• Visual C++ linking of dependant projects

  I have a solution with 2 projects... Project a is a console app with MFC support and project B is a dll with MFC support. I have set project A to depend on project B. When I build the solution it fails as there are unresolved externals (from Project B) I have turned in the verbose option on the linker and can see that the lib isn't scanned. Is there somthing else I need to do to get my project to build Robin Have you declared your Cb class like this : class AFX_EXT_CLASS Cb { ... }; The AFX_EXT_CLASS makes sure that all methods of your class are exported by your dll, if you don't use MFC you can use __declspec(dllexport) instead (which AFX_EXT_CLASS reverts to as well). ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. My new game running on Beta 2 (Dr. Popper)

  Just wanted to let everyone know now that I have migrated my game to XNA Beta 2, and have put it up for download at http://www.bluerosegames.com . It's called Dr. Popper and it's a puzzle game similar to Pop'em, Jawbreaker, and Bubblet. I will post full source code for the game in a few days, but for now if you have any questions feel free to ask. Thanks, Bill Jim Perry wrote: I'll have to wait until lunch to try it out since I'm at work, but it looks good. Thanks Jim, hope you like it. I'd like to hear what you think. Bill ...Show All

• Visual Studio 2008 (Pre-release) Yet Another Binding Question

  After breezing through several basic experiments while trying to learn WPF/XAML, I've tried to tackle something that is beyond me. After much searching and reading, I'm afraid I'm more confused than when I started. Hopefully someone can point me in the right direction. The desired end result is a StackPanel that displays one or more UserControls (Gadget) contained in an ObservableCollection. I would like to be able to filter which items are display in the StackPanel, so I think a CollectionViewSource needs to come into play as well. So, as a very basic example, the Gadget control XAML file might look something like this: <Border xmlns=" http://schemas.microsoft.com/winfx/2006/xaml/presentation " xmlns:x=" http: ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. End users shouldn't have to rewrite XNA math functions in order to improve performance.

  The overhead of passing a 64 byte Matrix by value is significant. Most especially when you are comparing two matrices for equivalency (==), or performing a Vector*Matrix multiplication (Vector3.Transform(Matrix)). The following matrix comparison function performs 5-10 times better than your built in == comparison. If the matrices are equal, then it is about 5 times faster. If they are unequal then it fails fast, and is about 10 times faster. public static bool Equals(ref Matrix a, ref Matrix b) { // i check the diagonal first for quick fails return a.M11 == b.M11 && a.M22 == b.M22 && a.M33 == b.M33 && a.M44 == b.M44 && a.M12 == b.M12 && a.M13 == b.M13 && a.M1 ...Show All

• Visual Studio Team System Trouble with VSTS / Sharepoint remoting services

  We are evalualting VSTS & Sharepoint. As a small company, our Team Foundation Server is accessible via the public internet using dynamic dns (dyndns). What happens is that all of the reports fail when coming in over the public internet, because the redirect url is pointing to the actual server name, not the url on the internet. http://<servername>/sites/project/tfsredirect.aspx%flsreport works fine internally, but on the public internet the address should be http://<dynamic dns name>/sites/project/tfsredirect.aspx%flsreport This is a real showstopper for us, as we want to be able to allow our clients to view reports from sharepoint. I'm sure we're not the first to encounter this problem, any advice would be a ...Show All

• Windows Forms SelectedIndexChanged Event of DataGridViewComboBoxCell firing multiple times?

  I am currently having an issue when using the EditingControlShowing event of a DGV in combination with the SelectedIndexChanged event of the DataGridViewComboBoxCell. I have 4 unbound combobox columns within a mixed DGV (there are 4 databound checkbox columns as well). I am using strongly typed collection objects for the unbound columns. The third column is dependent (the cell is created and databound) on the selection that is made in the second column. This same dependency also exists between the second and the first column. The issue I'm having relates to the number of times and the value of the EditedFormattedValue of the current cell as the comboboxes are used. In the first column when I use the combobox, the event only fires after I h ...Show All

• SQL Server Can I use keyword Like with a Parameter

  Should be simple. I'm writing a report to find employees by last name. I want the user to key in at least a few characters of the last name and the report will search for all last names that are like that. I know in TSQL it would go: Last_name like 'Jones%' But how do I set up a parameter in Reporting Services I've tried: last_name like =@name% Any ideas Thanks, Jim You would probably need to use dynamic sql and expression. ="Select * from table1 where last_name like '" + @name + "%'" Or use a stored procedure and perform the like statement within it. cheers, Andrew ...Show All

• .NET Development Creating a database storage and information access?

  Okay I'm totally lost. I've been trying to make a website for our customers to sign into where they can view specific details relating to their company (their product purchases, warranty end dates, and points balance tracking). How do I go about creating such a database storage and access website. Does anyone know where I find a tutorial or if someone can help me out. I've tried everything I could find and nothing. All I got so far is the actual layout and log in working. Now i need the backbone of the website; the database functions. Thank you. The best way as I explained above is to add a query in you table adapters. For example in the purchase table adapter you could add this query: sele ...Show All

• SQL Server Executing Package From Web Service

  Hi, I'm having another go at attempting to call an SSIS package from a web service. The Web Service is set up on the same server as the sql server and SSIS package deployment. When i attempt to run the pacage from the web service it starts and then inmediately fails. I can see this in both the Integration Service Logs and the event viewer. If i click on the package itself and run it using the DTExecUI, it runs without a problem. No logs are output by the package when called by the web service. Can anyone suggest anything that i could to see if i can diagnose where the problem stems from.
