Connect Micro Controller To Internet Via VB Application?
May 29, 2012
i m currently working on application that has to monitor temperature and humidity of a particular place and constantly report the same to the user over internet. So far, I m using LPC1768 and its ethernet module collect the data, process it and send it to the router. On the other side, i have a computer which is connected to the same router and running a VB application where the data is mined and reported in a excel.
This setup works just fine. Now, i want to monitor the same data over internet. How can i do the same?
Here i was able to connect to the micro-controller using the IP 192.168.1.100 port 80. I m aware that the IP is a local one and to access the micro controller from Internet there is another way.I have a IP based webcam which enables us to monitor from internet. How should i make micro-controller data be accessible from internet.(similar to IP Camera).
I am connecting to a SQL database on a hosted server and everything is ok but if I publish the application then it fails to connect which is a bummer because then I can't debug it!
I have tried turning off windows firewall and that doesn't make any difference.
When I make an application using an HTTPWebRequest to connect to the internet, the GUI freezes whenever it's doing something. When I run the WebRequest on another thread, it still freezes a bit. Is there a way to completely stop the freezing?
I have finished a project with SQL database . Today, i introduced for customer , and they contented about my software. But they have a another shop and far away from current shop : 60 km so they want to connect to server from client at that shop. As far as. i haven't ever connect through internet. Please show me basic steps to do that. example :
I wrote a password storage app that uses cryptography to store password and user info. Each time I start the app either in the IDE or from Windows it attempts to connect to the internet. It is not supposed to connect to anything except a local Access mdb file. Nothing in the app has any need to access the internet. If I disallow the connection thru my firewall, I get the following exception:

For an answer to this questions I've been looking years from now, then I couldnt find it and now it's complicated. I am working on a project to fully manage a computer's connection, it can check IP, change it, etc. But, I really, really need a function to sucessfully connect/disconnect a PC from the ineternet without promps or other screens, IPCONFIG and DHCP command aren't useful!, im exploring RAS but couldnt come to anything yet
I have a small web browser application I wrote in VB.NET that is specific to it's use. To set it up, I have to setup port forwarding. Is there any way I can write another .NET app that runs on my dedicated server, accepts an incoming connection from my home PC that sits there. Then any other incoming connection from the outside world can then be connected to my home pc through the app on the dedicated server? If there is a term for this sort of process or program, I do not know what it is.

I have an internet available SQL Server 2008 R2 instance that is running normally. Clients connect over the internet from vs 2005 and 2010 desktop applications, without issue. My scan gun application can connect to the local instance (if I'm in my office) but not to the internet instance from my Windows Mobile 5.0 scanning device. Connect string = user id=[Code]. This connection string works fine for the desktop apps. It's not a port issue, I have all the correct ports open.
I have a very irritating problem with connecting to SQL Server/Database. I've created a windows form and connected it to the database on my server (connection string: "Data Source=KARIMOV-PC;Initial Catalog=ApplicationForm;Integrated Security=True")... it works well and without any problems!!But I when I tried to connect my application to the database through internet with connection string "Data Source=190.190.200.100,1433;Network Library=DBMSSOCN;Initial Catalog=ApplicationForm;User ID=KARIMOV-PC\KARIMOV (My computer name and windows authentication ID);Password=;", the "USUAL" message has appeared to me saying."A network-related or instance-specific error occurred while establishing a connection to SQL Server. The server was not found or was not accessible. Verify that the instance name is correct and that SQL Server is configured to allow remote connections. (provider: Named Pipes Provider, error: 40 - Could not open a connection to SQL Server)".
I really really need to understand why my own server "KARIMOV-PC" doesn't work as a remote SQL Server although the SQL Remote Connections and SQL Browser r enabled and running? And Why .\SQLEXPRESS is the more needed/required although I log in to SQL with Windows Authentication, but not SQL Authentication??
I'm trying to create a program that will disconnect/connect you from the internet.Example:When I press F10, I get disconnected from the internet. When I press F11 It connects me to the internet.

Older people who may find using a computer useful for things such as email, shopping, sharing photos and such like.
We have a VB.Net application which works fine in our tests in different Windows XP SP3 machines. However there is one machine in which is displaying this error:
Unable to connect to any of the specified MySQL hosts
Using the mysql command, we can successfully connect to the database. We already checked for any other application or firewall that could be blocking the connection but it seems fine. We also reinstalled the system (no errors during the installation) but the MySQL error message doesn't change.
The system settings are exactly the same as in the other computers. We are using "localhost" as server in the connection string. The "hosts" file has its default values (nothing strange in there).
I would like to create a program that could; open a website, log on to my account, scan a page for links, and open those links. The ultimate goal would be to reduce time spent checking things like e-mail or MySpace.
I found similar forum thread [URL], but he don't have answers. How I can conncect | send | recive data using tcp connection with specific internet service (not web).
When will VB be supported in the Micro Framework? it seames as there is a lot of new technology comeing out of MS lately leaving VB behind, insted of in step with C# like origionaly promised.I know that the VB compatibility dll has yet to be ported, but if this is the only hang-up, skip it for now and get some eary adopters playing with it.most of us can read C# so VB documentation is not hugely needed, just a few quick samples in the SDK.Please help, the company I work for could have soo many applications for this tech, but we are commited to VB for it's ease of use and it's natural synthax for reading.
I have build using the computer Performance counter a Stop Watch class with a precision of 1 Microseconds ( 1/1000 of a milliseconds )It works good but While building this class I had a problem And found a work around to it. But I am not please with this work around.As you may know, the CLR does not create it's object at the time where you declare them, but when they are first needed. So, while building a class that a timer with such precision, the elapsed time, you will get include the time used by the CLR to build the class. This is a problem since it takes 700 to 800 microSecond to do so.I have try using a code like the one I post here, try using start/stop method, try builing the class as native code API etc. And always the same problem,I get some CLR time include in the elapsed time.The work around I finaly found is to use the fact that the CLS will recycle an object if you dispose of an object and recreate immediately after.
So, what I do, is create the timer, dummy use it, dispose of it and recreate it to actualy do work with it. Here again, I get a small CLR work time of 3 to 4 Microseconds for recycling work.I have no hope to find a better solution using a managed code class, but I am sure that there is a way to put in memory from managed code, an unmanaged class that will be ready to be use by the managed code.If you try to run it, the first time you will click the button, you will get an extra 3-4 microseconds on the result.[code]
