Hi at all.

*lol* I really know how to switch my screensaver on and off.

I need this procedure for my backup tool. One of my users got a problem, while a backup is running. If the screensaver turns on (with password activated), the backup stops. After entering the backup will continue. This is ...

Hi there.

Does anyone knows how to prevent the sleep mode or screensaver while a program is running?

On MSDN I found this: http://msdn.microsoft.com/en-us/library/aa373208(VS.85).aspx .

I thought: Thats it. But it won't work. PB won't accept the API-Command.

Here is my testcode:

Hm....

But if you have a AES256 crypted file. Generated by anyone. How will you decrypt it without knowing the length?

For my work I can solve this by saving the length for any crypted string or setting the length to a virtual value like 1024 (the max lenght I would crypt ;) ) This works fine too ...

Maybe it is easier to understand if I copy the code:

In your AES.pbi you show an example using My question is:
How can I know the "neededlength" if I did not crypt the text?

Hi Inf0Byt3.

Thanks for you lib.
Works fine for me.

But I have one question left:
In your example, you decrypt a string you crypted before. To decrypt, you need the "neededlength" witch was calculated befor crypting the string.

If you just want (or later want) to decrypt a AES-crypted string, you ...

Hi there.

First, big thanks to JCV for the great libs.

It would be very nice to have a example for the AES. I need to crypt strings. An example is missing ... :roll:

Can someone code one?

Hi out there.

Does anybody knows how to change the date of a directory, like the SetFileDate() does with files?

If I create a directory using CreateDirectory() it always has the date of creation. I need to change this.

May someone help me?

Really nice code. But if there is a change or modification in a subdirectory, your code won't work, right? So you can't watch C:\ (including subdirs)...
