how to drag and drop to desktop

[rolfk]

One more note: After you created your IDropSource and IDataObject you will probably want to use DoDragDrop() from ole32. This function will sit there and wait in a loop until the user has finished the operation either by dropping the object somewhere or by canceling it.

You might be able to create the IDataObject through a shell API from the file path but there is probably no way around implementing your own IDropSource COM object yourself.

Hi jeyanthi,

here is an example how you can drag and drop from a ListBox in LabView to your Desktop. It works without additional c files, only with the windows API. It´s only a short example.

Hope it helps.

Nice work!
But putting this into a DLL wouldn't be more work really. (If you know how to operate a C compiler which you Mike most probably do judging from the VIs. It's definitly not a trivial exercise to do it all in LabVIEW.)

Also I wonder if at least part of the middle loop couldn't be avoided by using the Drag Starting(?) event in LabVIEW.

Hi rolf,

yes you are right, there is definitely a better way to do it. This should only show that it is possible.

can i  have 8.0 version  example

[MikeS81]

Hi jeyanthi,

here it is for LV80. You have to clean the errors, because there are some differences between LabView 8.5 and 8.0 in calling a dll.
