• Visual Studio 2008 (Pre-release) Calling a WCF Service from a cluster machine which is part of NLB ...

  I have an application that hosts 2 services, service1 and service2 that is hosted in 2 machines that are part of a NLB cluster that does load balancing through muticast. If i access the services from a remote machine using the cluster IP address, it is load balanced properly. But i have a strange requirement where one of the service (Service1) needs to create instances of the other service(Service2) and want that to be load balanced. So in Service1, i created a proxy for Service2 (using svcutil) and create the Service2Client object using the cluster address as the endpoint address. In this case, even though i access the second service always using the IP address of the cluster, it is not load balanced. It always hits the same machine from ...Show All

• SQL Server Cannot set Connection property of Backup database task if connection string is customized in connection object

  I added a connection (ADO.NET) object by name testCon in the connection manager - I wanted to programmatically supply the connection string. So I used the "Expressions" property of the connection object and set the connectionstring to one DTS variable. The idea is to supply the connection string value to the variable - so that the connection object uses my connection string. Then I added a "Backup Database Task" to my package with the name BkpTask. Now whenever I try to set the connection property of BkpTask to the testCon connection object, by typing testCon, it automatically gets cleared. I am not able to set the connection value. Then after spending several hours I found that this is because I have customized t ...Show All

• Visual Studio Tools for Office Custom Task Panes in Outlook 2003

  I had been scratching my head for past few days but did not came to find any clue. I am interested in getting custom task panes to work exactly the way it works in Office 2007. Although the object model is quite dis-simmilar, yet is there any alternate way to display custom task pane or to display a user-defined windows control in an existing task pane in 2003 Any help would be appreciable. Thanks Hi Imran If I understand correctly, you're asking whether one can use VSTO to modify a built-in task pane in Word 2003 No, there is no interface to change the contents of Word 2003's built-in task panes. You can use VSTO 2.0 to create a custom taskpane for Word 2003, and that can contain a Windows form ...Show All

• Visual Studio Tools for Office VSTO SE - Create Spreadsheet on Server Without Excel

  I understand that with VSTO SE and VS 2005 you can create and manipulate spreadsheets on computers/servers that do not have Excel installed. I have done a lot of programming Excel with COM but am new to VSTO. I have searched various examples online but have not found just one simple example of creating a spreadsheet pro grammatically on a server that does not have Excel. The resultant application would be a console app that would run without a GUI to process and create/update spreadsheets. Could someone please list as briefly as possible (VB preferred, C# okay) how to create a new spreadsheet, update a couple cells, and then close the spreadsheet from the command line with no GUI.

• .NET Development CAS Policy Problem

  I have an assembly deployed which demands a certain permission. This assembly is strong named and lives in the \bin directory. To make configuration "easy", I figured I'd add a new Code Group to my Runtime Security Policy using the .NET Configuration tool which grants Full Trust to my assembly. The Code Group is under All_Code and the Membership Condition of the Code Group looks for a strong name of an assembly using the public key of the assembly (derived by importing the .dll). I disregard name and version. Straightforward, right It just doesn't work, though! Every time, my assembly fails the permission demand! In theory, it should have full trust, right What could be going wrong You ...Show All
