Hi gnozal.

Maybe it's a feature request, you'll see.

I use with pleasure the PureLVSORT library.
But my needs are somewhat complex : I would want to filter a column with several words, spaces (or whatsoever) separated.
To achieve this behavior, I copied your source code example from the help file (PureLVSORT_LoadListIconFromMem() page) and adjusted it to my needs.
Here is it :

Code: Select all

Global *OriginalListBuffer
Procedure MyFilterCallback(GadgetNumber.l, FilterString.s, ListIconColumn.l, EventCode.l) ; simple filter example
    If EventCode = #PureLVSORT_FilterBtnClick
        FilterString = Trim(FilterString)
        If *OriginalListBuffer
            PureLVSORT_LoadListIconFromMem(GadgetNumber, *OriginalListBuffer, "", ListIconColumn, #True)
        EndIf
        If Len(FilterString) = 0
            ProcedureReturn
        EndIf
        *ListBuffer = *OriginalListBuffer
        SpacesCount = CountString(FilterString, " ")
        WordsCount = SpacesCount + 1
        For w = 1 To WordsCount
            Word.s = StringField(FilterString, w, " ")
            If *ListBuffer
                PureLVSORT_LoadListIconFromMem(GadgetNumber, *ListBuffer, Word, ListIconColumn, #True)
                *ListBuffer = PureLVSORT_SaveListIconToMem(GadgetNumber)
            EndIf
        Next
    EndIf
EndProcedure
;
#Window_0 = 0 
#ListIcon_0 = 0

    If OpenWindow(#Window_0, 216, 0, 602, 302, "PureLVSORT Test",  #PB_Window_SystemMenu | #PB_Window_TitleBar | #PB_Window_ScreenCentered)

EndIf
End

The principle is simple : I slice the phrase into words and for each word, I filter the current content of the list.
In this adapted example, if you type "a r", it should return some rows (exactly 6).
Except that it returns nothing.
Furthermore, if I blank the filter in the filter field, the list stays empty.
This last behavior exists also in your original example : this is because the FilterString parameter contains some weird chars, I don't know why.

An aside on your help file : in the PureLVSORT_DefineFilterCallback() page, you talk about "#HDN_FILTERCHANGE or #HDN_FILTERBTNCLICK events." and in your original above example, the code refers to "#PureLVSORT_FilterChange"; in my adapted example, the code refers to "#PureLVSORT_FilterBtnClick".
Is it a mistake ?

Thank you for your attention.

There is an issue with Windows Se7en, posted by QuimV, which tested a lot of code on his Win7 machine (thread : http://www.purebasic.fr/english/viewtop ... &start=277).
We found out that it's an issue with the API function SendMessage_(hHeader, #HDM_GETITEM, *pNMHdr\iItem, @hHDItem)
In Windows XP :
When len(filtertext)>0 the function returns 1
When len(filtertext)=0 the function returns 0
In Windows W7 :
When len(filtertext)>0 the function returns 1
When len(filtertext)=0 the function returns 1, and there is garbage in the filter string...

According to MSDN, HDM_GETITEM returns 0 if failed...

These constants have the same values. I forgot to update the help file.

Ok for the 7 issue.
Tested on WinXP SP3 and it works fine, for the filter blank string.

But the other problem is still active.

I would want to filter the list with several words and the technique used (see code in my previous post) does'nt work for which I have no explanation.

Any idea ?

Up again.

For the Windows 7 issue, if you disable the Support XP Theme in your project properties, the bug disappears.

I do not fully understand your code, but I don't think it's possible / convenient to call PureLVSORT_LoadListIconFromMem() repeatedly to achieve want you want.
I would load the full listicon content and then parse each line, deleting a line it if it does not match the keywords. You can use #WM_SETREDRAW On/Off to avoid flickering.

So it seems to be a common controls issue.

When I include PureProcs_Execute() in my app, and then compile it, I"m getting:

is there any way to figure out what that means?
Or is this akin to the "string error" message when a library is out of date?

-- end --
never mind -- it turns out that it really meant "Access denied" (the target exe was running)
