ISOAPReader::Load method failing for large XML's

ISOAPReader::Load method failing for large XML's

I am trying to access a function via SOAP call, sending a data in XML
format of size exceeding 5 MB. The load method is failing with return
value E_INVALIDARG.
Is there some limitation on the size of data that can be passed via a
SOAP call ?
There is also a property method for ISOAPConnector which can be used
to set certain properties for the same. Is there any property which
places a limit on the amount of data being passed through the SOAP
call ?

From SOAP toolkit3 help:

Specifying an ISAPI Listener
If specifying the ISAPI handler, you can use the registry key, 
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\MSSOAP\30\SOAPISAP, to change the 
default values of the following configuration variables:

  a.. MaxPostSize - the maximum size of the SOAP message that you can POST 
to the ISAPI handler; the default is 100 KB. While this setting helps keep 
hackers from tying up your service by posting extremely large messages, you 
may need to increase the default size if your service accepts large SOAP 
messages.

Hi Villi,

Thanks for the reply.
But it does not seem to work. I changed the reg. value to correspond
to 10MB of message size, but the error still comes.

I also happened to notice that in ISOAPSerializer, there is some write
method where the XML string to be passed is attached to the stream.
Does this need some kind of setting to work with large message sizes ?

Is there some general limit on the size of XML/data which can be
transmitted over SOAP using the MS SOAP 3.0 Toolkit ?

Strange. Are you sure you're not reaching the connectortimeout time? Well, 
looks you're getting a different error, so it's probably not the timeout.

Never used that, sorry.

I believe not, I have seen XML files in the range of the 70MB goin' in & out 
flawlessly.
I can't figure out what else it may be.
