Be like next train of thought: The program can pass 40 minutes of every on schedul to be carried out automatically, receive a database repeatedly, whether does inquiry have match information accordingly. For example, in 2007-8-14 1:40, the program moves, join the Table of the database is expressed, search whether is there 2007-08-1401 in corresponding field: 00: The value of 00 (this value is Datatime type) . In 2007-8-14 2:40, the program moves, join the Table of the database is expressed, search whether is there 2007-08-1402 in corresponding field: 00: The value of 00 (this value is Datatime type) . There are two difficulties now, the first is how to make the process moves automatically (estimation should involve Timer to accuse, but won't be used occasionally ah - _- ! ! ) . As a result of,the 2nd is everyday date is different, how to update relative variable automatically, for instance I should search to the database whether to have 2007-08-1401: 00: This 00 are worth, then I must define a 2007-08-1401 above all: 00: The value of 00 gift is nice search, but how to make this value can automatic every hour hind is updated automatically (every updated date value and one hour value even at 0 o'clock too, . . . . . . Whether should use get systematic time? Whether should use get systematic time??
Alas, anxious died, elder people give directions fall. Do obeisance to withered.
