Hello Everybody,
  What I don't get, This was working before:

constant FILE-{"afile.dat","bFile.dat",cFile.dat"}--etc...
constant ListView15 = createEx( ListView, {"ListView15",""}, Window1, 184, 56,
160, 200,
 w32or_all({LVS_REPORT,LVS_SHOWSELALWAYS}), 0 )
atom lvMask 
integer lvOk 
lvMask = w32or_all({LVS_EX_CHECKBOXES})
lvOk = sendMessage(ListView15,LVM_SETEXTENDEDLISTVIEWSTYLE,lvMask,lvMask)

procedure load_controls()

  for x=1 to length(FILE) do
        VOID=addLVItem(ListView15,0,FILE[x])
       
      end for


setCheck({ListView15,3},w32True)
end procedure

Now I keep getting error:

F:\eu\WIN32LIB\Win32Lib.ew:22844 in procedure setCheck() 
variable row has not been assigned a value 
    pControls = {13,3}
    flag = 1
    hMII = <no value>
    lType = <no value>
    id = 13
    row = <no value>
    TV_ITEM = <no value>
    state = <no value>
    lFlags = <no value>
    mask = <no value>
    k = 1
    i = <no value>
    j = <no value>



row IS declared it's 3, I don't get it.

Any help appreciated.

Thank you Guillermo,

But I am doing that.

setCheck({ListView15,3},w32True)--the list view and row 3 in funny brackets.


I see you you have put setCheck in funny brackets. Is that on purpose for this
to work?

Anyway I fixed my problem by using setLVCheck(ListView15,3,w32True).


But it should work with setCheck also.

Thanks Guillermo,

  But that's what I got,

setCheck({{ListView15,3}},w32True)

And I still get the same error row is not defined, But it IS. It's 3.
