I have Visual Basic .NET 2003, and have also been working with another programming languages which has file mapping capabilities - aka, it can create named blocks of data which can be accessed by multiple programs. Does anyone know whether Visual Basic supports file mapping, or, if it doesn't, where I might be able to find a library with this capability?

Thanks in advance...

how about xml?

if you know nothing about xml, read the first link on this page.
http://www.vbdotnetheaven.com/Sections/XML.NET.asp

if you know something about xml, here's an example of how you write it to a file in VB .net

here's an example how you insert into an xml document that exists already.

there are lots more on reading, parsing, etc on that page. go to it.


can't go wrong there, in .NET you can write out xml easily to a file and read it back into C# or pretty much any programming langauge you want. not sure if this is what you meant, but its the way to go for flat files.

No, this isn't what I meant. I know some XML, and I agree - it's a great way to create files that can be read by most programming languages.

However, the "file mapping" I'm referring to is a method of storing a block of data in some form of higher memory, I think - not on the hard drive - where other applications can access it. Here is the explanation in the help file of the softwarel:

The programming language is Dark Basic Professional - it's a very powerful software, with lots of built-in commands that are simpler than using more traditional programming languages, but its GUI capabilities are greatly lacking, so I was hoping I could integrate it with Visual Basic...

Wow! Thanks!

http://weblogs.asp.net/rosherove/arc...5/01/6295.aspx

This link has a wrapper somebody wrote for accessing shared memory - assuming it's in VB, I may have just found the solution!

Thanks again for all your help...

EDIT: Oh crap! I just upgraded to VB .NET Express Version, the new one, and I don't think the wrapper will work now... dam...
