Thanks so much for your help.I mean,for example,when one clicks a button named btnOK,something happens:

void btnOK_Click()
{
PromptOK("Button btnOK is clicked.");
}

In the ide,when I create a form with a button,I can not find out where to add the above code.

ALT+T or Assist(ALT+C) all tried but it does not help.

I see.

First of all, do you already have dialog class?

http://www.ultimatepp.org/reference$Layout.html

(beware, above example shows how to create your dialog class, not your case).

Anyway, as long as you have such class, simply put

myOKbutton = callback(btnOK_Click);

into constructor.

Note that in 99.99% cases, you will rather want to call a method of dialog, not global level function. That is what Alt+T is designed for. Also, as soon as you type THISBACK(, Assist++ will offer a list of methods...

Another relevant example:

http://www.ultimatepp.org/examples$Button.html

Just in this case, no layout is used. Anyway, using designed layout has very similar effect to adding "button" member variable and "Add(button.VCenterPos(20).HCenterPos(200));"...
