View 2 RepliesI'm trying to extract a piece of text from within the string, defining both a starting point and an ending point. For instance, say I want to search for the text found between "That is a " and " car" in the string "That is a red car", so it would return "red".I know you can use .SelectionStart and SelectionLength, but the length of the word can change, so the selection length can vary. What I want is to establish a specific starting point and a specific ending point from which to extract the text from the string.

I'm trying to calculate the direction between two points on a two-dimensional grid. Actually I want to determine if that vector is within a range of two values. Suppose the grid's origin is 0,0 at the upper left corner, and 0 degrees represents north. I have a point A on that grid. I want to know if a line from point A to point B on the grid is within a range of directions between 111.8 degrees (a little south of east) and 158.2 (a little east of south). Those are approximations; the 111.8 is 90 degrees plus the arctangent of 2/5, and 158.2 is 180 minus that value. I worked out a series of calculations worthy of a medieval astronomer, but I suspect there is a simpler way. I'm going to have to do this for a variety of other vectors, and I'd like to generalize

View 1 RepliesI need to move an ellipse from a known point on the screen to another known point on the screen.
I've tried using For.....Loops with less than desired results.
I can't remember everything I've tried, a lot of trial and error has been layed to waste. Lol
I've ended up with this code after putting together what I've tried, what I've learned elsewhere, and a couple of posts I've read on here.
All I want to do is move the ellipse from one point to the other along a straight line that forms the angle between the two points (X1,Y1) and (X2,Y2), make it grow from 2 pixels at it's start, to about 80 pixels by the time it reaches half way, then shrink from 80 pixels back down to 2 pixels by the time it reaches the point (X2,Y2).
Easier said than done.

View 1 RepliesWhat 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).
View 2 RepliesThere 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]
