Hi Sam
There are a few things to keep track of on the layout.
First of all, you have the frames. They have their own IDs starting from 1. Every time you add a frame, it will be given the next number. MapBasic also has a function that will tell you how many frames a layout has.
A few examples where we assume the front window is a layout.:
'**Get the WindowID of the LayoutnLayout_WID = FrontWindow()'**Get the number of frames on the Layout'**If your layout has multiple pages, this will only get the elements from the current page.nNumFrames = LayoutInfo(nLayout_WID, LAYOUT_INFO_NUM_ITEMS)When you know how many frames, you have, you can loop through these to find the frame you are looking for
'**Looping thru the frames, searching for mapsFor nFrame = 1 To nNumFrames If LayoutItemInfo(nLayout_WID, nFrame, LAYOUT_ITEM_INFO_TYPE) = LAYOUT_ITEM_TYPE_MAPPER Then nMapper_WID = LayoutItemInfo(nLayout_WID, nFrame, LAYOUT_ITEM_INFO_WIN) End IfNextMapBasic also has a function that helps you locate a frame by its name:
'**Searching for a map frame named "TheMapFrame"nMapframe_ID = LayoutItemID(nLayout_WID, "TheMapFrame", LAYOUT_ITEM_TYPE_MAPPER)The ID of the frames or static once you have created the frame. They don't get renumbered if you for example delete the first frame. They do get renumbered when you save the layout to a workspace and reload the layout from the workspace.

Subject: Getting number of frame within a layout?
Hello,
For my MapBasic 2019 code, I am having trouble figuring out how to identify the number of a window when it is a frame within a layout (designer). I have created a multi-page layout with various maps and other frames like legends, text, symbols, etc. Every time I add an item to the layout, I believe it has its own window number, but I can't seem to figure out how to identify/track the window numbers so I can do things like, for instance, set map window zoom entire for a mapper window in a particular frame . I have tried the frontwindow command, but that always just gives me the number of the layout window itself.
Thanks,
Sam
