• SharePoint Products and Technologies debugging workflows

  Hi I followed the instructions here to create a custom workflow using infopath forms. I got it compiled and installed fine. http://weblog.vb-tech.com/nick/archive/2006/09/04/1753.aspx I was able to create a workflow for a document library based on my code, but when I run it from an item in a doc library it died with a status "failed on start" So I loaded up VS2005 project on my dev MOSS07 server and attached to the w3wp process that was executing workflow code. I see symbols loaded up for various components. But none of my breakpoints show up, saying the "symbols cannot be loaded". The symbol file is created along with my DLL. The installer puts my DLL into the GAC. How does with work with symbol files ...Show All

• Visual Basic Problem calculating icmp packet checksum

  Hi all, I am trying to create code to generate the checksum for an Icmpv6 packet. I am using vb.net to manually create an echo request icmp message and then use a socket to send and receive the replies. My problem is that the resulting checksum is wrong according to captured packets from ethereal. This code is part of my dissertation and I am desperate to find a solution. Any help will be really appreciated. The checksum code is below: Public Sub getChecksum() Dim data() As Byte = getBytes() Dim packetsize As Integer = MessageSize + 8 Dim i As Integer Dim chksm As Integer = 0 For i = 0 To packetsize - 1 Step 2 chksm += Convert.ToInt32(data(i) * &H100 + data(i + 1)) Ne ...Show All

• Visual C++ /MTd and /clr options are incompatible. Why?

  Ok, here is the long story. I have a nice C++ component which statically links to about 10 libraries as well as links to ATL, C run-time library and MFC. Component is multi-threaded and it actually runs couple of threads inside but everything is nicely wrapped into one DLL which can be called from any .NET program. It was all fine until I tried to migrate this project from VS 2002 to VS 2005. After migration at first I got this message: Building MFC application with /MD (CRT dll version) requires MFC shared dll version. Please #define _AFXDLL or do not use /MD I checked settings and saw that migration changed runtime library option to Multi-threaded DLL instead of just Multi threaded. Well, I have no intention of having 10+ DLLs instead o ...Show All

• Visual C# Help with C# Screencapture --> avi

  Hello, I was exploring the possibility of creating a multi threaded screencapture program, that exports the onscreen content to an avi file in real time. I have looked around the MSDN help areas and cannot seem to find the information I need, such as how to capture the screen's image and put that into video format or capture the audio from either the stereo output, or mic. From the information I did find I am guessing that I will need to employ the threading and AVIfile classes. Any help would be great, thanks. you need to some how capture it to a video format - how is this done no idea, probably using the DirectX approach. To capture screen shots to an image file, take a look at this: http://forums.microsoft.com/MSDN/ShowPost.asp ...Show All

• .NET Development SQLDataReader.GetOrdinal() fails rarely with IndexOutOfRange

  Hi everybody, We were developed some Web-Services that run against SQL Server 2000 with SQLDataReader that executing Stored Procedures in the DB. Most of time (95%) everything is running well, but sometimes (when exactly, we don't know) the same WebService that worked 200 times, fail. The code is simple:         public string myFunction( int ANumber )         {             string strRetVal = null ;             SqlDataReader myReader = null ;             SqlConnection MyConn = null ;             ...Show All

• .NET Development Getting Length of the Request Stream!!!

  I'm implementing a custom sink and so I have a class that implements the IClientChannelSink interface. In the implementation of the ProcessMessage method of this interface, I need the length of the request stream. [C#] void ProcessMessage( IMessage msg , ITransportHeaders requestHeaders , Stream requestStream , out ITransportHeaders responseHeaders , out Stream responseStream ); I simply used len = requestStream.Length; and there was no compile error for this. But at runtime I catch an exception that is complaining about a missing method named get_Length(). What else could I do I see. You'll probably need to buffer the stream up to ...Show All

• Internet Explorer Development Bug: Valid XHTML+CSS locks up IE7

  Hello, I have recently put up a new design for my personal website and it is causing some problems for my family/friends that use IE7. When trying to access the site IE7 locks up and is pegged at around 50% cpu usage (causing me to believe this may be an infinite loop issue). The site validates as valid XHTML and CSS. No javascript is used. Every other browser works fine.

• .NET Development Trace.Refresh() call fails

I tried to edit app.config from FarManager application's editor and from notepad. How i can refresh the Trace object without getting this exception Thank you Yes. It seems your guess was correct.

• Visual Basic How to cast to the parametrized type?

  In my application, I have got a subroutine, which should retrieve the active window, check its type and return it in case of success. I wrote it with the generics syntax: Private Function ActiveWindow( Of T)() As T Dim f As Form = Me .ActiveMdiChild If TypeOf f Is T Then Return DirectCast (f, T) Else Return Nothing End If End Function But compiler says that System.Windows.Forms.Form cannot be converted to the type T. As you can see from this code, f can always be converted to the type T. I have found out really weird thing about that. If we modify the code in the following way, everything works: Private Function ActiveWindow( Of T)() As T Dim f As Form = Me ...Show All
