[MI-L] Hypothetical question regarding MapInfo on Web
Hi all, This is a hypothetical question I've just thought of. Removing licensing and copyright issues from the equation. Is is possible and practical to install MapInfo on a web server and allow a set number of restricted users to access the application (a MapBasic app to be more specific)? I understand MapInfo isn't a particularly appropriate application for web-based access but if you wanted several users to access and run a mapbasic utility (with all the bells and whistles) via the web-is it doable?

[MI-L] Label Anchor
Hi, I am having an issue with labeling symbols I have created. I would like to label the symbols, each with a specific anchor location. My program reads Northing and Easting values from a table, plots the symbols and labels these points with values from a column in the table. I need to assign specific label anchors to each symbol and position the label according to the rotation of the symbol, which is also derived from a column. Here is what I have so far: Update sTable set Obj = CreatePoint(EAls, NAls) sDip = sTable + . + dipCol StrikeAls = sTable + . + strikeCol --- this column holds the symbol rotation values which will determine which anchor I want to use Set Map layer 1 Label Line None Auto on visibility on overlap on with dip position right font makefont(arial, 1, 9, Black, -1) Offset 1 I want to be able to have specific label anchor for each point in the table.

Re: [MI-L] Find Symbol in MI Proviewer 8
Ian, The solution for myself was to change the default find symbol in my MapInfo Professional and then take a copy of my mapinfow.prf file located in (C:\Documents and Settings\[User Name]\Application Data\MapInfo\MapInfo) and copy it to C:\Program Files\MapInfo\ProViewer, or wherever you have proviewer installed. Once you have done that everything should be fine. If you are having problems try deleting the Proviewer folder under the users Application Data folder. Example of mine. C:\Documents and Settings\lbritt\Application Data\MapInfo\MapInfo\Proviewer. The next time the users, uses ProViewer it will reinstall the application data folder part and everything should be OK. Give it a try and let me know how things work out. I received this answer from Moshe Binyamin, who is the Senior Product Manager for MapInfo in the US. Leith, The quick answer I got is that the MAPINFOW.PRF file that you can place under one of two locations: 1. Under you local user settings i.e.: C:\Documents and Settings\[USER NAME]\Application Data\MapInfo\MapInfo OR 2. Under the application directory i.e. D:\Pro80\app\ Note: if both exist, the one in you local user settings will be found first and that will be the one we use. If you remove that one we will use the one in the application directory. MAPINFOW.PRF file has the default style setting in it and we now read it to set the default style for the application. Please let me know if this works for you. Leith C.

I couldn’t see any reply to it but was wondering whether you had found a solution to it? Like you I have users who would simply like a different default symbol to the grey star. In a previous version of ProViewer, once it was set it at least stopped the same, but as you found it now reverts back to the default every time you use the find. http://lists.directionsmag.com/discussion/read.php?f=7i=47521t=47521 Look forward to hearing from you.

RE: [MI-L] Hypothetical question regarding MapInfo on Web
A very interesting question and one that is timely. In a few days MapInfo will host its annual User/Developers Conference in Phoenix. If you follow the issues of MapInfo technology evolution you may already be aware that MapXtream is the critical technology core for all future MapInfo technology and desktop products via its .NET design. We do not have this yet in Pro 8.0 other than some serious progression in design coordination in the workspace between MapXtream and Pro designs. There is other stuff as well but the workspace seems to me the critical step of progression - getting the common man ready for a rather large shift IMHO. The re-engining of MapInfo Pro with MapXtream.NET is rumored to be included in Pro 8.5. This technology shift to .NET from .COM and MapBasic, and that is what it is, will be disruptive. Those that developed on MapX and MapXtream Windows (legacy and preambles to MapXtream.NET 5.0) will not fare as neatly tough. Importantly MapInfo has made some limited promises that they will do their very best to not only release the developer and the Pro platform from the limitations of old design Microsoft methods for new .NET opportunity but they intend to allow an elegant extension of the MapBasic legacy code sets into the new design - backward compatibility. This is rather neat and if they pull this off, well they will have avoided a huge depreciation of partner and client MapBasic investments. So I guess the answer is it looks like MapInfo Pro's future connection to the internet is just around the corner? Any takers on extending insight and rumorology of the likely Pro future? Oh and buy the way, I have had some really great results of merging my map-analysis and workspaces on to Google Earth.

RE: [MI-L] Hypothetical question regarding MapInfo on Web
Hi, I'm pretty sure that MapInfo 8.5 will not be the version that moves MapInfo to the .NET platform. This move to .NET is based on the project known as Grande. As far using MapInfo Pro on the Net, I'm sure that this could be done. But you would need to combine the internet development tool with MapInfo using MapBasic or integrated mapping. So I don't think that you'll actual get the MapInfo Pro user interface presented in your browser. You will more likely use MapInfo Pro as a backend service to create pictures to show in the browser. A different approach would be to use MapInfo Pro in a Citrix enviroment. This enviroment can be accessed thru a browser, that will present the user with a desktop like user interface. Quite a very usefull solution, but this will often require some extra thick client to be installed on the client computer. Both these approached will of course be pretty limited when you read thru the license of use. This strictly forbid the use of MapInfo Pro on a web server (not sure these are the exact words, but definitely the meaning). I'm going to the conference this year.

[MI-L] Angle Measurement in MapBasic/MapInfo
Given a set of points (specifically, a hurricane track) I am trying to select one point in sequence, then the next point in sequence, extract the angle and distance between the two, and then create intermediate points using the Offset function, the angle, and a fractional portion of the distance. Im using ANGL = Asin(Distance(F_XX2,F_YY2,F_XX2,F_YY1,mi)/Distance(F_XX1,F_YY1,F_XX2,F_YY2,mi))* RAD_2_DEG to measure the angle, where F_ANGL is the angle, F_XX2 is the CentroidX of the second point, F_YY2 is the CentroidY of the second point, F_XX1 is the CentroidX of the first point, and F_YY1 is the CentroidY of the first point. All variables (in this instance) are float values, To make a long story short, my program ran perfectly on what set of data, creating the intermediate points perfectly. On the other hand, it didnt work on a second set of data, even though the projections (between the first and second set) were the same. Rather than neatly falling between the first and second points, as in the first dataset, the intermediate points were skewed off in the another direction. Anyone have any ideas what is happening here? Thanks much, Mike Jenne ___ MapInfo-L mailing list MapInfo-L@lists.directionsmag.com http://www.directionsmag.com/mailman/listinfo/mapinfo-l
[MI-L] [Spam] Legal Aspects in Buying code
Dear Friends; I'm about to embark into developing an app for a client of mine in MapX; I will be asked to do things that are exactly or very similar to stuff that is already made by several of you; what would be the legal aspects regarding me buying code from apps (full or partial) that you have developed? -Would it be more expensive at the end (time included) than writing it myself?

RE: [MI-L] Angle Measurement in MapBasic/MapInfo
1. Where did you set your projection? In the MapBasic window (i.e. using Run Command) or directly in your application (in line Set Coordsys statement)? I've been burned by this more than once and now always do both. 2. There's no need to calculate angles for your application. Trig functions are approximations and introduce errors. Instead, use ordinary analytic geometry to get X and Y coordinates for points between nodes. 3. Is the projection appropriate for these calculations?. With a conformal projection you can use ordinary Cartesian geometry rather than spherical geometry. Add a Bounds clause to your Coordsys clause to get maximum coordinate granularity. 4. Arcsin has accuracy issues (small changes arising from coordinate granularity result in large changes in the result) in parts of its domain. To calculate an azimuth ase Atan2 or a function that simulates it. HTH Spencer PS Hope the code below helps. Don't blame me if it doesn't compile.

RE: [MI-L] Hypothetical question regarding MapInfo on Web
Ben, We played with this in 1999, and had a system where you could enter data through a web interface, run an airport noise model, then fire up mapinfo, have it generate a map of the result as an image, and hand that back on the web. I think it was done with a Active X wrapper around pro. It was a total hack, and never went anywhere as the licencing restricted it from happening, even if we had comtemplated trying to make it work commercially. As I remember there were even send key commands in it. My new programmer was just showing off. There will be problems getting a native program running over the web as the web interface generally tries to prevent you from doing that. You may be better off with some sort of VPN access. My expertise is limited in that field. Depending on what you are doing in Mapbasic, there may be alternatives using webbased map delivery software for the interface, and doing the processing in something like Oracle, or even a Mapinfo/ Mapbasic backend that uses the data to generate a result that can be dislayed.
