SHBrowseForFolder

I need to use SHBrowseForFolder but have not been able to locate what I need to get the required behavior. It seems pretty simple, I need the routine to open as if the root of the dialog is the desktop so you see all the users drives, shares, etc. but I need to to open a folder. For example the user may be working in folder c:\A1, so when the folder dialog opens, you see all the drives, shares, etc, but the c:\A

<hmmm, hit something on the keyboard and it submitted my question???> anyway, I need the c:\A1 directory to be open as the selected directory. Currently when I set the root, it does not show any directories above or at the same level as the root. So if I set c:\A1 as root, the user can only see directories below A1. Is there something simple I am missing, it seems what I am looking for would be the default behavior.

Thanks in advance

As far as I remember there is no way, because that is the designed behavior of SHBrowseForFolder.

It's possible by using a callback.

Code:

---

BROWSEINFO browseinfo;
// Fill in your browseinfo
...
// Add these
browseinfo.lParam = reinterpret_cast<LPARAM>(pszFolder);
browseinfo.lpfn = &SHBrowseForFolderCallbackProc;

---

where pszFolder is a pointer to a TCHAR containing your folder to open.
The callback function

Code:

---

int CALLBACK SHBrowseForFolderPIDLCallbackProc(HWND hwnd, UINT uMsg, LPARAM lParam, LPARAM lpData)
{
        if (!lpData || !::IsWindow(hwnd))
                return 0;

        switch (uMsg)
        {
        case BFFM_INITIALIZED:
                // Set the initial folder
                ::SendMessage(hwnd, BFFM_SETSELECTION, TRUE, lpData);
                break;
        }
        return 0;
}

---

Change the TRUE in the sendmessage to FALSE when lpData is a PIDL.
