If you’re going to ask someone to do your homework for you the night before it’s due, at least try searching for it online before you post! I will give you a clue; there is an article here on CP that covers this.
Or maybe we're trying to help you help yourself. You won't learn anything by being given the answer. Do you think the regulars here learned by being told how to do everything? If you don't understand what you're doing, then learn. There's plenty of resources and as Nick said, there's even an article here on CP about Blowfish encryption using C#.
I just find it slightly strange that you don't even know where to start and yet you are trying to implement blowfish encryption in C#, the night before none-the-less. Did you find the article here on CP?
P/Invoke the SendMessage native API and send the LB_SETITEMHEIGHT (0x01a0) message to the CheckedListBox's Handle.
If you override CreateParams and set the LBS_OWNERDRAWVARIABLE (0x0020) style, then specify the item index in the WPARAM parameter (3rd parameters to SendMessage) to set just a single item's height, otherwise the height is set uniformly for all items.

I am working whit a Accses Database & C#
thanks allot to all...
Poll your database every few hours (whatever you like, with a resolution of less than a day to be safe) for birthdays occuring within a certain period, then display those in a form that you can show (using either Show for a modeless dialog or ShowDialog for a modal dialog, but don't forget to dispose the modal Form when you're done using it since it doesn't get disposed automatically in that case).
Whichever one you want. They are both hosts for MSHTML, but the Web Browser component (an RCW around the IWebBrowser2 implementation for IE) provides more services than MSHTML itself, such as hyperlink resolution and additional methods. Using the AxWebBrowser component (the actual class that's generated, which derives from AxHost) also allows you to embed your report in a form, while using the ShowHTMLDialog helper API from MSHTML does not.
Global variables are generally a sign of poorly thought out design. However there are cases when you want to make something available to classes across your application (like values from the application's config class).
I would suggest a couple of approaches:
1. Is to make the variable available through a static property of an appropriate class.
2. Is to make a class (a singleton) that exposes these values through static properties. For instance a Config class that retrieves the information from a config file and exposes them to the rest of the application.

I have MFC Dll with dialog, I used it in C# App.
It's working functionality, but
The MFC Dialog stays grey. (Missing WM_PAINT (?
I think that I have problem with window handle.
Can U help me?
Can you give us a code fragment of how your C# code invokes the MFC built dialog/control? There are plenty of things that can go wrong. Without more information its purely conjecture on what to do to fix it.
The Code in the C#:
export static int Init(CallBack* xxx, SData* ps);
The function get delegate to return event from the DLL and data on the application. ( name and ID, not window handle or other data like it)
Sorry I forgot an essential point.
All the function (from App to the Dll ) was at other Thread ("Dll thread").
Not in the main (GUI) thread, but in the same one (using queue)
The init(…) and other function first enter to Q and the pulled by the "Dll Thread")
