CDS_FULLSCREEN

Recommended Posts

I get an error for the following code: _________________________________________________________________ if(ChangeDisplaySettings(&dmScreenSettings, CDS_FULLSCREEN)!= DISP_CHAN_SUCCESSFUL) { //Setting display mode failed. MessageBox(NULL, "Display mode failed!", NULL, MB_OK); fullscreen=FALSE; } //End of if(). _________________________________________________________________ it says that CDS_FULLSCREEN is undeclared! i am so confused. i can''t even get my FIRST application to run! somebody please help.

You need to upgrade your MinGW32 headers, since you''re using very old headers that had CDS_FULLSCREEN missing. The headers can be found at mingw.sourceforge.net. Or, if you just want to halfway fix the problem, listen to Monder (although I''d brace it in a check to make sure CDS_FULLSCREEN isn''t already defined).

I''m assuming you''re using dev-c++ here cause you seem confused by the command line.

Go to something like project->linker options(it''s something like that) and in the extra libarys textbox put -lopengl32 -lglu32 oh and make sure you started a windows project. If you aren''t using dev-c++ post back with the compiler you are using

In Dev-C++ you can go to the project options (I think you can press alt+p to get there) and there is a text box somewhere for you to add options for when it calls the linker. The -l switch tells it you want to link to a library, and you follow it with it''s name, so you will put -lopengl32 and -lglu32 in that box.

While you''re there, you might want to add -Wall to the compiler options. (it''s case sensitive!) This will cause the compiler to tell you when you do stupid things, like statements that do nothing, writing if(a=4), declaring variables and not using them, not initializing variables, and other odd things like that that tend to make people scream.

just put

#define CDS_FULLSCREEN 4

at the top of your code and everything should work fine


You should probably use

#ifndef CDS_FULLSCREEN
#define CDS_FULLSCREEN 4
#endif

so it works for people who don''t have buggy headers.

ok nevermind...i think i figured it out. i guess i gotta get new libraries and headers. does anybody know where to get the latest mingw headers and libraries, along with the newest opengl ones?
