VS 2005 Reading An XML-Type File?
Jun 22, 2010
I am trying to read in and eventually manipulate an 'XML-type' file. I have picked up a hobby called 'Geocaching', some people probably have heard of it, where you use gps coords to locate items placed by other people. Well, you can download the gps coors within data files from the website,'Geocaching.com' and these files are in a XML format.
There are a lot of programs out there that people offer, some are better than others, but I am not happy with the results. So, I am trying to see how I can use these files myself and create my own program to use the data in a way that I want to use it.
I have tried to use Linq, XMLdocument, XMLreader and probably a couple of others over the past week. I have had marginal sucess with each of these methods, but nothing great and I owe that to my lack of knowledge.
I eventually hope to add the data to a Access db that I am using and manipulate the info from the db.
I am attaching a sample of one of the downloaded files and if someone would have the patience to help me work my way through it, p.s. The file typically ends with '.gpx', but since its an xml and thats what the system recognizes, I added the extension in order to upload the sample file.

Normally CSV files I work with lookes like this : d,e,f,g,1,2,3,4,5 What I am trying to do now is importing a CSV file that contains a title field, HTML description field ect. so at the end the CSV file format looks like this:"Record Title",1,2,3,"HTML description, which contains "",, ect",1,2,3,4,5, I need to know how to work with the above CSV format, where all the strings are inclosed with "" and may contain commas, so I can't use the split function as is to split where it incounters a comma as it may be part of the HTML description or Title field.

My program reads a 3rd party .txt file using OleDb and reads the file into a datatable. It's overall working fine except a user will occasionally have a problem reading a file. At this point.
Line that gets hung up
Try
Dim comm1 As New OleDbCommand("SELECT * FROM " & safeFileName & " Where " & Status & " = '" & StatusClosed & "'", con)
Dim dasold As New OleDbDataAdapter(comm1)
dasold.Fill(dtsold)
AddColsold()
[Code] .....
It can not retrieve a date for one of the fields, then gives error and does not get dates for each records after the one it gets hung up on but the date is in the file. If I open the file in excel and play with the column sizing, for instance just autoformat column width then it read the date and will work fine. I have looked at the file in notepad and cant see anything wrong in particular on the record it gets hung up on. I have no control over the .txt file since it comes form a 3rd party.

I'm reading a file into a buffer using the Space function. Then I'm using blowfish dll's to encrypt it, and want to write the encrypted data to a txt file. (I realize you can use .NET cryptography classes, but I need to use these old blowfish dll's for this project.) Anyway, when when I encrypt the data in the buffer, I can see all encrypted data, but when I write it out to a file, I get a few lines of encrypted data and the rest of plain text.

I'm trying to read a csv file with comma separated. Problem is inside the file, it has one column which original value already contains Comma. Here is the example
[Code]....
So, when I Split the string with Comma, it gave me problem. Actually total it has 6 columns. But because of internal comma, it gave me 7 columns. And this CSV format can't change so I must deal with this problem. And so here I come out with a solution (because of its too long, I looking for better idea and solutions from you guys ):

I have a form with a listbox. I'm adding items to the listbox through a file that I saved. When I open the file, I want each line/string in the file to go in as a separate item in the listbox. I've gotten it to work so far but only with 1 string. I need to loop the part where the file is being read to be able to add all the strings that are within the file to the listbox. How do I do this? So far, this is the code I have:
VB .net
Private Sub OpenToolStripMenuItem_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OpenToolStripMenuItem.Click OpenFileDialog1.Filter =

I am new to VB but I do have VS2005 and I was looking at some code examples here on deleting files by days old and I need to do something similar, I would like to start a say C:myData**.xit and search through all sub folders under myData and move all the .xit files based on days old into a temp folder. Then I could verify them before I delete them manually to be safe. So how do I loop through all sub folders? and can I just modify this code to do that? Here is the code I was thinking about starting with [URL].
Dim files As System.Collections.ObjectModel.ReadOnlyCollection(Of String)
Dim singlefile As String
Dim CreatedOn As Date
'Declare the counter
Dim deletedcount As Integer = 0

I am trying to open an Excel file using the following commands:
xlsWB = xlsApp.Workbooks.Open(filename, , True)
where 'filename' is the name of the file.However I am getting the following error message:
Message = "Old format or invalid type library. (Exception from HRESULT: 0x80028018 (TYPE_E_INVDATAREAD))"
I originally developed an application where I used the above code with default language setting of "English" (under regional and language settings). When I am changing the language setting to "French", the above errror comes up. I am changing the language setting to French in order to simulate an error when this application is run in a French version computer.

I'm in high doubt of this actually exsisting but still want to check, is there a way so that whether the VB form has focus or not it can still read the keys being typed? I am using winamp and i type something and the form picks it up, so when i type something like ctrl+"exit" the application closes. the thread should be running as the form is Always on top, however for obvious reasons the form does not have focus, so something like keyPressEventArgs won't have an effect, is there any way that you can catch the keys in a global perspective.

I need to write data to a file, preferably in binary format, but I am unaccustomed with the concept. Where's the easiest place to get the basics? I could come here with a specific need, but I'm at the point right now where I am more willing to work within the confines of keeping it simple.
Here's what I know:
1. how to open a new file
2. how to specify the record length
3. how to close the file
Some specific questions:
Does the record length have to be constant throughout the file?
Can I read the nth record without reading the whole file?
