View 3 RepliesI'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.

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

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"
I'm working in VB.Net. I have a textbox in which the user enters a number of strings seperated by comma. I store this value in a string array like this
Dim Src() As String
Src = txtVals.Text.Split(",".ToCharArray)
I want to search a dynamic string in this array. How could I do it in the fastest way?

I'm having a problem recently, a logical issue so hard to determine various examples.I need the text that is inserted in textbox, which has been altered or modified or twisted to have a proper format through line accordance and constant white spaces etc. And some cases I stuck at defining the If statement within the loop.

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.

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)?
