Extract data from Excel into binary text file

In an Excel document (.xlsx, for .xls use

connStr

as the connection string), name one worksheet "Questions" and another "Answers" (no quotes in both cases). All columns are in Excel General format; the allowable format is noted in parentheses: Questions worksheet: QuestionID (Number), QuestionText (Text) Answers worksheet: AnswerID (Number), AnswerText (Text), QuestionID (Number), Correct (Text, but the only acceptable values are TRUE and FALSE).

var fileName = string.Format("{0}\\dbase.xlsx", Directory.GetCurrentDirectory());
var connStr = string.Format(
  "Provider=Microsoft.Jet.OLEDB.4.0; data source={0}; Extended Properties=Excel 8.0;", fileName);
var connectionString = string.Format(
  "Provider=Microsoft.ACE.OLEDB.12.0;Data Source={0};Extended Properties=Excel 12.0;", fileName);
var adapter1 = new OleDbDataAdapter("SELECT * FROM [Questions$]", connectionString);
var adapter2 = new OleDbDataAdapter("SELECT * FROM [Answers$]", connectionString);

var ds = new DataSet();

adapter1.Fill(ds, "Questions");
adapter2.Fill(ds, "Answers");

var answersTable = ds.Tables["Answers"].AsEnumerable();
var questionsTable = ds.Tables["Questions"].AsEnumerable();

List answers = answersTable.Where(
  x => x.Field("AnswerID") > 0.0).Select(x =>
     new TestQuestionAnswer
     {
         AnswerID = Convert.ToInt32(x.Field("AnswerID")),
         AnswerText = x.Field("AnswerText"),
         AnswerCorrect = x.Field("Correct"),
         QuestionID = Convert.ToInt32(x.Field("QuestionID"))
     }).ToList();

List questions = questionsTable.Where(
  x => x.Field("QuestionID") > 0.0).Select(x =>
    new TestQuestion
    {
        QuestionID = Convert.ToInt32(x.Field("QuestionID")),
        QuestionText = x.Field("QuestionText")
    }).ToList();


foreach (TestQuestion tq in questions)
{
    List a = answers.Where(x => x.QuestionID == tq.QuestionID).ToList();
    tq.Answers = a;
}

using (FileStream fs = new FileStream("data.dat", FileMode.Create))
{
    using (var writer = new BinaryWriter(fs))
    {
        writer.WriteList(questions);
    }
}

Adjust the label text size of radiobutton or checkbox

txtQuestion.Text = "Question text";
int answerBreak = panel1.Height / NUMBEROFANSWERS;
int runningHeightTotal = 0;

panel1.Controls.Clear();

for (int i = 0; i < NUMBEROFANSWERS; i++)
{

  Font stringFont = new System.Drawing.Font(
    SystemFonts.DefaultFont.ToString(), 12, System.Drawing.FontStyle.Regular);

  //Gotcha 1: MeasureText does not produce accurate results
  Size textSize = TextRenderer.MeasureText(
    testQuestions[currentlyTestedQuestionID].Answers[i].AnswerText, stringFont);


  RadioButton rb = new RadioButton();
  rb.Tag = testQuestions[currentlyTestedQuestionID].Answers[i].AnswerID;

  //shift down if the previous answer took too much room
  rb.Location = new System.Drawing.Point(5, 
    (i * answerBreak >= runningHeightTotal ? i * answerBreak : runningHeightTotal + 5));
  rb.Text = testQuestions[currentlyTestedQuestionID].Answers[i].AnswerText;
  rb.Size = new System.Drawing.Size(textSize.Width, textSize.Height);
  rb.Font = stringFont;

  using (Graphics g = rb.CreateGraphics())
  {
    bool height = false;
    int linesNumber = 1;
    //so the text size is measured using the Graphics object
    Size s = g.MeasureString(rb.Text, rb.Font).ToSize();
    if (rb.Size.Height <= s.Height)
      height = true;

    if (s.Width > PANEL1WIDTH)
    {
      linesNumber = s.Width / 750;
      if (s.Width % PANEL1WIDTH > 0)
        linesNumber += 1;
    }

    rb.Size = new Size(PANEL1WIDTH, 
      height ? (s.Height + 5) * linesNumber : rb.Size.Height * linesNumber);
  }

  runningHeightTotal += rb.Height;

  panel1.Controls.Add(rb);
}

If checkbox's size needs to be adjusted, declare rb as a CheckBox, and everything will work just as well.

Get Stream for a BinaryReader for a file embedded in exe

public Stream GetDataFileStream(string resourceName)
  {
    foreach (string currentResource in System.Reflection.Assembly.
        GetExecutingAssembly().GetManifestResourceNames())
      if (currentResource.LastIndexOf(resourceName) != -1)
        {
          return System.Reflection.Assembly.GetExecutingAssembly().
            GetManifestResourceStream(currentResource);
        }

        throw new Exception("Resource not found : " + resourceName);
  }


//Then call this code:

using (BinaryReader reader = new BinaryReader(GetDataFileStream("data.dat")))
  {
    yourDataContainter = reader.ReadOrWhatever();
  }
