RE: [MI-L] Make a whole in a region object
Title: RE: [MI-L] Make a whole in a region object Well, if you need to do this 100 times a day, I can see a need for a tool that makes this process easier. 1. Draw hole with special tool - 1a. The hole searches for objects in a certain layer, could be the editable layer - 1b. For each found object, it erases the part of the object, that is within the hole 1 step is a lot easier than 7 ;-) And I can even give you some part of the code, bear with me as I don't have MapBasic Help or my normal editor here to help me check the spelling and the defines and functions used: Sub ToolEraser '**This is the procedure called by your toolbutton, '**that should have a POLYGON draw_mode Dim oEraser, oToBeErased As Object, nMID, nRowID As Integer, sLayer As String oEraser = CommandInfo(CMD_INFO_COSTUM_OBJ) nMID = FrontWindow() '**Check that the frontwindow exists and is a mapper sLayer = MapperInfo(nMID, MAPPER_INFO_EDITABLE_LAYER) Select * from sLayer Where OBJ Intersects oEraser Into OBJS__TO__ERASE NoSelect Fetch First From OBJS__TO__ERASE Do Until EOT(OBJS__TO__ERASE) nRowID = OBJS__TO__ERASE.ROWID oToBeErased = OBJS__TO__ERASE.OBJ oToBeErased = Erase(oToBeErased, oEraser) Update OBJS__TO__ERASE Set OBJ = oToBeErased Where ROWID = nRowID Fetch Next From OBJS__TO__ERASE Loop End Sub This is pretty much what you need. I you want to store the Eraser object, you just need to insert that into a layer at the end of the procedure HTH, Peter Horsbøll Møller GIS Developer, MTM Geographical Information & IT COWI A/S Odensevej 95 5260 Odense S.

RE: [MI-L] MapBasic - Expanding Munged filenames on the MapInfoRecentFiles menu
Title: Re: [MI-L] MapBasic - Expanding Munged filenames on the MapInfoRecentFiles menu I see two possible places to store that information: 1. The MapInfow.prf where MapInfo normally stores the preferences 2. The Registry Unfortunately I'm at the moment sitting at a computer with no MapInfo installed (!!!), so I can't test it Peter Horsbøll Møller GIS Developer, MTM Geographical Information & IT COWI A/S Odensevej 95 5260 Odense S.

[MI-L] Changelog tracking?
Hello all, I am curious what others are using to track changes to MapInfo files and workspaces. We have run into an issue where a lack of change tracking is making troubleshooting more difficult. I dont think we would need a full blown version control system but something more along the lines of a changelog or change tracker. Is anyone doing something like this when files are being modified by multiple programmers/users? Thanks, Jonathan ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
