It would appear, indeed, that the "etc" part of FORMATETC stands for et cetera (Latin for "and so on," or "and the rest"), as the FORMATETC structure contains a member specifying the format type along with members specifying 'other' information:

You should decorate the FakeNodeViewModel class with the System.SerializableAttribute for it be COM serializable:

As a general rule I always do a test run of the websites I want to scrape in scrapy. That means I use requests to make a simple HTTP get request. If i'm getting a status code error then it's easy to see, if I get the status code I want, I see if I can get the HTML I need.

1. First url https://seekingalpha.com/market-news/on-the-move requires headers to access the data, status code 403 when you do a simple HTTP request.

2. Second url https://seekingalpha.com/news/3594751-amd-swir-among-premarket-gainers requires javascript. So if I get a status code from the requests package, the next step does it have the HTML I need? In this case it didn't. I then will proceed to disable javascript, and you can see in this case, despite how simple the page is, it is entirely javascript.

So those are the two challenges with the website. The first is easy to get around, you can grab the headers by navigating to the network tools of chrome or any other browser. Look for the document request and grab the headers.

The second challenge I was unable to find a useful HTTP request, so indeed using splash was needed.

This is what I have come up so far:

explode time variable which comes from database first.assume my variable and value is

First off, you're right to state that you have a type mismatch. The Clipboard Formats are unsigned. Let's take one value:

-16230

Treated as a signed WORD, this is

0xC09A

This isn't too surprising. The documentation for RegisterClipboardFormat says this:

Registered clipboard formats are identified by values in the range 0xC000 through 0xFFFF.

The other possible values are mentioned in the documentation for the clipboard formats:

An application can identify a private clipboard format by defining a value in the range CF_PRIVATEFIRST through CF_PRIVATELAST

CF_PRIVATEFIRST through CF_PRIVATELAST map to 0x0200 to 0x02FF.

Clearly you're seeing one of the registered clipboard formats. To see what type it really is, you need to call GetClipboardFormatName when you encounter the value. It could change from time to time, since these are values that are handed out as different components register their clipboard formats.

When DoDragDrop is not called on the mouse down event, mouse is captured and mouse up event is received. But when DoDragDrop is called, QueryContinueDrag is endlessly called and I don't get the mouse up event, even after I released the mouse.

You don't get a mouse up event because DoDragDrop() blocks your UI message loop until the drag operation is completed. So you need to use the input flags given to your QueryContinueDrag() implementation to decide whether to continue dragging, perform the drop, or abort the operation.

If you start the drag on a left mouse down, return S_OK if the grfKeyState parameter includes the MK_LBUTTON flag, and return DRAGDROP_S_DROP if the MK_LBUTTON flag is cleared. Return DRAGDROP_S_CANCEL if the fEscapePressed parameter is true. This is documented on MSDN:

IDropSource::QueryContinueDrag method

Parameters

fEscapePressed

Indicates whether the Esc key has been pressed since the previous call to QueryContinueDrag or to DoDragDrop if this is the first call to QueryContinueDrag. A TRUE value indicates the end user has pressed the escape key; a FALSE value indicates it has not been pressed.

grfKeyState

The current state of the keyboard modifier keys on the keyboard. Possible values can be a combination of any of the flags MK_CONTROL, MK_SHIFT, MK_ALT, MK_BUTTON, MK_LBUTTON, MK_MBUTTON, and MK_RBUTTON.

Return Value

This method can return the following values.

S_OK
The drag operation should continue. This result occurs if no errors are detected, the mouse button starting the drag-and-drop operation has not been released, and the Esc key has not been detected.

DRAGDROP_S_DROP
The drop operation should occur completing the drag operation. This result occurs if grfKeyState indicates that the key that started the drag-and-drop operation has been released.

DRAGDROP_S_CANCEL
The drag operation should be canceled with no drop operation occurring. This result occurs if fEscapePressed is TRUE, indicating the Esc key has been pressed.

Remarks

The DoDragDrop function calls QueryContinueDrag whenever it detects a change in the keyboard or mouse button state during a drag-and-drop operation. QueryContinueDrag must determine whether the drag-and-drop operation should be continued, canceled, or completed based on the contents of the parameters grfKeyState and fEscapePressed.

I get callbacks like QueryGetData(TYMED_HGLOBAL) or QueryGetData(TYMED_HGLOBAL, TYMED_ISTREAM, TYMED_GDI, TYMED_MFPICT, TYMED_ENHMF), but not for TYMED_FILE. Why isn't Notepad requesting that?

You can't use TYMED_FILE for CF_HDROP, you must use TYMED_HGLOBAL. And the content of the allocated HGLOBAL must be a DROPFILES struct followed by a double-null-terminated list of file paths. This is documented on MSDN:

Shell Clipboard Formats

CF_HDROP

This clipboard format is used when transferring the locations of a group of existing files. Unlike the other Shell formats, it is predefined, so there is no need to call RegisterClipboardFormat. The data consists of an STGMEDIUM structure that contains a global memory object. The structure's hGlobal member points to a DROPFILES structure as its hGlobal member.

The pFiles member of the DROPFILES structure contains an offset to a double null-terminated character array that contains the file names. If you are extracting a CF_HDROP format from a data object, you can use DragQueryFile to extract individual file names from the global memory object. If you are creating a CF_HDROP format to place in a data object, you will need to construct the file name array.

The file name array consists of a series of strings, each containing one file's fully qualified path, including the terminating NULL character. An additional null character is appended to the final string to terminate the array. For example, if the files c:\temp1.txt and c:\temp2.txt are being transferred, the character array looks like this:

c:\temp1.txt'\0'c:\temp2.txt'\0''\0'

Note
In this example, '\0' is used to represent the null character, not the literal characters that should be included.

If the object was copied to the clipboard as part of a drag-and-drop operation, the pt member of the DROPFILES structure contains the coordinates of the point where the object was dropped. You can use DragQueryPoint to extract the cursor coordinates.

If this format is present in a data object, an OLE drag loop simulates WM_DROPFILES functionality with non-OLE drop targets. This is important if your application is the source of a drag-and-drop operation on a Windows 3.1 system.
