• .NET Development to use the NetworkStream::Write() for synchronous sending!?

  Hi ^, i would like to realise a synchronous communication using the NetworkStream::Write() method. In theoretically ("...The Write method blocks until the requested number of bytes is sent or a SocketException is thrown. ...") it is possible to use this function for synchron sending but in fact the Write() method doesn't send the data directly to the remote machine it puts the data into the outgoing network buffer of the PC so doesn't wait for the remote machine's answer. If the outgoing network buffer is full just in this case will be blocked the Write() function. I don't know how can i avoid this buffer or how can i set th ...Show All

• Visual Studio 2008 (Pre-release) Odd exception new to Nov bits

  I have a custom control that is a subtype of MenuItem.  I am getting an odd exception that an element already has a parent.  The stack trace is well within MS code in creating the popup.  The odd part is that a control is regenerating its logical children in the middle of a measure pass while creating the popup window.  My guess is that the popup window is trying to display the same elements that are in the logical tree holding the popup itself somehow.  I have dumped the current MenuItem style and am in the process of trying to use that to locallize the issue.  But, if this is truely odd I am reporting it and i ...Show All

• Visual Studio Express Editions SxS installations of VS 2003, VS 2005, and C# Express 2005 are okay?

  I want to install all of these awesome tools side-by-side.  Is that possible On a different topic, can I install them on XP x64 (or even better, Vista beta x64) Thanks! All the VS products you mention can be installed side by side. They can even be installed side by side on XP x64, where they will run on WOW64. I assume they will also run on Vista, but I'm not sure.
