Windows Live Developer Forums Sample: MSN AddIn - Text to Speech
A very simple sample of a msn addin. It uses the Microsoft Speech API to read incoming messages for you. The addin needs to be strong named and added to the global assembly cach. Same goes for the COM wrapper class for sapi.dll Generate the COM wrapper object for sapi.dll. Instead of just adding a com reference to it use tlbimp.exe and generate it yourself using the .snk file you've used to sign the addin tlbimp.exe /keyfile:”c:\my path\keyfile.snk” sapi.dll gacutil /i SpeechLib.dll Add a reference in your project to SpeechLib.dll The addin: using System; using System.Collections.Generic; using System.Text; using Microsoft.Messenger; using SpeechLib; namespace MsnAddin { public class SpeechTest: IMessengerAddIn { private Messeng ...Show All

.NET Development xml serialization problems with asynchronous callback
hey guys, im developing a windows application that uses asynchronous callback as network communication technique with xml serialization for sending complex objects over the network. the problem is that at receiving the buffer to be written to the file is never written fully and in correct format. its always cutted from the middle and so the serialization always fails. any clue thanks I'm also guessing you are having the same problem I had a while back - its the way TCP is, sending out data in bursts, so your reciever appears to read all the data it recieves but actually on the next read, the rest of the data just turns up. Are you also able to post the code for your recieving end, whe ...Show All

Visual Studio Creating a Crystal Report with VB.NET and SQL Server Express 2005
Hi there, I haven't received any replies to a question I posted, so I'll try a different approach. Can anyone point me to any resources (tutorial, walkthrough, articles) on creating a report in Crystal Reports, using VB.NET 2005 and SQL Server Express 2005. Specifically how to set up a connection to SQL that can change. The structure/data in the SQL views/tables won't change, but the string used to connect to SQL will. I test on my laptop. When I hook up to the network, I need to switch my connection to the network SQL Server. Thanks in advance!

SQL Server The REAL Warehouse Sample V6 database
Regarding the code/db from the REAL project that just got released, I have no problem attaching the "REAL Sample V6" database, but the "REAL Warehouse Sample V6" database requires ENTERPRISE edition, because the default copy uses Partitioning (i.e. the PT version, although the document stated that the multi-table (MT) version is the default). I only have the STANDARD edition of SQL 2005, is there a workaround Appreciate any help. Developer edition is different from SQL Express. SQL Express is equivalent of MSDE from pre SQL 2005. Developer edition on the other hand is similar to enterprise in all its capabilities including partitioned views etc. Developers in your agency as with ...Show All
