• Visual Studio 2008 (Pre-release) UserNamePasswordValidator and custom authentication

  Hello, All! I have a service that is based on BasicHttpBinding. It also exposes metadata, so others can see its WSDL. Now I want to apply custom authentication that will be based on HTTP basic athentication. The problem is that my custom validator is not being called, to perform validation ( authentication ), and client gets 403 error. So, I setup my BasicHttpBinding, like so httpBinding.Security.Transport.ClientCredentialType = HttpClientCredentialType.Basic; httpBinding.Security.Mode = BasicHttpSecurityMode.TransportCredentialOnly; Then, I've setup ServiceHost to perform authentication. The code is: //setting the credentials behavior ServiceCredentials sc = new ServiceCredentials(); Validator validator = new Val ...Show All

• Visual C++ trouble with scrollwindow...

  Hi all-- I have a problem with the scrollwindow function. I basically wrote a test program that draws 100 lines of numbers from 0-99 and want to scroll it. But the problem is, when I check the SB_LINEDOWN event and call ScrollWindow(hwnd,0,-cychar,TRUE) it fails to repaint the numbers below what was visible in the window even though I'm drawing all the strings in my WM_PAINT event, not just the ones that would be theoretically visible... here is my code (I apologize...I can't make it stop double spacing the code!!!

• Visual Studio Express Editions New Vs Override ?

  What is the main difference between the New and Override keywords Under what conditions must you use new and when must you use override http://msdn2.microsoft.com/en-us/library/435f1dw2.aspx The new modifier instructs the compiler to use your implementation instead of the base class implementation. Any code that is not referencing your class but the base class will use the base class implementation. http://msdn2.microsoft.com/en-us/library/ebca9ah3.aspx The override modifier may be used on virtual methods and must be used on abstract methods. This indicates for the compiler to use the last defined implementation of a method. Even if the method is called on a reference to the base class it will use the implement ...Show All

• Smart Device Development Building a socket connection - help needed

  Hello, I'm doing some research on a new project and got a bit stuck. Basically I'm trying to get a data connection from a mobile phone to a pc. The connection should be wireless and has to be instantiated by a call. So I want to create the connection by calling the pc. I'm a bit lost here, because I don't know where to search. The mobile and the pc should both be able to send and receive data. A socket connection would also be great, but how do I do that Even just some links to read a little bit about that thing would help a lot. Thanks!

• Windows Forms ListView size limit?

  I'm using a list view to display several properties of a typed list of items, where the typed list normally contains several thousand items. When the size of the typed list is beyond 3 or 4 thousand, I get the following error message: "Collection has reached its maximum capacity." The items that I am trying to list are culled from a larger list of as many as 50,000-60,000. The original data in this scenario is coming from an xml file in the application's startup directory(for when the application's regular database is not available), but I am also using the same process for when the database is live. Code Sample: foreach ( TestInstance a in TestInstances){ lvTestInstances . Items . Add(a . TIID . ToString()); ...Show All
