Get String Between Indexes?
Jan 13, 2010
I've been searching for hours trying to make a Button event that removes all the text between two indexes in a list box. The two indexes are #FIRSTNAMES# and #LASTNAMES#... I have a code but it's WAAAY too confusing and it does not work. If anyone knows a way to do this, please let me know. I'll post my code just in case you don't know another way. I haven't gotten to the remove part, I'm still just trying to display the text between the indexes into a message box. I took most of it from Google pages... I really want an easier way, because I know there is one, but never the less I just need progress.

Just like the title says; I want to use something like Mid(stringName, startIndex,[integerLength]), but instead of the third argument taking a string length, I want it to take the end character index. So in an example like this:
alphabet = "ABCDEFG"
partial = *method I want to use*(alphabet, 2, 4) 'partial would equal "BC"

A very basic problem, sorry but I am new to .NET! I have a blank form that I populate say with 8 PictureBoxes (it doesn't matter what the control is, I've just picked one at random)In VB6 if I want to change any property of these controls, its very simple, because I can index the control eg:
For i = 0 To 7
MyPic(i).BorderStyle = 1
Next
How can this this be done simply in VB for any control in general?

I need to create a collection that should have named indexes. e.g.: IN typical collection such as ArrayList :
Dim al as ArrayList = New ArrayList() al.Add("10") al.Add("20")
to access first element i have to use "0" in al(0)...such I need to create a collection that has Named indexes instead of Numerical zero based indexes. such as: assume the collectio object is col1. to access the value element "RegoNo", i should use the collection object as col1("RegoNo") or similar technique Is this possible to do?

Sometimes(not always) I get that internal index is corrupted. I read somewhere that frequent updates to in memory datatable, can produce error like that and that only real solution is to create dataview from time to time, and by doing that datatable rebuild it's indexes...is that for real....I have changed my code and now I'm creating dataview and disposing it right away...so far so good. but I was wandering is thatfact....does datatble rebuilds it's indexes when you create dataview...and if not when are they rebuild.

Public Scores(19) As Decimal
Now This Array is populated with decimal values and i just want to get the index values of the highest and lowest scores.i.e. if the [[scores(3) = 90]] and [[scores(7) = 90]] are equal and highest scores, i want 3 and 7 as integers in return..and same for the lowest scores..I retrieved data from a text file and stored it in Classes.. now i want to relate the above Array and these Classes..
Dim Student1 As New Student
There are total 20 of these classes.. Student2.vName, Student3,vName.. etc etc
Student1.vName = SplitterArray(0)
Student1.vID = SplitterArray(1)
Student1.Score1 = SplitterArray(2)
[code]....
For example, After i get the highest score indexes from scores(19) array i would like to get the name of the related person from Student*.vName Class (If i get 3 and 7 index i the related names would be Student4.vName and Student7.vName consequently)?

I've used visual basic in office before, but when it comes to writing applications in Visual Studio, my knowledge is fairly limited. I'm unsure on how to set up a connection in my application to connect with a dBase IV database that uses indexes (not sure if it matters if it has indexes or not). I will need to both read and write to this database.

I am developing an application in VB2008. I initially starting using Office 2003. But later found out that I need to develop it using Office 2000 automation instead.
The problem is when I developed it using Office 2003 I was able to reference the bookmarks by name like this:
Code:
Dim data As New DataObject
data.SetData(DataFormats.Rtf, pubrtfContent)
Clipboard.Clear()
[Code]....
Why would just changing the references in the application cause the bookmarks to be referenced by numeric value only, instead of name? And how I can I get the bookmarks to be able to be referenced by name in Office 2000? Obviously I am doing something wrong, but can't figure out what.
Btw, when I try and reference a bookmark with the name in with the Office 2000 references I get this error: Conversion from string "Judgement" to type 'Integer' is not valid.

I have a class project that I have been working on for a while, and I can't figure out how to add each cost from lstCosts together to show a total cost of the selected workshops in lblTotalCost. Using the current loop that I have, it only adds the last cost in lstCosts. Is there a way to add the indexes together?
Code:
Public Class Form1
' The registration fee for each workshop
Const intSTRESS As Integer = 595 ' handling stress
Const intMANAGEMENT As Integer = 695 ' time management
Const intSKILLS As Integer = 995 ' supervision skills

I'm building a virtual blackjack game and I'm having difficulty assigning values to the cards. I've set up picture boxes for the dealer's cards and the player's cards, and i've linked those picture boxes to an ImageList that contains all of the cards (+ the picture of the back of the card, since you only see one of the dealer's cards to start out with). When you hit the "Deal" button, I have the following code so far:
Private Sub btnDeal_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnDeal.Click
Me.btnHit.Visible = True
Me.btnHit.Enabled = True
I have a section at the top that has labels saying: "Dealer's Showing ______", "You're Showing ________"how to assign values to the indexes/items of the imagelist? For example, items 0-3 have a value of "2", items 4-7 has a value of "3", and so forth...

I am using a select case loop to perform different tasks, one of the tasks the loop is doing is putting 1d arrays together into 3d arrays. But, when i come to print the 3d array only the 3rd "line" in the array is complete. Is there a way to pass variables created in a select case out of the select case?
Here is some code to try and explain better:
Select Case Int()
Case Is = 13

i have to convert a visual basic 6 program to the visual basic 2008. i used the wizard that is provided to upgrade but that just doesn't work. It comes up with many errors. most of them are End of statement expected and Number of indexes exceeds the number of dimensions of the indexed array. I really don't know what to do with them and i have to fix them in order for it to run.

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.

Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything
