I found that I was using an old version of GeoProc last night. Any idea what's the difference with v1.1 to v4.7? I am a bit concerned my work won't work on the new geoproc...

Hi Dominc02,
I am not familiar with v1.1, nor in detail with v4.7. However, you may find the following helpful:
New MapWindow4 web site (under construction) at [mapwindow.codeplex.com]
Start of MapWinGeoproc documentation pages at [mapwindow4.codeplex.com]
You can create your own more complete documentation using [mapwindow4.codeplex.com]
All you need is DocBlogger and the file MapWinGeoProc.xml from SVN for MapWindow4Dev/WeeklyBuilds/LatestPatches.
Hope this helps you a little bit further.
Gerd

Thanks Gerd... unfortunately the site is incomplete. I read another solution somewhere there about someone taking the C# code of geoprocs available and used a converter to convert it to .net. The possibility that I might code a function w/o the geoproc struck me so I went and did it.

In anycase, thanks again for the help.

BTW, looking at the geoproc code in VB.NET makes me dizzy...

Edit: On second thought please give me a clue on how to clip polylines without geoprocs.

Dominic,
the two of us are an off pair. I struggle still with the basics of C# and you seem to do so with VB.net.
For what it's worth, have a look at [mapwindow4.codeplex.com]
and also at [svn.mapwindow.org] for the source code.
Note this is a Tortoise SVN repository and should be checked out using [tortoisesvn.net]
Good luck, Gerd

Does C++ and C# have the same codes?

The version numbers of mwGeoProc weren't updated correctly in the past. That is way you've got a huge step between v1.1 and v4.7.
v1.1 was shipped with MapWindow v4.6

Now the version numbers of the important libraries are consistent with the version numbers of MW.

BTW. We're now on v4.8RC1 I would suggest using that version instead of v4.7 which is over a year old. You might also consider using the latest beta version. That version is even newer than v4.8RC1. You can get it using [tinyurl.com]

mwGeoProc is written in C#, so you should not have any trouble reading the code.

If you want to clip polygons you can also look at the methods in the ActiveX. In MapWinGIS.Utils are some related methods and the shapefile object also has some geoprocessing methods.

Here are some sample scripts we use for testing: [svn.mapwindow.org] Those scripts might help as well.

Thanks, I'll be sure to try the new one. So the new one won't conflict with the codes I have worked on with mwgeoproc 1.1? That's good news...
