For each character of this string I want a new character out of the string and then remove the character from the list of characters that still maybe used for other characters. It may not get the same character, you could basically just call this encryption, but it's not what I am making. I don't want to waste my time doing this one hour while VB can do this for me in <1 second.
the coding is to 'Get input string and put its character into List, and replace the character with other.'but having problem putting each character into List and also replacing it,[code]
I want to user to enter only numbers and characters in textbox i.e no special charaters.I don't want to use key press event of textbox.As i need same validation in gridview.
I am trying to filter a ListBox based on the presence of a string. Basically, if there is a ListItem that doesn't contain the string then I want to remove all ListItems that do contain the string. Here is what I have tried:
Dim Item As ListItem For Each Item In CtheList.Items If Item.Text.IndexOf("W:") = -1 Then
vb 'CHECK IF "sIntroSequence" IS AVAILABLE IN TEXT FILE. Dim checkthevalue As String = My.Computer.FileSystem.ReadAllText("c: est.txt") If checkthevalue.Contains("sIntroSequence") Then '"INTRO SEQUENCE" STRING IS AVAILABLE. 'CHECK
[code]....
I can't seem to get the checkbox checked according to presence of a particular string in a text file. It looks like it should work but it doesn't.
My form has a texbox where user enters an ID. IDmust be4 chracters in length andof the form: begins with either "E" or "e" and the next 3 chracters cannot be "all characters".
I'm having kind of a hard time about this, just would like to ask if anyone knows how to check if a string that is input by the user in a text of combo box is in the list of the combo box?
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've been working with the substring command and after coding up all the things I needed it to do, I saw a post on here where the "For Each" statement was used basically to do the same thing.Lets say we just want to take a string apart one character at a time and add each character to a label. Which would be more efficient?I made a cheap example to show ...
Code: ABinary = "0110 1100 0001 1011" For x = 0 To Len(ABinary) - 1
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 have a streamreader that is reading a file that has the possibility of having the contained information being separated by either a space, a semicolon or a comma, or even a page break.How can I check for all those things and then place them in a array?'I know this is the way to check for one character, how do I add on to this?
Sometimes when backing up an sql file using phpmyadmin (database stuff), for some reason it forgets to double up a single quote, resulting in an error when loading the sql file back into the database when required. A line in such an sql file looks like this;[code]As shown in the example, phpmyadmin did double up the quote in "you're" as it should, but it forgot to double up the one after "27", resulting in an error.As you can see it's like this (*value*, *'value'*, (and so on) but beforehand I can;
A) Never know how many values are in such a string B) Can't simply split the values by "," because the value itself can hold a comma aswel.
It would be easy if every value was like this; *'value'* because then I could split by " ', ' " but that's not the case, and I also never know what location the values not enclosed in single quotes are. I also can't simply double up all single quotes in the entire string because then it will also double up the ones that are enclosing the values, resulting in an error during upload again.So yeah, what I need to get done is single out all the values with regex ($1, $2 etc.) and then string.replace single quotes in those values but *only* if said single quote is not preceeded or followed by another single quote, else it would become a tripple quote resulting in an error again.
I am currently using the following code to check for the presence of an entry in a table. I choose this code because I thought it was a good idea to use a public function to reduce the amount of code required. It works fine until the field I am checking for contains a' character.I realise I need to use a parameter like @name but cannot work out how to pass the correct information to the public function.how to amend my existing code so I can use @staffNo.
Imports System.Data.SqlClient Dim PaddedStaffNo As String PaddedStaffNo = (TextBox2.Text.PadLeft(4, "0"c))[code].......
Is there a way I can check the place of the character in a line or string? For example: I want them to guess 1214 So how would I make sure each character is in the right place?
I am working on a solution to a problem at work where we can't tell if someone is on the phone or just sitting there. We use Microsoft Lync to place our calls and I was hoping to be able to add a bit of code to an existing .net application to show the presence of the person logged into the machine. That info will send that out via USB to an indicator light I previously built.
So basically I am trying to create a .net version of those 'ON AIR' lights you see at radio stations.
I have been searching for the last few days and haven't found a solution. I also downloaded the Microsoft Lync Controls SDK, but no luck with that either.

Is it possible to have a Radio button list, like we have a checked List box?Actually I want to load all the options from database to the list but do not want user to allow to check more than one item.
Also how to read it (say item 4 of the list) I want to store its value in the variable.
I'm making a program to keep track of my gaming accounts and the characters that the accounts hold. So I made a class called "Accounts", made it a Datasource to a listbox.
[code]...
So this is what I have. What I want to do, is have 2 Listboxes on my form. one Listbox contains the list of accounts, and the other contains the list of character that the selected account holds. I'm wondering how do I do this through Bindingsource? I got the Account class bound to a Listbox's Datasource, now I need to figure out how to put the List(Of Character) to the other Listbox
net application. .exe generated is sufficient to use software. since I have 700 MB (~8k media files) data to include as part of installation I do not want to use visual studio deployment wizard.
