CWin. App Class Microsoft Docs. The base class from which you derive a Windows application object. Syntaxclass CWin. App public CWin. Thread. Members. Public Constructors. Public Methods. Protected Methods. Public Data Members. Protected Data Members An application object provides member functions for initializing your application and each instance of it and for running the application. Each application that uses the Microsoft Foundation classes can only contain one object derived from CWin. App. This object is constructed when other C global objects are constructed and is already available when Windows calls the Win. Main function, which is supplied by the Microsoft Foundation Class Library. Declare your derived CWin. App object at the global level. When you derive an application class from CWin. App, override the Init. Instance member function to create your applications main window object. In addition to the CWin. App member functions, the Microsoft Foundation Class Library provides the following global functions to access your CWin. App object and other global information Afx. Get. App Obtains a pointer to the CWin. App object. Afx. Get. Instance. Handle Obtains a handle to the current application instance. Afx. Get. Resource. Handle Obtains a handle to the applications resources. Afx. Get. App. Name Obtains a pointer to a string containing the applications name. Alternately, if you have a pointer to the CWin. App object, use mpsz. Exe. Name to get the applications name. See CWin. App The Application Class for more on the CWin.

SmartPCFixer is a fully featured and easytouse system optimization suite. With it, you can clean windows registry, remove cache files, fix errors, defrag disk. There are two types of windows or controls you will deal with in your applications. The type is defined by the relationship a window has with regards to other windows. There was a recent newsgroup posting about asynchronous sockets in separate threads. I pointed out many failures in the code, thinking it had been written by the. A CWnd object is distinct from a Windows window, but the two are tightly linked. A CWnd object is created or destroyed by the CWnd constructor and destructor. You will want to do the following before the static text control is shown on the parent window. Get a handle to the window CWnd pwnd GetDlgItemIDCLABEL.

I have a situation where Im starting a process in my code in order to set up an IPC channel. The process Im starting is an MFC application with no CLR support. Parametersp. Template.

You should call the Load. Std. Profile. Settings member function to load the current MRU file list before you use this member function. The framework calls this member function when it opens a file or executes the Save As command to save a file with a new name. Example This adds the pathname c temptest. MRU list in the File menu.

CallbackLPVOID lpv. Param. Parameters in lpv. Param. Reserved for future use. Return Value 0 if this method is successful nonzero if an error occurs. If your application supports the restart manager, the framework calls this function when your application unexpectedly exits. The default implementation of Application. Recovery. Callback uses the CData. Recovery. Handler to save the list of currently open documents to the registry. This method does not autosave any files. To customize the behavior, override this function in a derived CWin. App Class or pass your own application recovery method as a parameter to CWin. App Register. With. Restart. Manager. CWin. App Close. All. Documents Call this member function to close all open documents before exiting. Close. All. DocumentsBOOL b. End. Session. Parametersb. End. Session. Specifies whether or not the Windows session is being ended. It is TRUE if the session is being ended otherwise FALSE. Call Hide. Application before calling Close. All. Documents. CWin. App Create. Printer. DC Call this member function to create a printer device context DC from the selected printer. BOOL Create. Printer. DCCDC dc. Parametersdc. A reference to a printer device context. Return Value Nonzero if the printer device context is created successfully otherwise 0. Create. Printer. DC initializes the device context that you pass in by reference, so you can use it to print. If the function is successful, when you have finished printing, you must destroy the device context. You can let the destructor of the CDC object do it, or you can do it explicitly by calling CDC Delete. DC. CWin. App CWin. App Constructs a CWin. App object and passes lpsz. App. Name to be stored as the application name. CWin. AppLPCTSTR lpsz. App. Name NULL. Parameterslpsz. App. Name. A null terminated string that contains the application name that Windows uses. If this argument is not supplied or is NULL, CWin. App uses the resource string AFXIDSAPPTITLE or the filename of the executable file. You should construct one global object of your CWin. App derived class. You can have only one CWin. App object in your application. The constructor stores a pointer to the CWin. App object so that Win. Main can call the objects member functions to initialize and run the application. CWin. App Del. Reg. Tree Deletes a specific registry key and all its subkeys. LONG Del. Reg. Tree. HKEY h. Parent.

Name. The name of the registry key to be deleted. TMPointer to CAtl. Transaction. Manager object. Return Value If the function succeeds, the return value is ERRORSUCCESS. If the function fails, the return value is a nonzero error code defined in Winerror. Call this function to delete the specified key and its subkeys. CWin. App Do. Message.

Parameterslpsz. Prompt. Address of text in the message box. Type. The message box style. IDPrompt. An index to a Help context string. Return Value Returns the same values as Afx. Message. Box. Do not call this member function to open a message box use Afx. Message. Box instead. Override this member function to customize your application wide processing of Afx. Message. Box calls. CWin.
