I try:
Code:
     
     invoke  GlobalAlloc,GMEM_MOVEABLE,1024
     invoke  GlobalLock,rax
     push rax
     invoke     SendMessage,[FEDITHwnd],dword FEM_GETPOS,  rax,0
     pop rax
    


But this not help. FEDITHwnd still crash

Strange why not crash invoke SendMessage,[FEDITHwnd],WM_GETTEXT, 0,MyTextData
But crash invoke SendMessage,[FEDITHwnd],FEM_GETPOS, MyPosData,0

What is FEM_GETPOS? Since it's not a Windows builtin message, you have to do marshalling yourself for pointers.
