View 1 RepliesI have a list of files and all of them have a different size. I need to upload them in chunks of 250Kb (or less if it's a small file or if it's the last chunk of a file).What I would like to do is read a bunch of chunks (lets say 15 chunks), in a separate thread, and then store the chunks of data in some sort of list. This list must be available to other threads.
An upload thread (I don't need help with uploading itself) takes the first chunk from the list and marks the chunk as "currently being uploaded". When the chunk has been fully uploaded, then the chunk is removed from the list. A second upload thread takes the next available chunk in the list that has not been set to "currently being uploaded", etc. There are a total of 10 upload threads working at the same time.
As soon as a chunk is removed from the list, then a new chunk of data is read and added to the list.Does anybody know what kind of list I need or how I should do something like this? I don't expect people to write out the code for me, but I have no idea where to start with this.
I am using VB 2008 and wonder if there is a way to draw lines between the data elements in two listviews to bind the elements together?
View 1 RepliesI have the following "contact" data (exampled below) stored in an xml file.I've created a frmContacts windows form and placed a list box control inside it.I'm new to the list box but plan to have the users manage the list by letting them add, delete, and pick from it. For searching there should also be a sort function/button (by last name then first name).If the user deletes from the list the corresponding data in the file will be deleted.If the user picks from or adds to the list, I'd like to find the best way to populate the corresponding data elements on another form (i.e., in their respective text boxes). This will include the ability to edit/save from this other form too.

number = 4
length = 7

What I am trying to do may be better for use with SQL Server but I have seen many applications in the past that simply work on text files and I am wanting to try to imitate the same behaviour that those applications follow. I have a list of URL's in a text file. This is simple enough to open and read line by line, but how can I store additional data from the file and query the data?
E.g.
Text File:
link1 - 0
link2 - 0
link3 - 1
link4 - 0
link5 - 1
Then I will read the data with:
Private Sub ButtonX2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles ButtonX2.Click
OpenFileDialog1.Filter = "*txt Text Files|*.txt"
If OpenFileDialog1.ShowDialog() = DialogResult.OK Then
Dim AllText As String = My.Computer.FileSystem.ReadAllText(OpenFileDialog1.FileName)
Dim Lines() = Split(AllText, vbCrLf)
[Code] .....
Am I going completely the wrong way about storing the data after importing from a text file?
I just wondering if Visual Basic.NET and VB6 can do these examples.I have use python before and i will take some examples.Save numbers to a list and add
Quote:
this_is_a_list=[1,2,35,4564,532,2454,3404,3,455,2,1]
x = len(this_is_a_list)
this_is_a_list.insert(10, x)
len is a function who count how long a list is. This list is 11 numbers long. I will now insert/add number 10 after the last number. The first number has the place 0. The second number has the place 1.Can VB.net do that? Check how long a list is?Delete a list?

In .NET which data type do you use to store list of strings ?Currently I'm using List(Of String) because it's easier than Array to manage and add/remove stuff. I'm trying to understand what are the other options, when they become handy and when I should avoid List(Of String) usage.
View 4 RepliesSo I have a dropdown setup on the page called ddlVehicleType that is populated from a store. This method gets called when another dropdown is changed, and it's supposed to remove all items from the aforementioned store, re-add them as needed, and then populate the dropdown with the new values.
It's doing everything it's supposed to EXCEPT clearing the store before it re-adds the values, so the result is, when I switch, I'm getting what it used to be PLUS the new values that should be in there by themselves.[code]...

View 1 RepliesThis is probably a really basic question - but I have a list of items (custom objects) being passed from one winform (.net 3.5) to another. I want to create a local list to store changes that only get persisted if the user clicks save. Currently if the user clicks cancel - the changes are still applied in the first form because I assume the objects are reference type.I have the save working as it calls a service layer to do the save and then refreshes the other form - but not the cancel.

I have a feeling it is an easy one, but for the life of me i cant figure it out. My project at the moment is to grab content from a website and use it in some way (havent worked out this part yet, still trying to get the data).
Currently, i have grabbed the whole website and written it to a text file.. No dramas there. Then i read each line until i find a certain string... Again, no dramas. MY problem is; after reading and finding the certain string, i want the program to grab whatever "characters" there are until it reads a certain string again, and then put those characters into a string for later use.
so for example:

I got a list of objects. Each object has a property called Z (integer).There will come a point during run-time I will want to re-arrange such objects in my list depending on their Z property. The objects with lower Z go first in the list, and the ones with higher will go last.I have thought of a couple things, like making a new List, then loop through each object in the original list as many times as the amount of objects such list has (so if it has 10 objects, I would loop 100 times), and each iteration will check the Z values. When a cycle is done (for every 10 iterations), I will remove the object with the lowest Z number in cycle and add it to the new List. And so on until the 100 iterations are done.
