I have a matrix:
Module Procedimientos
Public Datos(200, 4) As String
Public Sub Inicio()[code]....
It is a Class made with the Add Windows Forms Menu.I have another Form where I added from the ToolBox the DataGridView Item.
Everything till now works like a charm, the problem comes when I try to load the matrix (previously posted) into the DataGrid. I search for the matrix via DataSource Button (from DataGrid's Properties) but I can't find it, it'll only show up the other forms. I don't know what I'm doing wrong.

how do i use pdfptable as a real table (A x B) instead of just (A x A)
declaring it this way gives me just one row:
Dim datatable As PdfPTable = New PdfPTable(4)
how can i declare it so that it has multiple rows and multiple columns?

I want to know if there is function to know whether the printer you are printing on is a dot matrix?
Our official receipt is printed in a dot matrix and must not be printed on any other kind of printer.

I've been looking into this problem for a few days now and i can't find exactly the code that i want.I want to run a procedure using an incrementing matrix. If the Matrix that was used is correct then the correct matrix is shown.
the process is get first iteration process if incorrect repeat with next iteration correct end the issue is with the iterations and breaking out of them the matrix length, depth and iteration step can vary.
this is best shown in an example
length = 5
high = 3
low = 0
step 1
the iterations should look like

Here'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.

Question: 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 ? Note that the number of buildings as well as the usage-types is variable and not known ahead of time.

I want to create a (3n*7) Matrix in python through Iteration, I did this in VB.Net and it worked but it gives me some challenge in Python as this a new language to me. n can be the number of Iterations to build up the matrix, i.e. ; if u iterated 3 times, the matrix will be a 9*7 matrix. Here is how I did it in VB.Net. :

My 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.

just hoping that someone may be able to point me to some information where I can create VBA objects in vb.net (I am using VS2008). For example, I would like to create a new object in VBA with the command (Dim x as Matrix) where 'Matrix' is an object with various properties and methods.

I 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

I'm asking this question here, in this forum, as I couldn't find MSDN Managed forum for Crystal Reports. And the previously asked questions are unanswered. I've developed an application using VB.NET and Crystal Reports in VS2008. The report generated gets printed correctly on modern laser or inkjet printers. However, the entire formatting gets affected when I print these reports on dot matrix printer. Apart from that. the print speed is very slow. I tried exporting the report to PDF, XLS, DOC and other formats - but no solution. There was Export to Text function, which is not working in Crystal Reports now.

I have a picturebox inside a panel with scroll bars.
I can zoom in or out the image in the picturebox by changing the PictureBox.Size, and the scrollbars update automatically.
How do I convert coordinates in pixel returned by the PictureBox.MouseMove event into image coordinates when the scrollbars value is not zero and the PictureBox.Size is not the original?
