Sounds like you need to start by learning how to make crystal reports. I suggest following a few tutorials[^].

You need to set the padding on the RijndaelManaged object. Checkout this code project article which explains all about the padding issue Cryptor - Encrypt Files With Rijndael 256 bit[^]

You do realise that your code isn't C# don't you? I can't read the sample either because it is too spaced out - please use the <pre> tags around the sample code and format it so that it can be read.

Well, you've got an event handler here, axWindowsMediaPlayer1_CdromMediaChange. Does it get called? Do you have a hookup on the event, e.g.

axWindowsMediaPlayer1.OnCdromMediaChange += new CdromMediaChange(axWindowsMediaPlayer1_CdromMediaChange);

Are you sure the event is being fired? Put a break point inside the event handler and step through the code. I don't see any obvious mistake in the code.

Hi. I need to find the location and size of the taskbar within a Windows environment so that I can finish some coding in a windows forms configuration library that I have built based on some code that I originally got from another Code Project post. What I specifically need to know is the bounds of the Primary Screen not including the taskbar if it is displayed and locked.

Is there are .NET Framework class for that will provide this or will I need to go to the Windows API? My searches thus far in MSDN and here have not been helpful.

Any help greatly appreciated. Thanks.

Take a look at Screen.WorkingArea[^];

Gets the working area of the display. The working area is the
desktop area of the display, excluding taskbars, docked windows,

Use the ISO format installation package[^].

If you've never worked with iso image files, there's some info here[^].

It looks like they copied the same info from the online installer.

But Now I have a problem installed SQL Server 2008 64x on Windows 7, the installer show me some mistakes like can't install the Database Motor.

Again Thanks very much.

I'm not sure about that one. I'm using SQL Server 2008 on
Windows 7 and I don't recall any install issues. I did
install it before Visual Studio so I wouldn't get 2005,
however. Is there another version installed?

I didn't say that. I meant I use SQL Server 2008 x64 on
Windows 7 x64 with no issues. If you're on Windows 7 x86
then you'll need to use the 32-bit SQL server.
