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'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?

item = item.NextItem

I am trying to create the following program Store in a 1d array a set of 5 place names and in a 2d array the distances between the places.

I think the best way forward is pass a parameter to the function findnumber.
Basically I want to store an integer efficiently. At the moment I'm using Button1 Click' Or whatever I need it for Label1.text+0 But to do this I need to add in another Label and set it to visible.

I am creating a dll with all the functions and subroutines that I use all the time and I decided to create a function that I can pass different types of array to so the function obviously (or not) would have an array of type object. Now I no you can pass any type into an object type but when I pass an integer array into an object array I get an error.
value of type '1-dimensional array of integer' cannot be converted to '1-dimensional array of object' because 'integer' is not a reference type.

I am coding a program that will allow the user to input 5 payrolls for Store 1, Store 2, and Store 3. The total of the 5 payrolls are then added together and shown in the respective Store's labels. A total label is also there to add up all the totals into one number. The numbers in the label must be in currency form. My problem is the numbers don't add correctly when I hit calculate. The first two numbers add together, but then after that the number just seems to subtract a random amount.

View 2 RepliesI'm having trouble with this specific code and on arrays in general. This is what I am asked to do: "In this exercise, code an application that displays the number of students earning a specific score. Declare a 20-element, one-dimensional integer array named intScores with the following 20 numbers assigned to the array: (88, 72, 99, 20, 66, 95, 99, 100, 72, 88, 78, 45, 57, 89, 85, 78, 75, 88, 72, and 88). Code the procedure so that the user can enter a score from 0 to 100. Then the procedure should display using a message box the number of students who've earned that score."
First off, I do not know what I'm doing wrong with my array.. it says there's an error in line 31 saying "variable intSubscript hides a variable in an enclosing block" but I don't know what that means. And lastly, once that is sorted out, I don't know how to code a message box to appear saying how many students have received that score.

I am new to vb net so please cut me some slack if this is a stupid question, I have always used vb6 before, but finding that its less and less supported so trying to learn vb.net by myself. Also I am doing this for a hobby not a profession.I am writing an Console application to read a file sequentially 1 byte at a time into a 1 byte buffer. It then copies that byte into a 4 byte lookup buffer, that moves, ie as the file pointer moves forward by one byte the 4 byte lookup buffer copies the last 3 bytes into the first 3 bytes to accept the byte at the file pointer into the 4th byte of the lookup buffer. I am doing 1 byte at a time because the data I am looking for is not at pre-determind offsets and filesizes may not be a multiple of 4.
[Code]...
Help please its driving me mad It appears as if the byte is not being transferred to the lookup buffer so that it would always be 0, either that or I am not converting it to an integer properly
I am reading/writing a fixed length header into a stream and I need to do the following in VB:
1. Convert a 2 byte integer (int16) into a byte array
2. Read 2 bytes of a byte array into an integer variable
I have a very simple question about converting a byte array into 16bit integers. I am connected to a device through a serial port. It sent me six bytes which represent three Int16 integers. For example, the byte array is called newRecievedData(5) and has a length of 6.
The manual that came with the device claims that the int Format is 8 bit MSB|8 bit LSB. Does that mean the following?
newRecievedData(0) contains 8 high bits of the first Int16
newRecievedData(1) contains 8 low bits of the first Int16
newRecievedData(2) contains 8 high bits of the second Int16
[Code]....
but VB.NET Express 2008 gives me the error that Error 1 Value of type '1-dimensional array of Byte' cannot be converted to 'Short'.
