Hi there,

I want to create a sub to select all checkboxes of the listview at once, and another for unselect at once too, but I have not succeeded yet.

Can someone help me please ?

The source program is as follows:


'ListView Report Example

Hello Pedro,

I am a little puzzled by your question. Apparently others feel the same because of the lack of responses on the LB Conforums where you cross-posted this question. Your subject and the demo code you posted seem to have no relation to one another because the demo shows no check boxes.

The following demo is my guess as to what you want. Please let me know if I am wrong.
Code:
  NoMainWin
  Call InitCommonControls
  Button #1.btnChecked, "Check All", [CheckAll], UL, 185, 10
  Open "ListView Check Demo" For Window As #1
  #1 "TrapClose [Quit]"
  dwStyle = _WS_CHILD + _WS_VISIBLE + _
        1 + 4 + 8 + 32768 'LVS_REPORT + LVS_SINGLESEL + LVS_SHOWSELALWAYS + LVS_NOSORTHEADER
  hLV = CreateListView(_WS_EX_CLIENTEDGE, dwStyle, 0, 0, 175, 150, hWnd(#1), 0)
  dwStyle = 4 + _ 'LVS_EX_CHECKBOXES
            32    'LVS_EX_FULLROWSELECT
  Call SetExtendedStyle hLV, dwStyle
  Call InsertColumn hLV, 0, "Numbers", 150
  Restore [Data]
  Read N$: I = 0
  While N$ <> "EOD"
      Call InsertItem hLV, I, N$
      Read N$: I = I + 1
  Wend
  Wait
  [Quit]
  Close #1
  End
  [Data]
  Data "One", "Two", "Three", "Four", "Five"
  Data "Six", "Seven", "Eight", "Nine", "Ten"
  Data "EOD"
[CheckAll]
    Call SetChecked hLV, -1, 1
    Wait
  Sub InitCommonControls
      struct LVCOLUMN, _
          mask As ulong, _
          fmt As long, _
          cx As long, _

The code I posted today is not the same code posted on the Conforums. Please notice the addition of a Sub SetChecked, which takes the following parameters: hLV, the handle of a ListView control; item, the index of the item you want checked or unchecked, or -1 for all items; and checked, a flag to indicate whether the item should be checked (1) or unchecked (0).

Thank you very much for all code provided. You are amazing.

Finally, you could generate a api code to create gridlines in this listbox.

Thank you very much.

Pere.

Gridlines are an extended style of ListViews. You just need to get the value of the constant LVS_EX_GRIDLINES, which happens to be 1, and add it to the dwStyle argument passed to SetExtendedStyle in the code I posted previously.

If you want to use these fancy controls, you should really take the time to understand the basics. All the information is on MSDN. Well, most of it--I usually Google for the values of constants that LB lacks. For example, I searched for "define lvs_ex_gridlines". Of course, you need to understand some C syntax to know how to translate it to LB.

This is easy, since Brent provides a translation table at Converting C types to LB types.

At the top of each page is a gray bar, which contains links to more information, see the Hints section for more useful information.

I'm not exactly sure I understand, but if you want to know which item was double-clicked in a ListView, it requires some sophisticated programming. You have to use my WMLiberty DLL, a callback function, and some pointer manipulations.

I have a demo at www.b6sw.com/forum/content.php?mode=snips2&t=443.
