I have created the Data access Logic component and when I execute the DALC an error occured like this "Cannot implicitly convert type 'x' to 'y'. An explicit conversion exists (are you missing a cast?) "
This error occured while I was trying to insert the records in the DB through the DAL component.
plz help me if anyone know the solution for this. Reply me as soon as possible, its very urgent....
Thanks in advance.

These type of questions make my headhurt.
They exception message tells you everything you need to know.
Somewhere you are trying to convert one object to another.
The fact that it tells you an explicit conversion exists, means you can type-cast it.
Go to the offending objects and type cast one to match the object you are assigning it to.

You really should invest in a good C# book.
This is basic stuff that should be covered in the first chapters of any programming book.
Check out the MSDN library if you cannot afford a book. There are lots of tutorials and every topic is covered.
For instance Casting using C# is covered here.
Cheers!

Hello,
I saw on a couple of recent posts people saying that casting the return
value of malloc is bad, like:
d=(double *) malloc(50*sizeof(double));
why is this bad? I had always thought (perhaps mistakenly) that the
purpose of a void pointer was to cast into a legitimate date type. Is
this wrong? Why, and what is considered to be correct form?
