I know that C++ is used on OSs like Unix, but is there a way to have VC++ compile my apps rather than have to copy it to the target machine every time. Is there an add-on that allows the creation of Linux, MacOS apps using VC++ 6?
I'm not late, I'm just not as early as I could have been.

No, VC6 is very much a Windows only compiler.
VC 4.2 used to have an add-on to compile MAC OS apps but Microsoft discontinued that a long time agon.

So the only way to make an app for MacOS is to use a Mac and get a software compiler for the MacOS.
Are there no freeware/sharware/commercial products for a windows machine that compiles and links a MacOS App?

CodeWarrior is the main C++ compiler for the Mac. It might do cross platform compiling. Other than that you'll have to develop Mac apps on a Mac.

If you truly need to support numerous environments with a gui app, your best bet is to buy a cross platform development library and code to that rather than MFC. At one of the telcos I worked at, they were using ZApp for that purpose (personally, I hated the constraints since the product I was working on was Windows only and MFC was more familiar).
Do a search on the net for cross platform libraries and you'll come up with a number of solutions that cover Windows, Mac & Unix.

Hi,
I want to encrypt the password & store it in registry.Also i should be able to decrypt the string.
How can i do that?
|
|
|
|

There are a few libraries available on
the net that contain ready made encryption functions..
One of the more popular ones is called cryptpak or
something similar, and contains quite a few popular
encryption algorithms like DES, Blowfish etc.
Or you could write your own encryption functions - try
searching for encryption algorithms on google and you
should find a few sites that explain the basics of how
to write code to encrypt data.

There are several Crypto articles here on CP. Also Windows includes Crypto functions. And finally look at Crypto++ http://www.eskimo.com/~weidai/cryptlib.html

I've only seen the one implementation on CBlowFish...perhaps you could direct me to another...?

Do an Article search on Crypt. Also look at codeguru.
Here's a few:

BTW Crypto++ rocks. Can't comment on these articles though as I've not read them.

For a different approach, consider this... I never use encryption for things like Passwords in applications: instead, I use a one-way hash (like MD5) and store the hash instead.
So basically, when the user sets a password, you take the password, calculate a hash from it, and store the calcualted hash value in the registry/database/wherever/whatever.
Later on, when you need to verify a password, you take the entered password, calculate a hash from it, and then compare it aganist the previously stored hash value.
BYW: This method also allows you to use passwords of any length, because the hash value (in the case of MD5) is always the same length.
Peace!

I am looking for a way to display system date and time in my Win32 application?? any suggestions.

You can use GetSystemTime and/or GetLocalTime

Also if you happen to be using MFC you could use CTime.

Thx for the response. Now, if I have to keep displaying accurate time, I will have to invoke a thread to repeatedly update it, right?? Please tell me if I am thinking on the right lines

Yes, that's what you'll need to do. Need not have a separate thread. Just start a timer.

When updating the displayed time, be sure to update the displayed string only if it's (the string) different. Otherwise you'll see unnecessary flicker. If you're using a timer (as Nish suggested), set the interval to slightly less than one second.

Wont setting the timer to less than a sec. hog up CPU and my program might not be able to do anything else?? or is it ok??
|
|
|
|
|
No it won't hog up the CPU. WM_TIMER are among the lowest priority messages and are automatically compacted by Windows. That is, if you receive 4 WM_TIMER messages for the same timer, Windows will automatically compress them into a single message. Try it, you'll see!
