Hello!
I have a VB .NET WPF that searches a local directory structure to locate a few hundred files per month. These files need to be filed (drag and dropped) onto a 3rd party application that stores the files. The third party application has its own directory structure, and so the correct directory has to be picked before each file is dragged-and-dropped.
I am able to control the 3rd party program with SENDMESSAGEs. I can log in, select the correct directory, and read all the values from the 3rd party controls.
To manually do the upload, the user drags the file to the 3rd party control (which happens to be a ListView) and then the file gets copied to the 3rd party's file system.
Can I somehow simulate the drag-and-drop function after selecting the correct location in the 3rd party application? I tried WM_DROPFILES, but that didn't appear to do anything. However, I tried the same WM_DROPFILES into Notepad and it didn't do anything, either.
I found the Control.DoDragDrop method to initiate the drag-and-drop, but could not find a message to send to the 3rd party application to start the "drop" part of the process.
Thanks for any help!
