FileWrite and delete char

Hi everybody, new here.

I'm messing around with AutoIT since a few days. 

I'm actually doing some experiment on my computer, and want to do a simple textbox on my desk, and when I type some things like "chrome" then click OK or input Enter, it launch chrome.exe

Anyway, I'm storing a historic of my inputs in a txt file. And if I push my BackSpace button, I'd like to make my code delete the last character of the txt file instead of FileWrite ($historic, 'BACKSPACE') .. 


 Is there a special character that can delete my last char in the txt file ? I remember doing domething like that in C but it was years ago and I was beginning... 

Thanks for your help ! :)

This should help you get started: StringTrimRight

Snips & Scripts


My Snips: graphCPUTemp ~ getENVvars
My Scripts: Short-Order Encrypter - message and file encryption V1.6.1 ~ AuPad - Notepad written entirely in AutoIt V1.9.4

Thanks MikahS, 

So, if I understand, I have to read the whole .txt file as a string, remove 1 char from this string, and write the result in the .txt file ?

There are many ways you can go about doing this. I like using the _FileReadToArray, depending on if you have a way to split the lines (otherwise just do FileOpen w/ overwrite, FileRead, StringTrimRight, FileWrite, FileClose), use the count, which would be under index 0, and trim the string as you see fit, then write the array back using _FileWriteFromArray with FileOpen in overwrite mode. 

Let me know if you have any questions, as there is multiple ways of going about achieving what you would like.

      [SOLVED] How to search through a column and delete certain names.
      By nooneclose
      My program has to first search for names in Column D that do not match up with column C. I got that search to work using arrays. It was slow and I could not figure out how to delete them so I just manually put coded the names that do not belong. I found their cell location but I do not know how to store that location and delete it.
      This is what I have so far.
      Local $NameToDelete1[6]  = _Excel_RangeFind($OpenWorkbook, "Smith, Bill") _ArrayDisplay($NameToDelete1, "Excel UDF: _Excel_RangeFind Example 1", "", 0, "|", "Sheet|Name|Cell|Value|Formula|Comment") _Excel_RangeDelete($OpenWorkbook.ActiveSheet, $NameToDelete1[2], $xlShiftUp)  
      Please help, I wanted to have this program done yesterday but I did not see this problem until yesterday.

      Deleting/overwriting variable contents in memory
      By CarlD
      Is there a reliable way to ensure that data assigned to variables in a script is overwritten or deleted when the script exits? I have scripts that encrypt/decrypt data and would like to ensure, if possible, that the encryption keys and decrypted data do not stay in memory after the script exits. Thanks.

      FTP, delete non empty Directory - (Moved)
      By Sally1801
      Hello,
      i need help in deleting files from a server. The function "_FTP_DirDelete" only deletes a directory when its empty. I need to delete a non empty directory. I also can not delete the files in this directory first, because the files are PAG and DIR files in a .DAV directory and FTPEx.au3 doesnt like a directory starting with a ".".
      Any ideas?
      Thx, Sally

      Read and write Icloud txt files
      By wimhek
      Is it possible , and how can I read and write txt files from Icloud (apple service) ?
      Let me try to explain my application.
      On my Ipad and Iphone I create txt files. On my windows computer it is possible to read and modify these files manually, by logging in on www.icloud.com.
      What I want to make is an auto-it script who reads the txt file and create an new txt file on www.icloud.com,  so I can acces these on my ipad and/or phone.
       
      Thank you.
