So sample code to illustrate the problem.  When I try to navigate the olecontrol to a page that uses  javescript I get an error (see picture).  Not sure how to get the webpage to work properly in the oleControl. Any help would be appreciated.


ox = CreateObject("MyInternetExplorer")
ox.visible = .t.
ox.oweb.navigate("http://mintpal.com")
 
 
DEFINE CLASS MyInternetExplorer AS form
    ADD OBJECT oWeb AS CWeb
    caption = "My Internet Explorer"
    PROCEDURE init
        THISFORM.LEFT = 0
        THISFORM.WIDTH = SYSMETRIC(1) * 3/4
        THISFORM.height = SYSMETRIC(2)*3/4
        THIS.Resize
    PROCEDURE resize
        This.oWeb.resize
    
ENDDEFINE
 
DEFINE CLASS CWeb AS olecontrol
    oleclass = "Shell.Explorer.2"
    PROCEDURE Resize
        THIS.Width = THISFORM.Width - 10
        THIS.Height = THISFORM.Height - 10
    PROCEDURE Refresh
        nodefault
ENDDEFINE

Add following line before the Navigate method call:

ox.oweb.silent = .T.

Ok, I added the silent = .t. and it suppresses the error messages which is good.  But is there a way to allow the javascrypt to run and not generate the error in the first place?

Revised from above
ox = CreateObject("MyInternetExplorer")
ox.visible = .t.
ox.oweb.silent = .T. 
ox.oweb.navigate("http://mintpal.com")

It is difficult to write JavaScript code compatible to all existing browsers or browser OLE controls. It is similar like the FoxPro code running under various FoxPro versions...

Your only option is to ask the JavaScript code author for a fix.

Your web page example is not so bad. Some scripts do not run at all under certain browsers or they just freeze the browser...

so is nothing to be done to have it in a window inside a form that will work with javascrypt?

I wouldn't tell it so strictly... The JS code works inside the form in your case just some error messages are suppressed.

Windows does not mean perfect World... And better (and cost effective) solution does not exist in this case.

BTW, why did you select your post as the solution?

What was the javascript error anyway? It's an error in the javascript code, neither in VFP nor in IE, nor in the Webbrowser Control, it just shows there.

So either it's as simple as allowing javascript at all in you IE internet settings, or let the developers of mintpal.com fix it.

Bye, Olaf.
