View 11 RepliesMy professor recommended that I must create a hotkeys for page by page browsing for my Todo-List. I need to create a hotkeys because my Todo-List application is different from other todo-list application. Because it only display the entries and there is no buttons display on my application. I need hotkeys not a shortcut keys because it must change the pages even if my todo-list application is minimize or other program is being use(TodoList Application is Running). I want to have a PageUp Hotkey for the next page browsing and PageDown Hotkey for previous browsing.

View 6 RepliesI am working on a realtime application where the data is addded to a List(of T) all the time. MB per minute
Elements older than X minutes shall be removed from the beginning of the list to free memory.
As far as i can understand will there be an internal (slow) redim when i add each element after i have reach the number defined with the Capasity metod. (I set that quite big from the start, but the data speed is unpredictable so it can be exceed)
What happens each time i remove and element from the beginning of the list , seems like it takes a lot of time, ? new redim ?
What is the most CPU fficient way of removing 1 or many elements from the beginning of such a list?

lstListView is just a standard lstbox. Have no idea why this is happening or how to fix it. I can post the rest of the code if needed.
I've searched and searched for an answer to my question, but as of yet, have yet to find a solution to what I'm looking for. My background - 6 months out of College (Computer Studies)
Right now I'm working on a program that is going to be used to handle database information (Access 2007). On the main form the user can select 3 pieces of required info from drop down list boxes. Those are required. Then after that they are able to enter a first name and a second name. They then add that name to a list box below. They can add as many names as they want to a list box. Then from there they have the option to either just save the info, or if required (which will more then likely be the main option) print each person in the list their own certificate. I have designed a separate form laid out the way required for the certificate.
The trouble that I'm having at this time is that I am unable to make the printing process show all of the certs that are going to print in a print preview. I have been able to get it to only show one. The form is set to load where hidden = true.
For a class project I am supposed to search through the attached file, and write to a new file the years between 1789 and 2009 that are not present in the fifth field. What is my best bet for determining what years are not present?

Should I make an array of integer between 1789 and 2009, then search for every year in the file, then set a flag to false if not found; is there a simpler way to accomplish this using LINQ?
I'm using Report Viewer(VS 2008) to make a report in VB.net. I add Table with Table Header, Table Detail, and Table Footer. Then insert a Table Group(table1_group1) and add expression =IntRowNumber Nothing-1/10 on that group. I check page breaks at end.
When I load the report its show normal :
page 1 : page header+ table header + table detail(10 list data) + page footer
page 2 : page header+ table header + table detail(5 list data) + table footer + page footer
But when I click Print Layout Icon its show an extra page(page 3):
page 1 : page header+ table header + table detail(10 list data) + page footer
page 2 : page header+ table header + table detail(5 list data) + page footer
page 3 : page header + table footer + page footer ( this is the error)
I also try to print the report and its print 3 page.
I have a table being imported into my VB application that has 3 columns. I have written code to import the table, and have written code to display on the first column (country) in a list view.
What I want to do now is have the user select / highlight an item in the list view, and have the third column (currency) related to that selected country appear in a text box when a button is clicked.
Here's the code I've written that successfully imports the data and displays the first column:
Private Sub frmCountry_Load(ByVal sender As Object, ByVal e As System.EventArgs) Handles Me.Load
Dim dataCountry As New DataTable()
[Code]...
Should I perhaps use something other than a list view?
So I have a program that is supposed to support a small business. I have the work completed and the professor said it was correct but I wanted to go do a little extra.Basically, on the Order screen, you begin to type the name of a customer/supplier/employee into a text box and a list of names that fit the criteria pops up in a list box (lbMatchingAccounts). When you select it, you can hit enter new order and be transported to the Order Details screen to enter the new order.
What I wanted to do was to create a new list box (lbOrderId). What I want is to be able to select a person from lbMatchingAccounts and have all their Orders populate in lbOrderId.

Okay I'm making a song organizer and I have a program that will load the files in a folder into a box and display the songs info into a list view. That part works fine but when you click the button to make it do anything it will get the variables that it need from the tags on the cells for each song but for some reason the one for the Album just disappears... I tried having it just show the value in a message box and it works fine. Just when I try to combine it with another variable then it wont show at all. Heres my code
