Enhanced example for unitary tests:

#include "FiveWin.ch"

   local hWebView

   hDLL = LoadLibrary( "webview.dll" )

   hWebView = WebView_Create( 0, 0 )
   WebView_Navigate( hWebView, Html() ) // or use an URL
   SysWait( 2 )
   WebView_Bind( hWebView, "SendToFWH", SendToFWHAddress(), hWebView )

   WebView_Eval( hWebView, 'document.getElementById( "user" ).value = "fivetech"' )
   WebView_Eval( hWebView, 'document.getElementById( "passwd" ).value = "1234"' )
   SysWait( 2 )
   WebView_Eval( hWebView, 'document.getElementById( "submit" ).click()' )
   
   WebView_Run( hWebView )
   WebView_Destroy( hWebView )

   FreeLibrary( hDLL )

return nil

function WebView_SaveValues( cCalls, cJsonResult )

   s_nCalls = Val( cCalls )

   WebView_Navigate( hWebView, Html() ) // or use an URL
   WebView_Bind( hWebView, "SendToFWH", SendToFWHAddress(), hWebView )
   SysWait( 2 )
   
   WebView_Eval( hWebView, 'document.getElementById( "user" ).value = "fivetech"' )
   WebView_Eval( hWebView, 'document.getElementById( "passwd" ).value = "1234"' )
   SysWait( 2 )
   WebView_Eval( hWebView, 'document.getElementById( "submit" ).click()' )

   WebView_Run( hWebView )
   WebView_Destroy( hWebView )

   FreeLibrary( hDLL )

return nil

Very good Antonio,

But I could not understand one point. We try to fill the webpage directly. We have no source html.

I want to ask, is it necessary to be a web page under our control to fill the fields with WebView?

We can use any web :-)

Basically this is the functionality that you get using "Selenium" or any "web scrapper"

Now we have that power from our FWH apps !!!

Hi Antonio,

I have changed your code like that
Code: Select all  Expand view  RUN
  hWebView = WebView_Create( 0, 0 )
   WebView_Navigate( hWebView, "https://forums.fivetechsupport.com/ucp.php?mode=login" ) // or use an URL
   WebView_Bind( hWebView, "SendToFWH", SendToFWHAddress(), hWebView )
   SysWait( 2 )
   
   WebView_Eval( hWebView, 'document.getElementById( "username" ).value = "Horizon"' )
   WebView_Eval( hWebView, 'document.getElementById( "password" ).value = "12345"' )
   SysWait( 2 )
   WebView_Eval( hWebView, 'document.getElementByClass( "button1" ).click()' )


My Username and password is filled to related input fields but i could not clicked the button. I tried getElementByName("login") also.

Hakan ONEMLI

Try it with:

WebView_Eval( hWebView, 'document.getElementByClassName( "button1" ).click()' )

or

WebView_Eval( hWebView, 'document.getElementByClassName( "button1" )[ 0 ].click()' )

Leandro,

Comprueba si te funciona el EXE publicado con las DLLs que incluye, antes de instalar nada:
https://github.com/FiveTechSoft/FWH_tools/raw/master/webview.zip

Si no funciona y además genera un fichero log de error, entonces instala EverGreen Standalone Installer x86

gracias!

Perfecto Antonio, funciono sin ningún problema el ejecutable de ejemplo.

Ahora se vienen varias preguntas :D

* Es funcional con la versión de fw1909 <- Aun que tenemos otras versiones mas recientes no hemos podido migrar por que hay algunos problemas al momento de migrar, en GETS y en MEMOEDIT()

* Funciona con xHarbour?

* Se puede incrustar dentro de cualquier control?

Leandro,

Tienes que probarlo, haciendo buildh32.bat webview y comprobando si te funciona bien. Debería funcionarte bien :-)

> Funciona con xHarbour?

Sólo lo hemos probado con Harbour por el momento

> * Se puede incrustar dentro de cualquier control?

Si, usando SetParent( hWndWebView, hWndParent )
