I really need line with this I can't figure this out . I am looping through items in a list view box, I am then adding them to a string. I need each new line in the listview box to be a new line in the string. I will then add this string an access database.But I can't get it to skip a line in the string
This is the code For Each lvItem As ListViewItem In lstVParts.Items

I've already used arrays and a random number to generate a sentence with the pattern KLAC, but I need to write this to a text document and then do it again. I have succeeded to write the first sentence, but the second will not register.This represents essentially everything I've tried. (I haven't included the arrays because they're pretty long.)
repeat:
Dim rndNo As New Random()
Dim chosen_aword = aword(rndNo.Next(0, aword.Length))

In button1 Keyup I want to be able to make textbox1 skip a line.How would i do this. I tryed
Private Sub button1_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles button1.KeyUp
If e.KeyCode = Keys.Enter Then
textbox1.text = vbnewline
End If
End Sub
I would also want to know how to make it when I push the button2 it will undo the letter I just did
Private Sub button2_KeyUp(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyEventArgs) Handles button2.KeyUp
If e.KeyCode = Keys.Back Then
textbox1.undo 'this will just undo the whole text I just did
End If
End Sub
There is a program that reads an Excel file using OLEDB and converts it to a tab delimited text file. This loop handles the conversion.
While reader.Read
Dim count As Integer = 0
Try
While (True)
temp = reader(count).ToString + ControlChars.Tab
output_file.Write(temp)
count += 1
End While
Catch ex As Exception
output_file.WriteLine()
End Try
End While
Not the most elegant code for sure, but it reads in each cell one by one, then throws an exception at the end of the row to write a newline. The only problem is that it skips the first line of the Excel document.

I have an application in VB.NET which gets string data from the database. This string has data which looks as below:
"This is the update: I have an issue with the application"
I need only part of the data, that comes after the new line i.e. "I have an issue with the application".
For this I am trying to search the position using InStr where the string has data in a new line. I tried many options, but they don't work.
I used "vbCrLf", Chr(13), "
", "
", "<br/>", Environment.NewLine, but none of them work.
How can I get the data I need?

I have a WinForms app with a multi-line textbox. This displays and retains (after loading from the DB) line break characters fine. However if I assign the TextBox.Text value to a string variable and then re-assign the variable back to the TextBox.Text property, the line break characters are lost and replaced with a square character (can't past them here as they just paste as a line break!)

I checked what string it is outputting and this is what it is giving: url...It is missing the Id content.
View 12 RepliesThe code below works for the class that I hard coded "XCCustomers" in my RetrieveIDandName method where I use CType. However, I would like to be able to pass in various classes and property names to get the integer and string LIST returned. For example, in my code below, I would like to also pass in "XCEmployees" to my RetrieveIDandName method. I feel so close... I was hoping someone knew how to use CType where I can pass in the class name as a string variable.
Note, all the other examples I have seen and tried fail because we are using Option Strict On which disallows late binding. That is why I need to use CType.I also studied the "Activator.CreateInstance" code examples to try to get the class reference instance by string name but I was unable to get CType to work with that.When I use obj.GetType.Name or obj.GetType.FullName in place of the "XCCustomers" in CType(obj, XCCustomers)(i)I get the error "Type 'obj.GetType.Name' is not defined" or "Type 'obj.GetType.FullName' is not defined"

I have googled this but all it comes up with is some C# and how to read a file line by line which is not what I want, what do you have to use to do this I tried this loop:
for each line in str
msgbox (line)
next
but it does not work, how do I get this to work?
For example I have a strint containing text with more than 1 line. For example:
"Hello How Are You"
I want to read a specific line of the string, if I choose to read line 1 of the string in a messagebox then the word "How" will probably pop up.

Trying to read in three variables per line from a text file that looks similar to the first code segment. What we've been taught so far to read in is something similar to the second segment. And it works all and good for single words per line.
If this was C++ I'm pretty sure I could getline and use the comma as a terminator, but I'm not sure if a similar function exists for VB.
