So I was looking around the forums for how to do a successful Winsock program but noticed that there is an alternative way of creating connections, using system.net.sockets. Would you guys say that system.net.sockets has replaced Winsock? Is there a particular one that is better than the other?

View 5 Replieswhat i am doing is downloading headers from a web server using a tcpclient which works great the headers describe diffrent files and there are hundreads per file, if i download the headers and write them to a text file using a streamwriter it works great, but i need the headers to be in a text file depending on the name of the file in the header, so i need them grouped together, i am now using streamwriter to write the headers to seperate textfiles depending on the filename in the header but it is reallllyyyy slow for some reason, im not sure if it is because it has to load each file then write to it? i only have to append the new header to the end of the text file i dont have to open it up and read through it.
View 8 Repliesi have added a winsock control to my program. I know that vb 2008 dosent really support winsock no more but its needed for my project.Anyways i have form1 with a button that does "form2.show"This works as it should and opens form2 but when i add a winsock control to form2 then i get this error when i click the button to show form2
"An error occurred creating the form. See Exception.InnerException for details. The error is: Class not registered (Exception from HRESULT: 0x80040154 (REGDB_E_CLASSNOTREG))"

View 2 RepliesI am trying to code a client - server program. I have 4 winsock controls on my main form. The client is able to connect to a free one just fine, and can figure out if they are all in use. When testing my program, I found that when I try to send data through a socket, then send different data directly after, it jumbles the data together.
CODE:
That is the code I am using. When the client is connected to the server, and ready for data, it sends the packet "@Ab". When the server receives this packet, It is supposed to send the welcome alert, and then current events posted in the server.
On the client side, there is a message box that is supposed to show the welcome alert, and at the bottom on a status strip, the current events are supposed to be listed.
When the welcome alert shows, it contains the alert text fine, but then shows the packet for the events after it.

View 3 RepliesThe code i have so far inputs the users username and pas that they inputted into 2 textboxes. Next the user hits login and it submits the info. Here is where i have a problem. Some users are already logged in when they get to the site, this is a problem because i need to make sure they are logging in correctly. Here comes another problem, lets say they log in correctly, how can i know that the login was successful?
Simplified:
1) How can i find out if the user is already logged in so i can log them out.
2) If they are not logged in, and they log in successfully. how can i confirm that?
If there is any other way to login without web browsers?
'Code to enter the user and pass into the webpage
WebBrowser1.document.GetElementById("Username").InnerText = TextBox1.Text
WebBrowser1.document.GetElementById("Password").InnerText = TextBox2.Text
'Code to click login on the webpage
WebBrowser1.document.GetElementById("submit").InvokeMember("click")

View 11 RepliesI've been at this for a bit now, and I have tried using google extensively. I have my application set up: it is a HWID System available only to paid subscribers. I want buyers to be able to click on a 'buy now button', and once they successfully pay it automatically adds their information into the database the app uses. This way there is no waiting after payments. I know this is possible, because I've seen it done before - I just can't seem to find how it works?
View 1 RepliesI have a sub that I just discovered does not work for my windows 7 users but works fine for my windows XP users. This is basically a sub for a ping monitor to ping devices on a timer. What happens is that when the windows 7 user tries to ping, it always reports "down" on a windows 7 whether actually up or down. But, windows xp will report correctly with "up". 3 different windows 7 boxes, users say it worked before. Can't quite debug correctly as i'm on xp myself and it works just fine. Also, I haven't changed anything in the code in quite awhile and this is a recent bug that just started.

I also want to be able to show the IP address in Text box 3 that the computer is using at the time.
