Object Creating Code & Passing Values To SR?
Mar 29, 2011
This code works, as is, on my system. Problem lines are commented out. The last three commented lines are the problem.It creates the objects alright but a line that should send a message into the list box doesn't work. I am almost sure that the problem is in passing information into the sub routine. Forgive my use of ALL CAPS as it helps to see my comments on comments. A few comments in passing information to SRs would be helpful.
Also, how it is that I can comment out the .Name option and it still works?(I hope that this shows up properly. If it ends up as a big useless paragraph, I will repost it after learning how to do it properly.
Here is my
Public Class Form1
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
' -------------------------Create ann exit Button -----------------------------------------------------
Dim btn As New Button

I'm trying to setup a WCF web service to be consumed by JavaScript using JSON and jQuery.I've noticed that you can send JSON without a DataContract if the service method parameters match the naming structure of the JSON object:
<ServiceContract(Namespace:="http://foo.com/bar")>
<AspNetCompatibilityRequirements(RequirementsMode:=AspNetCompatibilityRequirementsMode.Allowed)>

I am making use of a 3rd party dll and am encountering some strange behavior in VB, which doesn't occur in C# Perhaps someone can explain what is going on. Anyhow, I am making use of a method in this 3rd party library which accepts an array parameter ByRef. The end result is the variable should remain null after the method call, but it is returning initialized for some reason.

I'm having this problem with my code and cannot seem to get past it although it was working fine before. The error is "An error occurred creating the form. See Exception.InnerException for details. The error is: Object reference not set to an instance of an object." The code is:
CODE:
I am trying to get information to be pulled out of a database and show in text boxes on another form (frmviewsdets). The error occurs when it gets to the line frmviewsdets.txtsnumber.Text = rdr("StudentNumber") and even when a breakpoint is applied there it just moves on to the next and so on.
I have tried to show frmviewsdets before I pull the data out of the database beut I get the same message.

I think I'm getting hung up on syntax here. I've got 2 forms and am trying to pass a textbox value from the 1st form to the 2nd. The textbox value is an unique ID #, so it's an integer value in the database. The ID displays in the textbox just fine on the 1st form. When I try to access the value of this ID textbox in code in the 2nd form, I see that the value is empty, or equal to "". But I see a valid ID # on the 1st form. Here's the code that shows me that the textbox equals "".

I'm pulling up a a webpage in a control and the page is full of Java functions. I'm able to use execute a function using invokescript. That works out really well. But here's the thing. There's a function that takes the value of a rendered textbox and uses that data to perform the function.The textbox is usually hidden until another function activates it to enter data.What I want to do is to bypass having the textbox come up and execute the function with predefined data. Basically the function refers to the data it gets as txtWrapupComment.value whereas txtWrapupComment is the textbox it's getting its data from.
So, the bottom line, is there a way I can declare txtWrapupComment.value and pass it before I execute the funtion?

I am having some trouble creating an object array of different object types. Here is what I have so far:
Public Sub New()
Dim b1 As New Book("Book Title 1", "Gold Book Publisher", 1.0, "Bob Jones", "192DJDJD212", "01/02/10")
Dim b2 As New Book("Book Title 2", "Gold Book Publisher", 1.0, "Bob Jones", "192DJDJD212", "01/02/10")
Dim b3 As New Book("Book Title 3", "Gold Book Publisher", 1.0, "Bob Jones", "192DJDJD212", "01/02/10")
[code]....
If I define the array As Book (Public publicationArray(6) As Book) or Magazine (Public publicationArray(6) As Magazine) I am able to access the properties of that class but not both. I think I need to define a type for each array instance but not sure how to do this.

I occasionally find myself passing this or Me to a child object. Such as this condensed real-world example...
Public Class Entity
Private mValidator as New EntityValidator()
Readonly Property IsValid()[code]....
I'm concerned about .Validate(Me).I get no warnings or Code Analysis violations, but it just feels wrong. I get nervous about infinite recursion and garbage collection.

I am creating a procedure and would like to know if I can pass the name of a property. I.e ComboBox1 so I can change the properties of that object. What I have done is create a procedure to populate a Combobox from my MySQL database. What I want to do now is populate the relevant Comboboxes without having to create a new procedure specifically for each combobox. I can create a procedure for each Combobox but the whole reason for procedures and functions are to minimize repetitive code and to make code easier to manage.
At the moment my procedure is ProcedureName(ComboBox1, "DatabaseName", "DatabaseField").
What I want to be able to do is do
ProcedureName(ComboBox1, "DatabaseName", "DatabaseField1").
ProcedureName(ComboBox2, "DatabaseName", "DatabaseField2").
ProcedureName(ComboBox3, "DatabaseName", "DatabaseField3").

My problem is that I have two forms, Form1 and Form2 ...on Form1 there is a TextBox called txtTotal (this contains the calculation of Ticket Prices, thus it's a numeric value) and on Form2 there is a TextBox called txtTotal2. All I want to do is get the same number that appears in txtTotal on Form1 to appear in txtTotal2 on Form2 .However whenever I try some of the help tips online such as using a declaring txtTotal as global or friend it dosn't work, and any other code iv tried attempts pass the textbox value as String which brings an error.

Can anyone give me the best method of passing back a value from a Thread?I have some procedures that I have set up as threads that I'm starting at the same time.My main function then waits until the threads are done and I'm needing to get back some values that the threads have created.Is there a better way to get these values back rather than just having them set a global variable with the returned value? Also, what is the proper way to wait for a thread to to be completed?I've just got a loop waiting for the Thread. Thread State property to not be in the Running state.So if there is a more proper way to wait for the thread to end I would be interested in knowing it.

Im having a hard time trying to pass the values from a list inside of a class. Im trying to display multiple lines of values from a list inside of a class. My "client" class stores multiple lines of values into a list(of class transaction), with the number value(num) counting each transaction that it adds to the list.
Code:
Public Class Client
Private m_tranlist As New List(Of transaction)[code]....
im trying to display each line that is stored in the list in a label, and im having major trouble. I know all of the results are added into the lists, but how do i call the list in my main form in order to display each line of all of the values? Would I have to look up an index or something?

This may not be the place to ask this, if not, you can move this post to the SQL forum but I have an application that I'm building which pulls dates from a database. The start value is stored as payPeriodStart date and I add 7 days to get the end date. What I need to know is, is it possible to store those values and pass them to a Stored Procedure? Currently my stored procedures have "static" dates in them ie:
where dateadd (n, Timestamp, '12/31/1899') - ([LoggedIn]/1000)/60/1440+1 Between '10/3/2010' and '10/10/2010'
and I'd like those values to be
Between payPeriodStartDate and payPeriodEndDate.
