played a role. This reuse is referred to as "black box multiplexing".There are two types of executables in the Windows operating system, with the following suffix. exe and. dll. The difference is that the. exe file can be run independently of the memory, and the. dll file cannot, it can only be called by other processes. However, in any format, they are binary files. The above-mentioned "binary level" code
"@" and then the function name, the symbol "@" and the number of bytes of the parameter are followed. For example, the modifier of the int func (int A, double B) function is @ func @ 12. For the "C ++" function, it is different.In the future, compilers may use different registers to store parameters.
Functions declared in DLL using _ declspec (dllexport:_ Declspec (dllexport) only indicates that this function is a
Reduce the number of generated dll and the number of generated dll
Before the opening, I want to despise myself. I don't need to write this thing at all. I already have something to implement. As my team lead said, there are too few open-source projects. In fact, this thing can be completely solved by ILMerge.
Then let's talk about the preface. After developing things for a long time, we will always accumul
Before writing, I would like to briefly introduce the differences between hosting and non-hosting C ++. In fact, I have not thoroughly understood the features of hosting C ++, the biggest feature is that the system can debug and recycle relevant code resources. Like C #, the programming style is similar to C ++. Therefore, this determines that C # can be perfectly integrated with hosted C ++. It should be said that the dll generated by hosting C ++ is
The principle of this method is to write a DLL with the same interface function as the DLL called by the original process, and then replace the original DLL with our DLL. During the replacement process, we will write functions of interest to replace the original functions, while functions of the original
. Net is a language based on virtual machines. It directly generates the msil intermediate language, and then the. NET compiler JIT interprets the image as the local code and delivers the CPU for execution. The intermediate language is easily decompiled, so we will study how to effectively protect DLL files.
My general method is:Strong signature + obfuscation + encryption.
Strong SignatureA strongly-named Assembly ensures that your assembly is unique
In plug-in development of Microsoft Dynamics CRM 4.0, third-party DLL is often referenced. If it is deployed on a disk, it will not have a great impact. If it is deployed on a database, the plug-in cannot run because it references a third-party DLL. In my opinion, the plug-in deployment tool only serializes the plug-in DLL to the database, but the third-party
After one night of hard work, I decided to write down some of my experiences to avoid repeated work in the future.
C # compared with C/C ++, the advantage of the former lies in the UI, and the advantage of the latter lies in the algorithm. Although the pointer in C ++ is disgusting, it is quite convenient to use it properly, the most important issue is that many popular development tool libraries on the market almost do not support C ++, but it is rare to fully support C #. As the CPU has grown
DLL file is a dynamic database file, is an executable file, in general, he is to allow the program to perform special tasks required by the Code and resources, the general DLL file is followed by the DLL extension file, but some may also be exe and other extensions. They provide code, data, or functions to programs running under the Windows operating system. Prog
Introduction: AjaxPro. dll and AjaxPro.2.dll are a set of components used to apply Ajax technology. They are all called Ajax. NETProfessional. The official website address is www.ajaxpro.info. The website has a Demo that uses this technology. Ajaxpro. dll is a component used for. net1.1, and ajaxpro.2.dll is used for.
VS ~ Single-step DLL debugging, vs single-step dll
Sometimes, after we download the DLL library from a third party, it is still very troublesome to use VS for debugging. Now I will summarize the DLL debugging method in the development process, I hope it will help you in development.

To search for the php4ts. dll (php5ts. dll) method, php4ts. dll (php5ts. dll) is required for CGI, CLI executable files, and web server modules ). Make sure that the file can be found in the PHP installation path. The search sequence for this DLL is: nbs search php4ts.
It's actually the old post of a previous blog. If you haven't written a blog for too long, paste it.
Since max9, maxscript can directly call. Net DLL files and create classes to use the methods. And. Net can call the DLL file written in C ++. Therefore, you can use C # to encapsulate the C ++ code and call it in Max. The following is an example.
--------------- Below is

During the underlying Encoding Process of. net, multiple dll may be generated for function independence, which is inconvenient to reference. In this regard, Microsoft provides an ilmerge tool, the original dostool, which can merge multiple DLL files into one. After the download is complete, install it and run the doscommand. The usage is as follows: D: \ Program

1) generate DLL
Create two files: XXX. H, XXX. cpp
The content of XXX. H is as follows:
# Ifdef build_xxx_dll# Define export _ declspec (dllexport)# Else# Define export _ declspec (dllimport)# Endif
Extern "C "{Export void example (void );......}
The content of XXX. cpp is as follows:
# Define build_xxx_dll# Include "XXX. H"
Void example (void){}......
Then compile from the DOS Console
