Even more troubling, there are often cases where you cannot delete these remaining DLL files. The reason is that the DLL file is being invoked by a process that is running on the current system.

After reading this hint, many netizens try to reinstall the application according to the prompt method to resolve the failure, perhaps reinstall the application may be able to remove the failure, if the failure is still what to do? Then we continue to look down.
What is Mousesrv32.dll?
Reinstalling the application does not solve the problem, let's learn about this Mousesrv32.dll file. Mousesrv32.
Although everything that can be implemented using DLL can be implemented using COM, dll has many advantages and is easier to create. This article will discuss how to use MFC to create different types of DLL and how to use them.1. Different types of DLLYou can use MFC to generate two types of DLL: MFC extension
Back door! I believe this word will not be unfamiliar to you, it's harm otherwise, but as people's awareness of security gradually enhanced, coupled with anti-virus software, "strong support" so that the traditional backdoor can not hide themselves, any little bit of computer knowledge, all know "check port" "Look at the process" in order to find some " Clues. " So, the writer of the back door adjusted the idea in time, focus on the dynamic link library, that is, the back door into a
There are two kinds of libraries:One is that Lib contains the information (ingress) of the DLL file in which the function resides and the location of the function in the file, which is provided by the DLL that is loaded in the process space by the runtime, called the dynamic link library.One is that Lib contains the function code itself, which is added directly to the program at compile time, called static
The same problem is when I interview the director, the director asked me a question, these days have been busy, have not read a book, summed up this question today? Why does a process use a dynamic link library and another process can continue using it? At that time, the answer is very general, only half of the answer, and now here to summarize it!As we have said before, there are several ways to communicate between processes, but the dynamic link library We are talking about is also one of the
