RegEx - Displaying All Possible String From List In Textbox
Jun 7, 2011
I have a list of string. When user inputs chars in, the program would display all possible strings from the list in a textbox.
Dim fruit as new List(Of String) 'contains apple,orange,pear,banana
Dim rx as New Regex(fruit)
For example If user enters a,p,l,e,r , then the program would display apple and pear. It should match any entry for which all letters have been entered, regardless of order and regardless of additional letters.
I want it so every time I click an ITEM in the Listbox it displays ALL the data into the textbox. I know there's an easy way using table adapters and binding the listbox, but I'd prefer to do it this way for my project.
I currently have a list of words in a text file sorted in to alphabetical order and put into lower case, but I would like to be able to also display the line numbers on which these words are associated with.. but only one instance of.
For example,
"This is a random text file that I have just made up this second"
[Code].....
As you can see above, I would like to show that "this" for example appears on line 1 and 4. Hopefully tabbed so that it keeps a nice look to it.
I want the Function to accept List(Of String), Array & String and similarly return List(Of String), Array & String respectively. The Function simply adds a string (month) to the input collection. I just want to use it for string, array and list with needing to think of conversions.
I am trying to understand classes in VB 2010. I am a bit confused with displaying information from a list into a listbox.When I run the following code, the word collection appears in my list box. How do I drill down into 'hostnames' to display the info I want.
Firstly i apologise for another topic on a subject i have created already but this is a slightly different question and not related to LINQ at all despite the fact the code uses LINQ (the linq works fine and creates a List(Of Test) where each 'Test' contains a List(Of TestList) This data could be anything i guess and could come from an array or a database rather than xml literals.Ok, essentially i have a list which contains a list and i wish to display all the properties (List and list within this List) onto a DataRepeater Control. I have developed a testbed to get this working so i can implement it into my main application. Firstly I'll show the current code and how to construct the form and after that i will explain what i have tried and what i have had happen from these trials over the last week.
Public Class Form1 Private Sub Form1_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Using VB.NET, Is there a way to do this RegEx call in 1 step... instead of 2-3? I'm trying to find the word "bingo", or whatever is between the START and END words, but then also inside the inner FISH and CAKES words. My final results should be just "bingo".
Dim s1 As String = "START (random string) FISH bingo CAKES (random string) END"
I'm here again asking stupid questions. I don't have really get this but i ask again but i try explain all better. Here is a website link and i want catch string from here. Look page's source code and find first what starts <td> someword </td> I use this code for catch word from page. Visual Basic Express 2008
I'm trying to create a print function with a corresponding print preview. For some reason, any string I create with String.Format will NOT show up on the print preview! Use the code snippet below as an example:
Dim strTemp As String strTemp = String.Format("{0, 210} {1, 75} {2, 51} {3, 200} ", "NAME", "PRICE", "QUANTITY", "DESCRIPTION")
What I am trying to accomplish is this: I have a login page were a student logs in. After the login the student will be taken to a student user page. This page has 2 list boxes. The first is showing the exams that he has passed and the other shows the exams he has yet to complete or fail. I can not get any data to display in my list box. If I can figure the first one out I can do the second one easily but I can not get the first one to work. Here is my code that I have so far:
Private Sub Student_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load Label1.Text = "Welcome " & _passedText
the string ordering does not matter Z, X, or c can be any order in the string but the regex must fail if all three are not present. I can easily do Three different regex but was wonder can this be done with one expression?
I am using a ListView control to display Pictures along with description and caption. I used to save the full path of the image in the url field, so when I display them in the ListView I don't need to edit anything. Now I am using something like:
How can I edit my ListView to make it show the images?
I used to do the same to GridView when in GridViews RowDataBound event I manipulate the contents like:
Dim photo As New Image photo.ImageUrl = "~/photos/" + e.Row.Cells(TheCellNumber).Text e.Row.Cells(0).Controls.Clear() e.Row.Cells(0).Controls.Add(photo)
I can't seem to get the syntax right for this. I have a structure stored in a generic list and when it displays I get this "GenericList_T_.Form1+stuMotorInfo" in the messagebox. I've tried a few things and get roughly the same thing.
Here is the code:
Option Strict On Public Class Form1 Private Structure stuMotorInfo Public MotorId As String
So we are just starting to learn about list boxes in vb1. In this program the user enters up to 10 scores and after each input (decInputScore) the total score so far has to be calculates (decTotalScore) and then of course when all the scores are entered, at the bottom the final score it calculated. (decFinalScore) (decFinal). I'm not exactly sure what I'm doing wrong, I can't get it to calculate the correct total scores after each input, and I'm getting 0 as the final score. Here is a visual of what the form should look like: the black square is (btnEnterScore) a pop up message box comes up in which the user enters each value when clicked.[code]
I am trying to get VB.NET XML Comments to work with IntelliSense, and maybe it doesn't work the way I think it does.
[code]...
This should, when you are typing in a function, display the "Get or sets the Patient Code" then below that, it should display a list of bulleted items with "Validation:" as the header? Maybe I am doing it wrong, but it doesn't seem to be working correctly.
I would like to have a only part of a string... I have a string[URL] and i want only the part thats past the last / so i would actualy get only "file.part4.rar"I know that this can be done through Regex, But I have never used that, and I read the documentation on it, but I do not understand the part of...
Dim rx As New Regex("^-?d+(.d{2})?$")
What dose each of those characters do and how dose it effect the output...
I have a form displayed where a user can can select a 'function' from a list box. That 'function' has a corresponding ID number which I need to be able to take and use later in the code.The List of functions is preset (about 150+ them and the IDs are already assigned (so I can't just use the index).So if the user selects "Function A", I need the code to set a variable to, for example "42" (or whatever that Funtion's ID is).
I was going to do this using listbox.item and listbox.itemData, but I'm using VB.Net in VS2008 and I understand that function is no longer present (to add ItemData at design time).Here's where it gets complicated. When the form loads it looks at the variable containing the FunctionID and if there is one present, I want it to populate the co-ordinating FunctionName. I can do that if I know the index number, but I don't know how to look at the FunctionID and return it's index (all FunctionIDs are unique).
A) store the info, either in the Listbox using ItemData, in an array (but I'd prefer to do it at design time), or some other way you might suggest.
B) cross-reference the ID and display the name in the listbox when the form loads.
I need the code to filter the data entered in a textbox. Although it accepts all the characters during runtime, the code should remove all the strings and alpha numeric characters except the numbers (which would be my output). I tried the following code but guess it won't do:
a = Textbox1.text Dim value As Decimal = CDec(Regex.Replace(a, "[D]", ""))
I'm looking for regex to verify a correct domain has been entered into a textbox, it must have http:// conditional www. also must verfiy it has a TLD but must except TLD in this format to: .com.au, co.uk etc etc
Example of the regex i would like to outcome is [URL] or [URL] no trailing text like index.php
