I'm trying to split an inputted string (txtStart.text) into separate integers. The split function works fine for me, but I can't figure out how to store the each part of the array... This is my current code that I based on an example from MSDN library:
Private Sub btnGo_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnGo.Click
SplitStringIntoWords()
End Sub[code]......
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 RepliesThis should be fairly easy, yet I have no idea on how to approach this. Perhaps the split command . Anyway, what I need to do is split as string into two integers.
For example MyStringXS = "10, 20"
I need to end up with:
MyIntegerX = 10
MyIntegerY = 20
BUT!
These strings obviously change. So it could be MyStringXS = "120, 230" Or MyStringXS = "12340, 20342" And so on.
I suspect there is something wrong in my application, specifically in a part where I have to compare a couple strings and a couple integers.
I do something like this:
If myString = myOtherString Then
do something
End If
And the same thing for integers.
However, for some reason, it is not returning true... also, I heard somewhere there were more proper ways to compare strings and integers.
if i have 2 textboxes and i want to do subtraction with textbox1 and textbox2.
The value inside textbox1 is "5 12 30 8 2"
The value inside textbox2 is "7 9 14 8 3"
May i know what can i do so that the result will be "-2 3 16 0 -1"???

i have a form with 12 text boxes. I'm trying to get the data from those text boxes to "save", and when that form is opened again have the data be inserted back. This form has different time slots so I need to be able to have it save and repopulate based on what time slot I am clicking on. I was going to have it read the data by splitting it with commas, then inserting them back into the correct fields but it's not working. I had it write the results to a text file and they get written correctly and inserted back, but the problem with that is it only reads that text file so every time slot I open up gets the same data. Below is code I used to get the data when the Save button is clicked. [Code]
Problem is I get an error saying "Char values cannot be converted to Integers" on the first line, the (","c) part. Plus even then I don't know if this would do what I want. EDIT: Ok I fixed the error and got it kind of working, but now I have a new question. Now, I put a button on the form that I can use to load the data when I choose to just to test. This works, it takes the data from each time slot and loads it back when I click the button. New question is how can I get it to load as soon as I open the existing appointment? Putting it in the form load event won't work because it checks for data before there is any in there.
Originally i wanted to ask if it's faster to sort Integers than Strings.But i have answered this question myself and i'm suprised of the big difference.Why is sorting and BinarySearch Integers as much faster compared to Strings?
The (VB.Net) Test with 1.000.000 Int32/Strings:
Private Function CheckIntBinarySearch() As TimeSpan
Dim watch As New System.Diagnostics.Stopwatch()
Dim rnd As New Random(Date.Now.Millisecond)
Dim intCol1 As New List(Of Int32)
[code]....
Consider having large collections of "String-Integers"("1","2","3",...). Would it even be better to parse them to integers before sorting and searching them? What is the cost of parsing Strings to integers?
I am using an oleDb connection to connect to an excel spreadsheet (.xlsx) file and load the information into a datagridview. From there I hope to have it edited by a person and programmatically at runtime. However, I noticed that when I import a file that has integers in a column, it will not import any of the string values in that column. Also, It will not allow me to manually enter strings into that column at runtime - it results in an error stating: [Code]

I have a "if This > That then" statement, that doesn't seem to work, as it triggers regardless that "This" is smaller than "that". Does it matter that these variables are marked as strings vs integers?

I am uploading files to a directory and I am also just getting the file itself not the directory and the folders.

What I want to do is separate out the 6122002, the Abstract, and the date which is 9-11-07 so I can insert it into a sql database.

how to convert an array of strings to an array of integers? I want to convert a string array with 77, all string numbers, to an integer array?

View 6 RepliesBasically I have and array of integers that vary in size. I need to compare each number to each other number and display which number is repeated. For example:
Dim ints() As Integer = {1,2,2,5,4,6}
The number that shows up more than once is 2.
How can I run through the array and compare each integer with the numbers in the array. I tried a for loop but it didn't return the value I was looking for.
I have string which is:
document1.txtdocument2.txtdocument3.txt
What I would like to do is split it so it shows in a listbox as
document1.txt
document2.txt
document3.txt
I have come up with a solution which may work. Its preety over complicated too me but this is the only way I could think of?
What I need help on is a code so that after every ".txt" it will place a "/" so the string will look like this:
document1.txt/document2.txt/document3.txt/
Then I would use this code to split the string:
Dim I3() As String
I3 = I.Split("/")
For g = 0 To I3.Length - 1
ListBox1.Items.Add(I3(g))
Next
dim text as string One:This:Is:A:Test
Dim arrsplit() As String = Split(text, ":")
textbox1.text = arrsplit(1)

View 5 RepliesI would like to create a split container with a three way split. The first split is a vertical split. The second is creating a horizontal split within panel2 of the first split container. panel1 will hold a treeview control the other two panels will hold listview controls
I think this question has been asked already in a couple different ways and I've reviewed those posts and I've tried to do what was suggested but it doesn't seem to work for me. I've tried to place a second split container inside panel2 of the first split containter. This gave me what appeared to be a three way vertical split.
I 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?
