I have found the solution to the problem. Now, if you can please assist me to put it right.
Please assist...
it goes like this... Program is not reading web.config file. If it is specified at the click event of buttion like
RemotingConfiguration.Configure(@"C:\Inetpub\wwwroot\RemotingClient\Web.config");
the program works fine. How can i fix it?
1. The Url of the config file is not proper. I have tried all possible combinations but it is not working.
2. If second click is performed, even after restarting the page and server it gives an error that channel is already registered.
Please Assist...
Thanks for your kind help and great Example
Regards,
Rahul.

.NET Remoting does not read the .config file automatically. To do, get the path to the .config file using AppDomain.CurrentDomain.SetupInformation.ConfigurationFile to get the path programmatically. Then call RemotingConfiguration.Configure with the return value of that property.

Hi,
I'd like to write a stealth windows application that logs what files a user downloads. I would like to use the application to perform trend analysis, what files(jpegs, gifs or mpegs etc) a user downloads the most. Using C# I would like to know the logic behind it!
eg. User clicks on a button or href to download file.
My app logs user downloading file from site
Any ideas will be much appreciate it..!

You would essentially be writting a firewall. A low-level application that the .NET Framework is NOT suited for. You'll be P/Invoking ALOT of Win32 API calls yourself.

You could also write a Browser Helpfer Object (BHO). It's an ActiveX control that can sink the connection points in Internet Explorer, similar to how IE toolbars and desk bands work (though no GUI is required).
See Browser Helper Objects: The Browser the Way You Want It[^] for more information.
While you could create a BHO using C# and exposing a CCW (COM-Callable Wrapper), it would be pretty slow with the extra marshaling overhead. I suggest writing one in C/C++ if you know it - it's really not too hard.

The ListView control doesn't natively support alternating colors for ListViewItem's or changing the Header Background color. You would have to ownerdraw the ListView control yourself to get that kind of functionality.
Check into articles on CodeProject here[^] and here[^]. Also on CodeGuru here[^].

Does anyone know how I can get my property that is a member of my Component, so show up in the Dynamic Properties section of the property editor? I want to bind it to the app.config file, and I expect it to appear in the designer so I can bind easily through the IDE... (did I explain that clear enough?)
Thanks!

The following attribute will place FirstName within the Dynamic Properties and then the Advanced section.
private string _name;
[Category("(DynamicProperties)")]
public string FirstName
{
get{return _name;}
set{_name = value;}
}

You should take a look at the classes in the System.ComponentModel namespace for more helpful design-time attributes and more. A good section to read if you're new to design-time extensibility is Enchancing Design-Time Support[^] in the .NET Framework SDK documentation.

Great stuff! Thanks Health and Nick. Yes, I'm new to .NET entirely, and am very impressed with what I'm seeing so far. Thanks for the tips and pointers...

 I have seen a document somewhere I can design the window form shape to be circular, instead of traditional rectangle shape. Can anyone help? I'm thinking of making this round shape for about box. Something unique.
That's in Visual.net C# language. Thanks!

This uses a clipping region that works with all Windows. See the Graphics.Clip property in the .NET Framework SDK.
One Windows 2000 and newer, you can also use alpha blending and transparent colors. For example, you can set the BackColor of many controls to Color.Transparent. You can also use an image with alpha blending in many cases. Again, though, this is only supported on Windows 2000 and newer NT-based OSes.
Another thing you should check out is the RegionMaster Controls[^] on WindowsForms.net. This is written by a Microsoftie, though not supported officially by Microsoft. It was featured in MSDN TV some time back and is very nice. This aleviates the work for you.

Hi,
I basically create a dataset and read in a schema file into the dataset. Then when done saving a record to the dataset I save to file as diffgram. When I come back in and recreate the dataset I need to find a particular record that is in the dataset. I do this with the following
code:
<code>
private void FindTodaysDSRec()
{
string sDate, sRecFind;
DateTime dDate = DateTime.Now;
dDate = dDate.AddDays(-1);
// sDate = dDate.ToString("d", DateTimeFormatInfo.InvariantInfo);
sDate = @"12/1/2003";
sRecFind = "MR_Date = " + sDate ;
nRow2 = dsDiff.Tables["MN"].Select(sRecFind);
}
</code>
The record I am looking for exists in dataset but I get a nullrefexception on the select statement.
Here is what the MR_Date is represented as in the schema file:
<code>
<xs:element name="MR_Date" type="xs:dateTime" msdata:AutoIncrement="false" />
</code>
Here is what is in the diffgram:
<b><small>
<Table diffgr:id="Table1" msdata:rowOrder="0"><MR_ID>110</MR_ID><MR_Date>2003-12-01T00:00:00.0000000-05:00<MR_Date>
</small></b>
The sDate statement in the select looks like this:
sDate = "MR_Date = 12/1/2003"
So what am I doing wrong with my select clause in code above?
Thanks,
JJ

There is no table called "MN", so your dsDiff.Tables["MN"] is returning null. This is the kind of check you should make before calling methods on an object when you're not sure if you'll get an instance or not.
When you read-in your DiffGram, make sure you read the XML Schema first (or just use a typed DataSet) and use ReadXml("somefile.xml", XmlReadMode.DiffGram) since the file is formatted differently than how a DataSet is serialized normally.
Also, make sure you read the schema before writing your DiffGram. I noticed that the DiffGram table ID is "Table1". The same schema must also be used for both WriteXml and ReadXml.

Hi Heath,
I did what you said, read in the schema first then the xml diffgram file. This goes smoothly but as soon as I hit new row on dataset I get the nullrefexception. I named the table statement as "Table1" too. Here's my schema file and xml file maybe u can see something I don't:

This is the line it errors on :

No, actually you called your DataSet "Table1", which I noticed in your previous post. Your DataTable is named "Table". The DataSet element is the root node of your DataSet, the child nodes is/are the DataTable(s), and their children are the fields in a row of the table.
So, dsDiff.Tables["Table"].NewRow(); would work, but you really should name your DataSet and DataTable appropriately according to your needs.

Hi all,
This is driving me crazy. I have a double variable that has taken a value very close to zero. I try to put the value on the console as
double noiseMean;
Console.WriteLine(noiseMean);
It displays the value in the scientific notation. How can I tell it to display it as the decimal notation. I tried using noiseMean.ToString(), but it always frmats it in the same notation.
Thanks,
Pankaj
Without struggle, there is no progress
