asp.net - Autopostback=True for a Textbox and RequiredFieldValidator next to it. But when submitting form after Posting back by TextChanged event to the Textbox, RequiredFieldValidator doesn't work? -

मेरे। एस्पेक्स फॉर्म में मेरे पास एक टेक्स्टबॉक्स है (टेक्स्टबॉक्स 1) Autopostback = True के साथ मैंने इसके आगे एक आवश्यक फ़ाइल्डवैलिडेट (आवश्यक फ़ील्डवैद्येटर 1) सेट किया है। लेकिन जब पाठ बॉक्स 1 की टेक्स्ट-चंचल घटना से पोस्ट करना आवश्यक है, तो आवश्यक फ़ील्ड वैलिडेटेटर 1 प्रकट होता है, लेकिन फिर भी मैं टेक्स्टफ़ॉक्स 1 में अपना कुछ भी नहीं जमा कर सकता हूँ! "पोस्ट-टेक्स्ट" आइटमप्रॉप = "टेक्स्ट">

आपको टेक्स्ट बॉक्स के कारण वैधता संपत्ति को सही पर सेट करना होगा (यह पाठ बॉक्स के लिए डिफ़ॉल्ट रूप से गलत पर सेट है)।

sql server - SQL Query - Delete duplicates if more than 3 dups? -

-
Is there an elegant SQL statement for deleting duplicate records in a table, but only if X is the number of duplicates? So it allows up to 2 or 3 duplicates, but what is it? At present I have a statement that does the following: Remove table from table, left outer (duplicate from table group like Triad, Diplo 1, Duplex 2) 1, Select Max (ID) by Dupl 2. Maintenance as TDI) = Maintenance. Where are kept. Road is empty This works very well. But what I want to do now will only remove those lines, if they have more than 2 duplicates. Thanks with in the form of CT (select row_member ( )) (Divol1 by split, dupol2 sequence by id) from table as rn) from cte where rn & gt; 2; - or & gt; 3 etc. The query is being classified by a 'line number' for each record, (Dupl 1, Dupl 2) and ordered by ID. In fact, this line number is calculated as 'duplicate', which has the same duplicate 1 and duplex 2 and then specifies the number 1, 2, 3. If you want to keep ...

c - Different access levels with PAM -

-
Currently I have a graphical application that has two levels of access, operator and administrator. Login and authentication are all homemade and I want to switch applications using PAM instead. I'm not sure what is the right way to do this. Correct me if I am wrong, but it looks like PAM boils down to "yes" or "no" to check - yes you can use this service, or you do not There is no provision based on the various levels of admission in which the user is logging on. I should be able to tell who is the operator and who is the administrator, though, and it is possible that I probably want to be able to do this through PAM. / P> So my idea is that I have two services with two different configurations , /etc/pam.d/pamdemo and Administrator /etc/pam.d/pamdemo-admin My application will then try to authenticate before pamdemo-admin , and if it is unsuccessful then pamdemo . If both fail, then admission is denied. Am I on the right track or am I complete...
