I am trying to make a MVP kinda system and I am trying to define and load an array, through the system. Then read it out and it should populate a ListView1 object.I know they are set correct, because the console tells me it's set ok.I know the sample would fill with the same item (a week to be exact) every time i add an item, but that's not the point.Also, is it possible to define the array without the index, i mean now i set it with (6) so it sets 6 blocks for strings, but I would like to be more flexible. Is there a way like in php for example
I am trying to learn about arrays and the for next..loop. This is a noob question but I cant seem to get it to work. I am trying to load an array with 30 numbers that print to a list box.
Dim a(29) As Integer Dim strVar As String = "{0,-5}{1,5}{2,5){3,5}{4,5}" Dim x As Integer
[Code].....
For some reason I keep getting errors in the output statement that says "Input string was not in a correct format."
Okay, so I have been developing my own MP3 player recently, and now I thought I would make the player remember what songs were in the playlist when it shut down. It now remembers the playlist file that was used last, but I would still rather make it so that it remembers all the songs without saving the playlist.
I've been using a setting to save the playlist file, but when I try this:
...it doesn't work. The savedSongs is a System.Collections.ListArray. Heres the code at Form_Load I'm using at the moment.
Dim loadSongs As New System.Collections.ArrayList loadSongs = ExperimentalPlayer.My.Settings.savedSongs lbl_songname.Text = ""
[Code].....
Should I use some other kind of variable to save the filepaths? Well, the other option is that I use a text file for that, but I'd rather make it like this.
I have a program that will compare an array of grocery list items glist and an array of coupon item clist.When I compare the two and if there is a match somewhere in the array I want to have a picturebox visible.When there is no match, I want the picture box not to be visible. [code] The code seems to work great until I come to the else statement.When the code finds a match it displays the picture box and the msgbox without error, but as soon as the message box is cleared, even though i've input it as an ELSE statement, the picturebox goes false again.Does anyone have any idea of how I can "hold" the picturebox to stay visible while the match between the arrays exists?
i have issue returning a list in a web method. here is the code
<WebMethod()> _ Public Function getTags(para_parents As String) As List(Of getTypeDetailsByParentName_Result)() Dim context As New PPEntities
[code]....
the error is
Value of type 'System.Collections.Generic.List(Of SaftyonRoad.getTypeDetailsByParentName_Result)' cannot be converted to '1-dimensional array of System.Collections.Generic.List(Of SaftyonRoad.getTypeDetailsByParentName_Result)'
I am trying to get a count of all the times a byte sequences occurs in another byte sequences. It cannot however re-use a bytes if it already counted them. For example given the string let's assume the byte sequence was k.k it would then find only 3 occurrences rather than 5 because they would be broke down like: [k.k].[k.k].[k.k]. and not like [k.[k].[k].[k].[k].k] where they over lap and essentially just shift 2 to the right.
Ideally the idea is to get an idea how a compression dictionary or run time encoding might look. so the goal would be to get down to just 2 parts, as (k.k.k.) is the biggest and best symbol you can have.
I have a class called Car. Car has a bunch of properties i.e. Car.Color. CarService has a method called GetCars(). Within GetCar, I have a loop that appends a List of, you guessed it.. Cars.[code].....
I get: Value of type '1-dimensional array of Namespace.Car' cannot be converted to 'System.Collections.Generic.List(Of Namespace.Car)'. What would be the best way to convert this 1-dimensional array' back into a List of Cars?
what i want to do is load a list of urls (one per line)
for each url
then open that url in webbrowser
then write some lines to the console(console output on windows form)
then move on to the next url and repeat -- the code i have so far is
Private Sub Button6_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button6.Click Dim objReader As New StreamReader(TextBox2.Text) Dim sLine As String = ""[code].....
But it just loads the first url and seams to load the url after running the rest of the script because "Done" appears before the page is loaded.how could i get each url load and then move on to the next url..
I'm having some more trouble with working with arrays. My assignment is to take an input file of 10 numbers and display the original array, the array reversed (1st element is last element, etc.), the average of the parallel elements (nth element of both arrays), the average of the original array, and the elements greater than the average. I know I need to load the file into an array. However, I can't seem to figure out how to reverse it, nor average the two even if I can get it reversed.
I am trying to load an array from an excel sheet (in xml), whic I have managed by altering some code kindly provided by Beth Massi. the trouble is that I don't really understand some of the original code, hence I cannot remove the binding to some objects in the GUI that I don't need.

I accomplished the task of creating a picture viewer that finds pictures in a directory,adds them to a listbox, and displays them in a picturebox at intervals using a timer. Now, I am trying to achieve a similar task using an array in a continuous timer-display fashion so that after the last image the process starts over from the first image again

I've got a database with the fields: tuneName, Artist, Sales and yearIssued I'm trying the load up just the first field (tuneName) into a list box. I've managed to load the database into VB but I dont know the code to do this specific thing.Also I want to be able to select one of the items in the list box and the rest of the fields to appear in text boxes on the form.
I'm using this code to load a text file into list box.
r = New IO.StreamReader(str) While (r.Peek() > -1) ListBox1.Items.Add(r.ReadLine) End While r.Close()
But it loads the whole file into list box. I only want to load those lines of text that contain following number: 2008. It doesn't matter if the "2008" is at the beginning, middle or the end of a line.
