View 7 RepliesI am making just a simple program that will create backup dummies of all the files in a specified folder. All I have is 2 text boxes, A and B, and a button to do the magic. What I want is for the user to input into Text Box A the location of all the files, and in Text Box B place in the destination folder, then when the button is pressed it will get the name of each file using a loop and recreate a new file with the same name and extension in the destination folder

View 1 RepliesI was able to get some code working to create a dummy file to fill the remaining space of a flash drive. However, I have added a progress bar and can't figure out why it's not working. I declare a variable for the current value, min, & max properities of the progressbar and then increment it by 1 during each step of my FOR loop. However, I never see anything on the progress bar.

View 4 RepliesI created a custom control and add it to a form programatically.
The user can add and move them all over the form.
The problem is when I want to clear the form of my user control I don't know how.

Say I create ctlCorkNotes(1) and now I want to delete it.
How do I do this so it is gone and would have to recreate it to show up again?

View 1 RepliesI am making just a simple program that will create backup dummies of all the files in a specified folder. All I have is 2 text boxes, A and B, and a button to do the magic. What I want is for the user to input into Text Box A the location of all the files, and in Text Box B place in the destination folder, then when the button is pressed it will get the name of each file using a loop and recreate a new file with the same name and extension in the destination folder.For example:
C:FolderX has 10 files in it, each with the same extension (.wav), each file is ranging from 10mb to 100mb (this size is irrelevant)
C:FolderY is empty
What I want to do is create each file from X into Y, however the files are all 0 bytes (no data inside them). I've managed to get a simple script that will do what I need but only if I specify the file name:
Code:
Private Sub Button1_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles Button1.Click
Dim Filename As String = My.Computer.FileSystem.GetName(TextBox1.Text + "test.wav")
Dim SaveP As New System.IO.StreamWriter(TextBox2.Text + Filename)
SaveP.Close()
MsgBox("Files Created")
But what I need is someone to show me how to create a loop that will do this for each file in the folder, without me specifying each filename.
How can be find out which file is going to delete when, user provides command like DELETE or SHIFT + DELETE or by programmatically gives DELETE command. Well I know about FileSystemWatcher Class, but this class doesn't provide information before delete...
