WSE 3.0 - Modifying the Security element

Hi everyone, I'm hoping someone can help.  I'm building a SOAP client application that passed messages to a sever outside of my control.  Using WSE 3.0 and VS 2005 I'm able to generate the SOAP envelope correctly except for 1 of the server's requirements.  The specification requires that I place a specific element inside the wsse:Security element of the SOAP header.  The end result should look something like this: <wsse:Security><customnode></customnode>[other security info]</Security>. I've tried to do this with custom policies / appending a XML element to the Security node. Any help would be greatly appreciated. Thanks, John.  

UpdatePanel is not a known element - message when upgrading to 1.0 ajax


It worked on one of my old pages.  I change the web.config, renamed all the <asp.

On some aspx page it doesn't recognize the updatepanel.  It only does on one page.  If I create a new aspx page with a different name - then it works.

Should I just create a new web project ajax - then copy all my code into there?  Or is there a way to get those old pages to recognize the new ajax controls?

Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap



I created 2 projects in my solution:

  1. Classic asp.net web service (asmx)
  2. Class library project which references service
  3. web site project which references class library project
  4. Windows app project which references service.

Both projects were created in 3.5 framework and in Visual Studio 2008 Beta 2.

I added web service reference to Class library project. When it asked for namespace I typed "CurrencyProxy". Projects build ok, but when I run web app, Class library throws an error: Could not find default endpoint element that references contract 'CurrencyProxy.CurrencyServiceSoap' in the ServiceModel client configuration section. This might be because no configuration file was found for your application, or because no endpoint element matching this contract could be found in the client element.

I believe it has something to do with app.config in Class library project. Here is part from app.config:

<binding name="CurrencyServiceSoap" closeTimeout=

'element.className' is null or not an object



I just downloaded the project, compiled it and ran it right out of the box and when I put the mouse pointer over or remove the mouse pointer from either MenuItem in the menu demo, I generate this error:

'element.className' is null or not an object

It points to this javascript method:

updateClassName: function(operation, element, name, value) {
        this[operation + 'String'](
                function() {
                    return element.className;
                function(newValue) {

'Unspecified error' doing sp_xml_preparedocument on XML element with a long attribute

In SQL Management Studio 2008 (connected to SQL 2005 database), I get this:The XML parse error 0x80004005 occurred on line number 2, near the XML text "<item value="&#xD;&#xA;libname...Msg 6602, Level 16, State 2, Procedure sp_xml_preparedocument, Line 1The error description is 'Unspecified error'.When I do this declare @doc nvarchar(max), @idoc int set @doc = '<item value="&#xD;&#xA;libname..." />' EXEC sp_xml_preparedocument @idoc OUTPUT, @doc when the value of the @value attribute is actually a string of somewhat over 830000 characters.If I truncate the string somewhat, the statements execute successfully.Anyone know how to fix this?  (and "use shorter attributes" is not an acceptable answer :-)I would use XQuery except that I can't figure out how to get the equivalent of @mp:id and @mpparentid to give me the hierarchical structure information I need.  If anyone knows how to do that, I'd appreciate a hand there too!
