A question about calling MATLAB from C

Hi Mr./Mrs. I am now doing a project requiring me to use MATLAB as a part and call it from C(VS2008). Specifically, I use mcc to create the corresponding dll,c,h files and include them in my C code. However, when there is a fhandle in the MATLAB code used to call other functions(e.g. A.m), there is a problem using the dll,c,h files in C and the problem is the function A.m cannot be found! Would you please give me some instructions on how to solve the problem? Thank you so much!
