Hi
this is my first mail to this group. I hope this group will be helpful
for me.

In Labview , What is the difference between .dll files and .exe files
in terms of how they call during the execution and in terms of memory
management.

Please reply

The main difference is that an exe is a stand alone executable and a DLL is a collection of functions as they were implemented in LV. That allows you to write a function in LV and call it from another language.

Using either of them will invoke the LV run-time engine (which takes an X amount of memory, depending on the version and the application). Each instance of the LV RTE is limited to a certain amount of memory by the OS (I think the official limit in 32 bit windows in 2GB, but you would probably hit that before). I think that if you open a DLL while running another executable in parallel would open a second instance of the RTE, but I'm not sure.
