C# - Transform A Datatable To A ReportingService-like Matrix?
Mar 29, 2011
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 can't seem to find a clear answer as to how to import the proper namespace for ReportingService [URL]. I tried to follow the instruction here [URL] but there is no Add Web Service option showing when I create a console application. There is a service account. Should I just use that instead?

What I am looking to do sounds really simple, but no where on the Internet so far have I found a way to do this in DotNet nor found a 3rd party component that does this either (without spending thousands on completely unnecessary features).Here goes: I have a jpeg of a floor tile (actual photo) that I create a checkerboard pattern with.In dotnet, it is easy to rotate and stitch photos together and save the final image as a jpeg.Next, I want to take that final picture and make it appear as if the "tiles" are laying on a floor for a generic "room scene". Basically adding a 3D perspective to make it appear as if it is actually in the room scene.Heres a website that is doing something similar with carpeting, however I need to do this in a WinForms application:Flor Website Basically, I need to create a 3D perspective of a jpeg, then save it as a new jpeg (then I can put an overlay of the generic room scene).

There is a bug in my code somewhere. It has a form with 5 input fields and 5 output fields. The algorithm is supposed to do a forward DFT and then immediately do a reverse DFT on the same data - so the output values should be the same. However it returns garbage! as I cannot see where the bug is.

I am grabbing some XML from an API and I want to tranform it before I put it into my dataset. I can't quite piece it together. I am trying to work from the examples in the documentation, but all I find are examples with reading and writing to the filesystem and I am not interested in storing things in the filesystem for this.
I am trying to piece together (1) xmlReader.create(URL) -> (2) xslcompiledtransform(xmlreader,xmlwriter) -> (3) get xmlwriter it into an xmlreader -> (4)dataset.readxml(xmlreader).
I can't figure how to do (2) and (3). How do I initialize the xmlwriter properly and feed it to an xmlreader?

After several hours of browsing google, wanted to check with one of you experts. I have made a winform application to read data from PABX (telecom) device. My application is listening to a particular port and once data received it passes to the data_hander. Application is working fine. But I�m facing a issue in received data string. From PABX system, it sends start and stop bit within the text string. It sends chr(2) as start bit and chr(3) as stop bit. But when my application reads the incoming data stream as follows,
ReceivedData = System.Text.Encoding.ASCII.GetString(bytes, 0, bytes.Length).Trim(Microsoft.VisualBasic.ChrW(0))
It does not recognize the start and stop bit as it sends from PABX. It just replace chr(2) and chr(3) with space and shows rest of the string. The issue is, I just want to take the same string and forward to another application and it needs this start and stop bits as it is to read the string properly. Could somebody guide me how to read this characters from PABX system or at least include them to the received string within my application as send to the other application?

Using the FileHelpers library to do some great things in VB.NET. Parsing files with dynamic classes built from text file templates. One thing I can't find: A way to read in a single record and determine that it should result in the generation of two records.[code]Ideally in this next line I would like it to see certain conditions and be able to generate two records from a single source line. Dim PayRecords() As Object = engine. Transform Records(FromRecords)Alternately, if there is a way to implement the "ITransformable(Of ..." TransformTo() and have it return multiple records, I could put the logic in the dynamic class definition TransformTo() method.[code]

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.

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

I'm using XamlWriter, XML Transform (with XSLCompiledTransform), and XamlReader to create deep copies of a user control with multiple user controls and lots of inheritance.
I have it working and am using it in my Print and Print Preview logic. The problem is that it's SLOW and I need to speed it up. Currently when the user selects Print Preview it takes about three seconds for the view to display. I need to reduce this to less than one second!
