I'm trying to create a valid RegEx replacement pattern for correctly formatting specific .XML file names. Specifically, if a file name does not begin with a prefix, let's say, ACE_. If the XML file name and extension does not begin with ACE_, prepend the string ACE_ to the file name.For example, if my input source string is the following:
Widgets.xml
I would like to execute a single RegEx Replacement that would result in the string being:
ACE_Widgets.xml.
Conversely, if the string already begins with ACE_, I would like it to remain unchanged. Also,how can I include the pattern ".xml" to ensure that the string pattern for the file name and extension ends with ".xml" in the same matching pattern for the RegEx Replacement pattern? As for the match, I have some luck with the following:
^ACE_{1}[dD]+
Which indicates there is a match for the pattern if the input string is ACE_Widgets.xml and no match if the string is Widgets.xml The RegEx pattern would suffice, but if you need to know the language in which I'd like to use the replacement pattern is in .NET 4.0 in either C# or VB.NET.
The following posting is close to what Im looking for, but with the inclusion of the *ix directory path prefix, and the use of preg_replace() in PHP, I'm having a bit of a struggle getting it to work with what I need to do:
Regular Expression: How to replace a string that does NOT start with something?
I'm writing some code that takes a report from the mainframe and converts it to a spreadsheet. They can't edit the code on the MF to give me a delimited file, so I'm stuck dealing with it as fixed width. It's working okay now, but I need to get it more stable before I release it for testing. My problem is that in any given line of data, say it could have three columns of numbers, each five chars wide at positions 10, 16, and 22. If on this one particular row, there's no data for the last two cols, it won't be padded with spaces; rather, the length of the string will be only 14. So, I can't just blindly have
This is a tricky situation. I want to extract a certain substring from the strings given below, using VB 6.0. I process each string (row) in a for loop one by one.
How will I select a substring with 2 criteria? I have a Richtextbox where I select a number after a : with this code; For Each line As String In Richtextbox1.Lines Dim equalsPos As Integer = line.IndexOf(":") + 1 txtFound.AppendText(line.Substring(equalsPos, line.Length - equalsPos)) Next This is working ok, but the whole line.length is appended for number2. The line ex. Some text:my number some text-my number2. I want my number appended to txtFound, and my number2 appended to txtFound2. With my code only number2 can be appended correct.
from the Help in VS 2008: Replace: Returns a string in which a specified substring has been replaced with another substring a specified number of times.
Expression Required. String expression containing substring to replace. Find Required. Substring being searched for. Replacement Required. Replacement substring. Start
Optional. Position within Expression where substring search is to begin. If omitted, 1 is assumed.Count Optional. Number of substring substitutions to perform. If omitted, the default value is 1, which means "make all possible substitutions."
Compare Optional. Numeric value indicating the kind of comparison to use when evaluating substrings. See Settings for values.
I want to be able to find both spaces using the indexof method. Here's my code so far. Basically the program will turn the string "Will Smith" to "Smith, Will" But I noticed when I type in a name with a middle initial or middle name "Will J Smith" I would get "J Smith, Will" And I want to be able to find that second space when its there and apply a code that would produce "Smith, Will J" When there is a second space. How would I go about doing so?
Is there a way to take an integer, say 10, and convert that to 10 spaces? What I've got is a text field that the users enters a number. I then need to convert that number into spaces and insert those spaces into a string of text. I've found several places to convert text to an integer but not the other way around.
lets say I had a string variable that contained "Hello World!", (or whatever the string contained) how would i remove the the right most spaces to make it say "Hello World" (im reading in items from a text file using substrings that has fixed positions with one line of the text containing several different items) or does it automatically eliminate the right most spaces???
I wan't a method with which to find a string within another string. It should return the position of the first occurrence of the substring. (In VB 2008 !)
i am retrieving a iMAGE Extension variable string. for example: test.case-function.two.jpg and want to return the end '.JPG' portion only. so i can add to another variable value. Note the .JPG substring could be other Extension types such as PJPEG ect
Is there something I am missing to pre-check a string for a certain number of instances of a substring? Example.
"I am a test string, I will be searching this string later. I will be checking for every instance of the letter "i" and return the number of instances of that letter."
If I wanted to return an int for how many times i occurs in that string.
Basically I want to retrieve all possible substring matches with n characters from a string, Here's my initial code but it only returns 2 matches.[code]...
I used a regular expression, which handles both numbers and letters in strings of arbitrary length, in one line of code. dim rtn as String = Regex.Replace(input, "..", "$& ")
I'd like to take numeric strings of arbitrary length and insert a space every 2 characters. So 1233456 becomes 12 33 45 6. Is there a way I can use format as string or IFormatProvider, like? That would put a limit on how long the string could be though, right? Since I'm casting to a long.
CLng((input)).ToString("## ") I'd like to take strings of arbitrary length and insert a space every 2 characters. 123dssas4rr should become 12 3d ss as 4r r
I have a string that I need to place to a file, but when I do place it to file, it gets cut off at the space, and the words after the space are placed to a new line. So I decided to place an underbar in place of all spaces, to avoid that problem. So how can I search the string for spaces and replace each with an underbar?
I've got some code that creates a list of AD groups that the user is a member of, with the intention of saying 'if user is a member of GroupX then allow admin access, if not allow basic access'.
I was using a StringCollection to store this list of Groups, and intended to use the Contains method to test for membership of my admin group, but the problem is that this method only compares the full string - but my AD groups values are formatted as cn=GroupX, etc....
I want to be easily able to determine if a particular substring (i.e. 'GroupX') appears in the list of groups. I could always iterate through the groups check each for a substring representing my AD group name, but I'm more interested in finding out if there is a 'better' way.
Clearly there are a number of repositories for the list of Groups, and it appears that Generics (List(Of String)) are more commonly preferred (which I may well implement anyway) but there is no in-built means of checking for a substring using this method either.
I've settled on using a List(Of), and I've borrowed from Dan's code to iterate through the list.
How do I make a regular expression to find a substring within a string that looks like: |sdrt446-7fdfs23| ? The number of characters and types change. So I need whatever in within the | |.
I need to create a code that searches an array of movie titles. When the user enters a specific string, the first movie title that contains that string is displayed. For example, entering "he" would display Sherlock Holmes as opposed to the Blind Side. I don't know how to create a code that reads a string that the user enters.[code]...
format a decimal value to a string with a single digit after the comma/dot and leading spaces for values less than 100?For example, a decimal value of 12.3456 should be output as " 12.3" with single leading space. 10.011 would be " 10.0". 123.123 is "123.1" I'm looking for a solution, that works with standard/custom string formatting, i.e.
decimal value = 12.345456; Console.Write("{0:magic}", value); // 'magic' would be a fancy pattern.
Environment.GetCommandLineArgs() splits string with spaces in it sometimes but not others, want to avoid this.

P.S. This was a VB6 command line app that I just converted to VB.net & the behaviour only occurs in the VB.net version. It's being called in many places at the moment, so don't really want to have to manually go through all calls & add double quotes around the whole argument.
I saw a built in function in VBscript a while back that converted a string with spaces to an array. However I can't remember the name and I looked it up in a few function listings and couldn't find it. Since almost all the functions that are in VBcript are in VB.NET I was wondering if anyone remembered the name of the function.
I'm implementing a feature which reads comma separated txt file from server(one line at a time). Format of file is fixed, There are 3 columns on each row. After reading the row from file I insert it in a database table. But first value of each row aoutomatically appends two blank spaces, even if there are no blank spaces at the begining of each row. I tried to use "TRIM/LTRIM/Replace" to remove blank spece from the first value of each row, but didn't succeed.
