Recently, I have a small white, the school to write a short term with the front-end database, I use the SQL server + c + + MFC written
Write MFC window of time, I in the click of a button in response to an event in the face of the database for an update, then close the current window and open a new window, a new window initialization function to a select database lookups,
Problems come, I select out data has been update the previous data, why is this so, the update operation should not select before? For big solutions, how to solve this problem?

CodePudding user response:

2, inside the window display event, select data,
3, put a timer, window update regularly,
