Instead of going through each one and typing that is there a simpler way?
We can watch the file action by FileSystemWatcher but it give us to only create,rename,delete or replace action report, can we get file access action ? for example when user double click any file? or when run any application?

Does the File Watcher class in VB.NET only watch one folder? Or can I have it notify me of any change in the whole drive?

View 1 RepliesI have a label that reads a random line from a text file and that string becomes the text for the label.
Now the problem; the label will only work if it is clicked because the event handler is click.What I need is this to work automatically at startup. In other words, it should change the label's text to the random string of the text file on startup of the application.
Here is my code.[code..]

CD1,11.00,111111

What is the best way to go change the price of the appropriate CD if I'm given the id# and new price?
I'm sure it has something do to with getting the line and splitting it, but I'm not sure how I edit just one line and not mess up the whole file.
How do I change bytes [text stored in those bytes] in a binary file?
I have a little function that read bytes 335-343 [For Keyer] and bytes 344-352 [for verifier] and displays it. These bytes store who the keyerID and VerifierID of a data entry file are. From time to time the Verifier Resumes the file [to insert new records], and his/her name gets stored in the KeyerID bytes. So if the original keyer had lots of errors, the new verifier now becomes the owner of this file and the errors are attributed to him/her [not fair]. He/She gets penalized when there are lots of errors.
My question to you is, how do I change the content of those bytes and save it to the file, without damaging any part of the file? I want to save 'H345' in those bytes, [H345 is an example of a Keyer/Verifier ID]
note - as of now I am using 010 Editor [binary editor]to manually change those bytes. When I use this editor, I can see the text portions for those bytes.[code]...
I have a line of tetx. I must change the value of X an Y column according to the initial value which is input by user. I have a text box for user to enter row and column and also text box for the user to enter intial value of X and Y
It should work like that. If have 10 lines then user wil input row =2 and column=5. Row always will be 2. Initial value for X=100 Y=100
the first line should be 100 100 whic is initial value.
my output will be like this
X Y
100 100
102 100
104 100
[Code]....

108 100
100 102
102 100
104 100
106 100
108 100
The X value must plust with 2 until X=column meanwhile Y remain unchange . then at 6th column which is second row X=100 Y will be intial value of Y+2=102 the the same process will be repeat for second row.
This is my code so far
Dim lines1() As String = IO.File.ReadAllLines("C:\wirematchesout.txt")
Dim xValue As Decimal = Val(TextBox1.Text)
Dim yValue As Decimal = Val(TextBox2.Text)
Dim altValue As Decimal = 2
Dim lineTracker As Integer = 0
[Code] .....
Now I don't want to depend on the column value which is input by the user. I want to do automatically.Let say If my text file contain 131 lines. Since my row will be 2 which is fixed so it should take 66 lines as first row and 65 lines as second row and do the process that I explain above. If line is 132 then it will be 66 for first row and 66 for second row.

View 1 Repliesi am currently doing a project for my course. My project is creating a system for a mechanical workshop, this includes customer information, car information, expenditure ect. I am not allowed to use access to store the information as this will decrease my overall mark on difficulty hence i am going to use files to store the information. I am using VB 2005. I have tried with binary files, this was good at first as it stored data in a record but then when i tried to create a algorithm to search the data it failed.
1) Should i change my file from binary to text or another type?
2) Anyone have any ideas to search within a binary file? If you do can i get some code please.
Basically I want to have a textbox (TextBox1) that when you enter an area code (ex. 512) that it will return the state (TEXAS) in the label (Label1). One way that I had been trying before was to reference from a text file the array that I am using which happens to be in the format of 512, TEXAS.
Sample -
TextBox1: 512
Label1: Texas
[Code]...
I would like to use this for multiple area codes and have been unsuccessful in getting it to work.

I have written a text editor for an assignment but I am struggling on where to start on this bit. What I Want To Happen:- When the user saves there work I want the name of the file to be shown next to the name of the program at the top left hand side of the form. I am not sure If I just need to create a simple sub routine for adding the name of the file then calling the method in the save as routine.

I know in the older versions of Visual Studio, there was an "Add Watch" option where you can choose to stop execution when the value of the field changed. I am using VS 2010, and I can't figure out how to hit the breakpoint when the value of the field changes.
