VS 2008 - Using PrintToFile Method From PrintForm Class?
Dec 16, 2009
I'm trying to use PrintToFile from the Power Packs PrintForm Class and I have a question. I'm able to save the form to a file, but now how to print it later if needed. MSDN says that it's saved as an Encapsulated PostScript file. Adobe Illustrator claims it will open EPS file, but it won't open this one. How I can print this file in vb.net? If you've never used this before, here is my sample code to save the form to file in case someone wants to test it out.
If SaveFileDialog1.ShowDialog = Windows.Forms.DialogResult.OK Then
Me.PrintForm1.PrintFileName = SaveFileDialog1.FileName & ".eps"Me.PrintForm1.PrintAction = Printing.PrintAction.PrintToFile
Me.PrintForm1.Print(Me,PowerPacks.Printing.PrintForm.PrintOption.Scrollable)
End If

Consider a MyForm class that contains a shadowed implementation of Show(). It also contains a CreateForm() method, which accepts an instance of the form and calls the shadowed sub:

I'm working on a base class right now, here's a basic rundown of it:[code]The problem is, in the Public Class bar example, some classes may implement MyInterface, and others don't. What I'd like to be able to do is have the sub New() in the structure in the base class "Foo" be able to tell if the class calling it (either the Base class, or the child class) implements MyInterface or not.

I am looking for a way to pass a class method into a new thread. On my form I have a few object that contain methods.
For example obj1.doWork.
Now I want to do
Example
Dim t as new Thread
t = new Thread(AddressOf obj1.doWork)
t.start()
However I get an error on this saying:
Error1Overload resolution failed because no accessible 'New' is most specific for these arguments:
'Public Sub New(start As System.Threading.ParameterizedThreadStart)': Not most specific.
'Public Sub New(start As System.Threading.ThreadStart)': Not most specific.

I am printing my form by using the printdocument of VS and the printform found in powerpacks. I never got the preview to work so when ever I want to print I send my information on a new form (form1) which I have altered ( colour borders ) so it is printable. To print form1 I have added a toolstrip with a print button so when the user sees all is ok on the form1 he clicks on it which hides the toolstrip and prints form1. All this sequence works fine. The problem I have been getting lately is that I can print on the first try but when I call another form to print the toolstrip ( with the print button ) is always hidden. I have to exit the application and re enter to get it to show up. Any solution to this or even how to print in a better way. (have the preview to work for example ). I have tried to use printdialog to print but I have never been able to send the document to print.

I've been creating short test apps repeatedly to try to understand some of the concepts in VB.NET.For the most part it has been illuminating.I read Bucky's .NET knowlegebase tutorial on passing objects as parameters to newly created forms. He shows how to create a new class that inherits from the base form class and define a New() method with parameters Extending the concept I thought about doing the same thing with a form that was created at design-time (In this case Form2).

Base class has one field to hold numeric balance value. With 2 methods that accept arguments for adding and subtracting the new input calculating new balance. Sub class has four fields dates, transaction, memo and amount.I have a deposit form, and withdraw form. Each time one transaction is entered it creates an object with sub class fields, then adds to the account collection. My problem is not understanding how to call the deposit/withdraw method and pass the current transaction amount back to the base class to alculate the new balance. Does anyone have any links to information/tutorials on how to perform something like this? As you can see with my code I have tried various different approaches without any success.

Supose a base class
Public Class airplane
Private var_num_seats As Integer
Private var_num_engines As Integer
[code]....
Obviously, I don't wish that the class Glider has the method "start_engines" neither the property "num_engines". Otherwise, other child classes may have. How can I supress these property and method in child class, not just ignoring (if I can)?

I'm writing a set of unit tests for a large, complex class called ImageEditor from a piece of legacy code, where image processing and GUI functionality isn't strictly divided. One of the methods in the class, BaseImageChanged, seems to be concerned entirely with how images get displayed and should be disabled in my unit tests to avoid unnecessary complexity. The test project is in C#, and the original code is in VB; my idea was to create a Decorator for the class in C# and then hide the method behind an empty one that does nothing. However, when I try running the unit test, the VB code keeps referencing the old BaseImageChanged method as though the replacement didn't exist. Here's what I'm doing:

I know this is possible, and it is probably something simple that I am missing... I have a fairly complex class to handle deserialization of an XML file. I wish to place a [class].loadfile method within the class. It looks something like this: Serialization decoration left out for simplicity...
[Code]...
The Deserialization is working just fine (that's my own code), but assigning the object value to Me is not correct. What I want is for an instantiation of this class to have a LoadFile method (similar to the XML class LoadFile method) - but I cannot figure out how to set the value of the class from within the class.

Suppose that I want to implement another method for a class namely hasFiles for System.IO.Directory , How can I do that?
for example if I add <Extension()> _ tag before each function or Sub I can add a new function or method for each Control.

I want to invoke a method on a class that i have a reference to. The method that I want to call has a custom attributes. Currently I can find this attributes and call the property of my class Attribute.
is there a way to invoke that method ?

REF: http:[url].....The above reference is where I got the code below.This code adds buttons to Form1. When a button is clicked a messagebox appears stating what button was clicked. I want to have the ClickHandler fill a RichTextBox on Form1 (I added a RTB to Form1). My problem is I can't do a Dim xForm As New Form1 to fill the RTB from the ButtonArray Class. I can place my file's text in a MessageBox so I know the code I added is correct. I also tried placing a Property method on Form1 and using a Accessor to fill the RTB, however it also requires Dim xForm As New Form1. How can I get my data from files to the RichTextBox on Form1 from the ClickHandler in the ButtonArray Class? See ButtonArray Class Below.

essentially I need to create a class that houses the methods and then call the methods in the form but I can't seem to find out what the right code is to call it. I think there may be an issue with the conversion from a double to a string.
This is what I have for the Class
Public Class Aircraft
Dim Names() As String = {"A-747", "A-737", "C-150", "D-240"}
Dim TakeOffVelocity() As Double = {250, 264, 270, 240}
Dim Acceleration() As Double = {33.5, 44.2, 37.1, 51.9}

I would like a answer to the following question: For instance:
You have a class called Main. This class created a object of another class called Math.
Class Math has a method called Calculate()
Class Main wants to call this method Calculate().
What kind of modifier should I use for the method Calculate()? I always used public but now I am not so sure... Friend seems to be working as well. What is the best way to do this?

I have a logging class that stores entries in a datatable dt. I then use SQLBULKCOPY to write that dt out to a sql table. Basic stuff. Problem is, I'd like to only call SQLBULKCOPY when there's say 50 entries in the dt. The problem is, what if I'm done (either intentionally or not, like if the code block that's using the log class throws an exception) with the logging object and there are still 15 rows in the dt?
