Changes And Updates Are Being Written Directly To The Text Files?
Nov 2, 2009
I am having a hard time with my project. A description of it is here (Question #2) I don't know where to begin with classes. I have a functioning program, but it isn't working as designed. Changes and updates are being written directly to the text files, so the listbox doesn't display current information unless it is refreshed in some way. The instructions say that this program should commit files once a "Save accounts to File" button is clicked. Obviously, my program doesn't make use of the button. I was going through another project where changes were written to a list box, and committed to the files upon exit. However the text files were in LSV format, and the program used an array of structures instead of classes.

i would like to know if it's possible to save text files into my app. that way there is no folder to contain those files. i'm thinking that i might need a separate form to hold such information, like creating a new textbox for each saved file and it's content, then loading the files from that form's textboxes.

We use a program, called CFPS (a flight planning program) and it creates different flights. I can export this file to a CRD-type. When I open it in Wordpad or something, it looks very familiar to a XML-file ("<item></item>...")...but I don't find a way to read it. What is the best way to handle this problem? It would be time saving if I can import these files directly in my program.

I am wondering if there is a simple way to make the text to speech occur after the updating of label.text
If I have the following:label.Text = "words words" voice.Speak(label.Text)
I would like the label on the form to display "words words" before it speaks. I'm a beginner with vb, and the only thing I could come up with was to use a timer. Just wondering if there's a simpler/more sophisticated solution.

I would like to develop a program (in VB2008) that can send files directly from one computer to another through the internet.
I figure there would be one program on the sending end and a separate on the receiving end. A server and client perhaps?
Anyway, I need to know how to send a file on the host machine in a simple method that is least likely to be blocked by anti-viruses and such. The fewer issues that result in a failed transfer, the better.
Also, note that my goal is to molulize this code (later) so it can be reused for multiple applications such as file sharing, gaming, etc.

I'm trying to make my app check for updates by reading a text file and comparing it to a 'currentversion' setting in my application (or if checking the executable file version is easy, that would be good).
Here are the basic steps: -Read text file hosted on [URL]..-Check if the version number (eg '1.1') is higher than the number in the 'currentversion' setting or the executable file version (whichever is easier).
-If the text file version number is the same, change form background colour to green, if it is higher, change the background colour to red.

Let me preface this by saying that I'm very much a novice coder. I'm currently working on a small project to practice with Visual Basic and have experienced some issues during my save and load process using text files. I think I can solve the issue by changing the way my text file is initially saved. I want to see if I can sort the items and change the order in which they are written to the text file based of the value in one of the lines.[code]....

I tried to write a text written in my textbox to file.(a .txt). I scanned it to see if it contained any illegal characters, the program said that it did not. However, when I went to save it it said that the program performed an illegal operation.
System.Runtime.InteropServices.COMException was unhandled Message: Exception from HRESULT: 0x800A0005 (CTL_E_ILLEGALFUNCTIONCALL).
It created the text file but did not write the content of the textbox to the file.I can save the text in Microsoft word without a problem. Is there something wrong with the encoding for the textbox and how do I set the encoding for the characters so I can write it to a text file.
