• SQL Server SQL Client Redirect - Database Mirroring

  Hi All, My apologies if this question seems abit basic, but I'm a DBA by trade and programming .Net isn't my strong point ;) I've enabled database mirroring on 3 SQL 2005 servers, a principal, a mirror and a witness. Principal - SQL 2005 Enterprise Edition, SP1 Mirror - SQL 2005 Enterprise Edition, SP1 Witness - SQL 2005 Express, SP1 I've written some test code to test the mirroring but as soon as the connection is pulled from the principal, the client re-direct doesn't work and the program bombs. I'd be grateful fi someone could have a look at my code below and tell me if there's any schoolboy errors (NB, the user running the code is a sys admin on all 3 servers) Thanks in advance.

• .NET Development Deleting a single row from related tables

  Hi, I have 3 related tables. First one is the parent and the other two are children of the first one. Ican navigate through parent and its children using DataGridViews and relations. When I delete a single row from my parent table I want to delete only its children not all the deleted rows in child tables. When I use DataTable.GetChanges() and try to iterate through its rows checking if the row's foreign key matches to the parent row's primary key I have an exception saying "you can not access a property of any 'deleted' row" which forces me to delete all deleted rows from each child table. How can I get the deleted rows that belong to my parent row Thanks for any help. Not a professional solution but I must agr ...Show All

• SQL Server MDX: Percentage-to-totals with subcubes (AW code sample)

  I need to create a calculation that gives me the percentage of a members value relative to the total. My problem is that I cannot make it work when my query is using a subcube in the from clause. The calculated member is simply not able to look outside the defined subcube. In other words - the following query works as expected: WITH MEMBER [Measures].[Test] AS [Measures].[Internet Sales Amount]/( ROOT ([Product]),[Measures].[Internet Sales Amount]), NON_EMPTY_BEHAVIOR = [Measures].[Internet Sales Amount], FORMAT_STRING = "#.##" SELECT {[Measures].[Internet Sales Amount], [Measures].[Test]} ON 0, NON EMPTY [Product].[Subcategory].

• SQL Server SSAS Cube and Report Model

  After creating a cube in SSAS, is it possible to make this visible to users in Report Builder As far as I can see Report Builder uses report models which are based on a relational database for a data source view, so it seems I have to rewrite all the cube logic in order to make it available in Report Builder (otherwise I guess it's a case of telling users to connect to the Cube from Excel ) Thanks Not sure this answer your question or not. Once you deploy and process your cube go to SQL Server Management Studio, connect to Reporting Services.

• Visual Studio Express Editions Going back to Originating Form

  Okay, This may seem like a newbie question, and it probable is.  How does one go back to an originating form when the originating form could be one of many, many options.   So for example: You have twelve forms.  Each named (for simplicity sakes) Form1 through Form12.  Form1 can take you to each of the twelve forms. Forms 2-5 can take you forms 6-12. Forms 6-8 can take you forms 1, 2-5, 9-12 or they make go back to themselves (From Form 6 to Form 8 and vice versa) Forms 9-12 can take you 1, 2-5, 6-8 or they make go back to themselves (From Form 9 to Form 12 and vice versa) All Forms can always go back to Form 1 (which easy enough) But if I am on Form 9 and I want to go back to 5 (an orginating For ...Show All

• .NET Development errors adding a web service with sockets to a C++ project

  Hi everyone, I have a web service which communicates via TCP to a C# program. When I invoke it's methods through a browser, they work fine and can communicate perfectly with the C# program. However, when I attempt to add the web service to a C++ MFC DLL I've created, I get multiple warnings, but with only 2 unique: 1) Warning 3 warning SDL4008 : skipping unrecognized extensibility element, with c:\Documents and Settings\*******\My Documents\Visual Studio 2005\Projects\Extend\Extend\CalcSvc\CalcWS.wsdl 84 2) Warning 9 warning SDL4001 : only one SOAP port will be processed. c:\Documents and Settings\cpappas\My Documents\Visual Studio 2005\Projects\Extend\Extend\CalcSvc\CalcWS.wsdl 104 I am assuming it is because the web service opens a s ...Show All

• Windows Forms Closing Managed Form Hides the Unmanaged Owner

  Hi, Just wondering if anyone has seen this problem. Situation: I have an unmanaged app from which I'm using C++/CLI to instantiate a managed modeless dialog. I pass in the unmanaged Handle in the Show call (via a IWin32Window wrapper) to make the unmanaged app main window the owner of the managed form. This works fine in most situations. However, and here's the crux, if my managed form itself launches a modeless or modal dialog, then whenever I choose to close the original managed dialog, regardless of whether the child dialog has been closed or not, then the unmanaged app disappears . It either gets sent to the back or minimized, but the point is that it is no longer the top window. The application is fine, and clicking on the ...Show All

• Visual C# Cloning - include event handlers

  Hi there: I need to create at runtime an exact copy of one of the objects I'm using, so I created a "Clone" method for it -- same as other clone methods: NewObject newObject = oldObject.Clone(); Now, to copy property values I either have to code every single newObject.Property = oldObject.Property; or use reflection (GetType, GetProperties and loop). Either way is fine, the bit of a block comes when I also try to "copy" the event handlers: let's assume my oldObject implements a "clicked" event. When I create oldObject I add the event handler for the clicked event: this .oldObject.clicked += new EventHandler (myClickedHandler); What I want is newObject (the object that is clone ...Show All

• .NET Development Internal vs. Public

  Sorry if this is simplistic, but is it a viable design choice to restrict visibility of as many type members as possible in a Windows application exe to internal, rather than public This client will necessarily never be consumed by any other class or application. It also suppresses various VS warnings about uncommented members, which are irrelevant anyway in many cases. Thoughts, comments Hello All. nobugz: Sorry, I wasn't trying to go off-topic. I thought the question was pertinent to this: nobugz said: Hmm, I don't think it really matters when these are classes in a .exe. Although it is technically possible for another app to load the assembly for an .exe, this is rarely if ever do ...Show All
