The best way to do this is to use Visual C++ or .NET's C# and use an image object to hold the binary image data as you address/manipulate it. If you are doing this as a web-based application, then ASP.NET using C# is the way to go, again using an image object. 
There are many helpful developer site for the beginner through expert that can walk you through the use of an image object. There are also many variants of the image object and you'll have to decide which one best suits your needs. Start with the generic one to get your base code loading and addressing the image and go from there.
Here's a good starting point.
Hope this helps.

How to hide files in a jpg photo


1) Take two files -
one which you want to hide and another will be the jpg image(of any size and dimension)to hide that file

If you want to hide multiple files in one jpeg image, just zip them into one file

2) To make the process easy, Copy the above two files to the C:

3) Now open the command prompt (Go to start, Click "RUN" and type "cmd").

4) get to the root by typing cd\ or you can give the path name where the files are located

5) Now type the following command:

copy /b imagename.jpg + filetohide.ext new_image.jpg

6) Now a new file new_image.jpg will be created

7) Double click on the file and it will open the image which you used to hide the secret file

8) To access the hidden file simply change the extension from jpg to orignal extension of the hidden file,

Example: I took an image filename "myphoto.jpg"
I wanted to hide some important word documents so I zipped all the word files and created a zip file "word.zip"
Then copied both "myphoto.jpg" and "word.zip" to c:
Opened the command prompt
Typed the command: copy /b myphoto.jpg + word.zip new_image.jpg
Now I have a new file "new_image.jpg" in C:
When I double click on the new file it shows me the image of "myphoto.jpg"

If I change the extension of new_image.jpg to new_image.zip I can extract the contents of the .zip file

ENJOY !



ENJOY !

When scanning to ocr I get brccMCtl.exe has encountered .... and it shuts down. I can scan to email, file, and image. But Not to OCR. The Brother Control Center 3.00 is the problem.


I deleted all Brother programmes from by PC, cleaned the registry and used the Brother Uninstall programme first. (I restarted the PC after each deletion)
Then I reinstalled the latest Brother printer driver software without the PaperPort SE 11 programme.
Then I installed the Paperport programme separately.

It worked.

Thanks

Stand alone vb programme


yaa you can use the Setup Wizard from your VB for your project. It will make a setup for your project and will put all the runtime required files in a same folder, with your project executable with a setup.exe file. Copy all these files in any device like CD,DVD, Flash memo etc, in a same folder. And run this setup on any computer to which you want to install it.

Then your project will run on that computer.


Thanks

Text in CS2


Dear Roan,

It may be because your text is behind the background. That's what was happening to lots of people trying to use Photoshop CS2. Try going to Layer--then Arrange--then bring text to front.

This has worked for most of the people has fixed the problem. Hope thats helpful. If you still have problems you can go read the forums and also can access the help file in software's Help menu.
