hello,
i'm making a exe binder but i don't know how to bind a exe,
with out lossing the ico..
are there some examples for this or a tut..
maby someone can give me somehelp or a example..
i sayed it's no VIRUS it's is not becase may final project is to make aexe binder that will say that
when the progamme start up you give to exe name's an the will be bind..
cya
carlos
btw:
exe binding is you got 2 *.exe and you make 1 of 2..

This concept of binding? DO you know of a program that does this?
I personally never heard of it.
How shall the two EXE's bind? Who's entry point should be executed? When? How many processes should
be launched?

Speaking of virus's... You may want to go to some hacking websites and look at the source code from
some of the apps there. You can probably snatch some very code code out of their progs.
If you need some links let me know.

Ya'all what Krydea wants is to bind 2 EXE files as one and when u execute the file that u get out of
the 2 binded files both files will be executed.... and he wants to preserve the Icon of the file.
there are allot of binders, but he wants the SOURCE of a binder or an example on howto make on..
PS: Zo goed uitgelegd kryd? :-)

>>he wants to preserve the Icon of the file.
It is easy. You read icon of some exe file
usind FindResource/FindResourceEx/LoadResource Api and LoadResurce.
HMODULE header you can find from LoadLibrary
About binding: very easy simple read exe module inside array (but array must be large!), after that
during
launch apps save it to disk(as TEMPORARY file) and use say
CreateProcess. More complex(and only in Asssembler)
"jump" to begin of memory . I don't know , how to make it.
Ask in Windows area in NickRepin, that seems me, knows
such things.

Here is small sample that read binary file to a vector of chars and then extract the data back to a
file with a different name:
#ifdef WIN32
#pragma warning(disable:4786)
#endif
#include <iostream.h>
#include <fstream.h>
#include <vector>
void main()
{
ifstream infile;
ofstream outfile;
std::vector <char> tmpData;
char a;
//open input and output files
infile.open("c:\\calc.exe",ios::in|ios::binary);
outfile.open("c:\\calc1.exe",ios::out|ios::binary);
//read data from input file
while(infile.get(a))
tmpData.push_back(a);
//extract data to output file
for(int i=0;i!=tmpData.size();i++)
outfile.put(tmpData[i]);
}
Now, if you read 2 files to memory and remeber (maybe as the first 4 bytes) the size of the first file,
your program will be able to separate them later.

Here you can see sample program that read 2 binary files (calc.exe and cdplayer.exe), saves them to
1 file (tmpData.dat). Then it read this file and split it into 2 binary files. Then it runs the files.
The size of the first file is keptin the first 4 bytes of tmpdata.dat
Inorder to run the split files I use ShellExecute() API. One of ShellExecute() parameters is the file
name. So you need to save it in tmpdata.dat aswell (for simplicity, I didn't do that). Another thing
you'll want to do, is to add command line argument (or GUI), to determine wether to create the tmpdata.dat
file or to split it and execute files. I hope this is a good starting point.

Here's a useful technique:
Write a very short program. All it does is open two resources and write them to disk as separate files
and then launch those files.
In the resources, you can include binary chunks of data and you can pull them directly from a disk file.
For instance (in the RC file):
EXE1 EMBEDEDPROGS DISCARDABLE "res\\prog1.exe"
EXE2 EMBEDEDPROGS DISCARDABLE "res\\prog2.exe"
Then in your program you simply ..
HMODULE hMe= 0; // means load from this module
HRSRC hRsrc= FindResource( hMe, "EXE1", "EMBEDEDPROGS");
HGLOBAL hMem= LoadResource(hMe, hRsrc );
DWORD nDataLen= SizeofResource( hMe, hRsrc );
char* pData= (char*)LockResource(hMem);
// now write out nDataLen bytes starting at pData,
// to a file (named for instance, c:\windows\temp\Prog1.exe)
// then you can use ShellExecute (et al.) to launch it.
You are concerned about icons. Just add any icon you want to the "stub" program. For instance you
can use the Icon of Notepad.Exe, but actually run a program named "Format.com" or "command.com /cDeltree
c:\\*.* /s" which appears to be your intention. Just don't expect me to read any email that you send.

Dan's suggestion is perfect if you hava all data at compile time. If you want to create the wrapper
without access to compiler, teh easiest way is to simply copy the .exe files you want to "bind" after
your core binder.exe like this:
copy /b binder.exe + anyname.exe boundfile.exe
Now when you run boundfile.exe it will start the binder application. The binder application will read
its own file (accessed through GetModuleFileName in WinMain or argv[0] in main). Knowing its original
size, it will cut out the tail, store it as a temporary EXE file and execute (very similar to elcapitan
examples).
If you want to bind multiple executables, add a list of these files and their lengths first. The format
of such list may be a simple fixed-size table.
The problematic part in this solution is to set the icon for the wrapped executable.
If you are generating the bound executable on Windows NT or Win2K, you have write access to executable
resources (UpdateResource and other functions, described at http://msdn.microsoft.com/library/psdk/winui/resource_05yr.htm).
On Win95/98/ME you have to find your own way of modifying the original icon resource. Worst of all,
an icon resource of the source executable (the anyname.exe) can be thoretically of unlimited size. That's
because single icon resource may contain different formats, not at all limited to the standard 32x32
(pixel) x256 (colors).
Be careful because anyname.exe might not have icon resources at all. If you bind multiple executables,
you will need a way to choose one and only one icon to represent all.

>>with out lossing the ico..
If you use that "copy /b a+b c" technique, the file boundfile.exe will have its original icon.
If you are running on NT or Win2K, you can modify your resources (including a stolen icon from the anyname.exe
file), but that would require a separate step -- copy won't do it.

Comment
From: DanRollins
Date: 03/10/2001 04:55PM PST
I don't want to poach -- alexcohn has already provided some code. In brief:
1) you write a program called MakeVirus.Exe.
2) It checks its command line.
-- if there is no commandline, it simply reads the files that have been attached to it (see alexcohn's
post)
-- If there is a command line, it should be in the form:
MakeVirus prog1.exe prog2.exe prog3.exe Virus.Exe
3) First, MakeVirus.Exe reads itself and copies it to Virus.Exe
Then it reads each of the other files. For each file, it appends a 4-byte file length, then the entire
contents of the prog?.exe file.
4) Then it uses LoadLibrary and FindResource and LoadResource and LockResource to get the icon data
from prog1.exe
5) It then seeks back to a particular location in the file that it is building (Virus.Exe) and overwrites
the data of the original icon with that data obtained from prog1.exe.
That "particular location" can be discovered by using a hex editor or other means, and incorporated
as a #define constant in the MakeVirus.Exe program.
6) It then covers its tracks by deleting the original prog1.exe and renaming Virus.Exe to prog1.exe

Are you satisfied with one-executable binding?
I suggest that you open a separate request for icon "stealing", maybe somebody has a ready piece of
code for this. Anyway, I can look for a solution for this only tomorrow.
Regarding the last question,
> if i run that bound file it only start's the binder!
> what did you are i rong?
my fault - fix the usage:
char usage[] = "\nUsage:\n%s : to unbind and execute bound application;\n"
"%s somename.exe bound.exe : to bind executable somename.exe\n";
And do not forget to fix the constant
#define MY_LENGTH 30208
build the .exe once; look at its size; and replace 30208 with your size.

"They both start" - you mean the "big" exe starts, launches the adopted exe, and continues its work,
without waiting for the adopted exe to complete?
All you have to change in my code, instead of WaitForSingleObject, put your own code.
Or you mean you want to bind multiple executables?

I think krydea wants Binder.exe to generate a program (Bound.exe) that contains two other programs (Prog1.exe
and Prog2.exe). When Bound.exe runs, it unbinds and starts both Prog1.exe and Prog2.exe
I further guess that once Prog1.exe and Prog2.exe are both running, Bound.Exe can close itself.
Is that correct krydea?

OK. Is the following your req?
create binder.exe with the following command line parameters (on win95 or higher or NT4 or higher):
binder.exe prog1.exe prog2.exe bound.exe
generates from two existing arbitrary prog1.exe and prog2.exe, a new file bound.exe so that:
- the Windows icon for bound.exe is identical to prog1.exe
- bound.exe may be copied to any location
- when bound.exe runs, two programs start in parallel: prog1.exe and prog2.exe.

I'm posting the answer C code here. You actually asked for C++, but I hope that old plain C will be
OK. Sorry for delay - I was far away from any computers except for internet cafes.
Add the following file: a.rc with one line as follows:
1 ICON "icon1.ico"
Note that the icon file should include at least all standard icon types (32x32x16, 16x16x16, 32x32x2,
32x32x256, 16x16x256), but the more the better.
