I have problem as follow, I have excel files itch in different folder, named as "source11" ( in one dir) and "report11" (in other dir) ( e.g for November) , Every month I copy and rename them as "source12" and "report12", and in some cell in "report12" write number, 12, it need also to change links in "report12" to refer to the "source12". I have 4 different excel files and I do this every month. In one of my previous application, I have problems like, .exe file and excel file must be in same dir, but I need to start an .exe file from any location different from excel file location How can I do this with an VB application, Thanks in advance
