Message	Hi, I am trying to use the Geoprocessor -> Analysis Tools -> Statistics Tool from C# and find that the documentation is not helping me. What are the parameters for the Statistics tool ? Does anyone have any samples ? any help would be appreciated. thanks,
	ITable inTbl = clsGDBWorkSpaceManager.openTable("Table1", pws); ITable outTbl = clsGDBWorkSpaceManager.openTable("Table2", pws); IField f1 = inTbl.Fields.get_Field(inTbl.FindField("F1")); IField f2 = inTbl.Fields.get_Field(inTbl.FindField("F2")); Geoprocessor GP = new Geoprocessor(); ESRI.ArcGIS.AnalysisTools.Statistics s = new Statistics(); s.in_table = inTbl; s.out_table = outTbl; s.case_field = f1; s.statistics_fields = "Sum.F2"; GP.Execute(s, null);

Message	I agree that the Geoprocessing documentation leaves something to be desired. Usually, I use the Toolbox to create the type of process I intend to code and get the parameters from the dialog box. In the case of Statistics, this is the line that one test executes: Executing (Statistics_1): Statistics D:\Data\testing\Buja\Export_Output.dbf D:\Data\testing\Buja\Export_Output_Statistics.dbf "HAUL SUM" # I was getting the Sum of the field Haul, so in your case, try s.statistics_fields = "F2 Sum";

Message	Thanks a lot Ken. With your suggestion i was able to get it running. IWorkspace pws = clsGDBWorkSpaceManager.openGDBWorkSpace(clsGDBWorkSpaceManager.GDBType.FileGDB, pth, fileNm, 0); ITable inTbl = clsGDBWorkSpaceManager.openTable("Table1", pws); //ITable outTbl = clsGDBWorkSpaceManager.openTable("Table2", pws); IField f1 = inTbl.Fields.get_Field(inTbl.FindField("F1")); IField f2 = inTbl.Fields.get_Field(inTbl.FindField("F2")); Geoprocessor GP = new Geoprocessor(); ESRI.ArcGIS.AnalysisTools.Statistics s = new Statistics(); s.in_table = @"D:\FDOTwork\QCEW_DataWork\Apps\Data\q1.gdb\Table1"; s.out_table = @"D:\FDOTwork\QCEW_DataWork\Apps\Data\q1.gdb\Table1_Statistics"; s.case_field = "F1"; s.statistics_fields = "F2 SUM;F3 SUM"; GP.Execute(s, null); No where in their(ESRI) poor quality documentation, did they mention the input param "object inoutTableName" is actually a string or the field names should be semi colon separated. How are we supposed to know all these ? anyway thanks for taking the time to help me out. capton.
