• .NET Development .Net 2.0 and 1.1 ???

  I am bit confused about .Net 2.0...my question is: Can i run .Net 1.1 or .Net 1.0 applications using .Net 2.0 and Can i build .Net 2.0 Applications using Visual Studio 2003 thanks Humayun Shabir SourceSystems.net Hi Humayun, in general .NET Framework 2.0 was created to extend the .NET Framework 1.1 and not to change. Although there were certain design issues that resulted in changes to be more consistent along .NET Framework as a whole. All the potential issues arising from that are here: http://search.microsoft.com/search/results.aspx st=b&na=88&View=en-us&qu=breaking+changes+1.1+2 ...Show All

• .NET Development Framework 2.0 and 1.1

  Should the system have both versions of Framework (ie. 1.1 /2.0) or its safe to remove the old one (1.1)  I know that both versions can co-exist but , why to have both, compatibilty issues I haven't seen an FAQ specific to 2.0 come out online just yet (a lot of the docs are still getting published) but I haven't heard of any reason or changes that would prevent side by side execution from working the same way as is supported for 1.1 and 1.0.  VS 2003 and VS 2005 both will continue to function as normal if installed on the same machine. http://msdn.microsoft.com/library/en-us/dnnetdep/htm ...Show All

• Visual Studio Express Editions Formless Application?

  Is there anyway to create an application that (when created) doesn't have a form For example, I would like to create an application that has an icon in the notification bar and have it so that when I double click it a settings form is created. I would prefer not to have the form exist all along and just have it invisible because to my understanding that uses more memory then creating it on demand and the goal of this application is to make it as unobtrusive as possible. Thanks in Advance, Nick Dancer. I'm not sure what this application will be doing but what you're describing sounds like a Wind ...Show All

• SQL Server Blocking Transaction

  I have a 3 simple packages get called from master package. First package populates time dimension (stored proc), second one populates transaction type dimension(stored proc) and the final one populates date dimension.

• Visual C# 'Couldn't find specified module.', 'FileNotFoundException' when declaring classdo

  When I declare a class from a referenced DLL (TrueVision3D.dll), Visual C# (2005 Express) throws a FileNotFoundException, containing the description: ' Couldn't find specified module. (Exception from HRESULT: 0x8007007E) '. The strange thing is this source code and DLL worked before, but after I reinstalled Windows XP it doesn't work anymore. All required dependencies are there in the right place -already checked that. Also: it only appears when debugging. When I run the Release executable, it just runs. Little sample code: static void Main(string[] args) { TrueVision3D.TVEngine engine; << this line throws the actual error. Sy ...Show All

• .NET Development Using TableAdapter for thousands of rows

  Hi, I have an application which needs to load about 100k of records on startup in the current design. The reason I decided to load these in a dataset rather than accessing the database directly is to speed up the user interface which now screams, but I'm faced with the issue of loading all these records at startup. Other than using Stored Procedures (which I do), what other options do I have to speed up the load process Thanks in advance, Mike Not much besides getting faster hardware and network. You can improve UI by starting separate thread and loading data in background. ...Show All
