Is it possible that after you find a string, backup until you find a specific character and copy it?For example, I am looking for "bread". The text is milk8andbread. Would it be possible to start at bread, back up until eight, and just copy "andbread"?
I'm looking to use a RegularExpress to find a specific pattern for character within a sentence.I'm look to find a any Word that start with '_', that contain only upper case character with number and with like

I am writing a hangman type game and I am displaying the word to the user in a label as all *'s, but I cannot figure out how to have just one of the *'s changed in the label to the correct letter when the user inputs the correct letter into the text box and clicks the check letter button.Everything else in the program works perfectly, except for this part.[code]When I use the .Replace it changes all of the *'s to the correct selected letter.
I am trying to find a specific file in a specific directory and then i need to get the full path of the file.Is this possible i cant find any help topics about a specific file.
so in a program I'm working on in VB.NET I'm trying to make it so I can take in a list of strings (each on a different line). For each line I want to take in the line, and break it up into three parts. The first part goes from the beginning of the string to the first colon in the string, the second part goes from the first colon to the at symbol, and the last part goes from the at symbol to the end of the string.
For example, I'd take in a line of the series of lines: hello:world@yay
I'd want to break it into three separate strings of "hello", "world", and "yay".
I'm trying to transfer only the numbers after the £ Character from Textbox1 into Textbox2. If textbox1 contains numbers before the £ character then it just transfers the first numbers before the £ character which is not required.[code]
I have a block of text in a text .txt file that looks like this: [code]I've tried reading every character and entering them into a 2D array (failed)I've tried splitting them into individual lines and entering them into a 1D array (Success, but very difficult to target individual characters from this, and will take a long time to set up as I only did this for 10 lines)
I'm trying to copy only the first 15 characters(Including spaces) of a string from TextBox1 to Textbox2If the Text in TextBox1 is:abc1234 jklmnopqrst/uvxyThen the Text in TextBox2 should read as:
How would you select the last part of a string starting at a specific character count. For example I would like to get all text after the 3rd comma. but I get an error saying "StartIndex cannot be less than zero."
Dim testString As String = "part, description, order, get this text, and this text" Dim result As String = "" result = testString.Substring(testString.IndexOf(",", 0, 3))
Let's say I have a textfile which contains paragraphs. Some of the paragraphs start with * or a > character. How do I index the words that start with these characters?
I am trying to develop a HANGMAN game and i need to implement a button where the user can click on it to "buy" letters. So, i designated 2 text boxes (one visible containing stars and another one not visible containing the word that should be guessed), and i wrote the following piece of code so that once the user presses the button any of the stars will turn to the correct letter. My question is, i found the index of "*" and removed it, and now i want to insert the corresponding char with this index (WordInLetters). How can i find what char is at index "index" in vb.net?
Private Sub picBuyLetters_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles picBuyLetters.Click Dim index As Integer = txtWordinStars.Text.IndexOf("*")
I have a string of text being sent through a serial port to a text box (Text1.Text). The string has some symbols in in which I am assuming are Hex values. The hex values are Hex(1), Hex(4), Hex(12), and Hex(17). What I need to do is find the position of these hex symbols in the string of text so that I can split or grab the data after the specific hex symbol. I am not able to use substring or indexof or instr ... or at least I am not using it correctly to find the appropriate symbol.I was thinking if I need to iterate through the string character by character and grab each symbol or text and get their value??? If it is one of the hex symbols, then get the index number (or position).
I am using a simple regular expression (in C#) to find a whole word within a block of text.
The word may appear at the beginning, end or in the middle of a the text or sentence with in the text.
The expression I have been using word has been working fine however if the word included a special character (that has been escaped) it no longer works. The boundary is essential so that we do not pick up words such as vb.net as a match for .net.[code]...
I'm trying to copy an array starting at a specific based on the number of variables I have. I have the program give me the number of variables. What I need is to copy the original array, UnsortedArray, start at the index of var + 1. I have tried the Array.Copy and Array.CopyTo, but I get the error that my new array, UnsortedNumArray, is used before it has a value.I know I've mostly overlooked something. Could you please point me in the right direction? [code]
I have a program that copies files listed in an excel file and adds two columns together to rename the file when it is copied. This all works perfect. What I am having difficulty with is when the files are copied and renamed - I can't get it to find files in subfolders and copy them also. I have a text file that is created letting me know what files were not copied and the subfolder files are always on there?
For Each foundFile As String In My.Computer.FileSystem.GetFiles("C:Documents and Settings oeDesktopMy Music2", _ FileIO.SearchOption.SearchAllSubDirectories, "*.mp3") My.Computer.FileSystem.CopyFile(foundFile, "C:Documents and Settings oeMy DocumentsMy Music" & foundFile) Next
Error message is on the third line: The given files path's format is not supported. I have tried all variations to this without any luck.
I want to copy files with a specific extension (for example .config or .exe). It should create a structure of nested directories, and then insert each file into a specified place in the directory hierarchy. Ideally I would just specify a parent directory for each file and a parent directory for each directory and it would build it.
I need any existing utility or batch file or power-shell script or C#/VB .Net code to perform this activity.
Does anyone knows how to export/extract/copy (or whatever is the right word) a file wich is added to the soulution, on the startup of a program, like somekind of installation?
