• Visual Basic vb 2500 tcpListener accepting connections JUST FROM ONE ip address

  Hi guys! I've been using TcpListener and TcpClient classes (I read examples from on line help of Visual Studio 2005). I succeeded in making a tcp server that works quite well. Now I want that this server could accept connections from just one and only IP address (that I choose). Does anybody know how to make it I think it's a simple trick but I'm not able... Thanks for any kind of advise! Zingaro. ehm... sorry: *************** 'se la connessione proviene da un altro ip la ignoriamo e restiamo in ' attesa di un'altra connessione *************** this is italian language and it means: *************** 'if connection is from a different ip address we ignore it and ke ...Show All

• Visual Studio Non-installation question

  I didn't know where to post this question. Sorry. Is there an announced release, or an estimated release date, for Orcas I am going to buy new licenses, upgrading from 2003.net Ent Arch to VS 2005. However, I want to know if I should by the licenses with SA. We dont really ever call support, but would want SA for any upgrades that come out within the 2-year period. Thanks Steve Wyatt Thank you Gabriel. SA- Software Assurance, upgrade advantage etc.. Gives you support and the ability to upgrade to a new product within 2 years of purchase if a new version comes out. Being that Orcas is going to come out later this year, we would probably want to buy the SA so that we will get the new version ...Show All

  My son who is in the army and has little time asked me to write this. I bought for him for Chirstmas a HD-DVD player for his 360 he installed it and it will play DVD's but when he puts in the King Kong it will stop after the titles or not play at all.

• Visual Studio Tools for Office Depolyment on Office XP is not working

  i created a simple excel solution and tried to Depoly on machine running Office XP but is not working. i have also installed PIA's for office xp but it is not working. can somebody help in this. The "hooks" required for VSTO solutions are only available in certain versions of Office 2003. VSTO cannot be used with any earlier Office versions because the required functionality was not in those versions. These is stated quite clearly in the VSTO documentation. You can create standard COM Add-ins for earlier versions of Office, but of course you can use only those features available in those versions. You should ALWAYS test against the target version of Office. Certainly NEVER against an&nbs ...Show All

• Windows Forms ToolTip.Show( string, IWin32Window )

  I'm trying to keep toolTip displayed indefinitely while mouse is over a control. public void Show ( string text , IWin32Window window ) This method is documented to show toolTip "modally" - i.e., keep it displayed until Hid() is called. The doc also states that it "sets" the toolTip text for the control (specified by the argument "window" ) with the arugment "text". I am confused. Is IWin32Window to be the parent window (form) or the target control A related thread's answer suggests it should be the parent form, but that doesn't makes sense as it does not specify the child control to which the method is supposed to set the toolTip text. If the argument is supposed to be the target ...Show All

• .NET Development C++ pointer to referenced C# class

  Hello, I have a "solution" where my C++ project is referencing a C# class. The hope here is to be able to call the C++ function from the C# project and be able the retireive an array of the C# class elements. I was hoping I could do this by simply requiring a pointer to the class object in the C++ function call and then using pointer arithmetic to fill the array in a linear fashion, assuming that the C# address was created with a stackalloc of n class members where n is unknown but < m (buffer). First I'm not sure if this works with C# arrays because I think I remember them being non-linear, and second I get a compiler error when trying to create a pointer to the object in the C++ function parameters list. Is there a better wa ...Show All
