Refresh the Windows Desktop (Views: 704)

Problem/Question/Abstract: How can I refresh the Windows desktop after I have set a new background image in the registry? Answer: Solve 1: I want to post this article because I sure that this question can ask a lot of developers but to find an answer is not easy task. So if you need refresh a desktop in run-time, you can execute a next procedure: uses ShlObj; {...} SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, NULL, NULL); This code will refresh a desktop image and re-read the icons for files with registered extentions. PS: you can do a same if you press a right mouse button on desktop and select Update item. Solve 2: procedure TForm1.Button1Click(Sender: TObject); begin SendMessage(FindWindow('Progman', 'Program Manager'), WM_COMMAND, 106597, 0); end; This has the same effect as pressing F5 in Explorer. |
