Making A Program That Combines Text Files?
Mar 28, 2011
I have been tasked with making a program that combines text files.. okay.. easy enough. Problem is now I have been asked to make the same program start from the second line of the text files to get rid of headers. I am currently using StreamReader to do this but not sure how to make the reader "line feed" before it reads the data. Any help would be much appriciated. Current code below..
Private Sub BackgroundWorker2_DoWork(ByVal sender As Object, ByVal e As System.ComponentModel.DoWorkEventArgs) Handles BackgroundWorker2.DoWork
Dim writer As StreamWriter = New StreamWriter(Environ("userprofile") + "\Desktop\CombinedFile.txt")
Dim files As String() = Directory.GetFiles(TextBox1.Text)
Dim filename As String
[Code]...

Im designing a program that will read from various text files (preferably RTF files) and then put them into the RTF box in the program when a button is clicked.
Here is the portion of my code that i am referring to.
Try
Dim fileText As String = My.Computer.FileSystem.ReadAllText("c:\" & selectedHero & ".rtf")
infoDisplay.AppendText(fileText)
infoDisplay.Rtf.Format()
Catch
MsgBox("Selected Hero currently has no File with us.")
End Try
Now heres the problem. In the file i have a few pictures and its formatted and what not. I thought since its a RTF file and the Box is RTF it would auto format.... but anyways. It appears like this in the RTF Box.
{\rtf1\ansi\ansicpg1252\deff0\deflang1033{\fonttbl{\f0\fswiss\fcharset0 Arial;}}
{\*\generator Msftedit 5.41.15.1507;}\viewkind4\uc1\pard\f0\fs20{\object\objemb{\*\objclass Paint.Picture}\objw3000\objh3000{\*\objdata
[CODE]...
Ok so im not sure how i can read from a RTF file and put it in the RTF box with the right format....Ive been searching around for a while.

My "Learn Welsh" application is now near completion, I only have a few things left to add / fix then I will share it with the world. Here's a screenshot of it so far :
As you can see by the picture above, I have created a simple feature in my application to pronounce letters from a word to assist users to learn the welsh alphabet. What I would really like to do is make the program pronounce full words. I already know how to make use of the system.speech reference in vb, here is a quick sample of code:
Dim speak As System.Speech.Synthesis.SpeechSynthesizer = New System.Speech.Synthesis.SpeechSynthesizer
Dim word as string = "hello"
speak.Rate = 1
speak.Speak(word)
Now what I'm looking to do is make use of a welsh based voice and make an application like the one below:

okay so i was thinking of making a program that can take a text file filled with code so the text file would look like this
Title{Text = blah blah; text = blah blah; Title2{Text = blah blah blah; text = blah blah blah;} }
and have the program display
Title
Text = blah blah
text = blah blah
Title2

after a week of trying to find a control that combines the Treeview/Listview, a so-called TreeListView, I gave up. The ones I found are either buggy or have too many features (making them heavy).The best way for my personal needs is probably to use an ownerdrawn Listview and doing the indentation (expanding/collapsing) myself.There are a few problems:
1) I can't get the Plus/Minus images to show properly. If I expand a 'node' and collapse it, then the Plus image doesn't show. If I expand two 'nodes', then the Minus image of the first expanded 'node' becomes a Plus image again.
2) Clicking the Plus and then Minus image too fast causes weird flashing behaviour of the 'node' expading/collapsing.
3) Somehow I need to be able to update the Listview in real-time. I know I can use ListView.RedrawItems to refresh a single row, but I need some kind of structure to know which 'nodes' have been expanded. When a 'node' gets expanded, then everything below gets a different index.

I have a program where a lot of the required information for it is stored in text files. I simply read this information into large arrays. However, I don't think it's necessary to load all the information each time. Rather, it would be more efficient if I could simply search through a list of items to find the one I need and then use the data from it, or to find a similar name and use it elsewhere.
Would I be right in using a database? And is database programming done in SQL? I have a book on it telling me to use the SQL Server (IIRC), so I shouldn't be doing it in the VB.NET Express GUI?
Here's an example of what I would do:
Hex = 03 00 => dex number 003
Search in file Pokemon Dex Numbers
003 returns Bulbasaur
Check Bulbasaur base stats in the base stats file
etc
So basically I'm reusing a lot of information. I think a database would be best and it would all be internal right? I'm getting complaints about access denied to a text file (since it's stored in the program directory in the program files).
So to cap up the few questions I have:
-Databases are done in SQL and not inside the GUI?
-Databases would load internally?
-I could search a database without having to load it into like an array or something?

I use text files to hold the program data, which is loaded in to variables when the program starts. I use StreamWriter to write to the text files when they update within the program. This is fine although the writer adds a extra line when I do not want this, which causes the program to error on the next use.

I found one solution that , if change user rights manually then this problem solved.Follow these step to change your account settings.Control Panel-->User Accounts and Family Safety-->User Accounts-->Change User Account Control settings-->Never notify(Set tab to never notify).After this change need to restart system.Now can make all changes like windows XP into Windows 7.can also make changes into program files.
Its working fine, but need to make these changes manually in OS.but its not efficent solution. So if any one knows how can make these changes by coding that will nice.

I am making a program which generates a random number between 1 and 10 and when 7 appears it is suppose to tell you how many tries it took to get the number 7 and then end the application. This is the code I have used:
CODE:
This code only generates the number 7 and exits the application, each time i click the random button but i want it to show the other number it randomizes too for example 1 2 3 4 .. etc, if u dont understand, please try it, but im trying to say, when i clikc random it just says number 7 (does randomizing in background) and tells you how much tries it took but i want it to show the other number it randomized also and when 7 appears, then exit the program

On a image file (PDF), the OCR has recognised the picture and text. However on Visual Basics, how do you search for a text on this image file? The primary goal is to allow a text search (i.e POxxxxx) on all the image files (PDFs). The returns of the search will be the assciated image files where the text (i.e POxxxxx) is found on.
