HOW TO: Get Windows Status Information from Windows API in Excel 2000

In Microsoft Excel you can programmatically obtain system status information and display it in a worksheet. This step-by-step article provides a sample Microsoft Visual Basic for Applications Sub procedure that displays the following information by using Windows API functions:

• The Windows version number with the GetVersionEx API function.
• The CPU processor type with the GetSystemInfo API function.
• The amount of free memory with the GlobalMemoryStatus API function.

5. On the Tools menu, point to Macro, and then click Macros.
6. Click SystemInformation, and then click Run.

The macro returns a message box that shows your system information.
