User Muse Click On Drawn Line?
Oct 8, 2011
I have drawn (3) lines on a panel, each a diff color. I want user to muse click on a given line to bring up a label that will explane what the line is telling the user. There s/b no bit maps involved. I am using graphics to draw the panels and lines.
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
End Sub
[code]....
My code above will draw the line but i can not see how to use path to get a "hit" on mouse move for the line?I use private routines to draw many panels and assign pens to colors and panels. I must be able to connect panel and line ID to pen name to know the nature of the line to label it! I can see that path must be used; but how?

I am using this code to draw a line on a form using textboxes as the x and y coordinates. I then click the button with the code below that will draw the line.
Before the new line is drawn, I would like to have previous lines deleted first.
How can I delete these lines?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim canvas As New ShapeContainer

I want to draw lines (paths) for AI to follow. I need to know the X,Y coordinates of each pixel in the line.Lines drawn straight vertical (0 or 180 Degs), diagonal (45 or 225 Degs), or horizontal (90 or 270 Degs) are easy to map.I need to know how to map straight lines that are not one of the those three. Like 1 degree to 44 degrees, 46 degrees to 89 degrees, and so on...

I'm creating a type of drawing program. The user can draw a line, much like in word or paint, etc. But once the line is drawn (to a picturebox or bitmap in memory), I want the user to be able to click on the line and drag it around (translate it).
If I know the coordinates of the endpoints of the line, as well as the pen width it was drawn with, how can I tell if a certain coordinate (mouse location) is contained by the line?
My first thought was to take a mathematical approach, like get an equation for a line, and check to see if the coordinate belonged to it. But for a higher pen width, the line is thicker, and thus contains more points.
How can I tell what coordinates are part of the line? Is there some sort of intersect function in the gdi that takes a line?

Currently I have not found a way to generate an event when a user clicks on a line that is drawn in my workspace area. The line that is drawn is created by calling the function e.Graphics.Drawline(Connector,X1,Y1,X2,Y2), where Connector is a System.Drawing.Pen object and X1,Y1,X2,Y2 are integer coordinates of the two points to draw the line between. I have not found any events such as Click that are associated with the line that I can use. Do I need to create a custom event for these lines if so how do I go about this?

I need to draw several line-graphics on a form, then select and drag individual graphics to new locations. Is it possible for example to give each graphic path an identity when drawn, then select any one (via mousedown, whatever) and link it to the dragged mouse co-ordinates until released? MS Visio has exactly this ability - can it be done in .NET?

I want to write a vb program to allow user to draw rectangle. User can click on a point as starting position and drag on the screen. A rectangle is drawn with the current mouse position and the starting position. The user then release the mouse as end position. When the rectangle is drawn, user can resize the rectangle by drag the border of the rectangle.

I have my control here, and when the control isn't drawing selected, it has a random notch in the border(as illustrated in the attached photo). It uses a graphics path which is generally used all around so nothing changes there. Other than the fact the control is marked "selected"(which only effects the colors). Here's the code that generates my graphics path...

I have a vb.net application that uses Flash movies (AxShockwaveFlashObjects.AxShockwaveFlash). I have buttons in the flash movie. When they first start using the application, they can single click on the buttons in the flash movie and button responds accordingly. But after a while (and I haven't been able to pin-point an exact thing that changes it or my issue would be solved), the user has to double-click on the button in the flash movie for them to work.

I have a multiline label that im trying to add a line everytime I click the button. Its basically adding a new CD track name, CD minutes, and CD seconds to each new line for everytime the user inputs the given information:
1 Track_Name1 3 min. 13 sec.
2 Track_Name2 2 min. 34 sec.
3 Track_Name3 3 min. 01 sec.
.
.
.
But it keeps adding the "new" line in the position of the old one, so its only displaying on 1 line. I tried using a vbCrLf, but I might have it in the wrong spot?
heres what I got...
Private Sub btnAddCut_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnAddCut.Click
cutCounter += 1
[Code]...
The cutCounter is obviously the track number, and it clears the current info for the new information.

Is there any box type in vb.net that is multi lined, however stays as a single line and when you click on it , it will open up into a multi lined box (because I want 10 of them in a small area , in single lines will be perfect but needs to have lots of information stored in each one) and then when the user clicks out of the box / into the next one, it returns to its single lined state?

I'm trying to make a tool that supposed to do the following.
When I type i.e. the number 12345678 in TextBox1 and click on Button1. The number should go to RichTextBox1 on a new line with the text:
There Are 12345678 Bannana
Now, when I fill in at TextBox1 12345679 and click on Button1, a new line should be added to RichtextBox1, making it:
There Are 12345678 Bannana
There Are 12345679 Bannana
And so on...
What ever I try I cant get this to work,

I want to make an application in vb.net which will allow user to use mouse in a different way. i.e Dwell Clicking. Suppose user moves mouse pointer at particular location and if the user doesn't move the mouse pointer from that location for 2 seconds then single click will be initiated. How should I start? All I know is I will need a form, 2 buttons i.e for selecting single click and double click, and a timer!
