A few days ago due to the need for programming. To do a static control with a border, so in the trace of other people do the basis of 3DBar, oneself made a C3dbar class, now dedicate it to everyone. Here's how to use C3dbar. The use of this class is simple, with a total of 7 public functions in 3DBbar. respectively: void SetBarColour(COLORREF cr); void DrawHorizontal(CDC* pDC, CRect BarRect); //画水平bar void DrawVertical(

There are many ways to draw a device context. For example, by creating a bit drawing brush, you can use it to fill an area to achieve image rendering. In addition, you can use the CDC class's bitmap function to output a bitmap to the device context.The BitBlt is used to copy bitmaps from the original device to the target device in the following syntax format:Boolbitblt (int x,int y,int nwidth,int nheight,cdc

First, the basic concept of mapping modeThe mapping mode is a Device Description table property that determines how the logical coordinate value is converted to the device coordinate value. The logical coordinate value that is passed to the CDC output function. The device coordinate value refers to the corresponding pixel point position in the window.Mm_text is the default mapping mode and can be called Cdc
This article gives a class called CMEMDC, which encapsulates the operation of drawing the off-screen buffer. Therefore, it is very easy to add CMEMDC to an existing application or ActiveX control to solve the flicker problem. How to modify an MFC application with CMEMDC add memdc.h to your project add #include "memdc.h" to the stdafx.h to add the Windows message handler function for the WM_ERASEBKGND message and then make the following changes to the message handler function: [CPP] view plain co

The so-called ing method is simply the coordinate arrangement method. The default ing method isMM_TEXT means that the X coordinates increase to the right, and the Y coordinates increase downward. () at the top left of the screen, each point in DC is a pixel on the screen. You may think this method is the best way to understand, but the relationship between a point and a pixel is normal on the screen, but it will be abnormal on the printer. Because our plot is in dot units and the resolution of t
1. How can I obtain the instance handle of an application? The instance handle of the application is stored in cwinappim_hinstance. Afxgetinstancdhandle to get the handle. Example: handle hinstance = AfxGetInstanceHandle (); 2. How to get the pointer to the main window of the application through code? The pointer of the main window is saved in cwinthread: m_pmainwnd, And the afxgetmainwnd implementation is called. Afxgetmainwnd ()-> showwindow (sw_showmaxmized); // maximize the program. 3. How

The first method (it should be the best way, you can modify the color of a single control, maybe other types of controls can also be used ): First, we add the onctlcolor message ing function in the dialog box. For function functions, function prototypes, and parameter explanations, see the msdn description ~ Quote: Cwnd: onctlcolor See alsoCwnd overview | class members | hierarchy chart | CDC: setbkcolorThe framework callthis member function when a
There are many ways to draw a device context. For example, you can create a bitmap image brush and use it to fill an area to draw an image. In addition, you can use the bitmap function of the CDC class to output the bitmap to the device context. Bitblt is used to copy bitmap from the original device to the target device. The syntax format is as follows: Boolbitblt (int x, int y, int nwidth, int nheight, CDC
m_pmainwnd = DLG; 5 // call before domodal (), set the dialog box to blue background, red text 6 setdialogbkcolor (RGB (255 ), RGB (255, 0, 0); 7 int nresponse = DLG. domodal (); 8 ...} Compile and run. The background color and text color of the dialog box have changed. It is worth noting that setdialogbkcolor must be called before domodal () is called, and this method will change the color of all the dialogs in the application and cannot target a specified dialog box.

message. The following example describes how to create a red background dialog.First, add the one-person member variable cbursh to the dialog base class:Class cmyformview: Public cformview{...PRIVATE:Cbrush M _ brush; // background brush...};Second, initialize the brush to the desired background color in the class constructor.Cmyformview: cmyformview (){// Initialize background brush.M_brush. createsolidbrush (RGB (0, 0,255 ))}Finally, use classwizard to process the wm_ctlcolor message and retu
The GDI bitmap is just another GDI object, such as a pen or font. You must first create a bitmap and then select it into the device environment. After modifying an object, you must unselect it and delete it. Even so, there are still some problems because the "bitmap" of the display is actually the display surface image, and the "bitmap" of the printer device is the print page itself. Therefore, bitmap cannot be selected into the display device environment or printer device environment. You must
color for the originalThe drawn image is cleared, and the new image is superimposed.Some people may say that flashing is caused by the drawing speed being too slow or the graphics displayed are too complex,In fact, this is not true. The influence of the display speed of the drawing on the flicker is not fundamental.For example, in ondraw (CDC * PDC), write as follows:PDC-> moveTo (0, 0 );PDC-> lineto (100,100 );This drawing process should be very sim
