WM_SETTEXT Overview  Group

An application sends a WM_SETTEXT message to set the text of a window.

WM_SETTEXT 

wParam = 0;                     // not used; must be zero 

lParam = (LPARAM)(LPCTSTR)lpsz; // address of window-text string 

 

Parameters

lpsz
Value of lParam. Points to a null-terminated string that is the window text.

Return Values

The return value is TRUE if the text is set. It is FALSE (for an edit control), LB_ERRSPACE (for a list box), or CB_ERRSPACE (for a combo box) if insufficient space is available to set the text in the edit control. It is CB_ERR if this message is sent to a combo box without an edit control.

Default Action

The DefWindowProc function sets and displays the window text.

Remarks

For an edit control, the text is the contents of the edit control. For a combo box, the text is the contents of the edit-control portion of the combo box. For a button, the text is the button name. For other windows, the text is the window title.

This message does not change the current selection in the list box of a combo box. An application should use the CB_SELECTSTRING message to select the item in a list box that matches the text in the edit control.
