Change the icon of a dynamic thread: cj_ict
Download this article The sample code has seen a "How to display the Dynamic Icon" article in the title bar, the author is a Chongqing Construction Group Tang Xingbin. I feel that it is troublesome with setTimer and takes up resources. The hand itching will change it to threads and package threads in the class. Use simple, no need to set SETIMER to call in the ONTIMER function. Just call directly
M_animicon.setimagelist (idb_bitmap_anim, 6, rgb (0,0,0));
m_animicon.draw (this);
I.e. Other parts of the program is to use Tang Xingbin, I just changed the part of the ONTIMER implementation.
