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.

VS 2008 Inserting A String Of Text At A Certain Position?

Sep 8, 2009

far it works! But it work's too well. What I'm trying to do is insert a string of text at a certain index position of a text file, underneath a certain line of text. So far I have:

'Controls Var 16
If CheckBox1.Checked = True Then
If Mytempstring.Contains("zrandomtextz=0") = True Then
Mytempstring = Mytempstring.Replace("zrandomtextz=0", "zrandomtextz=1")
ElseIf Mytempstring.Contains("zrandomtextz=") = False Then

[Code]...

It's inserting the text, but it's inserting it at every line of text in the file. So instead of one instance of "zrandomtextz" underneath "xinserttextx" I get "zrandomtextz" before every single line in the file. Can someone please help me as this has been an issue for months now? Edit: There are quite a few lines above this one, as in 50-150, so I removed all of the above section, however I can assure you that whenever it is simply replacing then writing to file it works flawlessly, it's only now that I'm having problems and this is when I try to insert new stuff under stuff.

Finding Information In A String

Oct 12, 2009

I think VB has a way of doing this, but for the life of me I can't find it. I want to search through a string for anything contained between two certain characters, e.g between 2 | characters. I'm not sure if I want to split the string at this point, but I only want anything contained between the two | markers. So for example if the string reads |ABC|DEF I only want to retrieve the ABC, but not the DEF as it's not completed yet.

Basically the program will turn the string "Will Smith" to "Smith, Will" But I noticed when I type in a name with a middle initial or middle name "Will J Smith" I would get "J Smith, Will" And I want to be able to find that second space when its there and apply a code that would produce "Smith, Will J" When there is a second space. How would I go about doing so?

Finding The Greatest Value In A String?

Nov 17, 2009

Ive got a question about finding the greatest value in a string. I am connected to a database but I am positive that part is right. So i posted here instead of there.

Dim x As Double
Dim ConnStr As String = "Provider=Microsoft.Jet.OLEDB.4.0;" & "Data Source=DBASE.MDB"

[Code]...

How do I make my If..Then statement return the highest value of row 0's x? My output (by changing the if then statement) will either return the first or last entry in row 0. I hooked up my code to a list box and got all the data to list perfectly i just don't know how to get the highest number after i use the formula for x (which is {c1-c2}/c2).

Finding Words Within A String?

Mar 31, 2011

Basically what I'm trying to achieve is to extract all the words within a piece of string and transfer that from one text box to another text box.

An example piece of the string would be

<laugh:894u8438:4434:words>

However the words within the string will never remain constant and the characters before and after will change. Is there anything that will read the string and take a word from the string without it being pre-programmed. The string it is reading from is uploaded from a text file.
