VS 2010 : Search For Text Within A String (Starting Point And Ending Point)?

Dec 31, 2010

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.

Delete Text Up To A Certain Point?

Feb 6, 2011

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.

Using String Variables To Point To Text Boxes?

Jun 12, 2011

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

Delete Last String In A Text File?

May 13, 2010

I am trying to delete the last line of a text file, then append new text to the end - The problem I have is that the code I have is set up to search for an Index, not a String, or the EOF line - I tried to modify it to search for the end string in the file, but that didn't work, either - Here's what I have:

'Delete last line

Create Point Array From Values In Text Box?

Jun 28, 2011

in 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),

[Code]....

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.

Identify Best Point To Start Drawing Text Within?

Mar 10, 2011

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]...
