How would I manually create a reparse point in a file and do all that stuff. I read up on how but it didn't make enough sence for me to comprehend on how would I visually show where to create the reparse point. I understood that it had to do with storing part of the file in memory for fast access and giving it a name to access it faster.[URL]..

View 3 RepliesI'm writing a tool that will have -at some point- to create a torrent. Now the tool is big and 'creating the torrent' is only a small part of it so I thought I can use a command-line utility that creates torrents but sadly it seems that there are no such tools available for windows ( found some for linux ). What are my options here? Should I just write a tool that creates torrents out of directories (I don't even know how a torrent file should be structured)? Or is there a way to control a GUI-Based application using my VB.NET program? ( Guess only C can do that, right? )
View 6 RepliesI have been left to maintain some vb.net applications - all of which utilize SQL server 2000 as the backend db. I need to change a report in one of the apps to include some newly added fields fromt eh database. I added the new fields to the specific table in the "testing" SQL server database which is on a completely different server. I am creating a new data source and have selected the database icon and then selected a connection string that clearly points to the test database on the test machine. I then selected the table containing the two new fields but for some strange reason, the two new fields I added are still not showing up in the list there! I have checked and double checked and it's as if it's still pointing to the live database on the live server where these fields do not even exist yet.
View 3 Repliesin order to create fancy custom end caps on the ends of a line, a structure like the following can be used:
Dim pts() As Point = {
New Point(-2, -2),
New Point(0, 0),

be used to create the same point array. I can see splitting these values into an integer array but how would these in turn be placed in a point array of whatever size is defined by the text values so they can be converted to end points of a line that is developed as values are changed in the text box.
I'm currently starting a new job in which I will be working on some coding in the future and need some advice on some good places to start so I can learn this correctly. Essentially we need to bring VB4 code over to the new VB.net language and I will be tasked with this. The project consists of a large battery of tests for psychiatric patients consisting of mostly multiple choice questions presented one at a time - since VB4 isn't very compatible, I think I will create a new battery from scratch while using the old code as a reference point.
I started creating the code this weekend for fun and am really enjoying it. However, a huge problem has been the abandonment of control arrays in the new language... by the time I got to creating my first questionnaire I'm stumped and can't follow the old code. Clearly I'm not ready to tackle such a large project with no experience and need to start from scratch; who would have thought .
The reason why I'm here is not to ask you to help me with my work. What I'm wondering is if any of you have any cool advice of great places to start learning the language (books, websites, etc). The amount of literature is very overwhelming so I thought I would ask some people with experience for tips. If any of you have stumbled across learning material with emphasis on coding that would be useful in the design of questionnaires or multiple choice exams, it would be particularly useful.
So far my starting place is Visual Basic 2010 Step by Step with Michael Halvorson, it seems good at a glance in the sense that it couples theory with practice but I'm already sure I'll need a little more.
I'm having a bit of a problem with a loop I made. So the setup is as following:We can create a routing somewhere in the world, from point A to B...and the program draws it on a worldmap.then I open a file with 300 zones in all over that country and he also draws these zones (it can go from polygons to circles. Some of these polygons are really small...when I click on a button I only want to see the zones which are connected to that routing...
So I use following script:
[code]...
this works fine, but not for the very small zones...I think when he uses GetRegionScans from those small intersections...the RectangleF is so small that he thinks it's empty.
I have a table with 2 rows named timeStamp and value. I know I can iterate through the rows and create points and add them to a list (new point(timeStamp,value), but is there a way to do it without iteration?

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.

Dim W As Integer
Dim H As Integer
Dim Num As Integer
