- After reading countless paragraphs on how Windows supports only
- a few means of data transfer between applications, I have come to
- the conclusion that if I didn't want to use DDE, I could use a DLL,
- and GlobalAlloc memory which could then be shared between
- all the applications using that DLL.
-
- My questions are:
-
- (1) If I GlobalAlloc in the DLL, and get a handle using one application,
- then another application accesses this handle, will I get the data from
- the first application UNDER WINDOWS NT? I know that it works
- under Windows 3.1.
-
- (2) Are global variables declared in a DLL shareable between
- applications under Windows NT? Again, I know it works under 3.1
-
- (3) If a DLL enters a message loop on behalf of an application, will
- that message loop receive messages posted to the application
- properly under NT? Once again, it works under 3.1.
