Take A Screenshot Of The Rectangular Area?
Jun 15, 2009
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.

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 +

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.

So I'm trying to take a screen capture of the windows form and display only a certain specified area of that screen capture in a picturebox on a different form. Kind of like this. First, take the screen capture of the form: Then get a specified area of that form through x,y coordinates or something and display it on a picturebox on a separate form.

Trying 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?

In a rectangular array which is correct or considered standard? dim array(row,column) as..or dim array(column,row) as. Not sure it actually matters outside of how it looks in your head.

Private Sub PictureBox1_MouseMove(ByVal sender As Object, ByVal e As System.Windows.Forms.MouseEventArgs) Handles PictureBox1.MouseMove
Label5.Text = "X:" & e.X
Label6.Text = "Y:" & e.Y
End Sub
Dim objectrect As Rectangle = rects(0)
Dim object_x As Integer = objectrect.X
Dim object_y As Integer = objectrect.Y
Label7.Text = object_x
Label8.Text = object_y
I discovered that these labels are not the same, the mouse move is more accurate. My mouse is currently pointing at the upper left corner of rectangular.

I'm working on a reporting section of code for an inventory app I'm making for my office.I call a text file, read every line into an array then populate information pages with what has been pulled from the text file.For reporting, I want to read every text file in the directory, reading each one into a multidimensional array.Thus I can call and report on each item, i.e.ItemArray(i,2) would be all systems with Windows 2008 EE..I have code that lists all files in the desired directory and counts each file, so I eventually get counts of how deep I need the first level of the jagged array to be. but not until after code execution. Basically how can I write each array of data to the jagged array.[code]But I get a null reference exception. "Use the new keyword to create an object instance".

i read data from a textfile into a one dimensional array (string()) and refer to that later on to build a new list with just the lines i want. using chartData as New List (of String) I can load the List collection just fine. Now, I want to send the output to a table so I can bind it to a datagrid. using Split and AddRange breaks the one dimensional data up into new rows but I want this sort of thing:
"Row0 Cell0"->"Row0 Cell1 "->"Row0 Cell3";<line break>
"Row1 Cell0""Row1 Cell1"Row1 Cell3;<line break>
Note I provided for characters that can be used in a split function (-> and vbTab), which works, but the split in the List gives me a one dimensional array.

The VBA Code is
ActiveSheet.Shapes.AddShape(msoShapeRectangle, 105.75, 54.75, 114, 65.25).Select
ActiveSheet.Shapes.AddShape(msoShapeOval, 441, 57, 117.75, 90.75).Select
For VB.Net, I tried looking the prefix for "msoShapeRectangle" or "msoShapeOval" in
Microsoft.Office.Core.MsoShapeType. But couldn't find it.

I guess thats what I need to do, Im trying to allow the user to right click on the top of my form, and my custom Context Menu Strip is displayed, not windows context menu strip. I guess somehow i would need to get the size and draw a rectangle on the non client area and see if the user has right clicked in that rectangle? if so how would I get the area of the non client area?

I have a bitmap displayed in a picturebox.The bitmap is a moderately complex image. It isn't a solid color, nor is it some repeating pattern,but it is a picture with a very narrow range of colors (all blue).I have a way to alter the whole image in a suitable fashion to indicate that it has been selected.What I would like to be able to do is alter a rectangular portion of the image in some way.Ideally,I would be merging in a semi transparent color such that a segment of the image would have a different appearance to it.
