How to store permission binary sets


How to store permission binary sets

it fixes the issue I am trying to find a way to store permission informations into a SQL Server 2012 Database. My permissions are sets like this : , You should do something like this:
code :
[Flags]
public enum PermissionsB
{
    Aucun = 0,
    read = 1,
    write= 2,
    ssss = 4,
    tttt = 8,
    rrrr = 16,
}
[Flags]
public enum PermissionsB
{
    Aucun= 0b00000,
    read = 0b00001,
    write= 0b00010,
    ssss = 0b00100,
    tttt = 0b01000,
    rrrr = 0b10000,
}
PermissionsB permission = PermissionsB.read | PermissionsB.write;
int intPermission = (int) permission;
PermissionsB retrievedPermission = (PermissionsB) retrievedInteger;
bool canWrite = (retrievedPermission & PermissionsB.write) == PermissionsB.write;

To fix this issue Instead of splitting each permission into individual columns or sql server table we are rethinking of using Flag attribute to Enum for use with bit wise operations. Our application defines end points ( not the one from rest services) for accessing resources( read, modify, update) and each user is entitled with permissions for example Bob has permissions to Read, Modify resource X so when bob comes and accesses this resource we check if bob has permission x.Now that where we are going to apply this is clear here are my doubts , To answer your questions in order:
code :
var x = Permissions.Read | Permissions.Write;
if ((x & Permissions.Read) == Permissions.Read) { print "Success!"; }
[Flags]
enum Permissions {
  None =    0,
  Read =    0x001,
  Write =   0x010,
  Execute = 0x100,
  ReadWrite = Read | Write,
  // [snip]
}

Hope this helps You typically don't want to store large files in a relational database -- it's not what they're designed for. I would also advise against using a NoSQL solution, since they're also typically not designed for this, although there are a few exceptions (see below).
Your last idea, storing the files on the filesystem (do note that this is what filesystems are designed for ;) is most likely the right approach. This can be somewhat difficult depending on what your scalability requirements are, but you will likely want to go with one of the following:

wish of those help Apparently this is a bug in the Google Play Store as reported with issue 63898 and issue 63895, and it doesn't seem to be fixed yet.
So we can't do much about it, besides not using the maxSdk attribute or trying to avoid the permission in the first place.

To fix this issue If you're running in the android API version 23 or higher you'll need to require permissions at runtime. To ask for permissions you should do it right before using the feature that uses the permission:
code :
int MY_PERMISSIONS_REQUEST_LOCATION = 123;
if (ContextCompat.checkSelfPermission(thisActivity,
        Manifest.permission.ACCESS_FINE_LOCATION)
        != PackageManager.PERMISSION_GRANTED) {
    //app doesn't have permission yet

     ActivityCompat.requestPermissions(thisActivity,
                new String[]{Manifest.permission.ACCESS_FINE_LOCATION},
                MY_PERMISSIONS_REQUEST_LOCATION);
} else {
    // Permission has already been granted
}
public void onRequestPermissionsResult(int requestCode,
        String permissions[], int[] grantResults) {
    switch (requestCode) {
        case MY_PERMISSIONS_REQUEST_LOCATION: {

            if (grantResults.length > 0
                && grantResults[0] == PackageManager.PERMISSION_GRANTED) {
                // permission was granted
            } else {
                // permission denied
            }
            return;
        }

    }
}
