I wanna make the load button gray after user pressed the button. you know, another load process will be executed after the current one is completed, if the load button is double-clicked. Karah
"I just want to know how keil gets rid of the problem for its AGDI interface." Presumably, they don't see it as a problem! I can't see it (yet) either - please explain: What exactly is your "problem" here? Again, what are you actually trying to achieve here?
what are you actually trying to achieve here? another load process will be executed after the first load is completed, if the load button is double-clicked.
OK, we will investigate if we can disable the LOAD function while there is another LOAD already in process. However, it looks not like a serious problem to me. Reinhard

"the casual click costs too much time." There must be innumerable buttons all over your Windows system that will cause trouble if you use them incorrectly! I think you just need to be more careful! Software development should be disciplined - not a "casual" activity
"Software development should be disciplined - not a "casual" activity " maybe you are right. ;-) I agree with you on this point.
