Checking for permissions for SHBrowseForFolder similar to GetSaveFileName, C++ / Win32

Question

I have a program that uses both SHBrowseForFolder, GetSaveFileName.

When I use GetSaveFileName and the directory chosen doesn't have the right permission it automatically shows an error that the current user doesn't have the proper permission.

I need a checking similar to this to happen when I use SHBrowseForFolder.

Have tried CreateDirectory but it succeeds if the directory chosen is C:, while GetSaveFileName would only allow admins to write here.

Answer 1

You can check permissions using this:

1. GetProcessToken
2. GetTokenInformation (to get the tokenuser and SID for the user)
3. GetNamedSecurityInfo (to get the DACL for the given folder) and
4. BuildTrusteeWithSid(pTrustee, pSidUser);
5. GetEffectiveRightsFromAcl
