For your problem, you need to first create a Font object with CreateFont, and then call the control's setfont.Example:1, change the ID of the static style, such as: Idc_static12. Add an edit control to create an associated control M_editcontrol.3. Ad

The Declaration sequence and structure sequence of the member variables in MFC, and the declaration of the mfc member variables I used my blog for the first time and wrote the first article casually. Let's write a question that I encountered today. In the MFC Dialog Box program of VS2008, the Declaration Order of window member variables is the opposite to that

Summary of MFC view switch and mfc View Switching between views Multi-view switching of a single document is an old and difficult problem I encountered in learning MFC. Today, I finally cracked it one by one. In my opinion, view switching is divided into three levels. The first is to switch the View class without splitting the pane, and the second is to implement

MFC toolbar hide and display, and mfc toolbar hide Recently I was studying MFC and watched sun Xin's VC ++ video. I feel pretty good. When I saw the ninth lesson, I made a small function when talking about the toolbar: hiding and displaying the toolbar, but a bug is that a floating toolbar is hidden and then displayed, it will become a stopped status. Here, I hav

MFC text programming overview, mfc text Overview This section describes the basic knowledge of text programming.We use the following code to familiarize ourselves with the basic functions of text programming and their respective functions. We use CClientDC to create a device description context object dc, and then define a TEXTMETRIC object. The TEXTMETRIC struct object is used to indicate the font informa

When vs2008 is used, there is one of the following MFC settings in the project properties: 1. use the standard Windows library 2. use MFC in shared DLL 3. use the first type of MFC in a static library as the name suggests. The second type means that the content of some mfc dll files is not included in the EXE files dur

beginpaint in the WM_PAINT processing function? The program will achieve a staggering CPU usage as it enters a dead loop, and you will find that the program is always processing one WM_PAINT message after another. This is because, in general, when an app receives a WM_PAINT message, the window's update region is non-empty (if it's empty, you don't need to send a WM_PAINT message), and BeginPaint's role is to empty the updateregion. This way, if you do not call BeginPaint, the window's update re

Understand basic mfc controls and mfc controls In almost every windows program, buttons, check boxes, text boxes, and drop-down lists are all controls. In addition, many common controls have been built into the operating system. in Visual C ++, these commonly used controls have been simplified and can be placed in a dialog box using the "Drag and Drop" window design method. There are six controls that appea

The string for verifying the rationality of the MFC Setting Dialog Box and the rationality of the mfc After DDX is associated with a control variable, rationality verification is often not what we need. For example, "enter an integer" and "please enter a integer ". DDX is actually an encapsulation call of GetDlgItem. For this reason, you can enter the rc file corresponding to the project, first comment ou

Windows Control window Windows (Windows95 or above) provides a series of common control windows, including a toolbar (ToolBar), a status bar (StatusBar), a ToolTip window (TOOLTIP). Windows registers the window class for a control window when a DLL is loaded. For example, the window class for the toolbar is ToolbarWindow32, the window class of the status bar is Msctls_statusbar32, and the window class of the ToolTip window is tooltips_class32. To ensure that the DLL is loaded, the function Ini
