Adding Data To A Table On Button Click?
Jun 2, 2011
Im looking to add some information to a table in VB.net.The table needs 2 columns and a number of rows;1 Column needs to have numbers ranging from 1 onwards, basically representing their row number. And 1 more column which just displays any text when a button is pressed.
Each time the button is presed i need the text to go onto a new row.Ive heard alot about a DataGrid, but everything relating to this seems to be based with SQL and I was wondering if there is a differnet tool which would be simpler to use?

In the example from my book, I'm coding a button click event, and adding the code..."me.width=me.width + 20"The author states that "me refers to the object to which the code belongs(in this case the form)".
But this isn't exactly accurate, is it? The "code belongs" to the button object -- not the form object, right? So, I'm guessing that what the author really should have said is that "me refers to what ever form you're working on". Would that be true?

I have already binded a data source from Access to my visual basic program but need to add a True/False column to two of the tables. I could do this manually in access and re-bind the sources but that would take up too much of my time so I wanted to know if I'm using the proper code to add a column to the data table directly from VB? Here is the code I want to try but I don't know where to place it?
OleDbCommand = OleDbCommand("ALTER TABLE tableName ADD
FieldName DataType");
(something).Connection = OleDbConnection;
[Code]....
I'm not sure what goes into the "something" parenthesis and where this code must go. I already tried editting through the data designer but although it shows the column in the DataGridView, it does not save any data or the column into the actual access file.

I am trying to add a new record to a Visual FoxPro data table using an ADO dataset with no luck. The code runs fine with no exceptions but when I check the dbf after the fact there is no new record. The mDataPath variable shown in the code snippet is the path to the .dbc file for the entire database. A note about the For loop at the bottom; I am adding the body of incoming emails to this MEMO field so thought I needed to break the addition of this string into 256 character Chunks.
cnn1.Open("Driver={Microsoft Visual FoxPro Driver};" & _
"SourceType=DBC;" & _
"SourceDB=" & mDataPath & ";Exclusive=No")

I am working on an aspx site that lets an admin-level user fill out a form with potential member data. Once the form is filled out, the user will click submit and the data will go off to different tables. One part of the form that is stumping me involves filling out three textboxes (txtFirstName, txtLastName, txtGrade). I have a button (btnAddStudent), that, when clicked, should add the information from the textboxes to a table-like display area. I am trying to use a gridview, but there is nothing to bind it to. There is no memberID number to load a blank record from the Student table (which is a many-to-one relation to Member table). The member record is what this form is creating, and the student data will be added to the Student table when the Submit button is clicked.
I am currently working with the code found in the reply here. But when I click the "Add Student" button, I get a new blank row, but my textbox values are not inputted in the gridview.
Can this work, or do I need to look at using a table and adding rows of textboxes dynamically?
Here is relevant source code:
<tr>
<td class="style8">
<asp:Label ID="Label18" runat="server" Text="Chidren:" Font-Bold="True" Font- Underline="True" Font-Names="Tahoma"></asp:Label>

I have managed to automate the following page: https://post.craigslist.org/atl/S/msg/none/x and even click the "Continue" button, but I noticed that my vb 2008 program is creating an infinite loop and tries to click "Continue" buttons on following pages. I only want my program to click the continue button once, fill out more data on the next page and then click another continue button on a later page. But I need the following code to end on the first page before I can continue coding for the following pages so that the web browser doesn't go crazy.Here is the code that I am using and not sure if this is called an infinite loop, but that is what it seems to be doing:
theElementCollection = WebBrowser1.Document.GetElementsByTagName("button")
For Each curElement As HtmlElement In theElementCollection
If curElement.GetAttribute("value").Equals("Continue") Then[code].......
