Aug 26, 2010I need to know how to code a windows application program that will make it possible for customers to place orders online. Customers will have access to menu using a combobox,containing items available. The text file contains all menu items and the price of each item, as well as number of orders for each item. The file is created with a notepad containing 5 menu items.the first line contains the name of the item,second line contains the price and the third contains total number of orders which initially is 0. So far so good i know how to check if the file exists or not,and populating the the combobox, but ther's an instruction where i have ensure that the number of menu items does not exceed 100, and if so,should display an error message.and should validate to ensure that the total number of orders is>0,if not,re display the input box with a suitable message. Then on the save(menustrip),should write the whole textfile from arrays in memory,clear the combobox,display the message. Also has a process payment button where it should read through the arrays with a for next loop,then shouold write function called amount due,which recieves the total orders as a single data type,where the value for amount due is calculated as total orders*price.CAN SOMEONE PLEASE HELP ME OUT SINCE IM A BEGINNER IN VB2005.

Jan 29, 2009Consider the text: "The precipitation will be 2-3 cm".I need to extract the integers 2 and 3 and seperate them in order to compute their average (i.e. (2+3)/2 = 1.5).Can someone help me with a regular expression which would extract the integers 2 and 3 and seperate them. I also need to know if there is any other way to do it other than regular expression.

View 2 RepliesSort Items Before Being Written To A Text File?
Apr 18, 2012Let me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....
View 5 RepliesWrite A Text Written In Textbox To File.(a .txt)?
Mar 6, 2011I tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.
System.Runtime.InteropServices.COMException was unhandled Message: Exception from HRESULT: 0x800A0005 (CTL_E_ILLEGALFUNCTIONCALL).
It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.
File I/O And Registry :: Opening A Text File Into Multiple Text Boxes Using Loops And Arrays
May 20, 2009So I'm in the final stages of finishing a program I've been working on for nearly a year now, and this is basically my final hurdle. The Save dialogue is working beautifully, with 'flags' in order to switch it over from the regular input into text boxes to the Listbox input protocol.
However, I'm having a *** of a time getting it to take lines from the text file and put them in the proper text box. Here is an example file:
Quote:
SHOWNAME
CALLNAME
BREED
[Code]....
So with the sample file I provided above, in the textbox named callNameText would appear "SHOWNAME", and so on and so forth. With this build, I get a NullReferenceException on the "Me.Controls(strboxNames(i)).Text() = strAllText(ati)" line.
Open A File In A Hex Editor And Know That Each 2 Digits Is A Byte - Stored In Arrays ?
Dec 31, 2009I can open a file in a hex editor and know that each 2 digits is a byte, they are 8 digits in binary correct?
How are they stored in arrays in VB.NET?
So if I have:
Dim xx() as byte =
What would I put after the equals? The hex digits from the hex editor? (This is just a program I'm not going to save, basically I don't want to open files to get etc. I want to put in the bytes in the code.)

Mar 8, 2012I need to write a program to convert in a textbox a number to its roman numeral and written english equivalent. I can write everything except how to get the program to recognize the numbers and convert it into what I need it to.
This is what I have so far, and I'm not completely sure if this is even right, but I can't figure much else out. I've talked to other people who know about this and they aren't sure how to go about it, and my book isn't a big help either.
I would really appreciate any and all help than anyone could give me. I just don't know what else to do and I've been stuck here for a few days trying to learn how to do this...

Extract Certain Data From A Text File?
Jan 21, 2011To simplify what I am trying to do, let's say I have a text file with only one line of data.
The data in this case is color info for one pixel:
Color [A=255, R=255, G=200, B=128]
What I am trying to do is read the text file and extract the hex color info and save them to their own variable.
So once the code has run, these should be the contents of the three variables.
RedData = 255
GreenData = 200
BlueData = 128
I have managed to get something to work but I know the code is terrible and is incredibly slow when I try to run through hundreds of lines in a text file.

I have found the above code from the net and it works fine as I would expect. I know this because I have added a put the String StoreFile into a text box and it worked. From what I understand about the code above is that we are reading the file test.txt until we reach the end of the file and we are storing it into a string.
What I would like to do is either:
1. Search the String StoreFile until I find the text of my choice, and then extract the characters around it. See attached txt file.
For example, if I wanted to search for MNAUSD in the attached txt file, I want to grab the values on the line (highlighted in blue) and make them available to my program and ignore everything else.
"MNAUSD",UNITED STATES,US $,M,1.558850,1,1.369850,1.113500,L
I know these files are comma delimited, but I would rather use a regular expressions if possible as I have other files that are not comma delimited, so it would be ideal if I have a regular expressions to handle the search and extract
OR
2. Search the File test.txt LINE BY LINE, until I reach my search text MNAUSD and then extract the same values as above.
