• Audio and Video Development filecache

  Can anyone tell me something about the filecache I haven't found any detailed example code regarding the filecache. So in what cases do I have to preload files Especially how is this preloading done Do I have to enter something in the manifest or playlist Most of the APIs and Markup elements that allow you to reference resources (such as images, sound files, other Markup files, etc.) require that those resources be present in the "File Cache" before they are used. The File Cache is divided into two areas: API Managed Area (AMA): This corresponds to URIs of the form file:///filecache/resourceFile.png . Files can be copied to this location at runtime using FileIO.copy(). After this, you c ...Show All

• SQL Server Is SQL Server Express what I need????

  Hello, Someone I know told me that they thought SQL Server Express was what I am looking for. Before I get in over my head I need to know from people who use it if this is really for me. I have build my own web site using very basic HTML and CSS. Nothing fancy I am very new to this. What I want to do is have a customer able to enter their email address, once they have hit submit, I want the email address to go to a database (which I believe this software is going to help me set up ) and a document sent to them. I was thinking of a PDF attachment to an email since I have not figured out yet how to send an email that looks like a web page. I now have a customer inquiry form on my site that is sent to a perl script in my cgi bin ...Show All

• Visual Basic Can you digitaly sign your program?

  hey i was wondering can you digitaly sign your program and also make to be able to install into C:\Program Files is this possible thank you. You can digitally sign your application with a public/private key pair even in Visual Basic 2005 Express without purchasing a certificate. It may be neccessary to download the 2005 SDK (I hope not). There is a tool called sn (strong naming utility) that lets you generate a key file, you can use this tool to sign your assemblies and in your project properties under the "Signing" tab there is an option there (not the sign the click once manifest) to sign the assembly. That should provide some measure of security against tampering/spoofing, for you. ...Show All

• Visual Studio Upgrading VS6.0 Add-in to VS2005

  Hi, I have a Add-in (written in VC++) that works fine with VS6.0 We are now upgrading to VS2005 IDE and this Add-in does not work. It does not even build well. There used to be a directory "Objmodel" in the VS6.0 installation. The Add-in uses this directory. This directory is no longer present in VS2005 installation. How should one upgrade 6.0 Addin to work in 2005 I thought merely opening 6.0 project in 2005 would do the needful, apparently it is not all that easy. I can share my code if someone is willing to help, it is just 15 classes. Thanks in advance, -Shrikant Hi, I am not sure about C++ add-ins, but in general the extensibility model of VS.NET 2002 (7.0)/2003 (7.1)/2005 (8.0) is different ...Show All

• Visual Studio Running VS 2005 under a non Admin Account

  I am trying to stop logging into my machine as a adminstrator. To do this I tried to launch VS 2005 with this command: C:\WINDOWS\system32\runas.exe /env /user:<Administrator Account> "C:\Program Files\Microsoft Visual Studio 8\Common7\IDE\devenv.exe" Where <Administrator Account> is replaced with an appropriate account All seemed fine until I tried to design a stongly typed dataset. Then I got the message the message: Key not valid for use in specified state I got around this by removing the /env. (I think the encryption key is based on the user's sid but with the /env switch I was referencing the key for my logged in account as opposed to the runas account) I also had a problem when I deleted files.

• Audio and Video Development Timing Animations within Script

  One of the problems I am encountering as I put more animations script side, is the ability to have animations occur one after the other, rather than simultaneously. Is there a straightforward way of having animations occur one after the other For example I want the following script to fire in sequence, one assignment after the other, but only after the previous one is completed. document.FOO.style.animateProperty("x","500px",2); // don't turn off display until animation completes document.FOO_BUTTON.style.display = "none"; Is wait(time) supported (iHDSim does not like it)   If so is in sync with the application tick or what The last argument to createTimer() is basically a function pointer. You cannot pass a function with arg ...Show All

• Visual Studio 2008 (Pre-release) Image formats for toolbars?

  I'm curious what people are using for images on WPF toolbars Are you using icons, bitmaps, a geometry in XAML, or It's nice that you can easily make an interface scalable with WPF, but that implies that some sort of vector images would be best. But how do you make those look good when sized down to small areas like 16x16 I'd like to hear from some developers/designers that have been working with this awhile on what's worked best for them What gives you the best tradeoffs between ease of creation, good looks at larger sizes, and good looks at smaller sizes Not sure if others are doing the same, but I'm finding myself using png for icons, etc, anything other than basic shapes. You can make the original pngs larger than you need (as ...Show All

• SQL Server sql 7.0 delayed trigger
