Here is what you need:
1.A timer
2.A Label (Called label3 in the example)
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
Label3.Text = Cursor.Position.X.ToString & "," & Cursor.Position.Y.ToString
End Sub
Hope this helps

I am using a Symbol device and my application pre-requisites include installing the symbol.all.arm.cab on the device.
The first time I installed the pre-requisites and the application on the device, the application ran properly without any crash.
But later, when I tried to start the application again, there was an error seen and the application did not start.
The following error was seen
TypeLoadException
Could not load type
Symbol.Generic.Reader from assembly Symbol,
Version=1.0.5000.3, Culture=neutral, PublicKeyToken=68EC8DB391F150CA.
MSDN says “TypeLoadException is thrown when the common language runtime cannot find the assembly, the type within the assembly, or cannot load the type.”
I tried reinstalling the ‘symbol.all.arm.cab’ file again, but it gives the same error.
can anyone help me in understanding why am I getting this error and what should I do to correct it.

Please don't cross post. Pick an appropriate forum and ask the question there.

Hi
When I type netstat -a in command, it shows a specific (tcp)port is still "listening" even though the program that was using that port was shutdown. So it wasn't closed properly. I just want to know how I can close that specific port in C# .NET. Because when my program starts again, it says that port is busy.
Thanks for any help

I have been trying to use timers in VS 2005. I was under the impression when the tick event fired it was similar to a hardware interrupt . Time has shown I am incorrect, I am now using a separate thread.
My question is: what is happening when the tick event fires, is it sitting in a queue waiting for a break in the thread, is it lost if the thread is busy else where, or something else?
Thanks
Jim

That depends on which Timer is being used. There's 3 in the .NET Framework.
The System.Threading.Timer is a uses a callback delegate, which is executed on a Thread from the ThreadPool.
System.Timers.Timer is a server-based timer designed to work from worker threads in a multithreaded environment.
System.Windows.Forms.Timer is a event-based timer designed to work in a single threaded environment on the thread with your application message pump and relies on the O/S timer support.
The Timers.Timer and Forms.Timer both use events to signal the elaspe of the timer. The events are queued and must wait for the thread handling the events to get around to them.
The Threading.Timer uses a direct call to the code handling the elaspe of the timer. It doesn't have to wait for a thread to handle a queued event, but instead creates a new thread out of the ThreadPool and executes the method on that. The only thing that would slow that process down is if the ThreadPool doesn't have a thread immediately available to execute the request.

I have made small testing app. Iniatialy I have used database connection via IDE (Data Sources -> Add New Data Source), later I have shifted my project to another PC so I had to change Data source.
I have removed old data source from IDE, attached database to another server and stored connectiong string in App.config file.
BUT when I tried to reach this information first time I found out there were more than one conn string!
Old one (which was never in App.config!) and new one.
My confusion was even greater because I haven't had .config file (nor -.settings) prior the change of data source.
Where is old connection string stored? It's not in App.config!
I made ad hoc solution for the moment, method shown passes first usable connection string:
<br />
public static bool ProvjeriKonekciju()<br />
{<br />
bool povrat = false;<br />
SqlConnection conn = null;<br />
Configuration config = ConfigurationManager.OpenExeConfiguration(ConfigurationUserLevel.None);<br />
ConnectionStringsSection section = config.ConnectionStrings;<br />
ConnectionStringSettings settings;<br />
<br />
for (int i = 0; i < section.ConnectionStrings.Count; i++)<br />
{<br />
settings = section.ConnectionStrings[i];<br />
if (settings == null) continue;<br />
<br />
conn = new SqlConnection(settings.ConnectionString);<br />
try<br />
{<br />
conn.Open();<br />
if (conn.State == ConnectionState.Open)<br />
{<br />
povrat = true;<br />
_ConnString = settings.ConnectionString;<br />
povrat = true;<br />
break;<br />
}<br />
}<br />
catch (SqlException sqlex)<br />
{<br />
Debug.WriteLine(sqlex.ToString());<br />
}<br />
catch (Exception ex)<br />
{<br />
Debug.WriteLine(ex.ToString());<br />
}finally<br />
{<br />
conn.Dispose();<br />
}<br />
}<br />
return povrat;<br />
}
How can I eliminate the intruder?
I'm using Visaul C# 2005 Express.
Help.
I'm not native English speaker, so excuse me.
Feel free to point out bad code aswell.

Connection strings can also be stored at the machine.config level. So if you are seeing another connection string it can be from there.
A better way to access the connection string if you are using .net 2.0 would be to get it from the ConfigurationManager.ConnectionStrings. This should be only the value you have set in the app.config file. When you open the configuration file like you have in the above code it may be looking into the machine config as well.
Hope that helps.

No. That was my first choice, but it also has sent me two connStrings.
I thought code shown above will help me (well that was the idea I got after reading msdn).

Sir,
I got these two exceptions, 1. System.Runtime.InteropServices.GUIDAttribute - cant be specified multiple times and
2. System.CLSCompliantAttribute - cant be specified multiple times with Indentical parameters also.
Why do I get these exceptions and how can I clear these exceptions. Thank you.

I'm guessing you have a GUIDAttribute and a CLSCompliantAttribute specified more than once for a class? The clue is in the error message.

|
|
|

But I am not getting how should I clear it. Pls. give me some example how to clear that error. Thank you.

Obviously, if the error says 'don't specify this multiple times', you need to only specify it once, whereas you're currently specifying it MORE than once.

Both of these attributes are generally specified in the AssemblyInfo file. This file is included only once in the project, so the attributes are defined only once. The attributes do not exist in this file by default, so you would need to add them.
If you think these are defined more than once (which the compiler obviously does), then search using "Find in Files" for the attribute names and remove the duplicates.

Are you not perhaps specifying class targeted attributes on methods?

Hi,
Is it possible to set the load order for the windows service? So for example, I want to have my windows service loaded last after a system boot up. Is that possible? Thanks for and any replies.

I don't know of any way that you can force a service to load last, but you can set a dependency on other things. I had an issue where the Message Queue MSMQ needed to load first before my service.
In the ServiceInstaller file you add this:
this._serviceInstaller.ServicesDependedOn = new String[1] {"Message Queuing"};
So if there are other services that need to be running first. Just put there name in the above code instead of the "Message Queuing".
Hope that helps.
