VS 2008 Enum And Radio Boxes-passing Info To Business Class?

Jan 29, 2011

I'm trying to pass data from the main form to a business class form for calculation.I have 3 types of cars and I can't get the code right to pass that to the business form. It seems correct to me, but obviously, it's not.This is the code for the calculate button, I can't figure out why its telling me that CarSize is not a member of the business form when I have it in the Enum statement at the top. I'm going by what the book says and this appears right according to it.

Dim CarTypeInteger As Integer
'determine the car size from radio buttons
If LuxuryRadioButton.Checked Then

[code]....

In the book it says to specify the class name when declaring the enum on the business form. So to me it looks like it should be -RentalRate.CarSize.Luxury The error I have is 'CarSize' is not a member of the 'ChristiansCarRentals.RentalRate'.

Passing Class Info By Value Rather Than By Reference

Apr 30, 2010

Public Class Form1
Public Contestant As New ContestantClass
Public HighScore1 As New ContestantClass
Public HighScore2 As New ContestantClass
Public HighScore3 As New ContestantClass
[Code] .....

The problem I'm having is the first time I take a value, it gets inserted in the right section. The second time I insert a value, it inserts it in the correct place AND updates the previous value I inserted with the new value. So apparently when I'm doing:
HighScore1 = Contestant
It's pointing contestant AT highscore1 rather than taking the name, company, and score from contestant and then storing it in highscore1. How I can pass that info by value rather than by reference?

Check Boxes And Radio Buttons - Value Is Not Being Updated Until I Select A Different Radio Button?

Oct 10, 2011

trying to write a simple form for calculating professor's salaries depending on their degree and position.my problem is that the when i select a check box, the value is not being updated until i select a different radio button. it probably doesn't make much sense here,

Public Class frmMain
Private Sub optLecturer_CheckedChanged(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles optLecturer.CheckedChanged[code]....

the values being assigned to my salary label are correct, but are not being updated until i select a new radio button. im not entirely sure how to get around this so that the value is updated as soon as i select the check box.here's when the program looks like:

VS 2008 - Using Check Boxes With Radio Buttons

Sep 5, 2009

I have 8 check boxes and 4 radio buttons on a child form. When the User checks a Check Box, they then select a radio button. They will do this for 1 to 8 of the check boxes. The only way I could think of to keep track of this is create 8 panels with 4 unique radio buttons in each. Then I would set the visibility to each one accordingly. This method has other logistical errors than just trying to get the design view worked out.

I was wondering if there was a way to just use the radio buttons. I thought I could set a boolean variable to keep track of each Check Box's Radio buttons. Or an integer variable. For instance, if Check Box 1 is checked and Radio Button 1 is checked then myVariable's value is 1 or whatever. Then when I actually run the app, I can check the value of the variable do do what I need. Does this sounds plausible?

VS 2008 Using ENUM Definition In Class Properties?

Jul 28, 2011

In a global module, I define a new type that can take 4 values:

enum tAction as integer
None
Update
Insert
Delete
end enum

A use this type in many places in my code to check the value stored in a variable (if MyAction = tAction.Delete then ...)

In a separate file, I define a class. One of the properties should return a value of this type:

public class XXX
private _Action as tAction
public property ClassAction() as tAction

[Code].....

This way I could check a class property in the same manner (if MyClass.ClassAction = tAction.Insert then ...)

However I get a syntax error in the property definition: 'ClassAction' cannot expose type 'Globals.tAction' outside the project through class 'XXX'

My entire program consists in a few modules, in a single project. How can I use my tAction definition in my classes?

VS 2008 - Create A Form With Radio Buttons - Text Boxes - Labels

Jun 22, 2009

I need to create a form with radio buttons, text boxes, labels, etc.. This information needs to be pulled from a database. For instance, I have a form that displays information that needs to be inputed to a database, based on what test is being done for a specific product. Each product requires different tests. So each product may or may not have the same information that needs to be inputed..

What I have done is made a database and filled a table with each product and what tests apply. I then call that database after the product has been selected for the tests. It will then fill an array for that products information for what texts boxes and labels need to be shown. I wanna take this further and have it create a form through code and align all the controls to specific spots so that it will look nice. For example I wouldn't wanna create a control and have it be cut out of the form, or have other controls overlapping others.

VS 2008 - Passing A Object Data To A Class?

Oct 5, 2010

I've got a main form (Form1.vb) where I created some controls (with the Designer).I've created a class myTextBox, inheriting from TextBox, in myTextBox.vb.In the main form, I call procedures from myTextBox. The issue is, those procedures use values from the Form controls. So the class doesn't recognise them as initialised.What's the best solution for this?I think I could pass the object itself as a parameter but doing it on each call seems a bitredundant and it thickens the code.Is there any way to access the Form1 controls and objects directly from the myTextBox.vb class?

VS 2008 - Passing Class As Argument For Function

Mar 23, 2010

VB.NET is not letting me dance with both feet, or piss with both hands. I've got one foot and one arm tied behind my back at every turn. I want to use this statement in a function:
Return CType(Formatter.Deserialize(FS), DS)
Seems doable, right?

Function ReadFileStream(ByRef FS As FileStream, ByRef DS As Object)
Dim Formatter As New BinaryFormatter
FS.Position = 0
Return CType(Formatter.Deserialize(FS), DS)
End Function

Right? I mean, CType only accepts a class name as the second argument. I can't give it an instance of a class, or it croaks. Yet if I try to pass the class name as the argument to that function:
DataInfo = ReadFileStream(FileStream1, DataStruct)

VB.NET croaks on this, too, complaining that "'DataStruct' is a type and cannot be used as an expression.". It's used as an expression by CType just fine outside of the function. Does the VB.NET legislature provide a clause that allows for a 'Type' to be passed as an argument in a function? Writing all the supporting code ten million times to deserialize a file using CType ten million times in a large application will get very complicated and tricky very quickly. It should be handled by a routine so that any cases and adjustments that come up can be dealt with in one spot.

Business Model Class Object Relationships And Communication?

May 7, 2012

I'm developing a business model for an application where I am representing physical entities. The hierarchy created from this is neat, but as I'm doing this, I'm beginning to think about things like, what properties should be included in one that may already be apart of another? Or what if some properties are expected to be in one object, but another object needs to return that value, how does it communicate that request through the hierarchical chain? And what is the best practice for this design?

[Code]...

But then I got to thinking, what if I have a ConnectionPoint entity and I want it to return which Panel it has? Should it have it's own Panel association as well? Or should there be a method/pattern for communicating the request up the chain? And again... what's typical best practice?

Getting Group Boxes To Appear When Click A Radio Button?

Nov 9, 2009

New user here using VB .Net 2008

I seem to be having trouble getting group boxes to appear when I click a radio button.

For example:

If radiobutton1.Checked Then
Groupbox1.Visible = True
Groupbox2.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If

This indeed brings up the first radio button however I have other groupboxes underneath which with the same code will not appear when the radio button is checked.

Eg:

If radiobutton2.Checked Then
Groupbox2.Visible = True
Groupbox1.Visible = False
Groupbox3.Visible = False
Groupbox4.Visible = False
End If

The second groupbox does not appear and is directly behind the first groupbox.

The .Top code doesn't seem to be working either.

Radio Buttons And Group Boxes VS10?

Mar 28, 2011

I am having trouble coming up with a way to add a selected radio button in a selected group box together.I have 3 group boxes each accessed by a checkbox within each group box there is 3 to 4 radio buttons. I would like to know how to add the selected radio buttons in each group box together and display them in a textbox by clicking a button "calculate". I believe I would have to make a global variable but I dont know where to start.

Private Sub Calculate_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Calculatebtn.Click
Dim answer As String

[code]....

I know this code is wrong but I was just trying to remember the calculate function.Is there a command that uses the selected radio button from the group boxes then I would be able to input that into my calculate button sub?
