MI MultiListBox - Just how does that work......
I am trying to use the MultiListBox command in MapBasic and have set up the control in the dialog but can't figure out a way to return entries from the list box. What I am trying to do is query a temporary table that summarises entries in a column and populates a multi list box. This part works well and I can populate the multi list box with what I want from a temporary table. The problem I have is that I can't figure out how to trap the selections in the multi list box (I want to use what the user chooses to limit what a sql query selects). I have already tried to call a handler routine (from the dialog) and have played around with the ReadControlValue command, but it isn't clear from the MapBasic manuals how exactly to trap mulitple selections made in a multi list box. Eventually I want the code to provide me with string values that match the entries selected from the multi list box. Any help most gratefully received.

MI Vertical Mapper
Hello members, I've got two questions for your knowledge : - Is Vertical Mapper able to create some 3-D objects (with x;y;z1;z2 coordonates) or does it only make some 3-D surfaces - If someone knows the BD TOPO edited by IGN (France). Does this Data Base generate a three-dimensionnal representation with Mapinfo? Thank for your replies Laurent SCHNELL ___ Vendez tout... aux enchères - http://www.caraplazza.com
MI Printer memory
This is not strictly a MapInfo question but perhaps someone can help. I have a HP1050C printer which has 32Mb memory which has been adequate for most of the maps that have been printed. There have been occasions where difficulties have arisen when printing detailed A1 or A0 size maps (with raster backgrounds). I understand that the printer can be upgraded to resolve the problems by either adding more memory or by adding a hard disk drive (or both). The question is, which would be most cost effective? What benefits does the hard disk option give over the additional memory option? Any help would be appreciated.

RE: MI Copying Boundary Lines.
Or the other one is a digitising trick but as effective (sometimes) switch the node snapping on - (hit s), select the polygon tool then move the cursor over the first point you want to digitise from, get the snapping cross hairs to appear and click to create a new node. then move to the last point on the existing polygon you want to digitise to and again move the cursor over the point so that the snapping 'cross haris' appear - then hold down shift whilst clicking. the boundary of the new oject will automatically 'snap' along the entire lenght of the new object between the 'start' and 'end' nodes. i find it better to do this is in a couple of stages than all at once.

Hi Myles I find the easiest way to do this is in fact not to digitise it. Instead digitise a polygon that goes inside the original polygon, set the target to the new polygon, select the existing polygon(s) and use these to erase the overlap. The result is that the new polygon exactly agrees with the existing polygons. (Either that or you get the dreaded "error overlaying objects" message which indicates that the original data isn't as clean as you thought) simply and stacks quicker than digitising all the little bits.

What is the best way of copying a piece of this regions boundary so that when I digitise another region adjacent to it, they have identical boundaries? Any help would be much appreciated.

MI Median Household Income
Hello list, I am creating demographic maps based on Median Household Income and population. I was wondering if someone knows of a place that creates classifications such as lower class, middle class, upper class, etc. for income and rural, suburban, urban, etc. for population.

MI Splitting polygons
Hi Is there a way of splitting polygons with a line (i.e drawing a line across a polygon to create two polygons?)

MI Re: Splitting Polygons
Hi Georges, I suggest you to try MapLogix, a topological map editing utility for MapInfo. MapLogix lets you use lines or polylines for splitting polygons. You can download the demo version of MapLogix at http://www.korem.com/maplogix.

Not directly, but it's simple enough to: 1. Draw your line. 2. Select it then run Objects - Convert to Regions. MapInfo will add an extra segment to close the region off. 3. Use the Node Add tool to add nodes to this extra segment until it surrounds one of the halves you want. 4. Now use this region object as the splitter object in Objects - Split. Notice you can save a few steps by drawing a region object in the first place.

Does this Data Base generate a three-dimensionnal representation with Mapinfo? Thank for your replies Laurent SCHNELL Laurent, It is possible to create something like 3-D visible towers in Vertical Mapper as individual objects. This works best when used with the following points: x1,y1,z1; x2,y1,z1; x1,y2,z1; x1,y1,z2 (where x1, x2, y1 and y2 are very close together) Use TIN interpolation and set your maximum triangle side length to an appropriately small size. With this, you may create tall, individual tetrahedrons (pyramids with triangular bases). If you have any further questions, please feel free to ask me.

RE: MI Re: Splitting Polygons
This is what I sent Georges earlier. I hope it is helpful for someone. Follow the step below to split a polygon: 1) Make the layer that contains the polygon editable. 2) Select the polygon and choose Set Target from the Objects menu. 3) Draw another polygon that will split the original polygon in the correct place. 4) Select the newly drawn polygon and choose Split from the Objects menu. 5) Select the appropriate field from the box that pops up or select no data and click ok. 6) You now have a split polygon. Delete the second polygon that you used to split the original polygon.

Currently I have to, like every body else :-), right click on the map, and make invisible the layer that I do not want displayed any more, thus making the one below visible. I want to be able to have one mapper window and be able to turn off successive layers, from top to bottom, and show different thematic maps as I present information contained within. I cannot think of any way to do this from within MapInfo Pro apart from having this little toolbar-esque Layer Control. I have searched high and low for a tool that will accomplish this but I cannot find one. I am also open to any suggestions, if you have any, about some other means of accomplishing what I have outlined above. I have entertained the idea of doing this just as a powerpoint presentation but I want the ability to be able to dynamically query the data should the need arise.
