• SQL Server Subscription Missing

  We are seeing a problem with the users of our application. If the user closes our application from running programs (as best as we can tell as we cannot repro in dev) and SQL Mobile is in the middle of an async sync, sometimes when the application restarts it fails to load the properties for replication from the database. We are using code that is nearly identical to the samples provided by MS for performing replication async. Basically, the database still exists on the device and the application can use it just fine, but when a sync starts, the database is already there, so it tries to load the properties at which point we get a message sta ...Show All

• .NET Development Socket BeginAccept Method Memory Leak?

  Hi, After copy and pasting the code from the MSDN sample "Asynchronous Server Socket Example" - http://msdn.microsoft.com/library/default.asp url=/library/en-us/cpguide/html/cpconnon-blockingserversocketexample.asp into a Windows Library project (DLL) for use in a server I'm writing, I'm finding that each request from my client application causes a growth in memory of 4-8KB in the server application.  This doesn't seem to be reclaimed at all, it just continues to grow.  Since I'm writing a server that must run unattended for long periods of time this will be a problem for me.  After googling the problem I found a forum on dot ...Show All

• SQL Server How do i add my database to "data sources"?

  I n Lesson 9 as you can see here (at 16:50), a connection is created against his .mdf database, and the dataset is shown in the "Data Source" window/panel.

The problem is that this dataset does not show up in "Data Source". Actually, i have never seen anything in that panel before, in any of the data sources i have adde ...Show All
