[SOLVED] GUIRegisterMsg is not working

[kcvinu]

Hi all,

I am playing with GUIRegisterMsg function for learning it. This is my code. It is not working. The error msg is this

Variable used without being declared.:
$tNMHDR = DllStructCreate($tagNMHDR, $lParam)
$tNMHDR = DllStructCreate($tagNMHDR, ^ ERROR

I can't find lParam as a declared variable in _GUICtrlListView_Create.au3 in help file.

Try adding it to the #forceref def...

[kcvinu]

@kylomas Already tried. But no way.

Create a small reproducer without all the fluff. You'll be surprised when you find out the problem was your end.

Typo

@guinness , Thanks for the inspiration. And i just avoid on fluff from this code. GUICtrlSetOnEvent function is the only one fluff i can found.

kcvinu,

Please shrink your signature - a spoiler seems indicated.

@Melba23 Done.

I meant Alert.au3 and all the other junk you have there. If you want help, then don't expect people to have to fix your reproducer for you. Try using _GUICtrlListBox_Create() instead.

@guinness, Success !. Thanks for pointing me to right direction.  I wonder why did this function changes for each controls. I mean, for ListView, it uses "WM_NOTIFY". For ListBox, it uses "WM_COMMAND".. Anyhow, i am decided to learn more on this stuff as soon as possible.
