Dear All,
Please let meknow how can I encrypt a string and store the encrypted string in database, then reterive the encrypted string and decrypt it.

thanx

Depends on how strong the encryption must be.
The easiest and most fun Smile | :)

way is XOR encryption. I'm sure you'll find plenty of information and examples on the web.

I usually develop my own encryption methods, two methods to encode and decode using very basic ways, like getting the integer value of the string, play with it, store it. Do the opposite when retrieving it.

How can I disable dots from studio.net2005 editor

The biggest problem with crypto is keeping the secret secure.

There are plenty of libraries available that will do Rijndael/AES. Including some stuff that ships with .Net

I've used the .net libraries a few times in the past, although if i could find a properly peer reviewed open source verison i'd be much happier using it.

XOR should only be used for the very lightest crypto requirements, it's very oldhat and can be easily broken.

I suppose it depends what you want to do. XOR will hide your girlfriend's phone numbers from your wife but it wouldn't hold up very long against the forces of the RIAA trying to prove that you once looked at a copy of that DVD key.

I've never seen that before. Perhaps the Visual Studio will be suitable for this question.

good editors have the option of showing characters that normally are hidden,
such as space, tab, carriage return. It exists in Word, in Visual, etc.

The first step is to define the format of the text. I presume this will be a text file that will have to be read back in at some point.

1. First decide which all properties you want to save to the text file.
2. Create a structure for holding data for the shape using these properties.
3. Design the structure in such a way that it will cover most common properties for all shapes.
4. When you draw the shape, copy the values to the instanece of structure.
5. Finally write the structure to the file.

How about this?
