I. Concepts of function calls
_ Stdcall, _ cdecl ,...... Left passed through the stack. The called function clears the memory stack of the transfer parameter before returning, but the difference is the function name modifier section (the modification section of the function name will be described in detail later ).1. _ stdcall is the default calling method of the PASCAL program. It is usually used in Win32 API. The function uses the stack pressure method from right to left and clears the stack w
. Explains the cause of status management.
There are two kinds of conventions about the dynamic library output function: The call convention and the name modification convention. 1) Call Convention (calling convention): determines the order in which function parameters are transferred to and from the stack. The caller
Ace, and through it to complete a project design, the project has a total of about 120 drawings, of which about 40-50 schematic diagram, other for the report, wiring diagram, terminal row, etc. We used to design a similar project about 3 weeks to design, 2 weeks to proofread, and the use of Ace after the design of proofreading a total of 3 weeks to complete the task, and achieved very good results.

(1) Call conventions there are multiple function call conventions supported by VC ++ 5.0. Here we only discuss the following three types: __stdcall, C, and _ fastcall. the _ stdcall call convention is equivalent to the Pascal call convention that is frequently used in 16-b

Call conventions (Calling convention) RefersProgramA protocol established to implement function calls in the design language. This Protocol specifies the parameter transfer mode in the function of the language, whether the parameter is variable, and who handles the stack. Different Languages define different call conventions.
In C ++, in order to allow Operator Overloading and function overloading, the C ++ compiler often rewrite the symbol names of

As the Windows 7 and Windows 8 systems gradually mature, more and more users (especially my girlfriend's hour, often used, in order to help her work ), windows 7 and Windows 8 systems are divided into 32-bit and 64-bit systems. Therefore, when you choose to install the CAD version, you must first determine whether your system is 32-bit or 64-bit!Some friends may ask, How do I know whether my system is 32-bit or 64-bit? Here are some tips for you!1. Click "my computer" on the desktop and right-cl

Let's look at an example: how do we combine conditions to select all straight lines on layer 0 and all circles with a diameter greater than 10?
Let's take a concrete example: Let's say we want to select all lines on layer 0 and all the circles with radii greater than 10. 'S how we wocould compose the conditions, in pseudo-code:
Layer = "0"
Entity type = "line"
And>
Entity type = "circle"
Radius >=10.0

Autodesk is crazy. It was sold out during a big jump. We had to buy n sets of AutoCAD Civil 3D, but now we only need 6000 pieces. :) I will not sell them, just take this opportunity to introduce the AutoCAD Civil 3D product.
AutoCAD Civil 3D can be said to be a 4-in-one product. First of all, it was built based on AutoCAD and contains all the functions of AutoCAD. I have seen many people use this product as an advanced AutoCAD product, haha.
