Problem with calling a DLL which again calls a DLL

[sudhir72]

i am facing one problem. i am calling a DLL with few parameters which in turns call another DLL.

the second DLL takes some time to return the results as it has to do many calculations.

the result i am getting is all zeroes. the creators of second dll say that you need to make first dll wait for results from second dll.

can it be done? if yes how

Wait how and for what? A synchronous call is blocking until the method called is finished. Are you asking how to use a thread for this? Or is the method asynchronous and leave the result in an instance property? If so it should also be having an event telling when the work is complete and result is ready.
