Hello everyone!
I need some help about this main problem;well I created one PDF document which is going to be the help of my application.Now I want to "link" this help to the program itself.In other terms, I want that the application calls the pdf reader to open the pdf file when the user click on the menu help button.
I wanted to know how do I do that.Thanks for your attention and answers.

I do such things in this way:

Code: (C)
1	g_spawn_command_line_async("xdg-open my_help.pdf", NULL); // my_help.pdf - your file

Thanks.But when I try it my program crash.I'm on windows.I have of course made some search about. But I'm a bit lost.Especially with the function "g_spawn_async ()".Could you help me again? or at least give me an example of code?

My code snippet looks so:

Code: (C)
1 2 3 4 5 6	#if defined WIN32 ShellExecute(NULL, NULL, "my_file.pdf", NULL, NULL, SW_NORMAL); #else g_spawn_command_line_async("xdg-open my_file.pdf", NULL); #endif

Unfortunally there is no common way for Linux and Windows. This code snippet works in my program on Linux and on Windows any way.
