Load EXE and run from memory - is it possible in C# ?

[Just D.]

Hi All,

I have a question. I need to load some EXE file into memory and then find a
way how to run it from the memory without saving to disk. I know that it was
possible in C++ to execute any code already loaded into memory. What about
C#? Does anybody know how to do that?

The main purpose - to download a small installer from my www and then using
this installer to download some big installer (like SETUP.EXE) and run it
without saving to a client disk. That's a requirement, the purpose is to
keep the client always up-to-date and don't allow him to keep old installer
files on the remote machine. The small installer should test the remote
application version and understand what version is running to stop it and
update if it's needed.

Thanks,
Dmitri.

Why not use Assembly.LoadFrom? It can load assemblies from the web:

Dimitri,

AFAIK, This is not possible in C#. But, if this is a .NET application, you
may want to look into self-updating applications.

Thanks for these answers. That's bad, but the main SETUP.EXE is written in
VB6 and my task is to write an installer. I can use C++ but I don't have a
ready code to download installer from a password protected FTP server. I
have this code written in C# and want to use it.

What about InstallShield's "Install From The Web" technology for the setup
packages and a background C# app to monitor and remove the local installer
files? Would that work?

Also, did you ever get that VB6 app upgraded and moved into C#? (I have a
good memory... lol)

Hi Kyril,

Did you see that for VB6?-)
Also, did you ever get that VB6 app upgraded and moved into C#?
Physically it wasn't my application. I gave some recommendations..., and
that's all. It's still VB.s

(I have a good memory... lol)

That's a very good advantage...)

Looks like the same...)

That might help :-) I know for a fact that you can use InstallShield for
VB6, but this might be even more suited to your needs.

Sounds like a lot of places I have worked at. ;-)

You know, that is what I told my manager, and he said that it is different
in terms of pay. So I accept it. lol
