Use the windbg debugger to modify Starcraft and other games.

No more game modifiers. I used Kingsoft ranger at first, but not all games support it. You have successfully used windbg to modify the local machine and local network, and modified the money in local network mode. In the IOT connection mode, the client maintains a balance between data packets and the server, and the server records various client data. Therefore, it is useless to change the bullet. Use command cryptography. It can also be modif

Windbg executes the command cyclically.

In windbg, there are two types of cyclic commands: 1. Z command You can use the Z command to execute one or more commands cyclically. The format of the Z command is Z ( The following is a simple example: | 0: 001> r ECx = 3 | 0: 001> r ECx = ECx-1; r ECx; Z (ECx) Output: Ecx= 00000002 Redo [1] r ECx = ECx-1; r ECx; Z (ECx) Ecx= 00000001 Redo [2] r ECx = ECx-1; r ECx; Z (ECx) Ecx= 00000000 The above redo is a circular execution prompt.

CLR Exploration Series: windbg + SOS analysis reveals the domain world-cnblog

In the world of CLR, there are a series of amazing technologies and architectures. Among them, CLR allocates memory for the application in the memory, executes the model, and interacts with each other among other technologies, so every technical staff dedicated to the DOTNET platform deserves further research.During the development process, if programmers load the Assembly (assemblies load), reflection (reflection), host (hosting), and application domain (appdomain ), if these four technologies

This pointer trap of windbg

This pointer trap of windbg When you enter the class member function, this pointer does not immediately point to the object address. When you use this to set a memory breakpoint, this is a huge trap. The following class constructor is used as an example to analyze the assembly code in debug. CPP source code is as follows: Class node {public: node (); int data ;}; node: node () {int A = 10; A = (INT) This ;} void main () {node N; N. data = 100 ;

Analyze deadlocks using windbg

In WinDBG, use the. shell Command to search for strings.

One of the most useful commands for me to use WinDGB is the. shell Command. Debugging Tools For Windows Help file: The. shell Command can load a shell process and redirect its output to the debugger, or redirect it to a specified file. So why do I think loading a shell process will be helpful for daily work? The simplest and most common function for loading shell processes is to search for strings. You may wonder why Ctrl + F is not used in debugger to search for strings? This will s

Look at string from the perspective of WinDbg

program. As a result, instances of strings with specific values have only one instance of the system (APP Domain).The string declared directly inside the code is maintained within a object[] by the CLR runtime.0 o'clock the generated string or the stitched string is not maintained in this mainstream array.The life span of the residing array is as long as the app domain it resides in. So the GC does not affect the string that resides in the array that is referenced by the GC. The following

WinDbg Command Learning 2

One,WinDbg view Memory command :When we analyze a problem in the debugger, we often need to look at the contents of different memory blocks to analyze the cause, and then verify that the assumptions made are correct. Because the state of each object is stored in memory, the contents of the memory are equivalent to the state of the object.The most common format for the D command is to display the data stored in an address based on the specified type in

In addition to being able to act as a list of threads command, it can also be used to traverse threads and execute specified commands. Simply use the wildcard character "*". Such as: ~*k Displays all thread stack information (this command means that the k instruction is executed on all threads)

(Here the lock also refers to CriticalSection)?
