Let's suppose you have a thread transfering some (Giga)bytes over an tcp/ip connection and another thread is waiting for this data. So this thread can use WaitFoSingleObject todo nothing in...

try handling the "wxCloseEvent" event for the main window. In your own handling method simply show the dialog and when the user clicks ok, call the destroy method. Otherwise do nothing and the main window remains working.

How about a wxTimer? Start it with the proper delay between the images. Redraw bitmap and restart the timer.

Hi,

Pointer have some advantages, in other languages you are using references. These are only some "special" pointers which can't be null. But sometimes a null pointer is very handy.

You need the include's for compiling. So, if you won't install wxwidgets, you must deliver include's (*.h) files and either static libs or dlls from wxwidgets. But building a wxWidget App without any wxWidgets file doesn't make sense. :?

Hi,

so the main reason for changing the wx version is the drawing problem in vista? Have you try 2.8.10? Maybe the drawing problem still exists under 2.9.0? Have you tried to fix the drawing issue?

try this:

http://www.cryptopp.com/

this lib can easily integrated in wx apps and has a lot of usefull things, like encryption, hash functions (the checksum you are looking for) and other nice things like base64 encoding/decoding.
