    <p>The following code actually does what i want it to do however I'm trying to make it optimal and as im still learning about the BackgroundWorker etc I thought you could give me a few tips. The trouble is I can run the program but because it's quite a long operation (1000's+ lines per text file), it doeant update the progressbar or labels very well only until the program completes. there are 2 progreesbars, one for the number of text files processed and the other for the number of lines read of the text file in the process.</p> <pre><code>namespace myParser { public partial class Form1 : Form { string filePath; string[] files; public Form1() { InitializeComponent(); pbFilesProcessed.Visible = false; pbLinesProcessed.Visible = false; btnParse.Visible = false; lbProcessedFiles.Visible = false; lbProcessedLines.Visible = false; } private void btnOpen_Click(object sender, EventArgs e) { DialogResult result = folderBrowserDialog1.ShowDialog(); if (result == DialogResult.OK) { //counts the number of files in the folder files = Directory.GetFiles(folderBrowserDialog1.SelectedPath); filePath = folderBrowserDialog1.SelectedPath.ToString(); char[] delimiterChars = { '\\' }; string[] filePathParts = filePath.Split(delimiterChars); string folder = filePathParts[4]; tbFolderName.Text = folder; btnParse.Visible = true; } } private void btnParse_Click(object sender, EventArgs e) { btnParse.Visible = false; lbProcessedFiles.Visible = true; pbFilesProcessed.Visible = true; lbProcessedLines.Visible = true; pbLinesProcessed.Visible = true; lbProcessedLines.Text = "Lines: 0 / 0"; int fileCount = 1; foreach (var csvFile in Directory.GetFiles(folderBrowserDialog1.SelectedPath)) { pbFilesProcessed.Maximum = Convert.ToInt32(files.Length.ToString()); string fileName = "Waveforms.csv"; int lineCount = 0; string lines; string newLines; string csvFullFilePath = csvFile.ToString(); string[] filePathSplit = csvFullFilePath.Split('\\'); string pointName = filePathSplit[4].ToString(); string[] pathDirectionSplit = filePathSplit[5].ToString().Split('_'); string[] swingDirectionSplit = pathDirectionSplit[3].Split('.'); string swingDirection = swingDirectionSplit[0]; var numberOfLines = File.ReadLines(csvFile).Count(); using (StreamReader r = new StreamReader(csvFile)) { while ((lines = r.ReadLine()) != null) { pbLinesProcessed.Maximum = Convert.ToInt32(numberOfLines.ToString()); if (lineCount == 0) { lines.Remove(0); lineCount++; } else { newLines = Regex.Replace(lines, ",{2,}", ",").ToString(); File.AppendAllText(@"Simulator\\" + fileName, pointName + "," + swingDirection + "," + newLines + System.Environment.NewLine); pbLinesProcessed.PerformStep(); lbProcessedLines.Text = "Lines: " + lineCount + "/" + Convert.ToInt32(numberOfLines.ToString()); lineCount++; } } r.Close(); } pbFilesProcessed.PerformStep(); lbProcessedFiles.Text = "Files: " + fileCount.ToString() + "/" + files.Length.ToString(); fileCount++; } btnParse.Visible = false; MessageBox.Show("Done"); } } </code></pre> <p>}</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
