background to null, the duplicate drawing will not flash. Of course, this will make the display of the window messy, because there is no background color for the original graph during re-painting.And overlay the new image. Some people may say that the blinking is caused by the drawing speed being too slow or the display graphics being too complex. In fact, this is not true. The display speed of the drawing has no effect on the flashing speed.Is fundamental. For example, in ondraw (

In experiments and production, we often need to monitor the monitored objects in real time, for example, to collect real-time data for environmental factors such as the site temperature, and then transmit the data to the master control computer, it is displayed in a dynamic curve to facilitate people's understanding and control of the site.2. There are four ways to draw dynamic curves using Visual C ++. (1) Use deactivating. (2) Use redrawing. Based on different principles, repainting is divided

curve through parameters to scale the font freely. 8.2.2 class related to GDI in MFC To support GDI plotting, MFC provides two important classes: the device context class, which is used to set drawing properties and Drawing Graphics. The drawing object class encapsulates various GDI drawing objects, includes paint brush, brush, Font, bitmap, color palette, and area. Device context The device context class includes the CDC and Its Derived classes ccli

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
