[VB.net-APP] - Delete Cache

[zubair1]

Hello,

Could some one help me on a problem..

I am trying to delete all the cache Internet Explorer has..

but theres a file in the cache folder called Index.dat which it doesn't let me delete - i have browsed around for a while but couldn't find any solution.

I got an idea from a blog writter - saying that i could do it by marking the file for deletion ... :s but i dont know how do i do that :(

So it gets deleted the next time the computer is rebooted

please would really appreciate any assistance :)

Regards

Try to find out which process uses the index.dat and then kill that process...Then, try again...

And you really have to be more patient with bumping posts...You can't expect a reaction in just 7 hours of time...The time you posted was 2 AM GMT :p

Thanks MrMancunian :D

yeah... but i just couldn't wait :(

i've been looking for a solution for this for over a week now but none yet :(

i joined Bytes hoping i could resolve my problems here since it looks like an active community with skilled experts and all :) i usually dont join Forums/communities =P :D

Ever since i posted the question here i've been on a lookout for a solution virtually everywhere on the internet :( i found one which was in C++ :( and VB.2003 :( so it wasn't for me i did email the author if he code port it out for me in VB.net alittle or atleast tell me how to do it in VB.net - but that was just 10 mins ago so i haven't received any response yet :)

Though his post was mention stuff you said like about the processes -

There are TWO process which uses the Index.dat files first the explorer.exe and second iexplore.exe.

I was thinking - if i close both of these processes wouldn't the user be able to tell that i'm doing something like this or might scare him :o (just wondering)

Does anybody has a better solution?
I have heard of another one myself :D Its to mark index.dat for deletion - so that the next time the windows reboot it will be deleted but how do i go about doing that its completely out my mind :( i'm just a newbie here :( been only a week since i got started with VB.net :( (maybe less).

could some one provide some code to help me get started here :)
i dont have money :( but i can say Thank You =D

any help plz :(

I found this that may be helpful:

class Program
{
	[DllImport("kernel32.dll", CharSet = CharSet.Unicode)]
	public static extern bool MoveFileEx(string
		lpExistingFileName, string lpNewFileName, int dwFlags);

	public const int MOVEFILE_DELAY_UNTIL_REBOOT = 0x4;

	public static void DeleteOnReboot(string filename)
	{
		if (!MoveFileEx(filename, null, MOVEFILE_DELAY_UNTIL_REBOOT))
			System.Windows.Forms.MessageBox.Show("Failed");
	}

	static void Main(string[] args)
	{
		DeleteOnReboot(@"C:\test.txt");
	}
}

You can use it to mark a file for deletion on reboot. That way it'll be deleted by the Windows subsystems as it comes back up. Alas, I couldn't find anything in the .NET Framework that does the same thing...

WOW

Thanks alot ben :)

Looks pretty awesome :)

Is that for Visual C++ :o :( i do have it installed but havent used it yet :(

i was wondering if i make this code into c++ and make a small application
is there any possible way i could call that c++ app to mark these files for deletion

or could you provide any better way to call this function from my VB.net program sir :(

I'm lost on what to do with this code :(

Please advise :(

Thank you

You could just dump it into a C# to VB converter such as the one found at labs.developerf usion.co.uk... I took the liberty of doing it for you:

Class Program 
    <DllImport("kernel32.dll", CharSet := CharSet.Unicode)> _ 
    Public Shared Function MoveFileEx(ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal dwFlags As Integer) As Boolean 
    End Function 
    
    Public Const MOVEFILE_DELAY_UNTIL_REBOOT As Integer = 4 
    
    Public Shared Sub DeleteOnReboot(ByVal filename As String) 
        If Not MoveFileEx(filename, Nothing, MOVEFILE_DELAY_UNTIL_REBOOT) Then 
            System.Windows.Forms.MessageBox.Show("Failed") 
        End If 
    End Sub 
    
    Private Shared Sub Main(ByVal args As String()) 
        DeleteOnReboot("C:\test.txt") 
    End Sub 
End Class

Hello

Thank you so much sir :)

really appreicate your help :)

i tried copy/pasting the code into my vb.net

but its giving an error - Type 'DllImport' not defined.

Below is the code i am pasting

    <DllImport("kernel32.dll", CharSet := CharSet.Unicode)> _ 
    Public Shared Function MoveFileEx(ByVal lpExistingFileName As String, ByVal lpNewFileName As String, ByVal dwFlags As Integer) As Boolean 
    End Function 
    
    Public Const MOVEFILE_DELAY_UNTIL_REBOOT As Integer = 4 
    
    Public Shared Sub DeleteOnReboot(ByVal filename As String) 
        If Not MoveFileEx(filename, Nothing, MOVEFILE_DELAY_UNTIL_REBOOT) Then 
            System.Windows.Forms.MessageBox.Show("Failed") 
        End If 
    End Sub 
    
    Private Shared Sub Main(ByVal args As String()) 
        DeleteOnReboot("C:\test.txt") 
End Class

Hi,

just a follow-up to my last post

I think i found the solution by doing a small search :)

Imports System.Runtime.InteropServices

I had to add this namespace into the code and it wasn't showing errors after that.

:)

[zubair1]

DeleteOnReboot("C:\MyFile.txt")

[zubair1]

DeleteOnReboot("C:\MyFile.txt")

yup, got that - Thanks alot Mr.Expert =D

The code is working smoothly - the code you posted i found earlier and had it saved in a separate text-file but it was in C language :( but you also showed how to convert it which i never new was possible :D

Thank you so much for the awesome help sir :)
