Hello,
********************* basicly i want this:
=-run the app1.exe that controls for example Notepad and post a WM_QUIT to notepad.-=
[continued] ;-)
I am working on a WAY to send a message from my FIRST window to a OTHER aplications MAIN window.
For example i was trying notedpad BTW the CLASSNAME=db 'Notepad',0
I am planning to build some kind of intelligent tool that can START and STOP various stuff
in Other aplications. I am just lazy and don`t want to work in 4 apps when i can AUTOMATE tasks.
If this could work REALLY interesting things could be made; combine OUTPUT/INPUT from different
applications that are running by posting messages to them.
see my code what i mean.

I am verry sorry but the file strcpy.asm i can`t post it due to copyrights.
You can if u have visual c++ 6 get the strcpy.asm file and port uhh rework it!
It contains the routines strcpy and strcat they return a buffer in eax!

It contains the routine: strlen, it returns len in hmmmm eax or ecx!
Some help would be cool becouse i am a little stuck here!

Thanx again Vortex!
what if i use openprocces to open the running proccess of notepad.exe.
I mean how do i detect a running process?
Its the next step I need to take. :-)
Then i can first send some text the normal way to notepad and then open the process memory
and replace it INmemory with openproccess etc.
I have thoughts about learning more about process memory and how aplications use that.
Stretching the os to see whats loaded.
If i am some time ahead i can then hook/read/write to system memory.
The purpose could be to write driver code that does not need to be a service or a vxd.
I am verry fasinated with OLD DOS, and any way i can make a hack to get interupts working SHOULD BE explored!
Bye for now my friend!
