\c \\<b\\>on\\</b\\>|off|try|ifnewer|lastused
\c \\<b\\>on\\</b\\>|off|try|ifnewer|ifdiff|lastused
This command sets the overwrite flag which is used by the File command to determine whether or not the file should overwrite any existing files that are present. If overwriteflag is 'on', files are overwritten (this is the default). If overwriteflag is 'off', files that are already present are not overwritten. If overwriteflag is 'try', files are overwritten if possible (meaning that if the file is not able to be written to, it is skipped without any user interaction). If overwriteflag is 'ifnewer', then files are only overwritten if the existing file is older than the new file (note that when in 'ifnewer' mode, the destination file's date is set, regardless of what SetDateSave is set to).

Sets a background color and the text color for a static control, edit control, button or a dialog. Use GetDlgItem to get the handle (HWND) of the control. To make the control transparent specify "transparent" as the background color value. You can also specify branding instead of text color and background color to make the control completely gray. This is used by the branding text control in the MUI.
