View 14 RepliesCheck If Connected To Internet + Image Available?
Oct 18, 2010Basically I want to have a picturebox which shows an embedded resource if not connected to the internet, and an online image if connected to the internet.I assume this can be done on the form load event, I just don't know the code for it. Basically this is the logic though:
-If 'http:/[url].... is available (therefore connected to internet)
-Picturebox1.Image = http:[url].....
-Else[code].....
How can I code that properly? Would putting it in the form load event work?

List Name Of All Connected Devices On Lan?
Oct 28, 2010i am trying to enumerate all IPs on my local network, but i am not having any luck. The only thing i have came up with so far is a really tedius "get my own ip and scan the subnet with pings" which surely isn't the best way? I am really only trying to get the ip of a tivo box, and i can determine it's a tivo by mac address or name. My router lists the "computer name" of the tivos as a long string of numbers with the prefix "tivo".What about broadcasting a ping packet? I could also attempt to connect with telnet to port 31339 on every one of them.

View 2 RepliesCan't Disconnect From CR-connected Database
May 30, 2006I'm viewing reports on a VB.net form using CrystalReportViewer. Once a report is opened, the Access database that is used within the report is locked (i.e., the Access MDB file can't be deleted). Even after the report is closed, the database stays locked until the VB.net app "ends". This is a problem because I want to be able to delete the MDB file at some point while running the app and can't. The VB.net app starts by opening a form named "Startup". No database connection occurs here. A button is pressed using this [code]I must not be properly closing the CrystalReportViewer or the Report form.How do I close the Crystal report and unlock/release the Access database?

View 7 RepliesClient Still Connected To The Server?
Aug 24, 2011My first post here in vb forums. I'm new to sockets programming since I migrated from Winsock and I learn a lot from Atheist. using his code, I can't access the messageReceived() every time a client sends a message on the server. but then I put a code to catch the message on sub doRead() and I can retrieve the message. My problem now is how can I determine if a client is still connected to the server or not so I can delete it on the ConnectedClient ?
[Code]...
Note: the server runs on Win7 x64 ultimate and the clients are laptops on win7 x86. I read a comment that the server should be having a static IP address, but when did it together with the clients, It still doesn't work. I am just using a switch for the network.
