If I could do that then no need of your help

| As I said in answer to your earlier post, the message "Installation failed" gives no clue as to what might be wrong, so there is no way we could begin to guess what the error is.

Oh Yeah? You must be happy for all the help you are getting here. You talk as if you are paying to get help from people here.

Perhaps you can start your console window as an administrator - it may help.
Browse to your \Windows\system32 folder, then right-click on cmd.exe and choose "Run As Administrator".
Hope it helps.Karl - WK5M

Hi,
When you install a device driver and the installation fails you can check the SetupAPI Log File[^] located at %windir%\inf\setupapi.dev.log on Windows Vista and above.
My guess is that you are attempting to install a 32 bit device driver on a 64 bit Vista OS.
Best Wishes,
-David Delaune

In a program I develop I need to find out if I can have write rights to a given file. Earlier I have used
dwAttributes = ::GetFileAttributes(sFileName);
if( dwAttributes != INVALID_FILE_ATTRIBUTES )
{
if( dwAttributes & FILE_ATTRIBUTE_READONLY )
{
bReadOnly = true;
}
}

Your program should require elevation to gain access to such folder, see, for instance [^].

Did you answer to the right message? Your reply seem to have nothing to do with what I asked about.

| The issue is with User Access Control. If you wish to write to files in certain directories you need elevated access rights before you are allowed to do so. Did you read the link that Carlo gave you? txtspeak is the realm of 9 year old children, not developers. Christian Graus

Did you read the original question? I do not want to write files. I want to know if I can write files. i.e. I have a file name and want to be able to answer the question "Can I write to this file?".
I'm looking into using GetNamedSecurityInfo() and then GetEffectiveRightsFromAcl()

No problem.
I have found and used this code
bool sysAccessWrite(const LPWSTR path)
{
DWORD result;
SECURITY_INFORMATION secInfo = DACL_SECURITY_INFORMATION;
PSECURITY_DESCRIPTOR secDesc;
PACL dacl;
TRUSTEE trustee;
ACCESS_MASK rights;
result = GetNamedSecurityInfo( path, SE_FILE_OBJECT, secInfo,
NULL, NULL, &dacl, NULL, &secDesc );
if( result != ERROR_SUCCESS )
{
return false;
}
trustee.pMultipleTrustee = NULL;
trustee.MultipleTrusteeOperation = NO_MULTIPLE_TRUSTEE;
trustee.TrusteeForm = TRUSTEE_IS_NAME;
trustee.TrusteeType = TRUSTEE_IS_USER;
trustee.ptstrName = _T("CURRENT_USER");
result = GetEffectiveRightsFromAcl(dacl, &trustee, &rights);
if( result != ERROR_SUCCESS )
{
return false;
}
(void) LocalFree(secDesc);
return (rights & GENERIC_WRITE) ? true : false;
}
The problem is that it should work, but it don't. At least not when I try it under Windows 7. It gives 1F01FF (Full control) even if the program isn't capable of actually writing to the file.

Can you not open the file using CreateFile(GENERIC_WRITE, ...)? If that fails, then you know that writing to the file is not possible."One man's wage rise is another man's price increase." - Harold Wilson

Good idea. I would not know exactly why it failed, but it would work for now. Thanks for the tip.

Just check the return value from GetLastError()."One man's wage rise is another man's price increase." - Harold Wilson

The return value when it fails is just a INVALID_HANDLE_VALUE and if I use GetLastError() I don't get a lot of more info. Just a ERROR_ACCESS_DENIED and that can mean several things. However it may be enough for what I'm trying to do. If the file is not tagged as read only and I still can't open it for writing it probably some issue with rights.

So your problem has nothing to do with UAC?

Not as such. I want to know if I can write to a file. I'm not interested in actually writing to the file so elevation is not what I'm looking for. I have found Check User’s Permissions On A File or Folder[^] that seem to do about what I want to do.
