Script Store Not Removing All Elements Before Re-adding
Oct 7, 2010
So 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]...
I have a large one dimensional array that is called ArrayHold which is populated at runtime. I run a loop to scan through the array to find out which elements need to be removed based on a few parameters. This all works great, now I am left with two arrays. The original one and a new one which contains the locations of the elements to be removed.
Original Array: ("A")("B")("C")("D")("E")("F")("G")("H")
Second Array with index/count of elements that needs to be removed: ("0")("3")("5")("7")
End result should be preferably not in a new array but a "ReDim" of the original array:("B")("C")("E")("G")
What would be the simplest way to achieve this? I could run a loop to make all the elements that need to be removed "0" or ""? Would there be an easy way of resizing and array by dropping/removing all the white space or empty elements?
I have a string with xml data.Dim appManifest As String = New System.IO.StreamReader(Application.GetResourceStream(New System.Windows.Resources.StreamResourceInfo(e.Result, Nothing), New Uri("AppManifest.xaml", UriKind.Relative)).Stream).ReadToEnd()
I am just starting VB at 60 years old and with no programming experience and nobody to ask for help...except here, of course. So needless to say I am hitting brickwalls. I am using "Murach's Visual Basic 2008" and it seems to be a good book. This is what I am up to I have to declare an array with 5 elements with an index. I think that part is OK. Then add code that adds each element to the next one every time a user clicks a button. I have had many tries but the best I can get is just the grand total of the elements. Here is the code I came up with:-
[Code]...
Is anyone able to show me how the button click would reveal a progressive total of the elements each time a user clicked on it? It would be good if the book came with answers or had a forum for their readers.
I have an array x in size of objects (between 1 and 100) and I want to increase the size to 101 ... I've resized the array and that adds the objects but unfortunatly (not suprising) the added items have not been initialised, do I've reverted to using a do while loop and adding the elements indiviually, but looking at the code around it where addrange is used extensivily, I was just wondering if that was a neat vb.net way of doing the same thing
Bit of a learning question, just looking for neat ways to do the same thing
I am trying to add (Push) whatever the user enters in (MyStack) into 5 different labels that should show the (UserResponse). The problem is I don't know how to display each element in a different label. For example:
- The first element that the user enters (UserResponse) should be in Label1
- The second element that the user enters (UserResponse) should be in Label2 etc.... up to label5.
Also, when I press (Pop) the elements should disappear (Last in first out).
Public Class Form1 Private MyStack As New Stack(4) Private Sub ButtonPush_Click(sender As System.Object, e As System.EventArgs) Handles ButtonPush.Click
I have a data table in a loop that adds rows on each loop. During the loop i collect an array of unknown size. At the end of the loop i want to add a new row to the datatable with eachelement of the array as a field.[code]I could hard code this if i knew how many item would be in the array but i dont.Is there any way i can loop through the array and append the value to a row?
I am looking to create an application which includes: Removing a computer from the domain Removing a computer from a workgroup Adding a computer to a workgroup Adding a computer to a domain This application will be ran on the computer manually.
I am working with my project and I have difficulties in my program. This is the set-up: I put a textbox1 and a button1 in the form, textbox1 is for the property of the label text to be add when I click the button1 I have another textbox, label and a button,I want the added button to remove the textbox, label and if possible the button itself, is there a way to delete a control by the added button?
i'm creating a web form and i want a user to be able to make certain selections and then add the selections to a text box or listbox.Basically i want them to be able to type someone name in a text box ... check some check boxes and for it up date either a text for or a list box with the result on button click...
I'm trying to use a split button from a tool strip to add and remove selected items in a listview.Users click the button to add the selected item which appears in the split button drop down menu as checked.The drop down menu has three items at any one time, each with a default value of <none> - this is replaced with the text from the listview when an item is added.When users click the item from the drop down, the item is unchecked and the text returns to <none>.
The drop down should populate from the top down so if a user removes item 1 or 2, the items below would appear to be moved up with the 3rd item now showing <none>.
I am trying (Push)add data into my stack (length of five) and (Pop)delete from the end of my stack.
I need to know how can:
- Add the elements to the stack with keeping track of adding and deleting from it (adding an element will increment until 5 and deleting would decrement until the stack is empty).
Private Sub Button1Push_Click(sender As System.Object, e As System.EventArgs) Handles Button1Push.Click Dim Stack(4) As String
I am trying to learn how to work with the different controls in Visual Studio for VB.Net in particular the List View and Tree Views. I don't have any code to show as I am not working on anything in particular just messing around with it to learn what the different controls do that weren't covered in my Intro to VB.Net class last semester.I would like a clearer explanation on how to actually use code for these controls. In particular adding and removing items from the List and Tree Views using code.
The user picks x amount of scenarios from the combobox, and x amount of columns appear in the datagridview. If the user changes the number of columns from x amount to y amount, the columns should be added/removed respectively but currently when y amount is chosen x amount of columns are in the datagridview.
I'm not sure how to do this, I've tried using an IF statement under the .SelectedIndexChanged event but the code adds columns until it reaches as high as it can go, then pulls an error saying too many columns.
i'm making a small word processor program using vb 2008 and i need the codes for the following commands: creating table adding and removing rows and columns header and footer
I'm have a question about an online store using Visual Basic but I would like to add a screenshot here in the forum so the users can easily understand what I am trying to do. Is that possible?
I need to read an xml document from a database record into an XDocument object in order for it to be deserialized. So that the deserialization will work, I need to apply a specific namespace to each of the level 1 elements. So XML looks a bit like this:
[Code]...
How do I prevent the blank/empty namespace being added to each child element of the element to which the required namespace has been applied?
I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.
So far I have this --
Public Class Form1
Private Sub Button2_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button2.Click Me.Close() End Sub
I created a method and pass the element type, id, and any inner text that instantiates a new html element. The last statement: Me.Controls.Add(element) adds it to the end of the page, but I would like it to be inserted in a specific position (between 2 divs within a form). What I am describing is very similar to this post on SO here, although it was for javascript.
i know that integer is a variable to store whole numbers and that a string is a varialbe used to store any text, but what variable type would you use to store a number that has decimals?
"Create a class called Invoice that a hardware store might use to represent an invoice for an item sold at the store. An Invoice should include four pieces of information as instance variables--a part number (type String), a part description (type String), a quantity of the item being purchased (type Integer) and a price per item (Type Integer). Your class should have a constructor that initialize for each of the four instance variables. Provide a property for each instance variable. If the quantity is not positive it should be set to zero. If the price per item is not positive it should be set to zero."
I attached the code I have. obj is underlined and says "Argument not specified for parameter 'Invoice4' of the 'Public Sub New (Invoice1 As Object, Invoice2 As Object, Invoice3 As Object, Invoice4 As Object)' and so the program won't run. What am I doing wrong?
Public Class Form1
Private Sub TextBox1_TextChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Dim obj1 As New Invoice(Val(TextBox1.Text)) TextBox1.Text &= obj1.Invoice1 & vbNewLine TextBox1.Text &= obj1.Invoice2 & vbNewLine TextBox1.Text &= obj1.Invoice3 & vbNewLine TextBox1.Text &= obj1.Invoice4 & vbNewLine
I am trying to create a simple Word doc that when the user presses the button it takes the information in the boxes and tosses it into a template style paragraph. But my issue is that I have two combo list boxes as seen in the picture. I want to have two values in the drop down list as seen in the labels next to them but for the life of me I can't figure out how to do this in Word 2007. In Visual Studio this is much easier but I am work and need to snap this out for the folks at work. Is there an option that I can choose in the properties where I type in the values for each drop down or do I have to add them in at run time?
I'm adding labels at runtime to my form with a tag. Let's say I have 3 labels with the tags, "1", "2" and "3". I'm adding the tags by counting the labels + 1. When I remove a label with tag "2" from the form there are only 2 left. When I add a new label it will add a new tag "3", but that one already exist. So my "solution" isn't a very good one Although tag "2" is free, I want to give it "4". Any thoughts on how to code this properly?
i would like to get the unique catlogs, so from this list i want to extract only 7190, 7192, and 7193. i have a script that puts it into a dropdownlist by using:
DropDownList1.DataSource = dv DropDownList1.DataBind()
