• Architecture Layered Architecture across Boundaries

  Hi, I would like to know, how separating layered architecture across boundaries can increase performance and scalability. We have a scenario where client insists on the Presentation Layer on a separate machine and the application server on a separate machine and the interaction between them is going to be using Web Services. Web Services are arguably slow and how can the performance improve against having the UI Layer and Business Layer in the same box. Thanks. When it comes to distribution, performance is seldom the top reason for why you would want to distribute. In many cases perfo ...Show All

• Smart Device Development LoadToolBar/InsertMenuBar

  I'm having a little trouble with menu/toolbars in an application ported from EVC. Apparently, I'm not the first. None of the threads so far seem to address the specific issue I'm dealing with (or I haven't read them closely enough to understand how they might), which is as follows: In my CMainFrame::OnCreate() I'm doing the expected creation and initialization of a CCommandBar (formerly CCeCommandBar): if (CFrameWnd::OnCreate(lpCreateStruct) == -1) return -1; LPCTSTR resource = MAKEINTRESOURCE(CAppPreferences::IsHighDpi() IDR_MAINFRAME3 : IDR_MAINFRAME1); if (!m_wndCommandBar.Create( this ) || !m_wndCommandBar.Inser ...Show All

• SQL Server Merge Replication - Weird Conflicts for no reason

  Hi. I am using Merge Replication on Sql Server 2005 (which works much better than 2000 by the way) and everything is working great except occassionally I will get some conflict rows for no reason. The same column(s) of the same row was updated at both 'PublishingServerName.DatabaseName' and 'SubscribingServerName.DatabaseName'. The resolver chose the update from 'PublishingServerName.DatabaseName' as the winner. I checked our audit table and in every case there was no one updating the conflicting row(s) on the publisher that day. I have had to submit the losing row (which is the suscbriber) in every case. I am using COLUMN le ...Show All

• SQL Server Problem updating SQL2005 From MSAccess Form

  I have recently migrated from SQL2K to SQL2K5 and have a number of front ends in MSAccess Forms that worked fine with SQL2K but are not working with SQL2K5. I am able to connect and view the data in the SQL table using a file DSN but I am unable to update the records from the MSAccess form in SQL2K5.

• .NET Development XML DOM = load of c**p

  After years of hand-cranking XML I thought I'd give the DOM a try It's RUBBISH! Why can't you add a node & value with one simple line of code Why can you not set a xmlNode.value, but have to use InnerText Why is it the other way round for attributes Was this written by a bunch of monkeys with no input from MS It works nothing like anything else in .net It's unintuitive and illogical.  I've been coding VB4-vb.net for years and I should be able to pick this up no prob, but it's a load of C**P! Sorry, but it's Friday, and I expect better than this You can add a whole subtree by setting InnerXml pro ...Show All

• Visual C# How to get instance ID of object

  In VB6 I can use ObjPtr to get object pointer.  In .Net how to get it The advice is to use a custom override for the GetHashCode() function in ur own classes to ensure that it is unique: MSDN Content : This method can be overridden by a derived class. Value classes must override this method to provide a hash function that is appropriate for the class and that ensures a better distribution in the hash table. Classes that might be used as a key in a hash table must also override this method, because objects that are used as keys in a hash table are required to generate their own hash code through this method. I guess there is no ou ...Show All

• .NET Development Dispose and Application Lifetime Objects

  Hello, I have a Windows Forms application. When the app first runs (Form_Load) I create some disposable objects that will be used throughout the lifetime of the applicaiton (eg. a GDI Brush, SqlConnection etc). Do I really need to call Dispose() on all of these objects when the application closes, or will Dispose be called automatically for such objects when the app closes In other words, can I instantiate a disposable object when my app first runs, and not worry about disposing it when the app closes What about if my application terminates due to an exception Many thanks for your advice.

• SQL Server connect to local SQL2000 server from IDE

  Can I connect to a local SQL2000 server from the IDE. I saw the "SQL Server Instance Name" option and tried to change it to both (local) and SQL2K, but it then tries to connect to ./SQL2K etc and fails. I can only seem to (1) connect to a named instance (./namedinstancename), which I do not use. (2) be able to attach a new mdf, rather than connect to an existing db I know that the express edition is restricted to local dbs, but is it also restricted to named instances Thanks If the SQL2k instance is a default instance then you can connect just by using . or (local) or <<machinename>>.

• SQL Server Guids as primary keys

  Is it a good idea to use Guids as primary key. What is the impact on performance. Guids are random by nature that may have an impact on writing clustered index. Any comments or suggestions I'm not a complete expert, but one problem I know of with GUID's with clustering keys is that they are not naturally increasing so this could introduce lots of fragmentation in environments with lots of inserts. They are also wide (16 bytes) so having them in all indexes and foreign keys can be a hit to the size of the database, scan performance, etc. ...Show All
