View 7 RepliesI 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 week�s 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 floor�s 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 �will perform the tasks� 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 �Drive-in a car� 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 �Drive-out a car�, the car will leave to parking lot was occupied.

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. Seems like a lot of resources wasted and lots of hustle for view only.
View 3 RepliesI'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 RepliesI 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.

View 3 RepliesI 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?

View 10 RepliesI want to make an numerical integration method with takes in an analytic function and integrate it over a specific interval. For the numerical integration procedure I want to use some procedures in nr.com. The problem is that these are programmed in C++ and they uses functors to pass a function to the integration method. How can I do this in VB 2010?
I want to initialize the function (i.e. set a=1,b=0 for function y(x)=a*x+b) and then pass the function to the integration method. Then when the integration method call the function it only calls the function with one parameter (i.e. x since a,b is already set)
What is the best way to do this in VB2010?I want to make a general integration method where I can pass any single valued function and integration limits.
I have just started using VB, and from what I have found so far it seems like the tools you have is
- to us a delegate for the function
- to use a lambda expression for the function
- send a pointer/adressOf
- to create a function class/structure and submit this to the function
As for now I am most inclined to create a function-class. But I am not really sure how.F.ex. I make different classes for each "uniqe function" I want to integrate, but how can I pass them to the integration function when I need to specify the argument type in the integration-function-call?This seems like a basic problem which applies to many Math operations, so I think it would be very useful to clarify this.
We can add class in class diagram and voila the code show up. What about the other way around. Say we already have a class. Can we add that to class diagrams?

i wanted to ask how to make picturebox1 ,to which functions are already assigned, perform the same function as picturebox2 ,to which no functions are assigned.For example:I have already made picturebox1 and have assigned it alot of function like when play button is pressed then picturebox1.visible = true and when we press pause button picturebox1.visible = false. So now i decided to make a theme and have to remove the picturebox1 and want to allow the picturebox2 to havefunction of picturebox1.But when i disable the theme the function of picturebox1 should go back to picturebox1.

View 1 RepliesI'm currently working with a client's VB.Net code, which was developed for them by a small development shop a few years ago and which they purchased and have been maintaining and uprgrading since. This client's primary developer is out on indefinite (likely permanent) medical leave and I'm now filling in until they bring in a full timer (as I'm a contractor here). My current task is to add some functionality to a the VB.Net code they purchased. I'm finding practices and techniques in the code that absolutely baffle me and can't make the code do what I want. I'm starting to wonder if it's me and was hoping to get some thoughts on the code I've encountered.
For example: Setting a variable to accept the result of a function by calling the function with many parameters, clearing the parameters in the function, setting them to some value, calling another function with those new values, then never using the values returned by the functions. I'll add a code snippet in the first comment since this is already getting long.
