Hi, i'm not a rookie but i'm not (at all) an expert in VB, a few months ago, i created a simple program to auto renew my books from my school's library. The code works well, i just use a webbrowser navigate to it, and the click the buttons with a timer (that consider the internet speed, changing the time to start). e.g.: WebBrowser1.Document.GetElementById("login").SetAttribute("value", TextBox1.Text) / or WebBrowser1.Document.GetElementById("btn_gravar").InvokeMember("click") ... simple as that.

but now i want (after the renew thing) to withdraw some information on the page, i searched a lot of tutorials (some with, almost, the same problem as me) but none of them worked, it looks so simple but i cant find a way to work with. can you help me?

here is the website code (since you can't log in to see)

what i want is:
(1) Return until: 14/09/2017
(2) Total of renewals performed: 0
(3) Reference: MONTEIRO, Washington de Barros.

Code:
<div id="1b" style="">
        <table width="100%" border="0" cellspacing="0" cellpadding="0">
			<tbody><tr>
				<td class="box_do_detalhes">
					<table width="100%" border="0" cellpadding="0" cellspacing="0">
						<tbody><tr>
							<td colspan="2" class="box_f7f7f7_c">Reference: MONTEIRO, Washington de Barros. <b> Curso de direito civil. </b> <b></b> 36. ed. São Paulo: Saraiva, 2001. 350 p.  ISBN 8502020439 </td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c"><em><strong>Call number: 342.1 M775c 2001 (BU-JC)</strong></em></td>
							<td class="box_fffff_c">Unidade de Informação source: Biblioteca </td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c">Type of loan: Estágio             </td>
							<td class="box_fffff_c">Description: v.2                                                 , nº 4 </td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c">Date of loan: 31/08/2017 07:52:55</td>
							<td class="box_fffff_c">Return until: <strong>14/09/2017</strong></td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c">Fine partial amount: $ 0</td>
							<td class="box_fffff_c">Total of renewals performed: 0</td>
						</tr>
					</tbody></table>
				</td>
			</tr>
        </tbody></table>
	</div>
here's a second example, (a second book) this goes on, 1b ; 2b; 3b; 4b; 5b; 6b; and 7b (since 7 books is the max you may retain)
Code:
<div id="2b" style="">
        <table width="100%" border="0" cellspacing="0" cellpadding="0">
			<tbody><tr>
				<td class="box_do_detalhes">
					<table width="100%" border="0" cellpadding="0" cellspacing="0">
						<tbody><tr>
							<td colspan="2" class="box_f7f7f7_c">Reference: FIUZA, César. <b> Direito civil:  </b> curso completo. <b></b> 12. ed., rev., atual. e ampl. Belo Horizonte: Del Rey, 2008. xxiv, 1084 p.  ISBN 9788573089868. </td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c"><em><strong>Call number: 342.1 F565d 2008 (BU-JC)</strong></em></td>
							<td class="box_fffff_c">Unidade de Informação source: Biblioteca </td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c">Type of loan: Estágio             </td>
							<td class="box_fffff_c">Description: nº 6 </td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c">Date of loan: 31/08/2017 07:53:07</td>
							<td class="box_fffff_c">Return until: <strong>14/09/2017</strong></td>
						</tr>
						<tr>
							<td class="box_f7f7f7_c">Fine partial amount: $ 0</td>
							<td class="box_fffff_c">Total of renewals performed: 0</td>
						</tr>
					</tbody></table>

        </tbody></table>
