• Visual Studio 2008 (Pre-release) ICollectionView grouping

  I have virtual IList<T> implementation (Db4oList) for db4o ( www.db4o.com ) object database and want to add ICollectionView implementation. I have described one problem with ObservableCollection here: http://forums.microsoft.com/MSDN/showpost.aspx postid=571091&siteid=1 But there is also related problem: Db4oList keeps only specified amount of objects in memory. E.g. say I have 1 000 000 objects (items) in it loaded from db4o database. I keep only 1 000 of them in memory when enumerating the list or using its indexer to access items. I have no problem with sorting or filtering, but the problem is with grouping, because when ICollection.Groups could have too many objects and because it is defined as ReadOnlyObser ...Show All

• Visual C# How to know the connection bandwidth from program?

  Is there any way to find out the bandwidth of my connection through program I assume you mean your Internet connection. Doubtful, the System.Net.NetworkInformation namespace doesn't contain anything like it. Connection speed is usually determined by your modem; your PC talks to the modem at normal Ethernet speeds so can't possibly know how fast the modem communicates. ...Show All

• Software Development for Windows Vista TEST CASE 30: Problems with verification on Russian Windows Vista

  Our product has Russian language only, and we test it on Russian localized version of Windows Vista. The behavior during TEST CASE 30. Verify the application is Restart Manager Aware (Req:3.1) is not correct. Let me explain. Our product is not a service and is not designed to restart after shutdown, so to test I used the command: rmtool.exe –p dwPID –S The product does close. When I tested on English Windows Vista, I did get only the Information message (in fact there were three Information messages: Starting session, Shutting down the application, Ending session). But when I tested the behavior on Russian Windows Vista (both 32- and 64-bit versions) I did get the additional 4th message of Warning type, saying that ...Show All

• Internet Explorer Development IE7 and changing an image in a different frame

  We have a series of GIS mapping applications that run using ESRI's ArcIMS software with a javascript based html viewer. We use a series of frames on a single page to display the base map, legend, table of contents, and an overview map.

• Visual Studio Team System How to get DB Pro ?

  I do have asked this question in the Visual Studio Newsgroups, but didn't get feedback. So I'm hoping to get some light from this group :). I do have Team Edition installed already, however without Database Professional. On MSDN there is a 3.88 GB ISO with Team Edition Database Professional and a Trial Editon of 19 MB. I actually only wanted the extra bytes in addition to my current Team Edition. Can I use the Trial Edition or do I really have to get the whole 3.88 GB Thank you everybody for the help. The link from Richard is exactly what I was looking for. And also getting to know that what is called "Trial" on MSDN works with a current installation was very helpful.

• SQL Server Deployment to one Database 'Clearing' Another...

  Hi, We have a setup whereby our production server builds to a build cube overnight, and if and when this completes successfully, and passes sanity checks, it automatically backs up and restores the cube over the top of a 'live cube'. This seemed like a fair enough plan - it allows developers to deploy to the production server without breaking the production-live cube, however, we have noticed that deploying to the build cube database sometimes results in the clearing out of the production cube database (much to the users' dismay!). Anyone else seen anything similar, or have any ideas as to what the problem could be Thanks, Will. First time I hear about something like that. Try and see if ...Show All

• Smart Device Development Multiple instances of an application - bad

  I have an application running under WindowsMobile5.0. I have used the code below to make sure that I only get one instance of the application (I'm talking to a SDIO module - don't want more than one instance). It works fine after the first instance is up and running. However, if I tap the application name in the 'File Explorer' multiple times (4 or 5), I end up with the application launching 2 or 3 or 4 times. I have not yet found a way to prevent this. The reason this causes a problem is that the spinning processing icon doesn't appear immediately after the first tap. It is not obvious that the tap was accepted and it is not uncommon for the user to tap a second time and this can cause the problem. static class Program { [DllIm ...Show All

• SQL Server Odd null behavior

  I am writing an upsert proc that should detect the change in state for a record. The change in state happens when a particular date field (default null) is populated. However, I can not get a record set that detects the changes properly. Here is an example set ANSI_NULLS on go create table #t1 ( ID int, DateField datetime ) create table #t2 ( ID int, DateField datetime ) insert into #t1 (ID, DateField) values (1, '7/20/2006') insert into #t2 (ID, DateFIeld) values (1, null) select * from #t1 join #t2 on #t1.ID = #t2.ID where #t1.DateField <> #t2.DateField drop table #t1 drop table #t2 The select should return a record because NULL does not equal '7/20/2006' but it doesn't.
