I've never come across this exception message before, so I'm guessing that it is becuase Access does not understand named parameters. So remove the parameter name. i.e.
cmd.Parameters.Add(firstValue)
cmd.Parameters.Add(secondValue)

 Of course, The MSDN documentation for OleDbCommand[^] confirms that.
Because Access uses positioned parameters rather than named parameters I thought you didn't need the name. Apparently, according to the documentation I linked to above, you do. Anyway, the docs above should give you the help you need to get going again.

The error i found what was the problem!!! whoever got this error:
the apdateable error .. go to Tool, Folder Options, View Tab and then uncheck the last one which tells you: Use Simple FIle Sharing. Uncheck it. then go to database file and right click on it, properties. then go to security tab and make write allowed!!! for all users!! then you can use the database to write in it. have fun!

Hai everyone,
May I know how to update a cookie using VB.NET. I received a message saying 403 Forbidden when I request for a web page programatically and I found on the web that it is because the cookie is not updated, sadly that person didn't specified how to do it in coding wise. Thank you.

When you say that you request a page programatically, do you mean that you are using something like HttpWebRequest to get the page? In that case you have to handle the cookes yourself. If one response contains cookies, you have to send those along in the next request.

Guffa, thanks for the speedy reply. Yes, you are right, I am using HttpWebRequest to get the page. This is my first time dealing with cookies, can you let me know what's the syntax to send the cookies? I'd added the cookies in the container CookieC.Add(LoginRes.Cookies) and when it reaches this line LoginRes = LoginReq.GetResponse(), the error message pops out, I guess here is where I should send the cookies again.
Thanks

Ok, I just realized how to do it, so I guess I better post it here. Before the line
LoginRes = LoginReq.GetResponse()
I put
LoginReq = Net.WebRequest.Create(domain & "menu.php")
LoginReq.CookieContainer = CookieC
to send the cookie again that is to fill up the container again, so it became
LoginRes = LoginReq.GetResponse()
LoginReq = Net.WebRequest.Create(domain & "menu.php")
LoginReq.CookieContainer = CookieC
And it works, the page is being loaded, thanks for the idea, Guffa

what is the use oops implementing in .net programming
|
|
|
|
|
"Oops" is something you say when your programming mistakes causes some kind of damage, for an example accidently erases the contents of a database table. Oops should preferably not be implemented at all. 
What I think that you mean is OOP, object oriented programming[^].
The .NET framework is an object oriented platform, so the programming languages used with .NET is object oriented.

Well, I sincerely hope that you are joking. If you are not, then the number of Namespaces/Classes/Assemblies available is pretty big. And, if you want to list them, the best approach would be opening Visual Studio and hitting F2 to open the Object Browser....

Is there anyway you can write functions in DLL's in VB that can be declared using the Declare keyword or is there any way to add references to DLL's using code. If you can please explain how to do either, I'm completely useless when it comes to DLL's.
