Some of the tools that I used to write in college have recently been sorted out and turned out to be of some use to everyone. Download the address on each of the detailed introduction page: Truthtracerutilities-syswatcher process/Module

(recommended during debugging), or copy to the VC project executable location (copy when installing to another machine).The above is from the network, not original, pro-test available. To avoid cloud loss, special copy.The following is your own configurationComplete ICPTESTUSINGVTK configuration in VC project.

, more DLL files will be generated. These DLL files must be copied to the Windows/system directory. If you use static library programming, that is, off, the application can run independently and the size is relatively large. If you use dynamic library programming, that is, on, the application must find a dynamic library to run. After all the items are dimmed, you can click Generate. when the project is finished, generating done is displayed, and cmake is disabled. 5. Use VC ++ 2008 to open the

Article Title: how to use the GNU text utility. Linux is a technology channel of the IT lab in China. Includes basic categories such as desktop applications, Linux system management, kernel research, embedded systems, and open source. This tutorial shows how to use the GNU text Utility Set to process log files, documents, structured text databases, and other textual data or content sources. The utilities in this collection have been improved by UNIX/L

The following articles mainly describe the Distributed Management of DB2 9. In this column, we will explain the actual operation steps for performing automatic maintenance, it also describes how to use the utility to throttle if maintenance operations need to be performed when the DB2 database is processing the workload. Preface The adaptive utility of DB2 9's throttling system enables maintenance during busy hours. If you want to keep your car in good state, you must perform regular maintenan

, you must first compile, link, and load the program. Although such a concept is familiar to everyone, during the development of the operating system, it has undergone many major changes. In short, it can be divided into the following three stages:1. Static link and Static LoadingThis method was first adopted. It features simplicity and does not require any additional support from the operating system. Programming languages like C have already supported separate compilation since very early on.
