I have been in a process of rewriting all my VBA code to C++ to create a XLL
file. for increased speed and security. The problem I have come across is the
process of merging cells together. Can someone direct me in the right
direction on how to do this. This is not a COM it is a XLL file and using
Excel4 for macro calls. As there is very little information out there on
working on things like this I have been unable to figure out how to do this.

If anyone knows how to do this or has a sample they could put up it would be
greatly appreciated. Thanks in advance
