• Game Technologies: DirectX, XNA, XACT, etc. Rants on XNA 1.0

  This is my first reaction when I installed and tried the 1.0 of XNA. To summarize my feeling: it's still 95% for XBox and no nearer to replace the old MDX 1.0. So I decided not to migrate from MDX to XNA though I want to do that very much. I feel like MDX 2 more; amen to MDX 2. The hardest issue for me is the content pipeline, which is very necessary, but the workflow is fixed and it assumes the contents are only built before the program runs. The helper functions wrapping D3DX can only be used with types in the content pipeline. I have to utilize the full content pipeline just for generating something dynamically, of course with significant performance cost. Or I have to write those D3DX utilities my self. Currently I don't have a good id ...Show All

• Software Development for Windows Vista What is LVN_FIRST - 88?

• SQL Server How can I create a DTS package to update a table with data from an Excel spreadsheet?

  Every month a client sends a spreadsheet with data which we use to update matching rows in a table in the database. I want to automate this using a DTS package but am having quite a bit of trouble accomplishing what I think should be trivial task. I've been attempting to use a Transform Data Task with a modification lookup but I just keep inserting the rows from the source excel spreadsheet in to the existing destination table without ever modifying the existing data. Any guidance would be greatly appreciated as to a best practice approach.

• Visual Studio Tools for Office VSTO deployment close to solution

  Hi all, I'm backing down to make sure I find a way to deliver to my customer the next few days: I have developed an Excel template with some .NET code behind using VSTO 2005. Not the SE, the first version. My solution uses another .NET assembly (helper.dll) besides the code assembly data.dll "behind" the document (data.xlt). I added a setup project to the solution. Which isn't enough of course. I created to separate install classes, one to install a policy code group thats gives Full trust to data.dll and one to bind the data.dll path to the data.xlt document (via ServerDocument). I added the custom Action to Install the CustomSetup.dll with these installer classes. Now to my questions: Are there any walkthroughs to t ...Show All

• Visual C++ Any interest in building an FAQ?

  I'd like to propose that we put together an FAQ to address some of the issues that pop up regularly here. It seems like we have an awful lot of questions like: - "How can I call my C#/VB/FORTRAN routines from C++ " - "How do I compile and run my project " - "I've included the correct header files, so why am I getting LNK2019 errors " - "How on earth am I supposed to use destructors/finalizers/IDisposable " And of course these are all valid questions! But since they are common questions which tend to be answered in the same way from one thread to the next, I think it would be very helpful to have all (or at least most) of the common answers in one single place. This would be helpful both to aske ...Show All

  I have an application that I need to send mulitiple emails from. There are about 10 users who will have permission. However my IT Group has locked down the smtp server and will not allow "Applications" use the smtp method. I remember in vb6 I used mapi to send emails using outlook that was on the users computer thus giving my IT folks traceability of who is sending what and not having to set up 10 people on the smtp permissions. Can this still be done using outlook(mapi) Try using SmtpClient.Credentials so you'll logon to the SMTP server with a username and password... ...Show All

• SQL Server How to dynamically assign database name in query or store procedure?

  Hello, I am not sure if this possible, but I have store procedures that access to multiple databases, therefore I currently have to hardcode my database name in the queries. The problem start when I move my store procedures into the production, and the database name in production is different. I have to go through all my store procedures and rename the DBname.

• Microsoft ISV Community Center Forums Creating MROUND function

  Hello, MROUND is a built-in function in Excel that round a number to a specific multiple. eg. =MROUND(21,5) rounds 21 to the nearest multiple of 5, which gives 20. For some reason this function is not available in my Excel (2003) and so i thought it may be useful to write the function myself using VBA. However i'm not very familiar with VBA so can someone please help me to kick start my first VBA function. Thanks! ps. i've found out after that to add the function all i have to do is go Tools --> Add-ins and tick Analysis ToolPak in the dialog box. Normally i would use the program's built-in help whenever i have queries. The thing is there are some missing pieces of my PC's VBA help file. I tried to look for solution ...Show All

What are the problems associated with accessing data remotely in a situation where a client application is directly accessing a SQL Server database over the internet There are obviously security issues related to preventing unwanted access to the database, but what about performance issues Are there connection reliability issues, network limitations, etc., related to the effectiveness of a direct remote connection to SQL Server An alternative architecture we are considering is a 3-tier model with a middle-tier application server (web service).
