I have created a personal application in c++ using wxwidgets and native win32 api..
It shows list of files in listbox. when user click a file and then click play button, the application searches vlc player window and sends WM_DROPFILES message with DROPFILES structure. This way vlc player should open and play the file.
The problem is that if I send the window message to notepad window instead of vlc player window for testing, it successfully opens the dropped file. but its not working for vlc player window opened. Please help.
