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 ?

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.

<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!

You can define columns for a temporary DataTable?

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:

<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:

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();

Good day all,

I am a beginner in programing and I can't get the below code to function properly.

when I use the two Response.write(role)statements, the code executes fine but when I comment them and use Response.write("users page") and Response.write("admins Page"), I always get the response: "admins page".

can someone please help and explain why this is happening?

myCon.Open();

                        SqlCommand com3 = new SqlCommand("checkRole", myCon);
                        com3.CommandType = CommandType.StoredProcedure;
                        com3.Parameters.AddWithValue("@uName", TBoxUName.Text);
                        String role = com3.ExecuteScalar().ToString();

                        myCon.Close();



                        if (role == "user")
                        {

                            Response.Write("Users Page");

                            //Response.Write(role);

                        }

                        else
                        {

                            //Response.Write(role);
                            Response.Write("Admins Page");

                        }

When you use Response.Write(role), what value is written to the response?

The equality operator for strings is case-sensitive. If the role contains "User", it won't be considered equal to "user". You'd need to use the string.Equals method passing an appropriate StringComparison option instead:

if (string.Equals(role, "user", StringComparison.OrdinalIgnoreCase))
{
    Response.Write("Users Page");
}
else
{
    Response.WRite("Admins Page");
}

The value I get when I use response.write(role) is lower case e.g. user or admin which is exactly the same as the string literals I am using in the if statements

Check the output of your stored procedure. It may not be returning what you think.

All you need to do is put a breakpoint and step through the code. You'll be able to see exactly what is happening. As pointed out, it's likely a case sensitive issue.

1. Smells like homework. We will not do your (home)work for you.
2. Read the guidelines about posting a question. The subject "plz" is not really helpful
3. Open up google and read up about generic methods. Take your class notes as well. Then try to come up with a solution. If you get stuck, post the code you tried here and ask a specific question.
