Solution for TFS2005/2010 and VS2005/2010: Add/New Work Item menu still loading (try again in a moment)…

Posted by jpluimers on 2012/03/13

Sometimes when creating new Team work items in Visual Studio 2010 connected to Team Foundation System 2010, you get a sub menu like this:

New Work Item menu still loading... (try again in a moment)

“New Work Item menu still loading… (try again in a moment)”

There are not many results in the new work item menu still loading “try again in a moment” site:microsoft.com query, but luckily the first one shows a similar issue in Visual Studio 2005 with Team Foundation System 2005: the “Add Work Item menu still loading… (try again in a moment)”.

The solution is also very simple:

  1. Quit Visual Studio 2010
  2. Delete this registry key
    HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\10.0\WorkItemTracking\TeamMenu\AddWorkItemMru
  3. Start Visual Studio 2010
  4. Retry (can take more than a minute, but it usually works)
The only difference between the Visual Studio 2010 (version 10.0) and Visual Studio 2005 (version 8.0) is the version number:
  • HKEY_CURRENT_USER\Software\Microsoft\VisualStudio\8.0\WorkItemTracking\TeamMenu\AddWorkItemMru

Not sure if this can fail in Visual Studio 2008 too, but if it does, just apply this fix with version number to 9.0, and if it happens with the Visual Studio 11 developer preview, change the version number to 11.0.

How to install Windows 7 on a virtual hard disk (VHD) in 10 steps (via: Guides & Tutorials)

Posted by jpluimers on 2012/03/12

Handy when working with Microsoft Surface: install your development environment on a separate VHD that you can boot as your physical machine (Microsoft Surface SDK does not like being run in a Virtual Machine):

If you accept the constraints described above, I propose the following procedure, which I think is the easiest way to install Windows 7 on a virtual disk in multi-boot

Note: Within the VHD you can still access all the files on your physical HD.

“Cannot navigate to definition” annoyance in Visual Studio 2010 – (did it implement the mouse equivalent to Delphi code browsing? No, it didn’t)

Posted by jpluimers on 2012/03/08

This use case drove me nuts in Visual Studio 2010 for a while, but can be solved.

Use cases:

  1. Cannot navigate to definition.double click on a word to select it
  2. press Ctrl-C to copy the selected text
  3. result is either of these two dialogs:

    ---------------------------
    Microsoft Visual Studio
    ---------------------------
    Cannot navigate to definition.
    ---------------------------
    OK
    ---------------------------

    Cannot navigate to definition. The cursor is not on a symbol.or

    ---------------------------
    Microsoft Visual Studio
    ---------------------------
    Cannot navigate to definition. The cursor is not on a symbol.
    ---------------------------
    OK
    ---------------------------

The reason is that Visual Studio 2010 still thinks I am clicking the identifier (which I’m not, I just released the mouse button) while pressing the Ctrl key. Read the rest of this entry »

Eric Lippert’s comment and answer explaining nullable operator lifting (c# – Why does the == operator work for Nullable when == is not defined? – Stack Overflow)

Posted by jpluimers on 2012/03/07

It seems I’m not the ony one who watches what Eric Lippert writes closely.

Eric works at the C# team at Microsoft (since 1996, which is about the time Anders Hejlsberg joined Microsoft).

Unlike Anders, Eric is much more visible. I regularly read his blog, and watch his StackOverflow.com contributions (RSS feed) on a regular base.

Recently, he posted a awesome comment “Nullable is nothing but magic” on a the question “C# – Why does the == operator work for Nullable when == is not defined?“, together with a very concise answer explaining that in C# most operators are ‘lifted to nullable’.

Note his tiny – but important – mention that for == VB.net behaves different than C#.

Note that Eric is very productive, he usually contributes to StackOverflow.com multiple times a day, sometimes with material that (at least for me <g>) need a while before I really get the point.

Recommended reading :)

Anyone with a C#, Delphi or FreePascal implementation of the PRESENT Ultra-Lightweight Block Cipher encryption?

Posted by jpluimers on 2012/03/06

A short while ago a paper got published on PRESENT: An Ultra-Lightweight Block Cipher by Andrey Bogdanov et al becoming ISO standard 29192-2:2012.

Is there anyone that has a C#, Delphi or FreePascal implementation with unit tests?

Windows 8 Consumer Preview ISO formats: Microsoft, please do this the same for Visual Studio 11 (#VS11 #W8)

Posted by jpluimers on 2012/03/02

Hopefully they will add Visual Studio 2011 ISOs (no, not the current ones that still download the prerequisites in the background) like they did with the Windows 8 Consumer Preview ISOs:

Solution for Visual Studio 2010 VB.NET errors “Type ‘MyProject.My.MySettings’ is not defined.” and “MyProject’ is not a member of [Defalut]” #VS2010

Posted by jpluimers on 2012/02/29

(Note the WordPress bug: you cannot have <Default> in a topic title, but having it in the text is fine, hence the [Default] in the title).

When porting some projects from .NET 1.x to .NET 4.x, I got these two errors:

Error 17 Type 'MyProject.My.MySettings' is not defined.
Error 18 'MyProject' is not a member of '<Default>'.

Both errors in the file ...\My Project\Settings.Designer.vb relative to the MyProject.vbproj file.

This was not the result of something like this Visual Studio 2005 bug, but of how the designer generated files are not being regenerated when you change the root namespace only in the MyProject.vbproj file, not through the IDE.

Steps to reproduce:

  1. Create a MyProject class library in VB.NET
  2. In the MyProject.vbproj, change the RootNameSpace into MyNameSpace.MyProject.vbproj
  3. Build

Lesson learned: when using text compare tools, some .vbproj changes should be propagated through the IDE, not through your favourite text compare tool.

When you change it in the IDE, it regenerates the *.Designer.vb files to reflect the changed namespace.

The solution is simple, in the IDE follow these steps:

  1. In the Project Options change the RootNameSpace to a dummy
  2. Build your project
  3. Chante the RootNameSpace to what you want
  4. Build your project

P/Invoke: usually you need CharSet.Auto (via: .NET Column: Calling Win32 DLLs in C# with P/Invoke)

Posted by jpluimers on 2012/02/28

I don’t do P/Invoke often, and somehow I have trouble remembering the value of CharSet to pass with DllImport.

In short, pass CharSet.Auto unless you P/Invoke a function that is specific to CharSet.Ansi or CharSet.Unicode. The default is CharSet.Ansi, which you usually don’t want:

when Char or String data is part of the equation, set the CharSet property to CharSet.Auto. This causes the CLR to use the appropriate character set based on the host OS. If you don’t explicitly set the CharSet property, then its default is CharSet.Ansi. This default is unfortunate because it negatively affects the performance of text parameter marshaling for interop calls made on Windows 2000, Windows XP, and Windows NT®.

The only time you should explicitly select a CharSet value of CharSet.Ansi or CharSet.Unicode, rather than going with CharSet.Auto, is when you are explicitly naming an exported function that is specific to one or the other of the two flavors of Win32 OS. An example of this is the ReadDirectoryChangesW API function, which exists only in Windows NT-based operating systems and supports Unicode only; in this case you should use CharSet.Unicode explicitly.

SQL Server 2000: How do I register multiple databases with Microsoft SQL Server Enterprise Manager?

Posted by jpluimers on 2012/02/24

I’m in the midst of a big migration traject.

One class of systems involved in the migration is SQL Server 2000 databases (yes, I know that SQL Server 2000 has been in Extended Support mode since April 8, 2008, that’s one of the grounds for migration).

Sometimes, you need SQL Server Enterprise Manager (a plugin to the Microsoft Management Console) to work on those databases to see what needs to be migrated (yes, this should be in the documentation, of which the ultimate form is the system itself ;-).

SQL Server Enterprise Manager has a nice feature that you can group SQL Server registration into SQL Server Groups.

However, it also has a limitation: you cannot add the same SQL Server to multiple SQL Server Groups. That is: unless you create an alias on the SQL Server, as aliases are not counted in the “unique” criterion.

Below are the top 2 links I found using “multiple databases” “sql server”  “enterprise manager”. Since I’m not sure the content of those will last, below are the full quotes.

Besides adding a SQL Server Alias (which has other uses as well), the most important steps are “6” in the first quote, and “1.6” in the second quote: your alias needs to point to the same IP address (or hostname) as your regular server.

How do I register multiple databases with MS SQL Enterprise Manager?

MS Enterprise Manager does not allow you to register the same database server multiple times. It is sometimes useful to create multiple registrations, if you want to connect to different databases on the same server. To workaround this, follow the steps below.

  1. Go to Start – Programs – Microsoft SQL Server – Select “SQL Server Client Network Utility”
  2. Go to Alias Tab
  3. Click “Add”
  4. In the “Server alias:” text box, enter a name you want to use to distinguish this database server
  5. In the “Network libraries:” section, select “TCP/IP”
  6. In the “Connection parameters” section, change the “Server name:” to your database server, i.e.; mssql01.discountasp.net
  7. Click OK

Once the Alias is created, you can register it using the same method described in this Knowledge Base article.

How can I open multiple databases in SQL Server Enterprise Manager?

  1. Create SQL Server Alias
    (Please repeat the following steps if you want to open mutiple databases)

    1. Open SQL Server Client Network Utility.
    2. When Client Network Utility opens, click on the Alias tab.
    3. Click on the Add button.
    4. In the Server Alias text box enter a name for your SQL connection.
    5. Select TCP/IP under Network libraries
    6. Enter the IP address of the Server your SQL database is located on, in the Server name text box.
    7. Click on the OK button.
    8. Your Server alias will now be configured, click on the Apply button.
    9. Click on the OK button.
  2. Create SQL Server Connection in Enterprise Manager
    (Please repeat following  steps if you want to open mutiple databases)

    1. Open SQL Server Enterprise Manager.
    2. When Enterprise Manager opens, right click SQL Server Group and select New SQL Server Registration.
    3. The Register SQL Server wizard will now open.
    4. Click on the Next button.
    5. From the Available Servers drop down menu, select the server alias you created earlier.
    6. Click on the Add button.
    7. The server should now be listed under Added servers, click on the Next button.
    8. When the next dialog box appears select The SQL Server login information that was assigned to me by the system administrator see above.
    9. Click on the Next button.
    10. Enter your Login name and Password ? this will be used every time you connect to your SQL server.
    11. Click on the Next button.
    12. Ensure that Add the SQL Servers to an existing SQL Server group is selected and SQL Server Group is selected for Group name.
    13. Click on the Next button.
    14. When the next dialog box opens you can click on the Finish button.
    15. Your SQL Connection will now be created.
