Re: RoundRect James T. Johnson31-Mar-02 13:03 James T. Johnson 31-Mar-02 13:03  Charles Petzold's Programming Microsoft Windows with C# has an example demonstrating how to create one. Unfortunately the code from the book isn't available on his website, nor MSPress' website so I can't give you his exact code. But I don't think there would be any harm in giving you the algorithm since it is common sense when you think about it First break up your rounded rectangle up into its distinct sections. You have the four sides, and 4 rounded parts. The rounded parts if you put them together form an ellipse. So all you have to do to create your own rounded rect function is to use the DrawArc and DrawLine methods of the Graphics object to position each part where it needs to be.

I provide a function that allows you to set % rounded, just like GDI did. Christian The tragedy of cyberspace - that so much can travel so far, and yet mean so little.

I was hoping I was missing something and would not have to do it manually. I don't understand why they would not have brought RoundRect forward into C#/.NET, it seems like something that would be useful (at least to me). uxtheme.dll and windows XP themes in C# Stephan Johnson31-Mar-02 9:48 Stephan Johnson 31-Mar-02 9:48  okay here is my problem, i have asked this question about a million times, and everybody keeps giving me the same answer... which leads me to the conclution that nobody understands or knows anything about windows XP themes!!! basically if you look at the theme example in MSDN (ms-help://MS.MSDNQTR.2002JAN.1033/dnwxp/html/xpvisualstyles.htm) you see that the example is first of all written in c++, and that they dont expand much on how to do any of this in .NET (e.g. c# and vb.net) now the reason i said that nobody seems to know the answer to this question is that every time i ask it, i get this response ************************** use a manifest file ************************** i knew about using manifest for quite a long time now, that is NOT theming in windows XP. microsoft says that there are new MSLOGO compliancy standards for XP... there are lots of doc's available on the logo site about this, but NONE of them tell you how to do it in .NET!!!! i find this to be extremely unfair as MS wants us (the developers) to use .net it is only right for them to tell us how to stick to the standards that they Set.?!?! am i wrong in asking this? Re: uxtheme.dll and windows XP themes in C# James T. Johnson31-Mar-02 12:46 James T. Johnson 31-Mar-02 12:46  To enable XP Themed controls in a .NET application you need to do two things. First, include the manifest file; second, set the FlatStyle property of your controls to System. If you are creating your own controls then you need to use P/Invoke to obtain the functionality needed for themes.

The page color issue is an acknowledged bug by MS. I'm sure there are other controls where this is a problem though which is why you'll need to P/Invoke to get around it until MS fixes it. akr0 wrote: there is an idea Please do I always look forward to new articles, especially on new topics such as this.

"Wind Up" from Aqualung, Jethro Tull 1971 Manifest compiled into the EXE file Szymon Pusz31-Mar-02 9:18 Szymon Pusz 31-Mar-02 9:18  I know that this topic was discussed, but no-one wrote how to compile manifest as a resource (into the EXE file). So I ask how to do it? Re: Manifest compiled into the EXE file James T. Johnson31-Mar-02 13:26 James T. Johnson 31-Mar-02 13:26  I'm just about to leave again, but I figured I'd throw this out so you can look at it while I'm gone. Assuming you are using VS.NET, add the .manifest file to your project as an "Embedded Resource" and see if that works. If not add it as "Content". This option is accessed in the build property for the file. Let me know if either of those work. I know its possible to do it in VS.NET I just need to remember how.

I think it should be compiled as a Win32 resource and C# compiles it a little bit different (resx). But I'm not sure. Compiling an app in C# with windows dlls STATICALLY linked Szymon Pusz31-Mar-02 6:35 Szymon Pusz 31-Mar-02 6:35  Who knows how to link all DLL's which an C# app need into one EXE file staticaly. In VS C++ there is a choice called "Use MFC in a Static Library" and then the c++ app runs on every system, but how to do it in C#??? Re: Compiling an app in C# with windows dlls STATICALLY linked Michael P Butler31-Mar-02 8:03 Michael P Butler 31-Mar-02 8:03  Which DLL's? If you mean the .NET framework stuff, then you have to distribute the framework with the application. Michael Re: Compiling an app in C# with windows dlls STATICALLY linked Daniel Turini31-Mar-02 9:05 Daniel Turini 31-Mar-02 9:05  If you are referring to .NET framework (you mentioned MFC), well, you can't: you have to redistribute dotnetfx.exe (~20Mb) and install on each client machine. Crivo Automated Credit Assessment Scrolling inbal66631-Mar-02 5:01 inbal666 31-Mar-02 5:01  It's me again... I want to add scrolling to a control I've wrote. Is there a scrolling component like JScrollPane in java, or must I write it all by myself? 10X, Inbal Re: Scrolling James T. Johnson31-Mar-02 13:23 James T. Johnson 31-Mar-02 13:23  There are several classes you can inherit from: ScrollableControl, Panel, or ContainerControl. The documentation recommends inheriting from Panel or ContainerControl but you can inherit from ScrollableControl if you wish.

As far as I could see, these events wasn't accessible to a ScrollableControl like myself. What I used to do back in java was to override Paint and draw only the clip rectangle it gave me. That represented the viewport area out of the big I should have drawn without scrollbars. Is there any component like that (JSrollPane) out there? Inbal Gui controls & Threads inbal66631-Mar-02 4:41 inbal666 31-Mar-02 4:41  Hi, I want to add a large number of nodes to a tree-view, but such operation halts the app. I've tried using a separate thread, but the framework won't allow it, because the thread I've created it's the one that holds the control's windows handle. Is there a way to pass that handle? 10X Inbal Re: Gui controls & Threads James T. Johnson31-Mar-02 13:10 James T. Johnson 31-Mar-02 13:10  First call Begin/End Update on the treeview that should speed up the process a bit because it won't try to redraw after every addtion. Then instead of calling the actual methods on the treview object you need to use the Invoke method on the object, which will marshal your calls to the thread that owns the handle. The documentation will have to be your guide on on using Invoke because I've got another 2-3 days before I'm about to tackle the same thing in my app :-P HTH, James Sonork: Hasaki "I left there in the morning with their God tucked underneath my arm their half-assed smiles and the book of rules.

'Invoke' calls my method on the main thread, which means that the app stucks all the same. I need means of calling AddNode from a completely different thread, so that my main thread can still listen to user mouse clicks etc. Inbal Re: Gui controls & Threads 21-Apr-02 23:04 21-Apr-02 23:04  you should go down to TVN_GETDISPINFO in a WndProc override What is the code for exit inVC#?
