MapToolsArchive.zip that does what you have described, only it gets the
xy values from a SqlServer database. It would be easy enough to stream
data in from a file instead. It is in c#.</font>

<br><font size=2 face="Arial">Hi,</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">For some time I have been wondering how one
produces shapefiles from scratch and have found it very difficult to find
relevant information</font>
<br><font size=2 face="Arial">I have numerous files of X,Y data that describe
points, lines and polygons that I wnt to capture as shapefiles.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">Fortunately I found the shapelib pages</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">I downloaded the shapelib tar file and shocked
myself when the make worked.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">I have been able to make some simple shapefiles
by following the instructions, and I am now wondering how I can use my
X,Y files.</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">For example: shpadd testfile.shp 10.0 1.0
20.0 2.0 30.0 3.0, works fine</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">but I want to load an X,Y file containing
1000’s of point into the shapefile. I just cant see how to stream the
coordinates into the ahpadd program</font>
<br><font size=2 face="Arial"> </font>
<br><font size=2 face="Arial">Any advice would be greatly appreciated</font>
<br><font size=2 face="Arial"> </font>
