• .NET Development How to recover socket after failed SSL negotiation?

  There are so few examples and direction I need to ask this question. I am implementing SSL over FTP. The FTP protocol is such that a a clear channel sequence of requests are made in clear text, and the server responds to each in clear text. Then simultaneously AuthenticateAsServer and AuthenticateAsClient are called. If there are certificate issues at the server, the server will fail. The client hangs indefinitely. I would have thought the AuthenticateAsClient would have failed as well, but this does not happen. At this point, as per FTP protocol, it is inappropriate for the server to send an unsolicited response. Yet this seems ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Spectrum Analyzer for Real time Audio.

  I have a directX application which reads real time audio from a sound card (mic) and calculates FFT for it. Frequency of sound per .5 second. I need to create a spectrum Analyzer kind of component.

• Smart Device Development Eureka

  Hi,     I m trying to access the internet in the asynchronous mode for wince 4.2 smartphone 2003 SE using VS2005. I have already tested the synchronous mode for operation on the emulator. However if I try to download the same URL in asynchronous mode, InternetOpenUrl() API call fails with error code as ERROR_IO_PENDING. I have tried out almost all the code samples on the internet (their happen to be only a couple of them it seems). But still this error is very unexpected as the same URL opens in the synchronous mode. Pls take a look at my code here : the url i pass to this function is http://10.20.40.1/foo.html Any help on ...Show All

• Visual C++ Installing a driver ?

  Hi all. I have a C# program which I install with an MSI I create with 'Advanced Installer'. The version I have does not allow me to install a driver. Obviously, my app needs .NET, so I wrote a Win32 windows app, which provides a splash screen, installs the .NET framework, etc. I'd like to also install a .inf file ( a driver ) in this code. However, googling 'C++ install driver' gives a ton of useless matches ( I'm usually good at google but not this time ). Does anyone know how I can install a driver programatically Thanks This worked back in the days of NT4 (without error checking): const char* pathToDriver = "c:\my ...Show All

• Visual Studio Different file types between Vss6 and Vss2005

  Hi, I'm currently evaluating Vss2005 client with some existing databases created with Vss6. I have detected a strange issue: a text file appears with Vss6 client as a text file (quite normal), whereas it appears as a binary file in Vss2005. In the same way a binary file appears in Vss6 as binary and has unicode8 in Vss2005 (please note that I have already tried to deactivate the automatic file file type recognition). It sounds like Vss6 and Vss2005 are not really compliant on that point ... For information I'm using Vss2005 v8.0.50727.42 (french). Thanks for sharing your experience. Cheers, Frederic. ...Show All
