When you select a file or folder in Explorer window, and choose ' properties ' From the menu, you get the Properties window that contains some essential information about the file: the size of file, created date, modified date, attributes, and so on . It's possible to display this properties window programmatically, by using the shellexecuteex API function. the function below accept 2 parameters, and displays the Properties window of the file: hwnd -The handle of the window that call

. The definition of a class takes up a certain amount of storage space, and the class definition method and class name are stored together. When a specific object is produced, the Face object language system allocates storage space for this object, which mainly stores the name and data member of the object; The static characteristics of an object are unique to each object, but the dynamic feature is public for all objects of a certain type. The biggest difference between an interface and a class

Visual Studio 2010 is Unicode by default, and projects that are compiled successfully in VC 6.0 often have type errors in VS2010. The common error is that you cannot convert from const char * to LPCWSTR, such as using CreateDC ("display", null,null,null), if you use CAST (LPCWSTR) "Display", though you can pass, But the encoding will go wrong. The possible way is to use text ("display") to convert, CreateDC (text ("Display"), null,null,null); Another

("str1"); Char str2[] = "str2"; WCHAR str3[] = L ("STR3"); The first line of code is equivalent to the third line of code when Unicode is defined, and none equals the second row.But the first two lines of code, whether or not Unicode is defined, generate an ANSI string, and the third line of code always generates a Unicode string.For the portability of the program, it is recommended to use the first presentation method.In some cases, however, if a character must be ANSI or

object;. For example, declaring an object of a clock class: Clockmyclock;. When you declare an object, you can access the public members of the object, which requires the use of "." operator, the general form of calling a public member function is the object name. Public member function name (parameter table), access public data member in the form of object name. Public data member. Of course, the general data is private, but it does not exclude the public type at times. For example, the member

Chinese is GB2312, which mistakenly considers the printf output UTF-8 string to be GB2312, causing garbled characters.3.2 Best SolutionIf there are no non-ASCII characters in the string constants, it is recommended that the source file use unsigned UTF-8 encoding to support the earlier compilers.If the string constants contain non-ASCII characters, it is recommended that the source file use a signed UTF-8 encoding, which will enable most compilers to correctly handle the source character set.Su

In the VC program How to end the system is running other processes (the process must have a window interface), in fact, very simple, as the following steps can be: 1. Obtain the handle of the process (obtained by using the FindWindow function); 2. Get process ID number (obtained by GetWindowThreadProcessId function); 3. Open the process, the first parameter in the OpenProcess function is set to Process_terminate, you can get the handle that handles th

VC We often use the shortcut keys, there are a variety of shortcut keys, including Menu,button. There is also a distinction between local and global, where local functions are effective when the current program has the focus (activated), and global, which is effective at all times, and test local priority over global, That is, if the shortcut key for the active window overlaps the shortcut key of the inactive window, the current active window priority

To start another application in the application, there are 3 functions to use, and I'll talk about them (I'll open the Zeecalls.exe application in the D:\Program files\zeecalls\ directory for example): 1, WinExec This function is the simplest, with only two parameters, and the prototype is as follows: UINT WinExec (LPCSTR lpCmdLine,//Address of commandUINT ucmdshow//window style for new application); Use the following methods: WinExec (_t ("D:\\Program files\\zeecalls\\zeecalls.exe"), sw_showmax

:: Is the "scope decomposition operator" in C + +. For example, declaring a Class A, Class A declares a member function VOIDF (), but does not give the definition of F in the declaration of the class, then the definition of f in the class is written as Voida::f (), which means that the F () function is a member function of Class A.:: There is generally a use, is directly used in the global function before, the expression is a global function.

For many programmers, SQLite is no stranger. SQLite is a major open source database for embedded, can be integrated in its own desktop program, can also replace access as a background database. SQLite supports most SQL92 standards, such as indexing, throttling, triggering, and viewing support, support for NULL, INTEGER, Real, TEXT, and BLOB data types, and supports transactions. Here are some simple uses of SQLite. Establish database c:\sqlite-3_6_11> Sqlite3.exe dbname.db When you
