• Visual Studio 2008 (Pre-release) Implicit parameters in lambda expressions

  Consider v.FindAll(x => x > 5) We could use an implicit parameter in order to supress the parameter list. So we need a keyword to refer to the undeclared parameter, for instance "it" or "_1". The previous code would be equivalent to: v.FindAll( => it > 5) or mayby: v.FindAll( it > 5) For an unnamed second parameter we could use it2 or _2 etc. Is there any problem with this new simplification   Potentially variable name collision (this is why "yield" is not a keyword) ambiguity between immediate expression "it > 5" and proposed lambda expression "it > 5" In general, I think ...Show All

• SQL Server General Network error

  I am using Windows Form with web service, I am getting error ocassionally when I am accessing records " System.data.sqlclient.sqlexception General Network error " , When I click again the error disappears.

• SQL Server RS 2005 connecting to Clustered sql 2000 server

  We have a configured environment where we have sql 2000 in an active passive cluster.  I have a seperate machine where I installed RS2005 and store the RS database on the SQL 2000 Server.  When doing this, I get errors with WMI. Although saving the database connection succeeded, the report server cannot access internal information about this deployment to determine whether the current configuration is valid for this edition.  If you are configuring scale-out deployment, be sure that you initialize any new report servers from one that is already part of the deployment.

• Windows Forms How can I create an MDI child form?

  Is there anyone who could explain for me how can I create an MDI child form Regards Hi, I'm sorry for the delay of response. I've been having a break. Sorry again but its no possible. A little bit of programming is involved when you create a Mdi-child form. But I think its quite similar to the VB6 approach. You'll just have to set the MdiParent to the instance of the MDI form upon showing. In VB6 you'll just create a form and change its MdiChild property to true. Its still the same in .Net but you'll just specify the MDIParent in Code... cheers, Paul June A. Domag ...Show All

• Visual Studio Team System Workspace folder mapping bug?

  I have a directory at C:\Projects\Foo\Src\Runtime\EncryptionLib\UnitTests that I branched to location $/Foo/Branches/Developer/hillr/Exp_UnitTests.  I then try to cloak $/Foo/Src/Runtime/EncryptionLib/UnitTest and then map $/Foo/Branches/Developer/hillr/Exp_UnitTests/UnitTests to C:\Project\Foo\Src\Runtime\EncryptionLib\UnitTests.  VSTS gets confused.  When I edit files in the UnitTests dir in this worksapce they are really being edited on the trunk instead of my private branch.  When I go back to the Workspace mapping it has removed the two lines I added and put in: active $/Foo/Src/Runtime/EncryptionLib & ...Show All

• Visual Studio per user variation for build

  In microsoft.common.targets I found the following construct: <Import Project="$(MSBuildProjectFullPath).user" Condition="Exists('$(MSBuildProjectFullPath).user')"/> This made me assume that I can put a [csprojfile].user file in the folder where my csharp project file is located and then override common targets (like BeforeCompile) Unfortenately I don't get this scenario to work. Question: Is my assumption correct (assumptions are the mother of all ****-ups) and if so, why is msbuild not calling the targets in the .user file Tnx, Rene Ok, that make sense. I thought of it as an way of building/compiling ...Show All
