Use MouseDoubleClick event. This way:
private void listView1_MouseDoubleClick(object sender, MouseEventArgs e) {
var item = listView1.GetItemAt(e.X, e.Y);
}

H! All
I have a problem regarding window service. When I tried to start the service from the Services, it gives me an error, "Error 1053: The service did not respond to the start or control request in a timely fashion"..
The code uses System.Threading not System.Timer..i tried to put an additional code to produce a log file so that i can see what is happening while starting in the services.., it executed the routine..from OnStart it calls a function and inside the function..it loops continuously..then i think it was five loops when the error showed up..it didnt pass to the OnStop method..
Another thing I am confused is that i can run or double click the EXE in the debug folder manually and it is running successfully. It seems that I am running an ordinary EXE not a windows service EXE..
BTW, this was built in C#.NET..
Anyone who knows this problem..Please help this is urgent..
Thanks in advance..Regards

Don't do operations that take long time on your start method. This error comes usually when the service can't start running in 30 seconds. Do all your long running tasks on a separate thread. What is your service doing on startup? Is it reading some files?

Thanks for your reply Navaneeth 
Yes, the OnStart calls a function..here's the sample code..
public void Start()
{
int intervalEnqueue;
try
{
intervalEnqueue = 600;
timer1 = new Timer(new TimerCallback(LLPlusProcess), null, intervalEnqueue, intervalEnqueue);
}
.....and here are some content of the function.....
public void LLPlusProcess(object state)
GetSMSResult getIncomingSMSResult = new GetSMSResult();
getIncomingSMSResult = null;
service = new Service();
service.Credentials = System.Net.CredentialCache.DefaultCredentials;
// get Incoming SMS with Waiting status
getIncomingSMSResult = service.GetSMS(System.Configuration.ConfigurationManager.AppSettings["clientAppKey"], System.Configuration.ConfigurationManager.AppSettings["enqueueStatus"], "Waiting", Convert.ToInt32(System.Configuration.ConfigurationManager.AppSettings["enqueueRecord"])); <---- calls a web service function here
string getIncomingSMSResultResponse = getIncomingSMSResult.ResponseMessage;
System.Diagnostics.Debug.Write(getIncomingSMSResultResponse + "\r\n");
GetSMSResultMessage[] getIncomingSMSResultMessage = null;
getIncomingSMSResultMessage = getIncomingSMSResult.Message;
....etc...
If getIncomingSMSResultMessage is NULL then it will go here..else it will save the data in the database..
catch (Exception ex)
{
System.Diagnostics.Debug.Write("ENQUEUE [EX] : " + ex.ToString());
}
System.Threading.Thread.Sleep(100);
enqued = false;
}
else
{
System.Diagnostics.Debug.Write("\r\n ---- ENQUEUE PROCESS ON GOING ----\r\n ");
}
It will loop for how many times (as per my log files) but still it will end to error i mentioned..
But if i double click the exe file from debug folder..it run successfully..is it normal for a web service exe to be manually run? Some says it shouldnt be running that way..because exe file will look for the services for it to run...
Please help..Regards!

Not usually, but you can write one that does.
What type of Timer are you using? I use a System.Timers.Timer for my Services.

H! PIEBALDconsult!
The program uses System.Threading...You may refer to my previous messages regarding my problem..
I'm confused to where is really the problem occurs..is it in the code or the way i built the service installer?
Thanks!

I debugged the program and the entire 'timer1_tick' event is SKIPPED. Here's the link to download the program. If anyone can fix my program, upload the edited program on sendspace and provide the link.
http://www.sendspace.com/file/j0tkw3[^]
I am pretty sure the mistake is in the timer1_click event or in the property of the timer1.
Also on a side note, I am new to the code project and I want to know if uploading a project file here is possible. If so, please tell me how.

No, you can't upload a project, and we probably won't download it. How about you give us the code that creates the timer ? You're saying you set a breakpoint in the timer and it never fires ?

Open Form1 in the editor. Select the timer1 component - it's in the gray area below the form. Right-click on it and select "Properties". There's a list of properties on the right. Above that list is a small icon with an icon that resembles lightning. Click on it, and you'll get a list of events. Click on the Tick event and set it to timer1_Tick. That should hook up the handler.
Alternatively, you could do this from code. Double-click on your form in the editor to create an OnLoad event, and add this code;
private void Form1_Load(object sender, EventArgs e)
{
timer1.Tick += this.timer1_Tick;
}Welcome to CodeProject

Wow - you can set timers in the designer ? I've never tried that ( nor am I likely to, but.... )

yes, a lot of non-GUI stuff can be designed: timers, BackgroundWorkers, SerialPorts, ...

Thanks, I didnt put it in the form_load event, instead put it in the start event and now my program works. LOL I can't believe I didn't realize that my tick event was never executed. THANK YOU VERY MUCH!
Edit:
I had to add a timer1.Tick -= this.timer1_Tick; on pause & restart though and I had to disable pressing restart on pause. Oh well, at least the program works. Thx

Hi,
do you have a timer1.Start(); statement somewhere, and are you sure it gets executed?

I'm sure that there have been a thousand questions on this topic, but here goes...
I have an application that uses the System.Net.NetworkInformation.NetworkInterface.GetAllNetworkInterfaces() to retreive each friendly interface name on a machine with multiple adapters. Later, depending on other choices, the application needs to start UDP multicasting. For this I need to be able to find the IP address of the interface chosen. As I said, all I have is the friendly adpter name. How can retreive the IP address(es) of the NIC starting only the adapter name?

Are they if you set Windows to not cache it? Also there aren't going to be these files created on read-only media, so I guess there muse be some API for that...

Do you know how can I get the corresponding project of a custom component at design time?
For example: a custom list box resides in a form which belongs to a project. I need to access that project, from inside of the listbox, at design time.
Thank you.
Bogdan.

What do you mean, 'access the project' ? The csproj file is not there, nor can you change it's settings in the compiled dll. If you want the name of the project, if it happens to be the name of the main namespace, as is the default, you can get the name via reflection, but, given that it never changes, I assume this is not what you mean ( plus, I can't think of any reason to want to do this )

Is there anyone that can point me in the right direction were to start if I want to be able to manipulate the content on the page?
I know HTML and some DOM, now it's just how i can access the code behind to collect data and to change it on the page.
Thanks in advanced.

Okay, I think that I understand the issues affecting C# equality testing (including numerical precision, type conversions, boxing etc) - e.g. http://blogs.msdn.com/jmstall/archive/2005/03/09/390135.aspx[^] - but I don't understand the statement in MSDN (http://msdn.microsoft.com/en-gb/library/bsc2ak47.aspx[^]):
x.Equals(x) returns true, except in cases that involve floating-point types. See IEC 60559:1989, Binary Floating-point Arithmetic for Microprocessor Systems.
Can anyone please explain? How can this sometimes evaluate to false?
(I couldn't find anything interesting re: IEC 60559:1989 - still Googling though.)
P.S.
double d = Double.NaN;
d.Equals(d);

Hi,
the MSDN documentation on Object.Equals says:
This method can be overridden by a derived class.... The following statements must be true for all implementations of the Equals method...
x.Equals(x) returns true, except in cases that involve floating-point types. See IEC 60559:1989, Binary Floating-point Arithmetic for Microprocessor Systems.
so all it says is xfloat.Equals(xfloat) is ALLOWED to return false; it just leaves the Equals() result for floats undefined.
The IEC standard isn't available for free, so I can't check this, however I assume they call the result of x==x undefined, hence hardware that implements IEC 60559:1989, and software running on such hardware, would find it difficult to enforce x.Equals(x) returns true.
The fundamental reason is it does not make sense at all to test two floats for equality; by their very nature, float values are either close to each other (difference less than epsilon), or they are not. Zero does not exist in nature.
