View 6 RepliesDefine A 3 Dimensions Matrix With Different Data Types?
Dec 8, 2011I define 3 arrays: ID(n), Hour(n), Showed(n). If Hour(i) = actual time, I get the data pointed by ID(i), if not Showed(i).
BUT... I can add new hours or modify some existent, but I need to have the Hour array sorted. If I sort this array, the ID and Showed will point to different data.
So I though some different solutions:
1 - To make a string array with all inside (a 7 characters ID, a 5 characters Hour and 1 char for showed (T or F)). It could work, but, how can I sort the middle part of the array (Hour)? So, this don't work.
2 - A 3 dimensions "multitype" matrix (1 dimension of type Integer, the second of type Date and the third of type Boolean). I have no idea about how this can be done.
3 - A 3 dimensions string matrix, some like the "all inside" array: ID converted to a fixed size string, hour converted to a 5 chars string (hh:mm) and Showed converted to T or F. And sort the second dimension.
4 - Sell my copy of Visual Studio and drive a taxi cab

C# - Bug In The Matrix.RotateAt Method For Certain Angles?
May 24, 2010Here's the code i'm using to rotate:
Dim m As New System.Drawing.Drawing2D.Matrix
Dim size = image.Size
m.RotateAt(degreeAngle, New PointF(CSng(size.Width / 2), CSng(size.Height / 2)))
Dim temp As New Bitmap(600, 600, Imaging.PixelFormat.Format32bppPArgb)
Dim g As Graphics = Graphics.FromImage(temp)
g.Transform = m
g.DrawImage(image, 0, 0)
(1) Disposals removed for brevity.
(2) I test the code with a 200 x 200 rectangle.
(3) Size 600,600 it just an arbitrary large value that I know will fit the right and bottom sides of the rotated image for testing purposes.
(4) I know, with this code, the top and left edges will be clipped because I'm not transforming the orgin after the rotate.
The problem only occurs at certain angles:
(1) At 90, the right hand edge disappears completely.
(2) At 180, the right and bottom edges are there, but very faded.
(3) At 270, the bottom edge disappears completely.
Is this a known bug?If I manually rotate the corners an draw the image by specifying an output rectangle, I don't get the same problem - though it is slightly slower than using RotateAt.

Mar 29, 2011Question: I have data that I retrieve from a database, which looks like this: Now I need to transform it to the below format, in order to be able to draw a piechart. In ReportingService, there is the Matrix control to achieve this, but what can I use to achieve the same in ordinary C#, in order to render it to a PieChart image ?

Excel VBA Moving Matrix In Fix Range?
Feb 16, 2012My objective is to select specific positions in a moving matrix of a fix range with VBA for Excel 2003. The fix range is about 5 or so columns wide and has a few thousand rows. I select a matrix of 5 to 7 rows and same number of columns. I choose a specific position number in this matrix, write that number in another sheet and move on the next matrix just below where I do the same, and this until the last line of the range.
I've tried to write a loop function but this seems to take a lot of execution time.
