• .NET Development sending a custom object to a web service

  hello, i have a web service that containts a method which takes a custom object (say of type food) now i want to to consume this web service from a c# windows app. so when i call this method an error occurs ... knowing that i included a dll class library in both ends(win app and web service) so what can i do whats the exact error I am guessing that you have an object in your DLL that you are trying to pass to the webservice webmethod. Even though these objects have the same name and properties, VS does not see them as the same type (they are different namespaces) and you are getting a type mismatch error. You can't do this. You need to use the object from the VS generated proxy class. ...Show All

• Smart Device Development icmpsendecho() and Icmpapi.h

  Hi all, i have written a little MFC app and am just trying to get an icmpsendecho() to work however i get this error: fatal error C1083: Cannot open include file: 'Icmpapi.h': No such file or directory does anyone know how to get it working i thought that the library was Iphlpapi.lib which i have included in the build as i am using other IPHelper functions. I hope someone can help, thanks Martin Hi Martin, It seems that problem is in library. In Windows CE .NET 4.1 and later, you have to compile with 'Iphlpapi.dll', not linking to Iphlpapi.lib. For more information see article http://msdn2.microsoft.com/en-us/library/ms927411.aspx . I hope it is not very late! ...Show All

• Windows Forms How to access controls on another form

  Hi, I need to access a control that is on a separate form, I have 2 forms, my main form and the details form,so my main form calls my details form, but from my details form I need to access some of the information on the datagrid that is on the main form, I was thinking on using properties but there are too many fields that I need to access, so I was wondering if there is another way.

• Software Development for Windows Vista Using DeviceIOControl under Limited user account

  Dear all, Under Windows XP, the caller of DeviceIOControl must belong to Administrators group or have administrator privilege. But under Vista, it seems no this restriction. Even with limited user account, the DeviceIOControl function still works well without modifying anything about access right. So is this behavior normal or not Thank you. Best Regard, HHWu Under Windows Vista (home/pro editions), the default security policy for optical drives is to allow this access. This is by design. Of course, we provide an easy group policy method to set custom ACLs too, so you can override this in a corporate setting. Thanks, . ...Show All

• Visual C++ LNK2001: using unmanangedC++ in manC++

  Hi, i'm writing a new user-interface for a small software-company. The old interface should be replaced by the new one, the "inner core" should stay. The old program was written in unmanaged C++, but now I'm writing the user-interface in C#, so I have to use class wrappers. While building the managed C++-project (in a solution with the unman.

• SQL Server Migrating a column from ntext to XML

  After SQL Server 2005 migration, I'm trying to change my ntext column to XML type.

Instead the column should be converted to varbinary(max) first and then to XML. Best regards Michael ...Show All

• Game Technologies: DirectX, XNA, XACT, etc. Sprite Collision Detection

  I have a 2D game which I wrote some simple collision detection for, which works like the bounding box example. It detects collisions very well, the problem I am having is moving the objects back so that they are not overlapping. They move 10 pixels a move, so when they collide, they overlap. I want to be able to detect a collision, and move the object that caused the collision back to the point just before they intercept, i.e. not the last position, but somewhere inbetween the last move and this one where the two do not intersect. I hope that makes sense. S Hughes (Clarity Consulting www.claritycon.com) Unfortunately I don't have the exact code to hand. I move it ten pixels a turn, so not moving it if ...Show All
