Re: MI MB: Latest Agony
I'm trying to make a single polygon in a single table change colors using MB and I can't seem to find the right MB incantation to make it happen. All I want is to have the single selected polygon on the top layer of my map window be a distinct color from the other polygons around it. And I'd like it to be the same color every time the program fetches a new single polygon and puts that one on top of the layer control pile. Does one of the MB experts in the crowd have a minute to brief me on this? These four lines change the selected object to solid green Dim o As Object o = Selection.Obj Alter Object o Info 3, MakeBrush(2, RGB(0,255,0), RGB(0,0,0)) Update Selection Set Obj = o I don't know how your "program fetchs a new single polygon and puts that one on top of the layer control pile", but you'll likely need a similar combination of Alter Object and Update statements. -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]

This may help Dim a as object Select * from your table where criteria to select the object into temptable a = selection.obj ALTER OBJECT a INFO 3, MakeBrush(1, CYAN, BLUE) UPDATE TempTable set obj = oDMA where rowid = 1 Commit table your table interactive note Makebrush command format = (pattern, forecolour, backcolour) Ian - Original Message - From: Tim Rood [EMAIL PROTECTED] To: [EMAIL PROTECTED] Sent: Wednesday, July 05, 2000 6:02 PM Subject: MI MB: Latest Agony I'm trying to make a single polygon in a single table change colors using MB and I can't seem to find the right MB incantation to make it happen.

You might try swallowing a live toad before sitting down to your next MapBasic session. Then comparatively, the rest of the day will seem pretty pleasant. Anyway, here's how to do this: First you have to get access to the record with the polygon you want to change. There's lots of ways to do this (see SQL select, SelectionInfo(), fetch, etc.), but let's say the record cursor is pointing at it, and the table is called POLY. '--- dim objPoly as object dim brushPoly as brush 'you need to include mapbasic.def for color definitions brushPoly = makeBrush (2, YELLOW, WHITE) objPoly = POLY.obj nRow = POLY.rowid alter object objPoly info OBJ_INFO_BRUSH, brushPoly update POLY set obj = objPoly where rowid = nRow '--- What I didn't understand when I was first struggling with this myself is that you have to "update" the table or nothin shows. Also notice the "where rowid = nRow" bit. Leave this off and ALL you records get changed to this object. - Bill Thoen GISnet, 1401 Walnut St., Suite C, Boulder, CO 80302 tel: 303-786-9961, fax: 303-443-4856 mailto:[EMAIL PROTECTED], http://www.ctmap.com/gisnet -- To unsubscribe from this list, send e-mail to [EMAIL PROTECTED] and put "unsubscribe MAPINFO-L" in the message body, or contact [EMAIL PROTECTED]
