Let's say I have a PictureBox with an image of a house, for example, and I want to know if the user clicked on the roof, the door, the window, or the walls.
Is there some way to, maybe, set up an If statement so that it checks what the coordinates of the mouse click was and compares it to a set of pre-determined graphed points to decide what object was clicked?[code]....
I am fairly new to vb.net and the form includes 3 picture boxes in red which you can click and change their color to green, also each picture box have three text box associated with it and they are by default color dark gray. I want the system to check whether the picture boxes are clicked and if yes set the associated text box colours to white.
Here is the code I wrote:
Public Class Screen
Inherits Windows.Forms.Form
Dim T(1, 2) As TextBox
Dim S(2) As PictureBox
Dim x, i, j As Integer
[Code] .....
Is there a way to check specific pixels in a picturebox to check the color? Basically what I have is a black square with some white dots, and I want to find the position's in the picture of the white dots.

I have a picturbox, which I redraw everytime you move the image inside of it... (g.Drawpath...) So in fact my picture is like 10000x10000, but my picturebox only 1080 x 540. So you only see a specific part of it. Now I'm trying to print ONLY the part I see.

View 3 RepliesI 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?
just wondering if its possible to fade out a picturebox slowly after it has been clicked?

View 2 RepliesI am trying to make a program which outputs an Invoice Number, which consists of the first 3 letters of a person's first name and the last 3 digits of their zip code. The user enter their first and last name, then enters their city, state, and zip such as:
Name: Billy Jones
City, State, Zip: Chicago, Illinois 42349
Therefore, the invoice would look like:
Invoice: Bil349
I can get the first 3 letters of the first name fine using the substring function, but I have been stumped on how to get past all of the text to get the last 3 digits of the zip code entered.
I have a loaded DatagridView which contains a row/column with an employee number in it. Outside of the DatagridView at the the top of my form I have a small PictureBox. My goal is for the user to select the employees row (not cell),pull the employee number from that row/column, and then use a LINQ query against another table to display the image stored in that table.
Determine the event needed in the DatagridView?How do I pull the employee number from the selected row?What considerations, if any would the LINQ query need to pull the picture from the table?
Basically, I want PictureBox1 to zoom in on a certain location of a form.
Like this
PictureBox zooms in on part of the form.
