Asp.net - .net - RsData / Cleaning Up Code?
Mar 21, 2012I have a question regarding VB.net and the use of rsData connections to an SQL database.Basically we have a few inline pages that will display course information of courses that my institution runs. The code will connect to an SQL DB and pull through live data directly in the following format.
html += "<tr><td>" & rsData("M_Start") & "</td><td>" & rsData("WEEKS") & "</td><td>" & rsData("DAYSTIME") & "</td></tr>"
Now I was wondering if people would suggest pulling directly from an open DB connection or map the RsData results to strings? All data connections open and close after they have done their required portions and we have around 5 different procedures that occur within the page.
Cleaning And Sorting Out Game
Nov 21, 2011I've been making a game using a Console Application as the main window, for the it. The game requires you to make the right choices in a mini Hacking adventure, but I'm rather stuck in an area where the player is required to enter the name of the file they would send and the program does not recognize the right one, also I was wondering how I could tidy up my code as It seems to be growing at a unnecessary rate.[code]
View 6 RepliesCleaning Up Code With Functions?
Nov 28, 2010I am just starting out with a practice VB project which involves selling donuts and coffee. I have written out the code which the program works but the code is very messy. This program contains functions and radio buttons to calculate a subtotal, tax, and total due. There are four variety of donuts in Group Box 1 listed as: Glazed at .65 each, Sugar at .65 each, Chocolate at .85 each, and Filled at $1.00.
The coffee choices in Group Box 2 are listed as: None at 0.00, Regular at $1.85, and Capuchino at $2.50 each.I want the cashier to be able to select a radio button to choose between the donut choice in group box 1 and then choose one coffee choice in group box 2. A textbox calculates the subtotal, a textbox calculates a tax of 3%, and a textbox calculates the total due adding the subtotal and tax.
Everything works fine but Ias I said before it is quite messy which I keep making it worst.I need to write one function to calculate the donut, one function to calculate the coffee, and one function to calculate the sales tax. Then I need a sub procedure to clear the subtotal, sales tax, and total due amounts when a radio button is clicked.I have been working on this for the past month ,code I have so far:
Class frmMain
Private Sub btnExit_Click(ByVal sender As Object, ByVal e As System.EventArgs) Handles btnExit.Click

Cleaning Up Open Programs
Sep 11, 2009first, what is the base minimum that windows needs open to run... ex. svchost.exe, explorer, etc.
Second. is there an easier way to close all programs except the ones i want to stay open, i want to keep the needed basics open and my program, which will open other programs, but i want to make sure nothing else is running so that things will go as smoothly and as fast as possible. I just don't want to manually check what processes need killed and place them in the program one by one, i want to kill all but a few.
Extra credit... stopping all unneeded windows services would be nice too, but that would probably be too long of a process to worry about, and not really worth it considering the benefit of speed it would give.

VS 2008 Cleaning Up A Nested For Each-loop?
Dec 3, 2009I'm comparing a temporary table to an another table, to check for changes in the cells. The way I'm doing it, is that I'm using three loops; one to loop trough the temporary, one to loop trough the other table and a last one to loop trough each column. Here's the
vb.net
For Each row As DataRowView In View
For Each drow As DataRowView In view2

"emitid" is the column I use as a reference to be sure that I'm comparing the correct rows, and the column order will always be the same in both tables.
Reusing And Cleaning Up User.config Files?
Nov 11, 2010Not sure if this has been asked before (couldn't find an answer), but is there a way to reuse a user.config file from a previous version of the application? For example a user.config file is stored in:
C:UsersJohnnyAppDataLocalCompanyApplicationName.exe_Url_wxcnyrmstqy3oj1qwckdjq3gjqkq4fel1.0.0.0user.config After a new version is installed it gets stored in:
C:UsersJohnnyAppDataLocalCompanyApplicationName.exe_Url_wglmejvw01nagu5t1y5yl12chynjomny1.0.0.1user.config The user then has to enter all settings again, even if the new version does not save more settings. An other problem is that although the user.config file is very small, it does get messy after a while when newer versions of the application get installed. Is there a way to clean up the unused user.config files and their folders?
It's the same problem with System.Windows.Forms.Application.LocalUserAppDataPath, that I'd like to use to save other files (containing Listview data), which points to:
C:UsersJohnnyAppDataLocalCompanyApplication1.0.0.0 The Listview data and other files created by the app can't be used anymore.This can be solved by getting the user's appdata folder with Environment.GetFolderPath(Environment.SpecialFolder.ApplicationData) and creating a new folder there with the name of the application. But this means there's one folder where the application is installed (user can choose this folder in the installer), one folder to save my own files to and one folder where VB stores the user.config file.
Can something be done about this "mess" or is this just something I have to live with?

Extract String From String When Only Beginning Of String?
Aug 12, 2011Basically I have a webresponse stream:dim lol as string = readstream.tostring there is a lot of information within the string but only one link starting with http: located near the end of the string - however there is no constant character point where I can start... (i.e. 38)
I want to extract the link from the string i.e. dog cat plane car [URL]..that is approximately how it looks above - words and url substituted I want to just extract [URL]..I had an idea of parsing the string from http: to the end Then after that splitting the string up again to remove the }], however it does not return anything

Asp.net - Decimal.parse Fails For Currency String Created With String.Format?
Apr 5, 2011I have a field that I display via: String.Format({0:c},amount) This produces the string "$28.28" However, when I try to convert back to a decimal amount, I get an incorrect format exception: amount = Decimal.Parse(amount.Text, NumberStyles.Currency) I also tried it with NumberStyles.AllowCurrencySymbol with the same results. I verified that the value in amount.Text is "$28.28". Am I missing something? Shouldn't these two operations use the same currency symbol and formats?

Options To The User In A Menu - Create Sub-string - Replace A Word In The String
Feb 28, 2010Problem: Your task is to take input from the user in string and give the following options to the user in a menu.
1- Find a String
2- Create sub-string
3- Erase a portion of a sting
4- Replace a word in the string
5- Count number of words and characters in the string without spaces.
6- Capitalize first character of each new sentence and convert the rest
of the characters to lower case.
7- Sort all the words in alphabetical order. (Use Bubble sort algorithm to perform sorting).
To perform all the above mentioned tasks you can only use pointers. Create a function to perform every task.
