If I don't talk first, I'll take a look at some code snippets1 Using HWNDFind window:HWND h_wnd = ::FindWindow(_T("MainForm"), NULL);To create a window:HWND hwnd = WindowEx::Create(NULL, L"", WS_POPUP, WS_EX_TOOLWINDOW);2 Using handleSingleton run:BOOL Singletonrun (const wchar_t*application) {assert (application);if(Application== NULL)return false;HANDLEHmutex= :: Createmutexw(NULL,TRUE, application);if(Hmutex== NULL)return false;if(:: GetLastError()==Error_already_exists) {:: CloseHandle(Hmute

1, in the "C + + meditation" proxy class, the use of proxy classes, there are problems:A, agent replication, each time you create a copy, the cost is likely to be largeb, some objects can not easily create a copy, such as file2, how to solve this problem?Encapsulates a dynamic resource with a reference-count handle, a handle that contains pointers, and multiple handles can point to the same object. When cop

how to ensure this, it is a programmer, not an IOCP problem. the structure to which LPWSAOVERLAPPED is to be released can only be performed after I/O operations are returned from the completion of the port queue. that is, only after GetQueuedCompletionStatus () is returned. if the same WSAOVERLAPPED structure is used in multiple I/O requests, you can set a reference count. Each time you return a count minus one from GetQueuedCompletionStatus, it can be released at zero time (it is best to avoid

Principle and Design of the C ++ handle classThe processing class is used to make up for the slicing effect that occurs when the derived class object is assigned to the Base Class Object. For example, the following program: multimap That is to say, when the object of the derived class is assigned to the Base class, the slice benefit will occur, and the non-base class part of the derived class will be cut off, which will lose its meaning. To solve this

subwindow is saved to m_nage by integer type, or the value of m_nage is transmitted to the update display in the idc_age window. Ddv_minmaxint indicates that the value of m_nage should be between 1 and 100. The preceding ddx_xxx data exchange function can exchange data in two directions. How do they know the data transmission direction? This is determined by the cdataexchange object referred to by the first PDX parameter of the ddx_xxxx function (that is, the dodataexchange parameter PDX,

MFC helps us talk to Windows. MFC is a service company. MFC is equivalent to some tertiary industries, such as restaurants, such as enterprise ISO9000 certification consulting companies, such as business license agency.All the reasons are that these things are complicated, so we introduced MFC to help us.In fact, it is the same as that of the certification consulting company that helped us prepare reports and then contacted the certification authority. MFC communicates with the god of windows th

External third-party program initiated through process in the original C # Mainwindowhandle handle is 0a few days ago, I encountered a WinForm program in C # that started a third-party jar program and modified the jar to run the form's title. The general requirements are described above, the following is the original ideas and implementation of the code. STEP1//Based on the path to the jar file, start the jarProcess p = process.start (Jarfilepath);STE

Learn to deal with anomaliesC # programmers can use a try block to partition code that might be affected by an exception. The associated catch block is used to handle any resulting exception. A finally block that contains code that runs regardless of try whether an exception is thrown in the block (for example, freeing try resources allocated in a block). A try block requires one or more associated catch blocks or a finally block, or both.A statement

Close a form today and report an error like "You cannot call invoke or BeginInvoke on a control until the window handle is created." "This doesn't have to be a lot of thinking, it must be that place is not released."Since we have encountered this problem, we should not say the problem itself, but say something else.WinForm most common is the DataGridView this control, regardless of rewriting or how, a lot of data operation is to use DataGridView to sh

The previous section, "Containers and inheritance," http://blog.csdn.net/thefutureisour/article/details/7744790 mentioned:For a container, if defined as a base class type, you cannot access the new members of the derived class through the container, and it is critical that the base class object can access the non-meaningful derived class members if it is defined as a derived class type and is not generally used to host objects of the base class, even if it is forcibly hosted with type conversion

Authors who read this article recommend that you understand Java reflection and dynamic proxies first. JAVA7 introduces a new API for indirect calling methods, the most critical of which is the Java.lang.invoke package, the method handle. We can be seen as an upgraded version of Java reflection, but it does not reflect that sometimes it looks long and heavy rough. The method handle first involves two impor

Windows are a very important element in Windows applications. A Windows application has at least one main window. A window is an interface that Windows applications and users interact with.Windows typically contain title bars, menu bars, system menus, minimized boxes, maximized boxes, adjustable borders, and scroll bars.Windows are divided into customer and non-client areas. Applications typically display text or draw graphics in the customer area. Title bar, menu bar, System menu, minimum maxim

creating a form handleWhen the window is created, the window does not create a handle, only Application.Run (form) or form. Show () is followed by a handle, that is, the window only displays or starts the message loop before the handle! If the form is created, the form is called in the main thread. Handler, if the handle
