I was looking online for a application that can delete a file more secure then. Kill(C: est.txt")Then i had a thought.Maybe i can make my own.Is it possible to make a secure file deleter in vb.net or should i look into C++
View 5 RepliesI want to make a fairly simple program that would prevent file deletion of certain folders andor files that i would input into the program. Say if someone tried to delete the file it would display an error message.
View 3 RepliesI am developing an application that Monitors a specific folder for file changes such as modify deletion, update, etc. The only problem I have is , the application doesn't fire up File events.
Here is the code:
Imports System.IO
Imports System.Diagnostics
Public Class Form1
[CODE].............................
I have this in my form closing event:
For Each FileFound As String In Directory.GetFiles(App_Path() & "tmp", "*.txt")
File.Delete(FileFound)
Application.DoEvents()
Next
For Each FileFound As String In Directory.GetFiles(App_Path() & "tmp", "*.txt")
File.Delete(FileFound)
Next
I used to run through an ultragrid with a for each loop and that took forever, I stumbled accross this way and it's much faster but I noticed today I still have some straggling .txt files after the form closes at times. Is there a way to actually verify all the files have been deleted before closing the form?
I ran the same for each loop twice to work it out but not sure if that works or worsens it. Also, I'm not entirely sure what that application.doevents does as I initially thought it would finish all above lines before continuing but that does not seem the case. Anyway, these .txt files files are about 500KB and up to 1000 of them at any one time so it's not instant but it's still pretty fast, faster then looping through a grid.
I want to make a very simple program that remove duplicate domain name from a txt file. First, it must have a Open file Button so that it can load list of url to Listbox.
So, the URLs will be loaded into listbox. Then It has 2 more button Start and Save button Lastly one counter to calculate how many URL in that listbox
So example.. let say I have a txt file which contains URLs
[URL]
I open this txt file and loaded it into listbox (can scroll)
Then when I press start button, it will delete the URL that has same domain name. so the output will look like this
[URL]
Then I can save the URL from listbox to my disc drive as text file
Is there a way to detect if a file is being deleted,
1) Using the Del key
2) Using the Shift+Del keys
3) Using the above keys from a remote computer through a shared folder
And instead of deleting move it to another folder in the same computer. Basically when a user tries to delete a file or folder it should move it to a specified folder instead of deleting it.
I need to execute the following commands from my application:

This is what I have for code:

It seems like it should be pretty simple, I take in a file name as a parameter, create a new name for it, delete it, then try to copy it back from an older version of the same file, and update the connection string. However, it continually tells me that "The file 'filenamehere' already exists." If I set overwrite to true then it goes through just fine, except it doesn't actually copy the file. Obviously I also check the folder, and the file does in fact Not exist...I've also checked all the file paths and what-not, they are all accurate.

I have a program that can save to a .txt file.The issue is I need it to be done in a tab delimited way.Basically:
TextHere<Tab>TextHere<Tab>TextHere<NextLine>
TextHere<Tab>TextHere<Tab>TextHere<NextLine>
I have this so far, but all it does is put the TextBox1.Text next to TextBox2.Text
Code:
SaveFileDialog1.Filter = "Text files (*.txt)|*.txt|All files (*.*)|*.*"
Dim FileWriter As StreamWriter
Dim results As DialogResult

View 4 RepliesI am using VB 2008 express and SQL Server 2008 express on a test basis and I used to connect VB express to a SQL database (created in SQL Server 2008 Express management studio) file and it work perfectly until my hard drive packed up and I had to get a new one, so I had to reinstall both of these again and copied my old databases from a backup I had. Now when I try to connect to the database file it cannot connect. Network related error or the instance name is incorrect. When I look at the advanced options in the connect dialog it shows my instance as .SQLExpress and my correct instance name is .SQL2008Express. I clicked OK on the connect dialog and manually changed my connection string to the correct instance and that worked but whenever I run the application in debug mode it give me the same error as above.

View 3 RepliesI have a text file that the first part of my program writes data to, but for this second section, I need to read that file and use pieces of that data and average them out. The text file is setup up with 90 lines of data starting with the first 9 lines containing data and the 10th is a blank space. I need to read line 6, 8, and 9. I need to Loop through the file so I am using the Do While Loop. Where I am confused is when using the For...Next Loop to tell the program to read a specific line.

I would prefer you just point me in the right direction because I would very much like to somewhat figure it out in the process.

View 5 RepliesI have been able to use my.resources perfectly, no problems at all. all of a sudden, i try to use resource (i have done EVERYTHING EXACTLY the same as the way i have been using for the last 1 and a half years) and i get an error saying the file does not exist. its there, i only need to type my.resources.s and it already selected the resource i want. it says the file doesn't exist. why? also, the resource is called settings.dat. could that be the problem, don't think it is. i even tried a picture, but it still says the file doesn't exist.
It says: Could not find file 'C:Users[username removed]DocumentsVisual Studio 2008ProjectsdiskSaverdiskSaverinDebugSystem.Byte[]'.
I worked out a way around it (i worked out how to use my.settings in stead), but i haven't worked out why my.resources won't work.
