VS 2008 Code To Automatically Update Webpage?
Jun 1, 2009
I'm trying to design a small program for my home server that automatically updates an HTML page every time a new file is added to a certain directory.Example, say I already have 100 files in "C:Folder", and on the HTML page, all those files are listed in a table, and when you click on one of them, the file opens, say I add a new file to the folder, I want the program to automatically add that file to the list of other files, and put *NEW* next to it (newfile.txt *NEW*), and I would like it to say *NEW* for 5 days, so how would I go about making a program that does all that?

I have a standard DataGridView. One of the columns is a DataGridViewComboBoxColumn. When I select one of the ComboBox items, I want to trap the change and add additional columns based on the item selected in the ComboBox. I've tried using CellValueChanged for the DataGridView column, and a bunch of other events, but none of them is fired when the DataGridViewComboBox value is changed. What event can I trap to make this happen? Right now as I said, I am using CellValueChanged, but of course the event doesn't fire until I click on another cell...

Ok I was wondering how can I grab the source code from webbrowser1. The problem is that I cant find this line of code in the source code. I cant only find it if I highlight what I want and do a right click and look for the source code. I heard is was like a hidden part of the source code. How canI implement that in my program?

About some coding in visual basic.NET 2005. I was wondering if it was possible for code to be altered automatically if a certain event was triggered. For example; would it be possible for you to alter the following structure, say if a a button was pressed?
The structure is as follows:
Structure ClientDrawings
Public ClientID As String
Public Drawing_1 As String

I am navigating to a website using a webbrowers control and I wish to automatically scroll the page after it is loaded. I have used scrolltop , scrollleft commands as set out below but nothing seems to happen.
WebBrowser1.Document.Body.ScrollTop = 100
WebBrowser1.Document.Body.ScrollLeft = 200
I have placed the above commands in a command button and wait until the page has loaded before I press it and also in the
WebBrowser1_DocumentCompleted sub
Other commands such as
WebBrowser1.Document.Body.ScrollIntoView(True)
Seem to work ok.

I wanted to ask you something which is bugging me for a while. I work an IT dept at a local bank and I got instructions to make an application which should retrieve some financial info from a financial banking stats page.
The webpage can be accessed through [URL].. and the info can be seen in the web browser but I cannot extract them because the info is not available in the source code of the page.It seems it's generating the info dynamically using a jsquery.js file.
I was wondering if it's possible to make an app which uses some cache or something (I guess the the page is saved temporary somewhere on the disk for the current session) to retrieve that data in vb.net?

all I want is a function like this:
[URL] but then with the option to provide username & password. I have managed to do this with the webbrowser, first logging in then go to webpage and get source code but this takes much longer than just getting the source code...
Is there any way to do this? I found this:
[URL]
I tried with &username=...&password=... in the URL but it didn't work

at the end of my public sub form1_load I have a line that calls another sub:Call DateRefresh()and this is what is in my DateRefresh sub [code] Basically all this is doing is tell me the days between february 9, 2009 and the current date and it displays it in a label named lblMessage Everything works fine but I need it to stay updated automatically. So after midnight it needs to update. It doesn't have to be right on the second. I was thinking I could set it up to update every minute or 5 minutes or something. The problem is I can't get it to update automatically.Maybe there is a better way to write the code as well so it will update.Im open to ideas/thoughts on this.In the future I would like to be able to, for example, have a user press Ctrl+D and it brings up a form to enter in the date (which is currently hard set at 2/9/2009) and it would update to an xml file or something/anything.

I'm making a web browser and want the url bar to update when you click a link, like it does in firefox or IE.
Private Sub WebBrowser1_DocumentCompleted(ByVal sender As System.Object, ByVal e As System.Windows.Forms.WebBrowserDocumentCompletedEventArgs) Handles WebBrowser1.DocumentCompleted
url.Text = WebBrowser1.Url
End Sub
When I try to compile this I get the error
Value of type 'System.Uri' cannot be converted to 'String'.
Anyone know how I can convert this so that it works?

I've got a class that closely resembles one of my entities (I use the class for JSON de/serialization because the entity fails conversion to JSON, one of the known gotchyas of JSON + MVC).Once I deserilize a JSON string into my object, is there a way to automatically update the associated Entity model instance. The property names are the same.
'myDeserialized is the deserialized JSON object coming over the wire
Dim entityInstance As DLL.Person = db.getPersonById(myDeserialized.id)
myDeserialized.update(entityInstance)

The primary key of the table is generated automatically using the Is Identity and I want to update based on the primary key. There is certainly something wrong with the following code, so I'd like someone to modify it for me.
Try
Dim qry As String

I have a web app which displays a list of emails that need to be sent for the day. The user can select what emails to send, then click a button to generate them. When they click the Send button, a process gets started on another thread which generates the emails, then cleans up after itself by deleting a temp folder. Once the process is finished, the Repeater is rebound to update the User's view and remove the emails that have just been sent so they don't get sent again.
My problem is that when I delete the temp folder from my 2nd thread, the UI doesn't update with the new Repeater data. It updates correctly if I just delete the files in the folder instead of the folder itself, and it also updates correctly if I run the delete the folder on the original thread instead of the 2nd one.
New Thread code
Dim t as Thread = New Thread(New ThreadStart(AddressOf EmailLetters))
t.Start()
Delete folder code
Dim fs = Server.CreateObject("Scripting.FileSystemObject")
fs.DeleteFolder(Server.MapPath(".") + " mpEmailFiles")
Why won't the UI update to show the new repeater values when I delete a folder on another thread?
When you click the button, a thread gets started and a javascript load script starts executing which does a PostBack every 10 seconds. Each postback checks if the thread is complete and updates the Status label showing the result. If I delete a folder from within the background thread, the final update to the status label never occurs. If I remove the DeleteFolder call, it does.

I am trying to build a self-updating .NET application that will run in an environment with limited user accounts. No admin rights here. The application must run on Vista and XP, and probably Win 7 when it comes out.An X-copy deployment would be fine. I would prefer NOT to use click-once.So far I have tried a system where the application checks a manifest and downloads updated binaries, which worked great in development, but not so much when the app was installed.Vista refuses to to let me copy files to Program Files. After that, I tried downloading an updated .msi, which works except that the MSI has a UAC prompt -- no go if the user does not have an account with local admin privileges.
running the program in AppData and using the x-copy method might work, but I have not seen anyone say that they have tried it and it did work. Will that work for an account without admin rights? Can anyone vouch for this method before I start writing more code?

I have develop a software which can run in different machine and when any update is available then it automatically update all the software dll and exe along with own.

I followed an example from a VB 2008 Wrox book on creating, binding and updating a data set but I am having a problem. The code is supposed to automatically generate the update/insert/delete statements for me (according to the book) but when I call the update command, the data is not saved.
Here is my code
Code:
Imports System.Data
Imports System.Data.SqlClient
Public Class FrmAddExpenses
[Code]....
After the form is loaded, I change the EntryDate field (which is a DateTimePicker) and close the form which should save the change but it doesn't work.
