Can I attach a hidden blob to a Word document

[Alex]

Hello,

Is it possible to attach a large amount of binary data (hundreds of KB to a few MB) to a Word document that will not be visible when the document is opened in Word but can be accessed using an external application?

I tried creating additional storages and streams inside the compound document but Word removes them when the document is opened in Word and then saved.

Thanks,
Alex.

You can attach document variables which can be arrays. You can only access
these through the Word interface, though; that is, through vba.

Hello Charles,

You can attach document variables which can be arrays. You can only access
these through the Word interface, though; that is, through vba.

Unfortunately, Word document variables are (a) strings, and (b) limited to about 64KB.

I need to store binary data an order of magnitude larger.
UUENCODing is not feasible.
