EDIF bug

[Phi]

Hey.
While programming DarkSocket, I came across a bug which means unless DarkSocket is created in every frame in an app, running any a/c/e will fail.
Attached is an example.
PS: Don't use this MFX, DarkSocket users! It may have servers, but I haven't debugged those yet!

EDIF was rather heavily modified by me in an effort to debug this error, but I will provide the source code if needed.

As with anything else - reproduce the problem in a fresh copy of the original template, send me the source and I'll fix it.

[Phi]

I've reinstalled the template and the problem persists; I'll see if a fresh extension continues with the bug.

[Phi]

Yep, the problem persists with the template object.
Attached is all the code you need.

Hi Sortacore,

I tried your application and i got 3 messagebox,

Conditions Ok!
Action Not Linked!
Expressions Not Linked!

and after press ok in the last one, i get the crash

Hope its helps!

To confirm the bug, copy the mfx to MMF2\Extensions, run MMF2 and load the mfa. Then press Run Application.
If the bug does not exist, you will receive a "Conditions OK!" message box and nothing else.
If it does, you will receive "XXX Not Linked!" message box(es) and the program may crash.

The problem seems to be SDK() is running when the sub-application object loads the application in the 1st frame, and switches to the 2nd frame, without ~SDK() running in-between.
In chronological order:
1) Application runs
2) Object runs SDK()
3) Object runs Extension() <<< Links a/c/e
4) Sub-application loads application (1st frame)
5) Sub-application causes object to run SDK(), but not Extension()
6) Sub-application switches to 2nd frame. <<< ~SDK() not run
SDK() is run in

I modified the extension to log all the function names to a file.

Note that there is no point where a Free(), ~Extension() or ~SDK() is called.
