Finding The Subsequent Occurrences Of Character And Separate As Substring?
Feb 22, 2011
I am developing an application proj on it.. In that, I want to separate charaters of the string which is of following stream, 18 Feb 2011 06:05:24 0601 110218055515,3,26;9948;9948;9947;9951;9956;9954;99 61;9958;9965;9967;125672N0801272E;110218055550; In this I want to separate as, Mail recieved time = 18 Feb 2011 06:05:24 msg recieved time = 110218055515 msg sent time = 110218055550 Position = 125672N0801272E water level 1 = 9948 water level 2 = 9948 water level 3 = 9947 water level 4 = 9951 water level 5 = 9956 water level 6 = 9954 water level 7 = 9961 water level 8 = 9958 water level 9 = 9965 water level 10 = 9967 I am only aware of IndexOf and LastIndexOf methods, and these methods are used to find the index of first and last occurence character position, but I want to split the string in subsequent characters too..
I'm scanning through all characters in a textbox. Then the program counts how many of each character is in the textbox. Here's the code which adds all characters to a list:
For each c as char in TxtBox list.add(c) Next
Everything's working fine, except this will also add returns to the list, which I don't want. I thought I could write like this:
I generated 10 integers in the array(9). Then I separate the array into two parts by using substring. But I just can't run the code, it has no error but cannot run.
Public Class Form1 Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
I've got a string which could or could not contain the substring "/announce". I would like to replace this part of the string with "/scrape" if its found...so far nothing tricky. But heres the thing: I only want to replace it if the '/' in it is the last occurring in the string. Heres what I mean:
Heres a scenario where I want the replace to happen:
MyStringWithRandomText/announce?x=19 would become: MyStringWithRandomText/scrape?x=19
And heres another scenario where the '/' in announce is not the last '/' occuring in the string, so I dont want to replace it:
MyStringWithRandomText/announce/foo?x=19
I hope that made sense. Not sure if there is a way to handle this by only using RegEx
I'd like to be able to match a specific sequence of characters, starting with a particular substring and ending with a particular substring. My positive lookahead regex works if there is only one instance to match on a line, but not if there should be multiple matches on a line. I understand this is because (.+) captures up everything until the last positive lookahead expression is found. It'd be nice if it would capture everything until the first expression is found.
Here is my regex attempt:
@@FOO[(.*)(?=~~)~~(.*)(?=]@@)]@@
Sample input:
@@FOO[abc~~hi]@@ @@FOO[def~~hey]@@
Desired output: 2 matches, with 2 matching groups each (abc, hi) and (def, hey).
Actual output: 1 match with 2 groups (abc~~hi]@@ @@FOO[def, hey)
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))
I have a program where a user puts a string into a textbox, and then character one goes into Textbox1, char2 goes into TB2, char3 goes into TB3, etc. I have a For loop that gets all of my textboxes that are used for this, and I have my for loop that is supposed to go through my string character by character.
I am trying to write a VB function to strip unwanted characters from a string. It is for generating a 'clean' url from data that has been inputted into a CMS. Someone has copied and pasted from a Word document and so there appears to be an mdash or ndash in the product title. This results in ─ appearing instead of -
I have tried a Replace(text, Chr(196), Chr(45)) but it isn't working so it can't be 196. Is there a tool or something where I can copy this character and paste it into the tool and it will tell me what char code it is?
What do I use to find the position of a certain character in a string? Lets say I had a number 12345.6789 I want to know how far the decimal point is from the left? Of course the position of the decimal will change as the number will change.
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?
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.
I have made a program that minimizes a function of several variables. My question is why I keep getting diffrent results on subsequent runs? The inputs of all runs are same.
I am not sure how to make my program pause in the middle of execution, waiting for a certain period of time to pass BEFORE the next lines execute. I have already used System.Threading.Thread.Sleep(int) but this pauses the waits but still executes the subsequent code. If I were to:Private Sub Hello()System.Threading.Thread.Sleep(int)MessageBox.Show("Hello")End Sub* Time in milliseconds.This would NOT stop the execution of the MessageBox for int seconds, the program continues to run???How would I pause the code execution where I want, and for the time I want?
I have written some code in a form which is shown via ShowDialog from a different form. This code fills a DataGridView with data from two tables in a dataset, one through data binding, and one through more manual means. The latter part runs, or more accurately, fails to run in the same way if I call this form in the same way subsequently but without stopping debugging.
I have a listbox in a datagrid that is supposed to update upon selection change, and it does, but not on first try. only after it has posted back, after the first time it is clicked will it work as intended.Here is the front end portion of the datagrid with the listbox.
I created a telephone number form where the user enters the telephone number in a text box as (nnn) nnn-nnnn. The first 3 digits in parenthesis are the ISD code, the next three are the area code and the last four are the local number. I need to separate out these three fields of the phone number and display in three separate text boxes labeled appropriately. Now, suppose the user enters the phone number in a text box as a continuous string of 10 digits, where the first three represent the ISD code, the next three represent the area code and the last four represent the local number. I'm lost as how to change this string into the form (nnn) nnn-nnnn. This is what I have
I have a TabControl object on my form with many tabs created in code (TabPages) and my problem is that the same objects that are in the initial TabPage needs to be in the other TabPages created in code, I have this done in code when the user clicks the 'New Tab' menu option, however the same code is used for any new tabs created. The problem created here is that I have an event against one of the objects that appear in the other TabPages, but because the same code is used to create any new tab pages, the event will only work on the newest tab page, if that makes sense? By the way these objects that appear on the other TabPages are properties at the top so events can be handled against them in the respective subroutine.
I'll get straight to my problem - I'm currently coding in Visual Studio.I have a table (countries) with the columns ID | Name. The table is filled with around 28 records.I also have a form with 4 combo boxes (set up as 1,2,3 & 4) that I want the user to select. These combo boxes will display the names from the table countries. I then want to use the selected names in the combo boxes to Insert into their corresponding ID into another table. For example England would have the ID 1, USA the ID 2 etc.So, is it possible to have separate combo boxes that will give separate ID values but using the same table? At the moment I can't seem to find a solution.Eventually the form will have more than 4 combo boxes so I don't want to use separate bindingsources for each combo box.
I have a project that has several combo boxes on one form. The selection in a box can affect the possible choices in subsequent boxes. Right now I am using SelectedValueChange to fire the code that loads the choices in the later boxes. There are a number of possible events that I could use:SelectedIndexChangedLeaveLostFocusTextChangedI was wondering if someone could give me a rough idea what the differences are between these. Is there a 'best' evnet to use?Also, I find that most events work when the choice is made with a mouse click but if you click in the box and type in a value an event does not fire. How can I program for the case where the user enters a value by typing it in instead of choosing from the drop down list?
1) How do I use cookies obtained from login to do subsequent requests? e.g. Login to a forum, then use the cookie obtained from login to access User CP and change settings.
2) How do I parse HTML via HttpWebRequest? Does mshtml work with HttpWebRequest? If so, how do I work with it? I thought of downloading the source code of the page I'm requesting into a richtextbox and do my stuff from there, but it sounds kinda impractical to me since I have to use regex to get the innertext of stuff (or not?).
I am trying to dynamically resize labels and position each subsequent label a perdetermined distance from the end of the label that was just generated. My code looks like this:
