Hi,

I'm new to this web site but I'm very impressed already with the professionalism of it. I'm in need of making a Excel function which offers tremendous potential. What I need to do is call a function written in C, syntax:

EXPORT BOOL CALLBACK FormulaSearch (long len, double* n, char** refs, char** formula)
{
/* Basically function returns 1 if no problems occur and allocates a string formula to 'formula.' If the function fails then the function returns 0.*/
}

Function sits in a DLL called 'fsearch.dll'.

I want to call it through a Excel UDF with syntax =fsearch(range,targetnumber)

The UDF should spit out the formula provided by the DLL function and mop up any memory left over. If the function fails an error message like "FormulaSearch" failed unexpectedly or something.

That's all that's needed. Simple huh?
