how can I set the size of my integer array if it is determined at compile time?
Class Modlue
Private thisNumber() as integer
Private Sub Button1_Clicked(byval sender as object, byval e as EventArgs) Handles Button1.Click[code]......
In the below code I am getting the following error on line If (Not hash.Add(Numbers(Num))) Then Value of Type 'Integer' cannot be converted to 'System.Array'.

I have used the following code to read a memory address from a pointer and offset previously however, Now I've come to use it again and can't figure out how I got it working last time, I'm receiving the error "value of type '1-dimensional array of Byte' cannot be converted to integer" highlighting the BytesAtAddress variable in the ReadProcessMemory calls.
Public Shared Function ReadPointerFromMemory(ByVal BaseAddress As Integer, ByVal PointerOffset As Integer, ByVal BytesToRead As Integer, ByVal pHandle As IntPtr) As Integer
Dim BytesAtAddress As Byte() = New Byte(BytesToRead - 1) {}

I know vb.net does not include pointers like C language. but I am trying do populate an simple integer array with variable of the same type for example :
dim variable1 as integer = -1
dim variable2 as integer = -1
dim intArray() as integer = {variable1,variable2}
[code]....
it is a very simplyfied verson of what I want to do.I want to change the value of ma variables with my array referencing them with an index as if my variables were pointers of integer in c++ for example so that normally after the example, both variable should hold the number 3 instead of the number -1?
At the top of the code that follows is the method in c# into which I'm attempting to pass an integer value. Is there anyway I can change the assignment statement to the byte() PDUToSend to take care of the error I currently receive; Value of type 'Integer' cannot be converted to '1-dimensional array of Byte'.

I don't know what to do....

Whats wrong?
I found out that you cannot set the array size for a structure when you are making it, i.e
[Code]...
I have to fix this by making a variable with type made by Structure bullet and then redimming it, i.e
[Code]...
This means for every variable with the bullet type i create i have to redim. Is there a way i can set the size of .mesh with .capacity for every single variable created with the bullet type automatically?
1] Is there a way to declare an array of mixed type [e.g.] column 1 as string, columns 2 through 5 as integer.
2] Is �Dim myArray( ,5 ) as type� a valid statement and if so will it result in a 5 column array of unspecified length?
Is the integer data type is structure? And if yes what is the original code of it?

i have a productid that i get as a result of sql query. The data type of productid in database is int

It's good to be back in this forum again hoping someone could help me solve my problem again xD My goal is to import .txt to db.
This is my code
[code]...
Some of the records are inserted but when the code read the part where there is an empty/null value in the column where they are assigned as "decimal" the error message "Error converting data type nvarchar to numeric." pops out.
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 a newbie in VB and I got a piece of code which can display the current running program. I need to use that in VB2005 and I got the below error message. Can anyone help how to fix it?[code]
View 18 RepliesI'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

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)

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?

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?

Whats the font size real meaning? since when i use Arial font size 10 in the report its gonna take different space than the textbox im using (Both using exactly same font type/size/unit) its kinda if i set 10 milimiters to the font size why would the i and M for example have so diferent size.
i wish it was like in the Notepad where all the letters take the same space. what i need its to give a certain texbox(in the report) with auto grow to have always the same lines of height but its not posible to calculate it from vb b4 being inputed to the report.
In order to re-sort the data received in USB easier, I send the data array received in USB (declared as Byte) to a temporary array (declared as SByte) to re-sort. I declared the temporary array as SByte just for easy sorting. After I compiled, an error message came up "make sure not divided by zero". I tried to use convert.SByte but still didn't help. Is it not allowed to send data to an array with different data type declaration?
