In this tutorial i'm going to tell you how to change file extensions.
You have a form containing: 2 buttons, 1 textbox (or combobox)
When you click button one you can say it must open a openfiledialog:
Now double click on the other button and fill in the code above.
That's it!
Dim type As String = ".mp4"
MsgBox(TextBox1.Text + " is changed into a " + type + " file.")
Dim oldFile As String = Mid(TextBox1.Text, 1, Len(TextBox1.Text) - 4)
FileCopy(TextBox1.Text, oldFile + type)
How to use it:You have a form containing: 2 buttons, 1 textbox (or combobox)
When you click button one you can say it must open a openfiledialog:
Dim ofd As New Openfiledialog If ofd.showdialog = dialogresult.OK then TextBox1.Text = ofd.filename End IfIf we click the button, a openfiledialog will appear and we can choose a file name and if we click on 'ok', then the textbox will contain the filename of the openfiledialog.
Now double click on the other button and fill in the code above.
That's it!
