Edit A Few Lines Of A Txt File And Then Save It
Jul 13, 2009
I am a beginner of VB 2005. I have a few questions on text file editing and hopefully you can point me to the right directions then I can learn more details by myself. Q1: It seems there are many ways to open a text file, such as FileOpen, StreamReader, My.Computer.FileSystem. ect.. Which one is your most frequent used?
Q2: I would like to edit a few lines of a txt file and then save it. Which one should I use?
Q3: If I want my text file can't be opened by others, how can I encrypt it.

I want to make a program where I load in a file in hex format and have a number of check boxes where if selected then certain hex values change.
So it would search for offset d5dc and change the last 4 values to 00 E1 F5 05 and then then same again for other check boxes with different offsets set to each one.

so i figured out how to save to different lines in a txt file. and how to open it. it opens fine. every label gets the right value, but when i press a "+" button it should add a 1 to it.
e.g: label1 has the value 8 after loading. i press "+" to make it 9. but instead it make label1 to 1. how should i fix that?
here's the [URL]..the code was too long for this forum so i posted the code there.

I have been using Visual Basic for about 2 weeks now so I know I am getting in over my head at this point, but times a factor. I have created a user form with around 100 User entered text boxes and pull down menus, tabbed pages etc. I can create a distributable file with no problem. However I cannot find any kind of example, tutorial, etc that will show me how to allow an end user to save the form as "enterfilenamehere.DCP" (for example) and then reopen any .dcp file created in my form application. The only examples and tutorials I can find are how to type text and save it as a txt. format. Could someone lend a complete novice some advice or point me in a good direction on where to learn about saving and opening custom file types?To clarify The user can use my form, But at this point has no way of saving and recalling what they entered in my form. It's a one time use only...not really what I want.

What im try'ing to do is when a ListBox item is selected and the value has been given with a NumericUpDown box and the ''Add to orderlist'' button is clicked that it saved it to a file called "orders.txt", not at startup but when the first order is made.
Some requirements:
U can't order the same thing twice ( only edit it within the editor ).
The "orders.txt" has to open on a TextBox1 at Form2 ( the text editor ).
And the user can only change the order amount in the edit program.
Example:
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
ListBox1.Items.Add("7226218; Hemlock; 22.55; 0")

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.

Recently I've created a window database program(Tools Inventory); everything works fine except for the following two :
1. It doesn't accept modifications to the existing datas in the column & rows. (Error : Updates require a ValidCommand......)
2. Remove button does not delete the data in the database. It only works in the runtime.

On my add button i still have to add codes that disables my navigation buttons and and my search button... and add codes that will enable them in save button... im still new thats why my codes are just simple if, else if, else conditions that just manipulates enable, visible, text, properties..also if i search my data will be search but my textboxes only shows the searched data.. i still have to add button that will only be visible if the program finds a data... and this button function is to remove the filter..rather than disabling some functions i want a messagebox to prompt the user that this functions arent functionable...
Look at my codes... i find it lame... its kinda irritating always just using True and false..

Is there a way one can edit sound, say for example you have an mp3 sound it is 12sec long, but you want to fit it into 10sec. is there a way one can write a code that automatically adjust the sound so that it only play faster and save it as mp3 again? I am not talking about existing programs to do it. rather a standalone app?

So I have a list of names in a .txt file. Where is a place I can type in all the names I want and press save and get a link so they can see the list. Then I can remove a name and press save and the name will be gone. And or add a name. So basically I need a website where I can type something and keep it uptodate. I've tried ripway but after you edit the list and save it it doesn't change.
