Referring Between Classes?

Feb 21, 2010

I am trying to do is get interoperability between my "mainwindow" and a class. As far as I know the way to do this is to create an instance of the class (in "mainwindow") for example and then use that instance to call the functions etc... This works. However I want to allow the class to call functions in the "mainwindow" The moment I declare the instance on the class as well it goes into an endless loop.

Close Form By Referring To Name?

Feb 24, 2009

I�m using a loop to open up a number of forms in my app. The forms are named after dates from a db. They are "created" at runtime so to speak.

Everytime a form is opened, the name adds to a dropdown list in an mdi parent form. The first item in that dropdown is a "close all". I want that item to do just that - close all the forms corresponding to the names in the dropdown list. I�m thinking of looping with an integer, starting on 1 (since the "close all" is 0).

So I need something like:

forms(mdiparent.toolstripmenu.dropdownitems(i).close

Referring To A 2nd Imported Project, Within The Same Solution?

Jan 23, 2011

I Imported 2 programs that I made into one solution. I made a "BIG" main menu (new windows form), put two buttons. I code one button to open up the first project (that works fine). I code the other button to open the project I imported, however it says that the name is not declared. Am I doing something wrong?

here is my code for the "BIG" main menu:

[Code]...

now only the "Original name of first project" appears to be not declared, if I delete "Original name of first project", then "the project I imported"is not declared and so forth. Note: These are not the exact names I called my forms. I'm just trying to explain it clearer.

Referring To A Class In The Solution Explorer?

Jul 20, 2009

I have added some classes to my project and now i want to define a variable as one of the classes, for example the class is called xml and i want to create a variable called XMLfile and have it as the class XML.

Can this be done? Or can variables only be declared as types (like Integer, string, etc)?If you're not living on the edge, you're taking up too much room

Referring To A Previously Existing DataSet?

Jul 21, 2011

I'm working on a very basic VB.net frontend for an Access database and have stumbled upon a problem.

Dim ds As DataSet
MaxRows = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows.Count
i = 0
Private Sub Navigate()
txtCourseReference.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(1)
txtCourseName.Text = ds.Tables("Course_assignmentsDataSet.tblCourse").Rows(i).Item(2)
End Sub

I get the error that Object Reference is not set to an instance of an Object. I think this is because I haven't defined the DataSet as "Course_assignmentsDataSet"- the one I want to use- but I'm not sure how to do this.

Program Function - Says, "The Type For Variable [variable] Will Not Be Inferred Because It Is Bound To A Field

May 18, 2012

Public Class Form1
Dim x, c, number(0 To 19) As Integer
Dim s As Integer

[CODE]...

The variables in the brackets [example] do not actually have brackets in them in the original code. These are where the issues are. For both variables, it says, "The type for variable [variable] will not be inferred because it is bound to a field in an enclosing scope. Either change the name of [variable], or use the fully qualified name (for example, 'Me.[variable]' or 'MyBase.[variable]')." Now, I'm not entirely sure if this is a stupid question or not, as I'm used to VB '98 because that's what we use in my programming class at High School. let me know why this won't work.

-Note: The intention of this program is to continually loop the generation of numbers for this list until I tell it to stop. Button1 ends the program, Button2 generates the list one time only, Button3 is supposed to loop the generation of the list, and Button4 is supposed to end the loop, but not the program.

VS 2010 Compiler Creates New Variable Automatically When Use If Statement Without Strictly Declared Variable?

Jan 10, 2011

Say that i have the following code that parse about 20k records from the DB.

Code #1

vb.net While reader.Read()
list.Add(If(Integer.TryParse(reader(0).ToString, 0), Integer.Parse(reader(0).ToString), 0))
End While

And then another code which does the very same thing but it seems to be a little cleaner.

Code #2

vb.net While reader.Read()
Dim storeowner As Integer = 0
Integer.TryParse(reader(0).ToString, storeowner)
list.Add(storeowner)
End While

This is what i am confused about; does the compiler creates a new variable automatically when i use the if statement without strictly declared variable? What approach is better in sense of performance?

Variable Naming Conventions To Illustrate Variable Type And Where Variables Are Declared

Aug 24, 2009

I am looking for a good resource on variable naming conventions to illustrate variable type and where variables are declared. So I will have public variables, Private variables, private or local variables. I also may want to declare variables with the same name in different class code (i.e. in the code behind different forms). I am assuming good coding would dicatate a prefix for declaration location.

Object Variable Or With Block Variable Not Set - From Property Get With Bindingsource.current?

May 31, 2012

Now I have the need to get a current value from a bindingsource in a property of a user control.In a previous thread I had tracked down the "Object variable or With block variable not set" to the return in the Get block of a property. At the time I was only using the Set so I just commented out the offending code until I needed it.

[Code]...

The error does not occur during a system compile, only upon saving the container object of the user control. As I said the Set works correctly, only the Get causes the error.I would like to know what I am missing/misunderstanding and am open to other suggestions of handling retrieving the current value of a bindingsource in a user control.
