im programming this group of hexadecimals this group of hexadecimals are connected to a serial port(drag out from vs 2008 tool bar) so dat the serial port can trigger on or off
however i only need to change a certain portion of the hexadecimal...
ive got some difficulties converting hexadecimal.. for example...i got this group of hexadecimal which is 31 33..when its converted to CHR its 1 and 3 respectively... to make it clearer its 31(hex) = 1(chr) and 33(hex) = 3(chr) but i want to make it 13 instead...because the program i wrote is reading and writing out the value 1 then 3 instead of 13 together..how do i do it???
View 4 RepliesSo I need to write out an object to a text file as well as read in objects from text files.How do I accomplish this? This is the code i've used to read and write just simple lines of text. Is there a small modification to this or just a different function i use to read in an entire object?

I have just recently been using VB 2010 after using VB5. I have noticed a lot of changes. The problem I have is that I wish to open and save text files to and from arrays in the background. I've attached what I would do in VB5. I have searched around, but all the examples I find use a Textbox instead of an array. Can anyone show me how I can do this with VB 2010?
View 1 RepliesI am creating a text file using a save file dialog and copying the path to the text box which file is used to write from vb.net. when i try to write i get an error "The process cannot access the file '....fileName.txt' because it is being used by other program".
The code is below
Public Sub writeInTextFile()
Try
Dim oWrite As New StreamWriter(TxtOutputPath.Text)

I am attempting to gather a group of file names from a directory. I am able to do this. I tested the code by having the list populate into a listbox and all desired items were added to the list.
Here is my code:
Dim di As New IO.DirectoryInfo(strPath)
Dim dir1 As IO.FileInfo() = di.GetFiles("*.txt")
Dim dFiles As IO.FileInfo
ListBox.Items.Add(dFiles)
However, a listbox is not my desired output. I am attempting to write these file names to a text file for purposes of then parsing the information to a datatable to compare with another datatable. How to get my filenames written to a textfile.
I am working on a program using VB.Net 2010 which will enable me to setup groups of files & folders for back up with syncing capabilities etc. I have a concept program which is based on some sample code I found out in one of the VB.Net forums. I have modified it from a command line based program to a form based program. At the moment I consider this code to be a "concept" program which once I have the various copy/sync routines developed and debugged will be integrated in to another program I wrote for
creating "Back Up" groups to automate the process. There are some 3rd party programs that do similar things that I want to do such as Microsofts Sync Toy, but none of them offer the grouping and exclusions options that I am going to program in to this backup/sync program.
So here is my problem, I have the included code taking two folders, a source and a destination, and copying everything from the source to the destination. It will skip over any unchanged files/folders and will delete anything found in the destination folder that is not found in the source folder and it will update all files in the destination folder that have a newer version in the source folder. In other words it will mirror image the source to the destination but will be smart enough not to copy unchanged items from the source to the destination thereby saving a lot of time. The sync part of the program is working fine, the displaying of the progress and results is not.

I have a structure in memory which is working fine - now I need to write this entire structure to a file.The below code almost compiles, the problem is that "mstaRecordInfo" cannot be changed to a string, probably because of the Date field.

for a school project I have to write data from a listbox to a new file that a user can create. I can create and save a file no problem, but for some reason I can't write anything. I followed the textbook provided but when the file saves, I open it up and it is blank. I'm using fileWriter.WriteLine and I'm just test something basic to write to a file first and I can't do it:
Code:
Private Sub storeFileButton_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles storeFileButton.Click
'creates a new file
Dim result As DialogResult ' stores the file
Dim fileName As String ' name the file to save the data

Well I'm in the middle of making a program to edit .ini files. Although I have hit a snag. I can save my settings (relies off checkboxes) with ease, however if I change something and/or hit the save button again even after the code has finished, both my entire .ini files are cleared (filePath and filePathPrefs) and all text is gone. Here's my

Im having trouble creating and then writing to a file. First, I check to see if the file exists, if it does not, then I create the file, close it, and then open again for appending text.
