I am graphing using Visual Basic graphics and it works. I would like to know how to draw a DASHED line instead of a solid line. Could someone help me with this?gphFormGraphics.DrawLine(Pens.Green, pt2, pt1)

I see that the Line method is replaced with DrawLine, however; it seems like DrawLine must treated as an object as follows:
Private Sub Form1_Paint(ByVal sender As Object, ByVal e _
As System.Windows.Forms.PaintEventArgs) Handles MyBase.Paint
Draw a solid black line 25 pixels from the top of the form.[code].....
When I attempt to use this code (call it), I must somehow bring about an event, but I haven't found how to do that.How do I "call" this sub?
How to find the correct DashOffset and DashPattern to fill in the gaps with another color within a dashed line if the 1st DashPattern has an array of mixed values?
If the 1st array for a DashPattern is like this though?
myPen.DashPattern = New Single() {20, 15, 30, 45}
I'm trying to draw a solid line if VB.NET the way I can in VB.What I WANT to do is set the pentype to solidcolor, but it says pentype is read only and you have to instantiate the brush as the pen type that you want, SO ... I do this:
Public myBrush As New SolidBrush(Color.Red)Public p1 As New Pen(myBrush, 5)
And what I get when I draw a line is a pen type that is hashed. It's a bit weird, too. The line I'm drawing is between captures of the mouse position and if I move the mouse really fast, I get an almost solid line, but if I move the mouse slowly, I get a hashed line.
I have a picture in my picturebox. In that picture, I need to draw a straight line between two points and calculate the length of that line (probably in pixels). Is there any suggestion how to do it?
View 2 RepliesI am using word 2010 VBA to clean up a "dot matrix" looking report. One thing I want to do is replace a row of dashes with a solid line. I think the code would look something like this:
count strings = "-------------------"
for each strin (i)
select string
delecte selection
move up
insert solid line
next (i)
Or if it can be done as a find and replace all that would be even better, but I cannot find how to replace a row of dashes (text) with a line object.
This is simple program, draws a rectangle, marks the x & y axis, & plots a dashed line grid. However, the grid sub has to be called twice - only then will the grid line be visible. Why does this happen?
CODE:
I need to draw dashed lines. I use this code:
Dim MyPen As Pen = New Pen(Color.Black, MyWidth) With {.DashStyle = Drawing2D.DashStyle.Dash}
MyGraphics.DrawLines(MyPen , MyDots.ToArray)
But since the distance between successive lines it too short, the dashes start each one too near to the last. It causes a continuous black line

View 2 RepliesI need to draw a line on a series of pictures: I have decompiled a movie file to 1200 pictures. I also have 1200 samples of vector data (coordinates of the line: beginning point, ending point , size of vector (length) and direction (angle)... anything). With these data I want for each corresponding picture to draw a line corresponding to this vector data for instance: picture 550 needs to get a line drawn from point (5,95) ... these are (x,y) coordinates. in direction of 5 degrees from a vertical line and length 55. Visual Basic do that? I understand there will be some work in locating the origin of the x,y coordinate system and telling the program what 'size 1' means...

I want to move cursor with visual basic and it seems I found way how to do that. It is possible even click with Visual Basic whereever on screen. But I cannot check out where on the screen the click was done and so I want to draw two short crossing lines on that point as marker where Visual Basic clicked on screen. If it is possible to move cursor to that position and show it then it is as good as drawing marker.

View 1 RepliesI have a borderless form that I'm "docking" onto the top edge of my screen. Inside of the form, I'm placing a single toolstrip control, which docks across the entire form -> (picture the taskbar to get an idea of what I'm talking about).Because the borderless form has no edge to it, I wanted to draw a black line along the bottom edg` of the form to differentiate the form from the windows or desktop behind it.
The problem that I'm facing is that`the toolstrip will not move "behind" the line when it's docked, no matter how I order the control layers.
I've tried programatically sending the control to back to no avail either.
Any ideas on how to get the line to show above the docked toolstrip?
