If the RecordStream class was public, what could you do that you can't do now?
Note that Record.GetStream() or Record.Item on a stream field actually does
return a RecordStream instance, it just calls it a plain Stream because you
shouldn't need to care what kind of Stream it is. Every single property/method
in RecordStream is just overriding the Stream member, so there's nothing there
that isn't callable.

Subject: Re: [WiX-users] DTF Stream Operations Issue
Shouldn't matter. I can get the data to and from the file with no issue.
It's just trying to get the data into the memorystream instead f the filestream
is an issue.
The RecordStream object in DTF looks like it might be useful, but in typical MS
fashion, the useful foundation classes are internal instead of public, LOL.
I appreciate your help. I'll just keep banging on it from here.

Ok, I was wondering how you were going to read binary data into a string. I'm
not the best C# guy in the world but I'll see what I can learn here. I am
wondering though, is your text unicode or ansi and would it even matter?

It's text, and I'm running as a custom action, so my database should already be
available.
I'm opening the view with a joined query, but getting the same data. I can get
the record fine, and I can get the stream fine, it's when I try to read from
the StreamReader wrapper that I run into issues.
I'm trying to read out the text data stored in the binaries table, then modify
it. I'm trying to avoid using a temp file if I can, since I only need it in
memory.

What is the type of script?
Eitherway, would this work for you?
Database db = new Database("C:\\TEST.MSI", DatabaseOpenMode.ReadOnly);
View view = db.OpenView("SELECT `Name`, `Data` From `Binary` WHERE
`Binary`.`Name` = 'ISXMLCFG.DLL'");
view.Execute();
foreach (Record rec in view) using (rec)
{
Stream stream = rec["Data"] as Stream;
}

using (StreamReader sr = new StreamReader(stream))
{
script += sr.ReadToEnd();
}
Gives me an ArgumentNullException when I try to read the stream. Am I missing
a step?
Is this stream not compatible with a streamreader?
