how to remove text. For example, I am trying to get the username of the logged on user (e.g. Bryn)into a variable. I did this with variable = My.User.Name
However this also brought the domain with it (e.g. aaabbbcccBryn).
Is there anyway of getting rid of the domain? The App will be used on many domains, so removing the first, say, 9 characters won't be any good.
I have a text file as follows:for example:
apple:1 southafrica:34
5.00
orange:2 southafrica:23
[code].....
I have the first part done, ... I can delete all the text before spacific text, ... now I need to delete all text after a spacific point in a string of text.
I'm making a better, and more simpler BandWidth Monitor, and I'm extracting the Bytes Recieved, ... but just the value, and leaving out all the rest of the text.
here ya go, check it out.

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 am able to draw points on a picture box. Add Labels to the points i draw. And delete the Labels at runtime.
It is the last part im having an issue with. Apparrently when i press the button to delete all the labels it does that because i can then start creating the labels again in the picture box starting at 0 again. But it leaves all the old labels visible on the screen. I assume i need to delete the Points to but this is beyond my current knowledge set.[code]...
I 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

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.

First, the overall objective is to find the best point within a multipoint filled 'star', at which to start drawing text. That is, depending upon the size of the star and the number of points, there is a larger or smaller area within the points that is filled with colour. So a 5 point star has a relatively small area that is filled, in which to draw text. A 40 point star of the same radius has a much larger area filled. If I can determine the size of this area as a rectangle, then I can measure the string and draw within it using the best fit font and starting position. The code below is an attempt to answer the question but I am stuck trying to find the text area rectangle within the filled portion of the star. Some of the code exists purely to explore the means to determine how to identify this rectangle (and is probably the totally wrong direction).
The second part of the problem is in exploring the options, I tried to draw a vector to different points on the circumference of the star. This is the code highlighted. The lines drawn do not seem to be the correct length nor the correct angle but I cannot see why.[code]...

I was wondering if it is possible to point to a textbox created in the form designer via a string variable. Basically, I'm creating a golf management system with a feature allowing a user to define their own course. Each hole has a corresponding textbox into which a user can input the hole's par and then the system should total up the first 9 pars, the last 9 pars and then all 18 pars; displayed in 3 different textboxes.
The input textboxes have been named txtP1, txtP2, ..., txtP18, so I was wondering if I could simply concatenate a loop control variable onto a constant of "txtP" to point to each input box.
This is what I have at the moment, but it's throwing up errors saying that .text is not a member of string.
Sub UpdatePar()
Dim inpar, outpar, totalpar As Integer
Dim pointer As String

how to add multiple text to a point pair list in Zedgraph. Add text to one point pair can be done like this:
Dim myPane As GraphPane = zg1.GraphPane
Dim TextObj As New ZedGraph.TextObj("High", 10, 10, CoordType.AxisXYScale, AlignH.Center, AlignV.Center)

Theres a problem with the code above when the graph scrolls the text is following as it should, but it's also visible in the pane background.
I want to add text whereever the blinking vertical line is in the textbox.

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
