    - Framework version error? A very strange one with a VB.net windows forms thing. Anyone seen anything like this or have any other comments? The history... Straightforward application created in VS 2002 running perfectly happily on machines running version 1.0 of the framework. I come across a bug in the app that (after discussion with MS) is fixed by upgrading to VS 2003 and framework 1.1. I upgrade the app (i.e. open the project in 2003, VS says "Do you want to upgrade?" etc). I upgrade client machines by running the 1.1 framework installer and install the updated app. This was about a month ago. For two weeks the app works fine. Then it goes wrong. Intermittently. There's a particular routine that involves writing data to SQL 2K that it fails on. Meaningless error message. Something about the index is 0 is non-negative and less than the total number of rows (no real detail there because I don't think it's relevant.) Rerun the app and everything is fine. Sometimes. Do something like reinstall the mdac and everything works fine for a while and then collapses again. We fall back onto another machine set up in apparently the exact same way where it works perfectly. This has been the situation for the last two weeks. Tonight a colleague finds an .ini file under documents and settings\username which includes information about what framework is being used (can't remember exactly, but search for .ini modified in the last day and it leaps out). This says that the machine that's going wrong is still using the 1.0 framework. Huh? We have now tried uninstalling the old framework and reran the app. The ini file is now claiming that it's using 1.1. Don't know, as yet, whether this is a fix or not. Were we supposed to uninstall the old framework before installing the new? Have I missed something there? Anyone want to give me odds that the app in question will now work perfectly? -- For real reply address, replace the _surprised_ bits with dots www.realuk.co.uk Tag: RichTextBox and HiperLinks Tag: 62088

    - XP Visual Styles on UserControl in IE (Framework 1.1) I have an IE BandObject that is derived from : UserControl, IObjectWithSite, IDeskBand, IDockingWindow, IOleWindow, IInputObject This control uses DrawThemeParentBackground( this.Handle, hdc, ref rect) to get the parent IE rebar control's gradient background to be drawn under XP. Everything was drawing "fine", up until the point that I added a ToolBar (or a PictureBox, or...) to my bandObject that was docked Left . The Layout is fine - Z-Order correct, etc. -this is only a painting problem related to OnPaintBackground in this class, from all that I can see ;) Now, everything has gone to hell - the background isn't being painted correctly on EITHER a standard toolbar (docked Left) OR a ToolBar-derived class docked Fill. It's CRAZY - even the DIRECTION that MouseOver occurs in (right-to-left, the background paints fine, left-to-right, the background paints each button black in what appears to be the size of the first item in the BandObject - the ToolBar or PictureBox that is docked Left. This seems like it should be fairly straightforward, but there seems to be some kind of interaction between UxTheme and (docking?) I am mucking with the DisplayRectangle of the BandObject (shrinking the width to allow for a small button on the rigt side of the control (a LOT smaller than the area that isn't painting the background correctly). Any pointers would be greatly appreciated - My OnPaintbackground() is implemented as follows: protected override void OnPaintBackground(PaintEventArgs pevent) /* XP Visual Style, only */ { rect = new RECT(pevent.ClipRectangle); try { IntPtr hdc = pevent.Graphics.GetHdc(); int ret = DigitalCollimation.Win32.DrawThemeParentBackground( this.Handle, hdc, ref rect ); pevent.Graphics.ReleaseHdc( hdc); } catch (Exception ex) { Trace.WriteLine( ex.Message + "\r\nat: " + ex.StackTrace ,"OnPaintBackground()"); } } DrawThemeParentBackground() is defined as follows: [DllImport( "uxtheme.dll")] public static extern /* HRESULT */ int DrawThemeParentBackground( IntPtr hwnd, IntPtr hdc, ref RECT prc ); RECT is defined as follows: [StructLayout( LayoutKind.Sequential)] public struct RECT { public Int32 Left; public Int32 Top; public Int32 Right; public Int32 Bottom; public int Width { get { return Right - Left; } } public int Height { get { return Bottom - Top; } } public RECT( int left, int top, int right, int bottom) { this.Left = left; this.Top = top; this.Right = right; this.Bottom = bottom; } public RECT( Rectangle rc) { Left = rc.Left; Top = rc.Top; Right = rc.Left + rc.Width; Bottom = rc.Top + rc.Height; } public static implicit operator RECT( Rectangle rc ) { return new RECT( rc.Left, rc.Top, rc.Left + rc.Width, rc.Top + rc.Height ); } public static implicit operator Rectangle( RECT rc ) { return new Rectangle( rc.Left, rc.Top, rc.Left + rc.Width, rc.Top + rc.Height ); } public override string ToString() { // TODO: change this to use String.Format? return "{ " + Left + ", " + Top + ", " + Right + ", " + Bottom + " }"; } } Tag: RichTextBox and HiperLinks Tag: 62087

    - Asynchronous Server Socket Example Hi All, I am trying to use the Asynchronous Server Socket Example from MSDN ( http://msdn.microsoft.com/library/default.asp?url=/library/en-us/cpguide/html/cpconnon-blockingserversocketexample.asp ) in my C# windows form application. Clients will connect and send a data packet. This server program has to receive packets from multiple clients and relay those packets to another server for further processing. In ReadCallBack function instead of doing Console.WriteLine, I want an event ( Message ) to be sent to the mainform along with the data. So that the Mainform can send this data to other server through already open socket. How can I send (post) event/Message along with the data to the Mainform?

    - Nasty flickering by OnPaint Graphics.Invalidate Using: VS 2003 NET C# for Framework and Framework Compact Trying : Moving a Card (Bitmap) as in Solitare (PC + WinCe) Version on OnMouseMove Problem : The affected drawing Area by Invalidate (or Invalidate(Rectangle)) flickers in a nasty way when repainting. This does not happen in the Solitare (PC + WinCe) Versions a well as in a Card game where I have the C++ Source. The use of an empty OnPaintBackground brings no visable results. The OnPaint calls a Method, which builds a new Bitmap with a local Graphics. When finished OnPaint does one DrawImage Command (flicker). OnPaint is painting to a Panel. Is this a Framework problem ? Can a flicker free Painting only be done with some sort of Win-API. - Goal is for this Class to run with the same code on both Systems. If yes, what would it look like inside a Framework program ? This seems to the last major problem (as of yet) that I have in realising a game programm and it would be very nice if this problem could be solved.

    - [ANN] Xamlon Beta 1 - XAML for Windows.Forms I am very proud to announce the pre-beta release of Xamlon! Xamlon (pronounced "Zamelon," which rhymes with "avalon"), is a XAML runtime library for the .NET Framework 1.1. Xamlon is not a 100% XAML/Avalon compatible library, it was not designed to be, but rather uses some of the same objects and syntax as XAML to provide the same power and capabilities as XAML but for building "Windows.Forms" applications instead. Simply put: "Xamlon is XAML for Windows.Forms" There are several key benefits of using Xamlon today: a.. Application development becomes much more simple and efficient. Xalmon provides a very clean separation between presentation and application logic. b.. Xamlon application run on all of today's .NET Framework 1.1 Windows operating systems: Windows 98, ME, NT, 2000, XP, and Server 2003. c.. Xamlon provides a much simpler migration path to Microsoft's next-generation presentation layer in Longhorn, XAML. This is an early release so we could get it into the hands of developers. There is little to no documentation, but we'll be updating the web site frequently. For pre-beta 1, Xamlon has basic support for the Application object, Window object, and several other controls including GridLayout, FlowLayout, etc. These are very early stage controls, but will allow you to get started. Of course all Windows.Forms controls can be used, third-party controls, etc. Read over the included examples and source code, and we'll be updating the bits frequently! Enjoy... http://www.xamlon.com/ -Paul Colton Tag: RichTextBox and HiperLinks Tag: 61991

I need like a "shrink/stretch to fit" method which understands the aspect ratio bit.... Is it me or is the picturebox control pretty useless...?

    - WindowsForms Data Binding Over Internet Hi Guys, I have been doing a lot of research on what is the best architecture to bind a WindowsForms Application to data across the Internet. Scenario: My company is hosting all data in SQLServer2000 and running IIS/ASPNET The Client applications will be deployed outside our network. Its a typical scenario, but seems like there is too many solutions:) Is Remoting a more efficient way to expose all data manipulation objects, does it need to be synchronized from scratch for all data updating and binding?? Should DataSets be serialized to the client and bound to the forms and will they handle the sync? I saw somewhere that in the SQLConnection string, you can put in something like "Server=http://111.111.222.222/" to connect the DataAdapter over internet..is that true?

    - Borderless form? I would like to create a MFC project (preferable using the Wizard) that has a borderless, menuless window as the main form. Unchecking basically everything in the Wizard still gives me a border and a menu bar. How do I make it borderless & menuless? Thank you, Richard Tag: RichTextBox and HiperLinks Tag: 61960

    - Is there an enumeration for the WM_ messages???? If I overload WndProc(), I'll want a switch() in there to act on different windows WM_ messages like WM_MOUSEMOVE and stuff like that. Trouble is, how do I find the value of these constants? I know, I can hunt around in winuser.h for them, but if I'm a VB or C# guy, that's kind of a roundabout solution. The ".net" way of doing this would be to give me an enum that contained all the values. Is there such a thing? I can't find one. Tag: RichTextBox and HiperLinks Tag: 61958

    - System.Security.SecurityException: Request failed. I'm trying to get my Windows form exe to execute from a web server. Everything works fine on the server itself (my local machine), when I go to any other machine, I get this error. I have used the dotnet Trust An Assembly utility to trust the assembly, and I can browse to the server OK (my local machine). Unfortunately our systems administrators have locked down the security in IE so that it's impossible to add trusted sites, or change any of these settings. I can probably get them to change this, but I'd have to be clear in what I needed changing. Can anybody help. All the samples sem to assume you've got full access to the machine.

    - [ANN]unofficial Extensibility Application Block Hi Folks. Look here for the full details: http://weblogs.asp.net/rosherove/posts/39484.aspx and here for the download: http://workspaces.gotdotnet.com/eap in a few sentences: This block allows you to incorporate plugins into your application with ease. It also allows to easily create plugins for your application if it uses this framework. intro: Extensibility Application Block overview: One of the demands from a successful application is the abilityto easily adept to the needs of its users if and when they change (and they do). Many times, the required changed, or extra features that need to be added require not only pure development work, but also re-compilation of some or all of the application binaries (this discussion does not include web applications, only winform applications). To avoid having to go through this sometimes painful process just to add a simple feature, or fix a simple bug, a new need has grown - to allow extending an existing application without the need to recompile it or even without the help of the original developer. This is how what we know today as Add-ins and plugins were born. When we moved into the world of .Net, we still have the ability to write applications that can be extended by others. However, there is no clear path, a common way, to design and implement such abilities into .Net applications. If you were to go today and try to build an extensible application, you'll be faced with a myriad of articles and HOW-TOs, each explaining the story a little bit differently than it's predecessor. This Application block was created so that we can start and retain a common ground for how such abilities should be built. So that it can be both easy to understand and powerful enough as to be used by the most demanding applications. The solution I present here is based on my experience writing extensible applications in .Net and on all the things I learned while trying to figure out the best way to achieve specific abilities while trying to maintain a generic approach. How does it work? There are 3 basic principles that need to be implemented in order for an application to have plugins: 1. The application needs a way to recognize and communicate with the plugins 2. The Plugins need a way to talk (or sometimes control) the application in which they are hosted 3. The plugins need to be recognized and loaded at runtime into the host application 1. The application needs a way to recognize and communicate with the plugins This application block solves this problem by providing a common interface that all plugins must implement:IPlugin. The principle is actually very simple: Let's say I have a text editing application to which I would like people to be able to add plugins. These plugins should be able to talk to the application in which they reside, AND the application should be able to talk to them. However, since the application does not know in advance what plugins may be available (some of them may only be created in the future!) the application cannot have a direct reference on any specific DLL or class. It needs to support ANY CLASS but it needs to be able to talk to it on pre-known terms. This paradox is solved by the using a COMMON INTERFACE that both the plug in and the application know. This interface is declared in a separate assembly and both the plug in and the application have a reference to that assembly. This interface is what our application will use to communicate with the plug in. Any plug in that will want to attach itself to the app will have to implement this interface or otherwise we won't even try to load it. This interface is called (in this application block) IPlugin. 2. The Plugins need a way to talk (or sometimes control) the application in which they are hosted This application block solves this problem by providing a base class called AppContext. To the Plugins, AppContext is their one and only link to the outside world. Anything they need to do, anything they need to know, they do it through this class. The host application will hold a class derived from AppContext which has specific methods and properties which should be shared with the plugins. the IPlugin interface contains an Init Method which passes an AppContext instance into the plug in, allowing it to hold a reference to it and using it for what it needs. For example, For an Editor application, We can have an EditorContext class which exposes events such as TextChanged and properties such as SelectedText and so on. The plugins can use these properties to manipulate their outside environment . It all depends on how much the developer decides to expose to the plugins using the AppContext class. The AppContext class is also the class that will load and unload the plugins when the application starts and finishes, but for that it uses yet another class from the application block - the PluginProvider classes which I'll now discuss in the next paragraph. 3. The plugins need to be recognized and loaded at runtime into the host application There are many ways in which one can organize and recognize the plugins that their application needs to load. Some prefer to dynamically search all the DLLs in the app directory and find classes that implement the IPlugin Interface. Some prefer to list the required plugins and their type inside the application config file. Some might have a whole different way of doing this which no one has ever thought of before. This application block is built to support whatever method you choose to load your plugins, and it also provides a couple of implementations right off the bat so you can get up and running in no time with your new application. In the extensibility block there are special objects for which the only purpose in life if to find and load plugins. These are called Plugin Providers. Each plug in provider must implement the IPluginProvider interface. There are several providers already build for you. These include the XmlFilePluginProvider, SectionHandlerPluginProvider and DynamicFindPluginProvider. Each of these implements searching for plugins in a totally different way, but because they all support the same interface, they all return a collection of IPlugin object when they are done allowing you to simply choose the method in which to search. Don't find anything you like in there? Feel like you need an extra feature? Simple implement the IPluginProvider interface in your own class and you're free to go. -- Roy Osherove weblog: http://www.iserializable.com Tag: RichTextBox and HiperLinks Tag: 61925

Hello:

Is there any way to show texts as a link on a RichTextBox and receive
LinkClicked events?
The idea is to show a text like "click here" for example.

Thanks

You may want to study the RTF format specification and then insert the
appropriate RTF code by setting 'SelectedRtf':
