Thomas,

Before you go down the C++ route, why don't you post the code. There are
many techniques to improve performance woithout writing C++ XLLs or DLLs.

Hi,
excuse my cross-posting, but I do not know which NG is the appropriate for
my problem.
I wrote an Excel-Macro in VBA which reads a text file, interprets this
file
and then does in Excel what has to be done: format cells, put values to
it,
storing files, inserting worksheets etc.
This works well, as designed, but is not very fast.
So I look for a way to increase speed.
I have Visual C++ 6 in Visual Studio. Can I rewrite my macro in Visual C++
so that it gets faster? If yes, where do I find "easy to understand"
descriptions how to do this? What do I need additionally?
TIA
