Question

using (SqlConnection myDatabaseConnection = new SqlConnection(myConnectionString.ConnectionString))
{
    myDatabaseConnection.Open();
    using (SqlCommand SqlCommand = new SqlCommand("Select Photo from Employee where EmpID LIKE '%' + @EmpID + '%' ", myDatabaseConnection))
    {
        SqlCommand.Parameters.AddWithValue("@EmpID", textBox1.Text);
        var DS = new DataSet();
        var adapter = new SqlDataAdapter(SqlCommand);
        adapter.Fill(DS, "Images");

        var imagesTable = DS.Tables["Images"];
        var imagesRows = imagesTable.Rows;
        var count = imagesRows.Count;

        if (count <= 0) return;

        var imageColumnValue =
            imagesRows[count - 1]["Image"];
        if (imageColumnValue == DBNull.Value)
            return;

        var data = (Byte[])imageColumnValue;
        using (var stream = new MemoryStream(data))
        {
            pictureBox1.Image = Image.FromStream(stream);
        }

    }
}

If the image is too large for the picturebox to fit. What is the code to make the image fit in the picturebox?

My picturebox is squared, if the image is rectangular how to it crop and show it in the picturebox like this, the lower part of the picture will be removed.

First off, in order to have any image "resize" to fit a picturebox, you can set the PictureBox.SizeMode = PictureBoxSizeMode.StretchImage

If you want to do clipping of the image beforehand (i.e. cut off sides or top and bottom), then you need to clearly define what behavior you want (start at top, fill the height of the pciturebox and crop the rest, or start at the bottom, fill the height of the picturebox to the top, etc), and it should be fairly simple to use the Height / Width properties of both the picturebox and the image to clip the image and get the effect you are looking for.
