• Game Technologies: DirectX, XNA, XACT, etc. Multiple XNA Questions

  Hi, I looked at the FAQ for XNA and I couldn't find the answers to a few of the questions I have regarding it. So if someone could help answer my questions that would be awesome. ^_^ 1. Is it possible to sell games for money (either on Windows or 360) after they are 100% completed 2. How can I find out what shader model my graphic card supports (I want to find out if my computer will be able to handle the sample and starter kits that recommend Shader Model 2.0) 3. Is it possible to make online multiplayer games (Not to the extent of a MMORPG since I doubt it could do that (correct me if I'm wrong on that though), but what about something to the extent of a game like America's Army or something similar ) 4. If the last question ...Show All

• Visual C++ Cannot read data from Access 2007 database

  Hi. I’m trying to read data from an Access 2007 database. I’m working with VS 2005 C++ on Windows XP SP2.

• Visual C++ LNK2001: using unmanangedC++ in manC++

  Hi, i'm writing a new user-interface for a small software-company. The old interface should be replaced by the new one, the "inner core" should stay. The old program was written in unmanaged C++, but now I'm writing the user-interface in C#, so I have to use class wrappers. While building the managed C++-project (in a solution with the unman. C++-projects) there a some errors. For example: Error error LNK2001: unresolved external symbol ___argv nafxcwd.lib and Error error LNK2001: unresolved external symbol ___argc nafxcwd.lib Another one: Error error LNK2001: unresolved external symbol __pgmptr db.lib [db is one of the old unmanaged C++-projects] The settings are the following: Linker->Input->Add.

• Visual C++ Using animated GIF image in Forms

  Hi, I'm trying to use an animated gif image in a form within C++/CLI but so far without success. I looked at picturebox control but the image stay still, no animation. I browsed the NET to find any clue to my problem and got a few articles stating the fact that I have to make somekind of class that would rather display one at a time each frame found in my GIF. Any clue or easier way, any example on how to do it Thanks in advance, Stephane Please see these articles Add GIF-animation to your MFC and ATL projects with the help of CPictureEx and CPictureExWnd Adding GIF-animation using GDI+ ...Show All

• SQL Server Dynamic Security Stored Procedure Repeatedly Called

  I have implemented an SSAS stored procedure for dynamic security and I call this stored procedure to obtain the allowed set filter. To my supprise, the stored procedure is being called repeatedly many times (more than 10) upon establishing the user session. Why is this happening Thank you for helping out. As I mentioned, the dimension has some 2 mil members. I has a Security Filter attribute with some 50,000 members on which the allowed set is applied. The allowed set expression is StrToSet(<call to stored procedure here>). The stored procedure returns a comma-seperated list of the allowed members in the format [DimensionName].[Security Filter].&[key]. The stored procedure queries a d ...Show All

• Windows Forms I can't figure this "Enter" thing out! Please help.

  Ok, so I am creating a web browser. Everything is fine and dandy, except I wanted the capability of the user pressing "Enter" after they type in the URL instead of having to go click on "GO" button. Thats nice... So I go to the properties of the combobox, select "Keydown" and create a new keydown event. In that event, I write: webBrowser1.navigate(combobox1.Text); I run the program... and It works alright! However, it automaticly tries to connect the the URL before I even get it typed... So by the time I type in www.yahoo.com , it's already navigated there without me pressing the enter key. This is a neat little thing, but I don't want it to work that way. Is there some kind of Break I can use to stop the URL in the U ...Show All

• SQL Server Connecting to SQL Server 2005 remotely via windows authentication

  Hi I have installed SQL Server 2005 onto a server and then on my client machine I have installed SQL Server 2005 and the Server Management Studio. When installing it on the server I chose all the defaults so have not setup an sql username or password to connect as I thought I could use Windows. I go to the Server Management and registered servers, create a new one and enter the ip address of the server and choose Windows Authentication. The following error keeps appearing though and I am not sure what settings/where to check: Login failed for user ''. The user is not associated with a trusted SQL Server connection.

• Visual Studio Team System Bug in 'Move' feature?

  Hi, Here is a reproduction of the steps I took. I had a folder in TFS at the path $/Root/Recon. I mapped a local path to it in my workspace (C:\Dev\Recon). I then attempted to move the folder in TFS to another location and received a message to the effect that a move could not be performed because the fodler was mapped to a local path. That was ok, so I removed the mapping. Then I tried again and got this error: No appropriate mapping exists for c:\Dev\Recon. I tried this multiple times with the same end result. I even shut down VS and restarted it. Finally, I another random TFS folder to c:\dev\recon. THEN only it worked. Sounds like a bug. Or was I performing the move incorrectly If both the source and target are mapped when you t ...Show All
