Rendering webpages within BB4W application
Post by jeroengroenendaal on Feb 2nd, 2015, 2:37pm

Hello,

I am looking for a simply method to render web pages within the BB4W application.
I have tested a bit with the COM programming library, but that opens Internet Explorer in an external window.

Is this easily possible?

Many thanks for any help!

You can easily do it with an ATL control:

Code:
      INSTALL @lib$+"WINLIB5"

      SYS "LoadLibrary", "ATL.DLL" TO atl%
      SYS "GetProcAddress", atl%, "AtlAxWinInit" TO `AtlAxWinInit`
      SYS `AtlAxWinInit`

      ON CLOSE PROCcleanup : QUIT
      ON ERROR SYS "MessageBox", @hwnd%, REPORT$, 0, 0 : PROCcleanup : QUIT
      *ESC OFF

      url$ = "http://www.rtrussell.co.uk/"
      DIM rc{l%,t%,r%,b%}
      SYS "GetClientRect", @hwnd%, rc{}
      hATL% = FN_createwindow("AtlAxWin", url$, 0, 0, rc.r%, rc.b%, 0, &200000, 0)

      REPEAT
        WAIT 0
      UNTIL FALSE
      END

      DEF PROCcleanup
      hATL% += 0 : IF hATL% PROC_closewindow(hATL%) : hATL% = 0
      ENDPROC

I had some difficulties reneding some parts of my website on one of my Terminal Servers.

I have tested the output to : https://www.whatismybrowser.com/

This results that all webpages rendered in my own application probably uses the 'compatability mode' and blocks some Javascript :

So, if you use this solution, please bare in my it isn't the same experience as in your browser. (e.g. the page rendering can be different as well)

Here (Windows 8.1, Internet Explorer 11, BB4W 6.00a), http://www.whatismybrowser.com/ reports basically identical information from the ATL control and from Internet Explorer. The only significant differences are that the ATL control is reporting Internet Explorer 7 Compatibility View and the true screen resolution (1920 x 1080) - because I have set BB4W as 'DPI aware' - whereas IE is reporting a 'scaled' 96 DPI resolution (1280 x 720).

I am not seeing any difference in respect of JavaScript:

Richard,

Yes, in Internet Explorer 11 the website does work.
However, we still have a Terminal Server running Windows Server 2003 with the latest supported Internet Explorer Browser 8.0 installed.
This version does give Javascript errors using this web page.

I know, we should replace that old server. But it's a low-budget company lipsrsealed

Maybe this is a good reason the swap all Terminal users to the new environment.

However, the intranet/extranet webpage that I am going to use, does give Javascript error even in Windows 8.1. I will not give the adres to this forum, through.

Best regards,
Jeroen
