Get Chart Scale To Resize When Data Updated?
Feb 28, 2012What I have managed to do is currently display a chart with 3 bars on it linked to textboxes what have numerical values in them when the form is loaded. i.e TextBox1 has an initial value set in it's properties of 10, TextBox2 has a value of 20, TextBox3 has a value of 30.
When I run the program the graph displays these values correctly.
I have also got a button, Button1 which when pressed will plot the chart again, (so if I manually change the values in the TextBoxes after the form has loaded), it will display the new values via the bars.
The problem I have is that if if once the initial values have been plotted when the form loads, i.e. 10, 20 & 30, the Y axis of the chart has a maximum value of 35, so that all the initial values for the bars are shown. But if I change the values to say 15, 30, 80. and then press Button1 to update that bars to thier new values, the bars change but the one that show's 80 can not been seen fully as it goes off the chart, as the Y axis still only shows a maximum value of 35!
Does anyone know how to get the chart to resize to be able to display all the bar values within the chart each time the values are changed and the Button1 is pressed, whether it be reducing the graph for smaller values or enlarging the chart for higher values?
I am not 100% sure I am going about it in the correct way as I have not got any experience in using charts and am having to stuble about the net trying to find basic example code of how to setup and use a chart
My code so far is:
Imports System.Windows.Forms.DataVisualization.Charting
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load

View 2 RepliesResize An Imagelist/listview Image Without Repopulating The Image List?
May 17, 2009Does anyone know if it is possible to resize an imagelist/listview image without repopulating the image list? I am using scroll bar to change the image size from 25 point to 256 point. When I leave the scroll bar the imagelist repopulates from the files list. This can be very slow when working with high resolution pictures. I don't want to limit the image size to 2 sizes by using large and small imagelist.

Oct 6, 2011I would like for a user to upload an image to a file in my web application. However, before being saved I want to resize the image to a specified size. I have found code on the Internet to do what I want but I am having trouble adapting to meet my needs. Here is the part I am having trouble with:

Dim imageToBeResized As System.Drawing.Image = System.Drawing.Image.FromStream(FileUpload1.PostedFile.InputStream)
[Code]....
Rather than upload to a database I want to save the image to a folder in my web application. The problem I have encountered is that VB won't let me save a byte() to a folder. Not sure what I can safely change to adapt for my purposes. Why does it need to be changed to a byte() in the first place?

VS 2010 Resize An Image?
Aug 11, 2011I have a form where i load an image to a picturebox. I open a dialog to prompt the user to grab a file and once that is done i pull the image into a picturebox. Now i want to resize all incoming images but.... because of how it affects my ability to draw lines in the picturebox i am restricted to leaving the picturebox size mode set to normal. So i set out to write a resizing function.
The issue i am having is that eventhough i pass the function an image. I get the Height and with from the image object and it appears that i should be tripping some of my IF/Then statements ... neither Scl or Scl2 ever gets set which in turn keeps nw_height and nw_width from setting themselves properly.
All 4 of those variables stay 0 at all times and im not sure why.

Resize An Image While Taking In Account The Dpi?
May 7, 2010I have this fingerprint scanner I'm working with. The fingerprints taken are index/stored in our imaging system and the fingerprints are put on certain documents and printed.When I scan the image in and then load it into a bitmap object, the width and height are (w:480,h:640).Now if I open this file in any image viewer and print it from there the finger print is as big as a fingerprint should be.Now when working with it in code, it's huge. I have found some resize code online, but the resulting image is horrible.Is there anyway to resize an image while taking in account the dpi and such so the image is highest quality (same as print out?).

View 4 RepliesForms :: Resize A Picturebox To The Image's Size ?
Jun 1, 2010I'm currently in the process of making a dynamic signature generator, and I want to make the user be able to see what he would get... So I thought of putting a browse button and allowing them to load up a background image for their signature, but I also want the picturebox to resize according to that image's size. I need them to be the same size because of the image's X, Y are needed for the signature.
So I'm using this code for that:
LocalMousePosition = PictureBox1.PointToClient(Cursor.Position)
xy.Text = ("X=" & LocalMousePosition.X & "," & "Y= " & LocalMousePosition.Y)
It works fine, but it only gets the coordinates for the picturebox, not the actuall image, so I think if the picturebox is the same size as the picturebox it would get them just fine..
