After calling define_external from maple library succefully loaded. But how to unload it without closing maple? For example want change library file to new one.

tryed to compile samples\OpenMaple\cmaple\omexample.c in MS Visual C++ Express 2010. Everything is OK but after running is writes "The program can't start because maplec.dll is missing from your computer..." Why? I've linked maplec.lib statically! Besides \Maple\bin.win\ in my library path where both maplec.dll and maplec.lib are. System - Win7 Home Premium +SP1

There is a enought complex function H(y) of one variable (includding definite integrals and 3 parameters). One needs to solve equations like that H'(y)=H''(y)=0 and build surface in parametrical space with respect to such solutions. Straightforward method leads to 'Warning, solutions may have been lost' for solve command. How to reformulate problem to become it solvable?
