You can post this on my CP profile instead of posting here Smile | :)

can't you display original image and by using a simple encryption function, convert the bitmap bits to to encrypted format and then save? I'm not sure whether I'm talking about your problem Smile | :)

Yes I shall...
But today im a bit busy.
Seems you can so some stuffs with showing and saving an image. that's quite simple. you will get lot of information from the web itself.

On reading and writing to file, the real logic occurs.

You can make use of GetBitmapBits and Set bitmap bits. or directly modifying the bitmap buffer wtih your XOR logic.

ok try your level best.

So what exactly are you having difficulty with? Encrypting an image, displaying an image, or saving an image to disk? Three different questions require three different answers.

i'm doing this project whereby,

i have a "load" button that enables me to display a picture in bitmap format...
Next i have to encrypt the picture and display it again..

and decryption as well in future

Thanks

Well, there's CRAPI, and then there are these:

What is the difference between

#include (iostream.h)

and

#include (iostream).

Are they different? If so, what are their differences?

In the new C++ lib there are some differences . For ex
1)open functions do not take a third parameter (the protection parameter).
2)You cannot create streams from file handles. etc....

Somethings seem HARD to do, until we know how to do them.

I think iostream.h is keept for backwards compatibility, all the old and new stuff is in iostream, don't know why they switched.

Just FYI: They didn't switch. The .h versions were non-standard. That is, they were what everyone used before there was a standard. The problem was that each system implemented them slightly differently. When the standard was released, most systems kept the .h versions for backward compatability. They are now being phased out of almost all systems completely.

Hey all,
I have two differnet projects coded in VC++6.0 version. I want to merge both the projects. How do I do it?

ie., Project2 needs to be included in project1. Can the project as a whole be added or just the files, say, include the cpp and .h files from project2 in to project1?

What is the best way to do it?

Any ideas/help please?

Thanks in advance,
Anusha.

Basically, a "Workspace" in Visual C++ 6, or a "Solution" in Visual C++ 7.0 ~ 8.0, is what for holding one or more projects.

thanks for ur response.
But If I include my project2 in my project 1 workspace, then I understand there can be two projects in one work space.
But What I need is to use .cpp and .h files from project2 in project1 and build them or can I build the two projects together?
Basically my project2 is dialog based and project1 is single document.

I want to use the project2dlg.cpp and project2dlg.h and all the relevant files that is dependant in to my project1.

Is htere a way I can do it or should I recode my project1 accordingly to just include the files n functions that I want from project2.

Hope this is clear. If u need any furhter info. please let me know.
Thanks.

Choose your project1 and then do a "add files to the project", point to the files you want to be part of project1.
