.net - How Long Dose It Take To Analysis, Design And Program A CMS Using ASP.NET
Oct 4, 2009
I intend to choose developing a Web Content Management System using asp.net with VB.net 2008 but I'm not sure about how long it takes to program such system. Is 4 months enough for developing such system? This 4 months is the duration of this semester and Includes about two months for analysis and design and the rest is left for implementation.
With this assignment, you are provided with an incomplete object-oriented implementation of the GAME MANIA software system based on Visual Basic 2008. The specification and the subsequent modelling are explained in a case study titled Game Mania: GAME AND GAME CONSOLE RENTAL STORE.
An implementation of the following classes are made available as the basis of your development work:
Note that the user interface provided is very basic. You need to change it, as you feel appropriate so that it will reflect the required functionality. For example, in the present implementation version, no provisions were made in the user interface for querying and handling fines associated with late returns.Providing this aspect in the user interface might be necessary as part of handling renting of games and game consoles.
When running code analysis on my project, I receive the following message:
CA1051 : Microsoft.Design : Because field 'ClassName.VarName' is visible outside of its declaring type, change its accessibility to private and add a property, with the same accessibility as the field has currently, to provide access to it.
Public VarName As String to this:Public Property VarName As String
I don't understand why the Property keyword is so important in this particular case. Can anyone provide an explanation as to why changing this member to a Property makes a significant difference to code analysis?
I am writing a VB.NET Windows Application which takes numeric user-input and performs a complicated calculation, yielding many numeric output variables. Previously, I wrote a similar program in VB6, which output the results to a rich text box using fixed-width font in order to organize data in columns and used asterisks to delineate table areas and section borders. I then used the printer object for printing the output. This method was very archaic and difficult to modify when changes were necessary.
I have made a textbox, which restricts character use to numbers and periods only. Nice, but now I cant enter backspace to amend any data typed in my textbox.
Private Sub TextBox10_KeyPress(ByVal sender As Object, ByVal e As System.Windows.Forms.KeyPressEventArgs) Handles TextBox10.KeyPress Dim allowedChars As String = "1234567890." If allowedChars.IndexOf(e.KeyChar) = -1 Then
I would like to know if there is a way to see how long a program runs. I have one that takes a very long time to run, which is not the problem. I start it and go to bed or leave for the day. When I come back it has finished. I do know it takes hours. Is there a way to find out how long it does take to run give or take a couple of minutes?
I got a problem with my setup I had set the prerequiest download property to download from the same location. Now i am in a problem that my setup dose not check for the already installed prerequiest it starts the prerequiest installation no mater if they are installed or not. after the installation of these prerequiest it says to restart the computer and after restart it starts the prerequiest setup again.
I have a problem with my (aspx.vb, aspx) program. Since my vb program require more than a day to make some data analysis. however, the page always run a long period(one hours exactly) will be downed and become cant display the page. i am wondering is it related to dns error?
I have written a program that searches a bunch of urls and pulls out information that I need. The program works to an extent. Everything codewise works, but it seems like I did a sloppy job of pulling the code together. After about 10 minutes of running, the program just becomes unresponsive and I have to close it through task manager. I've seen it range from 100k to 350k in memory useage. It also uses about 80%+ cpu usage at all times. I hope someone might be able to see something that I forgot or did wrong as the program is meant to run almost full time, executing parts of code on certain days/times.
Dim con As New SqlClient.SqlConnection Dim strCon As String = "Data Source=server;Initial Catalog=database;Integrated Security=True" con.ConnectionString = strCon
I am trying to execute a program with switches that ends up with a shortcut being too long and exceeds the 260 character limit for shortcuts in windows XP:
Is there a easer way of coding in stead of wrighting long long paragraphs like this in one line [code]All of this is on one line and i got lots of info to put down.."The game will begin on your 16th birthday with your mother waking you up. Today you are to go to the castle for the first time. Leave your bed and open your dresser for a Strength Seed. "
I'm currently trying to write a football simulator but am having issues with the computer becoming unresponsive. There are long lines of code (several thousand lines) that are executed over and over as one run of the code is equivalent to one second of game time. While the game is setup to be like Football Manager where you watch the game live, there will also be cases where the entire game is simulated without you watching. When doing a full sim of a game, I just have a loop which executes the code block 7200 times (games go for two hour roughly).
At the moment this takes about a minute but even when I get it down to the desired 5-10 seconds or so, I dislike the fact that the computer becomes completely unresponsive during this time. In a round there are 9 games and you'll be simulating without watching 8 of them. You're looking at 1-2 minutes of simulation time or possibly more. I can't have a loading screen that long! How can I program the game so it runs these simulations yet the game still remains responsive? It'd be fine if the user could muck around in the menus and stuff while the simulation runs.
I am making a program that loads, edits and saves 5000 rows x 100 columns of data. The data is stored in a datagridview. I use these commands to write the file:
dim z as integer dim z1 as integer fileopen(1,"c:drawermyfile.txt",openmode.output) for z=0 to datagridview1.rows.count-1 [Code] .....
Every time I issue this command the whole program freezes until the computer is done writing the file. Is there some way I can get it to write this file without freezing up the program? Or, perhaps a better way to write this large data file?
I am running a test program for VB.NET, and it will simply crunch a million numbers in for loop. I've linked a variable implying the progress of the for loop with the progress bar, but it seems that when I run the program, the progress bar does not update itself. The bar itself has only value 0-100 as input (as stated in the document) and I've tested it without using the for loop, and it works.
I have a program that requires a string. The string is 20 characters long. The string also have to be split into 2 words the first word is 12 characters and the second is 8. If the strings is not 20 characters long I get an error. I wanted to know how can I get the program to start back over and let me enter another 2 more words if the string is not 20 characters long. At the moment after I get the string is not 20 characters long error it continues to read the rest of the program but I want it to stop after an error and let me start over from the beginning.
i have built a DB app using vs2010Beta2 + an Access DB .mdb file for my customers the save bnt work s ok, but when i close the app i get an error message come up saying :- Dynamic SQL generation for the UpdateCommand is not supported against a SelectCommand that dose not return any key column information.i have no errors repoted in the error window at the bottom and all runs well untill frm_closing,below is the code in my form closing event. below that is the code for the btnSave event
Private Sub frmMainCustomerDetails_FormClosing(ByVal sender As Object, ByVal e As System.Windows.Forms.FormClosingEventArgs) Handles Me.FormClosing If MyState = "Edit" Or MyState = "Add" Then
I've noticed that when I save a newly scripted program and attempt to open it after I close Visual Studio 2008, it no longer shows the layout/design of the program...how would I go about configuring it so it looks the same as before I closed visual studio?
In Visual Studio 2008 I am using :Private Declare Function BlockInput Lib "user32" (ByVal fBlock As Long) As Long To stop input from occuring during a search-replace operation.
BlockInput(True) ' do not allow input during search and destroy Dim cursorIcon As Cursor cursorIcon = Cursor Cursor.Current = Cursors.WaitCursor
Then setting it to false at the end of the operation. It did not work, so I thought maybe it was because I was calling it from a child window, so I created a function in the mainwindow, and ran it like this:
FrmMain.BlockFrmMainInput()With these functions is the Main window:
[Code]...
It did not solve the problem. I thought maybe it was because I was running under the debugger, so I tried compiling and running it debugger-free, but that did not do any better. I am still getting input when I double-click the mouse on either form.
We have two systems, one is created in VB.Net 2003 and the other is created in VB6. Both systems are client/server desktop application system. There is a requirement that we need to send and response data to each systems. The data will come as result of process of each system and then transfer it to the other system. These is formatted in a message format. Is it likely to become socket programming? how can I send and response data between servers?
I'm supposed to design this program in ConsoleApplication about Phone Numbers:
You are writing a program and you need to store telephone numbers. You'd like to be user-friendly, and let the users enter their telephone number in whatever format they like with parentheses and dashes, so long as they enter 10 digits. Assume that they won't enter any other characters. The user will only enter ( ) - spaces and numbers.So, these would all be valid inputs
build a program using vb to simulate an (Alasmpelr with the pass1), i attempt to do the program and the program work when i use small Source Code and it's succeeded, but when i use the software with large Source Code it does not succeed i tried repeatedly to do, but I stopped at many points I did not know how can i solve it
I have opened an existing project and made changes in the design mode. (For example, I added a new button.) But when I tested the program using Start Debugger, none of my changes showed up.
I'm reading data from the microphone and want to perform some analysis on it. I'm attempting to generate a spectrum analyser something like this:
What I have at the moment is this:My understanding is that I need to perform a Fourier analysis - a Fast Fourier Transform ? - to extract the component frequencies and their amplitudes.
Can someone confirm my understanding is correct and exactly what type of Fourier transform I need to apply?
At the moment, I'm getting frames containing 4k samples from the mic (using NAudio). The buffer I've got is 16bits/sample (Signed Short). For reference, the above plot shows approx half a frame I'm coding in VB so any .Net libraries/examples (preferably on NuGet) would be of most use. I believe implementations vary considerably so the less I have to massage my data, the better.
