How to drop a file out of a zip-file to my NGDropTarget

Martin Pflug

Hello,

i open a zip-container direct in windows explorer.

Now i want to drag one or more files out of the zip-container and drop it at my NGDropTarget.

So far, so good ... and now? I want to copy the dropped files out of the zip-file to an own folder.
I don't know the way to go further.

Is there an example as source?

please give me a help.

Thank you

Martin

You should first enumerate dragged file formats (using the demo), and look whether some built-in formats are present. Then - use corresponding format functionality (if any, I guess "virtual file" format shuld present).

OK, i think you mean the Demo.exe 

Is there a demo also as source?

The result of the demo is:

• Shell IDList Array
  
• FileGroupDescriptorW
  
• FileContents
  
• UsingDefaultDrawImage
  
• DragImageBits
  
• DragContext
  
• DragSourceHelperFlags
  
• InShellDragLoop
  

oh, my knowledge at DragDrop is so poor ... you mean FileContents, right?

Demos sources should be placed somewhere inside wour installation folder. Please check it along with documentation about formats and how to use them:
