Displaying Message Box while program(code) continues [modified]

[KongHL]

Hmm I mean doModal(), then call a function of that dialog class immediately after the dialog is being displayed. Is it possible?

This goes against the concept of a message box. One way you could get this effect is to display the message box in another thread. It might be simpler to make your own modeless dialog however. Steve

you can write your funtion in OnShowWindow ; But still it won't fulfill your purpose as you want to call the funtion after the dialog is displayed. In that case I have two options. First in the OnInitDialog function you call SetTimer to set time say 1 sec. Then call your funtion in OnTimer and kill the timer in OnTimer function. Second method is that you create a thread to call your funtion. and start the thread in OnShowWindow. Regards Anil

Please have a look on Mauro Leggieri's Background Task Dialog[^] Good luck and keep the good coding!

Create the ModelLess Dialog box!

very bad idea...!! consider the case where you init your dialog with a database which it connection is long to establish (at least more that 1 sec)... the program will behave badly.

Yes you are right:-), Its a bad idea, depending on the situation. But the programmer know what he wants, and aware of the conditions. if the condition is according to you then we can use thread instead. But I think still I can make it to work.

void OnShowWindow(){
  // here I set timer
  SetTimer(....);

 // Then the database connection
 // Its long enough 1 sec 
 // problem .....

  return;
}

second case

void OnShowWindow(){
  // Then the database connection
 // Its long enough 1 sec 


  // here I set timer
  SetTimer(....);  // less chance of problem
  return;
}

It depends on when you set the timer. But I still agree with you that its a bad idea. But is one of the solution depending on the situation. Regards Anil -- modified at 5:25 Friday 2nd June, 2006
