View 3 RepliesNot Reading All XML File - Repeating The Same XMLElementName It Only Seems To Read The First Element
Jul 22, 2009I have an XML file, shown below:
Code:<?xml version="1.0" standalone="no"?><!--RISInsight server settings--><Configuration> <Server> <ConnectionMode>ServerName</ConnectionMode> <ServerName>(local
[CODE]...
The problem is that I want to read the complete XML file, however because I am repeating the same XMLElementName it only seems to read the first element, the code I am using is the following:
Code: Dim reader As Xml.XmlTextReader = New Xml.XmlTextReader(Application.StartupPath & "settings.ini") Do While (reader.Read()) Dim addToList As Boolean = False Select
[CODE]....
Is there a way that I can make it continue to read the XML file?

View 7 RepliesReading File Names And Filling A ComboBox?
Sep 15, 2011I tried the code below but unfortunately, all i get is a combobox with U,s,e,r,s, as each line in the items collection and not the filenames of the relevant files.
the DirGetPath("Users") Function below returns my default document and application paths and appends "Users" to the end as the relevant files are stored in that Folder.
All I get is a combo box with the items as U, s,e,r,s (i.e. Users spelled out).
I tried all of the following as alternative methods too:
System.IO.Path.GetExtension()
System.IO.Path.GetFileName()
System.IO.Path.GetFileNameWithoutExtension()

View 14 RepliesC# - WPF UI To Allow User To Build A Complex Query And Output An Expression Tree
Dec 29, 2011What I am about to do build is a UI that will allow a power user to build complex queries.
This is non-trivial, but very common. So before I re-invent the wheel, I would like to see if anybody can point me to some already-written free code or release some of their own.
Required:
To be able to specify some 'where-clause' type logic like this: Age>21 and (Citizen=True or HasGreeCard=True) but without having to type the query code, instead, use a UI with constrained options and on-the-fly syntax checking (e.g., no unclosed parenthesis or ending a term with an Operator).
I've seen this type of thing in many line-of-business apps, where you can say 'add condition' and another line appears on the UI like this:
Dropdown of fields Dropdown of ops (=, >, etc) Blank box for entry
And you can add more lines, and the lines are all and'ed, but you can also decide to OR a few, or insert parenthesis (explicity or via indenting), NOT a line, insert, delete, and move lines around, etc.
Not required but nice:
WPF - I could convert from winforms. Extensibility using OO constructs. Validate the sanity of the query. Emit a System.Linq.Expressions expression tree - or similar data structure. If it attempts to execute the query I don't need that; but I don't mind removing it.

View 1 RepliesControl The Element Names Of Serialized Subclasses?
Jul 5, 2011Let's say I have the following class structure (simplified from my real-world problem):
Public Class PC_People_Container
Private _people_list As New List(Of PL_Person)
Public Sub New()[code].....
If I were to serialize this, I'd get the default assigned node names in my XML. That means my root is named PC_People_Container and each person in the list is marked up as PL_Person. I know I can change the root node using <XmlRoot(ElementName :="PeopleContainer")>. The trouble is doing that for the subclasses. I can't use the <XmlRoot> tag on PL_Person class because there can't be two root elements, and IntelliSense throws a fit when I try to use the <XmlElement> tag on a class like I would on a property. Is it even possible to control what those subclasses are named when they're serialized as child nodes?

Writing Array Of File Names To Text File
Mar 11, 2010I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.

Reading A Specific Line From A Text File And Displaying It In Individual Text Boxes?
Feb 16, 2010I've been writing a weight program for flooded pressure vessels and I'm having trouble retrieving the data from the text files I've been saving. I know how to write the data to the text file, but retrieving it with OpenFileDialog is not so easy for me.The user has individual text boxes that they input strings or numbers into and when they save the file, each text box input is written to one line in the text file. For example, the first text box is for the username, therefore the first line of text that is saved is the person's name, the second text box is the customer, thus the second line in the text file is the customer name, and so on.
(Actually, the first line of text in the saved file designates whether English units were used or Metric units because when the user retrieves the saved file, English units will open one form and Metric units will open a separate form, so some If...Then statement will need to occur).I need to be able to read the first line, have either my "EnglishForm"form open or my "MetricForm" form open, and then have each subsequent line of text be displayed in their corresponding text boxes. I know I need to use ReadLine or LineInput, but I don't have a clue what to do.Assuming the syntax I've displayed below would just magically work (if only life were that easy), it would look something like this
If FirstLineOfTextInFile = "English" Then
EnglishForm.Show()
ElseIf FirstLineOfTextInFile = "Metric" Then[code]....
And so on...I read a lot of articles from the MSDN library and exhausted each link that I've looked through from Google and Bing, but most only retrieve data from the file to a single text box through some loop or streamreader and don't take into account multiple forms.

The txt file is set up in one column and holds the member name and the next line is member number and so on.

I had it displaying all th txt file info and I just need the names.

Though it could be too many hours spent trying to get it to work.

Jun 14, 2011I am trying to import a TAB (NOt comma) delimited text file into a DataGridView. The following code works fine if I have a comma separated file. All I have to do is change the FMT to "Delimited".It just does not work with FMT=TabDelimited. All columns are read into single datatable column. The text file is ANSI text and I have double checked to make sure Tabs are tabs and not spaces, even exported a sample Tab Delimited file from Excel.Can this even be done using Text Driver? [code]
