I'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.
View 5 RepliesI hve been working with points a lot recently, and I have been wondering if there is a way to set a point without setting point.x and point.y separately. For example for (3, 5): Point1 = (3, 5) But that isn't right

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

I have a program that at one point will open word and export some info. That works perfect, however I have just noticed each day I have a number of winwords open (can only see them in task manager so they are hidden). It appears that everytime I start the program it opens a hidden winword session. It has nothing to do with the code I have on the form, it opens before any code I have written is executed.

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.
Here's what I have at the present.....

Dim H As Integer
Dim Num As Integer

I've been working on a Stored Procedure that checks the time, then retrieves records going back over the last full 24 hour period between 8am and the previous 8am. So, for instance, assume that it's currently 10am. The stored procedure looks at the current time, notes that it is past 8am, and sets the query to run backwards 24 hours, from 8am today to 8a yesterday. If it were, say, 7am, the query would be set to check from 8am yesterday to 8am the day before. This was actually relatively simple to do. The SP is meant to be used to retrieve records for a report tracking jobs completed in the given time span.
However, they've come back at me and asked me to change the stored procedure such that the hour the report ends at, and the span of time checked, is configurable from the front-end of the site. I have this working for TimeSpans greater or equal to 24 hours, but am having trouble with spans under that. Here's what I have so far for my logic in the Stored Procedure -
-- Retrieves data on jobs that completed/completed with errors during a given time span.
DECLARE @Hour NVARCHAR(2)
DECLARE @TimeFrame NVARCHAR(2)

I am thinking is to have a question, then between 2-4 answers, and depending on the answer a point value gets assigned to a variable, but then when that one question is answered you can click a button that moves to a next page type of thing with a new question on it. I think I could probably figure most of this out but when it comes to switching to a different question I am not sure how I would do that.

View 4 RepliesI decided it's time to migrate from VB6 to VB.NET and am currently translating my radio player but have run into several issues so I might be on this forum for the rest of the day... Anyway, in VB6 I used Inet to get the source of a PHP page that had the current song that was playing on the SHOUTcast stream. I can't seem to get Inet to work and figured I would just look for another method so I wouldn't need to pack msinet.ocx along with the finished product.
How can I get the source of the PHP page and store it in a variable or textbox/label.
