• Visual C++ Can I use POSIX threads in a atl STA project

  I have a library which uses pthreads inside of it. Can I use this library safely in a single threaded apartment project. If I can't what are my options . I want to use this library for building a com component. Thanks I don't know the implementation details or pthreads; but, there's no problem with multiple threads on an STA object; you just have to make sure you don't do anything with any of your STA object's members while running in one of those threads--all member access to your STA object should be done with the STA thread. ...Show All

• Visual Studio 2008 (Pre-release) ASP.NET Client -WebReferences Changed The Interface

  public interface IMyService { [OperationContract] double Add(double n1, double n2); } -> public void Add( double n1, bool n1Specified, double n2, bool n2Specified, out double AddResult, out bool AddResultSpecified ); I am receiving the same problem. On the same machine, I compile the "Getting Started" WCF sample solution through VS2005. I then use VS2003 to try and consume the web service through a VB.NET client I created.

• Visual Studio Express Editions Question about "sealed"

  Hi all I have read the documentation (see below) but i'd like if anybody could explain better, in a practical context, the actual benefits of declaring a class "sealed". For example why it could be fine to prevent inheritance of a class thanks in advance for any help/info about the above! -- from MSDN documentation --- sealed (C# Reference) The sealed modifier can be applied to classes, instance methods and properties. A sealed class cannot be inherited. A sealed method overrides a method in a base class, but itself cannot be overridden further in any derived class. When applied to a method or property, the sealed modifier must always be used with override (C# Reference) . Use the seale ...Show All

• Smart Device Development Application loses focus when closing a Form - but only on one Form it happens...

  Hi all, I have this strange problem/issue that I have had bothering me for a while now. I have an application where the users browses through Forms to perform various bits of functionality, and then closes the form to return back to the previous form (the Form from which it was openned), and the Focus is right back with the Form that openned the closed Form (if you know what I mean :)). Now this all works fine in my application apart from in one place, where when the called Form is closed, the calling form (or my Application even) doesn't get focus back until the 2nd tap on the application with the pen. The Windows start button and Input control on the MainMenu are focused and can be activated from the first click on them, but not my appli ...Show All

• Windows Forms How do I create an object from a row in a DataGridView / BindingSource?

  I would like to create an Object (say Client) from the currently selected row in a DataGridView. The DataGridView's DataSource is a BindingSource, for which the DataSource is a DataSet containing a single Table of Clients. I have been advised to use the BindingSource.Current property to get the selected item (or row), rather than the DataGridView. I have tried the following: DomainClient c_client = (DomainClient)c_bindingSource.Current; which results in an exception. How can I get around this Thanks in advance, JackStri. Remember that BindingSource , in your case, is binded to a DataSet . Therefore the current object would be a DataRow in the data set. You'll therefore need to conver the dat ...Show All

• Visual Studio Express Editions how to get hardware IDs of system

  how to get Hardware ID,serial no,model no of pc Harddisk,Processor,motherboard etc.... you could use WMI for this approach. http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=845223&SiteID=1 be sure to add a reference to System.Management and import the namespace.
