I've made a browser project and beyond making it a default browser, I am having a problem with the Favorites feature TreeView control saving, loading and repopulating it with the users data. It's tough finding the correct code as there are so many variations of this control in various languages, but I did find sample code for loading and populating the TreeView with a text file using tabs to signify the node structure in VB.Net. (Most others I have found are VB6 or some other variation.)
I am looking for ways to retrieve data from textfile and save it into access database. Currently, I am doing a attendance record project. I need to save the attendance record which is given in a text file to the database. The version of VB i using is VB 2008.
The content of the text file look like this: E010,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR E022,2009/06,06/29/2009 7:44:45AM,06/29/2009 15:00:55PM,JUR
[Code]....
I tried to create a class and store the record but it just don't work.
I got a question. I have a textfile name membership.txt and using vb2008. However my code found error when try to grab the data to an array. I use delimiter "|" to separate between each data in line to save in specific column in database.
I have a simple textfile which I want to drag-drop into the treeview. After the drop read the textfile (line by line) and create the nodes. There are no subnodes (what-so-ever). File looks like this:
I just wondered if it is possible to save multiple text boxes as one file.Currently I:
a ) haven't woked out how to save a TextBox atall and have had to use Rich Text Boxes for this purpose and have used: RichTextBox1.SaveFile("Something.txt")
b ) Haven't worked out how to save/open files as one file. I have had somebody suggest to me using Arrays but I do not know what this meens
Private Sub LoadButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles LoadButton.Click Dim lin(8) As String, filRead As StreamReader, i, x, t, d As Integer

I am getting a run time error it is not saving to textfile
Everytime I go to save my listbox to a file (the same text file each time) I'm trying to overwrite the file (old list) with new file (new list), but it just adds my current list to the end of the list that was already in the text file to begin with..
when you have a textbox and you save the contents to a file : My.Computer.FileSystem.WriteAllText(SaveFileDialog1.FileName, TextBox1.Text, False, System.Text.Encoding.ASCII) and you open the file in notepad, you will see instead of multiple lines one long line and where the vbNewLine should be, a small square symbol.
the simple reason is: even if you write a vbNewLine or vbCrLf to your textbox, it will be reduced to vbLf so when writing the textbox.text to a textfile it only writes the vbLf where you would like to have a vbCrLf
so all you have to do is replace the vbLf with vbNewLine :
Dim days_in_clc_month(10) As Integer days_in_clc_month(0) = 30 days_in_clc_month(1) = 29 days_in_clc_month(2) = 30

i just need to get this block of codes out, and put it in a textfile. and my program will run without seeing it, because it's all saved in the textfile.
has anyone come up with a with a way to save a treeview without using a BLOB, I have some items that are 8-10 levels deep on it. if I could export it to xml and back again that would be ok, I need to store its info in a databse cell set to memo. but I need to inport the text from the cell and insert it back into the treeview, then when I save i need to save the data back into that cell.

Oh No, I've got 13 PC's in the House and 7 are in my bedroom and my main one exceeds this set of stats.
finding a solution on how to save a four level treeview on each table in the database? each level must be saved in the table w/c includes their parent-child relationship.
What I'm working on now is a basic telephone directory.a Directory text file contains the names of all of the subdirectories.The subdirectory files contain the names and numbers of all of the students/employees etc.Anyways. I've actually completed the program itself I just need to get the output formatted properly.Which leaves me with my problem. I want to output the data to some sort of grid. I'm going to assume DGV since it allows my to name columns(the column headings are simple: Name and Phone number)However, I cannot figure out how to take data from a textfile and throw it into the DGV. I know how to do it for a listbox, But I don't want a listbox since it isn't a grid. is there any way I can read my textfile data into an array and then iterate the data and output to the datagrid?
I am trying to create a textfile and write some lines into the textfile. However, the code that i am using can only write when the textfile is already created in the directory.
For this case, can i actually allow my script to search if a textfile is being created, if not create a textfile ???

I need to create an XML doc that I can call up and populate a treeview with. Can someone show me that basics on doing this. A simple example will suffice. Note I am not using XML-speak for any of this description. Assume I have some unknown number of Types (Parent Nodes). Each Type has a possible of Three Groups (children to Type nodes). Each Group has an unknown number of randomly names Cases (children to Type nodes). I want to create this XML file, save to a directory and the open again later to load into a treeView control.
I'm looking how to save the checked checkboxes in a treeview which contains a lot of folders and subfolders.Is it possible to save them in the application settings ?
This is one of those problems where there just doesn't seem to be anything of use on Google.Does anyone have any code snippets of how to achieve this? This thread: url...links to a solution but experts exchange has been a paid for service for a while now.Ideally, the solution needs to be able to handle any number of parent/child nodes.
What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g. Text File: link1 - 0 link2 - 0 link3 - 1 link4 - 0 link5 - 1
Then I will read the data with: Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click OpenFileDialog1.Filter = "*txt Text Files|*.txt" If OpenFileDialog1.ShowDialog() = DialogResult.OK Then Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName) Dim Lines() = Split(AllText, vbCrLf) [Code] ..... Am I going completely the wrong way about storing the data after importing from a text file?
I have a problem with reading data from a textfile called RESORT.TXT

I can't seem to figure out the datatype for the phone number? It displays in my listbox, but I only recieve the number 6 and the not the full listing of the phone number 604 777 1234.
What I want to happen is that the button from my system will remove the previous data from database and then insert new data to database from text file. Im done with inserting new data. The thing is that I dont how to control or where to put the Delete Command from my code.
[code] I'm trying to load a textfile with (formatted, mostly tab delimited) data, into an arrayList.To manipulate and extract certain data I was able to search through the arrayList and retrieve the needed data.This is what's not working: If I have found my needed data in certain places from the arrayList, I would like to split this to read the needed values. Trying to do this I constantly get string cannot be converted to 1-dimensional array of string errors. [code]

I'd like to export a table from Access to a text file (or a spreadsheet) using VB code in Excel 02. I'm using the transfertext command but my code runs through without actually doing anything or throwing up any errors. If I swap the code round and change Export to Import and move the data into the text file manually then the code will happily import the table into Access.
Sub Export() dbfile = "C:XLSMDBTable.mdb" Dim a As Object Set a = CreateObject("access.application")
