Tutorial Chapter 6th more user interfaces: Adding custom data in this chapter, we will describe what the user interface section of the. NET API can do. We'll begin by introducing a custom context menu (shortcut menu). Next we will implement a modeless dockable panel (a real AutoCAD enhanced auxiliary window) to support drag-and-drop operations. Then we'll introduce the selection of entities through the modal form. Finally, we'll introduce the options
system code runs in a mode with high permissions, your application is running in a low-Permission mode. This protects operating system code.
Registers, visible registers in each mode, and functions of each register:
Arm has 37 32-bit registers, 31 of which are General registers and 6 are status registers. But at the same time,
Not all registers are visible to programmers. Whether the memory is visible (accessible) at a certain time.
The current working status and working mode of the scheduler.

After enabling the interrupt, use the assembly instruction Svc 0 to trigger the SVC interrupt and complete the task of starting the first one. Let's take a look at the SVC Interrupt Service function:__asm void Vportsvchandler (void) { PRESERVE8 LDR R3, =PXCURRENTTCB/ * PXCURRENTTCB point to the highest-priority readiness task TCB */ LDR R1, [R3]/ * Gets the task TCB address */ LDR r0, [R1]/ * Ge

Problem description:
The view-related display is drawn in the viewportdraw of the custom object. Why is the display not displayed when 3 dorbit (3D Dynamic Observation) is run? Is the display normal after 3 dorbit is exited?
After repeated tests, after a user-defined object is created, as long as the User-Defined Object attribute modification function is called, the corresponding object will not be displayed when running the 3dorbit command.
Issue
Our custom entity does all its drawing in the vi

Tutorials 2nd Chapter . NET AutoCAD wizards and simple user input in the first chapter, we use the class library template, So you have to join ACDBMDG by hand. DLL and Acmgd.dll are two references. In this chapter, we will use the AutoCAD Managed C # application Wizard to create. NET project, it will automatically add the above two references. Before you begin this chapter, you first have to install the O

compared with M-cam, AutoCAD three-dimensional modeling compared to simpler, more powerful functions.
UG features strong modeling, design, processing can be integrated, the early stage of analysis, simulation, can connect, this is the strongest is no other software can be compared, if you are in a factory to do modeling files. The mold partner. The processing file turns to turn out, you can think of UG is how good.

degree of optimization. Compared to the previous optimization methods, it is a simple and effective way to optimize the program by setting the compiler option.
2 Code size optimizationAn important feature of the simplified instruction set computer is that the instruction length is fixed, which simplifies the process of instruction decoding, but can easily lead to increased code size. To avoid this problem, consider taking the following steps to reduce the amount of program arm code.
