Program doesn't write to files

8 posts in this topic

I've written a short program that calculates all values of a mathematical function in a user-defined interval. The data is written to an user-defined file during that process. Unfortunately, there is no file. I don't have a clue what's wrong with my program, and I've been trying to solve that for nearly 2 hours now. Obviously without success.

The calculation is done properly (added a ConsoleWrite() to check that), so it must be the FileWrite() that doesn't work.

Thanks for the help!

You need to add some error checking to your script.
Is FileOpen successful? Is FileWrite successful?
The help file shows you how to check for errors.

How do I do error checking exactly?

I don't know if that is successful. The only things I know are that the file isn't created :/

The help file explains what is returned by a function in case of an error. Example:

$f = FileOpen(...)
$If $F = -1 Then ... ; An error has occurred

$fw = FileWrite(...)
If $fw = 0 Then .. ; An error has occurred

FileOpen() and FileWrite() don't work. 

 

Edit: I guess FileWrite() doesn't work, because FileOpen() doesn't work in the first place

The default mode for FileOpen is $FO_READ.
To write to a file you need to set the mode:

#include <FileConstants.au3>
$f = FileOpen("Your filename goes here", $FO_APPEND) ; Or $FO_OVERWRITE if you always want to overwrite an existing file

      MS Splash Screens
      The office 2016/17 office suite has made many people turn heads with its functions and especially their splash screen.
      I now present to you, the MS Style Splash Screen. For Rookies, Novices and anyone who wants a ready made splash screen for your gui application.

      You can now download it and also try it out yourself.
      You have three colors to choose from:
      Blue
      Red
      Green
      All three colours are from the famous programs.
      I also included the KODA form to you can have freedom with this splash screen.
      Note: the KODA form does not have the three colours as well as the correct blue. 

      Have fun and enjoy.
      Note:
      I will update the splash to add the automated 3 dots animation at a later stage.

      A gui splash screen. Themed after the famous MS Office Suite.
      Three colours to choose from, Red, Blue and Green.
      You can change the labels to your own application.

      Also bundled with this is the KODA form. So you can open up and see the basic structure of this splash screen.

      Hello all,
      I've been trying to figure out how to launch Google Chrome in the background (hidden) but it doesn't seem possible. I've tried the following methods:
      ShellExecute("C:\Program Files (x86)\Google\Chrome\Application\chrome.exe", "", "", "", @SW_HIDE) Also I've tried:
      ShellExecute(@ComSpec, "/c start chrome.exe","","",@SW_HIDE) Lastly I tried:
      RunWait('"'&@ProgramFilesDir&'\Google\Chrome\Application\chrome.exe" --silent-launch',@ScriptDir)  
      But all of them launch my chrome browser without hiding it. Does anyone know a workaround for this or if AutoIT just can't Chrome? 
      Bonus points if you know how to make it launch chrome hidden and make it go to https://www.autoitscript.com
       
      Thank you,

      I have a working program currently driven largely through menu selections. I would like to add a toolbar where most of the tollbar button actions are basically the same as menu items, but quicker to access. I have been wading around in toolbar examples, MSDN pages etc, it's clearly going to be a bit of a slog to get everything right, including tooltips etc. I thought I would start with something simple to prove the principle.
      Using bits from the help file examples I have a small program that successfully displays a toolbar. However, what seemed like the most elegant way to deal with the button commands does not seem to work. My understanding was that a toolbar button fires a WM_COMMAND message, with the command Id set by the second parameter in the call to
      _GUICtrlToolbar_AddButton ( $hWnd, $iID, $iImage)
      so I though it would be a good idea to set this Id to the same value as my menu item Id; then it would run the same task which is what I wanted. This did not work. I am using message loop mode and would like to stick with this because some of my scripts run hardware at the same time as the gui; it is easier if I don't have to worry about code being interrupted with the hardware in an unknown state . So I added a handler for WM_COMMAND, with some cribbed display code to try and see why. The toolbar button defintely fired a WM_COMMAND message and the Id looked the same, so no explanation there.
      I guess the issue is with GUIGetMsg() which may be constructed to ignore all but a limited number of control handles, i.e. those made with the GuiCtrlCreate... commands; this is speculation.
      I would dearly love to find a tidy way to get around this. Having some controls handled in the message loop and some in a WM_COMMAND handler, performing the same task, feels ugly. I would be very grateful for further insight from someone experienced with handling a toolbar. Perhaps I should be trying to fire the menu item. I have attached a code snippet to try and illustrate the issue.

      Hello all,
      I've been working on 4 standalone scripts. They each have their own GUI and are now independent .exe's. But instead of having 4 separate icons on my computer, is it possible to put them all together into one .exe?
      What I want is one interface with tabs. Each script's GUI would be on their own respective tab. Is this possible?
      The different scripts don't need to communicate with one another. I just want them all in one .exe.
      I can't find this anywhere... Any help would be greatly appreciated. Thank you!
