Print Structure Array Variable Contents - Error?
Feb 6, 2012
I have a structure named StudentData, it consists of a studentname, an array of testscoresand the student average. There is also an array of structure objects for a total of 6 students. I have the header, column heads, the student names and the averages printing when I click the print page event. I have tried multiple ways of setting this up to get the test scores to print, these are the structure array variables. When I put in the code to process the arrays testscores, I receive a run time error that I don't understand

I have a structure to hold a student name, an array to hold 5 test scores, and an average score. I have created an a array of structures for 6 students. User input is setup through text boxes. I want to calculate the average for each student. I have made a function to do this. What I am having trouble with is how to pass the array of test scores to the function.
Here is what I have so far:
CODE********
Public Const intMAX_STUDENTS As Integer = 6
Public Const intMAX_NUMTESTS As Integer = 5
Public student(intMAX_STUDENTS - 1) As StudentData
[Code].....

This is my structure...
<Serializable()> _
Public Class AcctRecords
Public Amount() As Long
Public DateC() As String
[Code] .....
This is where I try to create a new instance but I get an error that states:
Overload Resolution Failed Because No Accessible "NEW" accepts this number of ArgumentsPrivate Sub FixMasterArraySize(ByVal Cnt As Integer)
ReDim Preserve Acct.Master(Cnt)
For I As Integer = 0 To Acct.Master.Length - 1
Acct.Master(I).AcctType =
New String
Next
End Sub
If Acct.Master(I).AcctType was a Boolean type there would be no error..

I have to create an array of structure type in VB.net. but I am getting error while marshaling this error. I have to pass this array of structure type in to Dll function.
Code:
Structure declaration:
<StructLayout(LayoutKind.Sequential, CharSet:=CharSet.Ansi)> _
Public Structure dx_entry
<MarshalAs(UnmanagedType.ByValTStr, SizeConst:=10)> _
Public dx As String
[Code] .....
I am getting the following error:
An unhandled exception of type 'System.ArgumentException' occurred in Audit_Demo_2307.exe
Additional information: Type dx_entry[] can not be marshaled as an unmanaged structure; no meaningful size or offset can be computed.

Basically on my form I have a listbox containing data. Under the listbox I want to place a button named "btn_PrintData" or something to that effect. The user will click this, the print dialog box would come up and bingo they could print the contents of the listbox.

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 am trying to create a code where I placed sets of numbers in an array.I'll use a masktextbox to have the user enter the numbers to match what's in the array. If the user enters the number, ex: social, and the data is correct (matches the numbers in the array), something happens if the number entered in the masktextbox does not match any of the number sets in an array then another thing happens.The masktextbox so far only validates format and gets number only, however, I want the number entered to match whats in the array.

I am trying to figure out how to print specific members of a structure when I only have to pass the structure itself i.e.
Dim Point1 as PointF = New PointF(15,30)
Debug.Print(Point1) ' This will output "{X = 15, Y = 30}" by default
I am trying to figure out how I can do the same with my own strucutres, for example:
Dim Point2 as PointF2D = New PointF2D(15,30)
Debug.Print(Point2) ' This will output "ClassName.PointF2D.Point2"
How can I get my structures, when passed to a print statement, to print specific members of that structure by default? P.S. Please give another way other than overloading the .ToString function.

I have a listbox control (in a WinForms application) that lists a bunch of statistics about records selected from a database.
Is there an easy way using VB .NET to take the contents of this listbox and send it all to the printer, or at least have one of those standard windows print dialogs come up, prompting the user for which printer to send the listbox contents to? Doesn't have to be fancy or anything.
