如何刷新系统让注册表的设置立即生效？

Question

我用程序在注册表中修改了鼠标的指针，但是要重新进入系统才可以生效，用什么办法可以让它立即生效的呢？给个代码，谢谢了：）

Answer 1

在你的程序修改注册表的代码段的后面加上一句:
SystemParametersInfo(SPI_SETCURSORS,0,NULL,SPIF_SENDCHANGE);      就可以了

Answer 2

注意: 要在RegCloseKey(hkey);  后面

Answer 3

不行啊？
我设置的是：
Windows Registry Editor Version 5.00[HKEY_CURRENT_USER\Control Panel\Cursors]
@="MYMouse"
"Scheme Source"=dword:00000002
"Arrow"="E:\\Application Project\\out\\MouseStyle\\Cursor.cur"
"Help"="E:\\Application Project\\out\\MouseStyle\\Help.cur"
"AppStarting"="E:\\Application Project\\out\\MouseStyle\\Working.ani"
"Wait"="E:\\Application Project\\out\\MouseStyle\\Busy.ani"
"Crosshair"="E:\\Application Project\\out\\MouseStyle\\Cross.cur"
"IBeam"="E:\\Application Project\\out\\MouseStyle\\Beam.cur"
"NWPen"="E:\\Application Project\\out\\MouseStyle\\Pen.cur"
"No"="E:\\Application Project\\out\\MouseStyle\\Unavailable.cur"
"SizeNS"="E:\\Application Project\\out\\MouseStyle\\Size Horz.cur"
"SizeWE"="E:\\Application Project\\out\\MouseStyle\\Size Vert.cur"
"SizeNWSE"="E:\\Application Project\\out\\MouseStyle\\Resize Right.cur"
"SizeNESW"="E:\\Application Project\\out\\MouseStyle\\Resize Left.cur"
"SizeAll"="E:\\Application Project\\out\\MouseStyle\\Resize All.cur"
"UpArrow"="E:\\Application Project\\out\\MouseStyle\\Alternate.cur"
"Hand"=hex(2):00,00
请问怎么刷新呢？
楼上大哥给的代码可以编辑通过，但是没有起作用啊？

Answer 4

palmax(南宫煌) 你的方法我也试过了不行。HKEY_CURRENT_USER\Keyboard Layout\Preload我是在这里修改输入法的顺序，修改后不能立即生效，需要注销一下才行。

To楼主: 如果你是用程序改的注册表,用我的那句:SystemParametersInfo(SPI_SETCURSORS,0,NULL,SPIF_SENDCHANGE);是没有问题的
楼主按下面的试试:HKEY hKey;
struct HKEY__*RootKey;
TCHAR *SubKey;
TCHAR *ValueName;
LPBYTE SetContent_S;

RegCloseKey(hKey);

MessageBox("鼠标主题转换已完成!","OK",MB_ICONINFORMATION);另Tora3(啄木鸟):不同的修改向系统发的消息是不同的,不能一概而论;修改输入法好象必须重启或注销

Answer 6

KillProcess 掉 explorer.exe
然后再 Createprocess explorer.exe

Answer 7

谢谢你palmax(南宫煌)朋友，
你说的方法可以实现，是我自己把ANI文件的路径给错了，：）
非常感谢你！
