On Bitmap yes, but I can't find a way through the graphics class. Just seems strange to me that they didn't include a way to do it there.

Try code model generation tools at BoneSoft.com.

What about calling DrawRectangle on a rect that is 1x1 ?

Don't remember if I tried that, but I know you can't draw a line that's one pixel long. I assume rectangle will fail too. I'll try it out though.

Try to draw small dotted line.
Try to draw circle with rect 1x1.
Or finally, set cliprect with size 1x1, and draw line (very bad solution, if upper methods does't work).

Best regards, Alexey.

You can't. That is a .NET 2.0 feature, so you cannot use it from .NET 1.x code.

I think you will have to use P/Invoke code to get to the Win32 Beep call.

Do it the old-fashioned way:

Console.WriteLine("\a");

That didn't work for me, in a WinForms app. Does that require some system volume setting to be non-muted?

Put it in a console app. It's a standard PC speaker beep, not a windows beep.

Hi All
when I am trying to discover visual studio 2005, I got a strange behavior when I am trying to put about 50 button on the form and run the application it makes some flicking in the startup
I don't know why?

Re: Visual studio 2005

This is due to progressive redrawing of parts of a displayed surface. u can use buffering to avoid this flickering.

see Control.DoubleBuffered Property. set this one into true.

Thx, I tried this , DoubleBuffered is protected property and should be used in the sub class
I made an inherited class from class button and used it in my form instead of class Button

see this
class InheritedButton:Button
{
public InheritedButton()
{
this.DoubleBuffered = true;
}
}

but it is still flickers????

Use SetStyle(); and set it in the control that the buttons are getting added to. Also, if you are doing the adding of buttons, instead of the designer, then you should do the following:

// button load event:
public void LoadButtons(string[] buttontext)
{
      this.SuspendLayout();
       ... // button load logic
      this.ResumeLayout();
}

i did but still got the problem

public frmMain()
{
InitializeComponent();
this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
LoadButtons();
}
private void LoadButtons()
{

panContainer.SuspendLayout();
this.SuspendLayout();
for (int j = 0; j < 50; j++)
{
InheritedButton TempButton = new InheritedButton();
TempButton.Cursor = System.Windows.Forms.Cursors.Hand;
TempButton.Size = CellSize;
TempButton.TabStop = false;
TempButton.Text = "?";
TempButton.UseVisualStyleBackColor = true;
TempButton.Click += new System.EventHandler(this.button_ClickGenralHandler);
//TempButton.Location //Coding For locations
panContainer.Controls.Add(TempButton);
}

panContainer.ResumeLayout(false);
this.ResumeLayout(false);
}

and this the code of the Inhireted Controls

class InheritedButton:Button
{
public InheritedButton()
{
this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
}
}
class InheritedPanel : Panel
{
public InheritedPanel()
{
this.SetStyle(ControlStyles.UserPaint, true);
this.SetStyle(ControlStyles.AllPaintingInWmPaint, true);
this.SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
}
}

i still got the problem Smile | :)

Is there a way to get a the name of the logical drive? Not the drive letter, but the name. For example, the drive C: usually appears in under My Computer as "Local Disk ( C: )". How would I obtain the "Local Disk" text?

I love to program!

Give a try to WMI. There are some CP articles about WMI in C#: start here.

If your using C# 2005, you can get this from the DriveInfo[^] class.

"Local Disk" is the drive Type, and is used only because the drive doesn't have a volume label.

All very good answers, however the codeproject reference gets the drive letter, as does the DriveInfo class for C# 2005. Lets say you plug in an external hard-drive and assign it the drive letter (which is the Name property of the DriveInfo class and the ManagementObject["name"] property for WMI) "V:", and you also name it "External hard-drive". How would I get the "External hard-drive" text?

I love to program!

That's the VolumeLabel property of the DriveInfo class.
