• SQL Server Is SQL Server Express designed for production use?

  Per the subject line : Is SQL Server Express designed for production use re: > are you experimenting inconveniences None. I was wondering, mainly, whether SQL Express differed from MSDE ...which wasn't designed for production use. To further the question : Express will only bind to one CPU at a time, and it cannot run queries in parallel. Express cannot use more than 1 GB of RAM at a time for queries and data pages. SQL Server 2005 will handle many more concurrent queries than the Express version. No one database in Express can be larger than 4 GB. Data mining, Data Transformation Services (DTS) and reporting functions are not available for SQL Express. Other functions not available in Express include clustering/mirroring, full- ...Show All

  But it seems to be all in c language doesnt visual basic express support the typical visual basic language And if so how do I configure it to do so, and find info on winsock and other things that is related for visual basic and not c language Well, 1. You're in the wrong forum 2. Visual Basic Express Edition uses Visual Basic 2005. Visual Basic 2005 and its predecessor Visual Basic .NET have very many differences vs. Visual Basic 6.0. These difference mainly revolve around VB.NET/2005's higher compliance to object-oriented programming principles.

• Visual Studio Microsoft Unit Testing Framework?

  Hello, If I am using the Standard or Professional editions of Visual Studio 2005, can I make use of the unit testing framework provided by the Team Suite For example, is this Unit Testing Framework available (and legal) to use outside of the Team Suite (i.e. Team Edition for Software Developers or Team Edition for Software Testers) If so, where can I obtain a copy (or SDK) that can be downloaded and used with my Professional installation I am not looking to get all of the features out the Team Suite into my Professional installation, just the ability to write some unit test classes and have them run in my build script. Would like to continue to use Microsoft tools, but I guess an alternative would be to use NUnit. TIA On ...Show All

• Visual Studio Days of Week and Color Names instead of data

  I'm new to CR with VS 2005. All I'm trying to do is to create a report from the fields of a table in an MS Access db. I used the wizard and selected all fields. Of the fields I have A_Number, which is a number up to 13 characters. When this is displayed in the report it shows days of the week instead of the actual A_Number data. I also have a field for Record which shows up with color names, like Fuscia for example, instead of the actual data. After reviewing the rest of the data in the table and what is displayed in the report none of the data displayed is correct. It is as if it is getting it from thin air. Any ideas You were correct about the random data not being present in the actual application. Unfo ...Show All

• SQL Server DR: Replication vs. log shipping vs. clustering vs. database mirroring........

  Up to now we have gotten by without having any local DR copies of servers (if a sql server goes down we are usually able to get it back in less than 3 hours). But I want more now. I want to trim the "down" window to no more than 5 or 10 minutes. (Immedate failover would be nice but is not an essential requirement. The essential requirement is to loose no data!) I have a spec of knowledge in these areas: SQL 2005 Clustering (requires approved hardware, quorum disk, etc. involved) SQL 2005 Replicaiton SQL 2005 Log Shipping. SQL 2005 Database mirroring. ( needs three servers) Which approach do you think is the most straightforward, sparing of hardware, yet reliable way to get us back up and running after a sq ...Show All
