VC++/ DLL question

[Vallurupa]

Hi,

I am calling one DLL by two different processes (Two exe files.) How can i do process to process comunication between two instances of the same dll.
I have to access the window handle here.

I coded like this .. it is not working
#pragma data_seg (".mydata&quot

HWND hStimWnd1=NULL;
char *test=" ";
#pragma data_seg()
In .def file /SECTION:.mydata,RWS

Is there any other way to declare the variables, which can be shared in the process time with the other processes.

Please help me

thanks

With the #pragma I use this to count process instances:

#pragma data_seg("Usage&quot
long Usage_Count = 0;
#pragma data_seg()

#pragma comment(linker, "/section:Usage,rws&quot

I'm not sure, that it will work for Your application.
Why not make interprocess communication with SendMessage()? You can enum all windows by starting/loading of DLL, find hwnd of your Processes and then use SendMessage()...
You could use CreateRemoteThread() for interprocess communication too.
