When i save data in my xml file i save a bunch of cities that the user has selected, i then proceed to load the data back into the program and populate the check fields besides the city
vb.net
'// Loop through each one and re-check them
For Each cityToCheck As Xml.XmlNode In nodeList
[code]....
This string stringSplit(0).tostring returns the city name say "Glasgow" i was trying to loop the listview that stores the cities, if they match then put a check mark, this is where the cities are located: (formAddCities.listViewCities.(FIRST ITEM IN COLUMN WHICH IS CITY NAME) the very first column in the listview, but i can't seem to get the right syntax?
I want to know how I can check the string 'enabled' in my php page for each paragraph while being matching with each listview items that i have extract the strings from my php page?
Here's for an example: i check the string 'enabled' in paragraph one and if it does have it then tick the checkbox on the listview item 1 otherwise untick.
i check the string 'enabled' in paragraph two and if it does have it then tick the checkbox on the listview item 2 otherwise untick.
i check the string 'enabled' in paragraph three and if it does have it then tick the checkbox on the listview item 3 otherwise untick.[code]...
Say I have a List(Of Tag) with Tag being an object. One member of Tag, Tag.Description, is a string, and I want to make a comma-separated concatenation of the Description members.Is there an easier way to do this than to read the Description members into a List(Of String) and then use the Join function?

I am working on a UDP Client/Server, and currently i have them sending back and forth strings, which i convert to bytes, and then open the bytes to read. I want to now send an Object instead of those strings, which includes multiple unsigned integers and strings.
View 39 RepliesI have a list of strings. For each string in that list, I want to prepend another string. I wrote a method to do it, but I was wondering if there was something already in .NET I could use to do this. It seems like something that could be built in, but I was not able to find anything.
Here is the method I wrote:
Private Function PrependToAllInList(ByRef inputList As List(Of String), ByRef prependString As String) As List(Of String)
Dim returnList As List(Of String) = New List(Of String)
For Each inputString As String In inputList
returnList.Add(String.Format("{0}{1}", prependString, inputString))
[code].....
It works, but I would rather use built in functions whenever possible.
I'm migrating from VB6 to VB.NET, in hence my questions below:
I have to write a function that returns array of strings.
How can I initiate it to empty array? I need it since I have to check if it's empty array after it returns from this function.
Is list of arrays better for this purpose? If I use a list - Is it empty when it firstly defined? How can I check it it's empty?
I have been looking for examples to find the string between two strings. This top one works fine;
Public Sub ReadData(ByRef keywordStart As String, ByRef keywordEnd As String, ByVal filename As String)
Using reader = New StreamReader(filename)

Now the first one is fine - Ext_Volume is result of the string between the strings <Volume> and </Volume>. <Volume> and </Volume> are unique so this is straight forward.
However the second one - "^FDExp:" is unique, but "^FS" is not unique. There are occurances of "^FS" before and after "^FDExp:".
How do I get the string to search AFTER the occurrence, not before etc?
Dim str As String
Dim str2 As Array
str = "blabla duhduh"
str2 = str.Split(" ")
Say the string is something like
bla bla bla bla (cat) bladfdskdfd dsgdsdksf (dog)
dfdshfdskdskfsdfkhsdf sdkfhdsfkdf (kathy) fdsfhdskfhdsfkd (doggy)
I want a generic.list (of string) containing
cat
dog
kathy
doggy
How to do that with regular expression in vb.net
Later I want to do something more complicated like getting all strings between "url":" and ", from this strings

Is there an easy way to find a certain string within a string and then return the strings that you find as an array?I have written this:
Public Function FindStrings(ByVal strSourceString As String, ByVal strStartString As String, ByVal strEndString As String) As String()
Dim StringStartposition As Integer
Dim StringEndPosition As Integer
Dim Currentposition As Integer = 1

View 2 RepliesI have a DataGridView that has some columns with dates. It binds to an in-memory Datatable which gets loaded from an string array of data passed back from the backend Some of the rows returned have nulls for the date columns. Solution 1: If I define the Date column in the DataTable as "string" I can easily convert those nulls to empty strings and display it in the grid as empty strings (desired results). However, if the user clicks on the date column header to sort by date, it doesn't order the rows as you want. You get a purely string sort order. Not acceptable

I have a media browser program I am building. I am trying to use drag/drop so a user can drag media tracks from one listview to another listview and then use the second list view as a playlist in windows media player com object. Reading at MSDN I have found out that there is no built in support for item re-ordering with the listview control. I have listview1 working correctly but when I try to reorder items in listview2, the dragged item ends up at the end of the list. So basically I need to get the item insertion index corrected. I have tried more than 10 times to get this code right.
Here is my code which includes a form with two listview's.
Public Class Form1
Private Sub ListView_ItemDrag(ByVal sender As Object, ByVal e As _
System.Windows.Forms.ItemDragEventArgs) Handles ListView1.ItemDrag, _
ListView2.ItemDrag

I would like to know if it is possible if the columns of the listview can be resized automatically based on the information in the listview?

View 5 RepliesI'm using ListView control, with SmallIcons style in VB.NET. Icons are loaded fine, but when I start to scroll ListView down or up from scrollbar (clicking from arrows), rowheight drops to about half from normal in next 20-30 rows below/above upper/bottom row (depends from the scrolling position). After 1-2 seconds, ListView is "refreshed" and scrolling continues normally. When focus in on the ListView and I'm moving up/down with arrow keys or PageUp/PageDown, everything is normal. Any suggestions, what is happening? SmallIcons size is 16 * 16. Is it compulsory to set "Blank icon" with SmallIcon size to all rows, when adding them or what? Wasn't like that in VB6, how is it in VB.NET?
View 4 RepliesI have a vb-2008 program that contains a (listview) control.
View = details
AllowColumnReorder = true
Lets say the table has 3 columns (a,b,c) and 1 row of data.
a b c
1 2 3
I want the user to be able to re-arrange the columns (by dragging the column headers) before printing the contents of the table.
c a b
3 1 2
Statements like:
.. ListViewX.Columns(2).Text
.. ListViewX.Columns.Item(2).Text
.. ListViewX.Items(0).SubItems(2).ToString
Give the column-name (c) and cell-contents (3) of the origional table .. not the (3rd) column (b) of the re-arranged table.
How can i get the column-name and cell-contents of the (3rd) column of the re-arranged table?
Do I really have to go through all this just to find out what item has been selected in a ListView?

i am developing a point of sales system. currently i have my product code scanned and displayed in a listview. lets say that i have 5 product codes displayed in my first listview. By clicking on a button, how can i use these codes to call upon the details (prices, product name, etc.) of the corresponding codes and display in another listview?
i am using Visual Basic 2008 and MsAccess as my database. who have the idea on solving my question. (As my last thread has not been answered at all..
Here's the weird problem I am trying to solve but cannot get my mind around it. In a text box 1, the user enters 2 or more strings separated by comma. then in text box 2, the user enter 1 or more strings separated by comma. The output then puts the strings from text box 2 between the strings in text box 1
Example:
TextBox1 = visual basic, java, perl
TextBox2 = is better, compared to
