Looping Through Structure?
Feb 16, 2010
I have an array structure called Survey and I'm attempting to loop through all the data and get it printed out. I'm trying to follow the example in my text but I must have something different.Here is my basic structure:
Structure Survey
Dim ID_Code As Integer
Dim Members As Integer
[code]....
I'm not understanding how to fix? The objects and properties to the right of "Family Size: " are getting errors saying "Value of type Integer cannot be converted to System.Drawing.Font.
e.Graphics.DrawString("Family Size: " + Home.Members, PrintFont, Brushes.Black, HorizPrintLocation, VertPrintLocation)
VertPrintLocation = VertPrintLocation + LineHeight

I'm new to VB 2008 after having spent a long time with VB6, so I apologize if this is a stupid question. But I'd really like to have this straightened out.
Let's say I have a pretty large structure that has lots of properties.
Code:
Now say that I want an internal database with about 10 instances of this structure total, describing, say, 10 different products that a store sells. When these values are loaded from a database, they remain totally static. (However, they can be different each time a program loads)
Now say that I have a class. Each instance of this class is a type of that BaseProduct structure. Meaning, each instance of the class pertains to one of the 10 types of products that the store sells. However, this class has additional properties that pertain specifically to each instance, which are not static.
Code:
Now, the problem here is... If I have 200 different transactions, each one contains an instance of BaseProduct. BaseProduct is HUGE, and is largely redundant (only 10 types possible), so I think it's a little silly to include a whole copy of it with EVERY transaction. However, the Transaction class really needs information regarding the base product it pertains to. Is there a way to, instead of declaring a New BaseProduct in the Transaction class, to simply make one of the properties of the Transaction class a pointer to a BaseProduct variable?
In VB6, I would accomplish this by making a BaseProduct(10) array, and then giving each Transaction an ID number referring to an entry in that array. But in VB 2008, using class structure, this is impossible. I can't define the BaseProduct(10) array outside of a class in a namespace, and if I define it in the actual application's form, then the class loses modularity since it relies on the application that's using it.

I am trying to communicate with an external device and i am trying to send a byte array to the external device via sockets but i am always getting a response the message size is too small so i am not sure what i have done wrong. Between the data type there should be no alignment present and all numbers are represented in little endian format. The char array is not null terminated as mentioned in the protocol specifications.
I have to send data based on a struct that embeds 2 other struct. So here's my vb.net code for the struct used to convert to byte array and the sending part.
Public Structure MESSAGETYPE_OIP_Login
Dim Header() As COMMANDHEADER
Dim UserName() As PSTRING

I'm experiencing a problem with the following c-structure:
typedef struct tagTEXTUREPROP
{
DWORD dwSize;
[Code].....
The Marshal.SizeOf obviously calculates a size of 76 and it works with the DLL function, but it leaves me with some bad feelings.

I'm having a problem that's driving me crazy; I can't understand how to convert the XML structure into a class structure (that I want to use to hydrate a XML document).
The XML document looks like this:

<?xml version="1.0" encoding="utf-8"?>
<artists xmlns:opensearch="http://a9.com/-/spec/opensearch/1.1/" xmlns="http://www.spotify.com/ns/music/1">

I'm building a slot machine, and I'm having some trouble.re's the
'Pulls down the slot
If e.KeyCode = Keys.Space Then
PictureBox2.Focus()

When I debug and click space down, my picture box of the knob slides on down to 175, pauses, and shoots back up. The problem I'm running into, is that it doesn't do anything if I try to pull the knob down again. It doesn't bug out or anything, but it just doesn't do it again

I'm trying to write a program right now for my computer science class for a program where you insert text into a text box, (the text being a password), and then click a submit button. The goal of the assignment is to have a program that looks at the user given password and see if it matches the const password (or one of the three const passwords in my case). If it doesn't, it is supposed to loop back so you can re-input the password. Also, If you enter the correct password, the loop ends and you are to get a msgbox (or, in my case three different ones), and then the application closes. We are to write the code so that if the password is wrong "x" (insert 3 as the number I have chosen), a MsgBox will pop up with a message saying
something along the lines of "you have gotten the password wrong to many times.", and then the application is supposed to close. I don't think I could rant on much more, I've done a good (or in my eyes terrible) job of summarizing the assignment.
[Code]...
My problem (aside from, I don't know, a problem with my code itself) is that when It reaches the loop, it goes through all the code again, but I'm unable to change the user given password, and so it just pops up the three failed password entry MsgBoxes (the code for which is temporarily removed), then the failed to many times MsgBox, OR one of the successful message boxes. What I'm wondering is if anyone can help me fix my code so that it functions as desired.

I need a loop to run in the background while my app. is running. The loop has to constantly check for the value of a var and return a value based on the values of the var.
Can a Loop be running constantly without slowing the PC down?

I have a listbox with SelectionMode = MultiExtended. I am trying to capture all the selected values to end up with 1 variable that includes all the selections in the listbox.I'm getting error "Public member 'Selected' on type 'String' not found." at the start of my If statement
Code:
For iLoop = 0 To Me.lstVDN.Items.Count - 1
If Me.lstVDN.Items(iLoop).Selected Then
VDN = VDN & Mid(Me.lstVDN.Items(iLoop).Value, 1, 5) & "','"
End If

On a form I have a series of 20 checkboxes (cbS1 through cbS20). With that I have an integer named 'Count'
What I need to do: When the forms loads it will get a value for Count. I need all the checkboxes that are greater than this value to be checked.
So if count = 7 then cbS8 through cbS20 will be checked.
Im not really sure the best way to code this is. I know I can do it with a giant case statement...but there has got to be a better way right?

I have a csv file with data in it in the format...
EVENT|RUNNER|ODDS
1 - 2 - 1
1 - 2 - 3
1 - 2 - 5
[Code].....
So basically the data contains events, runners and odds. I'm looping through and assigning the variables to the relevant object propeties, alls fine.
The problem comes when I'm checking the next runner id (or event id) to see if it's changed so that I know to create a new object. Well in checking that the id has changed I've already moved one record too far so every time I'm changing to a new id I'm losing one record.

This is for .net frameworke 3.5 and visual studio 2008 in VB.Net.Two things we would like to do: 1) loop repeating node blocks 2) loop (through repeating node blocks) within repeating node block loop
First thing:
How do you loop through an xml that has repeating node block (<STRUS name="1000A") and extract the following node? For example you want to extract the IdentificationCode in the node that has <SVALU name="ZRT" and is from pos="9".So, the following example has the IdentificationCodes (TGJ23, PGA12, TPX12)
<?xml version="1.0" encoding="UTF-8"?>
<DocSplitterReport xmlns:xsi="http://www.w3.org/2001/X .......
<STRUS name="ROOT" lineStart="-1" lineEnd="-1">
<STRUS name="TAC" lineStart="1" lineEnd="194">
<SVALUs>

I posted earlier with a question which was answered quickly and allowed me to fire through almost me entire program There is one last tiny thing I'm having real trouble with.I'm allowing users to search through my XML document for records. I can successfully search through the first record but my loop won't allow the search to go through the other 2 records.[code]It isn't the most efficient code to look at I know.As I said I can successfully search the first record but won't allow me to loop into the 2nd or 3rd record available.I don't know if my loop is wrong or if there is some bad placement with the code.

This works like a charm... loading DropDownList2 with all the items from DropDownList1 without looping:
DropDownList2.DataSource = DropDownList1.Items;
DropDownList2.DataBind();
But, the data from the item text of DropDownList1 is copied into both the text and value fields of DropDownList2. Is there anyway to get both the text and the value fields to populate properly?
