I need to open an explorer window showing a specific folder, lets say "C:\\Windows" What function should I use to reach my goal? I'm using Windows so can use API, also I can use boost, but I can't use C++11.

Answer 1

You can use the SHOpenFolderAndSelectItems function to do this, rather than forcibly running Explorer yourself (what if the user has replaced Explorer as their default file manager, for example?).
LPCWSTR pszPathToOpen = L"C:\\Windows";
PIDLIST_ABSOLUTE pidl;
if (SUCCEEDED(SHParseDisplayName(pszPathToOpen, 0, &pidl, 0, 0)))
{
// we don't want to actually select anything in the folder, so we pass an empty
// PIDL in the array. if you want to select one or more items in the opened
// folder you'd need to build the PIDL array appropriately
ITEMIDLIST idNull = { 0 };
LPCITEMIDLIST pidlNull[1] = { &idNull };
SHOpenFolderAndSelectItems(pidl, 1, pidlNull, 0);
ILFree(pidl);
}
Alternatively, you can call ShellExecute on the folder directly to run its default action (which is normally to open in a browser window):
ShellExecute(NULL, NULL, L"C:\\Windows", NULL, NULL, SW_SHOWNORMAL);

An hour ago I just wrote similar function.
This function doesn't do 100% as you want, but you can use it to get that you want.
It opens explorer window and marks file you are pointing to. Lets say you specified "C:\Windows\System32" in this case you will have "C:\Windows" opened and System32 marked. If you want to go inside you need to use something like FindFirstFile. If directory is empty, my offered solution wouldn't work...
bool ExplorerGoTo (const String &Path)
{
TCHAR tcBuff[8] = {0};
lstrcpyn(tcBuff, Path.c_str(), 5);
String stParams = _T("/n, /select, ");
if( lstrcmpi(_T("\\??\\"), tcBuff) == 0 )
{
stParams += (Path[4]);
}
else
{
stParams += Path;
}
String stExplorer = _T("C:\\Windows\\explorer.exe");
//ExpandPath(stExplorer);
if (stExplorer.empty ()) stExplorer = _T("explorer.exe");
SHELLEXECUTEINFO shi = { 0 };
shi.cbSize = sizeof (SHELLEXECUTEINFO);
shi.lpVerb = _T("open");
shi.lpFile = stExplorer.c_str ();
shi.lpParameters = stParams.c_str ();
shi.nShow = SW_SHOW;
bool bRes = ShellExecuteEx( &shi );
if( bRes == FALSE && GetLastError() != 0 )
{
Sleep(200);
return ShellExecuteEx( &shi );
}
return bRes;
}
And never use system()
