array ^Value = gcnew array(0);
array ^MatchingRows= gcnew array(0);
SqlClient::SqlConnection ^SqlConnection1 = gcnew SqlClient::SqlConnection();
SqlConnection1->ConnectionString = DataSourceString + DatabaseConnectionString;
SqlConnection1->Open();
SqlClient::SqlCommand ^SqlCommand1;
SqlCommand1 = gcnew SqlClient::SqlCommand();
SqlCommand1->Connection = SqlConnection1;
SqlCommand1->CommandType = CommandType::Text;
SqlCommand1->CommandText = "SELECT TagScore, COUNT(TagScore) FROM tblTagEvents WHERE SomeColumnName='Active' GROUP BY TagScore"
SqlClient::SqlDataReader ^reader1 = SqlCommand1->ExecuteReader();
while (reader1->Read())
{
Array::Resize(Value, Value->Length + 1);
Array::Resize(MatchingRows, MatchingRows->Length + 1);
Value[(Value->Length - 1)] = Convert::ToInt32(reader1[0]);
MatchingRows[(MatchingRows->Length - 1)] = Convert::ToInt32(reader1[1]);
}
