• SQL Server merge agent error

  Hi We are using HTTPS merge replication. One of my subscribers is getting this error: Error messages: The Merge Agent failed after detecting that retention-based metadata cleanup has deleted metadata at the Publisher for changes not yet sent to the Subscriber. You must reinitialize the subscription (without upload). (Source: MSSQL_REPL, Error number: MSSQL_REPL-2147199402)   This is a bit surprising - it has been working fine - and also there were no changes at the publisher (it only has one article in this publication - a stored proc) Why would this have happened The retention period is 45 days and they syn ...Show All

• Windows Forms Reselecting a value in a DataGridViewComboBoxCell if DataGridView source changes...

  Okay... this one's giving me fits. I have a DataGridView that is bound to a strongly typed collection of objects (TimeEntry).  One of the columns is a DataGridViewComboBoxCell that is bound to another strongly typed collection (UnitType) datasource. When I select the value in the dropdown, I'm capturing the object (UnitType) selected and updating the correct UnitType property in my TimeEntry object.  If something changes in my DataGridView datasource (if I add another entry), the grid updates, and all of the selections I made in the dropdowns get reset to nothing.  The values are still there in my objects. I'm trying to i ...Show All

• .NET Development NetworkStream::BeginRead/BeginWrite problems

  Hello! I've been trying to write a multithreded application responsible for connecting via TCP/IP protocol. For this I am using TcpListener and TcpClient classes from the .NET framework. Unfortunatelly my application runs not correctly ;-) I don't get any run-time errors but the received data are not the same I've transmitted over the net. I am wondering if maybe I have made some mistakes using the BeginWrite() and BeginRead() methods. Does someone have any experiance in using them. I mean: do I have to use Monitor every time I am executing a code line like that: Monitor::Enter(myTcpClient->GetStream()); myTcpClient->GetStream()-> ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Animating a leg

  hi all, I'm trying to create a simple animation of a leg. The leg would be made out of two parts and each part would be a mesh (could be just Mesh.Cylinder). I know how this should work in principle but when I have to calculate the matrices all goes wrong... Here's my idea: Given the angles of rotation for both parts rotate and position the upper part (which will maybe be someday connected to a torso) then rotate the lower part and connect it to the first one... Could someone give me a simple example of how to correctly multiply the matrices in order to achieve the desired result thank you, sa o ...Show All

• Microsoft ISV Community Center Forums Unable to trust makecert signed COM Add-in (Outlook)

  I have a COM Add-in made for Outlook that I have signed with a test certificate made with the makecert.exe utility. When starting Outlook, the add-in loads and a security warning comes up. The problem is that the checkbox that allows me to 'Always trust macros from this publisher' is disabled. Is this because I have not used the right options with the makecert.exe utility or do I need a proper certificate to be able to trust the add-in in Outlook The following options were used: makecert -sv SomeKeyName.pvk SomeCertName.cer -n "CN=Some common name And then: cert2spc SomeCertName.cer SomeCertName.spc Finally: signtool signwiz ...Show All

• Software Development for Windows Vista How to Obtain Fault from child activity in FaultHandler?

  How does a child activity obtain access to the Fault captured by a FaultHandler I have a code activity as a child of the FaultHandler. I simply want to spit out the message from the exception that was caught. I tried using the Parent property, expecting that to give me back a reference to the containing FaultHandler, but it was null. The only way I can figure is to add a property to the workflow to store the Fault in through a binding so that it is still accessible to the child code activity. This seems like a really kludgy/indirect way of handling things though. Is there some way more direct, for this specific situation, and hopefu ...Show All

• Visual Studio Unable to link MSDN with Visual Studio 2005

  Hi, I recently started using Visual Studio 2005 professional and was using the online help when I needed it. I found this to be very slow and regularly not returning the search results I would expect. I therefore downloaded the April 2005 edition of the MSDN library and successfully installed it. The problem I have is that when I press F1 in VS, I am still getting the online document viewer rather than the newly installed MSDN library. I have checked the help options in VS to only search locally but it seems to ignore that. Is there some way of telling VS that I have now installed MSDN and where to find it Thanks, Robin Charisse ...Show All

• Visual Studio 2008 (Pre-release) What happened with INotifyCollectionChanged in May CTP ?

  INotifyPropertyChanged is still there but it seems INotifyCollectionChanged was removed. What's the new interface that replaces INotifyCollectionChanged in May CTP Thanks. Aditionally: * Hyperlink.Text was removed. * WindowLoaded() is now being called when you call Show(). This will usually cause WindowLoaded to be called before AppStartup returns. This change of behavior has broken my application but it's an easy fix. ...Show All
