Hi again Euman

I renamed "buffer" to "gp_buffer", but not work...

Below the error reports:

C:\11USRE\DIR\EFFM.exw:294 in function myalloc() 
A machine-level exception occurred during execution of this statement 
    size = 256
    mem = <no value>

... called from C:\11USRE\DIR\treeviews.ew:145 in function filltvitem()  
    id = 1639430
    Item = 6371360
    mask = 1
    state = 0
    path = <no value>

... called from C:\11USRE\DIR\EFFM.exw:907 in function WndProc()  
    hwnd = 984176
    iMsg = -405
    wParam = 0
    lParam = 522132
    i = <no value>
    j = <no value>
    k = <no value>
    j = <no value>
