It's probably because you want to make sure that $bReset is actually boolean (True) as opposed to non-zero or non-empty string.

ConsoleWrite("True =  True: " & (True = True) & @CRLF)
ConsoleWrite("True == True: " & (True == True) & @CRLF)
ConsoleWrite("True =  1:    " & (True = 1) & @CRLF)
ConsoleWrite("True == 1:    " & (True == 1) & @CRLF)

If so, that means that the underlying code must be a little sloppy.  :)

Do you propose:

If IsBool($bReset) And $bReset Then $sOutputError = ''

instead my:

If $bReset == True Then $sOutputError = ''

?

Why force $bReset to actually be boolean?
AutoIt by default does the data type conversion. This happens all the time (in user scripts and UDFs) so (nearly) everyone knows what happens under the covers ;)

Even your "==" operator uses data type conversion as it "Tests if two strings are equal"

I want to be sure that in this two following functions:
 

Func _Run_Wrapper($sCommand)
    _Run_Wrapper_GetStdout(True)
    _Run_Wrapper_GetStderr(True)
    $RUN_WRAPPER_PID = Run(@ComSpec & " /c " & $sCommand, @SystemDir, @SW_HIDE, $STDERR_CHILD + $STDOUT_CHILD)
    If @error Then Return SetError($RUNWRAPPER_ERR_GENERAL, $RUNWRAPPER_EXT_DEFAULT, 0)
    Return $RUN_WRAPPER_PID
EndFunc   ;==>_Run_Wrapper

Func _Run_Wrapper_GetStdout($bReset = False)
    Local Static $sOutputRead = ""
    If $bReset == True Then $sOutputRead = ''
    $sOutputRead &= StdoutRead($RUN_WRAPPER_PID)
    If @error Then Return SetError(@error, $RUNWRAPPER_EXT_DEFAULT, $sOutputRead)

    Return SetExtended($RUNWRAPPER_EXT_NOT_FINISHED_YET, $sOutputRead)
EndFunc   ;==>_Run_Wrapper_GetStdout

the $sOutputError and $sOutputRead variables are cleared intentionally, and not by users mistake.

But after consideration in fact better will be to use Defalut (for getting) and Null (for clearing).

I like it way better with IsBool. 

You can Return SetError if not bool or like you did.  Either way is IMO more readable...

Intention of $bReset was to have possibilty to reset stored Static variable.
So you have 2 option "RESET" or "GET" (as the Function name states).
Normally user should use only "GET" feature.
So as for now I think there is no need for additionall error reporting.

btw.
"RESET" should be done only internally by _Run_Wrapper()
User should not "RESET" static variable by them self, user should only use "Default GET" feature to get last results.

I agree with @Nine, but, as stated in the Help file about == operator:

Quote

Tests if two strings are equal. Case-sensitive. The left and right values are converted to strings if they are not strings already. This operator should only be used if string comparisons need to be case-sensitive.

So, you are not asserting that $bReset is bool, indeed, you are converting both sides to strings, isn't it?

hm... maybe HelpFile should be reviewed in this .... part.

Check this following code :

Global $RUN_WRAPPER_PID
Global Enum _
        $RUNWRAPPER_ERR_SUCCESS, _
        $RUNWRAPPER_ERR_GENERAL, _
        $RUNWRAPPER_ERR_COUNTER

Global Enum _
        $RUNWRAPPER_EXT_DEFAULT, _
        $RUNWRAPPER_EXT_NOT_FINISHED_YET, _
        $RUNWRAPPER_EXT_COUNTER

_Run_Wrapper_GetStdout('by mistake')
_Run_Wrapper_GetStderr(1234)

ConsoleWrite('! ' & _Run_Wrapper_GetStdout() & @CRLF)
ConsoleWrite('! ' & _Run_Wrapper_GetStderr() & @CRLF)


Func _Run_Wrapper_GetStdout($bReset = False)
    Local Static $sOutputRead = "SIMULATION OF NORMAL STDOUT RESULT"
    If $bReset == True Then $sOutputRead = ''
;~  If $bReset = True Then $sOutputRead = ''
;~  $sOutputRead &= StdoutRead($RUN_WRAPPER_PID)
    If @error Then Return SetError(@error, $RUNWRAPPER_EXT_DEFAULT, $sOutputRead)

    Return SetExtended($RUNWRAPPER_EXT_NOT_FINISHED_YET, $sOutputRead)
EndFunc   ;==>_Run_Wrapper_GetStdout

Func _Run_Wrapper_GetStderr($bReset = False)
    Local Static $sOutputError = 'SIMULATION OF NORMAL STDERR RESULT'
    If $bReset == True Then $sOutputError = ''
;~  If $bReset = True Then $sOutputError = ''
;~  $sOutputError &= StderrRead($RUN_WRAPPER_PID)
    If @error Then Return SetError(@error, $RUNWRAPPER_EXT_DEFAULT, $sOutputError)
    Return SetExtended($RUNWRAPPER_EXT_NOT_FINISHED_YET, $sOutputError)
EndFunc   ;==>_Run_Wrapper_GetStderr

and then change:
 

;~ If $bReset == True Then $sOutputRead = ''
If $bReset = True Then $sOutputRead = ''

 

and check again.

@mLipok
Ok, I got it.
In the first example (with ==) the static variable is not emptied, while in the second one (=) it is.
That's because in the first example the condition between non-zero expression and True has been evalutated as False, while in the second one, since "everything that is not 0 is 1", then the variable has been emptied.
Not so implicit, but I have to agree with you about changing the Help file because it is a little bit misleading.
Thanks for the explanation :)

But lets take another example, that, I believe, proves that help file is correct (where both sides are converted to string) :

$bReset = True
ConsoleWrite ("bool vs string true " & ($bReset == "true") & @CRLF) ; False because "True" <> "true"
ConsoleWrite ("bool vs string True " & ($bReset == "True") & @CRLF) ; True because "True" == "True"

$bReset = true ; true is converted to True internaly
ConsoleWrite ("bool vs string true " & ($bReset == "true") & @CRLF) ; False because "True" <> "true"
ConsoleWrite ("bool vs string True " & ($bReset == "True") & @CRLF) ; True because "True" == "True"

$bReset = "True"
ConsoleWrite ("string True vs Bool " & ($bReset == true) & @CRLF) ; True because "True" == "True" (as true is converted first to True)
ConsoleWrite ("string True vs Bool " & ($bReset == True) & @CRLF) ; Same as previous but no conversion

$bReset = "true"
ConsoleWrite ("string true vs Bool " & ($bReset == true) & @CRLF) ; False because "true" <> "True" (as true is converted first to True)
ConsoleWrite ("string true vs Bool " & ($bReset == True) & @CRLF) ; False because "true" <> "True" but no conversion

I notice that

True as a Boolean
is always converted as string to "True" even when you use
true as a Boolean

Yes it is because boolean true is first converted into boolean True internally.  This is my assumption, otherwise it doesn't make sense...

Boolean True
or
boolean true

are just "positive Boolean"

      Here is the full script:

      Hi, I am trying to select elements in print page (dialog window) for a specific web page. But when trying to do so, it looks like it does not allow me to do it.
      So far, this is what I have:
      _WD_WaitElement($sSession, $_WD_LOCATOR_ByCSSSelector, "body") Local $mainpagebody = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "body") _WD_HighlightElement($sSession, $mainpagebody, 2) _WD_WaitElement($sSession, $_WD_LOCATOR_ByCSSSelector, "img.print-button") Local $printbutton = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "img.print-button") _WD_ElementAction($sSession, $printbutton, 'click') _WD_LoadWait($sSession) Sleep(3000) _WD_WaitElement($sSession, $_WD_LOCATOR_ByCSSSelector, "body") Local $printpagebody = _WD_FindElement($sSession, $_WD_LOCATOR_ByCSSSelector, "body") _WD_HighlightElement($sSession, $printpagebody, 2) The script above highlights the main web page "body" element, then clicks a tag to print a specific part of the page, then it will open a print page window where i am trying to highlight the body of that print page - but it looks like it is dropping from the session because it opens up another chrome page chrome://print.
       
      Below is the output log:

      Is it even possible to select elements in print page?

      Hello
      How can I export a sheet to pdf using the OOoCalc.au3 UDF?
      Thank you for any hints or possibly other solutions / functions.

      Hello everyone,
      I've created a UDF for basic communication with SSH servers. I know there is already such a UDF, but I wasn't satisfied with it for my purpose, so I created a new one.
      This UDF also acts as a wrapper for the plink executable. Its essential functions are _SSHConnect, _SSHSend, _SSHRecv and _SSHCloseSocket.
      It does support multiple simultaneous connections and aims to be pretty robust. Feel free to share your opinions
      Two of the included examples use a slightly modified version of Vintage Terminal by @Chimp
      Download
      The download includes ssh.au3 (UDF), plink.exe (necessary), vintage terminal and code examples:
      Version 1.0.1
      - fixed rare _SSHConnect bug where "ssh-host-key prompt" was not answered
      SSH UDF 1.0.1.zip

      Features
      Simple Integrated countermeasures against file and memory analysis based decompilers. Add basic types of resources into the interpreter or other types as raw data. Define multiple programs to execute pre and post build. Create and include pe version information. User defined patches that can be implemented globally on the interpreter and compiler or selectively. Handles its own basic macro's as well as environment variables in most fields for easier path finding. Drag and drop configs (script bound or separate) to the input edit box or to the icon to load them. Configuration settings can be copied to the clipboard or saved as config files or Au3 scripts. Settings can now be saved directly to an AutoIt3 script. Subsystem independant, can act as a gui or console tool. And much more. See next post for update information.
