IamlaosongLooking at a simple loop program, after VBA reads the data from the database, you need to enter a summation formula in the last cell:The formula means cells (i, 9) = Cells (I, 6) + cells (i,7) +cells (I, 8), where rc[-3] represents the formula in the same row The first 3 columns of the cell.How do I represent the first 3 rows in the same column? Very simple, with r[-3]c on it. And so on, the same row after three columns is rc[3], the curre

First, the standard module does not support events, and the object module supports event procedures.The standard module itself is not an event process, which means that you want to write the event process, never write to the standard module, of course, you can not write in.2. A standard module is a stand-alone container in which global variables, function
