inside the JVM.So what internal information can JTI provide? Simply put, the Java debugger can get any information, JTI can be obtained, this is because the Java debugger is based on JTI write.For two examples, the following are the two calling functions opened by JTI:Getobjectsize: Gets the size of the memory that the specified object occupies.Followreferences: Gets all objects that can be accessed from the specified object.In other words, the Java code of the application layer can get the abo

You need to add the following third line to the InitInstance () in the app class: ccommandlineinfo cmdinfo; ParseCommandLine (cmdinfo); // prevent automatic creation of blank subforms // dispatches the command specified on the command line. Returns FALSE if // using/RegServer,/register,/unregserver, or/unregister to start the application. if (!

so-called literal. For example, int num=1,num is a variable box, and 1 is the literal, that is, the thing in the box.In the end, the program output the contents of these three variables, in the console printout of the common statement is System.out.println (), the parentheses inside is to output the content, here is used in the above variable. When you use variables, you need to be aware that they must be declared and initialized before they are used.The simple point of the declaration is the t

Makefile slightly moved, that is, the original beginning of the "Led_on.bin" to "all", eclipse default compilation target is "All", it can be successfully compiled, after compiling will produce led_on.bin,led_on_elf. The former is downloaded to Nandflash, which is used for debugging.can be compiled after the start of configuration debugging, and debugging U-boot The only difference is the name of the specified application, as shown in. The other Debugger commands are the same as those configured

For designing embeddedFor developers of Linux systems, there is a problem that must be taken into account, which is the memory space.We know that embeddedThe storage used by the Linux system is not a floppy disk,Zip disk,CD-ROM,DVD of these well-known large-capacity conventional memory, which is used for exampleRom, CompactFlash,M-systems'sDiskonchip,Sony'sMemoryStick,IBM'sMicrodrive such as small size, with the motherboard on theThe BIOS is similar in size and has very small memory capacity.

After a long time using a computer, we generally use a certain number of specific software. For example: Internet Explorer is not very easy to use yo (personal opinion), and friends to contact with Tencent QQ, MSN Messenger, download files with Flash get and so on. So do you think it's a lot of time to tap the software shortcuts in the Start menu or the Quick Launch bar to open the software? Yes, I agree! Actually, we don't have to be so troublesome. By clicking on the shortcut to open the appr
