• Federated Identity- Windows Identity Server - disable cookies in the browser

  - by vinoj

  Hello, I see that Federated Identity stores Security token to a cookie, after its first request to the STS(Secure Token Service). In that case if I disable cookie in my browser, how does it work.

• iPhone - Have the keyboard slide into view from the right like when editing a note in Contacts

  - by Toon Van Acker

  Hello, I'm looking for a way to slide the keyboard into view from the right, like what happens in the Contacts application when you edit a note. My problem is that when I call [someTextView becomeFirstResponder] in viewWillAppear, the keyboard immediatly pops up with no animation. And when I call it in viewDidAppear, the view first slides in from the right (UINavigationController does the sliding), and then the keyboard slides in from the bottom. Is it possible to have the keyboard slide in from the right, together with the view?

  - by Industrial

  Hi everyone! Doing my first tryouts with foreign keys in a mySQL database and are trying to do a insert, that fails for this reason: Integrity constraint violation: 1452 Cannot add or update a child row: a foreign key constraint fails Does this mean that foreign keys restrict INSERTS as well as DELETES and/or UPDATES on each table that is enforced with foreign keys relations?

• MIPS Assembler Instruction parameters

  - by Martin K.

  Hi, why does such a instruction as mul $t1, $v0 , 4 evaluates as expected. But mul $t1, 4 , $v0 results in a syntax error! I wonder why the first one works, because mul only works with registers per default, so I expect that only a solution like this will be workin li $t1, 4 # set $t1 = 4 mul $t1, $v0 , $t1 # set $t1 = 4 * n I'm using the SPIM simulator.

• Cannot truncate table because it is being referenced by a FOREIGN KEY constraint?

  - by ctrlShiftBryan

  Using MSSQL2005, Can I truncate a table with a foreign key constraint if I first truncate the child table(the table with the primary key of the FK relationship)? I know I can use a DELETE without a where clause and then RESEED the identity OR Remove the FK, truncate and recreate but I thought as long as you truncate the child table you'll be OK however I'm getting a "Cannot truncate table 'TableName' because it is being referenced by a FOREIGN KEY constraint." error.

• Python slicing a string using space characters and a maximum length

  - by chrism

  I'd like to slice a string up in a similar way to .split() (so resulting in a list) but in a more intelligent way: I'd like it to split it into chunks that are up to 15 characters, but are not split mid word so: string = 'A string with words' [splitting process takes place] list = ('A string with','words') The string in this example is split between 'with' and 'words' because that's the last place you can split it and the first bit be 15 characters or less.
