In the previous article, I briefly explained the differences between NTFS file sharing and FAT32 file sharing in Windows XP. In the second half, I will not talk nonsense, directly paste the key code that sets the read and write permissions for file sharing. First, set the folder as the shared code: Code highlighting produced by Actipro CodeHighlighter (freeware)http://www.CodeHighlighter.com/-->// Set a folder for net share NET_API_STATUS AddNetShare

Windows API one-day training (73) getversionex Function Windows development is still very fast, from Win95 to Win98, to Win2000 and XP systems. Each system has different functions. to distinguish different systems in a program, you need to obtain the system version information. For example, there is a firewall in XP, but not in other previous systems. However, s

Windows has two mainstreamProgramInstallation Technology: Compile the setup.exe file, read the INF configuration file during program installation, release the files stored in the cab file to the specified location, and set the environment. The second method is to use the Windows Installer Service to create an MSI file. The Windows Service reads the configuration

Ii. Heap Management The memory allocated by the user's memory allocation function is in the heap. Therefore, using the heap management function to allocate and release the memory is the most direct method. In Windows, each process has its own heap, and the number of heap processes varies.In Windows, the so-called heap is not a memory block, but an object used for memory management and a memory

information stored in the database includes the services installed by the system, each service includes how to start each service, the security attributes of each service, and control interfaces. The functions provided by SCM are used to design service programs, service configuration programs, and service control programs. 3. A service program is an executable program required to run the service. SCM starts and stops the service by running and terminating the service program. 4. S

need to wait for you to unlock first.The workaround is to set the shared lock on the read of the file. Multiple threads can read files at the same time. Do not clog each other. Then set the exclusive lock when you want to write to the file. Add an exclusive lock so that other threads cannot read or write at this time.Windows provides a shared/exclusive lock called Slim to resolve the issue. But then. Slim is only supported in Vista and Windows Server

Windows API one-day training (63) regopenkeyex and regcreatekeyex Functions Because the computer is often shut down, or applications are often closed, but some parameters need to be saved frequently. For example, when you open a program and set the window size, you want to set the window size to the size of the previous window. In this way, you need to save the size of the window. What about the window siz

Qt sends messages to Win32 very easily, but it is very complicated to obtain Windows messages. Finally, I thought of a method that is not perfect, but it is also the only way that I can achieve it now, the basic principle is to use VC to compile an mfc dll, which creates a transparent form and uses this DLL to obtain Win32 API messages. The source code has been tested in vs2010 vs6.0 QT 4.7 Below is an i
