[align=center][size=medium]Visual Basic File Pumper[/size][/align] Components Needed 2 Buttons 2 Radio Buttons 1 Text Box 1 Numeric UpDown Change the text of the buttons "File" and "Pump" And The Radio Buttons To Radio button2="Megabyte" Radio button1="Kilobyte" With the numeric updown there will be no text in it. That will be where you select big you want the file to become (file size) I set mine up to look like this...(pic in spoiler) Spoiler Double click button with the text "File" and add... Dim ofd As New OpenFileDialog ofd.Filter = "Exe Files|*.exe" ofd.ShowDialog() TextBox1.Text = ofd.FileName Code (markup): Next double click the button with the text "Pump" and add.. Dim sfd As New SaveFileDialog sfd.Filter = "Exe Files|*.exe" sfd.ShowDialog() Dim filesize As Double = Val(NumericUpDown1.Value) IO.File.Copy(TextBox1.Text, sfd.FileName) If RadioButton1.Checked Then filesize = filesize * 1024 End If If RadioButton2.Checked Then filesize = filesize * 1048576 End If Dim filetopump = IO.File.OpenWrite(sfd.FileName) Dim size = filetopump.Seek(0, IO.SeekOrigin.[End]) While size < filesize filetopump.WriteByte(0) size += 1 End While filetopump.Close() MsgBox("Successfully Pumped!") Code (markup): and thats pretty much it, ya real easy if you have any questions just post or pm
