Replace The Text In A String "Sin()" With The Computed Value For Math.Sin()
Sep 21, 2009
I want to replace the text in a string "Sin()" with the computed value for Math.Sin() where is...anything. My problem: The string can have more than one right parenthesis. Also, since it is performing mathematical operations, it would have to know how to do the innermost ones first.
I'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)*") If MatchObj.Success Then
i need the max ,min, avarage, for the 24 lines that lines counted from the line that contain the max date so i get the code for the max date for in the txt file this code used for both if txt file sorted by Ascending or by Descending
What would be the easiest way to replace 1 instance of a text string instead of all of them using the replace function? I want to replace the first occurrence of the string only.
I am trying to take a block of text and scan it for specific text (name) and turn it into a URL, specifically:
Block of text:
Chairman Joe Smith has announced a new plan to decrease expenditures by outsourcing the planning of the new dining hall. Smith states the current project managers do not have excess time to commit to this new project and this will be less costly than hiring a new or contract project manager.
Now what I am trying to do is take any instances of Chairman Joe Smith, or Joe Smith, or Smith, or Chairman Smith and put that in a link to his profile/bio. Using any string methods that I know of (string replace, string builder, add text to before and after a matching string) I would run into the problem when scanning for Smith and then any of the other names.[code]...
I am selecting text using SelectText method in my string.I want to replace this text but only the selected area. When I use Replace method, it replaces all words in the string. (e.g This Computer is a good Computer. I only selected last Computer and want to say, This computer is a goods machine.)
I have the below code which searches through the file and replaces one string with another. However I would like to run this procedure on all files in a folder I was trying to use something like
Set f = fso.GetFolder(C:TestFiles)
For Each file In f.Files but I haven't figured out how to put it together.
Sub Main() Dim fso, inputFile, outputFile Dim str As String
I have to find a string in a huge text file ( ~ 50MB) and then replace it.Since it's quite huge I tend to open the file and then read line by line, and then replace the necessary line(s) (rather than "readall" the file of course).My question is how to replace the whole line?Let's say I found the line that should be replaced . I know I can create a copy file and copy all lines into there ... but I'd prefer to replace the line in the original file rather than creating a copy instance.
I would like to step through each *.txt file in a given directory, open it, find and replace all, perhaps a thousand, occurances of a given string (e.g. "00/00/00"), then close and save file, and step to next one in the directory to do the same find and replace. I've been looking at filestream classes and regular expressions but don't see a clear way to do this.
The file reads in parameters and two of the parameters used to be in Date Format YYYYMMDD but will now permanently be in format YYYY-MM-DD. This change, I believe, is stopping the import of the file from working. I would like to replace the new format YYYY-MM-DD back to YYYYMMDD in the code. If possible I'd also like to see some output so I know that the old format has been replaced with the new format. The code is below. I added the two rows with .replace code in green in expecting that to be enough but it is still not working.
Public Sub Main() Dim R1, O1, P1, C1, strDateFrom, strDateTo, strRunDate As String
I have thios code that will load a php file (text file) into a sting via streamreader then its supposed to find and replace a portion of the text and write the changes back out to the file via streamwriter. I put my code together and after running it look at the file and it's unchanged. After looking closer it appears the problem is the find & replace operation I am doing on the string. Here is my code:
well i am having a couple of issues with this particular homework problem and this is my first programming class so there is probably quite a few mistakes well the homework problem is to take three double values entered by a user and display the largest and smallest using math.max and math.min and display the smallest and largest so i thought i could use a listbox and take the values that went to the listbox and assign variables to each so i can try to use each variable in the math.max and min but im not making it to far and i actually might be way off
I have a bunch of object variables which are all initialised in their declarations such that:
Private _myObject As New ThisObject("SomeString")
where ThisObject is one of a number of object types, but all are initialised using a string.
I would like to use the Visual Studio Find/Replace dialog box to search for "As New" then replace everything from "As New" to the first set of speech marks with some text such that:
EDIT
My original example could be solved using other methods. This example is more representative of the actual problem:
Private _myObjectA As New ThisObjectA("SomeString") Private _myObjectLongName As New ThisObjectLongName("SomeString")
Given a string as a form of input (parsed from an input file) which represents a number and a mathematical operator (<, >, <=, >=, !, !=, and a few others), what is a really fastefficient way to chop off that operator, compare it to a list of valid operators, and then set an "operator" variable to a state (i.e., Enum) representing the identified operator, then return just the number (as a string)?I'm open to various ideas and implementations.I've tried several (about 6-7) myself, and find I'm not really satisfied with the speedThe fastest so far is a For Each loop that walks my list of "valid operators", and compares that operator's string representation against the chopped off bit from the numeric string. I determine the amount to chop off by the length of each valid operator in the valid list.
Here's a code example of the fastest implementation. Assume input like <378 and a valid ops list of <, >, !, or >=79 and a valid ops list of <=, >=: Friend Function FindMatchingOp(ByVal Haystack As String,
I'm making a part of my program that takes three inputs from the user and adds them then divides that number by three (the average of the three numbers). [code]...
how to go about populating some text boxes with results from calculations. To be more specific, I'm trying to do some trig to calculate various parts of a ci0rcle and will be populating any two of the text boxes then click on a button to get the missing values. I was thinking along the lines of a loop until all values have been calculated.
I 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).
Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String 2- Create sub-string 3- Erase a portion of a sting 4- Replace a word in the string 5- Count number of words and characters in the string without spaces. 6- Capitalize first character of each new sentence and convert the rest of the characters to lower case. 7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
Im trying to make a search bar that has a Go button now heres where it gets diffcuilt How do i make this search bar take the text in the the text bar and add it into a pre defined weblink and replace a bit of text with that word in the search bar so the user types into the text bar for example they type in NAME HERE so when you click go it taxt for instance [URL] now how could i make it so when you hit the GO button that it takes the text in the textbox and and replaced REPLACE TEXT in the pre defined address and put NAME HERE into the address and then load it up with a web browser and also how would i make it open up with the web browser that the person is useing (since lods of people use diffrent web browsers)
i am making a l337 speak generator..Lets say I input bob12321 (although i can input anything)I would like to make the program replace the "b" with either [code]How would i do that... I tried string.replace - but it says character A cannot be turned into long (on a seperate word)[code]
I have a non standard text file, ie its not delimted etc, its pretty much free flowing. What I want to do is to search for a specifc string eg. "xyz123" and then replace it with what a user types into a text box, lets call the text box and its contents "txtreplace".
I am trying to replicate a find and replace function essentially, but will need to tailor it later on down the line, but this will be a starting point.
I am using System.IO.FIle.ReadAllText() to get the contents of some template files that I created for email content. Then I want to do a Replace on certain tokens within the files so I can add dynamic content to the template.Here is the code I have, it seems to me like it should work just fine...
Dim confirmUrl As String = Request.ApplicationPath & "?v=" & reg.AuthKey Dim text As String = IO.File.ReadAllText( _ ConfigurationManager.AppSettings("sign_up_confirm_email_text").Replace("~", _

For some reason I cannot get the %%LINK%% and %%NAME%% Replace() calls to work properly. I checked to see if it was encoding-related, so I made each file UTF-8. And also used the forced encoding overload of ReadAllText(String, Encoding) and still no dice.
