• .NET Development DataSet.RejectChanges() vs Transaction.Rollback()?

  are these the same thing if not what is the advantage and disadvantage from your experience Thanks You've been doing some financial calculations on a piece of paper and you've decided not to do it and crossed it all out, that's DataSet.RejectChanges() equivalent – local changes in memory are canceled. You've done calculations above, wrote a check to somebody based on results. But something gone terribly wrong, so now you're calling your bank to stop payment; that's Transaction.Rollback() equivalent. Changes are canceled while been submitted to the server, it’s no longer a local thing.   ...Show All

• Visual Studio Team System Beta3 Error 32000 (tfsadminutil) on app tier

  When installing the Beta3 application tier I encountered an error 32000 near the end of the setup. Data tier went perfect. Both data tier and app tier are installed on a clean virtual Win2003SP1 machine. Followed all the steps in the manual, but had to cancel the setup of the app tier because the service account had disappeared from the local admin group. Added this user to that group again and started setup. Everything went fine until 95% of the service setup: Error 32000: The Commandline "'C:\Program Files\Microsoft Visual Studio 2005 Team Foundation Server\Tools\TfsAdminUtil.exe" Setup VSTS2\tfsservice  beta3-data TfsWorkItemTracking;TfsVersionControl;TfsActivityLogging;TfsBuild;TfsIntegration' returned non-zero value: -1.

• Software Development for Windows Vista Database Access within Activity

  Hi, If some of my activities (such as Code Activity or Custom Activity) need to connect to the SQL database to collect or update some data. What is the best practice to store the Connection String I don't want to hardcode the connection string as it may change. Andy Ho Hi During some Activties like Design Time Activity the application cann't read information from Configration file, so we store information that is required in designe time in Registry and full these information when required. You can also create a file to put information but it is not a standered way of doing the job I think so., Because Microsoft Also use registery for information like this one, The store to retrive the registe ...Show All

• Visual Studio 2008 (Pre-release) How to drag/drop custom control in grid.

  I was wondering if anyone has a good example of how I could drag and drop a custom control into other columns and rows within a grid. Yes. His is the code that I am currently using. The problem is that I need to lay out objects in a linear fashion. If I could have this work in a grid it would be great. Also I need to be able to drag from one grid to the next grid. Or in Josh's code, be able to drag from one canvas to another. Any ideas ...Show All

• .NET Development remoting new guy - have some questions

  I am interested in learning about remoting and I have some simple questions. I am new to remoting and would appreciate some help. I would like to have our customers remote to our server for all data access functions so that we can store data in our secure data center for our clients. (ASP type model essentially where we host the data for the customer and allow them to access it from anywhere) Our Data Access layer has about 200 classes today each implementing custom methods like so: Example: public class OrderDAL { public dataset getOrderInfo() } public class CustomerDAL { getCustomerInfo() } I want our users to be able to remote to our server and call any method in any of these Data Access Layer ...Show All

• Visual Studio Mutliple DSL Installation

  I know there is no support for mutliple DSL intergration yet. But, it will be great, for those ones that are developing the integration "by hand", to have, at least, an only installation project. There is a way to achieve this with the current version Thanks in advance... Yes, something like that. I thought in one only Package, but, this approach could solve my problem too. How can I integrate several wxs files in one only msi project I am new in this stuff. Thanks in advance.. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Drastic FPS fall,when rendering QUAD

  Hello guys, I've been working on my 3D directx game for a while and I've recently added QUAD(ship cockpit), inversly transformed to VIEW, so its like GUI. However, I am encountering big fall FPS - well normally my time delay between frames is 17 ms, but when I render quad it jumps to 50 'ms'. What's strange is that rendering tha quad + needed preRender+postRender takes just 6 'us'. So why is there 5000x longer delay. Moreover, I've noticed that I can bypass time delay increase by rendering quad without being scaled and transformed to [0,0,1]=> (further to the front) position - there is no TIME INCREASE...but then the "cockpit image" takes just 30% of the screen and so it is not very realistic. Some info about the imag ...Show All
