Hi all,

I have a MFC dialog C++ application in VS2010, And my application has two textbox is source folder(txtSrcfolder) and destination folder(txtDesFolder) so when I drag and drop a file to txtxDesFolder, I want to assign full file path to txtDesFolder and the same to txtSrcFolder.
But how to determine which textbox is draged to?
(if there is only one textbox i can handle it but with many control I can't)

Can you help me, please?

Try to pass a box pointer to this test Smile | :) :
/*static*/ bool CYourDialog::TestDropWnd(CWnd* pcWndTest)
{
  CPoint cPoint;
  if (::GetCursorPos(&cPoint)) {
    return (pcWndTest == CWnd::WindowFromPoint(cPoint));
  }
  return false;
}

At your "dropped" event, call this test for the both boxes (pass their pointers). The function will return true, if a testing box is under the mouse :)

so what will pcWndTest parameter be inputed? I am using CAppDlg::OnDropFiles(HDROP hDropInfo){} to get folder path

In the context of your dialog:
bool bDroppedOnSrcBox(GetDlgItem(IDC_SRC_BOX)); // IDC_SRC_BOX is the resource ID of the box
bool bDroppedOnTrgBox(GetDlgItem(IDC_TRG_BOX)); // IDC_TRG_BOX is the resource ID of the box
