If you're using a VS.NET Setup project you can easily add registry keys during install.
In order to set a registry key value to the installation location just set its value to "[TARGETDIR]". Windows Installer will replace [TARGETDIR] with the path the user chose during installation.
Hope this helps,

Hi All,
Is there any special data type in C# to store large amount of data?
Thanks in advance…

Arrays, Collections, HashTables, ... What works best depends on what your storing and how you want to access it.

Hi All,
I am developing a Wireless Network monitoring tool, I have tried importing CreateFile and DeviceIoControl. But its not working for me. I need all wireless details such as SSID,BSSIList,Signalstrength etc.. I have even tried WMI. I think the reason for failure of these two methods is incorrect specification of Name of the device. Is there any namespace, classes in C# to get this done can anyone help me its very urgent.
Thanks in advance,
Mohan

None at all. WMI doesn't have any classes that expose this either. You'r best bet is a third party library. But be warned, not evey wireless card is capable of doing this. You might want to checkout AirSnare for some library hints.

When you start VS, you get the project list with the recent edited projects. I wonder why the date of edit is the date of project creation all the time. I need the last date of modification.
Has anybody an answer for this problem. Thank you !

That's the main problem. VS takes the date of the *.sln file, not the other one, but I didn't found a way to change/update the *.sln file yet.

Thank you! It's the saving option in the project explorer by clicking the context menu.

Correct me if I'm wrong but the xmldoc.DocumentElement.LastChild would return farm-cfg since the only elements in the xml doc are root and farm-cfg. If this is the case then wouldn't you want to use InsertAfter if you are trying to get the element to insert after farm-cfg?

hi,
I tried using InsertAfter it produces like the result
<?xml version="1.0" encoding="UTF-8"?>
<root>
<farm-config>
<farm name="dev1">
<connection address="localhost" user="root" selectedConnection="1" password="ram">
<lastJob>Copy-All</lastJob>
<lastConnection startdate="2005-05-10" starttime="12:43:23" enddate="2005-05-10" endtime="12:58:32" />
<state>1</state>
</connection>
</farm>
<farm />
</farm-config>
</root>
private void button6_Click_1(object sender, System.EventArgs e)
{
XmlDocument xmldoc = new XmlDocument();
xmldoc.Load("c:/farm-config.xml");
XmlElement farmelement = xmldoc.CreateElement("farm");
xmldoc.DocumentElement.InsertAfter(farmelement,xmldoc.DocumentElement.LastChild);
FileStream fsxml = new FileStream("c:/farm-config.xml",FileMode.Truncate,FileAccess.Write,FileShare.ReadWrite);
// XML Document Saved
xmldoc.Save(fsxml);
}
I need to insert after farm node

XmlElement 's have a PrependChild Option that add the node as the first child, so:
<br />
XmlElement farmelement = xmldoc.CreateElement("farm");<br />
xmldoc.DocumentElement["farm-config"].PrependChild(farmelement);<br />

I have gone back to the original synchronous client/server code, however keeping the BeginAccept and EndAccept in order to alleviate the need for a keep alive. I have now run into a final problem being Encoding and streaming.
1) What would be the best Encoding for sending String messages but also files? (Is there 1 encoding that could handle both?) I have had success just opening a file, converting to UTF8, converting back to Default, then writing to another file, but somewhere along the line my client/server code muffles the data.
2) Should I use the socket stream or the socket directly for sending/receiving? Is there any real difference (IE socket.Send(..) streamWriter.Write(..)) Currently I'm using a mixture of both and I don't think that it is good coding.
Thanks in advance.

We have developed a framework lib in C# that will be used by many of our Apps. For tracing purpose we use .Net reflection and log all the Class elements as the messages flow through various layers of each assambly. But we are unhappy with this generic logic because we end up logging a lot of class members that are needless to be logged.
Can we use custom attributes for overcoming the problem? The message classes will dictate which all class members should become a part of the trace logs.
Will be grateful for anyone who can give suggestions. Thanks.
Regards,
Senthil.

Can on use "transforming" and "stretching" to copy a part of one picture to another picture object.
Thanks

You can use Graphics.DrawImage to draw part of one image onto another.
Just use:
Graphics g1 = Graphics.FromImage(destinationImage);
g1.DrawImage(sourceImage, you can specify source coordinates and destinartion coordiates here just lookup the many overload for DrawImage);
g1.Dispose();

Thanks for that
When I try that code i.e.
_____________________________________________________________________________
Graphics g1 = Graphics.FromImage(viewer1.Image);
g1.DrawImage(dxfdefaultBox.Image, new Rectangle(1,1,400,300),new Rectangle(1,1,1000,1000),GraphicsUnit.Pixel);
g1.Dispose();
_____________________________________________________________________________
I get a "An unhandled exception of type 'System.ArgumentNullException' occurred in system.drawing.dll".
viewer1.Image is stated as <undefined value="">
viewer1 does exist as a pictureBox on the form, and I can write directly to it through a device context -do you have any idea as to why it would appear as a null item in this use ?
Thanks
