I'm making somewhat of a File Shredder, wherein, it overwrites your file with a random combonation of 1's and 0's, and i was wondering, is there a way to, once you've overwritten the file, rename it to a 'random' name?How it works: (Not very effective, I know)It overwrites the file w/ 1's and 0's.Basically, theres a textbox, where a 'random' combonation of 1's and 0's(Here after known as 'data') come sup everytime.So, it overwrites wht is on that file w/ the 'data' and saves it, using a save file dialog.Is there a way so that when you save it, it saves it as a 'random' name? Like if the file was 'MY INFORMATION' Once overwritten it'd be like l_fnfu4ufhf or something.
View 3 RepliesI inherited some code left behind by a previous programmer and it includes code in a Sub named Form1_Load. Now, I know this was auto-generated at one point, but Form1 no longer exists. At least I don't think so. My question is, why does this Sub even run? Is it because there are copies of the original Form1 in the working directory no longer associated to the solution? I'm going to save the solution and rename the Sub to resemble the new form name to see what happens.

I want to rework and rename an existing application and utilize everything I've already done -- but it looks like it isn't going to be that simple?One post suggested renaming the folder, plus the project and another subfolder but when I opened that folder there were another 7 or 8 files that also needed changing.I DON'T want to do anything that will create a conflict and if I'm going to change to newname from oldname, I don't want to see "oldname" popping up anywhere..Is there a safe way to rename and reuse an exisitng project? Without anything being left out ?

Visual Studio 2010, Visual Basic I am able to import a .csv file into a datagridview on my windows form using the code below:
Private Sub Button1_Click(sender As System.Object, e As System.EventArgs) Handles btnChooseList.Click
Dim fName As String = ""
OpenFileDialog1.InitialDirectory = "c:desktop"
[code]....
My issue is that I can get the .csv data into the datagridview, but I need the user to be able to indicate which column is the "First Name", "Last Name", "Address", etc so that I can add the data to the correct column in the database. The imported lists won't always be in the same column order.The end result needs to be that the data in my datagridview will be altered by the user and then saved to the correct columns in my database.
I use Visual Basic 2008 I use bound Datagridview I use mysql database If i run this code, everything on the screen ( in the datagridview) neatly Updated.But when I look at records in the table "stock" always the first row (0) of the DataGridView not updated in the table "stock"All the other record are updated with where in the datagridview! This always happens!!!How can fix it?
myAdapter2.SelectCommand = myCommand2
MyBuilder2 = New MySql.Data.MySqlClient.MySqlCommandBuilder(myAdapter2)
MyAdapter2.Fill(MyDataset2, "stock")
MyDataTable2 = MyDataset2.Tables("stock")
