Synchronizing stored procedures in mysql -

i have 2 applications, both of them using same stored procedure in mysql. procedure synchronized, while 1 applications calls it, other 1 has wait. is there way without altering codes of applications (that modifying stored procedure)? thanks, krisy you can absolutely within stored procedure without changing application code, bear in mind you're introducing locking issues , possibility of timeouts. use get_lock() , release_lock() take care of synchronization. run get_lock perform synchronization @ start of stored procedure, , release_lock once you're done: if (get_lock('lock_name_for_this_sp', 60)) .... body of sp release_lock('lock_name_for_this_sp'); else .... lock timed out end if you'll need take care application timeouts longer lock timeout don't incur other problems.

C# do some work after all events are raised (or combine events) -

i'd subscribe event raised when of multiple other events raised. suppose have multiple tasks ( a ) first (for example animating multiple independent views), can subscribe event task complete, , i'd other work ( b ) after of these events finished. the amount of first tasks ( a ) can differ each time, @ moment set counter number of tasks a , subscribe n events, , in event handler task completion decrement counter, , when it's zero, task b. is there nicer way combine these events using counter? if understand question correctly, increment counter when start tasks , when each task completed, decrement counter in event handler. in event handler, check see (after decrementing counter) if counter zero. if so, task b. i suggest @ tasks ( aka "task parallel library (tpl)" ), allows this: task.whenall( new task[] { task.run(()=> { //... work a1... }, task.run(()=> { //... work a2... }, task.run(()=> { //... work a3... }}) .con...

html - Passing file type variable from one external javascript to another external javascript -

-
is possible? saw lot of questions passing values 1 external js external js, didn't (or maybe didn't notice) see passing file 1 external js another. the thing is, building web page consisting of 3 pages on it. first page uploading file using drag , drop, 2nd page formdata input , submitting formdata using ajax, while 3rd page show responsetext ajax. each page has own external script, because if try cram codes 1 external javascript, show error cannot call method 'addeventlistener' of null whenever moved 2nd or 3rd page, because drag , drop box located on 1st page. but need file dropped external js handles 1st page external js handles 2nd page, because need append file along other data formdata, before submitting ajax. want know if there anyway can pass file (along file info obtained filereader) external js 1st page external js 2nd page? , if possible, method doesn't involve server side scripting (like php, jsp).
