• Visual Studio Express Editions 8007007B failure when creating first application

  The good person at my customer site who has to decide after the first of the year which edition of VS 2005 to buy (I'm urging the MSDN subscription route) wanted to play over the holidays so he could get a feel for it. He is running an up to date XP SP 2 system. He has had the same behavior with both VB Express and VS 2005 Standard Edition. When he tries to creat a new windows application he gets an 0x800700B (File name... syntax is incorrect) error after clicking on windows application. The project is created but the form is not. I cannot reproduce this in my environment with standard edition. He has done the limited thin ...Show All

• Visual Studio 2008 (Pre-release) DLinq and null values and defaults

  Is there any way to specify how DLinq handles null values - for example: [Table] public class Thing { string name; [Column] public string Name { get { return name; } set { name = value; } } } CREATE TABLE Thing ( Name NVARCHAR(120) NOT NULL CONSTRAINT DF_Thing_Name DEFAULT(N'No Name') ) ... results in an INSERT command that specifies NULL for [Name] when it would be helpful to indicate DEFAULT. Using stored procedures will handle it, but something like [Column(NullValueUpdate = NullValueUpdate.SetDefault)] would be handy... Thanks. Looking a bit further, it appears that ...Show All

• .NET Development System.Threading.Monitor.Enter (under the hood)

  What do the threads that are locked out do when they are locked out And does the Sleep call help get { if(dsUsers == null) { if(IsdsUsersLocked) System.Threading.Thread.Sleep(50); lock(UsersPadlock) { if(dsUsers == null) { IsdsUsersLocked = true; dsUsers = (3 sec call to the database server accross heavy network traffic); IsdsUsersLocked = false; } } } return dsUsers; } The sleep call appears to help when dealing with 100 or more threads but i don't know what really happends to the thread that are locked out.

• Visual C++ VS2003 to VS2005: locked files, cannot build

  Hello, We have a large C++ product consisting of about 40 components (COM and otherwise) as projects in a single VS2003 solution. I am now trying to make it compile under VS2005. The problem is that VS2005 locks one of the generated TLB files and does not allow me to modify it, so I cannot build (or even "clean") this component and a large number of components that depend on it. Process Explorer shows that the file is held by "devenv.exe". The only way to "release" the locked file is to exit Visual Studio but this is no way to develop... I suspect intellisense but there may be a different reason. ...Show All

• SQL Server How to change data Dynamically in report services

  Hi, Please help me. I created a report and works fine but I am wondering  how to change  data dynamically. For example I have different data base and want to run the same report in different places I can't go and change the report each time. Any suggestion please Thanks in advance. You should change the query so that instead of returning one column per day you "denormalize" it to return one day per row: Day Count ----- -------- Mon 2 Tue 2 Wed 4 ... In the report, you could then just group by the Day field (in a matrix), or use conditional aggregation if you choose a table ...Show All

• Visual Studio Designer Issues

  Hi Jon, We are glad you like the Class Designer. You can create a custom collection class that inherits from the collection class by doing the following: Go to class view. In the search control, type in the name of the base collection class you want to inherit from (make sure your project has a reference to the assembly containing the definition of the collection class).  For example, ArrayList. You will see all the classes containing the string expression ArrayList. Drag and drop the one you want to inherit from into your class diagram. Go to Toolbox (available from the View menu). Drag and drop a class.  Speci ...Show All

• .NET Development WSE 3.0 - PolicyAssertion and Attachments

  Hello, I'm starting using WSE 3.0 and I'm having trouble in finding solution to these 2 problems: - I have created a PolicyAssertion and I want my WebService to use it without using a policy file. I've managed to do this on the client side, but on the service side I'm out of ideas. The documentation on the subject only gives examples with a policy file, but I wanted to do this without one. - In WSE 2.0 we had SoapEnvelope.Context.Attachments where I would put binary attachments. In WSE 3.0, can we just add binary data to the body Thanks in advance for any help given. Regards, paulo Hello Mark, It works ...Show All
