The Difference between install a control callback and setting it directly.

[DavidLee]

In cvi GUI programming , I can set a control callback function in the edit dialog , and also I can realize this by using "InstallCtrlCallback()" , I'd like to know if the 2 ways would have different performance ? Thanks.

No, performance should be exactly the same in the callback execution and response time to events.

This just means the execution performance is the same, when using "InstallCtrlCallback()" , the program have to experience a sequence of callback install procedure , I am afraid that this procedure would bring up a bad affection to the application loading process .
