Loading Data From A Xml File?
Jun 10, 2011
I have an xml file called "QuotesxmlDoc", in my program I have written code for a search screen that searches the xml file for titles or keywords in quotes saved and the information is then shown in a datagridview, see the code below:
Private Sub btnSearchQoutes_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearchQoutes.Click
Dim xmlnav As XPathNavigator
[Code].....
On the main screen of the program, I want to show all the saved quotes from the xml file in a datagridview, I just need to show the date, category, author, title of the quotes, I also need the datagridview to refresh everytime a new quote is saved.

Our application is using VBSQL.OCX on Sql server 2000 to create temporary tables and load pipe delimited data from a text file with predefined format into the tables. It is failing intermittently doing this. 99% times it works perfectly. But on occasions it does fail with error. Once the process is rerun with the same input file it runs successfully.Basically the architecture is of Store/Head Office where there are around 200 remote stores sending set of data files to the Head Office. At HO our application sequentially processes each store which has all the set of files received, creates a corresponding table, loads the data from the file into the table and moves onto the next store.If it is for some reason not able to load the file for a store, it gives a failure message and continues with next store.Error which the OCX throws is "Attempt to convert data stopped by syntax error in source field"

0000710950,INFEED NAME,40,INFEED TIME,0,ENTRY,55649,MCS,[code]....
What I would like to do is read this data in as fast as possible either line by line and processing the data as I go by line. Or read the whole lot in and THEN process it, which woulkd be the fastest ? I used to do this in Excel but want to transfer it to VB and don't know really how to get started I have the following but would like to know how to get the columns into a named array and then how to itterate through array.
Dim myLines() As String = IO.File.ReadAllLines("C:SYNC_DATA�0 - LGW�5 - Archived�0 - IST Logs2008istlog20090224.txt")

Ok here we go again, im a complete beginner to coding and have started with visual studio 2008 using the .net/vb libraries, as my first project i went with an emulation application, and it went great:So now i think its time to move onto a little more advanced tech's, so i added in a combo box and i want to change how my code works, and this is where my troubles are.To start of with the combo box, i have it added to my winform and have 3 items on it 'Action' 'RPG' and 'Sim' and i have made 3 .txt files in the projects root folder with the same names. What i want to have happen is when the user selects for instance 'RPG' from the combo box the items displayed in the listbox change to the contents of the rpg.txt file. After searching around for a few hours and no luck i tried this
Private Sub ComboBox1_SelectedIndexChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ComboBox1.SelectedIndexChanged
If (ComboBox1.SelectedItem = "RPG") Then

It needs to be as fast as possible. how i can optimize the loading of the data? I once loaded this data in a datatable and it took days.. then i exportet it as xml data and loaded this xml file with the data. this was about thousand times faster.

Try something along these lines:
TextBox1.Text=(dt1.rows(DataGrid1.CurrentRowIndex).item(0).tostring)
where dt1 is the datatable you're using as the data source and you want the data from the first column of the grid to be shown in the text box.
dp.SyntaxHighlighter.ClipboardSwf = '/dp.SyntaxHighlighter/Scripts/clipboard.swf'
dp.SyntaxHighlighter.HighlightAll('381571b4631840c6b8a8abfe5b54ed97')

RichTextBox1.LoadFile("c:pic.jpg", RichTextBoxStreamType.PlainText)It seems like it loads the data correctly, but the data is all wrong. I know this because when I use a packer sniffer, the data of the file that I sent is different when I sent the file manually.ou can also try RichTextBox1.SaveFile("c:pic.jpg", RichTextBoxStreamType.PlainText) after the picture of the data has been loaded and the picture becomes corrupted (won't show any picture anymore)

I'm writing a forms application. I'm adding a piece that allows you to double click on a row of a datagridview control to open a new form with more details. These additional details are pulled from a database, which takes a bit of time to finish.If I run the DB query from the form's load event, the form doesn't show up until everything in the load event has completed, which can take several seconds.I want the form to show up instantly when you double click, and all of the fields to be populated once the data is ready.Is there an event I should be using other than Load?
