Thanks to those who responded about the workspace quirk, but I believe I have found the cause of the errors encountered saving a workspace. A bit more research and a sleep has let me identify the problem much more succinctly. I am still not sure of the solution, however.
It seems that there is some triggers in mapinfo that determines the version that a workspace is written to. The trigger that says that queries should be saved (and thus save the workspace as version 6) is not pulled if the queries are made in a Mapbasic program. Run the same code from the Mapbasic window, and the triggers are pulled and the workspace saves as it should. I have a simple Mapbasic program that demonstrates this if anyone is interested. you will need to change table paths, fields and selection examples to suit. Compile the code in MapBasic, run the program and look at the workspace. MapInfo will save the workspace as an earlier version and thus not save queries. I However, if you paste the same code into the Mapbasic window, you get the same result on the screen, but if you save the workspace at this stage, you get a version 6 workspace with queries and map included. I'd suppose the trigger to save the workspace as version 6 has been pulled when the code is run from MapInfo. If you have a simple mapBasic routine like this below: Declare Sub Main Sub Main 'Try pasting the code from here: 'XXXXXXXXXXXXXXXXXXXXX Close All Interactive Open Table "C:\FMapDemo2001\FMapTab\T_PAD_CUR.TAB" As Table1 Interactive Open Table "C:\FMapDemo2001\FMapTab\Labels\00036.TAB" As Table2 Interactive Select * from Table1 where C_Farm = "00036" into Selection1 Select * from Table2 where Column = "Block:SubBlock" into Selection2 Map From Selection1, Selection2 'XXXXXXXXXXXXXXXXXXXXX 'To here in the mapBasic window. End Sub You end up with a map of the two selection tables. Now if you save the workspace, you get: !Charset WindowsLatin1 Open Table "C:\Program Files\MapInfo\Professional 6.5\DATA\Map_Data\Austrlia\AUSTCAPS" As AUSTCAPS Interactive Open Table "C:\Program Files\MapInfo\Professional 6.5\DATA\Map_Data\Austrlia\AUSTRLIA" As AUSTRLIA Interactive In other words, all reference to the selections are lost, and the version of the workspace is not specified. However if you paste the code into the MapBasic window, select the code and run it. You get the same map as before, but this time if you save the workspace, you get the following. !Workspace !Version 600 !Charset WindowsLatin1 Open Table "C:\Program Files\MapInfo\Professional 6.5\DATA\Map_Data\Austrlia\AUSTCAPS" As AUSTCAPS Interactive Open Table "C:\Program Files\MapInfo\Professional 6.5\DATA\Map_Data\Austrlia\AUSTRLIA" As AUSTRLIA Interactive Select * from AUSTRLIA where STATE = "Queensland" into Selection1 noselect Select * from AUSTCAPS where Place_Name = "Brisbane" into Selection2 noselect Map From Selection2,Selection1 Position (0.40625,0.53125) Units "in" Width 5.29167 Units "in" Height 2.80208 Units "in" Set Window FrontWindow() ScrollBars Off Autoscroll On Set Map CoordSys Earth Projection 1, 0 Set Map COmmand continues......... In other words, running the same code in MapInfo has triggered a need to save the workspace as version 6 and thus you get all the queries. Anyone think of a way of pulling the trigger in code?
