seriously?

go to Project / Settings / C|C++ . do you you have anything in the "Preprocessor definitions" field?

what preprocessor symbols are you defining when you build zlib, and which are you defining when you build your project?

you can't delete anything from the external dependencies folder. that folder is just to show you the files that have been included based on your #include statements and the include paths you've defined.

can you show me the link that you downloaded?

the zlib calls are inflate, inflateInit, inflateEnd.

if commenting those out eliminates the crash, then the problem is probably that the zlib functions are not being exported from the DLL with the calling convention that your application expects.

what did you do to get zlib to compile as a DLL?

can you try commenting-out just the calls to zlib ?

did you build the copy of zlib.dll that you are using?

are you using any other (non-MS) external libraries ? (statically linked)

when you #include "zlib.h", are you doing this:


#ifdef __cplusplus
extern "C" {
#endif
#include "zlib.h"
#ifdef __cplusplus
}
#endif


?

i'm assuming you're using pngLib to create your PNG file. so, you would do the png_write_chunk wherever you are doing all the other libPng stuff.

how are you #including the zLib header?

you can use a tool like pngsplit to insert a custom chunk into an existing image. to add a new chunk to an image while you're writing it, use png_write_chunk (after png_write_info, IIRC).

"Module" is not an English verb. You can't "module" anything.

you can modulate a number: x = x % 1007;
