WM_PASTE is sended to an edit control or a combo box.
You are sending the message to the main window.

You have to find the child window

Use FindWindowEx function

If suppose an application window has two Edit control, then how to get handle of the second Edit control. I am able to get the Handle of first, but wondering how to get the next ?. Also i want to Simulate TAB key press, i.e after Edit control gets the text, then TAB key press should be done so it goes to next edit control. Please help and guide me through it. Thanks in advance.

is the application the target you want to past the text instead of Notepad?
HWND WINAPI FindWindowEx(
_In_opt_ HWND hwndParent,
_In_opt_ HWND hwndChildAfter,
_In_opt_ LPCTSTR lpszClass,
_In_opt_ LPCTSTR lpszWindow );

when you call for the first time FidWindowEx, you will get the handle of the first edit. You should call another time FindWindowEx using the result of the first call as the hwndchildafter parameter
