BCGControlBar Pro for MFC
void CBCGPEdit::EnableBrowseButton ( BOOL  bEnable = TRUE,
LPCTSTR  szLabel = _T("...") 
)

Enables or disables the browse button.

Use this method to enable or disable the browse button. If you set bEnable to TRUE, you'll need to derive a class from CBCGPEdit and override CBCGPEdit::OnBrowse in order to execute a custom browse action.

If you set bEnable to FALSE, the browse button will be removed from the edit control.

Parameters
bEnableAdds or removes the browse button to/from the edit control.
szLabelA text string to be displayed on the browse button (for example, "...").
