Populate An Simple Integer Array With Variable Of The Same Type?
Aug 9, 2012
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?
Public Enum myEnum As Integer first = &H1 second = &H2
[Code].....
Obviously I can code around this issue, but I can see a scenario where that workaround could be easily missed in maintenance programming, and I'm hoping someone can recommend a simple solution that won't break if, for example, the values in the enum have to change at a later date.
I want to use explicit conversion (CType function in VB.NET) to convert the variable d from double type to integer type and store the result as 132.
Imports System.Console Module Module1
Sub Main()
[CODE]...
This is my code. But Visual Basic tells me an error: Error1Type 'i' is not defined.C:\Users\mihaispr\Desktop\Conversie explicita\Conversie explicita\Module1.vb1922Conversie explicita
I have a problem when debugging a code. On top of class I declare an array, and the length of array is an integer variable which is applied value below declaration of array.
E.g. class declaration Dim array1 (2, integer) as string Public Sub integer = 5 End Sub
So basically, array is created with integer being 0 or whatever, because it is declared before integer was assigned a value. But the problem is, I need it to be declared at class variable so I can use array in different subs.
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'.
Module Module1 Sub Main() Dim array() As Integer = {5, 10, 12, 8, 8, 14} ' Pass array as argument.
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) {}
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]......
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 recently downloaded VB 2010 Express so i am quite new to the language, but i have worked with dark basic, which seems to b very similar.Anyway, my problem is that i cannot seem to correctly set out my array of a custom type/class. i am trying to create two arrays, one of available entities and another of selected entities of which the user selects the entities to be dealt with in irrelevant ways. i have creates a button (called test) which adds some entities to the available list and all the entities come back the same value but they shouldnt be as you'll c in the code. i have run the step into command a found that "available.item(#).Name = " will change all of the entity's names.As of current i am working with lists as the array kept asking for a 'new' statement but i couldnt figure out where to put it.[code]
I've tried posting this to a few forums, even microsoft... Hopefully this forum is the place to be.
I'm programming an application in Visual Studio 2010, namely in VB.net. I have been developing an application which uses a derived class inherited from TreeView, with the aim of putting custom objects on the nodes. The method I have been using is to have a variable array against the node (of type object) which contains variables in custom classes to contain each of the variables associated with the node.
The two problems I had to overcome were, how to serialize a TreeView, and how to serialize an array of objects (of variable type). Good thing is I overcame both of these with some work of some other folks (and 3 days of my own work).[code]....
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]
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?
ive got some simple problem i cant understand how to solve.

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'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
this is for a BINGO game final project that I already turned in but this just bugged me that I could not get the sorting figured out. I am trying to get this to sort the random numbers in to columns under the correct letters but I keep getting the error Operator '>=' is not defined for types '1-dimensional array of Integer' and 'Integer' under the line:
But i am now trying to declare time however i keep getting an error because i cannot get the type correct. I tried the following but get the following error: "Conversion from type 'Timespan' to type 'integer' is not valid".
Dim DeliveryTime as DateTime Dim DeliveryTime as Integer
In my database the DeliveryTime type is set to Time(7) so i would assume there should be 'Time' which i could use to declare it, but there isnt. What is the correct type i should be using?
Here is my exact code. There error is Input string was not in correct format:
GraphDate4 = String.Empty DeliveryProducts = "{ name: 'DeliveryProducts', data: [" If DataReader4.HasRows Then
Could anyone assist me in solving my problem ? My code was written in VB (VS 2003.)I got this error: System.InvalidCastException: Cast from type 'DBNull' to type 'Integer' is not valid. in my code.Here is the code line where I am getting the error: LeadCampusID = CInt(.Item("mkCampusID"))I fixed the error by making the changes in the code as :
If Not IsDBNull(.Item("mkCampusID")) Then LeadCampusID = CInt(.Item("mkCampusID")) Else

I'm creating a login system with ASP.NET and VB.NET, and I have the webpage read a MySQL database for a table with the usernames and passwords. In the 1st column is an auto-incrementing id number, 2nd is their username, and 3rd is the password. Here's the code I have for searching through the table (which is a GridView named "logintable"), but I get the error "Conversion from type 'GridViewRow' to type 'Integer' is not valid. It seems like this code should work, so what's wrong? [Code]
I have this application that basically scan in inventory. Is it possible, when a person completes the scan and clicks complete, to bring up a simple html file afterwards showing the data previously inserted? Or even populate a text file?
I am using a code to generate an id for a table.But it is giving 'Conversion from type dbnull to type integer is not valid' exception.Now I know that this is due to the table being an empty set.But it works properly if there is already a row in the table. [code] When I click on 'new' button it generates an id pattern in the textbox 't1'.But it gives that dbnull exception first.I am using mysql as backend and Visual Studio 2008 as frontend.Any ideas?
