i think i 've found a solution to find the row and the cell
Point pointeur= miniature.PointToClient(new Point(e.X, e.Y));
for (int i = 0; i < imgList.Length; i = i + 170)
if (pointeur.X > i && pointeur.X < i)
{
//in the cell
if (pointeur.Y > 0 && pointeur.Y < 170)
{
//in the cell and the row
}
}

From what I see you are trying to do, and a quick glance, looks like you are on to something
Good luck and happy coding

Hello everyone,
I was wondering if there is anyway that I can change the colour of the Text displayed in a TextBox programmatically ?
Thank you very much and have a great weekend.

Use the Foreground for changing the text color, Background for the background color.

I’m POSTING to an ashx file from my aplication.
What I want to do is just post information about some variables of my aplication, and never wait for an answer.
What I need is to avoid waiting for an answer, because I don’t need it.
I’m accesing the file this way.
-----------------------------
string queryString = "http://website/PrivateHandler.ashx";
System.Net.HttpWebRequest myHttpWebRequest = (System.Net.HttpWebRequest)WebRequest.Create(queryString);
myHttpWebRequest.Method = "POST";
myHttpWebRequest.ContentType = "application/x-www-form-urlencoded";
string strRequest = "mode=1&bID=1&gID=1";
UTF8Encoding objUTF8Encoding = new UTF8Encoding();
byte[] arrRequest = objUTF8Encoding.GetBytes(strRequest);
myHttpWebRequest.ContentLength = arrRequest.Length;
Stream strmRequest = myHttpWebRequest.GetRequestStream();
strmRequest.Write(arrRequest, 0, arrRequest.Length);
strmRequest.Close();
//Wait for an answer (I don’t need an answer).
System.Net.WebResponse resp = myHttpWebRequest.GetResponse();
System.IO.StreamReader sr = new System.IO.StreamReader(resp.GetResponseStream());
sr.ReadToEnd();
---------------------------------
WebResponse and ReadToEnd are there because if I don’t read what return, I can only call the ashx file twice and then the system hangs.
What I need is to post multiple times and never wait for an answer and waste performance because of that.
Is there a way to achieve what I need?
Thank you very much.

It appears your are trying to use an HTTPHandler as a Web Service. Why not just create a Web Service?

Thanks for your answer.
If I use a WebService, won´t I have a lot of extra overhead?
I´m trying to avoid overhead as much as possible.
Thanks again.

You will have a better performing solution. A HTTPHandler isn't meant to be used in the manner you are trying.

I am writing a C# application that detects USB drives as they are plugged in.
I want to do different automated operations on the drive depending on which USB drive I plug in (ie if it is a new drive or one that has been previously plugged in).
The easiest way to achieve this would be to read the hareware ID off the USB drive. Unfortuneately I do not no how to do this in C#.
Does anyone have any ideas on how I could achieve this or if there is a C# class that returns this type of info?

Hi,
I have a windows service installed in my machine and User can create multipe instance of the Same service dynamically. Now the Problem is how to get the Name of all the Instance of the Windows Service from my windows Application using WMI ?
people laugh at me because they say im different and I laugh at them because they are all the same.
|
|

|

Are you sure it is a windows service? You can only install unique named windows services so I am a little confused by your statement about User can create multiple instances of the same service. The service is always running and perhaps the service launches a windows app then or something?

Of Course it is a windows service...The name of the Service is Of Course Unique...but has one Executable.

Hello everyone,
I have a DataGridView which is populated by data from a remote DataBase server. The following code show this:
OdbcAd = new System.Data.Odbc.OdbcDataAdapter("SELECT * FROM company;", OdbcCon);<br />
<br />
OdbcAd.Fill(myds4, "company");<br />
<br />
dataGridView4.DataSource = myds4.Tables["company"];
I was wondering if it is possible to access the data in the DataSet rather than in DataGridView?
For example:
I am using the following line of code to get the "company_name" value and display it in an TextBox.
txtCompanyName.Text = dataGridView4.Rows[FilterCompany_id].Cells["company_name"].Value.ToString();
My question is, rather than tapping into DataGridView4; can I tap into "myds4" which is the DataSet holding the entire unfiltered data since I am applying filters to the data shown in the DataGridView?
Thank you very much and have a great day.
