I have a code to rewrite an ini file, but characters such as 'ñ' will get changed to '?'. This way my whole ini file will get ****ed up, I have no idea to fix this and this is a serious issue for my application.You can find my whole source file here:
View 4 RepliesI was trying to make a program which displays two chars A and B on the screen. Using the WASD keys, it lets you move the A char around and using the arrow keys it lets you move the B char around.
I wrote the following:
Module Module1
Dim Box_A(1), Box_B(1) As Byte
Dim Allow_Draw As Boolean
[Code].....
When I run the program, if I press any of the WASD or arrow keys the corresponding char doesn't move. To make it move, I have to hold down any of its keys for a bit after which I can move the char just by pressing its keys. But then, I have to do the same for the other char.
So, if I want to move B I have to hold any of the arrow keys for a bit. Then I can easily move B just by pressing any arrow key once. Then to move A I have to hold any of the WASD keys for a bit and then I can move A just by pressing any WASD key once.
Is there any way I make make each of the char move just by pressing its ket once?
I borrowed part of this routine to download files, and it works great; except when I download text files the returns aren't written into the outputted file. I've tried different web request and techniques with no luck in solving the problem.

Trying to read and display the text between two re-ocurring characters with a Serial connected device. The beginning of string starts off with "+8" and ends up with "0+". The string displays correctly between the characters, however I do not wish to see these characters. Here is my code that I used from a serial comm chat. P.S. this displays on two lines, the characters that I'm asking about are on the second line.

As Object, ByVal e As System.IO.Ports.SerialDataReceivedEventArgs) _

I'm creating a simple forms application where users can enter their details and save the information to a .ini file because I needed this for a simple game profile. I've tried to make it write "Name =" + txtname.Text but it won't work anymore. And as well as that, I don't think It will load the text back from the ini file.
Here's the code I used;
Public Class Form1
Dim hFile As Long
Dim sFilename As String
Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
[Code] .....

I need to read a value (and possibly adjust the value) in HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall key on both 32 and 64 bit systems.I've tried accessing 'stuff' by compiling my widget as both a 32 and 64 bit app, but nothing is working. Then I came across some information indicating that this could be done from a 32 bit applicaiton using KEY_WOW64_64KEY [URL] somehow, but I can't figure it out.
1) Check the existing value of HKLMSoftwareMicrosoftWindowsCurrentVersionUninstall{ProductGUID}DisplayVersion handling both architectures.
2) If the value <> "" And <> Our Current Version Then
3) Write the Current Version to the value mentioned in step 1.
I wouldn't think this is that difficult as I've worked with registry before, but the 64 bit stuff is throwing me for a loop.It would be nice if I could compile my app to target AnyCPU then detect where its running on 32 or 64 bit. The app could then look and update in the appropriate location.I currently am set to use .NET 2.0, but could go to 4.0 if there is something in there that makes the above tasks easier.

I have created a small game for my son and after each game it tells him his score.all I want is to write the highscore to a file and have it open each time he begins a game..so he can see what his last score was. I dabbled with all this Io.file stuff and I just can not seem to get it to write to the file..also how do I work with app path in this case? I mean when the game is done and installed the current path of the save text would change.
View 6 RepliesIm trying to get my program to fill out textboxes with information it reads from a database, and then save the changes to the database. Does anybody know any good tutorials of this which i could look into?
View 6 Repliesseeing as '.dat' files contain only what you want them to and there is no preset encryption for them etc could I write data to one by using this simple process:
1) Change file extension to '.txt'
2) Decrypt
3) Write
4) Encrypt
5) Change file extension to '.dat'
and pretty much the same for reading it. or am I thinking to simply?
I thought of the above way as i know how to write to text files already, but is this the best way to do it? or is there a better way?
EDIT: Nevermind you just write to it like a text file and encrypt/decrypt it. request lock/delete from mod.
I've been trying to find a solution to my problem for quite a while. I need to build a program that reads data off of the screen, recognizes characters and images and then acts based on what characters and images are. For example, I provide it with a picture of a dog, a picture of each possible character, and it would be able to read the screen and tell me where the dog was, where the characters were and in what order, etc. Is there a free library for this out somewhere? I prefer something that can be used in C# or Vb.net

I am trying to create a bunch of records, there will be a limited number of "Codes", about 50. Each "Code" is associated with a name from a textbox, I was trying to have it save each one when you click a button, to a .txt file.So, from the start the record will be blank, the person will go through the form, choose a number from a numerical up and down box, pick a name associated with it (both of these are mandatory and not implied). When they click the button, it will save the contents I talked about into a .txt file, say the number is #2, and the name is "Bob", the next time they try to change that value for #2, it will overwrite "Bob".

View 2 RepliesI'm trying to write a program that will read a text file, and sort of filter out some things into some new files for myself. I have a website that I like to put information such as Artists, and songs for music. My website writes the Artist, and Song I input to one file on a new line in the format of (Artist - Song). The problem is it's gotten massive! I want to start organizing my artists, and songs anyway I come up with but I don't even know where to begin. To narrow it down I want to go into the file grab the artists name before the (-) and then write it to one file. After that I want to write everything after the (-) which is the songs to a different file. What file reading, and writing method should I use? As you might be able to tell I'm quite the noob.

how to read and write a text file in vb.net
View 7 Repliesfew weeks ago i heard my teacher say that it is possible to view any file as a binary array (1s and 0s). if this is possible to do in visual basic please let me know how. Also how would i go about writing an array of binary to a file? For example 01100001 in a .txt file would produce "a"

View 3 RepliesI'd like to know if there's a better way to read/write various user settings to disk. My program loads up a bunch of settings during load but also during execution from a few different forms, encrypted string values, boolean values, different types. The code seems to work okay but I have a feeling it's just not the best way to be doing this. Some of the settings are encrypted strings that have to be decrypted/encrypted so the code to read/write the text file is a bit different on some items. The data read from disk usually goes to a public string, a textbox, or a up/down type control. Below is about 1/10th of the settings that get loaded/written at various times. Anyone have a better way that might be more efficient that I should look at?
