There is the UI part and there is virtual key localisation.
About UI, the simplest is to add KeyPress or KeyUp event handlers to your form, so it hooks every key. Then e.KeyCode, or e.Key depending on the handler will return the virtual key code or ANSI code.
Add an imagelist to buttons. And swap images along in event handlers. That will do highlighting.
About localisation, well that's a job that takes time because you'll have to provide cultures keyboard schemes such like AZERTY in French. Which means you have to provide a different set of positioned buttons.
You may of course limit yourself with QWERTY, but ...

Just thought I would make people aware of something I noticed, ok it took me a while to work out why and I had to tell somebody ...
I just noticed that if you use the method BringToFront for a label control the index for the control moves.

I would like to build an application which incoporates 2D graphics. Macromedia / Shockwave jumps to mind in terms of the graphic content I would like to aim for.
I've considered using DirectX but this seems like overkill, and besides there is presently no C# interface to DirectX and I would need to program in C++ to use the SDK (correct me if this statement is wrong, please!).
I'm not out to build a web enabled program and I don't need cross-platform portability.
Does anyone know if there is a 2D graphic engine / library out there which works with .NET? (prefereably C# but C++ is okay).
Thanks in advance!
Only change is constant

Have you looked into using the System.Drawing.2D namespace? That is .NET's interface to GDI+. If 2D is all you're going to do, you may just want to use that.

I've seen on websites that people has done games in C# using DirectX.... if they're dreaming or what, I don't know! 
But I'm pretty sure it is a DirectX for C#!

Many developers have made fine games using VB, thus using C# should be more or less the same.
Of course there are bottlenecks. For instance a .Net application needs at least 4 seconds before it starts (time required for the CLR to compile IL code into assembly code). So don't expect much about time response.
You have at least two options :
- use plenty of ActiveX, for instance the one from Macromedia
- use the System.Drawing assembly, even though you'll end up as with Java 1.0 back 4 years ago : in other words, 1. anything you do requires you to manage your own double buffers, and optimized drawing so the screen does not flicker. 2. the object model is primitive : for instance you cannot draw an arrow. 3. Transparency API ? play with caution, some features will work only on W2K/XP systems. 4. DirectX ? never assume that what works fine on your computer will work on someoneelse's computer. That's the conclusion I made after 2 years of DirectX struggle (where the so-called hardware abstraction at the basis of the whole stuff, is in fact a complete lie). Besides that, manipulating all interface versions will require a full-time job just for it.

You mite want to consider DirectDraw as it will provide wit an overlay layer if available allowing the CPU to be freed up alot. But its only really worth it if you are using alot of drawing.
Alternative is what is said above, using the Shockwave Flash ActiveX control in you application. Search the forum for FLASH , i put some code in a post a while back on how to use the ActiceX control.
Hope this helps

To all interested, I have updated nBASS to have WMA Streaming support as well WMA encoding to file and network. 
Here the link to the source (251kb)[^].
Naturally , you will need bass.dll and basswma.dll from the BASS home page[^].
Here's the changes:
nBASS 0.9.3 (1 September 2002)
- Added WMA streaming support, needs basswma.dll (duh!)
- Added WMAStreamTest with visuals.
- Added FX Parameters property. FX can now be tuned.
- Added GetData(byte[] buffer, int length) to AdvancedChannel.
- Added Stereo FFT flags.
- Added WMA Encoding, woohoo, net radio!
- Added WMAEncoderTest.
nBASS 0.9.2 (29 August 2002)
- Add ProgressInterval property to ChannelBase
- added AdvancedChannel.GetData()
- added StreamTest with visualizers (same as VB.Net) with stereo
- all Debug projects now outputs to a single bin dir in the root. Copy bass.dll & basswma.dll there.
- Increased Progress event to fire even quicker. From 100ms to 20ms.
The source is also nice for seeing a variety of marshalling problems I encountered along the way. You can compare with the docs provided with bass.dll.
To all who finds this usefull, enjoy

So when can we expect an article detailing what you had to do to expose BASS to .NET?
A link to the BASS homepage in your post would be great as well

I'm just recovering from what i feel was some scary marshalling, i'm not sure if everything is even 100%. I will do some testing to see, but I really want to finish the Record part first. I have a very nice a idea for a Voice over IP app doing 2 way encoding from live sources. I would also like to included more documentation, but you know how it goes

If I load a rtf file containing an image it works just fine but how can I include an image programmaticaly?
I included a Com object RichTextBox6.0 and it has an array of ole objects with the add method but I don`t know what to give it as parameters.
Add(object index,object key,object source,object objclass);
Can anyone help me?

You have to do it in Paint event I guess.Maybe you can subclass it and handle Paint yourself.

Yes but if I handle the Paint event then I have to do all the implementation of the text formatting and location and everything else.
|
|
|
|
|
Try this ....
//load the image
System.Drawing.Image myimage = System.Drawing.Image.FromFile("Sample.jpg");
//create a picture box
PictureBox mypb = new PictureBox();
mypb.Image = myimage;
//adjust the size
mypb.SizeMode = System.Windows.Forms.PictureBoxSizeMode.AutoSize;
this.richTextBox1.Controls.Add(mypb);

It works but the text I write is written under the picture.

I write simple web services and add this method to it:
[WebMethod]
public string ReverseString(string message)
{
char[] arr = message.ToCharArray();
Array.Reverse(arr);
message = new string(arr);
return message;
}
When I want to test it in my browser and press Invoke button in new browser his error happend:

Hi all
How does one do this. I have a component that needs a handle to a window on construction, but how can I get the Handle of my Form in design mode??

How is it done? Does anyone have any examples of a C++ app calling a C# DLL?
Can the code in the below zip be converted straight to C#?

|

I just gave a look in MSDN to make sure there was no solution, and I have found that if your managed code exposes COM public interfaces and methods, then yes, it is possible to do it. This does not look easy, and the C# DLL must be rewritten to expose interfaces, and stuff. Just give a look here.

Problem:
During develpoing my application I have changed name of namespace for my main form app.
My app namespace is Analyzer my MainForm namespace is Analyzer.View
Now I am trying to add some ImageList to my MainForm. During running application MissingManifestException is thrown. I have chacked Manifest using Ildasm and there is an entry
<br />
.mresource public Analyzer.MainForm.resources<br />
In my opinion shoud be
<br />
.mresource public Analyzer.View.MainForm.resources<br />
Recompiling doesn't help. Is this mean that MainForm.resX is in wrong (old) namespace? If yes how to change this namespace?
