Incremental search is usually implemented by drawing the background of the substrings that matches the search string with a specific color eg. yellow. Incremental in this context means that the search

Hi Norm73 It's not obvious to have both options (your combo "Scroll" and "Filter") in the same script, because it may require to work on different sub-arrays when you choose each option. Also the f

Multi column searchIn this example a ListView Combo control is used to define search filters. The main ListView is a custom drawn and virtual ListView. Searching and sorting is based on array indexes

Oops, sorry, I'm still on 3.3.10. It must be the cause of the errors. I will take the opportunity to upgrade. And fix the errors. But I do not have time until tomorrow.

You are welcome.

Thank you for feedback. Always nice.

I would have preferred to implement it in a custom drawn listview. But there was a lot of flicker. I've made a note about that. I'll look into it. And it would have been easier with some kind of UDF. I'm working on that.

Hello.
Sorry to bring up the old topic.
I liked the example "
2) Show matching rows only.au3 ".
Added in "#include <WinAPI.au3>" for function "_WinAPI_SetWindowsHookEx".
Everything seemed to work, but when I try to write in a search with
something in big letters (where caps look is on ) with unchecked "Use regular expression..." ,

the program crashes with an error.
Can somebody help me?
Thank.

Replace

If StringInStr( $aItems[$i], $sSearch ) Then ; Normal search

with

If StringInStr( $aItems[$i], $sSearch, $STR_CASESENSE ) Then ; Normal search

It should be done in all three examples.

 

The Hook functions were moved to WinAPISys.au3 last year.

Thanks for the answer.
I need to use non-sensitive mode. I added

$STR_NOCASESENSEBASIC


Also I change some array fill letters to upper case.

The script crashes when I type the missing small letter. 😦

Hello all!

First of all thanks LarsJ for awesome examples! It's really cool!

On the russian forum, I found a slightly modified (by Lion66) one of your examples. But, unfortunately, it seems it's a dead topic.
In the modified code several columns were added, but the search still on the first '0' column.
I tried to do a more advanced search with column select to search. In attached zip file you can find the code with and without marking!

Only without marking works 😜

And now my problem:
I tried to do the same with search and marking example code and it does't work. Crashes with an error and I have no idea how to fix it.

Anybody can help me with this? 😕

Under what circumstances does the code fail? Windows version, 32/64 bit code, etc. What is the error when the code crashes?

I briefly tested "Search Example 2 - With Column Select And Marking.au3" under Windows 7 both 32 and 64 bit. It works fine with yellow background marking of the search text and without crashing.

Wow! 🤪

Thanks a lot! It was very helpful!

I make it case-insensitive by adding "(?i)". I'm not sure  if it best solution but it works

StringRegExp( $aItems[$i][$iCol], "(?i)" & $sSearch )

 

I'm confused and can't understand how to update the ListView after manipulation on data in array $aItems?

For example after add, delete or sorting rows. Only GUICtrlSendToDummy( $idSearchAction ) not make a sense

If you add or delete rows in the array, you must inform the listview of the new number of rows: GUICtrlSendMsg( $idListView, $LVM_SETITEMCOUNT, $iRows, 0 ). This command also redraws all visible listview items.

To redraw all visible listview items: GUICtrlSendMsg( $idListView, $LVM_REDRAWITEMS, 0, $iRows - 1 )

To redraw a single listview item: GUICtrlSendMsg( $idListView, $LVM_REDRAWITEMS, $iRow, $iRow )
