Controls in C# David K12-Dec-02 11:36 David K 12-Dec-02 11:36  Hi Is there any way to create a control in C# and use it in non .Net (MFC 6) program? thanks Re: Controls in C# Christian Graus12-Dec-02 18:11 Christian Graus 12-Dec-02 18:11  Um... no. Christian No offense, but I don't really want to encourage the creation of another VB developer. - Larry Antram 22 Oct 2002 C# will attract all comers, where VB is for IT Journalists and managers - Michael P Butler 05-12-2002 Again, you can screw up a C/C++ program just as easily as a VB program. OK, maybe not as easily, but it's certainly doable. - Jamie Nordmeyer - 15-Nov-2002 Re: Controls in C# James T. Johnson13-Dec-02 1:06 James T. Johnson 13-Dec-02 1:06  Yes, but it isn't cut and dry and NOT supported by Microsoft (in the early beta's it was possible, but was later removed and now the only supported non-.NET host is IE). Essentially you have to implement all the COM interfaces that a standard ActiveX control would implement. I believe there is an article here on CP which explains what you need to do, Exposing Windows Forms Controls as ActiveX controls[^]. You will probably have to do some conversions between the class names used in Beta 1 and the ones that made it into 1.0 (for example System.WinForms is now System.Windows.Forms and System.WinForms.RichControl is now System.Windows.Forms.Control or System.Windows.Forms.UserControl). James - out of order - Re: Controls in C# grv57513-Dec-02 2:19 grv575 13-Dec-02 2:19  It sounds like you would just have to implement the COM registry stuff yourself. MS probably pulled this feature to get away from having to support older systems and concentrate solely on a .NET push. After all activex is just an exe done in COM and it's rather easy to write com controls in assembly language once you see which registry entries + class interface methods are expected.

The response I heard was it was pulled because they didn't have time to test all possible permutations of how it would be used. By only supporting IE as the host, they had much less they needed to test/debug. At the time they said the feature would be coming back later, after it could be tested.

I guess I have to cast the EventArgs to something very clever - but what, and how to find out? TIA Peter If I could find a souvenir / just to prove the world was here   [sighist] Re: ListView: Which item doubleclicked? leppie12-Dec-02 12:21 leppie 12-Dec-02 12:21  From MSDN (ItemActivate event): The ItemActivate event occurs when the user activates one or more items in the ListView control. The user can activate an item with either a single-click or double-click, depending on the value of the Activation property, or with the keyboard. From within the event handler for the ItemActivate event, you can reference the SelectedItems or SelectedIndices properties to access the collection of items selected in the ListView to determine which items are being activated. Not sure is this what you are looking for...

James T. Johnson13-Dec-02 1:31 James T. Johnson 13-Dec-02 1:31  Use the GetItemAt method of the ListView passing in the current mouse position in client coordinates (you can get the position by the MousePosition static property of the Control class).

Jassim Rahma Re: VS on Linux platform David Stone12-Dec-02 11:35 David Stone 12-Dec-02 11:35  Well... You can run the Shared Source Common Language Infrastructure[^] on FreeBSD and MacOSX.

Re: is connected Not Active12-Dec-02 11:58 Not Active 12-Dec-02 11:58  Make sure your help notes include that. When using this application you must ping or connect to a website to make sure are connected. There is an API that escapes me that tells if the machine has an active connection. You could also create a WebRequest and try attempting to connect to a well know site then have your application respond accordingly. Re: is connected grv57513-Dec-02 2:02 grv575 13-Dec-02 2:02  I believe the only api availiable for online status is for dialup connections. Won't help for broadband. The best solution is just to ping an outside server. Re: is connected Not Active13-Dec-02 2:55 Not Active 13-Dec-02 2:55  The same way the network status systen tray icon is updated when you log off or pull your network connection. I just can't remember the function call now. I found it once for a project but never used it. Re: is connected Shaun Wilde13-Dec-02 3:54 Shaun Wilde 13-Dec-02 3:54  I think the API you are thinking of is 'InternetGetConnectedState' all part of the WinInet library Technically speaking the dictionary would define Visual Basic users as programmers. But here again, a very generalized, liberal definition is being employed and it's wrong - just plain wrong - Tom Archer 5/12/02 Time fredza12-Dec-02 10:04 fredza 12-Dec-02 10:04  Hello, How to set the SystemTime ?

Re: Finding a Window Stephane Rodriguez.12-Dec-02 10:02 Stephane Rodriguez. 12-Dec-02 10:02  If you simply lookup this forum, you'll probably find a dozen answers for this question. Beyond that, why should there be anything like xxxWindow method or function call in the .NET API ? Have you heard or read about the "window" term in the .NET doc ? Answer : windows are hidden behind the FCL. You've got to get used to work without explicit windows. Re: Finding a Window Not Active12-Dec-02 10:12 Not Active 12-Dec-02 10:12  The original question was .Does C# and or .NET provide a function similiar to the WinAPI FindWindow or FindWindowEx methods?: He was not looking for an exact one to one match.
