Write to OLE embedded text file in Excel

Hello there

This is definitely a 500 point question.
I've written a large "object-oriented" application in Excel 2003 vba and this includes writing a lot of settings to a text file. I read and write the text files line by line and I'm quite happy with the way this works.
HOWEVER: One of the main incentives for coding this project in VBA was that the application should be self-contained, i.e. just the *.xls-file and no extra *.txt-files or any other "tag-alongs" to keep track of. So I have to get rid of the separate text file somehow. As far as I can see, there are two options:

1) Use a multiline text box instead: This, however, requires that i can perform read/write operations on the text box in a similar manner as I do with a text file. This does not seem to be possible and I don't particularly want the hassle with chopping up a huge string in substrings containing a lot of special characters and so forth.

2) Embed the text file in my spreadsheet as an OLEobject. This works, but how the h*** do I access it programmatically for read/write operations in VBA without opening it for the user to see? Working with such embedded OLEobjects in VBA seems to be a nightmare. The .open and .verb methods just open the damned file for plain view.

I would appreciate any help here :o). I can't find anything useful on the internet.

Best regards,
Einar

If they are settings, why not store them in document properties, defined names, or even a hidden worksheet? (or really anything but an embedded text file!)
Oh, or the registry, depending on what the settings are?

Hi, Rorya

Document settings? I'm afraid I don't know what you mean by this.
The "settings" are both settings for my objects and data to be kept between sessions in general. I would very much prefer to avoid using a spreadsheet unless I absolutely have to since this means entirely rewriting the methods for reading/writing settings.

Ok. Seems that I will have to admit defeat and rework my functions since they store arrays as well as other data. Thanks for showing me custom document properties, though. Although rather limited in flexibility they might come in handy later on.
