I'd like to set the proxy for a web request. However, when I say, for example, request.proxy = "x.x.x.x:xxxxx", it gives me the error "String cannot be converted to webproxy". How can I get around this and actually set the proxy?

View 4 RepliesI have 2 applications that needs to talk to each others. After some research, I wanted to go with managed pipe (namespace system.io.pipes). The problem is, the client must send commands to the server but need to also wait for incoming message from the server at the same time. I tried to go asynchrone but it doesn't work.

I'm making a application to use in college to retrieve my calendar and other things in VB.NET. But my college uses a proxy so when I connect my laptop I need to change the internet settings in my web browser to view web pages. how I would send requests via a proxy server in VB.NET? Or is there a piece of software that I can download which tunnels all connections or is there a setting in win7 does this?
View 1 RepliesAlright I know that this question is asked all too often on vbForums but I am running into this problem and none of the posts have been clearly answered, a majority of them just redirect to some deprecated VB6 code that cannot be transferred easily to VB.Net. I was wondering if anyone would be able code to refresh my Local Area Network settings on a windows seven computer.I have code that will set all of the registry values that I need. (I have read on other posts that this is not the best way but then they just link to old non-.Net code that will not fit into my project.) I was wondering what exactly the 'Ok' button when you exit the LAN Settings window does, because this part is what actually refreshes the Ip of the computer to use proxy settings set by the registry values, I was hoping to have my program only be one button, that would do all of this without it opening the LAN Dialogue (requiring further human interaction.)

I am attempting to simulate a Mouse Click in Visual Basic, like the option where you can macro the mouse but not actually moving (i.e. it would click a x,y point while I am doing something else on the computer without moving my mouse, so its minimized still doing clicks. If this is not possible, is it possible with SendKeys function? If not, I know I can do it in Delphi. Another project is I need to add a Proxy Set to the IE embedded tool. How do I add a proxy set up where I can use proxies switching every time an event is called?

Looking for a basic UDP Pipe or redirector. Should of course be able to see both client 2 server and server 2 client data.Here is what I tried but it fails because I don't know when to call which Receive..Say I call
data = serverUdpClient.Receive(sender)
Then I have to reroute this, so I call this
clientUdpClient.Send(data, data.Length)
[CODE]...
Pretty much the code flow is all fucked.. because it's socket is blocking. When I started working on UDP.. all examples say stay away from non-blocking as it's too advanced for newbie's trying to work with networking sockets.. I find that statement wrong.. the other way around!.
Public serverUdpClient As System.Net.Sockets.UdpClient
Public clientUdpClient As System.Net.Sockets.UdpClient
Sub runProxy()

Also tried this.. doesn't work properly.
While True
If serverUdpClient.Available > 0 Then

I have a perplexing problem. I have written a DB App using SQL Express 2005 as the back end and Visual Studio 2005 Standard VB.Net as the front end. I have a master DB that needs to import from an external database from another SQL Express server. I detach the DB from that server and attach it to my server. I import the data I need, close all connections to the import DB and try to drop it from the server since it is no longer needed. Yet one active connection remains so I get a drop error. To get around this problem, I set the import DB to single user with roll back immediate and then drop the database. However, when my application tries to access the Master DB I get the follwong error
A transport-level error has occurred when sending the request to the server. (provider: Shared Memory Provider, error: 0 - No process is on the other end of the pipe.)

I have a lot of Microsoft SQL Backup files. The application should restore each backup-file with
RESTORE DATABASE {0} FROM DISK = '{1}' WITH REPLACE
Then I fill another database with some data from the restored database and drop the restored database with
DROP DATABASE {0}
If I only restore one backup-file, no problems. The data from this backup is in the new database and the restored database is dropped. But if i use more than 1 backup-file, i get this error:

Currently I am building an application that will do Data Validation on an Excel Spreadsheet.The application will allow a user to load an Excel Spreadsheet in and runs checks on the data. The application needs to export the spreadsheet as a pipe delimited file with all of the fields separated by the character.Currently I have written an Excel Macro that will export it as a Text File then delimit it and save the text file as a .ps1 file. I cant seem to figure out how to write this same code in VB instead of VBA.I am currently using Visual Studio 2010.Here is the code for my Macros that work fine but I need it in the application and not on the spreadsheet.

Just trying to get EXIF information using ImageMagick. If I set the variable command to:-
"C:Program FilesImageMagick-6.6.2-Q16identify.exe" -ping -format "%[exif:*]" "C:est.jpg" >c:exif.out
And then:-
Shell(command, AppWinStyle.Hide, True)
I don't get an exit.out file. There's a delay so it's clearly doing it. Obviously the same line from an actual command prompt does work! And I get an exif.out file... Any idea how I can shell that command off and get an output file?

Dim alltext, lineoftext As String
OpenFileDialog1.Filter = "Text files (*.txt)|*.TXT"

View 2 RepliesHow to make a vb.net application that allows me to play online games using web proxies?

Is it possible to set a WebBrowser control to use a proxy connection without changing all the other browsers also changing to that proxy?To clarify, I have an application that is monitoring a website but refreshing often enough during the day that I'm getting "you've made too many requests, please try again later". I'd like to get around that by using a proxy. Unfortunately not all anonymous proxies can be trusted for secure information like credit card information, so I only want to proxy the webbrowser control and not proxy any other non-application browsers.There is a site that explains quite well how to change the proxy (link not included, not certain on whether link posting allowed) but it changes the global settings on all browsers.I've tried to use 3rd party components (ex IPWorks HTTP control) however that doesn't work well with script-heavy sites that load and update dynamically - it only gets the empty skeleton of the page before being populated from the server DB.
