I have drawn squares over a map and am using them to query the number of datapoints and draw a route using those points. I have saved the file and re-use it.
I have noticed that some datapoints near the left hand edge of the square are not selected as being within the square although visually, they clearly are (by 1/4 mile or so) . If I move the shape fractionally and then move it back to where it was and then query the shape again the datapoints ARE found to be within the shape.
Can anyone explain this?

Further investigation shows that the problem is more complicated. It is not just near one border. The area that queryshape is looking at does not exactly match the shape. Sometimes it will return pushpins that are apparently outside the shape as well as sometimes missing those that appear to be within the shape.

The shape moving may be a red herring as this does not always change the results that queryshape returns.

I can confirm that moving a shape does cause the number of records returned by QueryShape to change (and become correct). Here are the key code snippets
objShape.Select()
objRecords = objDataSet.QueryShape(objShape)
lngTotalRecs = 0
objRecords.MoveFirst()
Do While Not objRecords.EOF
lngTotalRecs += 1
objRecords.MoveNext()
Loop
MsgBox("Number of records in shape: " & lngTotalRecs) ' Get e.g. 69 here
' Then I execute this code
SavedLoc = objShape.Location
objShape.Location = Mp.GetLocation(90, 0)
objShape.Location = SavedLoc
and re-run the above
objShape.Select()
objRecords = objDataSet.QueryShape(objShape)
lngTotalRecs = 0
objRecords.MoveFirst()
Do While Not objRecords.EOF
lngTotalRecs += 1
objRecords.MoveNext()
Loop
MsgBox("Number of records in shape: " & lngTotalRecs) ' Get e.g now 74
