• .NET Development Error when compiling a class that uses web services in release mode

  Here's the case (simple scenario to make things short): I have a web service that has 2 dataSets defined in it, both of them contains dataTables with the same names (myDataSet contains myDT and myDataSet2 ontains another myDT). when I create a project the references this web service, I have no problem compiling it in debug mode, but when I compile it in release mode I get the following error: Error: The top XML element 'myDTDataTable' from namespace '' references distinct types ClassLibrary1.myWS.myDataSet.myDTDataTable and ClassLibrary1.myWS.myDataSet2.myDTDataTable. Use XML attributes to specify another XML name or namespace for the elemen ...Show All

• .NET Development Could not find assembly version

  Hello, Before I start I should say I'm a .Net novice so bear with me here. And please be as basic as you can in your response :) I'm trying to run one of the sample VB.Net solutions that is provided with the latest SQL Server 2005 CTP. When I attempt to build it I get the following error: "Namespace or type specified in the project-level Imports 'System.Data' cannot be found. Make sure the namespace or type is defined and it doesn't contain other aliases" Also the following warnings: "Could not resolve this reference.

• .NET Development Assembly.Load to not throw a FileNotFoundException

  I'm trying to have Assembly.Load or LoadFrom not throw the FileNotFoundException if the assembly does not exist. Return a null maybe if possible. Using Path.FileExists is out of the question since the assembly can be in the GAC or even in HTTP (as part of a no touch deployment scenario) and I want the checking procedure to be as fast as possible. Any help is appreciated. Thanks, Kousay You can wrap your Assembly.Load call to a bindless try/catch block like this: try {  Assembly.Load("not_existing_assembly.dll"); } catch {}   Regards, -chris ...Show All

• .NET Development Delay Signing??

  Hi all, I'm wondering why should we use Delay Signing. As far i understand,Signing an assembly is required to uniquely identify it in a PC.But when we delay sign it we cant able to place it in GAC,then what is the use of it Is that same of not signing an assembly at all during development time and sign it completely using public/private keys just before deployment Also,I read in some articles that the private key should be kept very secret.Why is that Thanks, Suresh.   sureshsundar007 wrote: I'm wondering why should we use Delay Signing.

• SQL Server Why AS2005 has only Windows Authn unlike SS2005?

  Hi, I was wondering why AS2005 has only windows authentication, unlike SS2005 which has its own users and roles. What was the reasoning behind this Just trying to understand so I can explain to my peers\boss why we need to setup Windows domain users for our web-based app which has an OLAP front end.

• SQL Server Filter parameter based on prior parameter

  Hi guys, i have some report parameters that are dropdowns, and i would like to use whatever is selected in them to filter subsequent dropdowns. I know that the report designer automatically makes parameters dependant on each other, but that has been stripped out of the rdl, i need to replace it with more targeted filtering. So assuming that parameter A and parameter B get their values from a dataset, how can i filter parameter B's contents based on parameter A I am quite happy to tweak the rdl if that is what is required. Thanks, sluggy Hi Sluggy, Not sure if I've got the best answer - but I h ...Show All

• Visual Studio 2008 (Pre-release) Problem with FaultException<>

  I'm having a problem getting FaultException<> to actually return as a generic FaultException rather than the plain FaultException class. I set up a test service that can throw either a System.IO.FileNotFoundException or a System.Data.SqlClient.SqlException, with appropriate [FaultContract()] attributes on the operation. The problem is, when I throw a FaultException<FileNotFoundException> I get the correct generic exception at the client, and I can retrieve the actual exception from the Detail property. With FaultException<SqlException>, I don't get a generic exception at the client, I just get a System.ServiceModel.Fa ...Show All

• Windows Forms Datagrid goes back to default parent view when dataset refreshes

  Hi, I have a datagrid with childrows. DataGrid is bound to a dataset. Whenever I refresh the dataset using DataAdater.Fill() the datagrid goes back to its default parent view. Sometimes if a user is looking at the child rows in the datagrid and if the dataset refreshes at the same time, the child view closes down and the datagrid goes back to parent view. Is there any way I can stop this from happening so that if a user is viewing child rows in the datagrid and if dataset refreshes then it should'nt go back to the default parent view of the datagrid Thanks Hi, I am facing the same problem.
