Hello,

I have developped an exe application from vb6 that i call from VBA
with shell statement. It works fine although runs quite slow when the
spreadsheet is large and the application has to deal with a lot of
comm. with Excel.

The application starts a form by wich all the actions are preformed.

I woud like to know if and how to transform the exe into a dll, so
communication with excel should be faster

Any guidance will be very appreciated

Notes:

My knowledge in class stuff in VB6 is quite elementary
In a previous post i've got strong recommendation to dll my
application, but due to a lack of knowledge, i have preferred the
straightforward and more easy exe way but paid with a lack of
efficiency
