I have a dialog (DialogBoxParam) with a ListView (SysListView32) and when i send it to tray and then i restore the dialog the ListView is not "updated".

I have this in my project:

.ELSEIF lParam==WM_LBUTTONDBLCLK
invoke ShowWindow,hWnd,SW_RESTORE
invoke SetForegroundWindow,hWnd

I have also tried "invoke UpdateWindow,hWnd'.

Ideas?

Maybe this thread can help. Is is not quite the same problem but the solution might work for you also.

Perhaps you can make some minimal code that exhibits the problem and post it here. Then others may be able to help a bit more.

project.rc

CONTROL "",5000,"SysListView32",WS_CHILD|WS_VISIBLE|WS_BORDER|WS_TABSTOP|LVS_ALIGNLEFT|LVS_REPORT,5,14,339,105

project.asm

goes to tray:
...
...
.ELSEIF uMsg == WM_SIZE
.IF wParam == SIZE_MINIMIZED
invoke ShowWindow,hWnd,NULL ; SW_HIDE
invoke UpdateWindow,hWnd
.ENDIF

...

back from tray:

...

.ELSEIF uMsg==WM_SHELLNOTIFY
.IF wParam==IDI_TRAY
.IF lParam==WM_RBUTTONDOWN
invoke GetCursorPos,ADDR pt
invoke SetForegroundWindow,hWnd
invoke TrackPopupMenu,hPopupMenu,TPM_RIGHTALIGN,pt.x,pt.y,NULL,hWnd,NULL
.ELSEIF lParam==WM_LBUTTONDBLCLK
invoke ShowWindow,hWnd,SW_RESTORE
invoke SetForegroundWindow,hWnd
invoke UpdateWindow,hWnd
.ENDIF
.ENDIF
....

but the listview doesnt "refresh" at all (see image)

Have you tried InvalidateRect?

no.. but its strange why entire window (listview included) is not refreshing correctly with this code.

i will search the forum for an InvalidateRect example... thx

Just insert:

Code:

invoke InvalidateRect,hWnd,NULL,TRUE

Or, if you don't like symbolic constants:

Code:

invoke InvalidateRect,hWnd,0,-1

BTW: make sure that your hWnd is properly defined. It should assemble to [some_dword_address]. You may want to check that.

Code:

; General constants

NULL  = 0
TRUE  = 1 ; <<<< POSITIVE
FALSE = 0

Perhaps there is no API that checks for 1 exactly but I would stick to that value just to be safe.

I always use:

Code:

FALSE=0
TRUE = not FALSE

Seemed quite logical to me. But thanks for pointing that out.
