Inno Setup刷新桌面 [英] Inno Setup refresh desktop
问题描述
是否可以使用[Code]部分中的Inno Setup刷新桌面?
Is it possible to refresh the desktop using Inno Setup in the [Code] section?
是使用SendMessage还是以某种方式使用SHChangeNotify?
Either by using SendMessage or somehow use SHChangeNotify?
推荐答案
您可以通过在相应的DLL中调用Windows API中的任何函数来调用它.在此处中记录了Pascal DLL语法. SHChangeNotify 函数的文档是像往常一样在MSDN上找到.在Shell32.dll中可以找到此功能(不足为奇！).
You can call any function in the Windows API by calling it in the appropriate DLL. The Pascal DLL syntax is documented here. The documentation of the SHChangeNotify function is found at MSDN as usual. This function is found in Shell32.dll (no surprise!).
[Code]
const
SHCNE_ASSOCCHANGED = $08000000;
SHCNF_IDLIST = $00000000;
procedure SHChangeNotify(wEventID: integer; uFlags: cardinal; dwItem1, dwItem2: cardinal);
external 'SHChangeNotify@shell32.dll stdcall';
procedure SendChangeNotification;
begin
SHChangeNotify(SHCNE_ASSOCCHANGED, SHCNF_IDLIST, 0, 0);
end;
现在，您可以在任意位置调用SendChangeNotification，例如在事件函数中.
Now you can call SendChangeNotification anywhere you like, for instance in an event function.
