Dispose would also close it. Closing it will not dispose it, but will return the connection to the pool. This will not work for all classes in the same way though.

Issue using the StreamWritter Class

I have a project that i have to create and write to a text file using the StreamWritter class. i create the file just fine and after playing with it a little got the text to enter into the file correctly but i cant add more text to the file after the inital line or it just truncates whats already inside of it, i want the text inside to add each time the button is clicked even after the program closes and i reopen it. here is my code so far

using System.IO;

namespace SWardVideoSalesApplication
{
    public partial class MainSalesForm : Form
    {
        public MainSalesForm()
        {
            InitializeComponent();
        }

        #region Variables
        //TEST VARIABLES
        StreamWriter testFile = File.CreateText("TestFile2.txt");

        #endregion

private void summaryButton_Click(object sender, EventArgs e)
{
    //Displays the summary text file in a label for the user to read
    //First a simple test of the file writting
    bool Flag = true;

    testFile = File.
    if (Flag)
    {
        testFile.WriteLine("This is a test {0}", todayDate.ToString());
        testFile.Close();
    }
    else
    {
        MessageBox.Show("ERROR");
    }

Hi,
The answer to your question is to set the stream writer to append mode.
Try this:

string _fileName  = "TestFile2.txt";
private void summaryButton_Click(object sender, EventArgs e)
{
    //Displays the summary text file in a label for the user to read
    //First a simple test of the file writting
    bool Flag = true;
    if (Flag)
    {
        string content = string.Format("This is a test {0}", todayDate.ToString());
        writeToFile(_fileName, content);
    }
    else
    {
        MessageBox.Show("ERROR");
    }
 
}

private void writeToFile(string fileName, string content)
{
    FileInfo fi = new FileInfo(fileName);

    // Check that the file exists first
    if (!fi.Exists)
    {
        MessageBox.Show("file doesn't exists!");
        return;
    }
    else
    {
        using (StreamWriter sw = new StreamWriter(fileName, true, System.Text.Encoding.Default))
        {
            sw.Write(content);
        }
    }
}

Hope this helps.

The reason the code is failing is because the following is happening:

You create the TestFile2.txt the first MainSalesForm is instantiated. Subsequent instantitations of MainSalesForm will overwrite the file effectively blanking it. (try prepenging the DateTime.Now.Ticks to the filename to see when the file is actually being created/overwritten).
On button click, you write to the file and close the stream so the file can no longer be written to. If the CreateFile is executed later (say the form is closed and reopened) it will overwrite what has been written.

I suggest the following code:

private void summaryButton_Click(object sender, EventArgs e)
{
     WriteToFile(string.Format("This is a test {0}", todayDate.ToString()); 
}


private void WriteToFile(string fileName, string content)
{
    FileInfo fi = new FileInfo(fileName);
    // Check that the file exists first
    if (!fi.Exists)
    {
        using(StreamWriter testFile = File.CreateText(fileName)
        {
            sw.Write(content);
        }
    }
    else
    {
        using (StreamWriter sw = new StreamWriter(fileName, true))
        {
            sw.Write(content);
        }
    }
}

Once the button is pressed the file will be created (if it does not exist) or will be appeneded to with the string passed to the method. Note that the file is not locked between clicks (so you can open it for reading and writing). This may not be the desired behaviour, if not the code will be unsuitable. The code I have provided may not compile (I haven't tested it) and could be tidied a little but it should get you on track.

Are you trying to automatically fill and submit a login form?

If so, you can use a WebBrowser control to do this:

new WebBrowser().Navigate(
    url,
    "_blank",
    Encoding.Default.GetBytes(
        "username=" + username +
        "&userpass=" + userpass),
    "Content-Type: application/x-www-form-urlencoded");

where url, username and userpass are string variables containing the data. Obviously change the names of the fields to what the names are of the input fields of the original HTML form, and add other fields as required.

Re: Copy username from text file to website

DaveyM695-Mar-13 3:08

First of all, you need the correct URL which is https://www.facebook.com/login.php
Then you need the correct names for the fields which are email and pass

I got all this information by looking at the HTML source for the Facebook login page.

So the code is:

string facebookUrl = "https://www.facebook.com/login.php";
string facebookEmail = "user@domain.com";
string facebookPassword = "userpassword";
new WebBrowser().Navigate(facebookUrl, "_blank", Encoding.Default.GetBytes(
    "email=" + facebookEmail +
    "&pass=" + facebookPassword), "Content-Type: application/x-www-form-urlencoded");

Change the value of facebookEmail and facebookPassword to your login details and it should work.

Create a polygon that represents each tooth. Do a test to see if the click point is inside the polygon. If true, colour the polygon.

Another method is to allow the user to point to and click at the centre of each tooth.
Save the co-ordinates in a List of Tooth class(you will need to define the Tooth class).
On clicking a dialogue box the application can then ask which tooth number has been selected.

Then when it comes to identifying teeth:
As teeth as fairly round(well more oval really) in shape you can detect if the user clicks with the orbit of the declared centre of each tooth and respond accordingly.

I've asked maybe to broad of a question before. So I have created a very simple application. My Word document has 1 chart in it.

In a nutshell, where is what happens:
1. Word Document is opened.
2. Find the number of Charts in the document.
3. Loop through the inline shapes
4. Check to see if they are Charts.

So as I said, nothing fancy.

private void Form1_Load(object sender, EventArgs e)
        {            
            Document oReportDoc = new Document();
            Microsoft.Office.Interop.Word.Application oWord = new Microsoft.Office.Interop.Word.Application();
            oReportDoc = oWord.Documents.Open(@"C:\ChartTest.docx", ReadOnly: false);
            label2.Text = oReportDoc.InlineShapes.Count.ToString();
            int j = 1;
            foreach (Microsoft.Office.Interop.Word.InlineShape wshape in oReportDoc.InlineShapes)
            {
                try
                {
                    if (wshape.OLEFormat.ProgID.Equals("Excel.Sheet.8"))
                    {
                        if (wshape.HasChart == Microsoft.Office.Core.MsoTriState.msoTrue)
                        {
                            wshape.OLEFormat.Open();
                            Microsoft.Office.Interop.Excel.Workbook xlWorkBook = wshape.OLEFormat.Object;

                            if (xlWorkBook != null)
                            {
                                xlWorkBook.ActiveChart.HasTitle = true;
                                xlWorkBook.ActiveChart.ChartTitle.Text = "test" + j.ToString() + "!";
                                j++;
                            }
                        }
                    }
                }
                catch (Exception ex)
                {
                    richTextBox1.Text = ex.Message;
                }
            }
        }

So it appears that, when debugging the code, that the OLEFormat property is Null, which I assume is causing the exception to fire off.

Can anyone tell me what is happening here and why the OLEFormat is null? And how to get around this issue?

Very frustrating.

Thanks,
Jeff

You should check this with your debugger, and provide the exact content of wshape and the exception at the point of error.

Richard is exactly right - put a breakpoint on the first line in the method, and single step through the code. At each point, look at the appropriate variables and see which of them is wrong. You can then try to work back to where that wrong value came from, or at least give us better information on the actual problem.

Normally, an exception holds a good level of detail - including the line number that the error occurred on. This can help - but only if you tell us what the error message is exactly, and which line it appears on!

Change this line

private sealed class struc

internal sealed class struc

The error is because you defined the the class struc as private and using it outside through internal at this line

internal static struc[] arrStruc = new struc[]
