You need to retrieve more information into VB to make this work OR pass more
to MapInfo - the statement Selectioninfo(Sel_info_TableName) will have no
meaning for VB.
What you are doing is a ssembling strings in VB and passing them to MapInfo
for execution - so you need the correct MapBasic syntax.
(Selectioninfo is a MapBasic statement and Sel_info_TableName is a MapBasic
constant).
Try
mapinfo.do " Dim K as string "
'if you have MapBasic.BAS in your project you can do this -
mapinfo.do " k = Selectioninfo(" & Sel_info_TableName & ")"
'Otherwise
mapinfo.do " k = Selectioninfo(1)"
'To retrieve the result
myval = mapinfo.eval("k")
'For housekeeping then remove your variable in MapInfo
mapinfo.do " UnDim K"
You CAN do all this in a single statement
eg
myval = mapinfo.eval("Selectioninfo(1)")
