Hey all
I have a .xll plugin that registered a few functions which we use in our excel sheets in a number of places. The performance was very poor, and we didn't have the original code, so we replicated the functionality by writing the functions in VB in a module. The functions work as expected and performance is much better.
The problem is the sheets do not automatically recognize the new functions. For example, suppose a cell's formula is "=CustomFunction()" which was earlier defined in the xll, and now has been defined in the VB. This will keep showing as "#NAME" unless I manually edit the cell, and press enter. It then correctly picks up the VB formula and calculates.
The standard tricks of recalculating formulaes : Ctrl/Alt/Shift/F9 haven't worked.
Has any one experienced this? Any idea how to solve this?
