How To Find The Space Using Substring To Display Initials
Jan 27, 2012
The part of the program I'm trying to write is supposed to take the users input, which is their name, and in a listbox spit out their initials. I have so far:
Dim initials As String
Dim indexspace As Integer
initials = name.Substring(0, 1)
indexspace = name.IndexOf(" ")
lstInvoice.Items.Add(String.Format(strFormat, "Invoice ID", initials & space))
When I run the program, I can get the first initial to pop up, but I am not certain how to get the second to pop up.
Say you enter your first, middle and last name into a single text box, separated by spaces. I need to know how to separate all three names and get the first letter of each. and show it in a label.
I'm creating a file thats need to be in this format url... I need to be able to set the limit of the string length for certain fields.Is there an easy way to set the limit of the field so that if the string was larger then the limit then just take the substring and if smaller would add extra spaces?I was able to accomplish something similar to this with integers by just using .toString("00000").
It seems to work fine for a small text file but when I use files larger than 100MB it does not give me an accurate count.The program is pretty simple. It should return the number of occurences of a substring from within a text file. I look for a match to the first character of the substring and if found then my code should test to see if the whole substring exists.I have run several tests but for some reason I am not getting an accurate result. I used the windowsupdate.log file. My code trturned 34596 hits but when I used MS Word to find the number of occurences it returned 50096 [code]
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'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 want to find a space after a certain varying word
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If Textbox1.Text.StartsWith(a.Text & (" ")) = True And
[code].....
I want this part of my project to detect spaces because it can happen if the user puts in a certain value for on and that value begins with another it will not process. (ex. a.text = 123, b.text = 1234, then i get the outcome or "aa" and it should be "ab"
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:

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 am working on this exercise where i have to find suburbs with minimum and maximum percentage POS (public open space).i manage to get the minimum and maximum but i need a way to allow for two or more suburbs with same minimum or maximum..for example three subrubs ( suburb A, suburb B, and suburb C) all has same POS of 2%, then i need to list the three in the list box as minimum with subrub name(from my code i can get only one) with the maximum values as well( allow two or more suburbs with same maximum in a similar way)..below is the code.. i have removed some codes to make it read easy whi are not relevant.. i got POS percentage correct and i wanna start from there..
For intSuburb = 1 To pFClass1.FeatureCount(Nothing) 'SOME CODE HERE(this bit is long and is not relevant).............. dblPOSPercent = CDbl(Format$(((dblSumPOSArea / dblSuburbArea) * 100), "###.#0"))[code]......
How would i get a certain text inside a textbox to equal that text space to space or null to space?
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click If Textbox1.Text.StartsWith(Textbox2.Text + " ") And Not String.IsNullOrEmpty(Textbox2.Text) Then Textbox1.Text = Textbox1.Text.Remove(0, Textbox2.TextLength) Textbox3.AppendText("a") End If
Btw: after i finish this step my project will be finished!
How should I code to display the name in the listbox following this format: Lastname comma space firstname (foe example: Depp, Jonny), when the user input a fullname from a textbox( Jonny Depp)?
I'm trying to make the progress bar to display the amount of free space C: has. I have successfully do so with my code which is:
Vb.net Try Dim b As String Dim c As String Dim dvr As New DriveInfo("c:") b = CStr(dvr.TotalSize 1000000) c = CStr(dvr.AvailableFreeSpace 1000000) [Code] .....
As a last touch to this code I thought I would add a percent bar so it would look more professional. I did so with: Dim Per As String = (c b * 100) The problem is that it displays always zero percent why?
Trying to create a game that firsts asks for the users initials. Once the initials are entered the game from becomes visible. Can't seem to figure this out.
I am using a picture box. I want to be able to use the Space or Enter key to change the image in it. For that, I try to use the keydown function as follow:
Private Sub ChestWindow_KeyDown(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles Me.KeyDown Select Case e.KeyCode Case Keys.NumPad1[code]....
is the function which changes the image. It works well when I press '1' on my numeric part of the keyboard as a test.The issue is that when I press Space or Enter, the form containing the picturebox closes. (I've already put the keyPreview property to True)
I am trying to remove VB6 type code and use VB.Net code, in particular, remove "Left" and use "Substring". This code does not do what the old style code does. It seams to ignore the first two chars and forces the msgbox prompt no matter what I type in the textbox (at "Leave").
Private Sub TextBox5_Leave(ByVal sender As Object, ByVal e As System.EventArgs) Handles TextBox5.Leave If TextBox5.Text = "" Then 'Do nothing
I'm trying to write a function to find a word in a string in the this format : "ThisissometextthatIneedtofindandthisisthetext. This is another text."It's read as " This is some text that I need to find and this is the text. This is another text." but there is no space between each word. I want to get the word "text" or any word in that string. Can you help me with this function with a code sample ?
And I think that this method can be implemented with a string of Unicode also because in a sentence of Unicode it contains one or few, sometimes zero spaces between each word.
I have the following code: indexOfSearchText = TextBox1.Find(item, start, TextBox1.TextLength, RichTextBoxFinds.WholeWord) If indexOfSearchText <> -1 Then startindex = indexOfSearchText End If But I want just the first result, if I have an example text: then it searches twice "is", I just want the first "is".
Is there a way to tell the DISPLAY size of an image in a picture box? If the PictureBox.SizeMode=Zoom, the picture sometimes is not displayed as big as the picture box is, and is sometimes displayed smaller, or larger, than the actual image is. I just want to know what size it is actually displaying as.
I have a string which consists of the raw HTML of a webpage. I would like to search for the first use of /imgres?imgurl= within the string and display the url of an image which follows exactly after it in a text box. Below is an example of part of the string: [URL]..In this case it would find /imgres?imgurl= then it would display [URL]...
Does anybody know where to find a component for Visual Basic 2005 or 2008 that allow me to create level indicator, button, display or other special box used on a bridge of a ship? I want to simulate a small bridge of a ship and I need something that allow me to show engine power, rotation speed, level of pressure, compass and so on.
My objective is to find the lowest test score in the array and display it in the associated label using a DoLoop. However, I don't think I was to use the ForNext stmt.Could I have used the DoLoop without the ForNext? ' displays the lowest test score stored in an array
Dim testScores() As Integer = {14, 82, 94, 77, 11, 95, 38, 62} Dim lowest As Integer = testScores(0) Do For subscript As Integer = 1 To testScores.Length - 1
I have a table with fields "username", "Password" and "initials"I have this filled with data.I also have a login form "the login part works fine" but what I also want is depending on what username the user puts in I want the relevant initials displayed in a textbox.
I'm getting an ArgumentOutOfRange error when using substring function in .NET. I'm new to .NET so probably doing something wrong. I have a txtField, which is a text field component in GUI. I'm using Microsoft Visual Basic 2010 Express
I have a piece of code that I am using a for next statement and stepping through a string a little bit at a time. The problem is I get an error towards the end of my loop because my substring goes beyond the bounds of my string.
Dim Right As Integer = StartNumber.Value Dim left As Integer = LengthNumber.Value Dim i As Integer = 0
