CodePudding user response:

Use timer polling, every once in a while go to check the database, found that less than the critical value of alarm,

CodePudding user response:

How do you achieve specific please? Can you give an example? thank you

CodePudding user response:

So can't!
In the timer event, timing to perform!

If the current inventory & lt;=the critical value of this item then
Messagebox (', ')//alarm
End the if

Still don't understand, the window is not a timer events, open it, inside written judgment

The guidance of the above thank you!!!!!!!!!! There is a problem, ask again

This functional comparison affect application performance, you'd better somewhere in the program interface a allows the user to select whether to enable the detection function, such as large amount of data, the function of program performance, can let users to disable this feature, province in let you change program, then the best to do a manual check inventory is lower than the critical value of the function, automatic check inventory is lower than the critical value of the function is called the hand to check the function of inventory is lower than the critical value, the automatic check inventory level is lower than the critical value of the function is disabled, the user can also manually by the inventory is lower than the critical value for the query, ha ha, is like a tongue twister
