XMLHTTP doesn't work, I'm getting access denied

TheMSsForum.com: The Microsoft Software Forum

Hello,

I need to write a web application for my pocket PC, here is part of the
code I'm using:

xrequest = new ActiveXObject("Microsoft.XMLHTTP");
xrequest.open("POST",url,true );

I'm getting access denied when trying to execute the open method.

The same code works fine when running it using scripting host on the same
pocket PC. Also, the same code works fine on another iPaq I have that uses
win CE 4

Trying to change the security setting in the registry didn't help.

Can someone please help

Thanks,
Shlomi

This is a known problem which affects certain builds of Pocket PC 2003 and
all builds of Pocket PC 2003 Second Edition. The workaround is pretty
complicated, and involves creating an ActiveX control using ATL and
embedding it in the web page. Other than the complexity of the workaround,
the main disadvantage to this approach is that it means your end users must
download, install and register the ActiveX control before they can use your
HTML content. Unfortunately, there is no other way around the problem.

If you are familiar with creating ATL controls, the process is pretty
straightforward. Start by creating an ATL project and add a simple object
to it - let's call the control "ComAdapter" and the object "ComObject".
Then add the following method to the object:

STDMETHODIMP GetInterface
(
/*[in]*/ BSTR bstrObj, // Name of the object
/*[out, retval]*/ VARIANT *pvarObj // Returned object
)
{
CComPtr<IDispatch> pObj;
IDispatch* pDispatch = NULL;
HRESULT hr = pObj.CoCreateInstance( bstrObj );

if( SUCCEEDED( hr ) )
{
if( pObj )
hr = pObj->QueryInterface( IID_IDispatch,
(void**)&pDispatch );
else
hr = E_NOINTERFACE;
}

VariantClear( pvarObj );
V_VT( pvarObj ) = VT_DISPATCH;
V_DISPATCH( pvarObj ) = pDispatch;

return hr;
}

Finally, you will need to make some changes to your HTML code - something
like this:

var objXML = new ActiveXObject( "ComAdapter.ComObject" );
var objRealXML = objXML.GetInterface( "Microsoft.XMLHTTP" );
objRealXML.open( "POST", url, true );

Thank you very much for your support. I will give it a try.

I saw another workaround, setting a new registry key as follow:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Internet
Settings a DWORD value named "Security_AccessCrossDomainData" and set it to
1.

I tried it with no success. Is there a different registry key that might
solve this problem without coding?

I'm trying to implement your solution, I've created the dll and loaded it to
the iPaq, I'm getting an error from Javascript for sending the wrong number
of parameters for the GetInterface method. From what I understand
GetInterface should return the object in pvarObj, who do I use that in
Javascript?

Does Microsoft intend to distribute a solution for this problem?

Short answer: I don't know.

Long answer: I think there is a registry key to work around the problem,
but I'm not sure what it is.

Sorry!

If you specified the second parameter in the IDL using [out, retval], then
you will only need one parameter in the JScript code. The correct IDL
definition would be something like:

[
object,
uuid( ...your GUID here... ),
dual,
helpstring("IComObject Interface"),
pointer_default(unique)
]
interface IComObject : IDispatch
{
[
id(1),
helpstring("Returns the requested object interface.")
]
HRESULT GetInterface( [in] BSTR bstrObj, [out, retval] VARIANT*
pvarObj );
};


I'm not sure if there are plans to create a sample for this workaround, but
a KB has been requested.

Hi Mr. leweis.


I read your answer - but it's not complete, it is dealing only in one aspect
in the problem.

Ok, so we don't need to send the second parameter in the java script,

but in this parameter the reference to the object is should be returned.

so how there is a way to retrieve the object pointer???

the methods itself return an HRESULT type, which is actually a long.

how can we get the reference to the object that has been created in
GetInterface() method.


Example:

You gave us this code for using the object:

var objXML = new ActiveXObject( "ComAdapter.ComObject" );
var objRealXML = objXML.GetInterface( "Microsoft.XMLHTTP" );


In your example the objRealXML variable will hold a reference to the
"Microsoft.XMLHTTP" COM object, but the return value of the GetInterface()
is HRESULT , as declared in the idl file:

HRESULT GetInterface( [in] BSTR bstrObj, [out, retval] VARIANT*
pvarObj );


How can we get the VARIANT* pvarObj , which hold the reference to the
"Microsoft.XMLHTTP" COM object, from a Java Script code.

Thanks for your support,

Eli

The JScript code will work correctly as shown. The "[out, retval]"
declaration specifies that the function will return the object directly.
If you wanted to access the HRESULT return value, you would have to do that
directly from a language such as C++. Please give it a try, and you will
see what I mean.

I'm sorry but it is not working. First, calling the function with only one
parameter ends in an error saying this is the wrong number of parameters.
I've add another parameter just so the function will be called correctly and
it did, but I'm getting "undefined" in the return object: objRealXML.

Just out of curiosity, am I the first one to encounter this problem? Is

I think that is probably related to your news reader software - it shows up
fine in the news reader we use here, and also in Outlook Express. Try
