I am trying to figure out a way to connect 2 users within my VB.Net application.The goal would be to send strings/integers/booleans from one computer to another that could be translated on the other side. The effect being a multiplayer game, or a chat box or anything of the sorts.If I wanted to connect to a computer here in the office, I couldn't because I can only connect to the shared IP and not the local IP's...

I'm trying to write a method in VB.net so that when I click a button it queries the database and returns all the values which match a textbox which is located next to the button. I have no idea how to do this, I assume in the onclick method for the button I will need to pull in the value from the textbox, connect to the database and display the results to a gridview?

I am having a problem with my 64-bit Windows 7, where a program I am creating in class (well, a group of us are creating) will not run on my 64-bit Windows 7.I know that problem stems from the Microsoft Jet OleDb connector, and that it's only for 32-bit windows and does not work with my 64 bit (and is not even listed in the Data sources page of the admin tools in 7).So, what can I do to resolve this problem? is there any way for me to connect to the database?I know the connection string is on this line:
<connectionStrings>
<add name="PrioritySystem.My.MySettings.systemDatabaseConnection"
connectionString="Provider=Microsoft.Jet.OLEDB.4.0;Data Source=|DataDirectory|\UserData.mdb"

I am a wannabe programmer but quite new, started with VB.net about 1 month ago.I write on this forum because It's the first time that I'm actually stuck. The problem is I cannot find a way to connect to SQL server database I have created and saved earlier on my HD using visual express 2010. I want to find a way to connect using code, not by click and drop. I just hope you won't find my issue too trivial to even answer it.The project is very simple, it just consists of a button that should connect to the db on click.[code]
