Multiple SQL Server installations on different machines vs multiple instances

Hi,

I've created simple sequential workflow. It's only creates one task and is waiting in while loop until task is Approved. It works fine when I run only one instance of this workflow, but if I start another instance before first one is finished it gets stack and doesn't complete task an workflow stays in In Progress state forever.

I will appreciate it if someone can help me to undestand how the following scenario works:   There is remoting server that is registered as WellKnownObjectMode.Singleton. Server implementation: It instantiates a class TestServer that implements interface IFoo interface IFoo { IHelper GetHelper() }   interface IHelper { void StoreString(); }   Implementation of TestServer: internal sealed class TestServer: System.MarshalByRefObject, IFoo { private IHelper> helper = new Helper(); public IHelper GetHelper(string helper){return helper;} }   Implementation of Helper: internal sealed class Helper : System.MarshalByRefObject, IHelper { public void StoreString (string val) {}; }   Implementation of a client (simplified; shown to illustrate the question only): static class Program { public static IFoo TestService; public static IHelper Helper; public TestThreads testmultiplecalls; [STAThread] static void Main() { TestService = (IFoo)Activator.GetObject(typeof(IFoo),"ipc://Channel"); Helper = TestService.GetHelper(); testmultiplecalls.Start(); } }   internal class TestThreads { public Start() { for (int i = 0; i < 20; i++) ThreadPool.QueueUserWorkItem((new TestCall(i.ToString())).DoWork); } }     internal class TestCall { private string m_str; public TestCall (string str) {m_str = str;} public void DoWork() { Program.Helper.StoreString(m_str); } }     Que

Hi, The server sends event to multiple clients; It goes through a list of callback destination clients and sends one by one. My question is, if one client down or in dead loop processing the event, does it affect all the other clients to receive event? Is it the same if I use HTTP or name pipe? The code is like that: for each (callback^ cb in registeredCallbacks) { cbClient = getClient(cb); if (cbClient) { try { cbClient->sendEvent(data); } catch (Exception^ ex) { deregisterCallback(cb, ex) } }   I wonder if one client fails, would it affect all the others. Thanks in advance Simon

Hello. I am familiar with classic ASP and use this with MS SQL SERVER EXPRESS. I have an SQL table and want to import multiple XML files into this on a daily basis. I currently have 3 files, transferdata.vbs which loops through the XML files. FAQschema.xml which maps XML to the SQL database and test.xml shows the xml in the test file. If I run transferdata.vbs I get the following error "Error opening the data file" line 33 char 3. Microsoft Bulkload for SQL Server". My SQL table is called EnqOrd id (int), Debitor (varchar), PurchaseDate (varchar)     transferdata.vbs set objBL = CreateObject("SQLXMLBulkLoad.SQLXMLBulkLoad") objBL.ConnectionString = "Provider=SQLOLEDB; Data Source=XXXXXX\XXXXX; Initial Catalog=XXXX; User ID=XXXXX; Password=XXXXXX" objBL.ErrorLogFile = "E:\fuelsql\Teccom\error.log" ' Here is the path to your XML files Const path = "E:\fuelsql\Teccom\XML\" Dim Text, Title, oFile Dim fso, oFolder, oFiles, wsh ' Object variables Text = "Folder " Title = "XML Files" Set wsh = WScript.CreateObject("WScript.Shell") ' Create FileSystemObject object to access the file system. Set fso = CreateObject("Scripting.FileSystemObject") ' Get Folder object. Set oFolder = fso.GetFolder(wsh.ExpandEnvironmentStrings(path)) ' Get All Files Set oFiles = oFolder.

Hello, I want multiple users to access same report or different reports through report manager for a report server. Will the scenario of opening multiple windows of report manager on same machine and execute reports from all windows simultaneously mean same as multiple users accessing the reports at the same time?

Hi,   I have set of database backups created in the production sql server 2005. I need restore these backups into another sql server 2005 by using t-sql script(stored procedure). Each database will have different number of logical files in it. The physical location of the target server may be different for these logical files. I know that i should use WITH MOVE 'YourMDFLogicalName' TO 'D:DataYourMDFFile.mdf' clause. Now i want to know how would i put it in a t-script stored procedure such a way that it automatically identifies all the logical files and create a physical file on the target server. User will supply source of bakup file and target folder for mdf,ldf, etc files. Do i need to populate the sql query as string by looping through all the logical files? If so how would i execute the populated sql query as string ?  Mr Genius

How to use single windows service to host multiple WCF Services. I have a mutiple instance of same WCF service in different folder, each instance has unique service name and port. WCFService has reference to Reg-Free COM Reference, i have Native.WCFService.manifest in each folder. Ex: WCFService1 is in "C:\WCFService01\WCFService.dll, Native.OCWCFService.manifest, OCWCFService.dll.config WCFService2 is in "C:\WCFService02\WCFService.dll, Native.OCWCFService.manifest, OCWCFService.dll.config Now i need host above services from single Windows Service. I am trying to create AppDomain for each above WCFService Instance from Windows Service and then host. Its working if i register COM dll in the server using regsvr32, but when i un register COM dll, i am getting unable to load COM component .... This looks like AppDomain is not loading COM DLL and Manifest files. Its looks strange but we need it in this way because we have production and test environment in the same server. Everything works fine if create a seperate Windows Service for each WCFService Instance, but my manager wants single Windows Service :). Any help whould be really appreciated.  ravi kumar reddy

I have an ASP.NET page inside of an ASP.NET Master page, and inside the page I have two instances of the same web user control. I have given them different IDs, but when I click a button on the first user control it causes the second user control to do the expected activity and the first one does nothing. Is there something I need to do to make sure that the controls don't get confused? P.S. The expected activity is that when the button is clicked one panel object is disabled and another is shown. When the button is clicked on custom control 1 the panel on custom control 2 is disabled and it's next panel is shown and custom control 1 does nothing. Thanks for the help.
