Hi!

In c# I use [DllImport("userenv.dll")] to fetch the
GetDefaultUserProfileDirectory
But there are a LPTZStr and i don't know what the equalient is in c# for
that.

Anyone who can give me a code snippet on how it should look to import this
function?

Regards

Martin,

Your declaration would be:

[DllImport("userenv.dll", SetLastError=true, CharSet=CharSet.Auto)
static extern bool GetDefaultUserProfileDirectory(
string lpProfileDir,
[MarshalAs(UnmanagedType.U4)] ref lpcchSize);

You can also get a lot of the declarations you need for Windows API
functions at http://www.pinvoke.net (there is even an add in for VS.NET
which will do this for you).

Hope this helps.

This is wrong, see Mattias' declaration instead.
