  Hi. I've got a classic Master-Detail DB structure Master ID Name Detail ID Name MasterID I generate the EDM with EDM Designer and I add a navigation property "Details" from Master to Detail entity type, so I can have details related to a master entity simply by typing Master m = .... m.Details I've noted that if I type the code above and run it, the details collection is empty. I've to add m.Details.Load(); and then I've got the expected behavior. Is it a normal behavior Is it the ADO.NET lazy-load implementation If yes, doesn't the lazy-load mechanism have to be transparent to the user I hope that my questions were clear. Thanks. Roberto.

• Visual Studio Team System Team Foundation server sending the same alert content multiple times

  Hello, We have users that have subscribed to the standand "Work items changed by others" alert For some reasons, the TFS server sends the exact same e-mail over and over again. The user will receive it each hour all throught the day (exactly one hour, clockwork). The content are exactely the same. If we make further changes to the work item, the initial notification continues to be sent. I have seen the same behaviour on the check-in alert (the one that shows the change set information) I have only seen this behaviour on this one internal team project we have (we have installed may TFS at other customer sites and I have never seen this behaviour, nor can I see any other complaints about this).

• Visual Studio Team System Active Directory Domain Rename

  Hi. We plan to rename our domain like described in this article: http://www.microsoft.com/technet/downloads/winsrvr/domainrename.mspx Our Team Foundation Server is a member of active directory, and we heave many domain users connected to this TFS system. The question is: After domain rename must we make something/or perform some additional steps to keep TFS System still works like before And domain users can logon with previous privileges to our TFS system without any additional administrative actions best regards Slawek Sp. This is exactly what "tfsadminutil sid" is for. You'll use it with "/change olddomainname newdomainname" and it will update the SID's (security ...Show All

• Windows Forms Inserting items checked in checklistbox to database

  Hi, I have a checklistbox called from a table with permissions as value and a "Save" button. I am able to display the permissionlevel as checklistbox. For example, Read Write Execute Full Control (Save) button I have another table which associates with userid and permissionlevel. If a user has read and write permission in the table, when that user signs in, I want Read and Write checkbox to be displayed as checked. The user may uncheck or check more permission.

• Visual Studio Documentation Compiler - Sandcastle

  We did code complete of documentation compiler ( code named "Sandcastle") on June 15th and currently we are testing the tool building our .NetFramework documentation. We would like to release the CTP version of Sandcastle in Microsoft download center by next week. The perf in our testing has been great as we are able to build the entire framework content in less than 1 hour. I am in the process of going through final check and code signing required to post this in our download center. Please expect the CTP in the next week or so and I will provide an update here as soon I post the CTP. Anand.. Great, Thanks.

• Software Development for Windows Vista get PTS from MPEG2 live stream / demultiplexer

  I've got an MPEG2 transport stream which is pushed through the Microsoft MPEG-2 Demultiplexer, with audio and video streams being rendered through two output pins on the demux. Fairly standard stuff. I've also got another output pin carrying some private data in PES packets. These packets contain data that needs processing loosely synchronized with the playback PTS. Is there any interface I can use to query the live streams start position I'm after an absolute value (reference time) rather than the stream time. Any ideas ...Show All

• Windows Forms .NET 2.0 WebBrowser does not handle javascript calls, navigates instead

  Imagine a web page that includes the following <A> tag: <a id="ButtonOne" href=OnCheckout();"><img ... ></a> Any browser, including the application I'm working with that has a .NET 1.1 C# WebBrowser control embedded in it, will call the javascript OnCheckout() function when that link is clicked. I can expect that, because of the code in that function, I will shortly have a BeforeNavigate2 event fire where the URL is something like http://host.domain.com/page.aspx . Because that happens. Every time. So reliably that we sell it to customers. Now that the 2.0 Framework and VS2005 have come out (and for a few other reasons), we're writing a new version of this product that happens to use the .NET ...Show All

• Windows Forms datagridview cell editing

  I am programatically trying to edit some cells. I change the value using DG[index1,index2]=value. Then I execute EndEdit on the DG. But I notice that the currentcell is not the cell I edited. It seems to be causing problems. What is the best way to make sure changes are committed to the DataGridView once I make changes programatically. Thanks Nik When you edit a cell using DataGridView(cellIndex, rowIndex) = value and then execute DataGridView.EndEdit(), it does not actually change CurrentCell property of a DataGridView. To change it programmatically use DataGridView.CurrentCell = DataGridView(cellIndex, rowIndex) . ...Show All
