SHBrowseForFolder打开文件夹时，每次都是从根目录打开。当要给好多路径参数的时候，当数据都放在嵌套很深的夹子里的时候，非常讨厌 SHBrowseForFolder打开文件夹时，记住上一次打开的路径 ~~~

<不像CFileDialog会自动记住上次路径~>

搞法：

1.定义全局变量 LPITEMIDLIST global;

2.添加回调函数

static TCHAR szdir[MAX_PATH];
INT CALLBACK BrowseCallbackProc(HWND hwnd, UINT uMsg, LPARAM lp, LPARAM pData)
{
LPITEMIDLIST tmp = (LPITEMIDLIST)pData;
switch(uMsg)
{
case BFFM_INITIALIZED:
      SendMessage(hwnd, BFFM_SETSELECTION, TRUE, (LPARAM)szdir);
break;

case BFFM_SELCHANGED:
    // Set the status window to the currently selected path.
if (SHGetPathFromIDList((LPITEMIDLIST) tmp ,szdir))
{
    SendMessage(hwnd,BFFM_SETSTATUSTEXT,0,(LPARAM)szdir);
}
break;
}
return 0;
}

3.打开button ::OnBUTTON()中写：

LPITEMIDLIST idl = NULL;

BROWSEINFO bi ={0};

char name[MAX_PATH];

ZeroMemory(&bi, sizeof(BROWSEINFO));

bi.hwndOwner = AfxGetMainWnd()-> GetSafeHwnd();

bi.pidlRoot = NULL;

bi.pszDisplayName = name;

bi.lpszTitle = "选择文件目录";

bi.ulFlags = BIF_RETURNONLYFSDIRS;

bi.lpfn = BrowseCallbackProc;

bi.lParam = (LPARAM)global;

idl = SHBrowseForFolder(&bi);

global = idl;

SHGetPathFromIDList(idl, XXX.GetBuffer(MAX_PATH));

XXX.ReleaseBuffer();

Cwnd* pWnd = NULL;

pWnd = GetDlgItem(IDC_XXXXX);

if(pWnd)

{

pWnd->SetWindowText(XXX);

}
