DialogProcAn application-defined callback function used with the CreateDialog and DialogBox families of functions. It processes messages sent to a modal or modeless dialog box. The DLGPROC type defines a pointer to this callback function. DialogProc is a placeholder for the application-defined function name.
EndDialogDestroys a modal dialog box, causing the system to end any processing for the dialog box.
GetDialogBaseUnitsRetrieves the system's dialog base units, which are the average width and height of characters in the system font. For dialog boxes that use the system font, you can use these values to convert between dialog template units, as specified in dialog box templates, and pixels. For dialog boxes that do not use the system font, the conversion from dialog template units to pixels depends on the font used by the dialog box.
GetDlgCtrlIDRetrieves the identifier of the specified control.
GetDlgItemRetrieves a handle to a control in the specified dialog box.
GetDlgItemIntTranslates the text of a specified control in a dialog box into an integer value.
GetDlgItemTextRetrieves the title or text associated with a control in a dialog box.
GetNextDlgGroupItemRetrieves a handle to the first control in a group of controls that precedes (or follows) the specified control in a dialog box.
GetNextDlgTabItemRetrieves a handle to the first control that has the WS_TABSTOP style that precedes (or follows) the specified control.
IsDialogMessageDetermines whether a message is intended for the specified dialog box and, if it is, processes the message.
MapDialogRectConverts the specified dialog box units to screen units (pixels). The function replaces the coordinates in the specified RECT structure with the converted coordinates, which allows the structure to be used to create a dialog box or position a control within a dialog box.
MessageBoxDisplays a modal dialog box that contains a system icon, a set of buttons, and a brief application-specific message, such as status or error information. The message box returns an integer value that indicates which button the user clicked.
MessageBoxExCreates, displays, and operates a message box. The message box contains an application-defined message and title, plus any combination of predefined icons and push buttons. The buttons are in the language of the system user interface.
