• Software Development for Windows Vista Get Workflow Runtime

  Is it possible to get WorkflowRuntime in CodeActivity if so, How You cannot get the WorkflowRuntime instance within a code activity. The reason for this is that the workflow instance runs on a separate CPU thread to the WorkflowRuntime instance and it does not include the overhead of being threadsafe. Instead you should think of this as interacting between the workflow and the host and the proper way to do this is through a service. You can use the simple service implementation in HandleExternalEvent and CallExternalMethod or you can write your own service. There are examples in the SDK and in the HO ...Show All

• Windows Forms not able to locate line of code geberating the pb

  My class frmacct is a form. Sometimes, I get the error message : 'Object not set to a reference' but the code stops and puts that 'yellow back color' at the begining of my form class: Public Class frmclass So I m don t know how to locate the line that generates the error since the debugger stops at the begining of the form Thanks Hmm, thats a little odd.

• Visual Studio Team System Duplicate Project Names

  I am running TFS Beta 3. I have a situation where I have cancelled the creation of a new project (during the phase of it downloading the templates) and now I can't re-create the project with the same name. It says it already exists, although its not available as an Add Existing Project either. Is there anything I can run on the server that will  validate all existing project data in the database Regards Graham One option is to try to force deletion of the old project.

• Visual Studio Refactor Encapsulate field repeatedly

  Hi. I have an object with more the 100 fields. I wonder if there is a method to automate the process of encapsulating those fields. I'm just too lazy to do "Right-Click -> Refactor -> Encapsulate Field" for 100 times if i select all the fields and do "Encapsulate" then only last selected field is encapsulated.   Any suggestions on this   Thanks. Hi, This is not supported in the shipped code of Class Designer. However, you can easily add this feature by creating a command yourself through an add-in. You can install the CD Power Toys add-in , create a command and insert the following co ...Show All

• SQL Server Free space information in Management Studio

  In Enterprise Manager, the taskpad view showed me how much space is available in the data and log files. Is this information available anywhere in SSMS For instance, in one database EM shows me that I have 1200MB free in the data file and 400MB free in the log file. It also says, at the top of the taskpad view, that I have 0 free space in the database - I'm not sure how they relate, but in SSMS the only number that I can see is the 0. It also takes several mouse clicks and scrolling over to see the breakdown of the data and log sizes. OK, further research uncovered the following: http://www.sqlservercen ...Show All

• Visual C++ _tmkdir

  Can any one tell me if write permissions to the particular directory are sufficient for _tmkdir to create a new sub directory or are any higher permissions required. Thanks, KarthikR Hello KarthikR, The access rights for a directory are assigned by the administrator of the computer and generally should not be reassigned by a program. You'll note that C++ does not provide a way to alter or even read these access control lists. In order to find out what access rights you have for the folder, open up the folder's properties (in Windows Explorer) and choose the security tab, then Advanced. In this UI, the FILE_ADD_SUBDIRECT ...Show All

• .NET Development How to Modify Codebase Path for New AppDomain

  I would like to know if there is a way to change the probing directory used by the Loader to locate assembly dependencies. What I am interested in is a way to create a new Appdomain, and modify the path used by the loader to locate assembly dependencies (I would be satisfied if I could do this in the default AppDomain). The final result would be an application that hosts an appdomain (named NewAppDomain for the purpose of the illustration). The assemblies loaded in NewAppDomain would have their dependencies searched for in a specified directory, NOT the directory of the hosting application/AppDomain. I understand there may be CAS issu ...Show All
