Urgent:How to create a .exe file from a MEL script ?

[hnf]

I would like to ask you for a help in answering my urgent question.
Q: how to create a .exe file that would automatically install a MEL script (how to create a stand-alone .exe file that would automatically execute a MEL script) ...?

but I don’t want the code (script) to be shown. To be more precise, I want my script to be a stand-alone .exe file that once opened it is executed (and if possibly, I want the Maya to be loaded simultaneously)

I'm not sure if it's possible (for a Maya end-user) to pass MEL code to Maya from an external program. You might be able to start Maya up from another program but I doubt you can directly send MEL commands to it.
If you just want to hide your code from others, you should consider coding a plugin instead of a script. You'll need good knowledge of C++ and the Maya API.
An idea is to write a Maya plugin that can read files that your executable program writes MEL code to. Not a recommendable tactic but it might work :p

Sunder is right,
If you don't want to share your code you need to build the script as a plugin so it is precompiled prior to launching in Maya. You could build in a piece of code to execute Maya.exe but from then you would need Maya to run your plugin. I know if you are to just test things as a script you could add it to the start up scripts dir/ and from there you could add a line in your initial script sequence to run that procedure.

I am not sure how to launch those from a plugin. It has to be able to be done because when you run a plugin like Syflex you get a menu which is a simple mel command each time you launch.

One little thing to think about is to make sure the user loads the plugin.

The good news is that you can make plugins for free. Get VSC++ from the microsoft site and then install the mayaPluginWizard. That will let you create maya project from with VS, and it will let you compile straight to a plugin format. You just set it to compile into the plugins folder, and then you can load the plugin from the plugin manager. I used this to create a quick hello world app just to see if it would work. I didn't get much farther than that because I didn't know enough about C++ at the time. I might give it a try again. Check this out:

Note, you will need to know about C++ classes as other advanced stuff you may not know if you programming experience only includes MEL.

If you have the newer versions of maya, you can write python-script plugins instead of C++. It's easier in my opinion.
