Hello --

http://www.unicode.org/charts/PDF/U1D100.pdf[^]

Thank you for reading my thread.I have read several books on rendering with Unicode. But in looking at the Unicode Music Fonts chart (See link above) it would seem that in some instances, there are several Unicode numbers that must be combined to create a musical example. If this is true, is not Unicode in this case a kind of GDI+ ?

Please look at the following example below:

http://www.unicodemusic.bravehost.com/[^]

Can someone please provide an example of how the above musical example can be done in Unicode? If so this would be most appreciated. I can't find anyone who understands how this can be done.

Thank you so much and I hope you are having an excellent day! Smile | :)

captuting mouse position.

7-Oct-04 7:38

Unicode is a way to encode text - nothing more. It comes in 16-bit and 32-bit flavors.

What renders characters to the screen is a different subject, something you don't really need to worry about. What you do need to worry about is finding a font that actually contains the characters for the musical notes. To date I've not seen any (then again, I haven't looked specifically for fonts with these characters defined). Just because glyphs are defined for certain code points doesn't mean a font has to contain them.

To enter Unicode code points in C# (many other managed languages use the same syntax), use \uXXXX where XXXX is the hexadecimal number of the code point.

in your OnMouseUp event of your control, add the following code:

MessageBox.Show("X: " + Cursor.Position.X + ", Y: " + Cursor.Position.Y);

You can use the Cursor.Position property to find the current location of your mouse cursor on the screen.

After retrieval of the mouse position as described by the preceding posting use the PointToClient method of your Panel to convert the mouse position from screen coordinates into client coordinates of your Panel.

Hi guys i got the question keep asking but haven't got the right answer yet.
The question is how can make the progress bar working with long run process using threading. I have 1 form, a long run process method e.g
public void LongRunProcess(), and a progress bar. i would like to make the progress bar run based on the time of the LongRunProcess(), ie. when the process the progress bar show 100% complete and the UI won't freeze. Anyone help me to do so. Thank you

You have haven't said what the problem is, other that a general "UI freezes", all we can do if refer you to examples of other Progress Bar controls. Check out Building a Progress Bar that Doesn't Progress[^] for a threaded Progress Bar. The code is in VB.NET, but can easily be translated to C#.

This is simply a trick.If are getting good suggection i recommand you to go ahead with that.

I can suggest you one thing. Create a custom event which will increase the value of the progress bar. I mean you need to fill the progress bar without any user interaction or something. Call this event in different stages of your thread execution.
For eg: You have a thred which will execute 100 lines of code. You can call your custom event in alternate 10 lines. You can step the status bar value by 10 in your event handler.

Here is my code but i don't know how to make this work

private void btnUpdate_Click(object sender, System.EventArgs e)
{
timer1.Start();
Thread t = new Thread(new ThreadStart(GetWebServices));
t.Start();
}

//Update the progressBarFormAction this will be put in tick event of timer1
private void UpdateProgressBar()
{
if(prgBar.Value!=prgBar.Maximum)
prgBar.PerformStep();
}

//Long run method
public void GetWebServices()
{
//int noWs =0;
com.strikeiron.www.StrikeIronDirectoryService service = new com.strikeiron.www.StrikeIronDirectoryService();
com.strikeiron.www.LicStatus lic = new com.strikeiron.www.LicStatus();
com.strikeiron.www.RespStatus res = new com.strikeiron.www.RespStatus();
com.strikeiron.www.WebServiceInfo [] list =null;

try
{
list = service.GetAllPublicServices(this.siLicense,out res,out lic);

}
catch (System.Net.WebException)
{
MessageBox.Show(this,"Internet connection error");
}

System.Threading.Thread.Sleep(100000);
}

You can't monitor the progress of the call to .GetAllPublicServices. Also, by putting the progress increment in a timer, you're not showing the actual progress of the call, but of the timer itself. You best bet to to use a progress bar class that shows something is going on, but not actault progress towards a "100% goal". The link I gave you is a perfect example of this.

how to stream video files via web application(asp.net)

6-Oct-04 19:50

You should start by reading the .NET Framework SDK, such as the section entitled Interoperating with Unmanaged Code[^]. This explains interop'ing with COM servers, clients, and unmanaged functions exported from native DLLs.

There's also a lot of other articles on this site discussing .NET Interop.

hey guys,

if anyone has idea about how to stream a video via asp.net application using flash player or windows media palayer pls post me related site,tutorial or code sample as soon as possible.

best regards from mohan

You should ask this in the ASP.NET forum.

Honestly, ASP.NET shouldn't stream the video. There's already servers that do that, such as Windows Media Server on Windows 2000 Server and Windows Server 2003.

my drawing disappear

i've a private void drawGraph(PaintEventArgs pe) function and i triggle it only after i click the button. However, after i click the button,if i minimise my form or drag it away from view, the drawing disappear. why is it like this?

Heath Stewart6-Oct-04 19:47

6-Oct-04 19:47

You need to override OnPaint and perform your painting operations using the PaintEventArgs.Graphics object passed to the method. Also, don't forget to call base.OnPaint before starting your painting (typically).

If you don't do this, when the form gets invalidated (such as minimizing it) then it will not get repainted.

There are many articles about custom drawing on this web site and you should try searching for some using the search box below the logo at the top of every page.

hi,thanks for the reply.
(1)However, now i'm using a function to draw my graph.i did not use "PaintEventArgs e" but i did this way
private void drawGraph()
{
MessageBox.Show(""+ getValue);
Graphics myGraphics = CreateGraphics(); //instead of e.Graphics;
Pen myPen = new Pen(Color.Black,1);

............
} because i need to call this function when button1 is click. So how should i go about doing the override OnPaint and base.OnPaint?
(2)After button1 is click, how do i display the graph onto a PictureBox instead of display it onto the form?

Heath Stewart7-Oct-04 7:28

Firs tof all, MessageBox.Show is the worst way to debug an application. Set a breakpoint on the line you want and in Visual Studio hit F5 while doing a debug build. That's real debugging and can yield far more valuable data than MessageBox.Show.

Define drawGraph like so (and please following .NET naming guideilnes when developing, which is documented in the .NET Framework SDK):

static readonly Pen BlackPen = new Pen(Color.Black, 1);
private void DrawGraph(Graphics g)
{
  // ...
}
 
protected override void OnPaint(PaintEventArgs e)
{
  base.OnPaint(e);
  if (graphEnabled) DrawGraph(e.Graphics);
}
 
private void button1_Click(object sender, EventArgs e)
{
  graphEnabled = true;
  Refresh();
}

I'm assuming here that button1 works as an enabler. When you call Refresh the client area is invalidated and redrawn immediately, meaning that OnPaint gets called. As long as graphEnabled is true in this example, any invalidated of your control (i.e., when a portion is hidden) will be redrawn with the graph.
