Hi,

Does anyone know any good library to work with DFM files? Any help will be
appreciated.

TIA,

Hi Mike,

Actually, I want to get a DFM file and be able to read its components and
their properties.
I tried with TStream, and TFiler, but everytime I try to use
ObjectBinaryToText to convert my Binary DFM to text, I get an error message
saying "Invalid Stream Format". Do you know how to solve this?
Sometimes I'll need to get 2 different DFM files, and check if they have the
same Component (for example), the same name, same ClassType, and eventually
check some properties...

TIA,

R Medeiros

The easiest method is to save your dfm files as text to begin with.

You mean, change its extension to a Txt? As it's a Binary file, I was trying
to use ObjectBinaryToText procedure that does exactly what you suggested.
But I was always receiving an error message: Invalid Stream Format......Do
you know how to solve that?

Starting in D5 the default format for a DFM is text not binary so more than
likely this is your problem. You are trying to treat a text DFM as if it were
binary.

Sorry, I don't think the DEFAULT was text, I am pretty sure the
default was still binary but could be set via (Tools | Environment
Options) and on the Designer tab, checking "New forms as text".

"I think" that it was the default in D6 though... but I may be wrong,
I don't remember (my brain is mush, for those Piers Anthony fans).

Even after making this change you still need to make a minor change to
the form to make sure that it rewrites the DFM.

James,

Thank you for your suggestion, but I had tried this before, and it didn't
work also.

TIA,

Brad,

Yes you are right. But I'm developing this application for Delphi 4 users.
They will not migrate to Delphi 6 now, for sure. So, I know that if they use
D4, their DFM files are in Binary format...Have you guys seen any good
library to manipulate DFMs?

TIA,

What exactly do you want to do with them that the IDE can't do?

Delphi comes with a CONVERT.exe routine which does just that (converts
from binary to text), for an easy one time fix (after that just use
the text files).
