• Visual C# Differneces between c++ and c#!?

  I'm quite new in programing and i started learning c++ but i want to know what are the differences between c++ and c#! (because all examples and learning lessons, from msdn Visual Studio 2005, are written in c#) I know this is a stupid question for all of you but i heard about c# only in Visual Studio. I really need an answer to this question because i don't know what lenguage to learn! Thanks  C# is a newer language with a Java-like syntax and feel to it. C++ is more complex and while much of the syntax is similar to C#, some parts are radically different - I'm thinking especially of C++/CLI vs C# and handli ...Show All

• Software Development for Windows Vista Using data objects from database for holding Workflow/Activity-Properties

  Hello, we are building a end-userfriendly workflow engine (with own designer) (see http://forums.microsoft.com/MSDN/ShowPost.aspx PostID=265499&SiteID=1 ) I have only on question (at the moment). Our activities have some properties, all workflows are derived from our own base workflow (with some properties, for example a workflow object which is sent through the whole workflow). The workflow object is used in IfElseActivities. It is a generic container for any structured data. The data is updated (on demand) by a own EAI layer. So we only want to serialize the object id to the xoml. the object itself is loaded from a da ...Show All

• Windows Forms Position of context menu

  Hi, How can I get the position of context menu Thank's Alexei Normally, the context menu will be shown at the center of the control when the keyboard is used to invoke the context menu of a control (Shift+F10, for example). You can customize the location as follows. Override WndProc in the grid and check if the Message.Msg is WM_CONTEXTMENU (0x007b) If so, check if the Message.LParam is -1, which means this was due to a keyboard message as opposed to the user right-clicking the mouse. Now, call the associated ContextMenu's Show method explicity at the selected row position. Make sure NOT to call the base class after show ...Show All
