I'm using Visual Basics 2010. I'm looking to develop a program that edits certain bytes at a specific offset in Hex. The only problem is, I can't figure out how to edit a file in Hex, through Visual Basics programming.

I'm new here and I'm trying to make a little program with Visual Basic (2010 Express Edition).The purpose of this program is:
1) Load the text file lines and split them into a constant and a value
2) Edit the text file lines values
The content of the text file is like this:
[Code]...
This basically split every lines in two parts: the constant ("Name", "Surname", "Age", "Hair") and the values ("Mario", "Rossi", "50", "Black").Now about the second point, I've added a Button1 which should take the Textbox1/2.Text and the Combobox1 selected item and replace the values(aka separator(1)) in the text file. The problem is I don't have any idea at the moment how to do it. What method should I use?
I have some files that contain strings and an image.I have an offset 0x068 (&H68) this is constant between all the files theoffset contains the offset of the info in the file example would be 0xE9400question being how to seek to 0x068 then seek to the new offset of say 0xE9400?then starting from 0xE9400 get Int from offset 0 size 2 bytesimage from offset 32 size 512 bytesThe icon is a 32x32 picture formed out of 4x4 16 color tiles and a single 16 color palette. Pallet offset is 544 size 32string offset 832 size 128 chars 256 bytes (unicode)I can read the first part of the header and return the string there
Dim header1(11) As Byte
Dim fileOpen As IO.FileStream = IO.File.Open(TextBox1.Text, IO.FileMode.Open, FileAccess.Read)

Im creating a application called FS Acars for a game called Microsoft Flight Simulator. In my acars there is a feature where you can Get the fuel load from the plane, And then you can load the fuel back on. To get the fuel from the plane, You have to use the following code;
CODE:
Ok, so once you press a button called 'Get Fuel', The amount of fuel on the plane will be shown in a Label and also be put on a Track bar, Both in a Percentage Value. Now I want the user to be able to modify the track bar, And once they have done that, They can press another button called 'Load Fuel', Which will get the value of the trackbar, And send it back to the plane to load the fuel. Can anyone tell me how I mite do this. I can allow teamview access to show an example.
i'm trying to make a program that searches for a specific file in a specific file, so when the program loads it "writes" in checked list box the names of the drives installed to the computer, but what i want to do is: when the user checks the box, i want it to search for the file in that drive, but i don't know how to do it...
I'm using:
Imports System.IO
Imports System.Collections.ObjectModel
Public Class Form1
[Code].....
how to make it search in the other drives using the checked listbox?
I wonder if it is possible to find a specific row and specific columns in data base file (Access) . You see , I am using a DataGridView control to show only SOME of the columns (fields) of a table from an Access file . For example , lets say that in the DataGridView control I only show the following fields :Field1 , Field2 and Field3 .Now , when the user selects an entry in the DataGridView control , I want to insert the text from Field4 into a text box on the form .
The problem , however , is that I don't know how to get the specific row in the data base file and also I don't know how to get the text in column (field) Field4 of that row .One thing that might be important is that the index of the row in the data base file is not necessarily the same with the index of the current row in the DataGridView control . This is because in the DataGridView control the rows are order by the contents in the ID Field .ol .

View 9 RepliesI would like to know a way (of course I want to know the best way) to edit a csv file, preferably without having to read the original and write the results to a new one.
Example 1: I want to split the contents of a column into two columns 123abc into 123, abc
Example 2: I want to remove letters from the beginning of a column AB123 into 123
Clarification: I do not need help solving my examples; I just need to be pointed in the right direction of reading and editing the same file.Here is a code example of using a temporary file that seems to me is too slow
Dim currentLine as string()
tempFile.AutoFlush = True

View 11 RepliesI am creating a Flash fully-animated website for a customer, that reads its text and images from an outsource (on the same web host).They requested an admin page to edit the text and images.I am thinking of making a asp.net page that reads the text file into a dynamic textbox.The user can edit it then save it, so the Flash player would read the new text.
My question is, do I need to create an FTP connection with the authorization username & password?Since the asp.net web page would be on the same server, can it open the txt file and edit it and overwrite it without the need for FTP connection?
I'm looking to take a small snippet out of a wave file which I can do by reading in the headers, calculating time in to samples and selecting that data back to another file with the headers appropriate for the new smaller chunk.
My question though is does anyone use a nice small free library that does something like this. With the numerous different versions of wave files and headers not matching I'm trying not to re-invent the wheel and if someone has done it already and can handle these discrepencies that would be amazing. If not I'll fire up the kettle and get the coffee on.
the problem is I'm trying to access a file that has no file extension. I think you can see why this is so difficult. The specific file I'm trying to edit is the hosts file (C:\Windows\System32\drivers\etc\hosts).

I have a text file called: list.txt This is a list with all kind of lines like this:
14II_ARM_S_CLO_CLO_CLOVERIDS_PROPITEM_TXT_01194611IK1_ARMORIK2_CLOTHIK3_CLOAK=TRUE==200050000====PARTS_CLOAK=1==11=1===11_NONE Ofcourse every line has different numbers and letters.
The complicated bit is this:
I want to let Button1 check whats in TextBox1.Text and search "list.txt" for it. When it has got a match (there is only ONE of these numbers in list.txt).For example TextBox1.Text = "IDS_PROPITEM_TXT_011946". And I search for that so I find the line above. Now I want 3 other textboxes which show the 21st, 22nd, 23rd column/number after "IDS_PROPITEM_TXT_011946". And they should be editable by changing those 3 textboxes and clicking the apply button.How can I best do this, and please give a little example.
I have two text files, first text file looks as follows
File1
String1 String
String2 String
String5 String
String8 String
These fields match some of the fields in my File2, but here there is an extra column which shows a numeric field for that row.

I've been banging my head for a while now and just can't seem to figure out what the problem is here. I have not really worked with XML much and thought it would be good to do some work with it in order to have a better understanding. I decided to write a little program to allow editing a game file. I found some examples on the net of basic XML functions and tried to use one of them in my program.
The Xml file I am working with is huge so I will show just enough to give an idea of the format.
Code:
<?xml version="1.0"?>
<Proto version ='2'>
<Unit id ='0' name ='InvisibleProjectile'>
<DBID>20</DBID>
[Code]...
I have tried different text in the select nodes portion, such as "proto" "/proto" and the above but in every case I get a count of 0 on the node list and nothing is displayed in my textbox.Each <Unit> is roughy 30-35 lines and the file has over 59k lines of units so clearly the count should be rather high but always 0.
The idea is to comment and uncomment lines in the httpd.conf file to load and unload modules. This is what I have so far, working, but not always, somehow. But in any case, I don't think this is the proper way of doing this. Any suggestions? [Code]

I deleted 3 old pictures from my resource folder. When building compiler alerted me to missing resources. Stupidly i manually edited the file and all my Toolbar icons are gone. Interesting enough the menu strip text all vanished and so did my status strip text. I managed to add back the deleted lines but still the same. If i delete the toolstrip all its buttons remain. Manually deleting each control, rewriting we are talking hours and hours of work.
