خطا در نمونه سازی از یک کلاس
سلام دوستان وقت بخیر.
من یه کد وی بی پیدا کردم برای نوتیفیکیشن اونو تبدیل کردم به سی شارپ حالا یه مشکلی دارم که کد خطاشو میزارم اینجا.
این کدهای کلاس:
public class ExtendedControl :Control
{
ExtendedControl()
{
SetStyle(ControlStyles.AllPaintingInWmPaint, true);
SetStyle(ControlStyles.OptimizedDoubleBuffer, true);
SetStyle(ControlStyles.UserPaint, true);
SetStyle(ControlStyles.SupportsTransparentBackColo r, true);
}
bool m_isTransparent = false;
[Description("Gets or sets the 'real' transparency of the control.")]
public bool IsTransparent
{
get { return m_isTransparent; }
set
{
m_isTransparent = value;
if ((value == true))
{
this.BackColor = Color.Transparent;
}
Invalidate();
}
}
protected override void OnPaintBackground(System.Windows.Forms.PaintEventA rgs e)
{
base.OnPaintBackground(e);
if ((IsTransparent))
{
if (!(Parent == null))
{
int myIndex = Parent.Controls.GetChildIndex(this);
for (int i = Parent.Controls.Count - 1; i >= myIndex + 1; i += -1)
{
Control ctrl = Parent.Controls[i];
if ((ctrl.Bounds.IntersectsWith(Bounds)))
{
if ((ctrl.Visible))
{
Bitmap bmp = new Bitmap(ctrl.Width, ctrl.Height);
ctrl.DrawToBitmap(bmp, ctrl.ClientRectangle);
e.Graphics.TranslateTransform(ctrl.Left - Left, ctrl.Top - Top);
e.Graphics.DrawImage(bmp, Point.Empty);
e.Graphics.TranslateTransform(Left - ctrl.Left, Top - ctrl.Top);
bmp.Dispose();
}
}
}
}
}
}
}
اینم کد کلاس نوتیفیکیشن منیجر:
class NotificationManager
{
Timer tmrAnimation;
Timer tmrDelay;
//Control where the message will be displayed.

//Some property variables.

//Why paint in bitmap? because we will set its opacity and paint it on the control later with a specified alpha.

//Now, draw the content on the control.

}
که روی خط ExtendedControl displaycontrol = new ExtendedControl(); این خطا رو میده
Error 1 'WindowsFormsApplication2.ExtendedControl.Extended Control()' is inaccessible due to its protection level D:\WindowsFormsApplication2\WindowsFormsApplicatio n2\NotificationManager.cs 16 42 WindowsFormsApplication2
ممنون میشم راهنماییم کنید بدجور لنگ اینم.
