VS 2010 Listbox Data Extract After Entry & Sorting?
Sep 26, 2011
I have an application that receives data input from an automated set of devices. This data stream I have managed to capture & get it into a list box which I can sort based on the Device ID & the time that the response was received.There is a set time window for the devices to transmit their data into the application and during this each device is not limited to the number of responses it can send (ie :- Device 1 can send in 2 responses where Device 3 can send in 40 responses, etc).All of the responses are captured, listed & sorted within the listbox (this bit is working ).I now need to extract the last (ie:- latest) entry in the listbox for each Device ID & this is where I am stuck. I can retrieve the last item in the list but cant seem to extract the last item for each Device ID.The code that I am using for the Device response capture, etc is :-
*********Code Start
Private Sub btnPoll_Click(ByVal sender As System.Object, ByVal e As_ System.EventArgs) Handles btnPoll.Click
[code].....

I've been testing an application I'm working on in Windows 7, Vista and XP. If I'm using XP then I get a couple of solid black blocks after the items listed in the ListBox. They are absent when running the same application in Vista or 7. I have the enable application framework checkbox unchecked. I haven't tried changing that to see if it makes a difference.

The DB's on the Hard drive are contained in folders with a naming format as follows (Jan94 - Dec08)The issue is that on the HD all the folders(yrs) for Apr are listed together and then the rest listed the same way, just sorted based on 1st alpha character. The format I want to show in the list box is as follows:

I'm updating a program that was written in an older version of VB (by someone else) and I can't figure out to how replicate this data entry line in my Form.
Each textbox can be changed and there is a nice scroll bar at the bottom to move left and right as you enter each datapoint.
I tried using multiple tabs within a Panel and setting the Appearance to FlatButtons, but the text area under each tab gets covered when you select another tab.

I have data in a DataSet and want to extract 3 fields from each row in the DataSet.
Field1 = String
Field2 = Date
Field3 = Time
I then want to add all the Field1 strings to a combo list box, sorted by the dates and times in Field2 and Field3.
Is there an easy way to get the data from the DataSet in a Sorted order?
i.e. Equivalant to saying "SELECT [Field1] From [Table] ORDER BY [Field2], [Field3]" in SQL.

I have a reporting utility for my users to view, send (via email), export SSRS reports. I have set up date parameter boxes with calendar drop down and they are able to send via email a URL link that would either display the report via ReportViewer or send a link via email (listbox of email addresses) that would let them view the report in Excel or PDF. This is working just fine. Now I just added a button for adding new email addresses and a new windows form with a textbox for entering the email address and a command button for Save Email Address. I am able to save the email address just fine from the small pop-up window for entering the email addresses but after closing the window, the listbox of email addresses on the main form does not get refreshed with the new entry from the textox even though the SQL table EmailAdresses got updated.[code]...

i have 1 button, 1 listbox and 1 textbox.this is my code
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
ListBox1.Items.Clear()
Dim finish As Integer = TextBox1.Text
[code]....
if i set the sorted property of listbox1 to true that code will add 0 before the inputted number so that the sorted property in listbox1 will be usefull in sorting integers.
for example i have 1,15,30,36
it will make 001,015,030,036
thats what i think am not sure because i cant edit the code so that it will work in my program.

I need to sort the items in a visual basic listbox numerically, that is, I have a collection of numbers I would like to be sorted increasingly.
I tried to simply use the listbox's Sorted property, but found that it treated the numbers as if they were strings, that is, it would look at the first digit, then the second, etc. to determine the order. That meant that 13 would show before 5, for example.
I thought of dumping all the numbers into an array, soring the array, and then pushing them back to the listbox, but, honestly, I don't know how to go about the sorting. I figured the array would be useless, since the listbox already acts as a pseudo array.

I am trying to sort text (File name and path), by having a listbox with just file name and and a datagridview with two columns filename and path.
The listbox sorts it differently from the datagridview. Mainly this is where there is a ' ie listbox puts "you're" before "you are" where the datagridview puts "you are" before "you're".
I thought I would just sort using datagridview and then read from datagrid and add to a non sorting listbox, but this did not work although the datagridview shows sorted, when you go through and a loop, reading each row to add to listbox they end up the same order they where originally put into the datagridview befrore sorting.
What I want is a sorted list of file names only, which will be obtained from several folders and then when clicked with be able to extract the complete path and filename.
I have code with a listbox and datagridview which works ok if I remove any files with ' in them.

I have a listbox that prints 2 different values each line. The first one is String and the second one is an Integer, (although I've converted it to String). How do I extract the first String value? One is suposed to be able to mark one line, and remove the selected lines values from 2 different arrays, and for that I need the String value.

Currently we are using a VB script macro created in word to create some fairly simple forms based off of data entered on a data entry form. I am very new to VB, and I have been able to create many applications using forms, but I have absolutely no history creating reports. I have been reading up on the reports, and it looks like they are designed to use with data sources like tables. I merely want to take either data from the entry form, or from data derived internaly from processing the user entered data and populate a defined report "form". I have been searching, but there is so much on printing reports, that I feel overwhelmed. I am not looking for the exact answer as much as a link or place to look for a sample for what I want to do.

I want to transfer my data from one list box to an other and save the data and display it at the same time with the TIME, Name, and the Quantity. For example, if I have a movie ticket, and says I bought one ticket thats 10 dollars. If I did type all the calculations with tax it should be 10.10 for the 10% tax. This will show on first of my list box. Secondly if I press something like Enter, it will show that 10.10 number and also put it in the other lstbox. I have 3 list box. One to show the current transaction, one to show the history of them and the total amount of all transaction.

CODE:
That code works to read the entry data and to recognise the correct data, and the incorrect. However, even if entry is correct, the error msgbox will appear (x times of how many records there are in file), despite being navigated to the menu. Anyway that the Else isn't triggered when data is correct. Also for it to appear just one instead of (x times of how many records there are in file.)

Basically, our users enter values onto a spreadsheet and I have been asked make the spreadsheet output to a CSV file preferably each one completed appears as a single line in the CSV.Upon examining the spreadsheet, I cannot figure out the best way of acheiving this, or if it is easily acheivable in the first place.I have attached an example of the spreadsheet data, to give it some context the spreadsheet records times that carers have visited a client, which can happen many times a day over many days per week, there is also a yes/no for each day on the sleepin.
