I try to find the example for reading data from USB Joystick using VB2010 but I couldn't. .
I found some but all were VB6.0.
Do I need to install DirectX or which component should I use. I can read data from mouse and keyboard.
I got an Arduino hooked up to the PC and would like to read the serial port of it. I read the serial port in Visual Basic with com.Readline, but it won't read everything. It looses around 2-3 lines that were sent over the serial port to the Visual Basic code. They get "lost".

I have a project where I added visually and successfully a datasource of MySql. I binded a datagridview with a table.
But, how do I change programatically the password, ip or user to connect with the MySql server? Because it can change at any time, so I can let the user change these values.

RshProcess.StartInfo.Arguments = "rsh..."

View 3 RepliesDoes anybody know which version of Visual Studio 2010 contains the full set of Visual Basic SharePoint Templates? I am about to embark on a project to create Visual Web Parts to be used in a SharePoint report.
At the moment I am using Visual Studio 2008 and even though the WSPBuilder is installed none of the relevant SharePoint templates are present.Having searched SO and the web, most advise to install the templates via the Visual Studio command prompt: devenv /installvstemplates
Alas the Visual Studio command prompt is also missing from my VS2008 installation.So, the question remains: which version of VS2010 contains what I need for pain-free SharePoint development? There is a rather large price different between VS2010 Professional and VS2010 Premium, so can anyone tell me if the cheaper version (VS2010 Professional) contains all the Sharepoint templates?

My students did a tutorial in HTML Help Workshop to add Help files to a VB 2008 Windows application. They zipped the files and uploaded them to our class web site.
I downloaded them at home, unzipped, and tried to check, but every one shows Table of Contents or Index and cannot find the .htm documents for the topic. The same thing happened in my office. However, these projects work correctly in our classroom
lab and do display the .htm files.
