• .NET Development How to convert string to expression

  I am having an string "3<2", I would like to use it in a if statement as if(3<2). How to convert this string into an boolean expression. Can we convert a string like "a<b" into a boolean expression. You could use CodeDom - which is used to dynamically build up code (using code) to execute... have a look at the System.CodeDom namespace, in particular the CodeExpressionStatement class. If you have a look through the documentation (and on the internet for examples) you should be able to put something together. Hope that helps. Simon ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Spacewar Performance Problems

  Finally got my hands on a 360 controller today, so I thought I would give Spacewar a spin, unfortunately, it was a very, very slow spin. 2.5fps slow, even in retro mode. My laptop isn't the greatest (Pentium M 1.7Ghz, 512 RAM, X300 128mb w/ latest Omega drivers), but it should certainly be doing better than that. I've compared stats in PIX with some of the MDX samples, and nothing seems out of the ordinary. I tried the CLR Profiler on it, but from my limited experience with it, I wasn't able to interpret the results well enough to come to any conclusion. Any ideas Hey nuvem, We think we've found a bug in the Spacewar sample that may impact performace issues on some machines, we're still looking into ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. 3D picking - possible solution?

  I was pondering, and something occured to me. Let's say I have a 3D model. Now lets say I want to enable 3D picking for that 3D model. That is to say, I want the mouse to be able to change its properties / response when it is over the 3D object, or clicking while over the 3D object. I assume that one way to solve this would be to create a ray that originates from an equivalent point in front of the camera, and passes along a Vector3 through the scene. I could then test the ray to see if it colides with any 3D objects (or their bounding boxes) and return values for that particular object. But it also occured to me that this method for picking would be a huge pain in the neck, and would probably end up being far more costly in terms of pr ...Show All

• Visual Studio Tools for Office Using interop to connect to an already running instance of Excel

  I have a small test application which successfully opens up an instance of excel, opens a file called "myExcelSample.xls", activates the primary worksheet, and pulls data from specific cells in the excel file. Here's my question: If a user has already opened Excel, opened a file named "myOtherExcelSample.xls" and made it the activated workbook, how can I at runtime connect to this (already opened) instance of Excel and pull data from ranges on that worksheet I have found code snippets which let me poll for the instance of Excel and get back a ProcessID from Process.GetProcessByName("Excel"). Am I heading down the wrong path If I get ProcessID, is there a proper way to create an Excel.Application o ...Show All

• Visual Studio Team System Access tests stored in shared folder

  Hi, Is there any way to access the webtests stored in a shared folder and run the test locally I tried by mapping the shared folder to my machine, but not able to open the project.

Why can't you open the project, are you getting an error message If so, what does it say Thanks, David Gorena Elizondo [MSFT] VSTS ...Show All

• SQL Server How do I get a RS report onto an Internet app?

  I've written our first Reporting Services report, using SQL Server 2005. Since we've never used RS before, we may, or may not, have done some things correctly. One of the things is that we only have the Reporting Services, and Report Manager, on our SQL Server 2005 server, which is in our network behind our firewall. We also have an ASP.NET 1.1 application which is used by external users (other businesses that do business with us). Because of the nature of our business, we don't want people from one agency to access data from another agency. Since calling the report in RS involved passing parameters to the report in the URL, I decided that I would hide those details by putting the web page returned by RS into an IFRAME in an aspx page. ...Show All

• Architecture CRM products

  Hi This with regards to comparing CRM products with another standard non-microsoft products. If we were to compare Microsoft CRM Dynamics 3.0 with any other non-microsoft CRM products then what would be technical evaluation Mkft supports Sales, marketing, etc in their CRM but less with reports and integrity with exisiting system, or workflows. thanks Paresh. Oddly enough, my company builds CRM software that competes with MS CRM in the US, but we also sell MS CRM outside the US (it's a long story). I would look at the functionality you need ahead of any specific technology approaches. Buy the product that has the macro-functionality you need -- account management, forcasting, market ...Show All

• Visual Studio Express Editions Visual Studio Express Edition and MySQL

  Is there any way to connect Visual Studio Expres Edition to MySQL and collect data with C#   Thank's That's not true Figo Mei I just ported an Application I was building from MySql to Sql Server Express and both of them were / are working TCP Based, you just need to change your connection string to indicate the use of TCP instead of Name Pipes . And I'm programming in Visual C# Express Edition. For MySql using ODBC is the easiest way out, while not the best performing one. OleDB should be able too. I'm using OleDB now, but on SQL Express. It's all a matter of finding a valid provider. In the MySql homepage there are all the providers you need to install to make it work. Hope I have been useful. ...Show All

• SQL Server Combining multiple subreports into a single report

  The goal is to produce a single PDF consisting of a number of subreports. Some are landscape, others are portrait. The subreports may also be run as independent reports. The master report that contains them defaults to the width of the widest subreport, which is landscape. This causes all portrait subreports to spill over producing blank pages. Are there any work-arounds to concatenate multiple, single report PDFs into a single PDF and have page numbering too Thanks! I did check the landscape width for the reports both individualy and in the master report. They all render fine independently. I also tested the report rendering as I added each subreport to the master report. The moment I added the Landsc ...Show All
