I am trying to create a form where a specific user is deleted from a file. The file has all its contents encrypted using the MD-5 string to hash method. I know that i have to create a new file copy everything over except for the user to be deleted, kill the original file and rename the new one.
Private Sub OK_Click(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles OK.Click
filename = "users.dat"

how i can able to determine if the user intended to delete a file. What im going to do is this application will be placed in a certain folder together with some files. And this program will determine if the user inteded to delete a file within the folder.
View 2 Replieswhat is probably a very stupid and basic question, I'm new to Visual Basic I currently coding a program which deletes specific files that are part of a game. It finds and deletes all the files in the "program files" directorys but there are also certain files in My Documents that must be deleted.
The problem is the filepath to My Documents includes a username which is unique to different users, meaning on any other pc the program will not work.
The path on my computer is: C:UsersShaneDocumentsElectronic Arts
How can I get the program to find this folder on other computers? I'm totally lost.
I'm creating a PDF file on the fly using ITextSharp and ASP.NET 1.1. My process is as follows -
Create file on server Redirect browser to newly created PDF file so it is displayed to user
What I'd like to do is delete the PDF from the server as soon it is displayed in the users browser. The PDF file is large so it is not an option to hold it in memory, an initial write to the server is required. I'm currently using a solution that periodically polls for files then deletes them, but I'd prefer a solution that deletes the file immediately after it has been downloaded to the client machine. Is there a way to do this?
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...

View 5 RepliesI have a button which loads a table from an MSACCESS file into a listview.
[Code]
When the button is clicked, it runs this function, populating the table into the listview. Now, I would like to add the function where a user can delete rows by right-clicking a row in the listview and selecting delete. I have added a context-menu, and I can delete listview items, however I don't know how to delete the row in the MSACCESS database. Any ideas?

View 4 RepliesI have a login screen (frmLoginScreen) which links to a main menu (frmMainMenu) then to another form (frmUserDetails). Their are two possible usernames. The first one the user logs in as Admin and the password is 4321, then the second one is Guest and no password. This is the code I have so far:

G.btnDelete.Enabled = False

On my website I have user records. For the user records page I have three options you can do with each user record. Delete, Update and Email are my checkboxs's that I am trying to use.
<Input Type=CheckBox Name=Delete OnClick="False" Value=<=rs("num")%>><br>
<Input Type=CheckBox Name=Update OnClick="False" Value=<%=rs("num")%>><br>
<Input Type=CheckBox Name=Email OnClick="False" Value=<%=rs("num")%>>
What I want to be able to do with these check box's is when one of these slections are made, I want to be able to pass the value of the selected checkbox by pressing a button over to another page where I have a IF statement. Then value of the selected checkbox runs though the IF statement and matchs with the option in the IF statement.

So I guess what I am looking for is how do I get the value of the checkbox to pass over to another page and run through my IF to match with an option in my IF statement.
I have a datagrid control with a list of names that it retrieves from a MySql database. I can search through them until i have one result. I want to be able to Display a groupbox control when the number of results is equal to 1. Also, in the groupbox i have a button that when clicked will delete this user from the server and their information from the mysql table called "employee". when the user is deleted i'll display a confirmation message in a messagebox, and reload the table with the updated list. so far the only two problems i have are showing the groupbox when the results are equal to 1 and deleting the user from the sql server based on the name of the search result
