I am trying to incorporate in my vbdotnet application a form in which I would like to make a thumbnail from an image. So what I have is two picture boxes, one with the source image and the other with the destination image, I would like to crop the image from picture box 1 and display it on picture box 2, but the way I wan to crop it is not giving the coordinates of the selected area box but to simulate a selection area box in which the mouse can move the box and select the area of the picture to be cropped. This selection area box would give me the coordinates i need in order to proceed the cropping. The problem is I don't know how to create this selection area box. It is like doing the cropping on a graphic design software like Macromedia Fireworks, Adobe photoshop, even paint.

I'm just getting started, and it's as simple as that: I need guidance to draw a rectangle or place a dot or a point on Form1, in VB 2008 Express. I knew how in VB6 -- let's build on that.

faster way to flood fill an area of a bitmap? It basically acts just like the fill flood bucket in MS Paint. clsBitmapImage is a Bitmap variable.
Code:
Code:
Public Sub FloodFill(ByVal AtPoint As Point, ByVal newColor As Color)
Dim oldColor As Color = clsBitmapImage.GetPixel(AtPoint.X, AtPoint.Y)
If oldColor.ToArgb <> newColor.ToArgb Then

If I have a control, in this case a button, can I restrict the area it considers valid for text?
In the attached image, the left and right arrows are custom drawn in the paint even, I also have a scroll timer that scrolls the text if the length exceeds the buttons width as measured by Graphics.MeasureString.
I want to restrict the text from red line to red line so when the text scrolls it does not interfere with the arrow indicators, can the text area be overridden to some custom region?

When a button is focused by pressing Tab key, a rectangle appears on it. Even if the button's TabStop property is set to false, when the button is clicked with mouse the rectangle appears. Is it possible to
stop the rectangle from appearing?

I'm making a custom class that mocks the System.Drawing.Rectangle class because the Rectangle class doesn't have a name property. I need a name property because I am adding all of my rectangles to a collection and I need a little more info stored than just their locale and size. So I changed the _onPaint event but nothing is working out when I run the program?
Public Class Rectanglar : Inherits UserControl
Public BackgroundColor As Color = Color.Blue
Public Sub New(ByVal name As String, ByVal XY As Point, ByVal Widthy As Integer, ByVal Heighty As Integer)

How do I remove the area in a dropdown menu where the menu item icons are typically displayed?
I just need to remove the grey area in this particular dropdown, other dropdowns of menu items in the same menu bar need to retain this area because they do have icons.
Edit: This is WinForms.

I have an application that downloads a .jpg snapshot from an IP camera, writes it to the server hard drive, attaches it to an email and sends it out to my users. Pretty simple until one guy had to mount his camera upside down and that's how he received the image via email.
It gets a bit annoying after a while, so he asked me if I could rotate it 180 degrees before attaching it to the email. I have absolutely no idea - hence my post. The app is on a hosted ASP.Net v3.5 web server.

I am trying to draw an image from a MS Access database by use of e.Graphics.DrawImage(New Bitmap()). In my database Row 0 Item 1 holds the path to the image I want to draw.
My current code looks like this:
Code:
Private Sub pnlStart2_Paint(ByVal sender As Object, ByVal e As_ System.Windows.Forms.PaintEventArgs) Handles pnlStart2.Paint
e.Graphics.DrawImage(New Bitmap(ds.Tables("Track1").Rows(0).Item(1)), 3, 3)
End Sub
When I run my program I get the following message in my code: Illegal characters in path how I can draw the image from the database?

I am trying to verify that an image has been loaded into the picturebox1. I am loading the image from the web and need to verify it has arrived before I can save it to disk. If I save it to soon I will save nothing and that will crash the app. I have tried to use 'if PictureBox1.image = nothing then' ... 'End If', but that isn't a valid check. I can obviously not check picturebox1.image if it is empty or has an image.
So the question is, how do I verify that the file has finished loading?

I vagely understand how to edit an image using Graphics. I can rescale an image using scaletransform but I want to be able to use a dynamic scale i.e., given an image with (x,y) coordinates, I want x_new = x_old + y*Factor so that when the image is stretched one end is stretched more than another.

I would like to create a pixel viwer (i.e. zoom into a picture to view the image's pixel information - Similar to windows paint or Photoshop). I have created an image zooming code, but it enlarges the image and sadly, doesn't show the blocks of pixels I was hoping for.I have thought of several ideas, but each worse than the next. As an example, re-create the image, increasing each pixel's area based on the zoom-level. But I can tell already that this process would be slow and judging by photoshop (or paint) there is a quicker method.
