I am having trouble running some ArcObjects C# code that calls create random points. I would not be doing this in ArcObjects, but I am suffering with the same issue using Arcpy as seen here: http://forums.arcgis.com/threads/12782-Python-scripting-and-creating-random-points?p=85866&viewfull=1#post85866

Any help as to the cause of this error would be greatly appreciated (Indeed, an official confirmation that create random points is bugged would also be appreciated).

code excerpt:

//ESRI License Initializer generated code.
new esriLicenseProductCode[] { 
esriLicenseProductCode.esriLicenseProductCodeArcInfo }, 
new esriLicenseExtensionCode[] { esriLicenseExtensionCode.esriLicenseExtensionCodeSpatialAnalyst });
//ESRI License Initializer generated code.

//For some reason the license thing above doesn't always do the job so this is here
IAoInitialize ao = new AoInitialize();

Geoprocessor gp = new Geoprocessor();
gp.OverwriteOutput = true;
gp.LogHistory = true;

//Input parameters
string constrainingFeatures = "lineRoute";
string outFeatures = "test";
string workspace = "\\\\\\output\\Routes.gdb";

//Open workspace
IWorkspaceFactory workspaceFactory = new FileGDBWorkspaceFactoryClass();
IWorkspace gdb;
    gdb = workspaceFactory.OpenFromFile(workspace, 0);
    Console.WriteLine("Unable to open geodatabase");
IFeatureWorkspace fws = (IFeatureWorkspace)gdb;

//Get constraining feature class
IFeatureClass fc = fws.OpenFeatureClass(constrainingFeatures);

//Create random points - DOES NOT WORK WITH A PATH TO WORKSPACE OR THE IFeatureWorkspace
//CreateRandomPoints crp = new CreateRandomPoints(fws, outFeatures);
CreateRandomPoints crp = new CreateRandomPoints(workspace, outFeatures);
crp.number_of_points_or_field = "2000";
crp.minimum_allowed_distance = "1 Meter";

//DOES NOT WORK WITH A PATH TO cfc OR the IFeatureClass
//crp.constraining_feature_class = fc;
crp.constraining_feature_class = workspace + "\\" + constrainingFeatures;

//this out_feature_class does not seem to make a difference
crp.out_feature_class = workspace + "\\" + outFeatures;

    gp.Execute(crp, null);

Here is the log:

    Is this a standalone exe? If so are you initializing the license? Commented Mar 16, 2011 at 20:06
  • Eddie, are you using 10.0 sp1? I found another bug (crashes when creating large numbers of random points) that was included in sp1. It's not listed in the issues fixed for the patch because it came in as a crash dump report. Um, never mind, as I found NIM061594 (not fixed yet) which appears to be a duplicate of nim064833.

  • Hi, I am using 10.0 sp1. I am also initializing the license (I added the code above).

In early February, ESRI acknowledged the python part of your question as a bug when I asked for support: [#NIM064833 ArcPy.CreateRandomPoints_management crashes ArcMap when run as a script tool]

I suspect that the same bug is precluding using the tool from ArcObjects.

    Wouldn't it be nice if ESRI would use a public bug tracker, so we wouldn't have to individually reproduce all this head banging. Commented Mar 16, 2011 at 20:04

    If you're logged into the Esri website, you can search for bugs. You get the headline and workaround (if any known) only. Admittedly, I had trouble turning up NIM064833 because I didn't search for CreateRandomPoints_management ("Create random points" nor "createrandompoints" didn't turn it up). If you have the nimbus number, you can search those (nim064833). std disclaimer: I work for Esri.

  • @mkennedy, Thanks. I'd searched before, but never found it. Here is more info on Bugs Online. Commented Mar 16, 2011 at 21:15
  • Thanks, I always have trouble finding out if bugs have been confirmed (I usually just post here or on the esri forums and hope for some confirmation).
