To all interested, I have updated nBASS to have WMA Streaming support as well WMA encoding to file and network. Smile | :)

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 Smile | :)

So when can we expect an article detailing what you had to do to expose BASS to .NET? Big Grin | :-D

A link to the BASS homepage in your post would be great as well Smile | :)

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 Smile | :)

Hi
I have tried to insert an image into a RichTextBox component but with no result. I have tried with CreateGraphics and drawn an image into it but when I type over the image, it dissapears.

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.

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);

Calling a C# DLL in C++

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.

How to change namespace for resource file?

tomiga1-Sep-02 1:29

tomiga

1-Sep-02 1:29

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?

Am I doing it right?

Hi,

Well, I guess it's a design quesiton.
I try to write a layout engine with two classes in it. The LayoutPanel class acts as a container for either LayoutPanel or LayoutItem, where LayoutItem is simply an object that stores the width and height of a visible item. and here is my solution:

class LayoutPanel: Component, IContainer
class LayoutItem: Component

is this ok? or better to have an abstract class on top of both (because both of them have widths and heights as attributes).

Thanks Smile | :)

Hey what's up coders...

I guess my question is pretty much the subject but the software I am interested in selling includes a few of the shell32.dll icons! Is this software still sellable or is microsoft gonna get me?

If anyone knows it would be much appreciated if they could get back to me.
Thanks so much.

How to use "win32_find_data" in C# or VB.net?

Segal30-Aug-02 19:45

Initially, I want to fetch or get a file from another machine either through local net or network share, and "win32_find_data" seems to be a good package for this task. But if I want to use it in C# or VB.NET, how should I do it? Or is there any other package I can use? Thanks a lot!

leppie31-Aug-02 2:14

Hi
You will need to define 2 structures in C# first namely, FILETIME and WIN32_FIND_DATA. As:

struct FILETIME { 
    int dwLowDateTime; 
    int dwHighDateTime; 
}

struct WIN32_FIND_DATA {
  int dwFileAttributes; 
  FILETIME ftCreationTime; 
  FILETIME ftLastAccessTime; 
  FILETIME ftLastWriteTime; 
  int nFileSizeHigh; 
  int nFileSizeLow; 
  int dwReserved0; 
  int dwReserved1; 
  string cFileName; //mite need marshalling, TCHAR size = MAX_PATH???
  string cAlternateFileName; //mite need marshalling, TCHAR size = 14
}

[DllImport("kernel32.dll")]
static extern IntPtr FindFirstFile( IntPtr lpfilename, ref WIN32_FIND_DATA findfiledata);

[DllImport("kernel32.dll")]
static extern IntPtr FindClose( IntPtr pff);

public static WIN32_FIND_DATA FindFile(string filename)
{
  WIN32_FIND_DATA fd;
  IntPtr pff = FindFirstFile(Marshal.StringToHGlobalAuto(filename), ref fd);
  if (ppf == IntPtr.Zero) throw new FileNotFoundException();
  FindClose(ppf);
  return fd;
}

Thats should do it, didnt check. Perhaps the TCHAR in the structs, but this should set u well on your way. Obviously, you can Add the other FindFile functions as well.

Maybe there is something in .Net doing the same already???
