• Visual Studio Tools for Office Outlook Addin Deployment Strategy

  We're writing a ClickOnce smart client app, which will have an Outlook addin component. The publish mechanism will maintain the smart client app. We're looking for the best Outlook addin deployment strategy to complement ClickOnce. We want to maintain the addin seamlessly. The problem I'm seeing is that the addin "Publish" option does not handle registry entries or CAS. There's a theory that we can bundle deployment-aware publish manifests into a setup project. Then the setup would make the initiail registry and CAS entries, while the manifest system would maintain the code from that point forward. But this seems limited to only those upgrades that don't require registry or CAS changes. So, if you make a change that affects ...Show All

• SQL Server “AcquireConnection method call to the OLEDB Connection Manager for SQL Server failed” Error

  I have an SSIS package which takes input from Flat file and transfer the data to SQL Server using OLEDB Destination Data Flow Item. The OLEDB Connection Manager used for the destination is configured to use SQL Server Authentication for the user ‘sa’. The package works fine without enabling the configurations. But when I enable package configuration and save the configuration of the various connection managers in an XML configuration file and then run the package it gives the following error in the validation phase: [OLE DB Destination [21]] Error: The AcquireConnection method call to the connection manager "<Connection Manager Name>" failed with error code 0xC0202009.

• Software Development for Windows Vista DelayActivity, State-Machine Workflow, Sharepoint

  Hi there! We've got a problem with a state machine workflow in sharepoint 2007, especially with the delay activity. It seems to me as if the event of the timeout is generated, but not executed. My workflow is quite simple. It only has three states, Start, Execute and Completed. I create a task in the Start State and step to Execute State. This one has two EventDrivenActivities. First a OnTaskChanged an second a Delay (20 sec). If I install my workflow to a document library in sharepoint, start it an finish the task within 20 sec (debug mode VS2005) nothing surprising happens. The Code in the OnTaskChanges branch is executed as it should be. If I wait my 20sec without working on the task, the code of the Delay branch should be executed, but ...Show All

• Windows Forms OnHandleCreated, IsHandleCreated: some threading issue makes me crazy :(

  I'm getting smth strange. I am overriding OnHandleCreated method on my Form, and as usual Window Handle is already created i can happily access it from the OnHandleCreated method body. but if start a new thread right away, i can not access the Window  Handle from there - at least "IsHandleCreated" returns false and Form.Invoke methods throws an exception if called from this new thread "private IntPtr handle;" is not declares as volatile, so maybe what i am getting is a threading memory synchronization issue how do flush thread caches i've tried executing some "locked" section - in Java this would reload all the data from the main memory copy, but this did not help :( what i hate about my problem - it is 50% repro ...Show All

• Windows Forms Does WinForms 2.0 support floating and docking menu/toolstrips like Office 2003 or Visual Studio 2005? [Question only for MSFT]

  I had high hopes for the ToolStripContainer but it appears that it only allows a ToolStrip or MenuStrip to be moved from one of its edges to another. If I start dragging a ToolStrip and try to release it anywhere except one of the four edges—for example, in the content panel or outside the window—nothing happens. Question: Is there some existing mechanism that I can use or is it necessary to build this from scratch I know about third party controls, but I'm looking for standard solution (in WinForms 2.0 from Microsoft)! PS: My question is only for MSFT! ...Show All

• Visual Studio Help System, Sandcastle - Catch 22's, etc

  Hi, I've downloaded and installed Sandcastle, I've downloaded and installed Eric Woodruff's Sandcastle Builder and I've downloaded Innovasys' Document X product. Both Eric's the Innovasys' software inform me that I need to install the Help System, I'm not certain that Sandcastle itself didn't tell me the same thing. So I downloaded the Help System, however early on in its install process I was informed that I already had the help System installed and because it was a later version and because it wasn't broken the install, of the version I downloaded on Tuesday, terminated. I've installed the May MSDN in its entirety and I have VS Express (C# and J#) installed. Any suggestions, other than reformatting my disks and reinstalling everything (I ...Show All

• .NET Development Data Adapters...where are they?

  I just upgraded to VS2005 and am just wondering what the differences are between the data access setups. I know that in my current code from previous projects I have data adapters and I see that the VS2005 doesn't even have data adapters. The reason I'm asking.... I was working with a project and I needed to add another connection/data adapter and I couldn't. So, I just copied and pasted a previous one and set the properties like I wanted. This didn't work and only made it so none of my connections/adapters are working now. It was odd, but would it be worth my time to just switch over to the newer style Thanks for your time. I found it odd myself. Is this the way I should have gone about adding a new d ...Show All
