Champak Posted June 12, 2022 Share Posted June 12, 2022 I have a gui where sometimes I may want to see what is happening with the browser after an initial setup, so there is a checkbox to make the driver headless or not. Problem is I can't get it to work. I've tried a bunch of different things to change from showing the browser to headless. I've tried calling the setup multiple times with and IF condition If GUICtrlRead($gURLBrowser) = $GUI_CHECKED Then $sDesiredCapabilities = Call(SetupChrome(0)) EndIf Func SetupChrome($Headless = 1);Needed to generate the barcodes MsgBox(0,0,$Headless) _WD_Option('Driver', 'chromedriver.exe') _WD_Option('Port', 9515) _WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\chrome.log"') _WD_CapabilitiesStartup() _WD_CapabilitiesAdd('alwaysMatch', 'chrome') _WD_CapabilitiesAdd('w3c', True) If $Headless = 1 Then _WD_CapabilitiesAdd('args', '--headless') _WD_CapabilitiesAdd('excludeSwitches', 'enable-automation') _WD_CapabilitiesDump(@ScriptLineNumber) ; dump current Capabilities setting to console - only for testing in this demo Local $sDesiredCapabilities = _WD_CapabilitiesGet() Return $sDesiredCapabilities EndFunc ;==>SetupChrome I've tried the following capabilities adds together and separately before calling the browser _WD_CapabilitiesAdd('--disable-extensions') _WD_CapabilitiesAdd('--disable-gpus') _WD_CapabilitiesAdd('--headless') _WD_CapabilitiesAdd('args', '') $sDesiredCapabilities = _WD_CapabilitiesGet() Is what I'm trying to do possible?

Danp2 Posted June 12, 2022 Share Posted June 12, 2022 I'm not aware of the ability to change the browser visibility once it has been launched as "headless". However, you can control the visibility of the webdriver console using _WD_ConsoleVisible.

mLipok Posted June 12, 2022 Share Posted June 12, 2022 When you wan to switch from headless to visible then you must close previous browser instance. https://stackoverflow.com/q/49134440/5314940 Signature beginning:* Please remember: "AutoIt"..... * Wondering who uses AutoIt and what it can be used for ? * Forum Rules ** ADO.au3 UDF * POP3.au3 UDF * XML.au3 UDF * IE on Windows 11 * How to ask ChatGPT for AutoIt Code * for other useful stuff click the following button: Spoiler Any of my own code posted anywhere on the forum is available for use by others without any restriction of any kind.

Champak Posted June 12, 2022 Author Share Posted June 12, 2022 @Danp2, no I don't want to change from headless to displaying while the browser is launched. I want to change it after the $sDesiredCapabilities is set, but before the actual browser launch. ex. Global $sDesiredCapabilities = Call(SetupChrome(1)); at the top of the script then for a particular function: _WD_Startup() $sSession = _WD_CreateSession($sDesiredCapabilities) ...... _WD_DeleteSession($sSession) _WD_Shutdown() Then a different function starts that I may want to see the browser so .....show the head _WD_Startup() $sSession = _WD_CreateSession($sDesiredCapabilities) ...... _WD_DeleteSession($sSession) _WD_Shutdown() I don't understand your second post. @mLipokI don't have a previous browser launched. As it is, I've been testing it just by setting up the initial desired capabilities, and simply trying to change the headless before launching the browser for the first time to see if it would even work and it's not. like Global $sDesiredCapabilities = Call(SetupChrome(1)) $sDesiredCapabilities = Call(SetupChrome(0)) _WD_Startup() $sSession = _WD_CreateSession($sDesiredCapabilities) ...do some stuff _WD_DeleteSession($sSession) _WD_Shutdown() Func SetupChrome($Headless = 1);Needed to generate the barcodes _WD_Option('Driver', 'chromedriver.exe') _WD_Option('Port', 9515) _WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\chrome.log"') _WD_CapabilitiesStartup() _WD_CapabilitiesAdd('alwaysMatch', 'chrome') _WD_CapabilitiesAdd('w3c', True) If $Headless = 1 Then _WD_CapabilitiesAdd('args', '--headless') _WD_CapabilitiesAdd('excludeSwitches', 'enable-automation') _WD_CapabilitiesDump(@ScriptLineNumber) ; dump current Capabilities setting to console - only for testing in this demo Local $sDesiredCapabilities = _WD_CapabilitiesGet() Return $sDesiredCapabilities EndFunc ;==>SetupChrome So when you say close the previous browser instance, it isn't a factor.

Danp2 Posted June 12, 2022 Share Posted June 12, 2022 It works as I would expect after eliminating the use of Call(). Run the following and post the results -- #include "wd_helper.au3" #include "wd_capabilities.au3" Global $sDesiredCapabilities = SetupChrome(1) ;### Debug CONSOLE ↓↓↓ ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $sDesiredCapabilities = ' & $sDesiredCapabilities & @CRLF & '>Error code: ' & @error & @CRLF) $sDesiredCapabilities = SetupChrome(0) ;### Debug CONSOLE ↓↓↓ ConsoleWrite('@@ Debug(' & @ScriptLineNumber & ') : $sDesiredCapabilities = ' & $sDesiredCapabilities & @CRLF & '>Error code: ' & @error & @CRLF) Func SetupChrome($Headless = 1);Needed to generate the barcodes _WD_Option('Driver', 'chromedriver.exe') _WD_Option('Port', 9515) _WD_Option('DriverParams', '--verbose --log-path="' & @ScriptDir & '\chrome.log"') _WD_CapabilitiesStartup() _WD_CapabilitiesAdd('alwaysMatch', 'chrome') _WD_CapabilitiesAdd('w3c', True) If $Headless = 1 Then _WD_CapabilitiesAdd('args', '--headless') _WD_CapabilitiesAdd('excludeSwitches', 'enable-automation') _WD_CapabilitiesDump(@ScriptLineNumber) ; dump current Capabilities setting to console - only for testing in this demo Local $sDesiredCapabilities = _WD_CapabilitiesGet() Return $sDesiredCapabilities EndFunc ;==>SetupChrome Latest Webdriver UDF Release Webdriver Wiki FAQs Link to comment Share on other sites More sharing options...
