Properties - Call Setter From Within Getter?
Jul 29, 2011I have a class like this:
Public Class MyClass
Private _intList As New List(Of Integer)
Private _avg As Decimal
[code]....
The Getter is calculating average and calls Setter to save the value. For some reason I cannot understand, the average is always 0. For example:
Dim c As New Class2()
c.Add(1)
c.Add(2)
c.Add(3)
Console.WriteLine(c.Avg.ToString()) ' This will print 0

View 6 RepliesDatabase - Running SQL Query From Module With A Function Call From The Form?
Jan 28, 2010I have a form set up where I want to run the function PopulateGrid on it's Form_Load event. I have initialized the DB connection as follows:
Private Sub Main_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
LoadConfigFile()
cn = New OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0; Data Source=" & config("DatabasePath") & ";")
cn.Open()

Now, I want to run the PopulateGrid function directly after I connect to the database as shown above. I'm confused as to how I'd use a database query in a module when the database is initialized in my main form. Would simple setting the variable cn to public work?

How To Read/write Properties To Xml File For Later Retrieval
Aug 31, 2009First off I am fairly new to VB .net however I have had some success in my project so far. I am creating a simple envelope accounting program for personal use. So far I have some basic forms created and have my class defined and a few methods for calculating my balances as well as changing the property data I want to work with. I now want to take this property data and save it to an xml file that I can easily retrieve the data into another form and save for later.
Here is a screen shot of the form used to gather the property data for my class
Here's the class code:
Public Class EnvelopeSystem
#Region "Identification"
Private eUsername As String = ""
Public Property Username() As String
[CODE]...
I am looking for advice on how to get this to xml the most efficient way possible. Also if there are any blatant errors or easier ways to code what I already have I am still very new at this and would be glad to see easier more efficient ways of coding.

Read-only Properties With No Parameters Overload Eachother?
May 13, 2011I've noticed that a class can "overload" a read-only property of its parent class, even though this isn't allowed within a class. I don't understand why this is allowed or what (if anything) it accomplishes.
[Code]...
The signature of mySubClass.SomeProp is identical to myClass.Prop—how can the former overload the latter?
In practice this seems to function just like Shadows, is that true?
VS 2010 Program Crashes As Published Executable, Not As Program Running In Studio Or Express?
Jun 6, 2012I wrote this VB program to be able to throw a device we developed into programming mode where we use an ATMEL Flip installer to upload new firmware. I can program one device after another running the application off of Visual Studio Express 2010 or Visual Studio 2010, but when I go to publish this file and run it on another machine, it becomes unstable and crashes after each upload. On those same computers if I run the raw unpackaged program under Visual Studio Express, the system does not crash, and I can program devices repeatedly.
View 5 RepliesRead A String And Call The Method Of The Same Name?
Nov 2, 2009Is it possible to read a string and call the method of the same name?For example: I have many buttons and if the user presses the button named A1, I want the Sub AI() to be called. I don't want to do an explicit If-Then for each button. Rather a common ONCLICK method that is called by all buttons and another method (the same name as the name of the button) is called.
Example:
Sub Click(byVal buttonName as string)
call ButtonName ' <<<< Error. ButtonName is string and not a Method.

View 1 RepliesRead A Games Log File As It Is Running?
Sep 9, 2011I'm trying to read a log file for a game so I can extract certant info from it and track my stats as the game is running, but I keep getting access denied error for the log file. I would also like to have the log read only after it has been changed but the event handler never fires. I'm assuming it has to do with the access error. Can someone give me an example of how to watch a text file that's in use by another program and read it after it changes. The code I have works if I open the file in notpad, change it then save it but not when the game is running. I did it once before for the same game but lost my code and there are other programs that parse the log file so I know it can be done.

Call Function - Invalid Attempt To Read When No Data Present
Mar 25, 2009When I run my application the following code prompts an error. Ideally, I want to populate the TxtOracleNo with a value read from another table on my form based on certain conditions i.e., prac_no, prac_eid and pay_method is the same in both tables then populate the Oracle No on TxtOracleNo text box.
The error given is
"Invalid attempt to read when no data is present"
The function is shown below
Private Sub Oracleview()
'Open the database.
'Delete any existing record
Dim cmd As New SqlCommand
Dim conn As SqlConnection = GetDbConnection()
[Code] .....
I checked that data in the database and it is available in both tables. Probably, the problem is where I call the function. Presently, I call it on loadform.
