Hi friends, i need to know how to get the hash code for an image in vb.net. When i try by using this code i get different hash code for the same image. Please help me any one on this
Dim img As Bitmap
img = pbxPreview.Image
Label2.Text = pbxPreview.Image.GetHashCode().ToString()

Well, if you get different codes for the same image, that probably means the framework doesn't really support it ( which is odd ). What do you mean by 'the same image', where does it come from ?
If this is true, there's not going to be another way, you'll have to write your own.

GetHashCode returns the hash of the object instance, not it's data. I figured he'd probably have to dig into some of your C# code to get the image bytes and run that through one of the encryption hashers to get what he wants.  True??

yeah, that's what I was expecting if he needed to write his own.

This code doesn't generate a hash of the image contents, rather its for the Image object (instance of a class), not it's data.
To generate a hash of the image data, you'll have to treat it as an array of bytes and run that through an encryption hashing algorithm of your choice.

Wow.
Start here[^], but also buy a VERY basic ASP.NET book and read it, so you start to have some basic idea of what it is, and what it does. Once you understand what is meant by the term ASP.NET, you will understand why you can't possibly use it to turn any computer off.

Don't you want to send a ctrl-alt-delete sequence? Seems like that should be possible. Through ASP, I have no idea though.

This is not possible using ASP.NET.
Client hardware and the Windows system is off-limits to your ASP.NET code, as well as any code running client-side in a browser.

That's not going to turn off another computer...

|

Maybe it is possible.
You can use vb6.0 or any tools to use win32 api to shutdown pc.
If you want to use ASP.Net you must crate ActiveX that have ability to shutdown pc and you embeded it in ASP.Net page.
And tell user on other machine to load your page.

Why VB6? It has been pretty much dead since March of 2005. You might want to use VB.NET instead...

Well, your flash drive shows up as a hard drive on the system, so you could watch for removable drives being added or disappearing

Keep a list of removable drives on the system, set a timer and see if it changes. There may be an event you can hook into instead, but if not, that's the other way to do it.

Hi..,
Use this code for detect your flash drive when insrt/remove.
This is event based code. using namespace system.management.
declaretions:
Private WithEvents m_MediaConnectWatcher As ManagementEventWatcher
Query:
Dim query2 As String = "SELECT * FROM __InstanceOperationEvent WITHIN 10 WHERE TargetInstance ISA ""Win32_DiskDrive"""
then start the managementeventwatcher thread.
m_MediaConnectWatcher = New ManagementEventWatcher(query2)
m_MediaConnectWatcher.Start()
you will get a event when you insert/remove.
Thanks

hi.
I work on a telephony windows application that works as an answering machine and uses TAPI over a voice modem.
I used some *.wav files in the application that they give command options to the users when they call to the application.this application is going to sell to different customers so I want to have an option to chenge the *.wav files on my application.but my problem is that I want to embed *.wav files in a resource file such as "WavRes.resX" .
thanks.

The short answer is that you can't change out the resources at runtime. The long answer is that you can, but with GREAT difficulty. Once the .DLL is loaded, it's locked read-only. Meaning you can't change it until the process the loaded it stops.
For your description of what you need it for, I would suggest either copying an already made .DLL to the filename you need it to be, or your code should be able to load the correct .DLL library without modifying any files.
