Hi I’am a begainner in this vb and I don’t know how to use API, I need some one to explaine the following code as an example and if there any books or websits that explaine API please tell me

Private Declare Function SendMessage Lib "User32" Alias "SendMessageA" (ByVal hWnd As Long, ByVal wMsg As Long, ByVal wParam As Long, lParam As Any) As Long

i have many codes using api, but i can not creat one, this is my problem ..

Go here you can download a newer API Viewer and an API-Guide which will show all API calls with a description and example.

I think what that comand does, is send a command to somewhere else. For example: when you click and drag on the form, you can send that message to the Form Title bar, and it will act like you are dragging from the title bar. I don't knoe if this helps you any.

Jabstract: Don't just imagine, make it happen!

That command sends a message to the corresponding window, such as telling the window to close, or pressing a button, it is also possible to change the text of a window using that API call.

I would suggest you buy or borrow VB6 for dummies by Wallace Wang. He has examples on a disk located in the back of the book which show you how to use API calls. Plus having a book is always good for reference, sometimes I even consult one of my books.
