• Architecture Passing Business Objects through tiers?

  I typically build my application using a three tier design with a domain model. Domain Model Presentation (windows or web forms) Business Logic Data Access Logic I see many examples out there that don't use a domain or logical model and just business tier. In some of those examples i have seen the sql generated in the business tier and then passed to a data access tier for execution. I don't like this approach as i don't like seeing sql in the business tier. What is the best way to pass the business entities to the data access tier without a circular reference I typically create a class library project for the business logic and another for the Data Access logic along with my windows/web application. To solve this pro ...Show All

• Visual C++ Arrays of structs don't display in debugger

  When I have an array of structs, the Autos window, tooltip, and Quickwatch all display only the first element of the array. For example, struct Variable { char name[25]; enum VarTypes type; ... }; Variable var[10]; Now when var is displayed, there is a single-line format which shows the structure members for var[0] only. If in Quickwatch, you type "var,10", everything displays correctly; i e, you get a subtree with subscripts [0]. [1], etc, and each of these can be expanded to show the members of the struct. I already posted this in the "resize autos" thread, which you were reading. Here it is again: Here is what I get, every time: ...Show All

• .NET Development NET 1.1 AND 2.0 UNINSTALL/FIX/INSTALL/UPDATE INOP

  I can not do a thing with these programs. Totally hosed! My other 3 computers seem to be fine, but there is a problem when you can not remove a program in safe mode. This has to be a very common problem and where is the fix Update fails also for .net. I have a clean download from work on my mem stick. 1.1 and 2.0 with updates are installed. The problem surfaced when I used auto update for a security fix and it would not install. So I tried to remove them with no luck. I have removed 1.1 from my other computers with no problem at all. very strange. ...Show All

• Visual Studio Team System Weird Compare Issue

  When I click the "Check-In" button on a TFS SCC project in the source control explorer I get a list if .vspscc and .vssscc file conflicts that occur. When I click on resolve and then click the compare button I get a pop-up window that has the notification icon, 2 buttons but no text at all. Not even on the buttons. What is going on here I installed TFS about 4 days ago. Cheers, Mark Regardless, the fact that it repros in both providers is interesting -- there's only so much shared code between them. Some things that might be helpful: - a screenshot showing the state of the resolve dialog(s) when the pop-up appears - a stack trace from a debugger at the time of the bug - configuring a 3rd-party di ...Show All

• Visual C++ Intellisense becoming unable to resolve objects

  I'm posting this here and not in the general Visual Studio forum because my experience so far tells me the situation with C++ is different than with, say, C# (I have so far at least one example where VS's tools behave worse in the C++ environment than in that of C#). I have Intellisense getting confused and unable to resolve objects so often that I find myself closing the solution, deleting the *.ncb file, and reopening the solution. It almost makes me wish I had a "rebuild Intellisense" button... Kamen If I find the time - I will. It's not like MS will jump and solve it immediately. In mean time - the issue that I reported has not been answered , period. I also think it's a travesty that users can mark their own po ...Show All

• Smart Device Development Questions on using RIL on Smartphones

  Hello, I am new to developing on the Windows Mobile platform and have just started writing an app for Smartphones running Windows Mobile 5.0. My first task is to get the cell tower ID that the phone is currently registered to. I searched MSDN and other discussion forums and found that I can use the RIL functions to get this information. My first confusion was wether RIL was even supported on Windows Mobile 5.0 since MSDN includes RIL and Cellcore under 'Windows CE Embedded 6.0'. However, judging by some messages on other forums, RIL does seem to be available on Mobile 5.0. So far, so good. I tried to write a simple app using RIL functions but couldn't build it. I can't find any RIL-related files in my SDK install. After some more searchi ...Show All

• Software Development for Windows Vista Windows Installer - "Change" action does not require admin password in "Programs and Features"

  Why does Windows Vista not prompt for admin password when selecting "Change" in "Programs and Features" Even a limited user is able to add or remove features from our installed product. The strange thing is that the installer prompts for elevation when installing and uninstalling. This appears to be a bug in Vista only (and a pretty serious one at that). On XP, only an administrator can change the set of installed features. Our installer has ALLUSERS set to 1 and ARPNOMODIFY set to 0. Mike Morrison Yes, the MSI is signed. Elevation is also not required if you run the installer and choose "modify" from the MaintenanceType dialog. I'm not exactly sure what you mean with your que ...Show All

• Windows Forms Single click acting as double click in form designer

  For some reason, when I'm editing a property of a control in Design View and then single-click back on the form designer, the IDE acts as if I double-clicked, and goes to the code for the Form.Load event-handler, for example. Has anyone else experienced this Is there a setting that I changed somewhere that fixes this, or is it a bug Thanks for your help. -Mike I've been having the exact same problem too. I'm not certain, but I believe it began happening when I upgraded to SP1. It doesn't happen all the time. I haven't been able to come up with a correlation between number of files open, number of projects in the solution, number of forms open, or anything like that. I can't reproduce it right now.

• Game Technologies: DirectX, XNA, XACT, etc. Scene statistics

  It is possible to get scene statistics: total number of triangles, number of visible triangles How to do it On Windows, you can use the PIX tool (part of the DirectX SDK) to obtain all kinds of information about your scene. The overlay statistics mode is particularly useful here. We don't have any automatic way of doing this on Xbox, so you'd have to add your own instrumentation to your drawing code. ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. XNA Build for game artists using Microsoft Team

  Hi there, Lets say I want to use XNA Build for my next project (which I do)... I use Microsoft Project to track my art tasks, that's integrated with Microsoft Team tools so that my artists can use Microsoft Internet Explorer to access my Microsoft Sharepoint web pages that access Microsoft SQL Server where my Project tasks live and the art assets are version controlled into Team. Not a problem for my developers who use Microsoft Visual Studio Team Edition for Software Developers. I can load a standalone version of Microsoft Team Explorer on my artist's workstations so they can see/track their tasks, but I want to use XNA Build so that we can keep all their art assets in projects and solutions. Then we can use Team Build to have conti ...Show All
