Heath Stewart: I am new to windows programming. Can you show me how to use the SHAppBarMessage function via P/Invoke? Regards Thomas

Is it possible from C# to hide the windows taskbar? And how do I change the DPI settings? (I want to force 96 DPI, Small Fonts). Thanks Regards Thomas

Hi Heath Stewart The algorithm is not the problem. But how do I fill the figure? (the C# GDI+ code is my problem) Regards C#

Hi. Can someone show me how to fill 50% of the below drawing with a solid color. From buttom to top. Thanks Regards r9 The drawing: private System.Drawing.Graphics graphicsObj = null; private System.Drawing.Pen penBlackWidth1 = new System.Drawing.Pen(System.Drawing.Color.Black,1); private Point[] curvePoints = null; private SolidBrush lightGrayBrush = new SolidBrush(Color.LightGray); private Point point1; private Point point2; private Point point3; private Point point4; private SolidBrush blackBrush = new SolidBrush(Color.Black); ................................................... try { graphicsObj = e.Graphics; graphicsObj.DrawLine(penBlackWidth1, 45, 20, 175, 20); graphicsObj.DrawLine(penBlackWidth1, 45, 20, 45, 120); graphicsObj.DrawLine(penBlackWidth1, 175, 20, 175, 120); graphicsObj.DrawLine(penBlackWidth1, 45,120,90,160); graphicsObj.DrawLine(penBlackWidth1, 175, 120, 135, 160); graphicsObj.DrawLine(penBlackWidth1, 90, 160, 135, 160); graphicsObj.DrawLine(penBlackWidth1, 465, 335, 490, 335); graphicsObj.DrawLine(penBlackWidth1, 580, 335, 605, 335); graphicsObj.DrawLine(penBlackWidth1, 465, 335, 490, 335); graphicsObj.DrawLine(penBlackWidth1, 580, 335, 605, 335); graphicsObj.DrawLine(penBlackWidth1, 473, 345, 483, 345); graphicsObj.DrawLine(penBlackWidth1, 473, 345, 478, 335); graphicsObj.DrawLine(penBlackWidth1, 483, 345, 478, 335); graphicsObj.DrawLine(penBlackWidth1, 587, 345, 597, 345); graphicsObj.DrawLine(penBlackWidth1, 587, 345, 592, 335); graphicsObj.DrawLine(penBlackWidth1, 597, 345, 592, 335); point1 = new Point(592,335); point2 = new Point(597,345); point3 = new Point(587,345); point4 = new Point(592,335); curvePoints = new Point[] { point1,point2, point3, point4 }; graphicsObj.FillPolygon(blackBrush, curvePoints, FillMode.Alternate); point1 = new Point(478,335); point2 = new Point(483,345); point3 = new Point(473,345); point4 = new Point(478,335); curvePoints = new Point[] { point1,point2, point3, point4 }; graphicsObj.FillPolygon(blackBrush, curvePoints, FillMode.Alternate); } catch (Exception ex) { MessageBox.Show(ex.Message); }

Hi Shree Can you give an example?

correction: if 50%, then only 50% of the drawing must be filled with the color.

I have this drawing: private System.Drawing.Graphics graphicsObj = null; private System.Drawing.Pen penBlackWidth1 = new System.Drawing.Pen(System.Drawing.Color.Black,1); private Point[] curvePoints = null; private SolidBrush lightGrayBrush = new SolidBrush(Color.LightGray); private Point point1; private Point point2; private Point point3; private Point point4; private SolidBrush blackBrush = new SolidBrush(Color.Black); ................................................... try { graphicsObj = e.Graphics; graphicsObj.DrawLine(penBlackWidth1, 45, 20, 175, 20); graphicsObj.DrawLine(penBlackWidth1, 45, 20, 45, 120); graphicsObj.DrawLine(penBlackWidth1, 175, 20, 175, 120); graphicsObj.DrawLine(penBlackWidth1, 45,120,90,160); graphicsObj.DrawLine(penBlackWidth1, 175, 120, 135, 160); graphicsObj.DrawLine(penBlackWidth1, 90, 160, 135, 160); graphicsObj.DrawLine(penBlackWidth1, 465, 335, 490, 335); graphicsObj.DrawLine(penBlackWidth1, 580, 335, 605, 335); graphicsObj.DrawLine(penBlackWidth1, 465, 335, 490, 335); graphicsObj.DrawLine(penBlackWidth1, 580, 335, 605, 335); graphicsObj.DrawLine(penBlackWidth1, 473, 345, 483, 345); graphicsObj.DrawLine(penBlackWidth1, 473, 345, 478, 335); graphicsObj.DrawLine(penBlackWidth1, 483, 345, 478, 335); graphicsObj.DrawLine(penBlackWidth1, 587, 345, 597, 345); graphicsObj.DrawLine(penBlackWidth1, 587, 345, 592, 335); graphicsObj.DrawLine(penBlackWidth1, 597, 345, 592, 335); point1 = new Point(592,335); point2 = new Point(597,345); point3 = new Point(587,345); point4 = new Point(592,335); curvePoints = new Point[] { point1,point2, point3, point4 }; graphicsObj.FillPolygon(blackBrush, curvePoints, FillMode.Alternate); point1 = new Point(478,335); point2 = new Point(483,345); point3 = new Point(473,345); point4 = new Point(478,335); curvePoints = new Point[] { point1,point2, point3, point4 }; graphicsObj.FillPolygon(blackBrush, curvePoints, FillMode.Alternate); } catch (Exception ex) { MessageBox.Show(ex.Message); } I want to fill the drawing with a color. From buttom to top. BUT the drawing must be filled accourding to a percent. Is 50%, then only 50% of the drawing must be filled with the color. Natural the fill must newer come outside the drawings edge. Any help? Thank

I have some Mdiclient who's windowsState is "Maximized" and where minimumBox and maximumBox is set to false. ControlBox is set to false. FormBorderStyle is "FixedToolWindow". But still there is 3 icons in top right, when the mdiClient is Maximized.... And there is also a restore icon in top left. How do I remove these icons, so that my MdiClient always is Maximized?? See: http://csharp.users.whitehat.dk/mdi.jpg Thanks

I have a pictureBox on my Form. Then I use the graphics object from the PictureBox_paint event: .. graphicsObj = e.Graphics; ..

You are genius :-) With all your help, I am getting better and better at understanding GDI+. Thanks

It is possible to put a tooltip on a GDI+ figure? (on mouseOver) The tooltip1.SetToolTip() method takes in a System.WindowsForms.Control, but there is no overload for a GDI drawing ?

WiB: Is it possible to make the mouse cursor = Cursors.Hand if the the user point the mouse inside my figure ? formGraphics.DrawLine(myPen, 4, 4, 50, 4); formGraphics.DrawLine(myPen, 4, 4, 4, 100); formGraphics.DrawLine(myPen, 50, 4, 50, 100); formGraphics.DrawLine(myPen, 4, 100, 27, 120); formGraphics.DrawLine(myPen, 50, 100, 27, 120);

Thanks again

WiB: Thanks. It works perfekt. How do you know in which order to put the Points?? Eks: Point[] points = { new Point(4, 4), new Point(50, 4), new Point(50, 100), new Point(27, 120), new Point(4, 4), new Point(4, 100)}; Won't fill the figure correkt.

Can anyone show me how to fill this figure with a blue color? System.Drawing.Graphics formGraphics = null; System.Drawing.Pen myPen; formGraphics = pictureBox7.CreateGraphics(); myPen = new System.Drawing.Pen(System.Drawing.Color.Black,1); formGraphics.DrawLine(myPen, 4, 4, 50, 4); formGraphics.DrawLine(myPen, 4, 4, 4, 100); formGraphics.DrawLine(myPen, 50, 4, 50, 100); formGraphics.DrawLine(myPen, 4, 100, 27, 120); formGraphics.DrawLine(myPen, 50, 100, 27, 120); Maybe with the FillPolygon method.

jdunlap: You can email me the code on: java2@mail.dk Thanks

I have a figure that I want to fill with black color, but it don't work!! private void button11_Click(object sender, System.EventArgs e) { System.Drawing.Graphics formGraphics = null; System.Drawing.Pen myPen; formGraphics = pictureBox7.CreateGraphics(); myPen = new System.Drawing.Pen(System.Drawing.Color.Black,1); formGraphics.DrawLine(myPen, 4, 4, 50, 4); formGraphics.DrawLine(myPen, 4, 4, 4, 100); formGraphics.DrawLine(myPen, 50, 4, 50, 100); formGraphics.DrawLine(myPen, 4, 100, 27, 120); formGraphics.DrawLine(myPen, 50, 100, 27, 120); SolidBrush Brush = new SolidBrush(Color.Black); Point point1 = new Point(4, 4); Point point2 = new Point(50, 4); Point point3 = new Point(4, 4); Point point4 = new Point(4, 100); Point point5 = new Point(50, 4); Point point6 = new Point(50, 100); Point point7 = new Point(4, 100); Point point8 = new Point(27, 120); Point point9 = new Point(50, 100); Point point10 = new Point(27, 120); Point[] curvePoints = new Point[] { point1, point2, point3, point4, point5, point6, point7, point8, point9, point10, }; formGraphics.FillPolygon(Brush, curvePoints); myPen.Dispose(); formGraphics.Dispose(); } Any idea?

jdunlap: Can you show me the code for a raised / sunken rectangle?

I need something like this: System.Drawing.Graphics formGraphics = null; System.Drawing.Pen myPen; formGraphics = pictureBox1.CreateGraphics(); myPen = new System.Drawing.Pen(System.Drawing.Color.Black,1); formGraphics.DrawLine(myPen, 5, 5, 105, 5); formGraphics.DrawLine(myPen, 15, 35, 95, 35); formGraphics.DrawLine(myPen, 5, 5, 15, 35); formGraphics.DrawLine(myPen, 105, 5, 95, 35); SolidBrush darkGrayBrush = new SolidBrush(Color.Gray); Point point1 = new Point(5, 5); Point point2 = new Point(105, 5); Point point3 = new Point(15, 35); Point point4 = new Point(95, 35); Point point5 = new Point(5, 5); Point point6 = new Point(15, 35); Point point7 = new Point(105, 5); Point point8 = new Point(95, 35); Point[] curvePoints = new Point[] { point1, point2, point3, point4, point5, point6, point7, point8 }; formGraphics.FillPolygon(darkGrayBrush, curvePoints); but just raised, lower and clickable. How?

Can someone show me how to draw a raised rectangle on a form using GDI+ ? When the user click the rectangle, then it must be lower. KeyDown = lower; KeyUp = raised; Thanks
