keeping global variables alive in xll

Visual C++ General

A7Zulu

am having some trouble keeping my global variables alive. At the top I have some excel floating point arrays declared

LPFP deposits_zero;
LPFP swaps_zero;
LPFP futures_zero;
LPFP fra_zero;
LPFP blend_zero;

Now I have a function that is called that sets the deposits, swaps, futures, and fra curve with an array that is dynamically allocated.

deposits_zero = USA_CREATE_SWAPZERO(0,0,0,0,curve,&tmpBlend, 1, 1, 3, 0,0,0);

It creates a curve, the function is supposed to dynamically allocate my that array.

Now later on in my code, I have a function that uses all 4 of those arrays that were set by previous functions. The problem is those arrays aren't there anymore. Whats my problem

I am also having trouble getting my Visual Studio to debug my XLL.


Thanks,
Aaron

This is a Visual C++ forum.

Try asking in an Excel forum or Visual Studio tools for office forum.

i am more or less having trouble understanding how memory allocation works. if i declare global variables in my xll, then i have accessors and mutators. I should be able to pull out a value that a previous function stored. but instead everything is disappearing. also what happens when things are multithreaded are there multiple instances of the xll in memory

thanks

Simple Samples

Try to describe the problem more in terms of C++ and less in terms of Excel. I am sorry, but I don't see a question about C++.

i have a global pointer, in a function i malloced some memory for that pointer. then in another function i access that memory but its not there. is there something regarding multithreading that i should be concerned about. is there something i am overlooking thanks
