Jun 3, 2011I'm wanting to search a RTB for all X coordinate values and convert them to SI mm units.
I have two issues: 1. My code is stopping after the first instance of match.success, I'm guessing i'm using nextmatch incorrectly? I have also tried matchcollections with no success.
2. I fear once we get it progressing to the next X value, any multiple X values with the same dimension will be replaced with my replace command, causing the new value to be converted again.
Dim MatchObj As Match = Regex.Match(RichTextBox1.Text, "[Xx](?<X>(d*.{1,1}d{1,4}))(s)*")

Find Total Overlap Percent Of Multiple Rectangles ?
Jun 19, 2012I've got a list of System.Drawing.RectangleF objects that all overlap the same RectangleF object.In my picture below, the 3 overlapping rectangles would be the pink, yellow, and red rectangles.My main rectangle in question is the light blue rectangle.
Second Image: I know that with RectangleF objects I can use the Intersect() method that will return me another RectangleF object representing the overlap. But as far as I can tell, this only really works when comparing two rectangles.
My question is: How could I determine the TOTAL area/percentage (i.e. the combined total overlap of the red, yellow, and pink rectangles when compared to the light blue rectangle - but it would need to be smart enough to not count the area in which the red and yellow overlaps twice, and same for the pink and yellow)?
NOTE: The green lines represent the area I'm looking for, just the total area of the blue rectangle that is not visible.
UPDATE: I've added a 2nd image to further demonstrate what I'm looking for. In the second image, the presence of the burgundy rectangle should have no affect on the total percent covered because that area is already covered by the yellow and green rectangles.
Math.min - Find Smallest Number Typed By User In Text Box 1
May 3, 2011I have two text boxes on my form. text box 1 allows a user to type in a number (decimal) and text box 2 will display the smallest number typed in so far. The idea is to find the smallest number typed in by the user in text box 1, by using the Math.min method to compare each number typed in by the user to a variable that contains the smallest number to the point. Then replace the variable value with the smaller of the two numbers. To make it work for the first number. I have to initialize the variable to 99999. (no if else statements should be used).

Use Regex To Find A Dynamic Text?
Nov 29, 2009I'm needing to use Regex to find a dynamic text. It will always be found between the same things. Now, I'm sure that made little sense, so let me clarify. I have a rich text box full of text. I am needing to use a Regex method to find a certain string of that text that is always different. This string will be located between the same two pieces of text every time.
For Example: If this is my string: id ="user_name" ><img style ="display: block;" usr ="resentful" I need to find the text in between id ="user_name" ><img style ="display: block;" usr =" and ".

Concatenating A Variable With A Regex Group Match In Regex.replace?
Apr 5, 2012I am having an issue where I am using regex.Replace to replace part of a string. The basic idea is that I want to capture the beginning of the string then replace the end of the string with a value from code. For an example pretend I have a string that says "Test Number " followed by number and I want to increment that number. I capture the "Test Number " but when I try to concatenate that capture with the new number it treats the capture ($1) as a literal and replaces the entire string with $1[new number].
[code]...
This will output "We are on Test Number 2", as expected. how I can use a variable in the replacement string portion of the Regex.Replace when including a captured group?
