If there is an ID with Rhino phone reference surface is better, in fact, the ID is also can be modeled, and the degree of freedom of the rhino than ProE, so the ID model faster than MD, but the ID to pull the mold and disassembly of the lack of understanding, may be built out of the surface and the actual some of the d
to observe.2.3 Debug Tool DebugDebug Tool debug is available in both DOS and Windows operating systems. Debug is a debugging tool designed for assembly language, which provides a very effective debugging method for programmers by means of single step, setting breakpoints and so on. It can be used to observe and modify the registers and memory units of the CPU, to keep track of the program's operation and to discover the program errors.In the experimental building environment, the DOSEMU is used
I remember some time ago, when I first came into contact with software cracking and reverse engineering, I tried many methods for some software to track button messages without knowing where, that is, they could not be broken, in the system module, the system often gets dizzy and gets nothing.
The MFC program is a common type of program. I calmed down and studied the message process of the MFC. After figuring out the source Committee, everything suddenly went on, and found that tracking the MFC
addition to F5, there are two ways to start, one is "Step Into" (F11), and the other is "RunCursor "(Ctrl + F10 ). The former automatically stops at the first statement of the main function after the debugger is started, and the latter stopsExecute the statement where the cursor is located and interrupt the operation (for example, I am a friend of mine :)).

After Debugging starts, the MSVC interface is changed to display the debugging-related window. These important window

Tip 1: Get the current instruction address and add the instruction

there is a virtual function, the first place to add a hidden member variable, virtual function table pointer, and then to the normal member variable. And then we'll see what it looks like in the virtual function table:A virtual function table is also an address that holds a virtual function for each item in 4 bytes. The address of the saved virtual function is discharged in the order declared by the function, the first one holds the virtual function of the first declaration, the second item hol

very good extensibility.Example and source codeWe take a simple toy factory, for example, the factory produces children's toys, girls ' toys and boys ' toys, first write a Itoy abstract product interface used to define the basic behavior of the toy model, and then implement the interface to generate a few toys specific product class Childrentoy,mentoy and Womentoy class:Itoy.classpublicinterface IToy { /** * 名字 */ String getName(); /** * 价格 */ float price(); /**
If you see the Webcenter Space app (Webcenter.ear) from the WebLogic console, the session timeout (3,600 seconds) session timout is misleading and is not applicable in the case of webcenter space applications. If you update the value from the console, it does not affect the session time-out of the Webcenter space application. Then, the question is how can I change the Webcenter space app session timeout? The default session timeout in Web. XML is set to 45 minutes. There are two ways to change t
Sony PS VR device okay
Virtual Reality device PS VR for the price of 399 U.S. dollars, and officially sold in October this year, PS VR needs to be matched with PS4. PS VR uses a 5.7-inch OLED screen with a resolution of 1080P (Monocular 960x1080), the refresh rate supports 90Hz and 120Hz, the field angle is about 100 degrees, and the delay is less than 18 milliseconds.

nested function in one step. If you use "Statement-by-statement" for calls similar to Func1 (Func2 (), the debugger enters and executes the function Func2 in one step.
In the local code, if you want to enter and execute specific nested functions in a single step, use the "single-step execution of specific functions" command in the shortcut menu.
When you want to return a function that is inside the function call, use "Jump out ". "Jump Out" will always execute the code until the function return
Plt, got, pltgot
I recently learned about linux advanced debugging technology. The following is an experiment on dynamic library connection.
First, we understand that plt is procedure linkage table, and got is global offset table. The got table stores external symbol addresses. The plt table stores the function address. Next, let's take a look at the lab details.

code and disassembly code to study the process of the MFC message, find out all the sites of the MFC message path, in this way, all message events of MFC can be located at will, and the processing process of MFC can be tracked and analyzed from any site. You can even start from the pumpmessage base camp and keep track of the entire process.
