    - Differences between dbgclr and mdbg when looking at variables in IronPython scripts... Using ths brilliant script: import clr reallyuniquename = 12354 class myclass(): def __init__(self): a = raw_input("%") self.selfuniquename = 654321 uniquename = "uniquestuff" mc = myclass() a = raw_input(":") print "all done" And running it with ipy.exe (version 2, alpha 5) I get really different results when looking at variables in mdbg and dbgclr. For instance if I set a breakpoint in dbgclr on the line 'uniquename = "uniquestuff" and look at the locals I get: $context self Dictionary SymbolAttributes [0] and here I see uniquename set to uniquestuff yeah! uniquename $line retval where my indents indicate that I can drill down. In mdbg I get: a uniquename $line retval $context self __dict__ _keyVersion _extraKeys _values _data _nullObject ObjectKeys __class__ _weakRef I cannot find a way to find uniquename/uniquestuff. I cannot even print $context because mdbg aparently thinks it is some sort of internal variable. Why are the two debuggers showing such different results And of course the one that is 'wrong' is the one I want to use and the one that is right is closed. Thanks, David P.S. will there be a new version of mdbg with 'better behavior' soon I have seen references to a newer version - bug no timetable. Thanks!

    - Problem with sending UDP to Apple macs :( Guys I've met with a weird problem. Few years ago I wrote VB6 client-server project, later a third party developer wrote client app for Apple Mac. It was working fine until we rewrote the server part in VB.NET Problem: Macs seems to be unable to receive the UDP data sent by server from vb.net code I send it using UdpClient Code Snippet Dim MySocket As New UdpClient() MySocket.Send(DataArray, DataArray.Length, IpAddress, Port) When I send the same data from VB6 code it works fine! When I send the same data from VB.NET to PC it also works fine.... It is really confused me, is VB6 Winsock control sends the same data in a different way Unfortunately I'm unable to debug the Mac client to have look what it receives so only thing left is to guess.... Any ideas Tag: ASMX Web Services and XML Serialization Video conference using xml webservice .NET Development

    - Help ... ISymUnmanagedBinder2::GetReaderForFile2(...) returning 0x806D0005 Thanks for the details. I'm glad to hear it was around 1000 or so - seems a lot more understandable to me than if it had been only a few (eg. may be hitting OS resource limits). I unfortunately don't know the answers to your questions about updating PDBs off hand. I own the code in the CLR that uses this interface to read and write PDBs, but we never update existing PDBs - just create new ones, so I don't have any experience with what you want to do. I'll track down the people that own this interface and ask them to respond to your questions. It may be that you effectively need to create a new PDB file for changes of this magnitude.

    - Web Service Progress and Logging Hi, I've been trying to write a soap extension that allows me to log the raw soap traffic for a web service and track the upload/download progress. I've modified the code from this article... http://msdn2.microsoft.com/en-us/library/aa480520.aspx I have not problem with the response part of the message and I'm able to log it and give an update on the progress to the user. But when I try and do the same for the request part I run into errors. Essentially the stream that I get from the first ChainStream() call does not support reading. It throws an exception when I try to read it. The exception is: "The stream does not support reading." at System.Net.ConnectStream.Read(Byte[] buffer, Int32 offset, Int32 size) at System.Web.Services.Protocols.SoapExtensionStream.Read(Byte[] buffer, Int32 offset, Int32 count) etc. Any help would be appreciated, Colin Tag: ASMX Web Services and XML Serialization Video conference using xml webservice .NET Development

    - ASP.NET PostBack simulation Hi, I would like to simulate a postback on an asp.net page. I explain myself, let's say i have a page with an asp "form" so the postback is performed on the submit button click with: _WebForm_DoPostBackWithOptions(...) -> __doPostBack(...) I would like to perform the same request but with an xmlhttprequest object. i found that, in fact, i need to send by post method the values of __VIEWSTATE, __EVENTTARGET and __EVENTARGUMENT. Actually i know that my eventtarget is the submit link name and the event argument is empty (in my case). The view state is an hidden field in the page. I understood that __VIEWSTATE contains the (serialized ) values of the active controls in the page, so by sending the viewstate the page will be able to find the values and perform the correct operations. So how is generated this field before the "send" operation If anybody knows it could really help me. If im wrong in one of the statements i wrote, please tell me Thank you by advance Clement Tag: ASMX Web Services and XML Serialization Video conference using xml webservice .NET Development

    - Stream either way you are using network traffic/bandwidth since its going to be getting data from the stream - its going to be accessing the stream and getting data (using bandwidth) you could also check out an app I made a while back called DAR~ling on my site (weblink on my profile) - its a Digital Audio Recorder that records audio, with an optional url stream to record from, from a scheduled time.

    - Saving richtext into ntext-field of sql-server Hi! Just started my first programming steps. All looks fine and it seems to be fun. But now I've got a Problem: I'm trying to save a richtext out of a richtextbox oject into a ntext field on sql-server. I'm using a stored prcedure which I fill with parameters. (Yes - there is a better way - but right now, this is good enough for playing around) everything works but the rtf-part. I'm sure, that I'll have to do something with the RTF-thing - but what The error tells me, that I should use Convert to transfer the RTF-String. But this does not do the job either.

    - CLR naming conflicts MSFT Johan Stenberg wrote: Is this what you are looking for: http://msdn2.microsoft.com/en-us/library/12a7a7h3(VS.80).aspx Best regards, Johan Stenberg That explains some things but it does not explain identifier clashes in a class hierarchy. What happens in CLR when the same identifier is used for types between a base and derived class. In some languages, like C++, this is perfectly legal since each class has its own scope, and the same-named identifier in the derived class merely hides the base class identifier ( except in the case of overloaded and overridden functions) in the scope of the derived class. Is this also the way CLR works or is their a name clash and illegality in a CLR class hierarchy. I ran into a situation where I was inadvertently naming a derived class property wit the same name as a base class member function. I received no warnings or errors from the CLR compiler, which makes me believe this is perfectly legal in CLR. However the Winforms designer could not set the value of the property correctly. When I changed the property name to a unique name in the class hierarchy, the Winforms designer handled it without error. So is this a bug in the Winforms designer or is it a bug in the CLR compiler for not alerting me to a CLR illegality Of course I should not have named the property the same as a base class function, but I expect the error should have been picked up if it was illegal by the compiler, or the Winforms designer should be able to handle it if it was legal.

    - How to prevent SQL Injection with OR parameters. Good day, My method receives an arraylist of string, each string representing the first name of a client. my SELECT query is SELECT * from table1 and I build my WHERE statement dynamically like that: if (where == "" ) where += " WHERE " ; where += " FirstName like " + clientName[i ] + " " ; } else { where += " OR FirstName like " + clientName[i ] + " " ; } } return where; } to make a long story short, I concat multiple OR FirstName like clientName[i ]. However, i would prefer to do sqlComm.Parameters.AddWithValue(....) but I dont know how to procees, since I dont know the number of OR's that will be in my query.

    - StreamReader.Read method fails for multi-part data transfer We should be able to read the data irrespective of its size. I am assuming that the server is sending an EOT byte at the end of the data. Well thats fine, we should make sure that it is indeed sending the EOT character, since you are infinitely blocked on that [or the 50,000 seconds] problems like this are hard to figure out from the code, You need to make sure that you look at exactly is what is coming, You can do that with Ethereal Or with system.net trace. Actually I suspect that the StreamReader/UTF8 conversion is not going well. This is what I would do. Don't construct a stream reader. Just use the network stream. Read bytes until you get EOT and then convert all the bytes at once to UTF8. The issue is that it is entirely possible that the boundary of the buffer is falling in the middle of UTF8 encoding. This is what I would do MemoryStream ms = new MemoryStream(); byte[] buf = new byte[1024]; int read = stream [NOT STREAMREADER].Read(...); while (read > 0) { if buf[read -1] = EOT { write all the data except the EOT to MS } else { write all the data to MS } } Seek Memory stream back to oirigin Get All the bytes by converting to an array and then just use Encoding.Utf8.GetString on those bytes Tag: ASMX Web Services and XML Serialization Video conference using xml webservice .NET Development

    - "Deserializing" XmlNode.OuterXml to object, then back to XmlNode questions I am not able to reproduce the problem, both XPath and schema validation work normally for me, even when the xmlns attribute has been removed. The namespace of an element node in the DOM model is determined by its namespaceURI property and not by any namespace declaration attributes. Here is my sample code: Code Block XmlDocument doc1 = new XmlDocument (); doc1.LoadXml( "<root xmlns=\"http://example.com/ns1\"><bar/></root>" ); XmlDocument doc2 = new XmlDocument (); doc2.LoadXml( "<foo xmlns=\"http://example.com/ns1\"></foo>" ); doc2.DocumentElement.RemoveAttribute( "xmlns" , "http://www.w3.org/2000/xmlns/" ); doc1.DocumentElement.ReplaceChild(doc1.ImportNode(doc2.DocumentElement, true ), doc1.DocumentElement.FirstChild); doc1.Save( Console .Out); Console .WriteLine(); XmlNamespaceManager mgr = new XmlNamespaceManager (doc1.NameTable); mgr.AddNamespace( "pf" , "http://example.com/ns1" ); Console .WriteLine( "Number of nodes: {0}." , doc1.SelectNodes( "//pf:foo" , mgr).Count); XmlSchemaSet schemaSet = new XmlSchemaSet (); schemaSet.Add( null , @"..\..\XMLSchema1.xsd" ); doc1.Schemas = schemaSet; doc1.Validate( delegate ( object sender, ValidationEventArgs vargs) { Console .WriteLine( "{0}: {1}" , vargs.Severity, vargs.Message); }); SelectNodes finds one node and schema validation outputs a validation error.

Re: ASMX Web Services and XML Serialization Video conference using xml webservice

OmegaMan

The webservice is just a conduit for transfering data. It does not have anything to do with the data being transfered. How you setup the Xml to handle the video feed is up to you and your consumer of the data. The web service will just serve up the data to the consumer.
