I want to create an edit control that behaves in the following manner: While user is entering text in the edit control, when enter is pressed by the user, it clicks a button. I searched a lot but found nothing that helps. How to do it in C Win32 API.

The short answer is: "don't do that."

Create a dialog containing the edit control and button. Make sure the edit control's ES_WANTRETURN style is turned off, and the button's BS_DEFPUSHBUTTON style is turned on.

ES_WANTRETURN controls whether the edit control processes a carriage return/enter key (VK_RETURN keystroke). With it turned on, the edit control processes the keystroke itself (it becomes a new-line in the edit control). Probably obvious, but ES_WANTRETURN is generally only useful for a multi-line edit control.

With ES_WANTRETURN turned off, the enter/return keystroke is passed to the parent (the dialog box). That will process an enter as pressing the default button (if there is one).

Simply give the Button control the BS_DEFPUSHBUTTON style, then it will react to Enter presses automatically.

Otherwise, you would have to subclass the Edit control to catch WM_KEY(DOWN|UP) messages sent to it (don't catch them in the parent window's WndProc), check for VK_RETURN, and if detected then send a BM_CLICK message to the Button control.
