i have an options dialog that starts up before the actual program starts. the option dialog has a details dialog that shows information such as GL_VENDOR, GL_RENDERER, etc. however, when i try to get the requested information, it cannot be found.
if i have a dummy dialog that performs the exact same thing with the exception that it is invoked after the program starts, it can find the relevant information.
my question is: do you have to create a working window with opengl already running to get this information, or can you just call glGetString regardless if opengl is set up or not?
