How to read 'MODIFY' File/Folder permission

Hello All,

I have a query regarding File/Folder permissions.

I have a folder on which a particular user don’t have ‘MODIFY’ permission.
I want to read programmatically whether the particular user has the ‘MODIFY’ permission on that folder on not.

Currently I am using following code.

res = _waccess( L"E:\\3D Library\\Temp.txt”, 06 );
Temp.txt is a file in the Folder on which user dont have 'MODIFY' access rights.

This is returning the same value for all users irrespective of the MODIFY permission.
I wanted to use ‘GetFileAttributes(…)’ but I don’t understand how to use it to read ‘MODIFY’ permission.

My query is:
How read the ‘MODIFY’ permission?

Please help.

Thanks,

To query and set we can use
GetFileAttributes and SetFileAttributes respectively.

dwAttrs = GetFileAttributes(FileData.cFileName);
if (!(dwAttrs & FILE_ATTRIBUTE_READONLY))
{
SetFileAttributes(szNewPath,
dwAttrs | FILE_ATTRIBUTE_READONLY);
}

For user permission on particular folder try this

Check User’s Permissions On A File or Folder[^]

Thanks For the response.

I can check the read access using this method.
But I want to specifically check the "MODIFY' access.

Is there any way to check the "MODIFY" access.

Thanks...

if you want to check whether you have MODIFY permission on a folder then call GetFileAttributesEx API

check whether FILE_ATTRIBUTE_READONLY is not set, else you can write and delete, that means, you can modify. Smile | :)

This information is incorrect. A file can have the read-only attribute not set, but if write permission has been denied, you will not be able to modify it.

Attributes are not the same as permissions, so GetFileAttributes() is not going to do you any good. You'll need to query the file's ACL. Check out GetFileSD(), GetSecurityDescriptorDacl(), GetAclInformation(), and GetAce().

As per the MSDN it should like below:-

BOOL CMainFrame::PreCreateWindow(CREATESTRUCT& cs)
{
if( !CFrameWnd::PreCreateWindow(cs) )
return FALSE;
if(NULL != cs.hMenu )
{
::DestroyMenu(cs.hMenu); // delete menu if loaded
cs.hMenu = NULL; // no menu for this window
}

return TRUE;
}

What does it display instead of Arabic letters? Question marks or some garbage character?

Hi Rajesh,

So, if it doesn't display question marks, it could be as simple as that the machine is not having the language pack installed. Have you tried Michael Schubert's suggestion? I didn't suggest it right away to ensure that you weren't seeing question marks instead.

Well, I'm not sure. I've never worked with Arabic characters, but have you checked if it's got anything to do with setting the "reading direct order"? (Arabic is right to left).

I think you have to install the language and font support in Windows:
Control Panel -> Regional and Language Options -> Languages -> Install files for complex script and right-to-left languages
