I would like to search an online (internet) database and import the result in my own Windows program. As I understand from reading and searching I first have to do a get from the default (search) page to get the cookies for instance and then do a post providing the filled input fields and adding the previously collected cookies. So far getting the information seems to work but submitting the data back to get the actual search result doesn't seem to work. This is what I have so far: [code]Anybody that can point me in the right direction? I my assumption correct that I first have to do a Get and then Post the correct data back?

View 1 RepliesI'd like to use the webrequest webresponse method to test for the existence of a file.If the first file is there, then I want to test for the existance of the same filename with -1.htm appended to it. If that filename exists, then test for filname-2.htm This continues until the filename being tested comes back 404 error. At which point, the program does NOT blow up, but the do until loop stops and the code continues. I have to search for a link on each one of the pages found once I have determined how many pages there are.How do I test for a file and not have it blow up? It has to loop and it goes through at least once. this is code I wrote. Right now the page just keeps going and going. IE's little logo on the page tab keep going around in a circle like it's in an endless loop.

I have a form with binding sources and a method for saving the data.[code]I was testing to see what would happen if the operator tried entering duplicate data in the primary key field. They exception occurred as I expected but the program gets stuck at that point. The exception messagebox just keep redisplaying when you click OK. I'm fairly new to .Net, but this code is how the help files show updating a TableAdapter using the "Try/Catch".

I am trying to write a little application that will help me monitor 8 websites sharing the same IP address.
The code that I am using to query the Status of the Websites is failing to report the correct status of the website; by status of the website, I mean, if it is accessible from any browser.
I got a timer that triggers the following
Private Sub Timer1_Tick(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Timer1.Tick
'Create a web request for site.
[Code]....
Basically the webresponse is supposed to turn the textbox5 color to "coral" if the website is up and running or accessible, and turn the textbox5 red if the website is down. What is happening is that all the time the timer is triggered, the text box5 turns coral or "good connection" even if I entered a website that does not exist, Then after 3 minutes I get and exception error that states: The operation has timed out.
Basically, I just need a way to query the site and interpret the response by turning the textbox5 to color red in case the website is inaccessible or down.

Then, when the user clicks on the link in the email, it either launches my program, or brings the program to top, depending on whether it is opened or not, and then loads the record for that ID number from the link (the software is a record lookup tool).If I can figure out how to "send" the program the ID, I can figure the rest out.

I have a win form with three textboxes that lets the user input information using VB.net 2008. I am wanting the program to send me the information entered (when they hit the send button) as an email and also drop the information entered into an access database.I have the program sending the textbox information as an email.What I am having trouble with is saving the three textboxes to access database. I have an access database set up with a table and three fields for the three textboxes.
All I need to do is each time a user uses the program, it adds the information they enter into the three textboxes to the three different fields in the database. I don't need to let the user view or edit the database in any way.
I am transmitting data over an IP socket and receiving the data via a second program I have written. The server was in VB6 and am now creating a new one in vb.net to run as a service. The major issue I am having is related to the encoding features.
Issue 1 to be able to correctly encode a bytearray so that when it is received by a VB6 program via winsock that the data will be in the proper ANSI format for the pc to read it correctly. So far this works on some files and not on others depending on the content of the file.
Issue 2 to be able to correctly encode a bytearray, send it to a vb.net host program and correctly [decode?] write it to disk.
To make things a little more complicated I must also be able to do this where the client resides on a Windows Mobile, Windows CE, or Windows PC. I have been running some tests and have gotten mixed results.
Is there anyway you can send information back to the original creator of the program? Here is a quick example- I made a little program that gives you general information about your computer, when you click a button it sets the text box to specific information. One of the text boxes gives you the Version of your OS. I would like to know if there is a way to send the information in that text box back to me when someone clicks it and they are connected to the internet. FYI I would tell the person who clicks it before so that I am not stealing information, plus what is there to steal from a simple program I made.
