Yes this info can be stored along with the cabinet file. But this information will not be recognised by programs that uncompress cabinet files such as WinZip. We must create our own archival program for uncompressing such cabinet files.

you don't need any software to read these files because Windows Explorer can read them itself

RE: Cabinet DLL code errors
Vimil Saju (Feb 19 2001 7:27AM)

The code isn't as complicated as it looks.
There are only 3 functions that are required to compress files. The list of functions exported by Cabinet.dll and the parameters of each function are available in the download section of the article. you only have to get an idea how each function works. I will add the decompress routine as soon as possible.


The first one is

FCICreate
This function returns a context (a unique value) which is required in the remaining functions.It works almost in the same way as GetDC function in Win32API which returns a context. Using this context you can change a lot of attributes of the DC such as its background color. (The GetDC function and FCICreate are totally different functions that use the same approach to change properties)

the next function is

FCIADD

This function is used to add a fileto the cabinet.To add more than one file,call this function more than once.

FCIDestroy

Once you have added all the required files to the cabinet,you have to call this function to release the memory and delete temporary files created by cabinet.dll.

I have attached the list of functions exported by cabinet.dll and how to use these functions. There are actually two units. you should copy each unit into a separate pas file and then compile them. I would be grateful if you could send the list of errors to my email address 'vimilsaju@usa.net'
Thanks for your response.

Hi Vimil,
First I've to thank you as I appreciate your work and use cab files.
I succeeded in compressing cabs and also decompress, but I have an error message after the successfull decompression: access violation at address 0045472D in uncab.exe etc.
Her's the code I use for decompression:


procedure TForm1.Button3Click(Sender: TObject);
begin
  if not(cabdecompressor1.Processing) then
  begin
   cabdecompressor1.CabPathName:='setb.cab';
   cabdecompressor1.TargetPath:=('.\decomp\');
   cabdecompressor1.Files[2].Select:=True;
   cabdecompressor1.Decompress;
   end;
end;
Have I forgotten something?
Best Regards,
Philippe Marechal - Cannes  FRANCE
