View 1 RepliesI am working on some project where I suppose to pull data from internet and print them out. Thing is I need to go to several different websites, so I want to make application that will go to websites declared in code and on those websites type into textbox word that I want and hit search. Once I do that I will easily use regular expressions to get information I need, but I need VB.NET application to do this. Example: I have button and textbox in my application. In textbox I write "VB.NET", once I hit button application will go to google.com and in search textbox type "VB.NET" and hit search and then I will pull data using regex into my application.

View 5 RepliesI have a file search that I want the user to select the folder they are searching the file in. At the moment I have
If Check.Text = "Correct" Then
If My.Computer.FileSystem.FileExists("C:Systemsfile.txt") Then
1CheckBox.Checked() = True
Else
1CheckBox.Checked = False
End If
However this check will be used for various files and its not usable if the FileExists directory stays the same ie searching the same folder and file for different records. I have a FolderBrowseDialog that I want the user to select the folder first in where to search and then within this chosen folder the static file will be checked. I have this as my folderbrowsedialog:
Dim Browser As New FolderBrowserDialog
Browser.Description = "Please select ."
Browser.ShowNewFolderButton = False
Browser.RootFolder = "c:"
Browser.SelectedPath = "c:windows"
If Browser.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.text.Text = Browser.SelectedPath
End If
I tried adding in this code to the actual file check to encoporated the dynamic folder search but its bringing up errors and not working, I have this:
Dim path As String = "Browser"
Dim f As ReadOnlyCollection(Of String) = My.Computer.FileSystem.GetFiles("test.xlsx")
If My.Computer.FileSystem.FileExists("test.xlsx") Then
Box.Checked() = True
Some tips and exsample for searching in listbox.
View 10 Repliesif it is possible for me to go to the specified listbox item via searching. Example;
Listbox1 items are
Apple
Banana
Guava
Pineapple
Peach
When I key in the word Apple in a textbox, the SelectedItem would go to Apple,
I have a listbox, and its like this:
13
45
sdfg
34
13
And a button, which I want to search if the listbox has atleast 2 same value's [13 , 13], and delete it. So It will be:
13
45
sdfg
35
i want to select all items from listbox1 and then use that items for searching.if it finds the items, it will be displayed on listbox2 and if not, it will be displayed on listbox3.give a simple code for this? i am thinking of making listbox1 items into string so that it would be more easy for searching.
View 11 RepliesI have a listbox with multiple items:
Quote:
The Sopranos (Season 5) Boxset (DVD)
Braveheart (DVD)
MTV The City - Complete Second Season 2 (DVD)
I have a TextBox where a user enters a search:
The Sopranos Season 5 Since ListBox.FindString() wants a String and not a RegEx, I can't use a Regular Expression. (right?) So, if TextBox.Text = "The Sopranos Season 5", then ListBox.FindString(TextBox.Text) will not find my entry with "The Sopranos (Season 5) Boxset (DVD)".
Right now im using
If ListBox1.FindStringExact(TextBox2.Text) = "0" Then
Label2.Text = "yes"
GoTo procheck
[Code]....
and it searches the first item in the listbox correctly but nothing else. Im assuming im going to need to loop through the listbox somehow?
I have a code to search through a listbox with mutiple search criteria. Here is the code:[code]When I search for something, how do I make sure I do not obtain 2 of the same results, If both criteria are found, or if all three are found?
View 4 Repliesi have this code [code]i want it to return me only 1 value which is the exact text as textbox1.text.
View 1 Repliesi have this code
vb
For Each sWord As String In listbox1.Items
If textbox1.text.Contains(sWord) Then
but the problem is if the textbox1.text value is ( new text ) and the list box have like 3 items
new
new text
text
it will return me 3 values i want it to return me only 1 value which is the exact text as textbox1.text ( new text )
I know the sort of a thread is already here, but I have a different question. I have ListBox1 and TextBox1 and the Items of ListBox1 are:California
Chicago Washington and as I start typing the text into the TextBox1 (TextBox1_TextChanged), then it will select the first Item in ListBox1,that is closest to the text in TextBox1:
For example:
If I type "A" to the TextBox1, it will select California (California)
If I type "C" to the TextBox1, it will select again California (California)
If I type "CH" to the TextBox1, it will select the Chicago (Chicago)
AND!!! If I type "SH" to the TextBox1, it will select the Washington (Washington)
so it won't only search the first letters, but it will even search the letters in the middle of the text, too.
I will include a link to a copy of my source Code. The Problem is that I have to create a user management system. I have almost all my features working but there are one or two I can't get working. When the program loads a text file is read and the program lists the first name of everyone in the text file into a list box. I want to be able to get so that when you click a name in the list box, the persons information will be displayed in the text boxes to the left. And also when you edit those text boxes you can click the button for modify current and it will modify that persons data. The other problem I'm having is being able to search that text file for the users e-mail and return the first names of people who have that e-mail into the listbox.

I have a code to search for specified text in all listbox items. Here it is:
ListBox2.Items.Clear()
For Each item In ListBox1.Items
If item.ToString.Contains(TextBoxDropDown1.Text) Then
[code]....
This works fine. But if I have search for this:
"My Search"
I wont find this:
My sEarCh"
Is there any way to search for text of any casing, and if so how can I adapt my code to do this.
I have a listbox with a directories contents in it, I want to be able to open the folder in the listbox and also have navigation.I have noticed that if you set the web browser url to a directory it will do that automatically
