Before I go digging into it, I was wondering if there were any examples on dragging files between two CXTShellListCtrl objects. Do any exist? If not, then what are the steps. Do I have to register a drop taget, etc... ? Thanks,
Larry

I figured it out. The answer is to derive a class from CXTShellListCtrl and add the following code: BEGIN_MESSAGE_MAP(CShellListCtrl, CXTShellListCtrl) ON_WM_DROPFILES() END_MESSAGE_MAP()
void CShellListCtrl::OnDropFiles(HDROP hDropInfo){ TCHAR strSourceFilename[_MAX_PATH]; int nFiles = ::DragQueryFile(hDropInfo, (UINT)-1, NULL, 0 );
for ( UINT i = 0; i < nFiles; i++ ) {
::DragQueryFile(hDropInfo, i, strSourceFilename, _MAX_PATH); // Insert copy file code here }
::DragFinish(hDropInfo); } |
