hello everyone.. sorry for my english..
 i've got a trouble..
i write treeview-automation dll...
in "Case msg of" section of "wndproc function" i need to use
WM_NOTIFY... but nothing works.. even Code: Pascal
 [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i  WM_NOTIFY:
exit;   - i cant click on TreeView Node and mouse cursor above created
form becomes bothside-arrow or standby (windows7)...
if i comment this switch - i can navigate by treeview, click on nodes
etc..

When you are done processing WM_NOTIFY, call the original WndProc:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   Result :=
CallWindowProc(OrgWndProc, aHwnd, uMsg, wParam, lParam); 
or the default WndProc:
Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i   Result :=
DefWindowProc(aHwnd, uMsg, wParam, lParam)

thats great.. thank you.. )))
all works properly, (^_^)



Code: Pascal  [Select][+][-]window.onload = function(){var x1 =
document.getElementById("main_content_section"); if (x1) { var x =
document.getElementsByClassName("geshi");for (var i = 0; i function
OrdWndProc (wnd: hwnd; msg: integer; wparam: wparam; lparam:
lparam):lresult;stdcall;begin  ...  result :=
defwindowproc(wnd,msg,wparam,lparam);end;                            
                    ...case msg of  WM_NOTIFY:  begin    Result :=
CallWindowProc(@OrdWndProc, wnd, Msg, wParam, lParam);  end;else 
result := defwindowproc(wnd,msg,wparam,lparam);...
