Parsing Xml Nodes With Attributes
Jun 22, 2010I need some help figuring out how to parse an XML file in VB.net so I can find a particular node and write the contents into a database. Basically all the data in the XML node below needs to be read into an object.[code]I've had some success playing around with some Linq code, but I'm not able to figure out a way to traverse the sub nodes, so I can read them into an object.[code]
View 2 RepliesUse All Listbox Contents For Filtering Datagridview?
Mar 11, 2010using all the listbox contents for filtering a datagridview2 (that is binded with an access database)
my code is as follows:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim tables As DataTableCollection = VPC_DatabaseDataSet.Tables
Dim view1 As New DataView(tables(4))
Dim source1 As New BindingSource()
[code]....
the code above is working, however, the datagridview2 only displays only the matches for the first entry in the listbox, which is 100101. it does'nt include the matches for the other two contents in the listbox.
VS 2010 Filtering Listbox From Combobox
Aug 31, 2011On the form, I have combobox1, combobox2, datagridview, and a listbox. Basically, combobox2 displays a list of street names. My problem is that once the user selects a street name from combobox2, the listbox should be populated with only the customers' names who lives on that street. How can I go about populating a listbox with just the customer names? Originally, the street names include the house numbers as well. For example, "5100 E Dublin Granville Rd". Fortunately, I figured out how to display ONLY the street names ('E Dublin Granville Rd') and not the full street address to the combobox by adding the following public property below. However, I am still encountering a problem because now the combobox has duplicates of the same street name![code]
View 3 RepliesLINQ To XML To Query Attributes Values
Oct 25, 2011I am trying to use Linq to Xml to query attribute values that will be used to populate a combo box. My xml looks like this:
<Records>
<Record id="1">
<LogoPositioning>
<Brand id="26">
<Xpos>100</Xpos>
<Ypos>200</Ypos>
[Code] .....
My issue is with getting the attribute values. I tried this:
For
Each xattr
As
XAttribute
In
attr
cboBrandChoice.Items.Add(test.Value)
Next
However, I keep getting the following error:
{"Unable to cast object of type '<GetAttributes>d__8' to type 'System.Xml.Linq.XAttribute'."}
I'm new to using Linq so this error isn't making a whole lot of sense to me.
IDE :: RTM Intellisense Not Automatically Filtering List Of Values?

View 1 RepliesFiltering Datagrid When Select Item From Listbox?
May 3, 2010I have a listbox and a Datagrid, both bound to a database. The listbox contains Names, and the datagrid contains the records of those names. I am tryin to filter out the datagrid, so when i click on one of the names , it will only show those records. Right now when i click on one of the names, it displays that record, but im still seeing the rest of the records from the other names. i know it something like
work_Order.DefaultView.RowFilter = "Name='" & NamesListbox.SelectedItem & "'".
datagridview1.DataSource = work_Order.DefaultView
work_Order = name of the table
Where would i insert the code in? on the form, or on the grid properties?

Parsing Values In Query?
Apr 24, 2012 Right now I have an array that is unparsed. One of its elements goes something like this:
"Blah, 555-5555"
So it's a name and a telephone number separated by a comma. The instructions I have tell me to use a query to put the information in the array into a data grid view in two columns, one for the name and one for the telephone number. I don't know how to isolate each inside a query.
Parsing And Getting Specific Values From CSV String?
May 20, 2010I am having a string in CSV format.http:[code].....I can add new values to it by some mechanism. Everything will be same except the new values will have numeric part = 0. Take example I have this exsiting CSV string
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt
Now by some mechanism i added two more files Superman.txt and Spiderman.txt to the existing string. Now it became
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt, 0, Superman.txt, 0 , Spiderman.txt
What i am doing here is that this csv string is paased into SP where its splitted and inserted to db. So for inserting I have to take the files with numeric part 0 only rest will be omiited .Which will be further then converted into CSV string.Array will look like this
str[0]="1"
str[1]="abc.txt"
str[2]="2"[code].....
So at last i want to say my input will be
1 , abc.txt , 2 , def.doc , 3 , flyaway.txt, 0, Superman.txt, 0 , Spiderman.txt
Desired Output:
0, Superman.txt, 0 , Spiderman.txt

Parsing ListBox Lines To Textboxes
Aug 2, 2010So in my form i have the user input a bunch of data that gets written to a listbox. Like so Pre_Study_Listbox.Items.Add("Team Members are: "). I then save the listbox to a .txt file and they can later load the .txt file back to the listbox. All this works great. But now i need to reverse the order of textbox to listbox and put the information back into the textbox fields from the listbox. So. The parsing character is ":" I need to read each line of the listbox and at the ":" take the rest in put it to the text box. I am not familiar with the parsing command

Parsing String Each Iteration, Or Parsing Once And Storing?
Mar 16, 2011I'm creating a vb.net winforms application that will take in user given strings, parse them, and print out labels with variable information. The given string will be used in all the labels, but the variable part of the string will change with each label.
My question is: is it better to parse the strings one time, then store those values in arrays, or to parse the string each time a label is printed? Which will perform better? Which is better practice? What is the proper way to test something like this?

The entries that are needed are then selected via checkbox in the listbox. I now need to be able to capture which items the user selected.
