The Stop method sets Enabled to false. If the Elapsed event is still getting fired, then perhaps your interval is too quick. To get the user-defined double-click time, see SystemInformation.DoubleClickTime. You should always use what information you can from the OS in relation to things like this, especially when honoring user preferences (otherwise they tend to get upset).

I am trying to access a Solaris Unix box from .Net windows form application using sockets or tcpclient classes. I need to send and execute some type of command script that can disable and enable ip/ports on the unix box.
I am not use to the unix environment, therefore I may be doing this totally wrong. If anyone has any code already to share with me that would be great!!
The problem is reading data from a Solaris Unix box. I can get connected to the IP and Port, I can also write to it, but when I read from it nothing happens. No error is produced, no timeout is produced, it just hangs there.
If I Telnet into the same IP I get a login screen. Could this be the hang up? Should I be passing a login and password first?
Below is my code that I am using:
IPAddress myIP = IPAddress.Parse(strIP);
string sszPort = strPORT;
int alPortt = System.Convert.ToInt16 (sszPort,10);
TcpClient Telnet = new TcpClient();
try
{
Telnet.Connect(myIP, alPortt);
Stream TelnetStream = Telnet.GetStream();
if(TelnetStream.CanRead & TelnetStream.CanWrite)
{
MessageBox.Show ("Can Read and Write");
byte[] sendBytes = System.Text.Encoding.ASCII.GetBytes("USER <username>\r\n");
TelnetStream.Write(sendBytes, 0, sendBytes.Length);
byte[] bytes = new byte[Telnet.ReceiveBufferSize];
TelnetStream.Read(bytes, 0, bytes.Length);
returndata = Encoding.ASCII.GetString(bytes);
MessageBox.Show("This is what the host returned to you: " + returndata);
}
else
{
MessageBox.Show("Cannot Read");
}
catch(Exception ee)
{
string excepstr = ee.Message;
}
Telnet.Close();

Off hand, I can tell you that telnet uses the default port 23. You seem to be using 10. So, telnet'ing into the box isn't a valid test if you don't specify a port. Instead, try "telnet machinename 10" on Windows. Trying typing your data directly and see what's happening then.

Hi, how do u change the color of the row in datagrid according to their sort.
(sorted by Proj)
Proj Activity
yesh hihi <== this row will be red
yesh byebye <== this row will be red
yesh hoho <== this row will be red
lolo hihi <== this row will be white
lala byebye <== this row will be red
lala byebye <== this row will be red
(sorted by Activity)
Proj Activity
yesh hihi <== this row will be red
hihi hihi <== this row will be red
lolo hihi <== this row will be red
lala byebye <== this row will be white
lolo lalala <== this row will be red
yesh lalala <== this row will be red
this is a sample where there is more columns, rows and values.
Thank you.

I’m a bit of a nubie and looking for some advice, the code bellow works but looks like a bit of a hack. I know it's a 'WebMethod' its general enough. My concerns lie with the 'Populate product' section toward the bottom.
[WebMethod]<br />
public Product GetProductById(int Id)<br />
{<br />
#region oleDbQueery<br />
OleDbDataAdapter myAdapter = new OleDbDataAdapter();<br />
OleDbCommand myCommand = new OleDbCommand("ProductByIdQueery", oleDbConnection1);<br />
myCommand.CommandType = CommandType.StoredProcedure;<br />
OleDbParameter parameterid = new OleDbParameter("Id",OleDbType.Integer);<br />
parameterid.Value = Id;<br />
myCommand.Parameters.Add(parameterid);<br />
myAdapter.SelectCommand = oleDbSelectCommand1;<br />
myAdapter.SelectCommand = myCommand;<br />
#endregion<br />
DataSet ds = new DataSet();<br />
oleDbConnection1.Open();<br />
myAdapter.Fill(ds);<br />
oleDbConnection1.Close();<br />
Product myProduct = new Product();<br />
myProduct.Id = Int32.Parse(ds.Tables[0].Rows[0]["Id"].ToString());<br />
myProduct.Category = Int32.Parse(ds.Tables[0].Rows[0]["Category"].ToString());<br />
myProduct.ShortTitle = ds.Tables[0].Rows[0]["ShortTitle"].ToString();<br />
myProduct.FullTitle = ds.Tables[0].Rows[0]["FullTitle"].ToString();<br />
myProduct.Price = double.Parse(ds.Tables[0].Rows[0]["Price"].ToString());<br />
myProduct.CurrentQuantity = Int32.Parse(ds.Tables[0].Rows[0]["CurrentQuantity"].ToString());<br />
return myProduct;<br />
}
Sorry for the long snippit. My passed in 'Id' would refer to a unique db key so the dataSet 'should' only ever contain one row.
Do I have to go via a dataSet to populate myProduct object?
All comments greatly welcomed.

You can use a DataTable instead of a DataSet.
The DataAdapter.Fill() method works with a DataTable object.
Free your mind...

Try a DataReader.

I'm writing a control program that will require a lot of screen real estate to interact with the user. One thought I had on how to do this was to use a dual output display adapter and two monitors. I would then create forms that would present specific information on each monitor. My question is how to control which of the two monitors the form is drawn on?

I would recommend looking into documentation for the following keywords:
GetSystemMetrics();
SM_CMONITORS;
SM_XVIRTUALSCREEN;
SM_YVIRTUALSCREEN;
SM_CXVIRTUALSCREEN
SM_CYVIRTUALSCREEN

Or, since this is the C# forum, see the System.Windows.Forms.SystemInformation class, which includes several properties that wrap such information in a managed class.

Seeing that the others are throwing u off track, have a look at System.Windows.Forms.Screen

Seen on my Campus BBS: Linux is free...coz no-one wants to pay for it.

Hello all,
I have to set certain values in a datacell based on its orginial value. So 0 stands for Ended, and 1 stands for in progress. For whatever the reason, Im having a difficult time changing the text of a cell in my datagrid. Im sure im doing something stupid, whats wrong with this picture?
DataGridCell oCell;
for(int k = 0; k <= gridEvent.VisibleRowCount; k++)
{
oCell = new DataGridCell(k, 4);
if(gridEvent[oCell].ToString() == "1")
{
gridEvent[oCell] = "In Progress";
}
else
{
gridEvent[oCell] = "Ended";
}
}
}
It throws an error that no set method is provided for the cell object. Am I missing something?
Thanks,
Ryan

Sorry, I just realized that the datagrid's first element is 1 not zero, where in lies my problem.
Thanks,
Ryan

OK, not zero, but i figured it out.
Thanks anyways,

We are developing a C# application using .Net AsyncCallback delegates. The application currently executes, as expected,
using these asynchronous methods. Once this application is converted to a COM+ component (i.e. a .NET serviced component)
the program ceases to execute properly and 'hangs' without asynchronously executing the callback delegates.Any help with .Net asynchronous programming under COM+ would be grealty appreciated. Thanks. Rick

I am handling the double click event on a form (not a control) and I want to know the location of the double click. How? It was easy for a mouse up/down/hover/etc, it was part of the MouseEventArgs. That info is unavailable for the DoubleClick Event. Why? aaaaarrrrrggggg!

Try using the static System.Windows.Forms.Form.MousePosition.

Thanks, I had already tried that and didn't get the results I was looking for...then it dawned on me to call PointToClient before I used it. Works fine, now.

can anyone tell me what kind of help C# or .NET Framework provides to find all/any I/O device(s) installed in the system?
|
|
|
|

None. .NET (btw, C# is a language that only targets .NET - nothing special in and of itself) is a higher-level platform. C# and a few other languages that target the CLR do let you use lower-level programming with pointers in an unsafe context, but P/Invoking (calling Win32 native functions) what you need to accomplish what you want, and creating all the structs and what not, would be very time-consuming. Using C# (or the .NET Framework in general) would not be the way to go.
If you need this information in a .NET application, consider putting such functionality in a Win32 DLL and P/Invoking it, or - perhaps better - create a COM object that does this and get that information in a much simplier COM interop call.

Is there any way to make a single control usable on both Windows Forms and Web Forms?
|
|
|
|
|
Interesting question... doesn't a forms control have to inherit from System.Windows.Forms.Control and a web control System.Web.UI.Control in order to function correctly in their repsective environments?
Are you looking to make any control in particular?
|
|
|
|
|
yup actually i was thinking why repeat the code for them separately but looks like it is not possible to do so on the lines of Activex controls , they were usable in both kinds of apllications. Intersting thing is that , since Windows forms control is derived from Component class and Any Component derived from Component class can be used in a web page. IF that is right then why can't we use a Windows Forms control in a Web Page?
