系统资源不足（Insufficient system resources）

What is GDI? What does GDI resources represent?

GDI+ is a subsystem of Windows XP, which is responsible for the

output of information on the display screen and print device.

It is a set of application programming interfaces implemented

through the C++ class. As the name implies, GDI+ is the previous

version of the GDI inheritance, for compatibility, Windows XP

still supports the previous version of GDI, but in the

development of new application program, developers in order to

meet the needs of graphics output should use GDI+, because the

GDI+ of the previous Windows version of the GDI was optimized,

and add a lot of new function.

As the graphics device interface GDI+ allows application

developers in the output screen and printer information without

considering the specific details of the display device, can be

some of the methods they only need to output GDI+ library calls

class complete graphics operations, the real work of drawing

by these methods to the specific device driver to complete, GDI+

makes graphics hardware and application isolation. This allows

developers to write applications very easily device

independent.

Simply speaking, when the application is running, memory need

a space to keep track, running the state of the program, for

example, the menu button, the cursor position and bitmap,

window state, store the information space has a proper noun to

describe, that is what we are familiar with the system of

"resources", and storage the information space is known as a

"memory block stack", you can put "heap" into the management

mechanism of memory.

Depending on the type of storage object, the system resources

are divided into two areas: user resources and GDI (Graphic,

Device, Interface, graphical device interface) resources. A

system kernel program "" management stack called the

user resource heap, used to store the state of the window, menu

position information; by the pile called GDI resources system

kernel program "" management stack, used to store the

brush, brush, palette fonts, graphics object information. The

user resource heap and the GDI resource heap are collectively

referred to as system resource heaps, which we customarily

refer to as system resources.

Under the Windows 9x system, Microsoft divides the system

resources into five heaps, in which the user resource heap

occupies three, and the GDI resource heap is two. Three user

resource heap are: 16 bit user heap, size is 64KB; 32 bit window

heap, size is 2MB; 32 bit menu heap, size is 2MB. Two GDI heap

are: 16 bit GDI heap, size is 64KB; 32 bit GDI heap, size is

2MB. Windows 9x's reason for designing system resources is to

make the old 16 bit program run on the new operating system.

In the Windows 2000/XP system, almost never touches such as

"insufficient system resources", the main reason lies in the

Windows 2000/XP system has no resource restrictions on the size

of the system according to the actual operation, automatic

allocation of system resources enough.
