Create A List Of List In That Would Like To Work On Multiple Accounts At Same Time

Oct 24, 2011

i am trying to create a list of list in that i would like to work on multiple accounts at the same time. lets say i have 5 accounts. every account has a seperate name. each account has a few fields. so i though of having a list of bookkeeping (with 5 accounts) and a list of accounts (with expense, income, tax, status, etc as fields). [code] and if the idea of using list of list works how do i loop through both lists.

How To Create Multiple List (of String)

May 13, 2010

VB 2010 express. I have a situation where I want to create multiple list(of string), in a sub routine during run-time, where the list is available to other subs and functions in the same module, either to populate, edit or delete. The quantity of lists, names of the lists and their capacity will not be known until run-time. What would be the method and syntax for doing this?

Create A Toggle Button That Switches A List To A Range And Then Back To A List If Needed?

May 14, 2009

II am trying to create a toggle button that switches a list to a range and then back to a list if needed. I am able to get it to do both but when I add an item to the list, convert to a range and then convert back to a list it leaves off the last items I entered.I tried to work in a code to select all cells but I must not be putting it in the right place.This is what I have so far:

ActiveSheet.ListObjects.Add(xlSrcRange, Range("$A$3:$AE$7"), , xlYes).Name = _
"List1"

I realize the problem is the $AE$7 (the $A$3 is correct)

Create Local Copy Of A List To Be Able To Change Elements Only In New List?

Oct 26, 2011

This 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.

Create A Program Which Will Allow Users To Select Multiple Files From A List And Then Burn Them All To A Playable DVD?

Oct 24, 2011

I am trying to create a program which will allow users to select multiple files from a list and then burn them all to a playable DVD. It would be wonderful if i could setup a custom menu programatically as well. I have seen some documentation on Imapi 2.0 but i have not been able to find too much suppoert for it. I have also found a few SDK's out there but most are over $1000 which just isnt in the budget.

1) Is there a library included in windows 7 that will allow me to do this.

2) Is there an inexpensive or open source sdk with good documentation out there to do this with

List To Update Every Time And Show The Values Each Time To Which The Previous Value Is Added To The New Calculation?

Jun 22, 2010

The idea with this form is to add the futures which is calculated when the button is pushed but I need the list to update every time and show the values each time to which the previous value is added to the new calculation, e.g. of what it should look like in listbox:

Year 1: $1,290.93
Year 2: $2,724.32
Year 3: $4,350.76
etc....

I have been working on this a while and I am at a standstill, I was given a function to clear the form everytime it calculates but I don't know how to implement it, I am new to VB. Here is what I have so far:

Public Class frmFutureValue
Private Sub btnCalculate_Click(ByVal sender As System.Object, _
ByVal e As System.EventArgs) Handles btnCalculate.Click

Can't Get Listcount To Work Or List

May 14, 2009

i am trying to put the contents of a listbox into an array using listcount so i can sort and manipulate the data in the listbox using linq. Everytime I try to use list**** it errors and tells me that listcount is not a member of systems.windows.forms.listbox It also gives this error or list. Here is the for loop i am trying to use to put the data into the array.

[code]
For i = 0 To displayListBox1.Listcount - 1
sorting(i) = displayListBox1.list(i)
Next
[code]

i dim'd i as an integer and sorting() as a string early in the program as class level variables. displayListBox1 is the name of the listbx containing the data I need to use in my LINQ inquiry.

Any Way To Add Files To List Other Than One At Time?

Oct 8, 2009

I am building help files for a program using HTML Help Workshop.I have been trying to manually add files to the project file list as I write them, as HHW doesn't do so automatically.But it doesn't seem to matter whether the files are included in the list or not.When I compile, it tells me if any are duplicated, but it doesn't tell me if any are missing.(I have deliberately removed some to see if it makes a difference, so it's not that I haven't left any out.) And, whether they are in the list or not, the compiled help seems to find the files it needs.What is this list of files for?What files need to be included in it - html, css, images, maps? Why doesn't it seem to matter if my files are included in it or not? Is there any way to add files to the list other than one at a time? (e.g specify an entire folder?
