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

How they relate and differ from each? What are the best practices for version control? Is there a primer about publish online? Or a good book?
And is it possible to make ClickOnce and a msi in one solution of VS 2008? If so, is there any conflict or pitfall?
BTW I am using VB if that makes any difference.

Is there any way to make my programs use a lower version of net.framework other than the newest version 4 that comes with VS2010?I use my programs within a closed network and there isn't an easy way for me to install any software since I'm not the administrator.

I'm trying to add functionality to my application that will disable buttons and checkboxes depending on what version the OS is when the app is launched. I made a test app to test this but unfortunately I can not get it to work. Here is my code:
'OS Check
Dim osValue As Object
osValue =
My.Computer.Registry.GetValue("HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindows NTCurrent Version", "CurrentVersion", "5.2")
[Code]...
*Note - 5.2 is Windows 2003, 6.0 is Vista, 5.1 is Windows XP

I have created a license system for my application with MySql about half a year ago. What it would do is take the serial number and send it to my server if the key was correct it would return a 0 if its wrong the return value would be a 1.The problem was that when the serial number was entered correctly my program would create a "fake file" for example vb.dll in the system.And on run time my program would check for that vb.dll if the file exist it would skip my trial program and run the app as a full version. Half year later i think creating a "fake file" and checking for it on start up is extremely wrong and that's not very good security.How can i check the difference between a full version and unregistered version?

I would like my program to overwrite its previous version such that users don't have to uninstall the previous version before installing the new one.
I'm guessing it has something to do with setting Publish Version (Major, Minor, Build, Revision), Assembly Version or File Version.

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?

I want to get the n highest values from an integer array that has n or more elements. This can obviously done by sorting an slicing the array, but I'm wondering if there is a more efficient way to do this, since sorting a whole array would be quite ridiculous when for example only the top 2 elements of an array with length 4200 are asked for.

getting a formula round off to the next highest .25.example:
2.35->2.50
2.26->2.50
2.24->2.25
2.51->2.75
I can't use the Round function because if I have 2.26 then it will round off to 2.25 which is unacceptable.I have been using the Ceiling function but it rounds it off to the nearest highest integer. Which can add an almost extra kg,lb to my formulas.

I got this code to get the highest value from a dataset, but it now doesn't work properly. I think it only gives me the last row but not the highest value.
Dim adMaxRec As New SqlDataAdapter("select serviceid from service", nwindconn) 'where custid = '" & cutidtext & "'
Dim dsMaxRec As New DataSet
adMaxRec.Fill(dsMaxRec)
Dim maximumrecord As String
maximumrecord = dsMaxRec.Tables(0).Compute("Max(serviceid)", "")

Im am currently coding an application for auto updating ccleaner. Everything worked well until I enabled UAC.. I am using this project: [URL] to schedule the updating process, but when uac is enabled I get every time a message if I would let ccleaner installer make changes to my computer. The auto updating process must be done silently without bugging the user with prompts of uac.
When i manually check the "run with highest priviliges" box in task scheduler it does run without a prompt. But I can't seem to do this programmatically. Or I havent found it yet.

If n2 > (n3 And n4 And n5 And n6 And n7 And n8 And n9) Then
TextBox11.Text = n2

The application I'm doing requires me to "enter the size of an array in a TEXTBOX, then click a button, a list of random number would show up, then re-arrange from Lowest to Highest".For ex, i enter "5" in the TextBox, then an array or list of 5 random number will show up vertically on the ListBox. I already got this part done. Now the thing is, I have to make a For...Next statement to rearrange them from Lowest to Highest.

Public Scores(19) As Decimal
Now This Array is populated with decimal values and i just want to get the index values of the highest and lowest scores.i.e. if the [[scores(3) = 90]] and [[scores(7) = 90]] are equal and highest scores, i want 3 and 7 as integers in return..and same for the lowest scores..I retrieved data from a text file and stored it in Classes.. now i want to relate the above Array and these Classes..
Dim Student1 As New Student
There are total 20 of these classes.. Student2.vName, Student3,vName.. etc etc
Student1.vName = SplitterArray(0)
Student1.vID = SplitterArray(1)
Student1.Score1 = SplitterArray(2)
[code]....
For example, After i get the highest score indexes from scores(19) array i would like to get the name of the related person from Student*.vName Class (If i get 3 and 7 index i the related names would be Student4.vName and Student7.vName consequently)?
