What is the best way in Maptitude 5.0 to convert all of the null integer values in a table to 0? I seem to remember being able to do that modifying the fields...
Rob, There is a function called "null to zero" which will do the job. It doesn't appear in the function list of the formula builder, but you can still access...
I am trying to use the Maptitude COM object in Visual Basic 6. I followed the example, which runs fine, but can not figure out how to successfully call the...
It sounds like a projection error. You may need to define the projection type in array_options. Look at your input CSV file: is there any coordinate conversion...
Hi Group: A few pointers: The issues demonstrated in the sample code provided by the user are: 1. Options array: ''' ===================== ''' ORIGINAL '''...
Thank you. It was the Options array that was causing me problems. The only thing I'll note is that in your correction you have Dim Options as Object and it...
Hello, I was wondering if anyone knows of a way to apply a theme to (and only to) a selection, without exporting to a separate layer and/or changing the...
This worked for me some time ago 1) Add a field to the dataview of your layer called THEMEFILED (or any name that makes sense to you) 1) Display your...
Hi Armando -- Thanks for your insight. While I had a little trouble implementing your steps verbatim, your method did spark some ideas on how to apply a theme...
Hi All, Following on the discussion of Themes, I've a question. Given a layer with several lines in it, which intersect in some areas and almost overlap in...
Hey Josh, Not sure I understand 100% what you are trying to do, so I haven't been able to test this idea. But here goes anyhow: 1) Create your color theme as...
Is there a way to have multiple color themes on a layer based on 2 different columns? I have a layer with data in 2 columns and I want to have a theme for...
Without more specifics, it's hard to tell exactly what you are trying to do... but why not create a 3rd field that represents the interaction of the two fields...
Fellow Maptituders, I have uploaded a new utility to Directions Magazine called StatBridge. It was inspired by Dick Hoskins' comment in Message #3844 about...
I am trying to create a Maptitude Map using the .NET functionality. I seem to be able to create the map and do some basic settings(no errors, haven't been...
Can someone point me to the proper syntax for geocoding through a .NET application? I have the following code and the "Standardize" function returns proper...
I am trying to do the following and wonder if someone has a solution. I need to overlay tracts over streets and I want to calculate strength length in order to...
This may work for one tract: 1) Use select by condition to select all streets INSIDE the tract . This gives you all streets segments that do not intersect...
Thanks. That sounds like it will work.. Mike Michael E. Cline Research Associate Institute for Demographic & Socioeconomic Research The University of Texas at...
Fellow Maptituders, Happy new year! I have uploaded a new utility to the Directions Magazine website. It is free and open source (GPL v3). Leader Lines is an...
Very very nice. I'm currently using Leader Lines as well as your Layout Tools and was thus inspired to build a custom disclaimer/metadata toolbox specific to...
Hi Group: I just wanted to let you know that the 4th Quarter 2008 ZIP Codes have been released. Please see the following page for additional information,...
Could someone tell me how to do the following or if it is not possible: I have a layer with oddly shaped features. I would like to generate a new layer with...
Shaung, One way is to get the centroids of your irregular polygons (by exporting the centroids and then adding the new point layer). Then for each polygon find...
The GetMinimumSpanningCircle() command should get you what you need. It returns a circle "compound variable"-- you can extract the center coordinate and radius...
I haven't used GISDK in a long while - particularly since I installed 5.0. Now I need to rund some macros and I am not able to run the GISDK. I get the...
Mike, I'm not running Vista, and I have never seen this *specific* error, but it sounds like a permissions issue. Maptitude creates a file with an ".err"...
THanks. That sounds about right. Although I am not sure why I don't have rights in some of my directories. I did install Maptitude on my desktop computer...
