• .NET Development Generic Design-Time Environment Features

  Hi all, I am developing a suite of .NET non-visual components with design-time capabilities. They will be used mainly in Visual Studio 2005, but I would like them to work in any IDE supporting .NET Framework 2.0 development. So I would like to understand what is the behavior of a "generic" design-time environment, which can be expected by a Component and its Designer, Type Converter and so on. It seems obvious that it must provide the IDesignerHost interface, and can provide many other Services. But it is not clear which Services are mandatory, recommended or optional. I see that Visual Studio implements all Design-Time Servic ...Show All

• SQL Server Need a function to return a comma delimited string from multiple columns and rows

  Columns in a rows are ClaimID,LineNo, Code1, Code2, Code3, Code4 A claim id can have multiple detail lines. I want to return a comma delimited string for all the codes found for a claim id.

How do I loop thru a table similar to this While Table.claimid = @ClaimID Set @MyString += Code1 +"," + Code2 + "," + Code3 + Code4 Loop   You do not need a UDF to generate the CSV string.

• .NET Development Help! C# program died quietly!

  The program was written with VB6 and C# (.Net 1.1). The dll written with C# is responsible to the real time communication with the industrial devices. It contains a few threads, some of which continuously poll the devices for the real time data. It exposes the COM interface (methods and events) to VB6 part. Most time the system can run smoothly without any problem. But sometime, after running for a while, the program just died QUIETLY. There is no any error information logged in system event log and no error reported to user. The time it takes could be a few minutes, a few hours or two or three days. In addition, I have ...Show All

• Visual Basic Issuer Certificate

  I’m getting the " The issuer of this certificate could not be found. " error, My certificate says "Issue by Thawte Code Signing CA", Do this means that I have to get under Trusted Root Certification Authorities a Certificate that says "Issued To Thawte Code Signing CA" Thanks a lot. Under what circumstances are you using this certificate Assembly Signing or Publishing For Click Once Manifest Signing, the certificate will need to be verificable and so if you don't have the parent certificant from the issuer in your store then that is the most likely culprit.

  How do you Multithread in VBA for Excel I know how to do it in Visual Basic Studio but I cant get it to work for Excel Is there a certain reference I need There is very limited information on the web about multithreading in Excel.  The web also says Excel Visual Basic 6.3 has multithreading capabilities.

• .NET Development Dataset serialization

  I have an issue with the Dataset serialization. I have a class, say BaseDataSet which inherits from the Dataset. More classes inherit from BaseDataSet. I would like to pass on the object inherited from the BaseDataSet back to the client via a web service. Before passing on I cast the derived object to BaseDataSet type. On the client, I am not able to down cast the dataset back to the specific class which is the type of dataset passed across. Are you applying the serializable attribute to all your descendents [ Serializable ] public class BaseDataSet : System.Data. DataSet { } [ ...Show All

• SQL Server Number Format

  Hi all, I have developed a report in which I need the thousand seperator to be a decimal point. Instead of presenting the number as 12,923.23 i require that the representation be 12.923,23. I have tried to customize the the format with the hash value but have had no joy. Any help would be much appreciated. Ivan Here's one way to do it. Also if this will be done on the fly, it probably will work best as a user-defined function. You could also nest all of the replace functions for a single select for production, but I did it this way to be more readable. declare @test money Set @test = ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Linker errors

  In our game engine the audio and the scripting system are plugins so I have created an XACT audio plugin for our engine. The problem is that some parts of the scripting system plugin includes xact.h because it needs access to some of the xact structures, but this causes linker errors for the scripting system because xact.h contains a macro that uses CoCreateInstance. Would it be possible to have #ifdef NOMACROS around the macros so they can be easily disabled. Best regards Steen L. Nielsen www.flux-studios.com Hi Steen. Just so I understand the problem exactly: Your engine doesn't l ...Show All

• Visual Studio Express Editions Dumb newbie question regarding XP Styles

  Going through the video tutorials which show forms with XP style borders, etc.  However, mimicking those actions of the trainer, I only see plain vanilla-styled form headers and such.  I understand there's a way to "fix" this, but I don't know how.  Any referral links   Note that I have Visual Basic Express on an XP Tablet edition machine. BTW - Microsoft - why aren't XP styles the default for this new version of Visual Studio Tom Try the following: 1. In Solution Explorer , right-click on your application and choose Properties 2. In the Properties window, choose the Application ...Show All
