C++, Windows Forms Application, Reading from a File

I want to read a specific column/line from a file and save those to a variable. So far I was able to read the entire text. But I can't get my code to only read a specific line/column. Here is what I have:

private: System::Void button6_Click_1(System::Object^  sender, System::EventArgs^  e) {
    Stream^ myStream; 
    OpenFileDialog^ openFileDialog1 = gcnew OpenFileDialog; 

    if (openFileDialog1->ShowDialog() == System::Windows::Forms::DialogResult::OK)
    {
        if( (myStream = openFileDialog1->OpenFile()) != nullptr )
        {
            String^ strfilename = openFileDialog1->InitialDirectory + openFileDialog1->FileName;
            String^ Readfile = File::ReadAllText(strfilename);
            myStream->Close();  
        }
    }
}

You need to build your own parser.

I.E: Use StreamReader::ReadLine and than you may you String::Split to split all data into columns.

But you never told us what you define as a column...
