ATL Predefined Symbols

These symbols are defined in the ATL header files, but they support standard Windows application functions and actions. These symbols are mainly used with dialog boxes. When you are working with dialogs and controls in the Dialog editor, these symbols will appear in the Properties window associated with common controls. For instance, if your dialog box has a Cancel button, that command will be associated with the symbol IDCANCEL in the Properties Window.

IDABORT	Control: Dialog box Abort button
IDC_STATIC	Control: Static control
IDCANCEL	Control: Dialog box Cancel button
IDIGNORE	Control: Dialog box Ignore button
IDNO	Control: Dialog box No button
IDOK	Control: Dialog box OK button
IDR_ACCELERATOR1	Resource: Accelerator table
IDRETRY	Control: Dialog box Retry button
IDS_PROJNAME	String: Current application name
IDYES	Control: Dialog box Yes button
