Class Diagram - Called Control Fields Not Object In The Class Diagram ?Nov 11, 2011
if I put controls on form1 like button,textbox....etcwhy called this control fields not object in the class diagram ?
if I put controls on form1 like button,textbox....etcwhy called this control fields not object in the class diagram ?
I have a solution made up of several projects. Everything is properly referenced, the solution builds and runs. Now, when "view class diagram" for this class, it doesn't show any fields. It shows "dmxProgram" as a property, but it doesn't show any of the non-property private fields. Therefore I can't add associations to my class diagram for those fields that do not appear.
I'm wondering why I can't create an association from a class to a static class in the class diagram editor of VS. Any reason for this?View 1 Replies View Related
I have built a class diagram for a proram i am building in vb, and i need some help to enhance it.The program description:"Modeling Car Parking System Modeling Car Parking System (MCPS) is the software that manages a parking for cars. The dedicated employees in that parking will use this system to control the parking. This software will facilitate the work in the parking and covers most activities performed, such as booking, cashing, and organizing. In the following, we will provide a comprehensive description of the parking (the scope of the system) followed by a description of the system with the functions that will be performed.
The Parking (The scope of the system)The parking consists of two floors, with a capacity of three hundred car places, and opens 24 hours all the weekï¿½s days. It has two main control stations; one is located at the entrance gate, and managed by an employee whose main functions are entering data to the system, then providing a receipt to the driver, and the other is located at the exit gate (cashier station), managed by an employee whose main functions are checking the receipt, entering data to the system, cashing, and providing an invoice.
The parking has three barriers, two main barriers are placed at the entrance and exit gates, and the third one is located at the second floorï¿½s gate. They are controlled by using a remote control.When a driver wants to park his car, he has to drive it to the entrance where an employee (receptionist) will enter the car plate number to the system, then prints out a receipt to the driver. This receipt will contain information such as, the car plate number and the entry time. After that, the receptionist will open the barrier to allow the car enters the parking.
Inside the parking, the second floor will be kept empty (closed by the barrier) until the first floor will be full. When the first floor becomes full, the employee will open the barrier to allow the cars to park in the second floor. A driver can park his car in any vacant place in the available floor.When a driver wants to leave the parking, he drives his car to the exit gate and presents the receipt to the employee in the cashier station, who in turn, will check if the number recorded in this receipt (at the entrance) is similar to the real plate number of the car. After that, the employee will enter that number to the system, take the money, provide an invoice to the driver, and finally, open the barrier to allow the car leaves the parking.The list price in the parking, declares that parking a car for an hour costs 3850 LBP, and each extra parking hour will cost 3000 LBP.
Description of the System :The system will operate 24 hours, and will perform the tasks related to the work in the parking. The following scenario will explain what we mean by ï¿½will perform the tasksï¿½ in the parking.
At the entrance gate, the employee will enter the car plate number to the system as a (driver ID), and select the available floor which is in service from a menu. The system, in its turn, will store these data and additional data such as the time entered, and then issues a receipt including information such as driver ID, entry time, date, and the available floor reference.
At the exit gate, the employee will enter the car plate number (driver ID) to the system which will generate the data related to it, and prints out an invoice including the current time, date, total parking time, and the total amount of money (parking fee); since the parking fee and the duration will automatically be calculated and displayed by the system.
In addition to the tasks which the system will achieve at the entrance and exit gates, it also will provide statistical information such as the total count of cars that exist in the parking at any time, and the number of the vacant or busy parking lots (car places) in each available floor. Also, the simulation which will be part of the system will play a role in managing the parking since it will show an up to date comprehensive scheme of the parking.
The graphical simulation of the car movement flow When a car will enter the parking, and after an employee has implemented all the tasks associated by the entrance such as entering the car plate number, and selecting the available floor, the system will issue a receipt and automatically will lead the user (employee) to the simulation part. The simulation part is a form that contains cars and parking lots as graphical components, when a user click such a button ï¿½Drive-in a carï¿½ a car will move to occupy an available empty parking lot.
When a car will exit the parking, and after an employee has implemented all the tasks associated by the exit gate such as entering the car plate number, the system will issue a receipt and automatically will lead the user (an employee) again to the simulation part. When a user clicks such a button ï¿½Drive-out a carï¿½, the car will leave to parking lot was occupied.

I want to draw a software Function Diagram which show the calling relationships between functions in my VB.Net project. Like which function calls which function and what the called function does... I have look through VISIO couple times and can't know find anything I like. What type of diagram should I use? Which template should I use in VISIO?View 2 Replies View Related
this is more of a organizational question rather than a technical one. As your project grows and has more and more forms, objects and classes, how does one keep an overview?
Is there an application available which allows you to graphically organize the relationships between forms in a diagram? An "organigram" for your project?

Need to show visio diagram on .net FORM, and need to be able to click on the shapes. Thats it. no creation, no stencils, no editing. Basicly just catch the click event from axDrawingControl.I'm having a "very" hard time to dig trough the visio DOM, disabling all of the functions, tool bars, menus..I basically will ever need a view-only diagram. So, to all the interop gurus out there, point me in the right direction please..I have the SDK, its (crap) not very useful in my case.

I'm upgrading to VB2008 from VB6 and have noticed that when drawing a small diagram on the screen it is much slower. In VB6 is is drawn 'instantly' in VB2008, 34 lines, 5 arcs and 15 text items are taking 112000,000 ticks to draw- I can see it being drawn line by line. The codes contains the code to draw the diagram and some minor calculations to determine what to draw. If I just draw 4 lines directly it takes 80,000 ticks which looks 'instant'. It looks as if the calculations are slowing it down. Is there some reason for this, is there a box I have not ticked that makes it slow?View 7 Replies View Related
I have a requirement to show genealogy diagram to user based on readily available data. Our existing database is as follows
1- Every person has unique ID
2- Relation field's has id of respective persons based on relationship like Father, Mother, Spouse etc.
I wish to build and display a simple diagram that is built from data entered by the user. Because I can't post a picture of the types of diagrams here I'll use the following example. Image a picture of a house as a child might draw it a large square, with a triangle for a roof, a rectangle for a door, and two smaller squares for windows. Now I want to build an application that lets the user enter data and change that drawing according. For example, by entering the length and height of the house the size changes, change the number of windows, size of the door or height of the roof.
Now this may seem like a useless application but keep in mind the house is just an example the real purpose is different but should be as simply drawn. I'm looking for suggestions on make this work. Should I use a paint? or is something like this better done with a tie into the Visio references?
I have a base class called PageBase and then a derived class TestPage that inherits from PageBase. In PageBase I have overridden the OnInit() and when it is called and I inspect the value of 'Me', it is of the type of the derived class and not the base class. My question is how does inheritance really work? For instance, when instantiating TestPage does an instance of PageBase get created too?
Here is my code;
Partial Public Class TestPage
Public Sub New()
I am utilizing a centralized class object that needs to call another class object. The program itself will do something like the following

I'm currently refactoring an old Visual Basic DLL (VB.Net), which stores all of its data in one module called Globaldefinitions as public fields. There are about 200 fields, referenced thousands of times all around the code:
Public Module Globaldefinitons
Public a As Short
Public zz10 As Double
I need to change the module into a class with non-shared fields. This means, each and every of these thousands of references needs to reference the instance of that class:
globalDefinitionsInstance.a = 5
How do I go about this efficiently?
Regular expressions operating on the source fall flat. Refactoring tools like Re-Sharper or CodeRush don't seem to offer this functionality. Visual Studio 2010 cannot do it automatically either.
ReadOnly name As String
Public Sub New(name As String, dependentUpon As Foo)
Me.name = name
The output of New Bar() is:
Dependent created. Dependent upon nothing.
Independent created. Dependent upon nothing.
It seems fields are initialized in the same order as they appear in the source code, which (a) leads to an unexpected result, and (b) seems a little puzzling, given that one is normally not permitted to read from uninitialized variables in .NET, yet that seems to be working fine above.I would've expected VB.NET to be smart enough to initialize referenced fields first, and only then those that reference it; i.e. I'd have liked to see this output instead:
Independent created. Dependent upon nothing.
Dependent created. Dependent upon Independent.
how to get VB.NET to behave like that instead, without simply having to swap the declaration order of dependent and independent inside class Bar?
I have some classes, BsfciFile and StudyFlashCard. Bsfci is the extension to which I save my set of flashcards in an INI format. I am currently working to transform my code from using Windows API calls to access the INI to using a IniFile class that I found on the internet. I would like the BsfciFile to have a Array of StudyFlashCard objects, but I would like the StudyFlashCard class to use the IniFile class object contained in the BsfciFile class. I can pass the IniFile from the BsfciFile class to the constructor for the StudyFlashCard class, but I want it to modify the same IniFile as the BsfciFile class has later on.

I have a class in which some of the fields are also classes.
I can put values in the "normal" properties, but in the others when o try to assign values it gives the: "Object reference not set to an instance of an object"
But the code compiles fine.
dados_Defenicao = New ServiceReference1.draftClaimEntryDefinition
dados_Defenicao.arCode = "123"
dados_Defenicao.claimMarket.warrantyType = "w" - Here it gives the error
If we are within the derived class then ofcource we can use MyBase keyword to access base class's object reference . That's fine , how can we take that base class's object reference outside that derived class's definition.My following code will explain what i want . Actually that is giving error right now, but it is explaining my requirement .
Public Class Base
Public x As String
Actually there is error in ReadOnly Property BaseReference's Getter . Error is "Error 1 'MyBase' must be followed by '.' and an identifier. " how can i get base class object reference in Main method ?

Two files - TestClass.vb, myForm.vb
TestClass.vb looks as follows:
Public Class TestClass
Private myClassThread As New Thread(AddressOf StartMyClassThread)
The result:Application runs, no errors or exceptions.Displayed is the listbox and the Start button.I press the start button and a msgbox says "Not Invoked" as expected and upon clicking OK to that msgbox "Start Button Pressed" is added to the Output listbox control.Immediately following that the msgbox pops up again and says "Not Invoked". I was expecting "Invoked" as a separate thread is trying to use the Output listbox control.Of course this results in the Output.Items.Add being attempted which results in no visible result as the thread is not allowed to directly update the UI control.

Public Class ScaryAnimal
Public iScariness as int32 ' 0-100, how scary is it?
