dumb question (maybe).
Is "script" null upon entry into the loop you gave?
It can't be as far as I know for the += operator to work.

Re: [WiX-users] DTF Stream Operations Issue
I haven't seen a WiX developer yet that wasn't helpful and open. I'm
impressed with the fact that the entire team is very active in this
mailing list.

As an aside, we do have the source code to all those internal classes :)
And more importantly we have a developer who in the very few days I've
known him has been extremly open and cordial in addressing questions about
the classes and even taking suggestions from improvement from such an
obvious C# rookie as me who happens to have a bit of domain knowledge the
classes are trying to address.

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?
Christopher Karper <[EMAIL PROTECTED]> wrote:
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;
}

Stream stream = binRec.GetStream("Data");
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?
