'Next' Button To Navigate Records?
May 30, 2009
I have been working on database programming alot over the last few weeks, and up tell the last few days I feel like no progress has been made. I didnt understand how to use the databinding features included in Visual Studio 2008 and had a hard time hard coding. It has been making much more sense but the only book I have found thus far to be extremely helpful is a VB 2005 book. I have the database connected and displaying the records, but cant get the next and previous button working correctly (I got rid of the navigator that automatically gets added when you add a new data source, and am trying to code my own buttons). The book instructed me to create a currencyManager, and I declared it CurrManager in my code.
CurrManager = Me.BindingContext(DsCompactDiscs, "tblCompactDiscs")
this is what I coded for the CurrManager and the following is the code for the next button.....
If CurrManager.Position < (CurrManager.Count - 1) Then
CurrManager.Position += 1
Else
MessageBox.Show("No more records.")
End If
I can click next all over and over again, and once it reaches the end it gives me the message i wanted it too, it just doesnt update the textbox with the next records data.

I have a form that is used to navigate through records in a table one at a time. The form generates the number of textboxes required automatically. Navigating through the records is easy enough, but when I click the update button it comes up with the error: Object reference not set to an instance of an object.
Here is the code I have for when the Update button is clicked:
Dim con As New MySqlConnection
Dim da As New MySqlDataAdapter
Dim Query As New MySqlCommand

I have the following code i got from another thread and modified it to be able to navigate through records. The first record of the table is loaded into the textbox, but will not navigate. Tested already with a combox and worked, so i'm sure there is data in the bindingsource.
Me.BindingSource1.DataSource = MyData
Me.BindingSource1.DataMember = "ParentTable"
Me.BindingNavigator1.BindingSource = Me.BindingSource1

I made a quick Web browser that I only want to show one page when you press a button ( you have to enter a name into a textbox and it will then make the URL to show), but the page has some links on it, which I don't want people to click on.
1) Disable the hyperlinks
2) Disable left clicks in the browser
3) Make the browser somehow only visible and not actually interactive with a mouse
I tried something like
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
WebBrowser1.AllowNavigation = True
[code]....
Which I assumed would allow navigation once you clicked the button, but would then not allow it once you are done clicking it, but it just stays at false.

I have a form with two web browsers. I have webbrowser1 navigate to a parent url and webrowser2 navigate to child url.
The page in webbrowser2 loads correctly but when I make a change to an element it doesn't also change the value in webbrowser1 as it should.
Should I be looking at cookies or something else?

I want to make something that can on button click navigate to a page, wait the time I specified and navigate to another page..
[CODE...]
This does not do what I thought it would do..I think that the problem is that when it sees System.Threading.Thread.Sleep(5000) everything stops for 5 secs .How can I make it go to google.com and then after 5 seconds, yahoo?

I am rather new to vb.net using SQL CE. This is using 3.5 framework. I am trying to use a button to insert records into a table in a SQL CE database. Rowsaffected returns a value of 1, but when I preview the data, the row is never inserted. The sql statement I am using uses hardcoded values only because I am trying to get this to initially work. Once I can get the insert statement to work, it will use variables based on user input.
Here is my code that I am using:
Private Sub cmdInsert_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles cmdInsert.Click
Dim connstr As String
Dim rowsaffected As Integer
connstr = ("Data Source =" _
+ (System.IO.Path.GetDirectoryName(System.Reflection .Assembly.GetExecutingAssembly.GetName.CodeBase) _
+ ("jhepfner.sdf;")))
[Code] .....
The original database that I am using is c:jhepfner.sdf. When I run this, connstr shows:
Data Source =Program Filesjhepfnerjhepfner.sdf;
In server explorer, it shows the connection string as:
Data Source=C:Documents and SettingsCompaq_OwnerLocal SettingsApplication DataTemporary Projectsjhepfnerjhepfner.sdf

I would like for my program to navigate via textbox1.text with multiple lines and multiple url links inside of it. I know how to make the webbrowser1.navigate via textbox1.text with multiple lines, however I want my webbrowser to navigate to each url every 1-1.5 seconds once button1 is clicked. Yes, my webbrowser1 will navigate to the specified urls via the textbox1.text (multilines) with a button click, but I need the webbrowser1 to navigate in a order sequence from top to bottom of Textbox1.text (multiplelines) every 1 second. Here is the current code that I have to navigate via multilined textbox1.text control in order sequence:

I have used this form to add new records on my database(ms access) in my database I have a column name 'ID' which is my primary key 'ID' is set as auto number. Now I am having a trouble on creating my update and delete button it's always saying "cannot be delete/update"
Here's my code on add, update and delete
Public Sub SaveRecord()
Try
Dim dbConn As OleDbConnection
Dim dbInsert As New OleDbCommand
Dim str1, str2, str3, str4, str5, str6, str7, str8, str9 As String
[Code] .....
Note my add is working perfectly fine. I just can find the error on my delete and update. Also I have used this to view it to my datagrid I don't know if its the right thing but it's working fine too.
'declared dbpath globally'
Dim dbPath As String = "Provider=Microsoft.Jet.Oledb.4.0; Data Source=../VG.mdb;Persist Security Info=False"
[Code] .....
Another thing is how to code each textbox and combobox to bind it to my records so that when I click on the datagridview each column will be distributed on each respective textbox.

For my job I have to manually tick up to 50 boxes on a website and then click expire to remove the records from the site. Is it possible to automate this by having a small application which on the right hand side has a browser control and on the left a button which says expire all records. When this is clicked the tool knows to tick all the records and then click on the expire button? If so what sort of control should i look at using or VB code?
I want to progress this at a later date aswell so that the tool would then be able to click on each record individually to enter the record and then click re-publish? How do I get my program to loop round and then stop when it has finished expiring all the records? Also sometimes there are more than 1 page of results, so it would need to be able to tick all results, then click on the expire button, but then be able to click on the next page button and then repeat the process so it expires the records on this page?

I need to disable a button after its pressed so the user does not have the ability to click it again as this would replicate the process in some cases.After alot of searching I found some tips - alot of code I found I could not understand.This is what I have come up with:
On page load:
If Me.Page.IsPostBack Then
'lblDetails.Text = "disabled"
[code]....
I also read somewhere that I should use: System.Threading.Thread.Sleep(1000) to delay the process or something - not entirely sure why I would do this though.Although, the problem with my above code is that when the code behind page performs validation checks, it exits sub before executing my INSERT SQL code - so when it does this it also disables the button.I am not entirely sure if the above method is fool proof or whether it is a **** piece of code that won't work 100% of the time.On another website I found a script to put on the actual HTML page with <script> tags:
Code:
<script type="text/javascript">
disableSubmit(frm) {
