MI Dialog remove
Hi, all friends, I remember somedays before there is a post in our list about the dialog remove command. I did not save that mail. Now I have the same problem. I used 'dialog remove' in Mapbasic program, but the dialog did not remove after I call the procedure. It is still there at the background. Dose anybody know how to solve that? Thanks very much.

MI TIGER Files
Hi all friends, How can I read Census Bureau's TIGER/Line files into MapInfo? There are 17 files for each county in TIGER/Line files, each has a special meaning. I don't know if there is any command in MapInfo can be used to read those files. Thansk a lot.

MI Many thanks for the great help!
Great thanks to Jason Adam, Patrick Phillips, Simon Hume, Marc Pelosse, Martin Hodder, and all our list friends. My problem of moving objects in MapInfo was solved. Here I summarize the main three solutions: The most accurate way to accomplish that would be to first Export as a MID/MIF table. Open your MIF file in Notepad, and add the line: Transform 0,0,0,2000 'that's for %X, %Y, metresX, and metresY. Make sure your Projection clause line supports Meters for the MapUnits parameter (there will be a 7 in the first 2 or 3 digits). Now import the file back to MapInfo. One solution consists of exporting your tab file in DXF, and then import it and specify the parameters for the transformation. Look into the possibility of there being an Offset function of the feature.obj. This is easy to do with MapX and VB. Public Sub MoveFeature(Feat As MapXLib.Feature, FeatX_distance As Double, Y_distance As Double) Feat.Offset X_distance, Y_distance Feat.Update End Sub Thanks very much again for your great help.
