vb.net 2010 - how to get all the words that start with a letter in a datatable? -

-

i'm using visual studio 2010 in spanish. have this:

private sub filter(byval letter char) dim arrayrows() datarow arrayrows = table.select("desc_ art '" + letter + "%'") end sub

so when parameter "letter" "a" rows desc_art starts "a". problem when parameter "letter" "c" don´t words second letter "h". it's program thinks "ch" letter.

how can words who's first letter "c"?

the "letter" parameters declared char, have tried declaring string?
