[b]hey to all the forum
i create a tablelayoutpanel populated with label and pictureBox automaticlly loaded from a folder
and xml file
and i wanna know when the user select (click) on one of the picture or the label
and what's the coordinate of the selected cell
this is the code my tablelayoutpanel is named miniature[/b]

<code>imgSize = new Size(170, 170);
scanDirectory(folder, "*.jpg", System.IO.SearchOption.TopDirectoryOnly);
String selectedImage = selectedImg;
if (imgList == null)
return;
int a = 0;
miniature.ColumnCount = imgList.Length;

foreach (String img in imgList)
{
com_image.Text = com_image.Text + img + "\r\n";
l = new Label();
l.Text = img;
l.TextAlign = ContentAlignment.TopCenter;
miniature.Controls.Add(l, a, 2);
PictureBox pb = new PictureBox();
pb.Size = imgSize;
pb.SizeMode = PictureBoxSizeMode.Zoom;
pb.Image = Image.FromFile(img);
pb.BackColor = Color.White;
pb.Tag = img;
miniature.Controls.Add(pb, a, 0);
a++;
}


</code>

i tried miniature.GetCellPosition(); and miniature.PointToClient(new Point(e.X, e.Y));
but i don't know how to convert point to controls

thanks in advance

Off the top of my head, can you get the index of the selected cell's row? That might be better.

In minature is there anything such as Clicked or any event procedure that gets fired when you click on the controls? If so, you should be able to get info on the object that was clicked.

there's a "private void miniature_MouseClick(object sender, MouseEventArgs e)"
but they treat all the tablelayout not cell by cell
you see?

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
}
}

Build a timer control,then change the form's transparence--Just change the form's Opacity Property.

How can I avoid waiting for a response after an HttpWebRequest POST?

kontrolakka1-Jun-07 9:40

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.
