How can I know the number of columns and rows on excel file

[BABEMIN]

How can I read the number of columns and rows on an excel file after opening the excel file with ActiveX.

By using example of excel200dem, I read the data on excel file.

However, in this example, I just give the number of rows and columns.

I want to automatically know the number of rows and columns not giving those in C code.

Who know this things?-?

Help me plz.
