Summary and focused fixes based on the thread (error: "Access to the path 'C:\mandis.ini' is denied") — was correct that writing to the root of C: is often blocked for standard users, and correctly pointed out the literal-string/backslash confusion. There is also a logic/flow issue in the dialog handling: creating or re-showing a SaveFileDialog inside its FileOk handler will break the expected flow. The setDirty() code also overwrites its own checks instead of combining them.

Prefer writing to a user-writable location (AppData or Documents) or use the filename returned by SaveFileDialog; always check the dialog result and handle exceptions. Example patterns:

Write to an app data folder (safe default):

var folder = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.LocalApplicationData), "MyAppName");
Directory.CreateDirectory(folder);
var path = Path.Combine(folder, "mandis.ini");
File.WriteAllText(path, sb.ToString());

Use the SaveFileDialog result (do not instantiate/show a new dialog inside FileOk):

if (saveFileDialog1.ShowDialog() == DialogResult.OK)
{
    try
    {
        File.WriteAllText(saveFileDialog1.FileName, sb.ToString());
    }
    catch (UnauthorizedAccessException ex)
    {
        MessageBox.Show("Cannot write file: " + ex.Message);
    }
}

Fix the UI-enable logic by combining conditions into one assignment instead of three overwrites:

btnOk.Enabled = chkLoggin.Checked && txtFilePath.Text.Length > 0 && txtNumOfThreads.Text.Length > 0;

Notes and troubleshooting: running as Administrator will confirm a permissions problem but is not a deployment fix. Also check file attributes (read-only), locks by other processes, and antivirus. Tying the above to the thread: follow 's advice on string literals, accept 's permissions point, and remove the extra SaveFileDialog usage in the FileOk handler to keep the flow predictable.

Is there some problem with the code? Or is it merely for imformative purposes?

So where exactly are you have problems? are you getting exception? Or is the data not displaying in your file? Are you limited to a certain type of file?

Sorry for all the question but it makes it alot easier to help you.

'@' means the string following is literal. Either remove the '@' or remove one of the '\'.

programe that creates,save, open file and writes user's input to a file
