View 4 RepliesDeclaring Jagged Or Rectangular Array
Sep 21, 2010I'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".

VS 2008 Create Rectangular Array From List?
May 25, 2011i 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.

Coordinate Of Mouse Move Not Same As Rectangular
Mar 31, 2011Private 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

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.

Algo / Code To Cover A Rectangular Area Using Circles?
Jun 13, 2012This 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.
Display Value From Array?
Jul 27, 2009[code]...
If I use the exact same thing but I say txtFirstName.Text = "found", Then "found" shows up in the text box when I click the button and the first line is true.
That tells me that there is a value in .strEmployeeNumber, and it is in the *same* array as .strFirstname, so there should be a value in .strFirstName as well. But for some reason, when I click the button and the first part is true, it overlays a string.empty and clears the box instead of the First Name.
