Lua - Insert or Delete String in txt file -


Assume that I have a .txt file that has a string I. How can I remove some characters, or both of them Can I include others between? Example: .txt file contains "HelloWald" and I want to insert a comma after "Hello" and there is a place after that. I just know how to write from the beginning and attach a file 

  local file = io.open ("example.txt", "w") file: write ("example") file You have to break it down in different steps .close ()

You have to break it down in different steps.

The following example is "Hello, World" 

  - - Read the file - Local f = io.open ("example.txt", "r") with " Change the "HelloWald") local content = f: read ("* all") f: close () - - edit string - content = string.gsub (content, "hello", "hello,") - - Type it out - local f = io.open ("example.txt", "w") f: write (content) f: close ()

Of course you need to add an error - test, etc.

c# - Showing a SelectedItem's Property -

So I have enabled a rightclick option for my DataGrid. I want to display the only chosen property but it is not behaving like what I would like it to display my name and additional. Public category Paymentinfo {public int PaymentNo {get; Set; } Public string date {get; Set; } Public Double Pay {get; Set; } Public Double Principle {get; Set; } Public Double Interest {get; Set; } Public Double Balance {Received; Set; }} Private Zero MenuItem_OnClick (Object Sender, RoutedEventArgs e) {MessageBox.Show (AmortGrid.SelectedItem.ToString ()); } I'm trying to apply it without using a View Module! If I place a breakpoint where the messagebox and the recipient place it on selected ITEM, then this property will display the payment. A date-payment-principle-interest-balance is the only value that needs payment.
