So we are just starting to learn about list boxes in vb1. In this program the user enters up to 10 scores and after each input (decInputScore) the total score so far has to be calculates (decTotalScore) and then of course when all the scores are entered, at the bottom the final score it calculated. (decFinalScore) (decFinal). I'm not exactly sure what I'm doing wrong, I can't get it to calculate the correct total scores after each input, and I'm getting 0 as the final score. Here is a visual of what the form should look like: the black square is (btnEnterScore) a pop up message box comes up in which the user enters each value when clicked.[code]

I am trying to write some Linq to SQL that will bring me back a list of rows containing a single instance of BaseQuestionIDs but I want the row with the highest version, so, from the following table of data:
Id CreatedDate Version BaseQuestionID
2 2009-10-07 13:47:27.687 1 2
3 2009-10-07 13:49:35.010 1 3
4 2009-10-09 16:03:45.973 1 5

I want to return:
Id CreatedDate Version BaseQuestionID
2 2009-10-07 13:47:27.687 1 2
3 2009-10-07 13:49:35.010 1 3

I am now trying to add a feature that was requested, mainly the ability to click a button or label, and have a messagebox pop up with the Vehicle with the HIGHEST total stats in the Vehicle list. What I need to know is:
1. If it's even possible to search for the highest total stat value in the Vehicle list?
2. If it IS possible, how difficult would it be?
[code] I've searched my a** off the past 2 days before coming here, hoping to be able to find an answer without bothering anyone here, but things just didn't go as planned...

Create a program where the user can find the highest number and the smallest number from a list of values It needs to operate as follows: Enter a value (number) in the TextBox and click on a button [Add to list]. Once this is done, the program analyzes if the number is the highest entered or the smallest. To view which is the smallest and largest, a second button [highest and lowest] will populate fields (texboxes) with highest and lowest numbers. I've attached an image of what the program should look like.

I keep track of a score system for all users in a sorted list;
dim Scores as new sortedlist(of string, integer)
I can easely increse points for a cirtain person by;
scores("peter").value += 1
Now I need to display a top x list of the users, if users have the same score, it should sort alphabetically on the name. Of course it's also possible that users have the same score.I've already tried to make a new sorted list with as key the score, and added to that score the username. Later when displaying the scores, I've replaced the username with nothing. The only problem in this solution is that the numbers are sorted on asci value which has this order:
0
1
10
2
3
4
Also, if you make a sorted list like this:
dim Scores as new sortedlist(of integer, string)
You can't have two people with the same score... So, there must be something possible with the iComparer to sort on integers right?

I'm not sure where I'm going wrong with this. it's supposed to let the user add scores to the list, then calculate the total, average, and count. However, it doesn't let me add more values to the list. Any help whatsoever would be awesome! Keep in mind, I am new to VB and programming languages, and was just playing around with code hoping for any sort of positive result, and therefore some of the code may not be necessary, or make sense. Here's what I have now:

I am writing a noughts and crosses game and I want to be able to keep score everytime each character wins a game, I have written a sub routine to handle this but it seems to count up in 5's and 10's??I have used a global variable like this Dim i As Integer = 1 then declaired that variable in my sub like this i += 1 (I thaught that this would just add 1 everytime X won a game)then used the variable i to add the score to the label control that keeps the score for the character X.My question is, am I using the correct syntax (+=) for the variable.

I currently have a who wants to be a millionaire game that I have made in visual basic 2010. Each question is in its own form. Form1 opens at the start, and question 1 is opened by a button click on Form1. The user has to click on the picture box at the side to show the text for the question each time. If they answer incorrectly, it displays a message box, opens an input box asking for their name, and goes to the form with the high score list, Form17.
Upon opening Form17, I want the scores to load and be displayed in the list box. The high scores are saved in a text file at C: est.txt . Upon clicking menu or end, the high scores are saved to the text file.

I have been reading extensively about searching generic lists in VB.NET with the usage of delegates.However, I still cannot seem to grasp how to achieve what I want to, which I believe is frustratingly simple! I have a list populated with instances of an object with three parameters (fields/ variables).When I receive a new object to add to the list I want to search the list for the "layer" field.If the field matches then I will replace that row (object) in the list with the new object, if no match is found then I will add it to the list.

My problem is probably something simple..I am trying to load a list of a perticularcustomer.I will have to load the list of all the purchases they have make (amount of tickets purchased (rseat). It runs fine, but when I change the file name from fri to saturday and keep the call name the same it still searches to the name that is in the call name textbox. I dont want it to do that. I want it to say the there are no reservation for that name if I change the file.here is part of my code.
Private Sub btnSearch_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles btnSearch.Click
'resets file reader and put to the top of txtfilename

I want to use a System.Collections.Generic.List<Of T> and store custom objects in the list. I then want to filter the list by my own custom defined criteria and return a System.Collections.Generic.List<Of T> of all the objects in the list matching my search criteria. For searching in Java, you would create an object that implements the comparator interface. The object would then be passed as an argument to the list's sort method. Is there an equivalent VB way to do this BUT when searching for items in the list?I have looked at using delegate functions, but these pass EVERY item of the collection into the function, which is not efficient in any way.

I want a form to search a directory (which i specify in the code) and then list all files with a file exstension that is .amxx .And that's not all, it should list them in a checked listbox.And of course a little + is that it only list the name of the file, not the hole directory + filename. But that feuture i don't really need, just for good looking.I looked into the problem and i tried something with DirectorySearcher but with no success.

It seems simple enough, but apparently I cant figure it out. Theres more to my actual problem, but once I figure out this concept then I can do the rest. I want to search a list for a given string, and if it matches, then print it out. If it doesnt match, then it moves to the next item in the list. If if doesnt find any matches, it says "no matches found".

Okay so i have a very large list of string (500 000 strings) i want to check the number of duplicate strings and maybe even isolate the duplicate strings if i can.
i cant find a fast method to do so :S
i tried using a string array (slower than list) takes ~15mins
i tried using list with the code below takes ~10 mins
that wont cut it :S i need something faster.

In general Combo Box looks for the strings in the list that Start with the text that typed in the textbox portion of combo box.
I want a feature in combo box which do not just look in the starting of the strings, insted they shold search the maching strings within any part of records i.e. If User types 'Ja' in textbox portion, the the list should show following maches with highlighting the mached records
Micle Jackson
Sandeep B Jakhotya
Javid Akhatar
Suresh Jadhav
Jackie Chan like this.
Similar control is already used by Yahoo Web Site for Search Assistance in its Web Search Combo box. Here if we type say 'bush', it will populate following records
george w bush
jenna bush
bush shoe
bush game
hot dog bush
I want the same with Visual Basic for Windows Form Applications.

I have a problem finding strings that do not exist in a column in a database. I am going to use linq but its more the 'way' of doing I am concerned with.
I have strings like;
MEAL
GPST
EXLEG
EXLG ...etc
I need to find records that does not have this list of strings in, so for example DBML BUT sometimes I can have the string MEALDBML, or more concatenated. So this is a known string of MEAL and unknown string of DBML. I would then want to see that record. I do not know the unknown strings up front, so its a case of feeding in the strings I know are ok, and finding one that are outside that list. I was also thinking of regex?

I'm currently working on a project in which at one point, the user may right click a button which brings up a contextMenuStrip. I am already able to find the owner accurately from that strip, and manipulate the button clicked as follows:
Dim myItem As ToolStripMenuItem = CType(sender, ToolStripMenuItem)
Dim cms As ContextMenuStrip = CType(myItem.Owner, ContextMenuStrip)
Dim buttonPressed As DataButton = DirectCast(cms.SourceControl, DataButton)
But now for the tricky part. Within this contextmenuStrip, I have a DropDown menu with multiple items in there. I would assume you would be able to work your way up the ladder doing casts like above in the manner of
ToolStripDrowpDownItem > ToolStripDropDownMenu > ToolStripMenuItem > ContextMenuStrip
Unfortunately, when I try to get the sourcecontrol from this menuStrip, it return Nothing. Any ideas on how I can get the button that was pressed from this toolStripMenuItem? My current code is as follows (in which the sourceControl is Nothing)
Dim myItem As ToolStripDropDownItem = CType(sender, ToolStripDropDownItem)
Dim dropDown As ToolStripDropDownMenu = CType(myItem.Owner, ToolStripDropDownMenu)
Dim menuItem As ToolStripMenuItem = CType(dropDown.OwnerItem, ToolStripMenuItem)
Dim cms As ContextMenuStrip = CType(menuItem.Owner, ContextMenuStrip)
Dim buttonPressed As DataButton = DirectCast(cms.SourceControl, DataButton)
how to go about doing what I did in that first method, but just working my way up from further down the ladder?

I'm having a problem with my Access database.I have to select the highest ActieAantal before the last action ( )because the last action is always the sum (Totaal).this is a part from my table
Persoonid..........ActieAantal..........acties..........Actieid....... ...datum..........aantal..........totaal
.......... 3 ................ 1 ................... aa ................. 99 ........ 31/12/1975
.......... 3 ................ 2 ................... bb 94 ............. 98 ....... 31/12/1975 ........ 94
.......... 3 ................ 3 ................... cc 10 ............... 5 ....... 17/03/1989 ....... 10
.......... 3 ................ 4 ................... dd 20 ............... 2 ....... 25/08/2003 ....... 20
.......... 3 ............. 999 ............. totaal = 124............. 9 . . . . . . . . . . . . . . . . . . . . . . . . . 124
The next person also has some acties with corresponding Actieid and a Total when I use this query I alway get the 999 values
SELECT Register.Persoonid, Max(Register.ActieAantal) AS MaxVanActieAantal
FROM Register
GROUP BY Register.Persoonid
ORDER BY Register.Persoonid, Max(Register.ActieAantal);
but when I try to exclude the 999 value I get nothing
SELECT Register.Persoonid, Max(Register.ActieAantal) AS MaxVanActieAantal
FROM Register
GROUP BY Register.Persoonid
HAVING (((Max(Register.ActieAantal))<>999))
ORDER BY Register.Persoonid, Max(Register.ActieAantal);
find the highest 'ActieAantal' after excluding the 999 values?
