• Visual FoxPro Coming from Excel to VFP9 and need help understanding math functions on cells

  I have set up a simple data tracking form that breaks out the associated costs of a vehicle going to Auction ( dealer costs, transportation fees and so on) for my employer. It works great, and I can enter data into the database successfully, and my Report will print it out nicely sorted by Store. I would now like to create cells on my data entry form that calculate and display various math procedures on the data being entered. For instance, a cell that displays the Sum of all the fees and costs, and then a Result field that displays the amount we sold the car for minus the Sum total of the fees. Boy, do I need some help getting my ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Vector3.Project() doesn't work.

  I guess I posted this in the wrong forum the first time... I'm trying to project the location of a mesh in world space back to screen coords. I've been searching around with no real luck. I've seen people say that you should use Matrix.Identity instead of your world matrix, but that makes no difference for me at the moment. It's not that the code causes an error, it doesn't. It's just that after projecting pos, it remains almost identical to what it was, off by about 0.5. Considering my values are typically in the hundreds, this is a minor rounding error. I get the exact same results using Unproject(). I would have expected that proje ...Show All

• Visual Studio IWizard

  Is there a template that generates a Wizard and has the boiler-plate code for IWizard Where is IWizard documented Thnx in advance. replacementsDictionary.Add( "$consolemessage$" , consoleMessage);   Here, the consoleMessage variable contains the value we receive through the Form from the user. This basically tells the template engine that wherever you see $consolemessage$ in any of the files in the template replace it with the string in consoleMessage varibale before creating a project. Thus you can define any number of custom parameters and replace them with values provided by user input. Th ...Show All

• Visual Studio Team System Rename VSTS Project

  I saw another thread where you could not rename a version control folder at the root level, but, have not seen anything about renaming a VSTS project that would also rename the top level directory...any cool command line utilities to do this...I don't want to rebuild my VSTS project... Just to make sure it's clear: you cannot rename Team Projects in V1 period (it doesn't matter if it's the command-line, Team Explorer, SCE, web services directly whatever). However, it's something we're considering for V2. I just wanted to make sure the "from Team Explorer" part wasn't confusing the issue for anyone ...Show All

• Visual Studio Team System VSTS Architect vs. VSTS Developer

  With he proposed changes in MSDN subscriptions and Visual Studio licensing, I now have to make a decision between VSTS Architect and VSTS Developer. As I understand, MSDN Universal subscribers will have a choice - they can either go for VSTS Architect and VSTS Developer. I believe that I need both architecture and development tools. Which out of two should I go for The information was interesting but too high-level to be really useful or answer the questions I feel most developers have. I hope you folks will be releasing something with a bit of meat on it like a feature by feature breakdown of what is included in each edition in t ...Show All

• .NET Development How to insulate the client from poor network reliability?

  We are developing some in-house ERP applications, that will use an WinForms UI and an IIS-hosted Web Service.  The clients will be using a wireless network that is prone to alot of interference.  I wish to ensure that the request and response are not corrupted due to network interference.  What would be the best way to accomplish this I imagine some form of checksum on the SOAP messages would suffice.  Is something like this built into web services via VS 2005   If not and I have to implement it myself, what would be the best way to go about accomplishing this FYI, I am accessing the web services via a proxy c ...Show All

• Visual Studio Team System Using Team Explorer outside VS 2005 Team Suite.

  Hi, is it possible to use the 'light weight' Team Explorer client app outside of VS 2005 - I'm using Beta 2. The scenario is; I'm developing in both VB6 and VS 2005. I want to migrate the old VB6 source code in to Team Server. I know I will loose what VSS integration I had in VB6, so I need someway of checking out files when I'm not in VS 2005. Does that make sense I have tried installing the Client part of Team Foundation on my dev machine which has VS 2005 already installed. Once the setup had finished I still couldn't find any shortcut to the Team Explorer (except in the VS IDE). TIA Graham Ah, okay, I se ...Show All
