RE: [GD-Windows] Adding custom resources to exes/dlls etc...

[Warrick B. <War...@po...>]

Aaargh! and I've just realised that BeginUpdateResource etc.. don't work on
Windows95/98/Me.  Will I have to manually load the exe file and add my
resources? - what problems will I encounter in doing this?

Thanks,

Warrick.

Hi,

I'm playing around writing a program to add custom binary resources to an
exe/dll.  I've read through all the documentation on resources but I still
seem to be doing something wrong.  The situation is as follows:

My program seems to update another exes resource fine (BeginUpdateResource()
etc...), I add the resource as a RT_RCDATA and it's language as a neutral.

If I then go to enumerate the resources attached to the updated exe I get as
far as the name of the one I've added (I actually get it's name and type)
but then if I try to enumerate it's languages I get an  error saying the
resource name is not valid.  If I try to use FindResource on it, it fails
with an invalid name as well.

Looking through the MSDN docs more I'm beginning to think that I need to
prefix my raw data when I add it in UodateResource() with a RESOURCEHEADER
header structure.  Also I'm worried that I have to be careful with alignment
and does the SizeofResource() function include the size of the header into
it's result?

If this is the case it would seem nasty when I add a resource as I'd have to
allocate a block of memory big enough to hold the resource and the header,
put the header before it copy the resource data across and then write the
whole block to the resource - is there no way of incrementally building up a
resource directly?

Thanks,

Warrick.
