Hi BPak,

If you have a look at the commctrl.inc file, int the  ..\GoAsm\Include folder, you will see that LV_COLUMN is defined as follows:

LV_COLUMN Struct
    mask DD
    fmt DD
    lx DD
    pszText DD
    cchTextMax DD
    iSubItem DD
    iImage DD
    iOrder DD
EndS

So, the first member is mask in GoAsm, like defined in C for Windows, not imask. In MASM32 this member has been changed to imask (I guess) because mask is a MASM reserved word.

Just replace imask with mask and the problem is solved.

Regards,

Ramon
