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.

Does anybody know if it is possible to download email messages and send something to the email server to delete an email from the server using ASP.NET?
I have developed a program to download email information from my email server, but I can't figure out how to send something to the server to delete an email. I developed what I have using the resources at this location[url]...
I am sick and tired of all the junk mail I am getting and want to write my own program to delete emails from my email server based on criteria I create.
I have VB 3.0, VS 6.0, VS.NET 2003, VS.NET 2005, VS.NET 2008 and VS.NET 2010 Express. I have developed web sites and standalone programs using VB and ASP.NET. My experience and knowledge is not extensive, but i do have enough knowledge to create a VB program.

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

Am using grids in VB.net to display database records stored in Microsoft Access, the tables allow editing and deleting using the grid fields. Is there a way I can monitor whenever a user deletes or edits a record? I want to be able to view details of every update or deletion to certain records, such as the date and users who did it.

I am using this code for row deleting in gridview. It should be like this "while it deleted a row, take row number 5 with serial no 5, serial field of row number 6 should become 5. means decrementing the serial number after one row deleted." but it is not happening while I delete row no 5 with serial 5, the row number 6 remains the same.

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.

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.

<edit on 10th March 2010.>
Changed thread type to QUESTION. I was then able to mark AS ANSWER the relevent post which now also immediately follows this post and so it is easier to find as suggested by forum user j2associates .
<edit> It is also my 3rd post in this thread, the 8th one up, of my posts, from the bottom ( for now ), as the forum format has changed yet again.I will leave the rest of this post( as is ) purely for historical reasons. I have been on these forums long enough to see 3 forum changes. <edit> 19th May, 2010> Link added to a video on the next line of text.

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.

I was toying with a T4 template's FileManager object, when I seemed to create a ".." folder in my solution. I was puzzled, as this shouldn't really be a valid user-creatable folder,and obviously, no ".." folder was created in the file system. So, I deleted it from within the VS Solution Explorer.I watched for four minutes as the entire contents of my solution's parent directory got deleted.
