Randomizing - Code That Reads In Lines Of Tabbed Text
Jan 4, 2010
I have a piece of code that reads in lines of tabbed text. It is a game of who wants to be a millionaire. What I would like to do is get the game to incorporate random questioning.
The format of the text file is as follows:
Which record company did the Beatles create? (tab)Apple Records (tab)Sony (tab)BMG (tab)LiteFM (tab)Apple Records (tab) Which has the highest mountain? (tab)Mars (tab)Ireland (tab)Iceland (tab)America (tab)Mars(tab) With a set amount of lines. I want the program to choose each question randomly and not to repeat the question. I'm not sure how to incorporate it into the code.

I have a hardware which sends out packets containing 17 bytes to the comport in bursts of 3. the little test VB that I have written receives and displays the bytes in a line of 17 bytes long and works fine until it gets to around 170th packet, then it starts to mix up (looks like shifting the data left) the bytes shift mostly by one digit sometimes by two. then it will continue to give almost a packet correct and a packet shifted for about 50 packets. Then it will correct itself for a long while, but then the speed at which it receives drops. All the packets are sent 3 times, and before things go wrong (within the first 170 packets) the packet counter shows that it receives 3 packet each time but after the problem it goes to 2 packet per burst and then to one.
If i close my VB monitoring program say at packet 165 and immediately open it again, it wont go wrong for another 170 packets, this points the finger at VB. I have check my hardware, there is no problem with that.The program reads port - waits for 17 bytes - once 17 has been received it will go and buffer the packet in an array. In fact they are 2 arrays but printing fro either results in the same problem.I have tried whatever i could think of but to no avail, i am wondering if some kind of house keeping needs to be done to clear something... I am sorry the program is a bit messy but I have been making many changes to find out what the problem is - my code below:[code]

I have built a Tabbed WebBrowser using various pieces of code from the internet. I am trying to create a button that will allow me to enlarge the page too 120%. I used some code on a normal WebBrowser page and it works OK. But this same code will not work on a Tabbed WebBrowser because of the ActiveX. This is the code I used on both browsers, as I said, it works ok in normal webbrowser, but not tabbed webbrowser. I am using Visual Studio 2010
Private Enum ExecOpt
'A few options for what we want to do, using ActiveX
'This option will just carry out the default action

I need to write a code that reads off a value from a another system's screen and compares with fixed value in .net 2005. The code should read all 24 lines of data from the screen and match to see if it is equal to the fixed value. What I have so far is:
Code:
Dim ObjScreen(6) As Object
Private ObjOIA_Area(6) As Object
Private OIA_Area As Object
[code].....
However the code is not working. and get an error. How can you select all or read line by line to get your desired result....

I have written a simple script to get a bunch of lines from a text file (they will be filenames eventually) which are split by new lines and puts each one into an array..
Dim ary() As String
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
If My.Computer.FileSystem.FileExists("C:MenuFiles.txt") Then
[code]....
The only thing I can do for now is either use the substring function to remove the first character from all array values after 0 but I don't like that because it's messy and what if the split "works" as I want it to one one of the lines and knocks of the first character when I don't want it to.

I am trying to update someonelse code, the attached code reads from a unicode txt files and compares a string of "Department_Name |Division_Name|Position_Name|Job_Name" with a db field called "ident_org" in org tbl. Since it is a bad design, I need the code to check a combination of ""Department_Code|Division_Name|Job_Code" against db and get the value of uid_org (unique key). Then if key exists then update that specific row(s) else insert the combination of "Department_Name|Division_Name|Position_Name|Job_Name" into db.[code]....

I am writing an app that reads from the com port, filters the data, then writes to the text box, then immediately starts over. This all takes place in an endless " do while" loop within the "start" button code. I also have a end button too which closes the com port and ends the program. Some other buttons are present also to change the filter settings.Problem is when I click start, data is logged, but none of the other buttons work. Also some of the text boxes are "see through" and dont look like thy have updated with the rest of the form.

I'm trying to create a program which reads a text file into an array.
[Code]...
But that's just silly so how can I fix this? Lines isn't being assigned a null value it's being assigned the first line of text in the file which has text in it so I'm confused.

I am working on a project that involes reading an Excel file, picking through it, then creating a flat CSV file. One of the the data elements I am picking up is a 9 character string that may be numeric, or contain one or more alpha chatacters. Excel has a nasty habit of converting long numerics to scientific notaion. I can overcome this by converting the "general" string to "TEXT".
However, there is one instance where I can not get the function to work...the string is "90333E108" ( the CUSIP for USU). Regardless, the text string is saved properly into the CSV file. When opened in a text editor, it reads correctly.
When opened with Excel, it is in scientific notation. Changing the field to "text" from "scientific" still displays "9.03E+112".
how to create an csv file that Excel will open and read correctly?
You can test this by creating an Excel workbook, format all cells as TEXT and add the following data:
90333E108
123

I'm having problem with our germany customers whose operating system uses dot as thousand separator and comma as decimal point.I have an application which reads some text from an Access database, parse it into data and display on a datagridview,the program also needs to write the data into another file as input to another application. right now, it seems when my application parses doubles (say 0.2500),germany os will always return everything except the decimal dot(so 0.2500 becomes 2500),and that just messed up the whole process...so my question is, how can we detect the locale of the windows and parse the doubles correctly?

Im trying to come up with a do while statement that reads through a text file till the end while pulling out 3 different matched items, then writing those matched items to ascending spots in an excel file, and then creating a bar graph according to the saved data. Sounds complicated but...I have the program reading the text file, pulling out the first iteration of all three, writing them to an excel file, and I have it even graphing them the way I want it to. The only thing I havent done before (and which is probably the easiest), is creating the do while statement so it keeps searching line to line for the three interactions of what im looking for and writing them to ascending spots in the excel file.
Right now my code works like this, which is perfect for pulling out the first 3 and creating a graph, I just inserting a do while and a rowindex + 1 variable.
vb Dim alines() = System.IO.File.ReadAllLines("C:deviceinfo.txt")
Dim amatch As String
Dim muvalue As String
[CODE]................
I have a feeling in order to pull this off, I do not want to use the, "ReadAllLines" option and possibly want to put the text into an array.
And do something like: if lines.count > 0
But im not familiar with how arrays work in VB, and more specifically what the syntax is. The other tricky thing I am trying to add is an if statement that adds to a variable (such as i) everytime a line is added to excel so the program will write to ascending lines. I was trying to have the it work with the do while statement but pretty soon realized that if I did: i = i +1. Everytime it went through the loop then the data was going to be on random lines corresponding to their place in the text.

I was just wondering how I could send commands to a tabbed browser. Such as navigation. I know of webbrowser1.navigate, but that will not work with the tabbed browser. I would also like to use an commands to automatically login. But I am not sure how I could do that in a tabbed browser either. Webbrowser1.document.getelementbyid does not work for this.

I have a text file containing lines of data (File 1). I need to delete all the lines in another text file (File 2), which are found in file 1.So I could read file 2 line by line. And then once the line has been read, read file 1 line by line to search for a match. But that's going to be painfully slow.Or I could read file 2 into memory. And then read file 1 line by line and REPLACE the lines in file 2 with nothing, therefore deleting them. File 2 could be 100 mb, so I'm not sure about reading it all into memory.

Hi, I'm working on a program that reads text entered into a textbox and creates a list of items by separating entries by commas. Everything is working fine, except, because I am using an array to store the items in the list, I have a limited number of entries. This is only a problem because, as it is written currently, each comma counts as an individual entry. Therefore, users can enter ",,," for example, and it would use up 3 places in the array.
I'm looking for a way to check to make sure there is text after the comma before adding an entry. I've attempted to use the .substring command to check the character after, which works until it gets to the last character. Because there is no character after that, it will give an error.
Here is my code for extra clarity:
Public Class frmMain
Dim intCounter As Integer 'Stores the # of commas in the string
Dim Messages(49) As MessageProperties

I have the following code, my employer wants me to reduce the lines of code to do the job.
Private Function getClientSheetNames(Optional ByVal type As String = "all") As List(Of String)
If type = "extra" Then
Return clientExtraSheetNames
End If
[code].....
I am not able to make out how can I cut the lines and have the same functionality !Are there any vb.net construct that can reduce the loc by better implementation ?Can I have a new function to be called from getClientSheetNames and getDevSheetNames that will can implement code resue ?Can I introduce polymorphism in a possible new function ?
