You can create your own class that derives from ListView, override WndProc and catch WM_MOUSEWHEEL to raise an event and/or handle it directly there.

You can directly and eventhandler Mouse_Wheel (sth like that) to the listview you use.

Seraph_summer is correct - for some reason MS have hidden it from the designer but it's available in the editor. I'll check the source later and see if I can figure out why!
listView1.MouseWheel += new MouseEventHandler(listView1_MouseWheel);
void listView1_MouseWheel(object sender, MouseEventArgs e)
{
}

You either use the WMI with the Processor class in WMI and then you will right the methods to do so ... or use the already wrapped class for WMI managment System.Managment where the class to use is the Win32_Processor ...
Any way here is a sample example of retrieving Processor Information using System.Managment for a local machine ... read about the subject more and you will get how to get it using another machine (you map your IP to machine name then use machine name with System.Managment ... something like that  ) http://friendstertalk.com/t50165-Use-WMI-to-get-processor-information-%5BC%23%5D.html[^]

The "processor ID" is not really a unique ID. It's a series of capability flags. Therefore, if you have two servers running the same CPU, they'll both return the same ID.

Hi.
I'm building an application which has to return a value from a database, conditioning on two things.
The database looks like:
|Workplace|
------------------------
ID | Description | Morning | Afternoon | Evening
Description: Description of the workplace
Morning: The hourly wage on this workplace
Afternoon: The hourly wage on this workplace
Evening: The hourly wage on this workplace
Example of a database:
1 | Warehouse | 1,3 | 3 | 3,7
2 | IT | 2,5 | 4 | 5
3 | Maintance | 2 | 2,5 | 7
Ok, we've cleared about the database... now lets got to the program.
In the app. the user must choose When did he work and when. That means, he chooses the ID of the workplace and when did he work.
The app. must then return the value of selected workplace and the wage on the selected time he worked. Thats the problem.
A friend of mine said, that in VB 6 and ADO (not .NET), it was quite simple. You could use the select string and then something with recordset.recordcount and then if recordset field value = ...
I googled and googled and in the end i didnt know what i was googleing The result - found nothing.
Again, im turning too the CodeProject community for help...
Thanks for taking your time to read and i hope you can help

Its a simple select statement returning (I assume) 1 row with all the columns, from which you select the rate dependant on the time selected by the user. All you need to do is google for "datareader", there are literally thousands of examples. The better alternative is to google for ado.net as again, there are thousands of articles and you will gain a better understanding of datareaders, datasets etc.
BTW,

sounds like a long way round!
Hope this helps

Thanks for your answer... eventhough i didnt need datareader with this
The solution to my problem looks like this:
<br />
OleDbConnection dbConn = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + "C:\\db.mdb");<br />
<br />
string sqlComm = "SELECT * FROM Workplace WHERE ID=2";
OleDbDataAdapter da = new OleDbDataAdapter(sqlComm,dbConn);
DataSet ds = new DataSet();<br />
da.Fill(ds);
<br />
string selected = ds.Tables[0].Rows[0]["DelovnoMesto_PopTarifa"].ToString();
Thanks again
Regards,
Matjaž

Thats one way, but for performance a datareader is better than filling a dataset - particularly when you are only expecting 1 record.
Also, stored procedures or parameterised queries are preferable (for security and performace reasons - google for sql injection) and it is also bad practice to do select * as you are generally returning more data than you actually require - not significant in this case, but if it was a table with many columns and millions of rows... However, I expect you were just showing sample code and you are aware of this.
Anyway, at least you have got there

Hi EveryOne, I have to format string being entered in the TextBox Control, i.e, in the (Lat/Long)format 00 00.000, dynamically as the text is being entered into the textBox,
Please help me out with this issue...
Thanks in Advance...

I am not sure if I got your question ... while you are pressing keyboard keys on the text box .. you want to add each one in its approperiate place (e.g add 12 34.567 with the format 00 00.000) and validate the possible inputs at the same time ? I can direct you to a living example of such a case is the MaskedTextBox in Windows Forms ...
MaskedTextBox have the ability to have a predefined mask or a custom mask ... where I think will fit your needs ... take a look at it it will help you ... if you are using Web then you can build your customs control and use Regular Expressions with it as well.

Follow these steps :
1)- Splite the whole string "," and stored in Array
2)- Create an Array List
3)- Traverse the all items which is stored in step 1 and perform the below opetion
In Loop, again splile with "-" and pick the secod item every time and store in Arrya list which created in step 2
4)- Sort the array list which stored in step 3
5)- Pick the Max value (First index of arraylist)

You did not tell us your problem.
Also this suspiciously looks like web stuff and not C#, try the ASP.NET forum.
xacc.ide - now with TabsToSpaces support IronScheme - 1.0 beta 1 - out now! ((lambda (x) `((lambda (x) ,x) ',x)) '`((lambda (x) ,x) ',x))

Use the getTime method to get the date in milliseconds, add the number of milliseconds in 15 days, and create a new Date object from the result.
Note that the month value is zero based, so you have to add one to get the one based value that humans use.
Despite everything, the person most likely to be fooling you next is yourself.
