Hi Dave, now after reading the article I'm more concerned about the escaping the apostrophes and I've parameterised the query.
Thanks,

Yeah, the Parameter class takes care of escaping any characters that need it itself, as well as checking for certain types of injection attacks.

You escape apostrophes with apostrophes.
For example, this string...
"Bob's Data"
...becomes this...
"Bob''s Data"
|
|
|
|
|
Ok, but is there a function to do it or do I have parse the string to look for the apostrophe?

There's no function to convert it for you. But it's really easy to do it yourself. Try using this...
Public Function StringToSql(sBuf As String) As String
StringToSql = Replace(sBuf, "'", "''")
End Function

Let me reiterate that unless you take Dave's advice, you'll solve the problem today, but have more grief in the future, because you're choosing to do things the wrong way.

Thanks Chris, your persistence have convinced me to take the rigth way.

i want a sample tutorial (or code) in vb.net that demonstrate on parallel port proghramming for doing simple program?????

That's rather vauge. What are you doing with the parallel port?

i want to connect a small motor (simple) to the parallel port and control it by using a vb.net program??
i want a sample program and howto connect it??![Rose | [Rose]](https://codeproject.global.ssl.fastly.net/script/Forums/Images/rose.gif)

Well, since this is a very specific, and relatively rare, project, you're probably going to have to do your own research. The "perfect" example, with everything you want, probably doesn't exist in one place.
I suggest Googling for "parallel port motor" for any information. You'll probably have to piece together your project from various sources.
You can start with this[^] one, right here on Code Project.

ok
i want a very simple code how to control parallel port so i can on/off the led only??
VB.NET

From a motor to an LED... There's nothing simple about it, no matter what you do. The parallel port hardware is completely abstracted from your code. You MUST have a Ring 0 .DLL to get to the hardware FOR your code.
You can find an example at http://www.logix4u.net/[^]. Be be warned, you STILL have to do your own research to get any example to work. Trial and error is the best teacher.

For the hardware connection to the parallel ports and some sample code in C, see this website:
http://www.phanderson.com
About half way down the page are some books/workbooks he wrote about connecting hardware motors and such to the parallel port and programming them with the PC. The code won't apply, but he gives some great circuits and theory. I have both books and they are an excellent intro to controlling stuff with the parallel port.

This is an all-volunteer effort. Making time sensitive demands like this is just plain rude. You'd get faster results if you Googled it yourself, something like "VB.NET get host ip address".
