I have a form that allows me to drag and drop pictures but I want it to check if the object is in the correct location
*curpic = the current picture that has been selected
If curpic.location.X > bx1.Location.X And curpic.location.Y > bx1.Location.Y Then
If curpic.location.X < bx1.Location.X + bx1.Width And curpic.location.Y < bx1.Location.Y +

I'm currently using the following code to take a screenshot of my desktop:
Dim r As Rectangle = Screen.PrimaryScreen.WorkingArea
Dim bmp As New Bitmap(r.Width, r.Height)
Dim g As Graphics = Graphics.FromImage(bmp)
[code].....
I'd like some direction in taking a screenshot of just a specific area. The area I need is where the rectangle encapsulates. If 've played around with it for a while tyring to figure out how to just take a screenshot of the rectangular area, but can't seem to figure it out.
This is a problem like the puzzle - "find minimum number of coins to completely cover a piece of paper".
The difference is:
in my case RADIUS of the coins is variable (but all coins should have same radius).
Real scenario:
1. I need to draw circular shapes on a rectangular image.
2. Number of circles (N) is CONSTANT/ User input
3. Size of image (S) is CONSTANT/ User input
4. The program should find the MINIMUM RADIUS (R) that is needed to draw N number of circles on an image of size S, so that, the image is completely hidden behind the circles.
This is NOT a puzzle/assignment that I'm trying to solve.This is part of a larger project that I'm working on.
I don't need any drawing code. I just need the code/algo to find the radius.
How would i check if an object is in a certain area inside a form?

0

For example lets say 0 = radiobutton1, inside a forms. What would be the best method to check if the radiobutton lies within this region?
How can I check if a ListView has items that are not in its visible area?
View 5 RepliesI want to create a dial which is basically a circle that I can drag around in a circular motion. Ive looked at using the code in an earlier post which allows you to drag items around a screen but I cant figure out how to confine the movement so it only allows the user to drag this circle around in a circular motion. Any coordinate altering I do just looks snappy.
View 6 RepliesI'm working on a Vb.net project. I have a form with a RichTextBox or a simple TextBox control. It contains hundreds of text lines, so the control has to be scrolled.
I want to send to a printer only the lines that are currently seen on the control window.
That is, I want to convert what I see into an Image and then draw that image thru e.Graphics.DrawImage.
As you can see, it could also be the case of a ListBox, a TreeView or any other scrollable control.
How can I grab that rectangle area and then convert it into an Image? The rest I already know how to do it.
I need a check that will see the location of the edge of the form. An example would be (for what I am trying to do) is, when a form is moved, the main form will get bigger depending which border and which way the second form is going.So basically I need some way to make Form1 get bigger if Form2 is near the left border or near the bottom border.
*I have a mini system for making it grow(LocationChanged) on the form I want it to work for.
*I also know about ".left" and ".top",
Is it possible to check a location for a file and if a file exists then create a new file (+1) in the file name? For example if there is no test file in the C:Temp folder then create a test.txt file and if there is one there then create C:Temp est1.txt and if there is a C:Temp est1.txt file then create C:Temp est2.txt and so on?
I was thinking
If Not IO.File.Exists("C:Temp est.txt") Then
IO.File.WriteAllLines("C:Temp est.txt" + 1, vbCrLf)
End If

View 3 RepliesTrying to set the viewable area to a smaller screen area and have it cycle through as the person moves using collision detection to move the backgroudn image. Here is the start but its off to a bad start so far.
Public Class Form1
Dim Mapx As Integer = 600
Dim Mapy As Integer = 2000
[code]....
Basically the forum size is set to 600x2000 but the client should only allow you to view 600x600. I want it to add +1 once you "collide with a invisable box I'll add and this will redraw the screen.
I designed a form and managed to fit graphics inside it. Picture box is 465 pixels high. Form1 is 500 pixels high. SnapShot of the screen verifies that the 500 pixel height is the overal height. It includes the upper Bar and lower frame. Is there an instruction to set the From's inner pixel size and not overal?

It should happen without setting its value using the SCROLL EVENT.
