Dragging and dropping a .WAV from Delphi App to other apps
Is there an easy way to drag a .WAV file from a Delphi 2006 App to another app. It's not from a listbox or anything like that. It's from a custom window. My code would need to be responsible for generating a .WAV file based on where the person initially clicked on a window. Is the only way to drop a file from a Delphi 2006 to use complicated COM routines? If so, then would the other app that receives the file need complicated com routines too, or would it work with any app that could accept a the same dropped file type from Explorer? Thanks.

You need to write two classes that implement the IDropSource and IDataObject interfaces (or use third-party classes, such as from Anders Melander's Drag-and-Drop suite, http://melander.dk/delphi/dragdrop), and then your code needs to call the Win32 API DoDragDrop() function when it detects that a drag&drop operation needs to take place. The IDataObject object needs to contain information about the .WAV file and its contents. Any app that implements the IDropTarget will then be able to accept the drag and extract the data as needed. > Is the only way to drop a file from a Delphi 2006 to use complicated > COM routines?

Windows Explorer uses the same kind of COM routines for its own drag-and-drop operations. IDropSource, IDropTarget, and IDataObject are the preferred way to drag/drop data around in Windows. -- Remy Lebeau (TeamB)

Thanks for the reply. I tried that toolkit and it works. I'm wondering if you there might be a way to have my app drag and drop a file onto another app but render the file at the time the file is dropped rather than the file needing to already be written to disk at the full file size before initiating the drag and drop?

You can try to use other than file references in OLE drag&drop. It only requires that both the sender and receiver can handle your object type. DoDi

In general, the IDataObject that is passed around during the drag&drop
operation needs to include CFSTR_FILECONTENTS and CFSTR_FILEDESCRIPTOR
items, where the CFSTR_FILEDESCRIPTOR contains descriptive information about
the file (filename, size, etc) and the CFSTR_FILECONTENTS contains an
IStream or IStorage object that provides the actual file data. That way,
you can store your data anywhere you want (in memory, in a database, etc),
and pull it out on an as-needed basis when the target of the drag&drop
operation actually tries to read it. Refer to MSDN for more details:
Shell Clipboard Formats
http://msdn.microsoft.com/en-us/library/bb776902.aspx
Handling Shell Data Transfer Scenarios
http://msdn.microsoft.com/en-us/library/bb776904.aspx
I don't know how to accomplish that with Ander's toolkit, though. You would
likely have to make use of the TFileGroupDescritorClipboardFormat and
TFileContents...ClipboardFormat (such as
TFileContentsStreamOnDemandClipboardFormat) classes, but I don't know how
exactly.
