String With Multiple Integer Values To Integer?
Apr 5, 2009
I'm trying to set an Integer value from my.settings.The values comes frpm a listbox, and then inserted to settings (set to specialized.StringCollection)The problem is when i'm trying to get the values and apply them to my function.Error code: Conversion from string "65 & 71" to type 'Integer' is not valid.To me it looks right, but maybe i'm missing something.
Code: Dim test2 As Integer Dim test As System.Windows.Forms.Keysm trigglist As New StringBuilderor Each item As String In

I have a LINQ2Entity problem, I want to get the value, string, from a database, so I select FProducts.Serial_number, and to end the query, I do .ToDictionary. The problem is, it tells me that it doesn't have sufficient parameters, to convert ToDictionary. So I need something like select FProducts.Serial_number, Nothing). ToDictionary. Also FProducts.Serial_number, 0).ToDictionary doesn't work.
Sub GetStatistics(ByVal ProductNumbers As List(Of String), ByRef Passed As Integer, ByRef FailedProducts As List(Of String))
Passed = 0
FailedProducts = Nothing

ive got some simple problem i cant understand how to solve.
str(1) is an array and integer(or double, tried both)
a(1) is an array and integer (or double, tried both)
a(1) = a(1) + 1
Label1.Text = str(1) + a
the big part is where i get: operator '+' is not defined for types 'integer' and '1-dimensional array of integer'.why do i get that message and what does it mean? how do i make the code do what i want?

I faced an error when upgrading VB6 code to VB.NET. The error occurs at AddressOf WindowProc
AddressOf expression cannot be converted to 'Integer' because 'Integer' is not a delegate type
My declaration for SetWindowLong is:
Declare Function SetWindowLong Lib "user32" Alias "SetWindowLongA"(
ByVal hWnd As Integer,
ByVal nIndex As Integer,[code]....
What is the reason for the error I get?

I'm trying to create a linked list of an array of integers. Why is the following implicit conversion required?
When I run the code that contains that conversion, I get the following error.
As a real-time data acquisition user control data (a packet of an array of bytes) arrives every second, is converted into an integer array and inserted into a linked list.
The most recently arrived data is painted as coordinates on a grid at the right of a PictureBox using Graphics.DrawLine (pen,X1,Y1,X2,Y2).
The oldest data (arriving 120 seconds ago) will be drawn at the leftmost portion of the Picturebox.
Why a linked list rather than a list? To display 120 views of time sequence data, the draw routine the most recently inserted node to a node that points to Nothing. How do I limit the length of the linked list to 120 nodes and always ensure that the last node points to Nothing?
Do While Not item Is Nothing
item = item.NextItem
Loop

I'm trying to convert a VB6 project to .NET, but I get problems with some callback functions, and the following message comes up: "AddressOf' expression cannot be converted to 'integer' because integer is not a delegate type" I've seen several solutions to similar problems like this, but I am not able to understand this issue with delegates.
After the conversion, the code look like this:
Declare Function vsmsgwSetDataPackageCB Lib "vsmsgwW.dll" (ByVal PACKAGE As Integer, ByRef arg As Integer) As Integer
Dim arginitP As Integer
[Code]...
Which gives the error: Method 'Public Function PackageCB(HisNodeID As Integer, ByRef data() As Byte, ByVal length As Integer, ByRef arg As Integer) As Integer' does not have the same signature as delegate 'Delegate Function DelegatePackageCallback(hwnd As Integer, lparam As Integer) As Integer

I am new to EF Linq and I have been struggling with this query for a few days. From reading this forum, I have managed to get this far:
Dim noPic = (From f In myEntities.FriendLists
Where (f.UserID = Profile.ID)
Select f.FriendID).Except(From g In myEntities.GuestLists
Where g.EventID = _id
Select g.FriendID)
[Code]...
I am trying to get everybody from the FriendList who is not already on the GuestList to display in a Repeater control. After reading the forum I was able to append .First() to noPic at the myNoPic declaration and finally get a result but that only gave me the first element. Does anybody have any advice on how to accomplish this?

This is giving me a headache. I have this link query here that grabs an ID
Dim mclassID = From x In db.SchoolClasses Where x.VisitDateID = _visitdateID Select x.ClassID And then later on I have this linq query
ViewData("Staff") = From t In db.Staffs Where t.ClassID = mclassID Select t
I've tried quite a few things but to no avail. I've attempted casting, converting, Is operand, etc.

I'm just writing a bit of code to compare an id of integer with an id of integer? for example:
Dim id As Integer = 1
Dim nullId As Integer? = Nothing
Dim areEqual As Boolean
areEqual = nullId = id
When I try to compile the code I get a compiler error: Option Strict On disallows implicit conversions from 'Boolean?' to 'Boolean'. Whilst it's very simple for me to work around this, I was hoping that someone might be able to explain what's going in the compiler to give this warning.

I'm working on a simple BlackJack (player vs dealer) system, that I plan on making gradually more advanced. However, while everything works brilliant, I'm yet to find a logical solution to declaring an Ace as both 1 and 11.So my question is, how do I pull this off. Below is the "New Game" logic (code) so it should give you an idea of what I'm working with (note how player scores are added together, I'm sure it's easy enough to understand...).I'd like lblPlayersum to still be a usable integer, though I'll rework everything if noone has a logical solution.Just quickly note that the "Cards" array is purely used to coordinate images."CardsVal" coordinates that values within the deck. Arrays 48, 49, 50 and 51 are the aces. (Currently defaulted to 11).[code]

My problem is that I have two forms, Form1 and Form2 ...on Form1 there is a TextBox called txtTotal (this contains the calculation of Ticket Prices, thus it's a numeric value) and on Form2 there is a TextBox called txtTotal2. All I want to do is get the same number that appears in txtTotal on Form1 to appear in txtTotal2 on Form2 .However whenever I try some of the help tips online such as using a declaring txtTotal as global or friend it dosn't work, and any other code iv tried attempts pass the textbox value as String which brings an error.

I am trying to reset all integer values to "0" with a reset button.I try not to use hardcoding by simply set them one by one. So my idea was checking all the variable's type and set them all to "0".
I tried to use this methode, from someone in this forum (sorry, I forgot the name but this is very helpful...) For Each ctrl As Control In Me.GroupBox4.Controls 'Check and see if this control is a TextBox
If Object.ReferenceEquals(ctrl.GetType(), GetType(Label)) Then 'Check and make sure this s the "TextBoxToExclude"
'CType(ctrl, CheckBox).Checked = False
CType(ctrl, Label).BackColor = InactiveColor
End If
Next
But when I tried to find the code, I couldn't get it.So, if anyone knows how to do this,

I am working with a future value application and I am trying to display the calculated future values in a listbox. For instance, I input the monthly investment, the yearly interest rate and the number of years into textboxes and I want the application to list out the future value for each year until the number of years in which I entered is reached. I cannot figure out how to get the code to display the value after each year. I am trying to use the "mod" operator to display the value each time the 12th month comes around.[code]...

i am having trouble displaying the values i get from an IList(Of T) and displaying that in a listbox found on another form. I have used a for loop to get the values from the IList, then i can display that in a msgbox. for eg:
Dim j As Integer
Dim path As String = ""
For j = 0 To best_tour.Count - 1
[code]....
best_tour is ot type IList() path keeps the name found in the list everything works fine inside the loop..but it does not populate the lst_output listbox.I have tried using files, but in vain. It just get the values from the list but does not display that on the listbox.If that can help, then listbox is found in a panel on the form2, but taking it out of the panel does not affect anything.

Why is it that in parts of the .Net architecture that ARGB colours are expected be as type Integer when ARGB is outside the range of Integer? (ARGB requires 32 bits of precission, but Int has 31 bits of precission).Now of course I could just do a conversion, but what freaking conversion to use??? (I'm not affluent with all the VB global methods and the sort)
I've tried things like:
Code:
Dim value As Integer = &H80000014
Dim uvalue As UInteger = CType(value, value)
''overflow others include Convert.ToUInt32 -> value was either to large or to small and a few others all offering up nonsense about overflows, when all I freakin' want is a colour that Microsoft's own engineers have done stupid things like expect Integer values in places where UInteger should be, or vice versa. How about some consistency...
Code:
Dim value As UInteger = &H80000014 ''<- not represntable as a Uinteger???
Dim uvalue As UInteger = 2147483668 ''<- same value in decimal, same exact value! and it works this says it's not representable as a UInteger?

List1 {1,2,3,5}

I want to have new List3 {4,6,7} which is composed of elements of List2 that are not in List1. I know I can write a nice For Each loop for this but I want it done in LINQ I've been looking for such methods at Enumerable Methods, but I can't find it.
