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
pls reply
regards

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

hi all,
I am doing a database Application using C# and SQL Server 2000.
my application is always running (24hours)..
while running the application,the sql server stop and connected.
after that the application generate error "GENERAL NETWORK ERROR..CONTACT YOUR DOCUMENTATION"
..
Can any ones please help me to solve the problem.?
thanks in advance..

Hi!
This info is too sparse to provide true help. But if I understand your request correctly, the SQLServer cannot be accessed after a while, correct?
The "GENERAL NETWORK ERROR" is in your app when you try to query the SQL Server?
If it's not happening immediately it sounds like a ressource leak.
Make sure you free/dispose of any connections you create after you don't need them anymore.

I create 2 usercontrols: one is parent control that has a collection of child control. Both controls are inherited from panel. The problem is if i add child control into the parent control by using EditorAttribute(typeof(System.ComponentModel.Design.CollectionEditor), typeof(System.Drawing.Design.UITypeEditor)), everything looks fine, and I got both parent control and all child controls variable on the code at design-time.
However, if i try to add child control into the parent control myself by using IList.Add method or even Add method (the same method that the CollectionEditor call), it get problems: 1) The design view looks ugly and 2) the child controls variable doesn't appear on code. I don't know how the CollectionEditor create a new instance of the child control and add it to the parent control Anyone please help !!!
PS. For some reason, I need the child controls are created properly on the code.

Does some of you could tell me what's the function of the codes below:
Thanks!
void DisplayShape(bool Light)
{
HPEN hNPen,hOPen;
HBRUSH hOldBrush,hNewBrush;
COLORREF cfill;
if (Light)
{
if (cluminance == 3) return;
cluminance = 3;
cfill=RGB(0,255,0);
}
else
switch(cluminance)
{
case 3: {cluminance--; cfill=RGB(64,255,64); break;}
case 2: {cluminance--; cfill=RGB(128,255,128); break;}
case 1: {cluminance--; cfill=RGB(192,255,192); break;}
default: cfill=RGB(255,255,255);
}
hdc = GetDC(hWndG);
hNPen=CreatePen(PS_SOLID,1,RGB(0,0,0));
hOPen=(HPEN)SelectObject(hdc,hNPen);
hNewBrush=CreateSolidBrush(cfill);
hOldBrush=(HBRUSH)SelectObject(hdc,hNewBrush);
Ellipse(hdc,393,235,443,285);
DeleteObject(SelectObject(hdc,hOPen));
DeleteObject(SelectObject(hdc,hOldBrush));
ReleaseDC(hWndG,hdc);
}

It's C Code. It draws an Ellipse, and every time it is called, the colour changes. It fades up to white, but not in greyscale, the green component is always 255.

i'm working on an existing VC6 application which has a plugin architecture supporting dlls which export and accept pure virtual inteface pointers. ie after loading the dll, the exe calls an exported C function on the dll which returns a pointer to a PVI. the exe then calls methods on the pPVI somtimes passing back a pointer to another PVI for the dll to manipulate.
now, this is trivial using traditional c++ and i've done it many times but more recently people writing the plugins has asked to use c#, VB.NET and other more 'modern' languages. the trouble is that i've very little experience of .NET programming and the issues around allowing managed and unmanaged code to communicate. and the more i google the less clear it becomes.
any suggestions for further reading matter or urls to sample code would be sincerely appeciated.

how can i show the icon of my application on system tray bar when windows start up?
Thanks
|
|
|
|
|
Two different questions:
1) Icon in system tray: System.Windows.Forms.NotifyIcon is the class (and sample) you want.
2) Running on windows start: I don't know of any API for this but adding a registry key for your application will do:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Run
String Key: AppName
Value: Full Path to Exe
|
|
|
|
|
for the second answer:
how can i create a registry key during setup of my application?
on the value "Full Path to Exe", how can know it (and set it on setup time) if the user during the setup chooses a custom directory on its computer?
|
|
|
|
|
If you're using an MSI-type installer project in Visual Studio, you can add registry keys via the registry view of said project.
