Creates a .NET DataSet from a single or multiple open FoxPro cursors.
DO wwDotNetBridge
CREATE CURSOR TQuery ( Name c(50), Entered T)
INSERT INTO TQUery VALUES ("Rick",DATETIME())
INSERT INTO TQUery VALUES ("Joe",DATETIME())
INSERT INTO TQUery VALUES ("Markus",DATETIME())
CREATE CURSOR TQuery2 ( Name c(50), Entered T)
INSERT INTO TQUery2 VALUES ("Rick",DATETIME())
INSERT INTO TQUery2 VALUES ("Markus",DATETIME())
LOCAL loBridge as wwDotNetBridge
loBridge = CREATEOBJECT("wwDotNetBridge")
*** Pass the two cursors
loDataSet = loBridge.CursorToDataSet("TQuery,TQuery2")
? loDataSet.DataSetName
*** Tables object is a collection not directly accessible thru COM
? loBridge.GetPropertyEx(loDataSet,"Tables.Count") && 2
? loBridge.GetPropertyEx(loDataSet,'Tables[0].Rows.Count') && 3
? loBridge.GetPropertyEx(loDataSet,'Tables["TQuery2"].Rows.Count') && 2
Manipulation of .NET DataSet objects in VFP is difficult because the internal types are not readily accessible through direct COM interaction - hence the GetPropertyEx calls in the examples above.
The most common scenario for creating DataSets in Fox code is to pass a DataSet to .NET as a parameter.
o.CursorToDataSet(lcAliasList)
Return Value
A .NET DataSet
Parameters
lcAliasList
A comma delimited list of open FoxPro cursors that are to be loaded into the .NET dataset.
