"AppendData" command to append data to end of exe

[Mistrel]

I would like to see a command similar to DataSection but have the data be appended to the end of the file instead of being placed inside the exe section, something like VBin_ or DBin_ but without the need to append after compilation.

This would alleviate problems like this:

Here is a link to DoubleDutch's DBin_ code:

It would be *very* handy.

Do you mean something like this?

Code: Select all

Procedure AppendData(ExeFile.s, DataFile.s) 
  ; (c) TS-Soft
  Protected File.l, Pack.l, Size.l, *mem 
  If OpenFile(0, ExeFile) 
    ReadFile(1, DataFile) 
    Size = Lof(1) 
    *mem = AllocateMemory(Size) 
    If *mem 
      ReadData(1, *mem, Size) 
      CloseFile(1) 
      FileSeek(0, Lof(File)) 
      WriteData(0, *mem, Size)
      WriteLong(0, Size)
      CloseFile(0) 
      FreeMemory(*mem) 
      ProcedureReturn #True 
    EndIf 
  EndIf 
  ProcedureReturn #False 
EndProcedure

it seems to me more like a hack just appending datas to an exe file.

Also, I think, the initial request was to access the datafile in the exe-file itself.

[DoubleDutch]

It would be very good if this was a built-in system.

[ts-soft]

The idea is good.
If you use IncludeBinary, windows load allways the datas with the exe in
memory. Better is to solve this: Using Resources or Append Data.

With AppenData, if you insert an exe into your exe file, how do you do to extract it from your exe ?

Example : I've got an exe which names install.exe. I want it to include program.exe. I use AppendData, that's OK.
Then I want to tell install.exe to "extract" program.exe from it. How do i do that ?

Thanks in advance.

FileSeek Lof(0) - AppendDatalength !
I hope you can with this info write your own code

[GG]

Appenddatalength ? Where does it come from ? Sorry for my movice questions...

[ts-soft]

The length of the datas you have append! or write the length after the datas
and read this first on the end of the file and then seek back.

[GG]

Right, I'll try this, thanks a lot for your help and replies.

[DoubleDutch]

GG: Why don't you just use DBin? If it doesn't do what you want then improve it and resubmit it to the forum.

[GG]

Yes, thanks Doubledutch, I'll try DBin also.

[Mistrel]

For those who are interested, it would appear that UPX does not compress appended data. UPX will only compress data found in the exe section.

[DoubleDutch]

Didn't know that - thats handy.
