Program doesn't write to files

Recommended Posts

Wicked_Caty

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

      Hello again!
      I have tried searching for quite some time now but couldn´t find a single working way to change the class of your GUI that doesn´t include changing it manually after its compilation.
      First or "AutoIt v3 GUI" is a pretty boring name tbh and i would like to spice it up a bit, also, and more importantly, I would like to identify my windows by something other than its title as it will change depending on some factors and im using two different programs independently as multi threading isn't supported.
      Any help is appreciated! Thank you!

      Hello, 
      i have a Problem with  _WinAPI_SetLayeredWindowAttributes, everything is working as excepted if u are on Windows 7.

      But if u are on Windows 10 the transparent background of a control is not clickable anymore. 

      Could someone help?

      Please see example below, put cmd.jpg into the same folder as Example.au3

      Please see trigger.jpg to see which sections are not clickable in Windows 10 (the red dots, the green dots are clickable) on Windows 7 the red ones and green ones are clickable.
       
      The same problem occurs if i use

      Hello everyones reading this post,
      I'm struggling at resizing properly my radio buttons to fit long text inside without affecting others radio buttons and also adjust position of them relative to the string.
      I tried with _StringSize UDF but I guess im too tired to figure out how to use it correctly..
      I also tried: _Control_SetWidth2Text I found on this forum, it work aslong im not maximizing GUI (radio text is gone when I maximize and maximize is a must)
       
      here is the code example, I hope someone can figure out (sorry if guictrlsetpos is not included in the example, I know thats probably the way to go but I wanted to make sure there is nothing better before use it)
      Thank you

      Hello,

      im searching like 6 hours and i didnt found the right solution.

      Im trying to build a treeview from a directory and its subfolders etc.

      This function give me right treeview, but i cant color each item seperated.

       
      #include <GuiTreeView.au3> $hGui = GUICreate("Demo1", 600, 400) $hTreeView = _GUICtrlTreeView_Create($hGui, 10, 10, 580, 380) GUISetState() _GUICtrlTreeView_BeginUpdate($hTreeView) ListFiles_ToTreeView(@ScriptDir, 0) _GUICtrlTreeView_EndUpdate($hTreeView) Do Until GUIGetMsg() = -3 Func ListFiles_ToTreeView($sSourceFolder, $hItem) Local $sFile ; Force a trailing \ If StringRight($sSourceFolder, 1) <> "\" Then $sSourceFolder &= "\" ; Start the search Local $hSearch = FileFindFirstFile($sSourceFolder & "*.*") ; If no files found then return If $hSearch = -1 Then Return ; This is where we break the recursive loop <<<<<<<<<<<<<<<<<<<<<<<<<< ; Now run through the contents of the folder While 1 ; Get next match $sFile = FileFindNextFile($hSearch) ; If no more files then close search handle and return If @error Then ExitLoop ; This is where we break the recursive loop <<<<<<<<<<<<<<<<<<<<<<<<<< ; Check if a folder If @extended Then ; If so then call the function recursively ListFiles_ToTreeView($sSourceFolder & $sFile, _GUICtrlTreeView_AddChild($hTreeView, $hItem, $sFile)) Else ; If a file than write path and name _GUICtrlTreeView_AddChild($hTreeView, $hItem, $sFile) EndIf WEnd ; Close search handle FileClose($hSearch) EndFunc ;==>ListFiles_ToTreeView
      So i am searching for the exact same function just with
      GUICtrlCreateTreeViewItem
      instead of 
      _GUICtrlTreeView_AddChild
       
      Ps: i have a folder structure where i like to color each item green if a file only exist once and red if it exist more than once.

      Could someone help?
