This would be better asked and answered by Dundas. There may not be many people here who have the Dundas library.
1) Surely this can be answered by looking at the Dundas website where they have some sample graphs with are in 3D 
2) If it is at all possible then there will be in all likely hood samples in either the documentation or on the website.
PS, I do know this is possible but seeing this can be answered by some simple research I'm not going to bother doing it for you when you have the documentation at your fingertips and I dont.

how could i iterate in nested child node of a xml data.i have given the xml data below which is stored in my xml file.
now i want to write a function which will read all the child node under transaction node.suppose there are 3 child node under
/P2DXML/Sender/Recipient/Document[@Transactions='3']/Transaction node.
in a loop i want to read value from those child node.when read will be complete the control will go out of scope.
in my case Document[@Transactions='3' so only child node related to this will be read.
when Document[@Transactions='4' then only child node related to this will be read.if my question is clear then pls give me the answer with sample code.

You could load the Xml file into a XmlDocument and use the its SelectNodes method to select the nodes you want. The method returns a collection of selected nodes over which you can iterate and retrieve the wanted values.

Hello gurus,
I'd like to know how I can get connected to the default instance of SQL Server with user login?
Where can I find a code snipet that shows how to do that with Windows authentication and SQL Server authentication?
Best regards.
Fred.

By just specifying the machine name, without any instance part.
You can find lots of examples of connection strings for SQL Server here: http://www.connectionstrings.com/?carrier=sqlserver[^]
|
|
|
|
|
Also, if you just want some examples related to your local databases you could look at the connection string that is located in the properties dialog when you select a database server in the server viewer section of VS2005.

This should get you started.
try<br />
{<br />
SqlConnection connection = new SqlConnection("server=localhost; database=yourdb; user=yourusername; password=yourpassword);<br />
connection.Open();<br />
}<br />
catch (SQLExcepton SqlE)<br />
{<br />
//Do you exception handling here<br />
connection.Close();<br />
}
Remember, you need to include the System.Data.Sql namespace for this

Hi experts!
I trying to write a program to read a byte[] from IrDA port.
The IrDA device is onboard (laptop), and in the BIOS this device uses: COM2, but, using the component SerialPort from .NET 2.0, using the COM2 and invoking the method Open() i retrieve a exception: COM2 doesn't exist.
This device is correctly installed and working with windows. I tried add a new COM port, using same IRQ from IrDA, but, this conflicted with IrDA device 
How i can use my IrDA device in .NET 2.0?
Thanks in advance
|
|
|
|
|
How do you open the port?
|
|
|
|
|
I add a SerialPort component in the form, with name: serialPort1
and in the code:
serialPort1.PortName = "COM2";<br />
serialPort1.Open();<br />
The exception says the com2 port doesn't exist.
It´s wrong?
|
|
|
|
|
No i think that's ok..
Take a look at the Infrared Device in the DeviceManager.. maybe you need to configure it when you want to use it as comPort under windows
|
|
|
|
|
Does Hyperterminal see the port? If not then neither can .NET. Another possibility would have been if the com port used by the IrDA does not begin with COM, there's a retarded check in the Open method which checks to see if the port name begins with COM!  At least MS are going to remove this check for the next release thanks to my comment :->
|
|
|
|
|
No, the COM2 don´t appears in the HyperTerminal, but, the IrDA device to file transfer with windows works perfect.
How i know whats name of my port?
|
|
|
|
|
If Hyperterminal can't see it then it's almost guaranteed that it's not operating as a standard Windows COM port. It's probably got a proprietry driver, check through the documentation to see if there's an SDK or something like it available to talk to the com port.
Alternatively see if you can find out which library or executable is being used for the transferring and look with depends.exe to see which library it's calling to talk to the IrDA port.
|
|
|
|
|
First of all it would be a good idea to check all ports on your computer first. I use it like this.
public enum PortAvailabillity
{
Available, InUse
}
public static Dictionary<int, PortAvailabillity> GetPorts()
{
string[] availablePorts = SerialPort.GetPortNames();
Dictionary<int, PortAvailabillity> portStatus = new Dictionary<int,PortAvailabillity>();
foreach (string s in availablePorts)
{
int number = int.Parse(s[s.Length - 1].ToString());
try
{
SerialPort p = new SerialPort(s);
if (!p.IsOpen)
portStatus.Add(number, PortAvailabillity.Available);
else
portStatus.Add(number, PortAvailabillity.InUse);
}
catch (IOException err )
{
#if DEBUG
Console.WriteLine("Error getting port: " + err.ToString());
#endif
}
}
return portStatus;
}
Also you might want to set some more parameters when opening the port (baudrate and such). Always make sure no other program is using the port when you try this.

Thanks! I try this, and, later i write the result.

I've extended the PictureBox control to create my own user control. Now I want to capture the OnMouseWheel. I've done this many times, and it's usually enough to override like this
protected override void OnMouseWheel(MouseEventArgs e) . Unfortunately the overidden method is never called when I turn my mousewheel. I've also tried tying the MouseWheel even to my own method. Weird enough, this isn't called either... Could this be related to the parent control the box is placed in? Any suggestions?

You might try creating a user control that you know has the OnMouseWheel event enabled. Another option would be to inherit from the picturebox and override its WndProc with information related to the mouse wheel.

The picture box should have this event enabled. I've tried the following and found it to be working: The form is placed within a SplitContainer control. Since I was guessing it might be the parent container that was the problem, I tried tying my method to SplitContainer.Panel1.MouseWheel event first. When this wasn't working, I tied it to SplitContainer.MouseWheel. This actually works. This seems very strange because I've always thought that events were passed from the toplevel container on to the back. The solution isn't very charming, since this means the control I made will have to be hooked differently to it's parent controls, depending on the type of parent it's placed In.
Overriding its WndProc seems like a good idea, it's just that I have no idea of how to do this. If you can give me a pointer that would be very welcome, it's almost weekend for me and I don't feel like starting it with leaving an annoying problem like this unsolved

I know it's 4 years too late, but I ran across this post while looking for information on the Delta values in the MouseEventArgs passed to OnMouseWheel.
The reason controls like PictureBox don't fire that event is because it doesn't have focus. An easy fix should be to override OnMouseEnter and calling the control's Focus() method. You may also need to call your control's SetStyle method and give it ControlStyles.Selectable in it's contructor.
It's probably way too late, but I hope that helps anyway.

Was surprised to see a reply to a 4 year old question that I didn't remember I asked in my inbox .
Thanks for the answer. Perhaps the problem has been haunting my subconsciousness for 4 years and is finally at peace . More likely I found a way around it back then though. Still; others may find your answer very useful, thanks again.

SqlCommand cm = new SqlCommand("select dashboardid from dashboardlogin where (loginname = 'hina') AND (loginpswd = 'shaikh')", conn);
int i = Convert.ToInt32(cm.ExecuteScalar());
i have this query working properly,but it gives dashboardid of only loginname=hina.
but i want dashboardid of that person who logs in the system(this code is on login form),whoever logs in the system,his dashboardid must be got in variable 'i'.
what must i do to change my query for such result?
thank you.
nekshan.
