I am using the StreamWriter to create a log file for my application. However I do not see a method on how to clear the file (make the file blank again). Also before I clear the file I want to rename it so that I can have multiple log files, a new one produced everytime the application runs.

I am using TextFieldParser to read a .txt file and create a DataTable I then filter the table and create 4 new tables I then bind those tables to BindingSources Then Bind ComboBoxs to the BindingSource Then bind TextBoxes to BindingSource I like the user to be able to Open a new file without having to close the program So upon opening a new file I have a sub routine that clears the tables the rows and the columns of each table as well the DataBindings to each control The problem is once I do the Text Binding as such
Me.list1_MLStxt.DataBindings.Add("Text", Subject_Values.BindingSource1, Form10.mls_txt.Text)
Then when I open a new file I get an error message conversion from string"""" to type double is not valid.If I never perform the binding I can open and reopen different files without a problem. So this is causing me to think that the problem is with the way I am clear something? But I am obviously not sureIs there something I am missing to clear everything properly in order to open and read and bind a new file?

View 1 RepliesIn my winform program (in vb.net) I wrote:

[Code].....
But when I run the program, Clear() cleared both dt and dttemp! Why? Aren't dt and dttemp supposed to be two distinct instances of DataTable?
(I finally found a solution - dttemp = dt.Copy() instead of dttemp = dt. But I still can't see why Copy() was necessary in this case.
