1. DefinitionCDC * PDC; HDC HDC;2. ExplanationHDC is a data type for Windows and is a device description handle.The CDC is a class in MFC that encapsulates almost all of the operations on HDC.The variables defined by HDC point to a piece of memory, which is used to describe the related contents of a device, so it can also be assumed that the HDC defines a pointer;The CDC class defines an object that has a

This article continues with my notes. The previous article introduced the persistence function of the image output by the CDC. It only introduced one method (the most common method for saving and redrawing drawing data ), this introduces the second method, This method uses metadata files to save the images you have drawn. The idea is simple: 　　 Metadata is used to maintain user-drawn graphics. Ideas: Each time the metadata file DC is used, the use

To continue with the previous two topics, the third way to enable the CDC to maintain its output graphics is to use compatible DC. 　　 Ideas First, use the current drawing DC to create a compatible DC. Compatible with DC is equivalent to a reference to the DC associated with it. It is like a canvas where users draw images. When the screen weight is painted, copy the canvas directly to the current DC to maintain the image. Speaking of a canvas, DC

DPtoLP ( point );// Allocate a space in the heap to save the redrawing data.CGraph * g = new CGraph (m_nDrawType, m_ptOrigin, point); // must use a point to CGraph// M_ptArray is a member variable of the CPtrArray type.M_ptrArray.Add (g );CScrollView: OnLButtonUp (nFlags, point );} The last step is to re-draw these images when redrawing the window.

CDC,CPAINTDC,CCLIENTDC,CWINDOWDC differences————————————————————————1, first, the DC to explain:Windows applications draw graphics on the "canvas" of the logical meaning of the DC representation by creating a device description table for the specified device (screen, printer, etc.). A DC is a data structure that contains device information that contains the various state information required by a physical device. The WIN32 program needs to get the DC

For a general-purpose device environment, the GETDC function initializes it with the default properties each time it acquires a device environment.The classes and private device environments that the function obtains are consistent with th

Create a project with a single document structure HDC: First, add windows message handler in the cyourclassview class. One is lbuttondown and the other is lbuttonup. Add the member variable m_ptorigin to record the initial vertex position. Initialize the m_ptorigin variable in the view struct: Cyourclassview: cyourclassview () { // Todo: Add construction code here M_ptorigin = 0; } Add the code to the lbuttondown function: Void cyourclassview: onlbuttondown (uint nflags, cpoint point) { // Todo:

I was worried for a moment, and thankfully, the news soon disappeared and then loaded the historical data.Testing is not a right or wrong judgmentWe discussed some aspects of mobile testing, but the premise is that problems can be found with problems.
