Sometimes, a woman might suspect she is pregnant even sooner. Symptoms such as headache, fatigue, and breast tenderness, can occur even before a missed period. The wait to know can be emotional. These days, many women first use home pregnancy tests (HPT) to find out. Your doctor also can test you.
Microsoft Excel is a spreadsheet program included in the Microsoft Office suite of applications. Spreadsheets present tables of values arranged in rows and columns that can be manipulated mathematically using both basic and complex arithmetic operations and functions.
As a Microsoft Excel developer, you must often test whether a worksheet, file or folder exists, or if a particular file is currently open. You might also have to delete a file. On a computer that is running Windows, you can use the File System Object (FSO) object to test whether a file or a folder exists. The FSO model provides an object-based tool for working with folders and files. Unfortunately, the FSO model is not available on the Apple Macintosh (Mac).
