I would like to add roots to a VirtualTreeView http://www.delphi-gems.com/index.php/controls/virtual-treeview with a thread like this:
function AddRoot ( p : TForm1 ) : Integer; stdcall;
begin
p.VirtualStringTree1.AddChild(NIL);
end;
var
Dummy : DWORD;
i : Integer;
begin
for i := 0 to 2000 do begin
CloseHandle(CreateThread(NIL,0, @ADDROOT, Self,0, Dummy));
end;
end;
The reason for this is that I want to add all connections from my INDY Server to the TreeView. Indy's onexecute/onconnect get's called as a thread. So if 3+ connections come in at the same time the app crashes due to the TreeView. Same is if a client gets disconnected and I want to delete the Node.
I am using Delphi7 and Indy9
Any Idea how to fix that?
