I have a print form which does the printing jobs. When I close the print form without printing I click Close button
Close button has
private void Close_Click(object sender, EventArgs e)
{
PublicVariables.PrintData = -1;
PublicVariables.PrintStat = false;
ppc.Document = null;
ppc.Dispose();
streamToRead.Close();
this.Hide();
}
But each time I create a text file to print I delete the old.
Delete method :
public static bool DeleteData()
{
bool result=true;
string pattern = "data??.txt";
string appPath = Path.GetDirectoryName(Application.ExecutablePath);
var matches = Directory.GetFiles(appPath, pattern);
foreach (string file in Directory.GetFiles(appPath).Intersect(matches))
{
try
{
File.Delete(file);
result =true;
}
catch (IOException e1)
{
MessageBox.Show(e1.ToString());
return false;
}
}
return result;
}
But if an IOException occurs can't delete any file. However form load of all threads I have DeleteData() and this deletes without problem the text data.
Is there a way to delete this text file within in the thread where it's created ?
For those who will advise me to make an hidden form which will delete data. I did it I got always an IOexception error. After few IOexception errors all data??.txt files are erased but it happens randomly.
Here below two procedures which create data??.txt

Here is the CreateDataFile(string fName) and GetNewfName(string oldName) procedures link:
