I am trying to get the source code from a webpage. The WebBrowser control is giving me the information that I am looking for. However, I want to use HttpWebRequest, but its giving me different source code than the WebBrowser DocumentText. How can I get the same source code as WebBrowser using HttpWebRequest?
WebBrowser Code:
WebBrowser1.Navigate("[URL]" & txtUrl.Text)
textbox1.Text = WebBrowser1.DocumentText
WebBrowser Result: [URL]
HttpWebRequest Code:
Dim request As System.Net.HttpWebRequest = System.Net.HttpWebRequest.Create(url)
request.KeepAlive = False
request.Timeout = 10000
Dim response As System.Net.HttpWebResponse = request.GetResponse()
Dim sr As System.IO.StreamReader = New System.IO.StreamReader(response.GetResponseStream())
Dim sourcecode As String = sr.ReadToEnd()
HttpWebRequest Result: [URL]

My datagridview is successfully created with the following code in frmMain:[code]With the help of BackWoodsCoder I was able to add the datagridview column names to the X and Y combo boxes but that's where I get stuck again. The original source code appears to re-read the delimited text file instead of using existing object code.I did try the MapWindow Forum first but have had no response thus far.
View 1 RepliesI'm trying to "convert" an Access DB to a stand alone application. I have under estimated the differences between VBA and VB. Although I have many questions, I'll focus on this topic first.
The Access DB collects and maintains SNMP traps from a radio station. I import CSV files from a remote Unix server via FTP, parse the text line-by-line, and add to a table as a new record. So far, I can parse the text and add to a dataset but I want to write directly to the data source. I also need error handling that will trap errors for duplicate records. There is a Reconcile function that ensures that all lines in the CSV files are added to the table before the files are permanently deleted. Here's what I have so far:
Public Class clsRnm
Private msTrapTable As String

is there any working examples of implementing add/update/delete using the binding source?
i have a datagridview that has a bindingsource as its datasource and i am wanting to provide Add/Update/Delete functionality on the grid itself. Each record has a delete button which when clicked will remove the row and then add/edit is performed in the grid itself
the user then clicks a save/commit button that will then perform the nessecary updates on all rows
my initial plan was to have a copy of the data (iList) and then compare this to the contents of the binding source data to confirm whether to add/update or delete the record
also upon clicking the delete button i cant get it to remove the row from the datagridview. it thought i could do something like this...
Private Sub dgvDocumentTemplates_CellContentClick(ByVal sender As Object, ByVal e As DataGridViewCellEventArgs)
If (e.ColumnIndex = 6) And (e.RowIndex <> dgvDocumentTemplates.Rows.Count - 1) Then

I'm currently coding an ATM system in VB, and when a user picks a card to 'log on' with, they have 3 attempts to log on before the card is confiscated.
The card numbers are in a combobox (which are retreived from an SQL database using the binding source which is linked to a data adapter), and each card has a boolean 'confiscated' field in the database.
It does actually set the card to confiscated after the 3 tries, however I'd like the form to 'refresh' so the card no longer appears in the combobox, without having to close down the form and reload it. Is there a way to do this? I've tried refreshing the combobox and data adapter (.Refresh) but this does nothing
way to do the following in VB 2005:
I need to access, but not display, a web page out of a VB 2005 program. The web page would be an aspx page with a query string as part of the url - with the url using values acquired thru the program - e.g. www.mysite.com?arg1=this&arg2=that
So the aspx page would produce an html output with values I need placed in specific elements. I want to read that page from my app and do stuff with the resulting values.
In VS2005, how could you get the current web page's source in VB.net's webbrowser object? I need to load a webpage up, and then grab everything out of the header and body tags, and then I want to replace some text inside of those tags, and then reshow the page with the updated source.
