• BhuttCrackSpackle retrieving network interface IP addresses

  Hi, I need to overwrite the DSCP byte for outgoing packets on a given socket. Currently, I am enumerating interfaces with TcEnumerateInterfaces() and plan to use TcAddFlow/TcAddFilter() to add a flow with a new QOS_DS_CLASS object. However, I need to match the interface from TcEnumerateInterface to the one the socket is bound to by comparing IP addresses, and here I am running into a problem, namely that I don't seem to be able to interpret the NETWORK_ADDRESS correctly. The address I am trying to interpret is of type NDIS_PROTOCOL_ID_TCP_IP, so I casted it to a NETWORK_ADDRESS_IP structure, but the ulong representing the IP is coming back as 0xCCCCCCCC. My alternative that I haven't tried yet is to use the IPHelper API to find the interf ...Show All

• SQL Server Management Studio generics: T Create<T>() where T : MyClass, new(...)

  Is there a way to enforce a non default constructor And if not, why not ! I wrote a class that implements a constructor that is in need of an XmlDocument as a parameter. Several other classes inherit from this base class. Now I would like to write a generic create method that instantiates one of the child classes and sets some base properties: class MyClass { public MyClass(XmlDocument xmlDoc) { ... } public ElementName { get { .. } set{ ... } } } class ChildClass1 : MyClass { ... } class ChildClass2 : MyClass { ... } class MyClassFactory { ... public T Create<T>(XmlDocument xmlDoc) where T : MyClass, new() { T myClass = new T(xmlDoc); ... } ... } Obviously that does not work because the generic all ...Show All

• Wedgetail ListView Selected Item Move to Another Control

  When I select an item in the list view I'm using the SelectedIndexChanged procedure to run some code. At the end of the code I would like the cursor to be be put in TextBox TB1. When I use TB1.Focus() the system still keeps the items in the ListView Selected to have the focus. If through the code I change the selecteditem everything works. The problem is when the user clicks the item. Thanks for everyones assistance. Hi, According to what you said, it's quite nature.

• rwbogosian Caret Position SelectionStart, Simple?

  This should be simple... I have a maskedtextbox on a form, and I've added an OnEnter event which I want to set the caret position to zero (it defaults to the end). From what I've read you should use the SelectionStart Property to do this, but I can't get it to work. In the debugger it seems to reflect the correct selectionStart position but even though I set the value the caret doesn't get repositioned. I've also tried setting the selection length to various numbers along with the selectionStart... Any help would be greatly appreciated. It works fine with me....... I dont know why its not workign for you. Try it in a seperate application, Use TextBox on Form and then on UserControl see behaviors. I hope this will w ...Show All

• Dwatney Some questions about functionality in VS2005

  Hi, just some questions about VS2005: 1. Is there a possibility to add the //, which are added with the comment out button, at the beginning of the line 2. Is there a function which finds the missing using directives and adds them on request (Like the 'Fix imports' function in netbeans, for those who know it) 3. Is there a way to add new tabs (e.g. when opening a file) at the _end_ of the tabs row and not at the beginning Thanks for any help on any of there questions!

• Andrea Williams What database are you using?

  Daer Srs. I actually would like to know what databases do you usually use.. or what would you recomend for a not very simple winapp how do you mean "what database do you usually use" Everyone has their own way/product they use. It also depends on the type of application. Please tell us the type of application you are creating. Some people use Xml to store data locally, which is ideal for a mini mini database some people use MS Access locally to store data instead of using SQL Server - this would be a better approach if you are not doing major database stuff some people use SQL Server because not only is it industry standard but because it is good at managing and processing large amounts of data, which has more poten ...Show All
