Every time you need to be sure that the data has been written to disk.

Let's say a "transaction" consists of 3 writes to a file. The "transaction" is fully processed when all data is being written do disk. That's when FileFlush is being needed.

You need FileFlush if you want full control over a file. But I think it is rearely used.

      As with a lot of programming, the less manual repetition done to achieve the same outcome...the better.
      I package programs for network deployment at the organization I work for. Sometimes these applications require verbose messaging to the user, and sometimes by special request we have to turn that off and deploy silently.
      The way I currently handle these 2 scenarios is this.
      I have a function that builds the splashwin display screen to variable size depending on message length, and displays the desired message to the end user.
      Then at each point throughout my script as I need to make the user aware of what is currently happening, I inject a splashwin function call with the unique message pertaining to that specific event. ie. "Installing Microsoft Office, please wait..."
      In effort to build a more universal script to handle any type of request submitted. I've incorporated a switch command of '/silent'
      If cmdlineraw detects the usage of that switch when the script is triggered it sets a variable flag, ie. $silent = "on"
      Then at every splashwin call I make, I'm prefixing it with an IF statement that checks for the flag, and then does NOT display the message if that flag is "on". Or does display it if its not. Has worked for me just fine. But while I grow my programming skills and look for more streamlined ways of handling areas I find myself creating repetition. I'm curious if I can relocate that flag check. Taking it out of every single splashwin call, and injecting it into the function itself.
      Example of how I currently display or hide the splashwin based on command line...
      If StringInStr($cmdlineraw, "/silent", 0) Then
          $SilentSwitch = "ON"
      EndIf
      If $SilentSwitch = "OFF" Then SplashWin($Uninstalling & $ProductInfo[1][0])
      Some scripts have dozens of those splashwin calls littered throughout, so Is this the best approach I can take already? Or as stated earlier, can I pull the IF statement away from the splashwin call. And left the function as a whole either activate or deactivate as a result of the command line check.

      Hello,
      I need to pull data from company intranet website. I created a script that I can give a list of project numbers and it will open up the the related webpage for each project, save the html comments for that project, then move on to the next. 
      However my problem comes in that each time I open up a project it locks it for other users, and if you just exit the page it keeps it locked, you have to actually press the "close" button on the page. So I'm not sure how to deal with this as I end up just locking every project in my name when I run my program as I don't understand the nature of how the website is built. I don't understand how to close with just using my automation code without manually having to press the stupid button. 
      My Function:
      Func Getscript($ProjectAddress) ;getting the page source code and storing it into text file for easy reading it $file = FileOpen(@ScriptDir & "\source.txt", 10) $IE = _IECreate($ProjectAddress & ".html", 0, 0) $source = _IEDocReadHTML($IE) FileWrite($file, $source) $target_source = _StringBetween($source, "<BODY>", "</BODY>") ; only take content between the specified tags _IEQuit($IE) FileClose($file) return $target_source[0] EndFunc ;==>Getscript  
      Source Code I got from website that I think is relevant:
      function closeForm(){ if(topButtonEnabled("closeButton")){ parent.mainFrame.closeForm(); } } <button id="closeButton" class="saveCloseButton" style="LEFT: 77px;" onclick=closeForm()>&nbsp;Close&nbsp;</button>  
      Any Ideas of how to tell website to either activate the closeform function or just give it the command to close?
       
      Thanks

      Hi,
      I wonder if
      AutoIt3Wrapper_run_debug_mode = Y can include run information about functions which are called within the main code. So far I noticed in the console that the function itself is called but no specific run information from  inside the function is provided. Is there a chance to show the entire debug log including functions in the console?
      I furthermore noticed a stop of information when a loop is entered. What could be the reason for that?
       
      Thanks for help.

      Junior Programmer here... 
      Not much experience with opening, changing and closing files.
      I am trying to replace strings in a Text file except StringReplace does not actually replace the text.
      Here is a sample of my code...
      #include <File.au3> #include <MsgBoxConstants.au3> #include <WinAPIFiles.au3> Local $iStrReturn = 0 Local $hFile Local $sText Local $sNewText ; Location of File to be read $sFileName = "C:\Temp\MyPlayer.exe.config" ; The default is FALSE. We want to change this to TRUE $bLoopChecked = True CheckBox() Func Checkbox() $hFile = FileOpen($sFileName,$FO_READ) ; Open file in read mode to get text If $hFile = -1 Then MsgBox($MB_SYSTEMMODAL, "", "An error occurred when Opening the file.") Exit EndIf FileSetPos($hFile, 0, 0) ; No idea if I need to do this, grasping at straws $sText = FileRead($hFile) ; Read the file into $sText If $sText = 1 Then MsgBox($MB_SYSTEMMODAL, "", "An error occurred when reading/writing the file.") Exit Else FileClose($hFile) ; Finished reading the file into $sText, so close the file. FileFlush($hFile) ; Manual says to use FileFlush between File Close and Open so here it is EndIf MsgBox(0,"Before Replacement",$sText) ; Displays the text read from the file to make sure something is there. ; Loop Check If $bLoopChecked = True Then ; Find the string return > 0 for success $iStrReturn = StringInStr('"<add key="LoopCheckbox" value=""False" />"', "False") ;MsgBox(0,"", "LoopCheckBox is " & $iStrReturn) If $iStrReturn > 0 Then ; If StringInStr returned > 0 the it found the string! ; The Meat of the code. This is where we have to replace "False" with "True" $sNewText = StringReplace($sText, '"<add key="LoopCheckbox" value="False" />"', '"<add key="LoopCheckbox" value="True" />"') MsgBox(0,"After Replacement",$sNewText) ; Display the text to see if it worked. $hFile = FileOpen($sFileName,$FO_OVERWRITE) ; Reopen the file to write to it, overwriting everything. FileWrite($hFile,$sNewText) ; Write the text to the file FileClose($hFile) ; Close the file EndIf EndIf EndFunc This is the file I am reading...
      <?xml version="1.0" encoding="utf-8"?> <configuration> <startup> <supportedRuntime version="v4.0" sku=".NETFramework,Version=v4.6"/> </startup> <appSettings> <add key="LoopCheckbox" value="false"/> </appSettings> </configuration> I tried opening the file with $FO_UTF8 and $FO_UTF8_NOBOM but got errors opening the file.
      The MsgBox "After Replacement" shows the value is still false.
