Add Method. You can continue to add multiple methods ... 5, the implementation method (in fact, the component is only to make the declaration of methods, the customer calls to implement these methods). When implemented, select the component/class, press the right button, and select Implement Connection in the pop-up menu .... will produce cproxy_xxxevent classes, which have the implementation of the fire function, are automatically generated. 6. Complete the other interface functions of the com

(dispparams, 0, sizeof dispparams); Dispparams.cargs = ArraySize; Dispparams.rgvarg = new Variant[dispparams.cargs]; for (int i = 0; i When actually used, it is possible to first access (Navigate) a page. Then, in VC inside the page for some JS call, and retrieve the results. It is possible that this JS call function is not in this page. It is generally possible to call an eval (some JS statements) in the form of a function that is not in

We often encounter the need to build multiple threads so that we can execute multiple events at the same time. This is our VC development in a foundation, although I have used many times, but also will often forget. This time write down, as a note, for everyone to learn to provide convenience.In VC, nothing more than creating threads and writing thread functionsOne, the conventional method: pure use platfor

This article mainly combines with MSDN on several official documents about WinSocket, creates a simple VC + + Socket Sample program, demonstrates a basic CS model. Reference links are as follows: Msdn:windows Socket 2 Getting Started with WinSocket Other Blog: VC network programming C + + Socket First, c/s--client and server In network programming, the most common is the C/S model, which has one (or more)

This article describes the VC + + implementation view content saved as a picture of the method. Share to everyone for your reference, specific as follows: In a single document application, we often need to save content in view as a picture file in a variety of formats for printing. At first glance, may not know where to start, in fact, the main is to use the bitmap save method, such as: HDC HMEMDC =:: CreateCompatibleDC (HDC); Hbitmap hbmp =:

This article is an example of how VC determines whether a process has admin permission. Yes, returns True, otherwise false. Share to everyone for your reference. The implementation methods are as follows: Copy Code code as follows: Static BOOL isadmin (void) { HANDLE Haccesstoken; BYTE infobuffer[1024]; Ptoken_groups ptggroups; DWORD dwinfobuffersize; Psid psidadministrators; Sid_identifier_authority siantauthority = security_nt_au

This article describes the VC through the system snapshot to achieve process management methods, share for everyone to reference. The implementation methods are as follows: First, the introduction Each application instance will produce a process under the current system after running, and most applications will have a visual interface, and the user can close the program with the Close button on the title bar. But there are a number of programs runni

This article illustrates the difference between SendMessage and PostMessage in VC. Share to everyone for your reference. The specific analysis is as follows: 1, first of all, the difference between the meaning of the return value , we first look at the MSDN statement: Copy Code code as follows: LRESULT SendMessage (HWND hwnd, UINT MSG, WPARAM WPARAM, LPARAM LPARAM); Copy Code code as follows: BOOL PostMessage (

This paper collects and summarizes the VC in the dialog box commonly used in some of the skills for VC development due to a certain reference value. 1. How to modify the background color of the dialog box: In the OnPaint () function of the dialog box, add the following statement: CRect rect; GetClientRect (rect); Calculates the size of the dialog box DC. Fillsolidrect (rect,rgb (192,248,202));

In VC + + program design, combobox control is more common form element control, and for beginners, master the various usages of ComboBox is particularly important, this article will summarize some practical ComboBox control usage, for everyone's reference. Add/Remove combo box content: 1. It is generally added in the Data tab of the ComboBox control properties, one line representing a row in the ComboBox Drop-down list, and CTRL + ENTER for the newl

This article describes the VC + + operation of the text file method, the implementation of TXT file at the specified location inserted content. For VC + + enthusiasts have a certain learning reference value. The main functional code is as follows: void Cgotofiledlg::onpaint () {if (Isiconic ()) {CPAINTDC DC (this); SendMessage (Wm_iconerasebkgnd, (WPARAM) DC. GETSAFEHDC (), 0); int cxicon = GetSyste

This article illustrates the two ways to remove classes in VC. Share to everyone for your reference. The specific methods are as follows: Method One: You should first delete the. h and. cpp files in Windows, then open the project, Ctrl-w Open the Class Wizard, select the dialog class, then hint that you can't find it, select Remove, and then select the two files in the File View list. Press DELETE to delete it so that it is completely otherwise. clw

This article describes the VC external symbol error _MAIN,_WINMAIN@16,__BEGINTHREADEX solution. Share to everyone for your reference. Specifically as follows: When you create an MFC project, you do not use the MFC AppWizard Wizard, and if you do not set the project parameters, many connection errors, such as Error LNK2001 errors, are generated at compile time. Typical error tips are: LIBCMTD.lib (crt0.obj): Error lnk2001:unresolved external symbol_

This article describes the VC to obtain the computer name and IP address method. Share to everyone for your reference. The implementation methods are as follows: #include I hope this article on the VC program for everyone to help.

The following C + + refers to managed C + +, if the use of Win32 C + + and. NET ratio is meaningless, there is no technical content.
