如何用程序删除win98下面的 C:/windows/History指定历史网址？ 好急阿，请个位帮忙吧 (100分)

请高手帮忙：如何用程序删除win98下面的 C:/windows/History指定历史网址？ 好急阿

注册表，查找，然后删除

gz

2K:
C:/Documents and Settings/用户名/Local Settings/History

98:
C:/windows/History

独门秘籍：）
procedure TzypNeoForm.btnDeltempClick(Sender: TObject);
var
lpEntryInfo : PInternetCacheEntryInfo;
hCacheDir : LongWord;
dwEntrySize : LongWord;
dwLastError : LongWord;
Begin
dwEntrySize := 0;
FindFirstUrlCacheEntry( NIL, TInternetCacheEntryInfo( NIL^ ), dwEntrySize );
GetMem( lpEntryInfo, dwEntrySize );
hCacheDir := FindFirstUrlCacheEntry( NIL, lpEntryInfo^, dwEntrySize );
If ( hCacheDir <> 0 ) Then
DeleteUrlCacheEntry( lpEntryInfo^.lpszSourceUrlName );
FreeMem( lpEntryInfo );
Repeat
dwEntrySize := 0;
FindNextUrlCacheEntry( hCacheDir, TInternetCacheEntryInfo( NIL^ ), dwEntrySize );
dwLastError := GetLastError();
If ( GetLastError = ERROR_INSUFFICIENT_BUFFER ) Then Begin
GetMem( lpEntryInfo, dwEntrySize );
If ( FindNextUrlCacheEntry( hCacheDir, lpEntryInfo^, dwEntrySize ) ) Then
DeleteUrlCacheEntry( lpEntryInfo^.lpszSourceUrlName );
FreeMem(lpEntryInfo);
End;
Until ( dwLastError = ERROR_NO_MORE_ITEMS );
Application.MessageBox('清除IE临时文件成功！','网络工具箱', MB_ICONINFORMATION+MB_OK)
end;

wql那种直接删文件的办法应该可以

其实好多的程序只要自己考虑一下就会有简单的办法解决了，
在注册表里查找相关的健值然后删除，，
删除文件的方法也可以，
应该的呵呵呵没有使用过

工具，Internet选项中有的什么都可以帮你清除的，按它的提示干就行了。

谢谢各位，但我要写成程序，请各位帮忙阿。

TO zhangkan：
谢谢你的回复，请问删除过去指定的历史网址吗，在IE地址栏不要显示已经删除的网址

要删除地址栏的网址可以试试下面的代码
procedure TForm1.Button1Click(Sender: TObject);
var
MyReg:TRegistry;
begin
try
MyReg:=Tregistry.Create ;
with MyReg do
try
RootKey := HKEY_CURRENT_USER;
OpenKey( '/Software/Microsoft/Internet Explorer', TRUE );
deletekey('TypedUrls');
createkey('TypedUrls');
finally
myreg.free;
end;
showmessage('IE地址栏网址清空完毕!,需重新打开IE后有效！');
except
showmessage('IE地址栏网址无法清空，请重启后再试!');
end;
end;
