I'm trying to split a Yahoo historical stock price csv file, downloaded into a string, by what looks like a space character. I want a new row for each split.

Split A String Using Followed By A Space As A Delimiter?

Jan 11, 2012

I have an string that is returned from an xml file and looks similar to this name1="test 1" name2="test2" name3="test 3".I want to split this into 3 elements of key=value. I can't just split using a space because some of my values may contain spaces, e.g., test 1.So, I'd like to split the string using the " before the space. I've tried many variations but can't figure out the correct syntax to specify that my split characters are a " followed by a space. For instance, I've tried text.split({""" "}) but that returns elements split by " and ignores the space after the ".It shouldn't be this difficult. Can someone please help me with the correct syntax?

.net - Substring And The IndexOf Function

Oct 9, 2011

substring and the indexOf method

I have this problem that I'm going in circles on. The error message is "no accessible IndexOf can be called with these arguments."

My professor said that "to search for the string Los Angeles and substring will return it from the textbox, but it needs to know what position to start returning a word at, and that is where the IndexOf comes in." Does that mean substring and IndexOf are used together? That's what I did and may be the problem. Here's the code:

Private Sub btnOrder_Click(ByVal sender As Object, ByVal e As EventArgs) Handles btnOrder.Click
'Declare variables

Substring And The IndexOf Method?

Oct 7, 2011

My assignment in Visual Basic 2010 is to build a order form that has two text boxes, one for the name and the other for the address. And we're suppose to use the IndexOf method on the address. I understand that IndexOf returns the position of a character and the number of characters. What would be the purpose of using the IndexOf method on the address in this instance? I don't understand what I would be searching for when the user types in it's address that's going to be numbers and string characters. I think I understand what the IndexOf method does, somewhat, but why and what would I use it to achieve?

Keydown Space/Enter - Use The Space Or Enter Key To Change The Image In It?

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)

Treeview Node Indexof() Not Working?

Sep 29, 2009

I have created an object hierarchy with nested generic listof() structures. I have created a treeview to match and graphically show the structure. I needed a way to show a property box of an object represented by the selected node on the treeview. So, I gave each of my objects a NodeIndex property, in which I would store the treeview.indexof(node) result, as shown below:

For Each oObject In oJob.ObjectListOfCollection
tnode = New TreeNode(oObject.Name)
Treeview.Nodes.Add(tnode)

Finding The Position Of Certain Delimiter Using String.IndexOf?

Jul 28, 2009

What would be the simplest way to find the n-th position of delimiter in a string.For example, say, I have a string variable called FullFilePath that contains the path of a file, like, C:SourceFiles<mthyr><subject><filename>.txt From this, I would like to extract out mthyr, subject, and filename, using the delimiter, "".

I was hoping string.IndexOf would let me find the n-th position of the delimiter "", in which case I can use the result to do a string.Substring. But it looks like IndexOf only finds the first occurence of a certain string, which means I would have to interate this somehow to look for the n-th occurence.

Or is there another method that will help me do this more efficiently.
