The Curated Books The Art of Game Design: A Book of Lenses, Second Edition, by Jesse Schell Presents 100+ sets of questions, or different lenses, for viewing a game’s design, encompassing diverse fields such as psychology, architecture, music, film, software engineering, theme park design, mathematics, anthropology, and more. Written by one of the world's top game designers, this book describes the deepest and most fundamental principles of game design, demonstrating how tactics used in board, card, and athletic games also work in video games.

A Practical Guide to Indie Game Marketing, by Joel Dreskin Marketing is an essential but too frequently overlooked or minimized component of the release plan for indie games. A Practical Guide to Indie Game Marketing provides you with the tools needed to build visibility and sell your indie games.

I can't load bitmaps!

9 posts in this topic

For some reason, I can''t load bitmaps from file into a HBITMAP handle! szfilename is a LPCTSTR string, like "testimage.bmp" Oh what is wrong?! Does it have something to do with my project''s bitmaps being in the Resource folder? (in Microsoft Visual C++) //Load the bitmap "szfilename" into the bitmap handle hbm = (HBITMAP) LoadImage(NULL, szfilename, IMAGE_BITMAP, 0, 0, LR_LOADFROMFILE | LR_DEFAULTSIZE); if(!hbm) { return 0; //error that always happens! }

You may want to explicitly specify your desired height and width, since the LR_DEFAULTSIZE flag "uses the width or height specified by the system metric values for cursors or icons." But you specified it was an IMAGE_BITMAP, not an icon or cursor.

"Does it have something to do with my project''s bitmaps being in the Resource folder?"

The bitmaps should be in the same folder as your executable. I don''t use MSVC, but I''m confident that this is the problem.

You could provide a little more information to us if you could tell us what GetLastError() is returning after the failure.

Never mind! I got my code to work by loading the bitmap from a resource script using MAKEINTRESOURCE(IDB_BITMAP) in place of szfilename.

damn, I think I got the same problem like you
my bmp file is in the debug folder, so my program should find it

how do I use that Getlasterror() code?

this is how I try to load my bitmap

  
if ((hbitmap = (HBITMAP)LoadImage(hInstance, File, IMAGE_BITMAP, 0, 0,
LR_CREATEDIBSECTION |LR_LOADFROMFILE)) == NULL)
{
Write2Log("Loading image succesfull") ;

} // end of if

else
{
Write2Log("Loading image failed!") ;

} // end of else



note that Write2Log() is a function that writes to a log-file so I knew where my program goes wrong

and second note I already used this code in an other game and there it worked fine

also note that I don't get any compile errors

thanx in advance for any help

Hey, aren''t you testing that if hbm returns NULL, it writes "Load image successful" and if it DOES return something, it writes "Load image failed". Seems to me you need to use !=NULL instead of ==NULL :

if((hbm = LoadImage(hInstance,file,IMAGE_BITMAP,
0,0,LR_LOADFROMFILE|LR_CREATEDIBSECTION))!=NULL) {
Write2Log("Load Image Successful");
} else{
Write2Log("Load Image Failed");
}

could that be my problem?
although I don't think so because the rest of my load bitmap code also fails, so I think it's not loaded well?!?
but thanx anyway, I'll check tonight, who knows

for that nice white box just use this html code
