| DisplayDataMap in Delphi 7 I try to import a dataset from a CSV file and display it at shaded area. I successfully implemented the ImportData() call with Delphi. The data ist displayed as PushPins if I stop after call ImportData(). Now I work on the DisplayDataMap() call (in VB I did it with the wanted result)., but I get always an error message: "Wrong Parameter" or " The CVS files looks like "Data,Street,ZIP,City,Name" and the code is: var fields: Variant; // OleVariant; objDataSet: DataSet; err,cnt,i: integer; s,t: string; objRecordset: RecordSet; idx: OleVariant; objField: OleVariant; colExpr: OleVariant; objDataMap: DataMap; lColorRange: longint; ArrayOfCustomValues: OleVariant; ArrayOfCustomNames: OleVariant; DivideByField: OleVariant; ArrayOfDataFieldLabels: OleVariant; ArrayOfPushpinSymbols: OleVariant; begin ..... objDataMap:= objDataSet.DisplayDataMap(geoDataMapTypeShadedArea , // DataMapType objField, // DataField geoShowByZoomLevel, // ShowDataBy geoCombineByAdd, // CombineDataBy geoRangeTypeContinuousLog, // DataRangeType geoRangeOrderDefault, // DataRangeOrder 0, //geoColorSchemeDefault, // ColorScheme 1, // DataRangeCount ArrayOfCustomValues, ArrayOfCustomNames, DivideByField, ArrayOfDataFieldLabels, ArrayOfPushpinSymbols); Any hint, what the right parameter is? THANKS Steffen |
