I want to create a macro that allows me to search for particular string in a worksheet of a closed workbook. The idea is to have a textbox on a form in which I can type in a string, "something". The macro would then try to find such a string in sheet1, for example, in a closed workbook. If this string is found, it will report the name of the workbook where this string is located. I will have this routine in a loop to read any number of workbooks to perform this search routine. How to accomplish this? I don't even know how to start.
