View 1 RepliesCommunications :: Program Stalling On Network Reading?
Oct 8, 2008I am playing with network sockets as I need to work on a client-server application. So I have tried this simple code from VS help:
Code:
Dim tcpClient As New TcpClient()
'The following line do not belongs to original code 'But I needed to add it as debugger told me that 'I couldnt getStream from closed sockets
tcpClient.Connect("127.0.0.1", 8000)
Dim netStream As NetworkStream = tcpClient.GetStream()
If netStream.CanWrite Then
[code]....
So, I supposed that the code above would write the message to the loopback IP (127.0.0.1), it would be kept in the network buffer and would be spited out when it readed the same loopback IP. However, when it gets the line whre it should read the stream, the program just stalls and keep reading it forever. I have tested the stream with as if it was just awaiting for something to read. I have tested the stream with getStream.DataAvailable and it returned me False, what makes me guess that the data is NOT being properly written to the IP.
Firstly I thought that it could be something with the loopback IP, then I tried to provide the machine local IP (192.168.2.25) but I got the same behavior: code stalls...

Communications :: Write Program That Will Upload A File To A FTP Site That Has SSL
Jun 19, 2008I'm trying to write a vb.net program that will upload a file to a FTP site that has SSL (explicit, although I'm not sure what this means).The sample code and explanations I've Googled always assume when it's SSL that I'm using a client certificate. But I have no certificate to load.I simply need to login, accept their certificate and upload my file.When I accept their certificate am I actually installing it on the client? For example of FileZilla a box pops up and I just click on accept, then my login is complete.

View 1 RepliesCommunications :: Write A Program To Ping Computers On Network To See If They Are Turned On?
Jul 4, 2008I am trying to write a program to ping computers on my network to see if they are turned on. So far i have the following:
Code:
If My.Computer.Network.Ping("192.68.0.5") Then
MsgBox("Computer is on.")
Else
MsgBox("Ping request timed out.")
End If
If i use ip addresses, this works fine but i would rather use hostnames due to the ip addresses being dynamic (something which is outside my control). Using the hostname, it reurns "Computer is on" if the ping is successful, but if the hostname cannot be found, instead on returning "Ping request timed out", an error occurs as follows:
A first chance exception of type 'System.Net.NetworkInformation.PingException' occurred in System.dll
Communications :: Send A Command Via RS232 Communications
Jan 26, 2009I am using VB2008 Express and am curious how to send a command via RS232 communications. The string that I need to send is 02h PON 03h. The start and end bits are 02h and 03h.
How can I convert 02h and 03h to its ascii form. In hyperterminal, I use the sequence {(hold)ALT 0 0 2} on the number pad to send the start bit.
I am using this code currently without the start and end bits

Build A Program That Has A Dropdown Menu?
Oct 18, 2011I am trying to build a program that has a Dropdown menu (Combobox) where you select between a list of items like
xbox
ps2
ps3
wii
then once you select one of the options the program will bring you to a new window (In the same window) with a new box that has a list depending on which word you chose earlier. As an example.
If you chose xbox on the first window it will bring you to a window with a new list like
fighting game 2009
fighting game 2010
fighting game 2011
then if you select fighting game 2011 you would get another window that showed a list that had a list of characters from that game.
Guy One
Funny Hat Guy
Big Nose Guy
Dead Guy
Beast Thing
Funny Turtle Thing
Then in the new window you get a selection of options for the character you selected.
Special Skills
Combo Moves
Unlockable Content
Then if you select one of those you get a new window that has the lists. for example.
If you chose Special Skills show the list of special skills like the following.
Uppercut: Down + Y
Face Smasher: Back, Forward, B
and maybe beside the list of moves it could display an image of a Screen shot that shows the move (Or not if it is too complicated).
