VS 2010 - Image Magnification Centered On Clicked Point
Mar 5, 2012
I have a routine where I click on an image in picturebox1. When the user clicks I need picturebox 2 to show a section of the image in picturebox1 centered on the users click but zoomed in. I have the following function which is doing exactly what I want it to do (except properly zoom in.) I have been able to achieve something that appears to be a zoom but it no longer centers on the clicked point.
Public Function magnify(ByVal position As Point, ByVal main_pic As PictureBox)
vert2.Clear()
horz2.Clear()
Dim img As New Bitmap(pic_magnify.Width, pic_magnify.Height)
Dim gr As Graphics = Graphics.FromImage(img)
[Code] .....

I'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

I'm making a magnification program that has a form that follows the mouse around but I can't figure out how to do the magnification part. I thought of using a picture box and somehow get the image that would be behind of the form and just zooming in on it a bit.

I hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right

I am using the MouseClick event toc change the image of a picturebox when it is clicked:
Private Sub PictureBox7_MouseClick(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox7.MouseClick
PictureBox7.Image = Image.FromFile("C:Documents and SettingsjacobscDesktoplogogoclick.png")
End Sub
The problem i have is that this tool will be used on different users computers and not just my own and at the moment when it is used on another computer it gives an error that it can'f find the image.
This obvioulsy happens as it is looking for my desktop, how can i change so that the image can be saved within the tool and therefore will work on other computers?

frmMain.BackgroundImage = picWallpaper1.Image
End Sub
Private Sub PictureBox2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picWallpaper2.Click

I drew a filled circle using: pixFractal.CreateGraphics.FillEllipse(RedBrush, MyPoint.X, MyPoint.Y, 16, 16)
I expected the circle to be centered on MyPoint. Instead, it seemed to be drawn as though centered in a square whose upper left corner was at MyPoint.

I'm trying to center a label in my control, but it won't work! I can position it in the designer so that its in the center, but when I try to change the text in the label while its running it doesn't re-center. For example I have my label with the text 'Untitled' i then have a button which inserts text from a textbox on the same form. So 'Label1.Text = textbox1.text'. The problem is, when the new text is longer than the old text, the textbox is no longer centred and the text just goes over the edge of the page. How can I make the text in the label centered always?
