How I can get system resources status?

No matter what Win 2000 always returns 90% because Win 2000 and NT and XP have pretty much virtually eliminated System Resources.

For Win 9x take a look at this KB from MS. Although it was written for VB it still has some very useful info. One of which there is not any direct 32bit call to the system that can be made to get this info from a 32bit application.

The Crazy One

If you have a 16bit version of Delphi then you could use the GetFreeSystemResources 16bit API to get the info.

Also you take a look at this link.

GetCommandLine() retrieves the command line used to launch your application.

GetComputerName() retrieves the network computer name.

GetDiskFreeSpace()retrieves information on free disk space.

GetDriveType() retrieves a specified drive type, such as fixed or removable.

GetLocalInfo() retrieves information on the specified locale.

GetLocalTime() retrieves the local time.

GetLogicalDrives() retrieves the drives available to the machine.

GetLogicalDriveStrings() Retrieves the names of the drives available to the machine.

GetStartupInfo() retrieves the startup information for the applications main window.

GetSystemDefaultLangID() retrieves the system default language identifier.

GetSystemDefaultLCID() retrieves the system default locale identifier.

GetSystemDirectory() retrieves the Windows system directory.

GetSystemInfo() retrieves system hardware information.

GetSystemTime() retrieves the current system time.

GetSystemTimeAsFileTime() retrieves the current system time in a file system time format.

GetTimeZoneInformation() retrieves time zone information concerning standard and daylight savings time.

GetUserDefaultLangID() retrieves the user defined default language identifier.

GetUserDefaultCID() retrieves the user defined default local identifier.

GetUSerName()retrieves the logged on network user name.

GetVersionEx() retrieves the windows version.

GetVolumeInformation() retrieves information on the specified volume.


Hope this helps you narrow down what your search.

Thank you for the answer. It works great!
