To get the snap shot of other machine

To expand on the previous reply - CreateGraphics is used to draw something that is temporary, it gets erased the moment the control redraws itself. After the control loads, it will become visible, and will redraw itself.

Unless you write two applications, you can't do this. The "other machine" has to be running an application that listens for a connection from your other application running on your machine. When that connection is established and a command given (your choice of what you want to use here), then your client application can take the snapshot and send it back to the server.

MSN Messenger Live Contacts Lits

17-Mar-08 9:22

Why are you asking this over and over, on all the forums, but when someone gives you an intelligent answer, you just repeat the question ? It's obviously beyond you, stop spamming the site, and read the replies you have been given.

Dynamically load the exe and run

17-Mar-08 7:42

Google for "ownerdraw listview[^]". and you can build a custom control to do this.

I want to load .exe file which is created using VB.Net or C#.Net Application.

After installing when my computer starts that exe run.

I am creating set up of the project.

I *think* you're saying you want to add a path to your exe in the startup folder of the run menu, so it starts when the PC starts.

hai SJS4U..

I understood your problem..

for every restart of your PC your application has to be lunch automatically at the start-up.

For this one you have to place your exe stortcut in startup folder..
But We(.net Developers) have a option when we are creating Setup of our application.

Follow the Steps:

--> Goto File System window in setup application.
--> Right Click on the Root (File System on target Machine). U will get the menu ADD SPECIAL FLODER , then select USER'S START MENU.
--> U Will get a Folder in sub-root.
--> Place your EXE short cut in that folder..
--> Built Setup. ( Do Remaining things normally.)
--> Now Install Your Application and restart Your PC. Cool | :cool:

Thanks

Thanks for the Valuable information.

I trid but it is not running when I restarts the PC.

I Copied shortcut of my exe into the user's start Menu folder.

and Buld it but it is not working.

Christian Graus17-Mar-08 0:40

It *has* to work. IF the shortcut is there, windows will run it when it starts. No question. The problem lies elsewhere.

Hash Code for an image

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()

Christian Graus16-Mar-08 23:50

16-Mar-08 23:50

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.

Dave Kreskowiak17-Mar-08 7:37

17-Mar-08 7:37

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. Big Grin | :-D

True??

How to turn off power of other machine

17-Mar-08 7:34

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.

Hi,

I want to turn on/off power of other machine using theASP.Net.

How can it be possiblr?

Christian Graus16-Mar-08 22:54

16-Mar-08 22:54

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.

Dave Kreskowiak17-Mar-08 7:31

17-Mar-08 7:31

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.
