How To Confirm About File Deletion
Jul 20, 2010
I have this in my form closing event:
For Each FileFound As String In Directory.GetFiles(App_Path() & "tmp", "*.txt")
File.Delete(FileFound)
Application.DoEvents()
Next
For Each FileFound As String In Directory.GetFiles(App_Path() & "tmp", "*.txt")
File.Delete(FileFound)
Next
I used to run through an ultragrid with a for each loop and that took forever, I stumbled accross this way and it's much faster but I noticed today I still have some straggling .txt files after the form closes at times. Is there a way to actually verify all the files have been deleted before closing the form?
I ran the same for each loop twice to work it out but not sure if that works or worsens it. Also, I'm not entirely sure what that application.doevents does as I initially thought it would finish all above lines before continuing but that does not seem the case. Anyway, these .txt files files are about 500KB and up to 1000 of them at any one time so it's not instant but it's still pretty fast, faster then looping through a grid.

I want to make a very simple program that remove duplicate domain name from a txt file. First, it must have a Open file Button so that it can load list of url to Listbox.
So, the URLs will be loaded into listbox. Then It has 2 more button Start and Save button Lastly one counter to calculate how many URL in that listbox
So example.. let say I have a txt file which contains URLs
[URL]
I open this txt file and loaded it into listbox (can scroll)
Then when I press start button, it will delete the URL that has same domain name. so the output will look like this
[URL]
Then I can save the URL from listbox to my disc drive as text file

Is there a way to detect if a file is being deleted,
1) Using the Del key
2) Using the Shift+Del keys
3) Using the above keys from a remote computer through a shared folder
And instead of deleting move it to another folder in the same computer. Basically when a user tries to delete a file or folder it should move it to a specified folder instead of deleting it.

This is what I have for code:
Private Sub restoreDatabase(ByVal dbName As String)
Dim newDbName As String
newDbName = dbName.Substring(dbName.LastIndexOf("_") + 1)
My.Forms.portfolioGenerator.Close()
[Code] .....
It seems like it should be pretty simple, I take in a file name as a parameter, create a new name for it, delete it, then try to copy it back from an older version of the same file, and update the connection string. However, it continually tells me that "The file 'filenamehere' already exists." If I set overwrite to true then it goes through just fine, except it doesn't actually copy the file. Obviously I also check the folder, and the file does in fact Not exist...I've also checked all the file paths and what-not, they are all accurate.

The code i have so far inputs the users username and pas that they inputted into 2 textboxes. Next the user hits login and it submits the info. Here is where i have a problem. Some users are already logged in when they get to the site, this is a problem because i need to make sure they are logging in correctly. Here comes another problem, lets say they log in correctly, how can i know that the login was successful?
Simplified:
1) How can i find out if the user is already logged in so i can log them out.
2) If they are not logged in, and they log in successfully. how can i confirm that?
If there is any other way to login without web browsers?
'Code to enter the user and pass into the webpage
WebBrowser1.document.GetElementById("Username").InnerText = TextBox1.Text
WebBrowser1.document.GetElementById("Password").InnerText = TextBox2.Text
'Code to click login on the webpage
WebBrowser1.document.GetElementById("submit").InvokeMember("click")

Well, I have a form called customers. Login form and mainform.
So my clients want to have an option that explains this: If a user enters information in the customer form, then that information has to be confirmed by admins panel.
Get me well. When application program loads with a limited user, I set some buttons hidden so that only admin can see it when they log in. so in that case, users are not capable of inserting anything in the customer form.
But this time they want users to insert information then the information goes to administrators to confirm the information...if admins accepts the information, then information is then goes to customers table in database. If they don't confirm it, then that information will be ignored.
am using vb.net 2008 with sql server database.

I have a form where a user can delete a record, and I want a pop up message where the user has to click okay to confirm the delete.
Delete button:
<asp:Button ID="btnDelete" runat="server" Text="Delete" UseSubmitBehavior="false" OnClick="btnDelete_Click" OnClientClick="confirmation();" />
Confirmation function:
function confirmation() {
var answer = confirm("Are you sure you want to delete? This action cannot be undone.")
}
So right now, clicking the delete button executes the btnDelete_Click Sub in the code behind regardless of whether you click okay or cancel in the pop up box. I know I can add if (answer) { -- some code here -- } in my javascript function, but is it possible to use javascript to execute code from the codebehind? Or is there another way to do this?

I'm lending a copy of my .exe on a memory stick and because I dont completely trust them, , I would like to build in a function that as soon as my app has finished doing what its doing And the big red X is hit it will delete itself, but my problem is that i cant put the deletetion in the form closing because the prog is still running, so what should I do? Is there a way that I can get the app to close as soon as the dedicated task is complete, It will remove itself from the memory stick but if the X is hit before the process is complete the then the prog will remain.
