Will not work for "every" site, as the hosts file doesn't accept wildcards.

Install a proxy, and use only that proxy to connect to the outside world.

It's either that or writing your own firewall; A proxy will only be usefull if you own the network, and a virusscanner only if you own the clients. And yes, it might break a lot of websites using SSL, as should be.

I should to solve next task:

RECOGNITION OF EMOTIONAL EXPRESSIONS ON HUMAN FACES
IN DIGITAL IMAGES
1. Results
1.1 Limitations of implementation
1.2. Training (learning) set (in the case of the learning based method)
1.3. Testing set and corresponding visual results of recognition
1.4. Analysis (correctness of recognition, problems, speed – is it fast enough for real time interactive foreign language learning)

How could I solve this task?
Is backpropagation learning algorithm good approach for this?
How to start preprocessing and so on.

Google for "image recognition", there are many resources around to guide you.

You won't get that "answer" in a forum, as there is no answer. It's a complete topic.

There's a lot more out there[^].

No, it's not.

I am doing a project on retrieving similar face images from a folder by giving a query face image and but the results are not satisfactory. I taught if I crop the images to its face and then search the results might be better. but I am having trouble in cropping multiple images since a folder might contain multiple images. I need help on that.....?

There are several solutions for that. It calls: picture resizer[^]

Going through a folder/directory and selecting multiple files ... in that directory only ... that meet certain criteria is easy to do: [^].

If the folder you wish to search for files contains sub-directories (other folders), then, beginning with .NET 4.0, you can use the Directory.EnumerateFiles method with SearchOption.AllDirectories to recursively search: [^]. If you do not have permission to open any sub-directory, the search will fail.

I am curious: how you are doing cropping now: what algorithm are you using; or, what image editor do you use; or what web-something-or-other are you invoking ?

I first detect the face in an image and then represent it with a rectangle. Then separate the rectangle and remove parts of image other than what is inside the rectangle.

I think knowing how you "select the face" is a key piece of information here: are you doing by using your eyes ... or, is it automated in some way ?

Please tell me how to write this code & how to run it.

What should be the application types,
I 've a quick solutions to make 3 web applications works with HTTP REQUESTs
Please let me know if those are applications are of type "Web", so that I can share my things with you.

Thanks

This question is far too vague and generalised to get a good answer. You need to start by defining the data that will be held in the first app and how it will be made available to the second one. And, in turn, how that data will be made available to the third one for display. In reality it sounds like an academic exercise, but we need much more detail.

Google for the word "Database".

<pre>Hello,

I introduce myself, I am instrumentalist electronic I have a project to make a programming change mark 6 mark to one that is the center of gravity as shown in the picture

pins (Z1, X1, Y1) (Z2, X2, Y2) (Z3, X3, Y3) (Z4, X4, Y4) (Z5, X5, Y5) (Z6, X6, Y6) to the approximate center gravity (Z7, X7, Y7).

I admit you know absolutely anything about programming in C #, the data that I have is that gives me pins angles (theta, zeta, iota) that from what I could make the change of reference (translation and rotation) to come to the reference (Z7, X7, Y7).

If you can guide me or given lessons in PDF format or other tutorial where I could take care of myself I'd like at least I suggested I took a lot of late, thank you in advance</pre><pre lang="c#"><pre lang="c#"><pre lang="c#"></pre></pre></pre>

Sorry?
I'm afraid that that means nothing to me whatsoever.

The picture you reference isn't there - possibly because you can't post images in unmoderated forums on this site - but even with it I'm not sure that I'd understand what you are talking about.

If you need an image (and you probably don't) post it up on DropBox and the post a link to the image.
Then sit back and forget everything you know about your problem. Then read your question. Do you have any idea what you are talking about? Because we can't see your screen, access your HDD, or read your mind - we only get exactly what you tell us.
So edit your question, and try explaining your problem in better detail!

I would like to find a source code that can make a change of reference in real time 3D modlisation human.

can we draw lines in richtextbox?

yes it is possible to draw line in RichTextBox.

see this:

Friends, good morning everyone.
I am needing to define the columns and their characteristics to a temporary DataTable, and not let it generates the columns, the data are inserting correctly, I have my grid:

C#

<asp:GridView ID="GridResumoTotal" runat="server" Height="2px"
Width="100%" AutoGenerateColumns="true" >
</asp:GridView>

I wanted to set my grid with the fields and formatting without using AutoGenerateColumns
I greatly appreciate the help!

I'm doing this:

C#

protected void Page_Load(object sender, EventArgs e)
{

if (!IsPostBack)
{
//dataTable para guarda dados temporario
dtb = CriaDataTable();
Session["mDatatable"] = dtb;
GridResumoTotal.DataSource = ((DataTable)Session["mDatatable"]).DefaultView;
GridResumoTotal.DataBind();
}

//criar um DataTable temporário
private DataTable CriaDataTable()
{
DataTable mDataTable = new DataTable();
DataColumn mDataColumn;

mDataColumn = new DataColumn();
mDataColumn.DataType = Type.GetType("System.String");
mDataColumn.ColumnName = "MODALIDADE";
mDataTable.Columns.Add(mDataColumn);

mDataColumn = new DataColumn();
mDataColumn.DataType = Type.GetType("System.String");
mDataColumn.ColumnName = "QTD_OBJ_16";
mDataTable.Columns.Add(mDataColumn);

mDataColumn = new DataColumn();
mDataColumn.DataType = Type.GetType("System.String");
mDataColumn.ColumnName = "QTD_OBJ_17";
mDataTable.Columns.Add(mDataColumn);

return mDataTable;
}

private void incluirNoDataTable(string modalidade, string qtd_obj16, string qtd_obj_17, DataTable mTable)
{
DataRow linha;
linha = mTable.NewRow();
//gera o número GUID
//linha["CODIGO"] = Guid.NewGuid().ToString();
linha["MODALIDADE"] = modalidade;
linha["QTD_OBJ_16"] = qtd_obj16;
linha["QTD_OBJ_17"] = qtd_obj_17;
mTable.Rows.Add(linha);
}


GridResumoTotal.Columns.Clear();
incluirNoDataTable("TOTAL GERAL DIA : ", footer.Cells[16].Text,footer.Cells[17].Text, (DataTable)Session["mDatatable"]);
GridResumoTotal.DataSource = ((DataTable)Session["mDatatable"]).DefaultView;
GridResumoTotal.DataBind();
