SUMMARY
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.

To get Windows status information by using Windows API calls, follow these steps:  Start Microsoft Excel, and then create a new workbook. On the Tools menu, point to Macro, and then click Visual Basic Editor (or press ALT+F11). On the Insert menu, click Module.  On the module sheet, type the following code: Option Explicit

Type SYSTEM_INFO dwOemID As Long dwPageSize As Long lpMinimumApplicationAddress As Long lpMaximumApplicationAddress As Long dwActiveProcessorMask As Long dwNumberOrfProcessors As Long dwProcessorType As Long dwAllocationGranularity As Long dwReserved As Long End Type

Type OSVERSIONINFO dwOSVersionInfoSize As Long dwMajorVersion As Long dwMinorVersion As Long dwBuildNumber As Long dwPlatformId As Long szCSDVersion As String * 128 End Type

Type MEMORYSTATUS dwLength As Long dwMemoryLoad As Long dwTotalPhys As Long dwAvailPhys As Long dwTotalPageFile As Long dwAvailPageFile As Long dwTotalVirtual As Long dwAvailVirtual As Long End Type

'The following three Declare lines must be each entered on a single 'line.

ver_major = verinfo.dwMajorVersion ver_minor = verinfo.dwMinorVersion Build = verinfo.dwBuildNumber msg = msg & ver_major & "." & ver_minor msg = msg & " (Build " & Build & ")" & NewLine & NewLine

' Get CPU type and operating mode. Dim sysinfo As SYSTEM_INFO GetSystemInfo sysinfo msg = msg + "CPU: " Select Case sysinfo.dwProcessorType Case PROCESSOR_INTEL_386 msg = msg + "Intel 386" + NewLine Case PROCESSOR_INTEL_486 msg = msg + "Intel 486" + NewLine Case PROCESSOR_INTEL_PENTIUM msg = msg + "Intel Pentium" + NewLine Case PROCESSOR_MIPS_R4000 msg = msg + "MIPS R4000" + NewLine Case PROCESSOR_ALPHA_21064 msg = msg + "DEC Alpha 21064" + NewLine Case Else msg = msg + "(unknown)" + NewLine End Select

msg = msg + NewLine

' Get free memory. Dim memsts As MEMORYSTATUS Dim memory As Long GlobalMemoryStatus memsts memory = memsts.dwTotalPhys msg = msg + "Total Physical Memory: " msg = msg + Format(memory \ 1024, "###,###,###") + "K" + NewLine memory = memsts.dwAvailPhys msg = msg + "Available Physical Memory: " msg = msg + Format(memory \ 1024, "###,###,###") + "K" + NewLine memory = memsts.dwTotalVirtual msg = msg + "Total Virtual Memory: " msg = msg + Format(memory \ 1024, "###,###,###") + "K" + NewLine memory = memsts.dwAvailVirtual msg = msg + "Available Virtual Memory: " msg = msg + Format(memory \ 1024, "###,###,###") + "K" + NewLine

MsgBox msg, vbOKOnly, "System Info" End Sub  On the Tools menu, point to Macro, and then click Macros. Click SystemInformation, and then click Run.</ol>
