I'am currently developing an internet dialer for my work and i'am on the part of dialing to the net itself using an ISP, my problem is when i use MScomm i can connect to the ISP server but i can't surf the RD and SD of the modem is not responding.

Also how could i set the proxy settings and username, password of the dial up? should i use wininet? or what should i use?

How can I solve this problem..

I Think I'm Connected... But How To...
I am pretty sure I am connected to my access database, but I cant get any information to display from my database, or enter info? here is the code I am using to connect:

ConStr = "DSN=MYDSN;UID=;PWD=;"
Set Con = New ADODB.Connection
Con.ConnectionString = ConStr
Con.Open

I get no errors so I do think it is connected, but I cant figure out how to access or add data? I think I'm close but not yet? any help would be great!

Who Is Connected To Me?
Good day to you, I am looking for a new add on for a program of mine, so I was wodnering if it was possbiel to see the IP addresses of people or machines trying to connect to me, like show them in a listbox or listview and if I click on them in the listbox it would block them. then when they click on one to be blocked, it gets added to another listbox that is a block list?

Can I do that?

Thanks !!

Am I Connected
hello,

i'm probably not the first one who is looking for this feature.

i'm seeking for a code that will check if i'm connected to the internet. regardless if i'm using lan or other network.

i looked a lot for such a code but all i could found was codes that :
1. were confused with the lan connection (showing online while offline because the check for lan connection and not internet connection).

2. halt the computer for too much time before they return false. (not reasonble period).

well, i hope you had better luck and found a good code. please send it to me, i really need one.

thanks

Is Connected?
any one here has a sample program for thes pseudocode

the program should detect your internet connection. The program should ignore your LAN (or any permanent network connection)

PHP Code:

IF CONNECTED
      MSGBOX "CONNECTED"
ELSE
      MSGBOX "NOT CONNECTED"
END IF

here's what i did

PHP Code:

if connected then

    Shell ("E:Program FilesICQNDetect.exe")
    Shell ("E:Program FilesYahoo!Messengerypager.exe -quiet ")
    Shell ("E:Program FilesMessengermsmsgs.exe /background")
else
   timer1.enable = TRUE
end if

See If IP Is Connected To Network
Hello all,
I have a few computers on a network.
I have a form that is a floorplan of the machines on the network, with a command button for each machine.
I use RealVNC to view and work on these machines.
Right now, when i click on a command button it starts the VNC program for that machine.

What i'd like is, if there is a way, when the form loads(preferably) or when i click on a command button, it checks to see if that machine is connected to the network before continuing. If it is not connected the button that represents that machine changes color.

If it helps VNC uses port 5900. and the IP's of the machines are all under the same subnet.

I am very new to visual basic and I use Ver. 6. If anyone could please help I would be thankfull.
Thanks in advance.

Winsock Who Connected

If Not Connected To The Internet...
OK, I need to check for the presence of a LAN based internet connection.

I have tried every code I have seen on this site as well as others.
I've used many different API's, none passed this test.

1.) I run the code, It says I'm connected. Perfect, program seems to be working.
2.) Then I pull the network cable out of my cable modem, Insuring that I have in fact lost my internet connect.
3.) I run the code again. EVERY ONE of them I've tried still say I'm connected.

4.) SOLUTION: None of them actually work as advertised.

DOES ANYONE HAVE CODE THAT ACTUALLY WORKS PROPERLY?

If so please let me know
email me: spot10@attbi.com

LPT1--Anything Connected To It?
I've got an application that users run, say Start.exe, and two other applications, say Proggie1.exe and Proggie2.exe. Start.exe checks the users system and if certain criteria are met, it starts Proggie1.exe, otherwise it starts Proggie2.exe. One of the criteria is to see if there is a printer connected to LPT1. Is there anyway that I can check to see if anything is connected to LPT1?

Winsock, Connected??? Help!
I was wondering if you could help me on checking if the server is started or not.

so that I can make a offline/online function..

I have tried this:
Winsock1.Connect "192.168.46.12", "8866"
but don’t know what to do now, I don’t know if the connection is made or not.

How can I check that?

Connected To Internet?
..or not...

I found this code, but it doesn't seem to make any difference if I'm connected to the internet or not.

VB Code:
Private Declare Function InternetGetConnectedState Lib "wininet.dll" _(ByRef lpdwFlags As Long, ByVal dwReserved As Long) As Long

VB Code:
If InternetGetConnectedState(0&, 0&) = 1 Then Call CheckSourceUpdate End If

I think it's getting confused as I'm behind a router. Is this the case or is there another way of testing?
The problem is that any Inet commands hang if there is no connection.

Thanks

Network Connected
Hi there everybody - I'm new to this forum, just joined today.

I'm developing an application that uses SQL Server via a mobile computer. Sometimes the notebook will be connected to the SQL Server via the network, but at other times it will be disconnected and using the MSDE installed on the local machine. There is a limitation in the SQL Server DMO library function ListAvailableSQLServers - this will only return the correct listing if a live network cable is physically plugged in to the computer (or a wireless network is available).

I need to be able to detect wheter or not the network is connected before calling the SQL-DMO library.

How do I do this?? I have scoured the net for help, but nothing pops up for VB6. For VB.NET or C, no problems....

Appreciate any help that is forthcoming....

Thanks!

Connected To Internet, (is Really)???
Hi folks,

I needed to find if a user is connected to internet or not. And if so report the duration.

I used the ping command to find if the connection is available or not. Worked all right.

But, now I find that my client has removed the dialup connection mode and installed DSL. Here all the clients in the LAN can share connection, the moment it is available.

The problem is that every time I ping I get the value as true as the connection is always available. Thus, even though the guy might not have used the connection the report shows that hs was connected.

Guys help me out!!!

Check If Connected
what's a good code (I have vb 6, learning edition, without Inet)
to check if somebody = connected/disconnected with the internet?

Users Connected To PC - Who?
Well not in a programming way but you could run a command shell

then type Netstat, this shows all the IP connections in / out of the machine

also typing in ping -a <vaild ip> will try to resolve the host's name

Connected To Internet?
hi all,

does anyone know the best way to check for an active internet connection?

this is not as stupid as it seems...

1. loads of scripts use the registry, which is though not compatible under different win OS (one i found does work with w98 but NOT with w2k);

2. loads of scripts verify lan or dialup or adsl connections, but not all simultaneaously.

does someone have a clue on how to do this?

hope you can help out.

best regards,

w.

Who's Connected To Your Machine?
U know when you go to shut down a 98 machine on a network
and get a message "There is one or more users connected to
your machine, shuitting down will disconnect these users, do
you want to continue?"

Is there any way in VB to check what machine name, or IP
address, or better still username is supposedly connected to
your machine?
