Did you see my work around snippet? I'm interested in getting some thoughts on
it. When I'm having problems calling the framework there is much more to
google and a higher expectation that it's my fault not the frameworks. I need
to figure out how to better vet my code without bugging Jason all the time.
BTW, I wonder if we should have a DTF-Users list since this is really .NET
discussions more so then WiX/MSI proper.

No, it's not, and actually, that was a remnant from a variation I tried.
I thought maybe ReadToEnd wasn't working, so I did it line by line and got the
same issue.
The exception is thrown from within the Read operation, I know that's where the
issue lies. :-) Good thought though.

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?
