Article #20090: System Resource Capacities in Windows 95

Running out of system resources in Windows 95 can give the Delphi exception "EWin32Error" with further details such as "in VCL40.DPL". EWin32Error is raised when Windows returns an error code. Following are some Windows 95 limits. The logical pens and brushes limit is probably the most significant for Delphi users since it will limit the number of visual components an application can create simultaneously. These were found on the Microsoft web page at: http://msdn.microsoft.com/library/winresource/dnwin95/s70b0.htm
