Hello,

I have a problem when I use the get_item method with recordset

for example this source code is Ok:

Code:

string t;
t= "City";
object index = t;
line=rs.Fields.get_Item(ref index).Value.ToString()

but with this another example it doesn't work, it give a crash under MapPoint :

Code:

object index = tab[2].ToString();
line=rs.Fields.get_Item(ref index).Value.ToString()

if I use a variable ( array of string ) then it doesn't work, it work only if the string is hardcoded in source code ( for example t="City" )

do you have a solution for this problem ?

Hi,

I did a test, but not exacly the same as you, but this works without exception:

Code:

            string[] aS = new string[2];
            aS[0] = "My Pushpins";
            o = aS[0];
            rs = mp.ActiveMap.DataSets.get_Item(ref o).QueryShape(s);

Hi,

in fact all is ok now,

my problem was in fact a bad value in some fields ( null values that gives an exception in MapPoint ) ,

with a try/catch the bug is fixed in my source code

Hi,

cool
Glad it works
