I am using wxwidgets 2.8.10 with c++ and I am using both windows xp and windows 7.
Is there any function to see if "pdf" software is available in my computer or not by using wxwidgets?

Presumably you want to know whether a PDF viewer is available in order to open a PDF document. And if this is the case, you should just try opening it and then handle the error.

i am looking for a way to insert a video in my software developped in C++ using the gtkmm library. But i did not see any documentation on this.
Does someone know how to put a video with the GTKmm library ?
Thanks a lot !
gtkmm itself is not a multimedia framework. However, you can use it together with multimedia frameworks, e.g. GStreamer (or gstreamermm, which is c++ wrapper for GStreamer). Here is an example of simple multimedia player written in gtkmm and gstreamermm: https://git.gnome.org/browse/gstreamermm/tree/examples/ogg_player_gtkmm

No, you cannot do that. If you want to run your app with SDL forget about DOS: DOS is not on the list of supported platforms.

I would like to get all active connections (similar to TCPView from sysinternals) on a windows machine, using WinAPI.
How can I do this using Winsock ?
Winsock does not provide any functionality to get a list of active connections.
The GetTcpTable(), GetTcpTable2(), GetTcp6Table, and GetTcp6Table2() functions of the IP Helper API provide the information that you are looking for.

How I can remotely control a GUI program using winapi?
I need to open skype or icq and click on the right contact and then read the last message. There's a program in VS spy++, but if you want to trace window messages, you need to remotely control spy++. So the problem is how can you remotely control a program and the other thing, where can you find application codes.
The White framework hides a lot of the details of UI automation, and you may find it easier to use than raw UI Automation.
