return value from an exe

[torels]

Hi there

I wanted to know if anyone knows how to return a value from an exe. Like a DllCall.

Is this even possible... and if yes is it in AutoIt ?

I think it could be done by writing data to some predefined memory address and then read them so to get a $DllCallVar[0] kind of thing where the exe writing the data is the dll. And the one reading is the DllCall function. But this is very risky.

any other ideas on how to make it less risky OR by using any other method ?

thanks for your help

Eh? Like this?

Exit 1234

KK, using stdout. means you need to write the exe to return using consoleWrite.

ExeCall.zip

Contains an example, which just has:

ConsoleWrite ("Success")

If You unzip and run ExeCall.au3, you should get a msgBox saying "Success".

Or the other method is to write in a file or in the registry.

thanks to everyone

writing to a file or the registry was not in my options... I wanted it to be in the memory.

btw... what's Exit 1234 ???

When exit a program, an exit code is sent to the os. if 0 it is a natural exit, else it defines the exit code.

Within autoit, if you have defined the exit function it can be got by @ExitMethod, and describes simply why the script is exiting.

For dos it is something like %ERRORLEVEL%.

Read up on exit, I think what monoceres meant is that you can then read this exit code, but I'm not sure how.

It's done with the GetExitCodeProcess or using the built in autoit function runwait.
