• Software Development for Windows Vista OwnershipTimeoutSeconds does not work

  Hi, In order to be scalable we have two servers running our workflows. Any server should be able to take over at any time. The workflows running on the servers make asynchronous requests via msmq to other services. The replies should be able to come back to any one of the servers and still be processed. What happens is that when the reply comes back to a server which did not make the original request (and then wait on an event), the server cannot fire the event on the persisted workflow, because it's still "locked" for use by the workflow. I am currently configuring the workflow instance ownership to be 2 seconds, and it takes longer than that before the response comes back to the server. I'm using the released version o ...Show All

• SQL Server Nested Transactions

  Can anyone verify for me whether SQL Server CE 2.0 does or does not support nested Transactions when using the SQLServerCe Data Provider The SQL Server CE Books Online documentation definitely states that SQL Server CE supports nested Transactions, but the example provided uses ADOCE Data Provider. The error message that I get when trying to begin a new Transaction with an existing Transaction still uncommitted on the same SqlCeConnection is "SQL Server CE does not support parallel transactions". Is it not possible to nest Transactions with SQLServerCE Data Provider Thanks for the information. I didn't know that.

• Visual Basic Multiply long integer.

  Hi everybody, I want to translate this piece of code from C to VB 2005: static unsigned long long mt; void srand64(U64 seed) { mt = 6364136223846793005 * seed; // seed = 5489 } But i receive an overflow exception when i try this in VB 2005. i declared my variable of type ulong. Also in C the result exceed the maximum value, but I don't receive any error and the result is 13057201162865595358. How i can do to get the same value in VB 2005 Thank's all Andrea By default in VB, the compiler compiles code with overflow checking and will throw an exception if the result overflows. To get non-overflow checking semantics, you need to turn off overflow checking in the pr ...Show All

• .NET Development How to keep a thread running?

  Hi, I have the following issue and the odd part about is that I had it already working however I don't know what I changed that it doesn't anymore. I runtime compile a class, create an instance of it and init it on a different thread. In this init the class subscribes to a couple data dispatchers and should now wait for incoming data. When I first implemented this it kept running after I subscribed to the dispatchers until I aborted the thread. However, now it subscribes and after that exits the thread. Any idea how I can keep it running without putting it in a wait loop Thanks, Tom A while(true) loop in the thread should do it. :) Or a Thread.Sleep() Dont!! Just Kidding. You have to give us more info ...Show All

• Visual C# Diff between internal & protected internal modifiers..

  hi, We know that if we declare anything as internal, that will be accessible within the assembly. And any protected members will be accessed by the subclasses within the assembly. But what is the use of declaring a member as protected internal Any one pls, help me in this regard... thanx... Hi, It is indeed a bit confusing but if you read below you will see the difference: protected Access is limited to the containing class or types derived from the containing class. internal Access is limited to the current assembly. protected internal Access is limited to the current assembly or types derived from the containing class. The important part is the last OR . Do you understand the difference Greetz, Gee ...Show All

• Visual C++ COM newbie question

  when i use COM objects from C++ i need GUID and interfaces definitions.. i usually get them from an header. I noticed also that when i add a reference to a COM object (dll) in a C# project, the enviroment get directly all those informations about classes and interfaces. this suggest me that i could use COM objects even without headers. So my question is, it is possible to retrieve guids and interfaces definitions from a com object thanks to everyone in advice :) C# IDE does this by reading COM component type library. To to the same in C++ use #import directory with COM Dll name. It reads type library and generates wrapper C++ class which can be used by client code. ...Show All
