How to get Libpng work on Visual Studio C++ Express edition

[kypho]

Hi everyone.

I have problems getting Libpng work with Visual Studio. I cannot succeed on compiling PNGTEST. It gives me this: Project : error PRJ0019: A tool returned an error code from "Testing...". I really am not sure if I have installed it right. I unpacked it to my projects folder (also zlib). I also tried to copy libpng13d.dll libpng13d.lib to my lib folder. What I have also done was that I change DLL ASM Debug to DLL Debug. I would be happy if someone there knows about this and could help me to get this properly running, but now I go to cook some Thai food

I do suggest you to use this d3dx9 function to load image. You will be able to load various image format, like: .bmp, .dds, .dib, .hdr, .jpg, .pfm, .png, .ppm, and .tga

Anyway you can post your source/project code or more info about the error message produced by VC++, I'm sure someone will help you.

It sounds like you've got the places for things a bit mixed up.  That error occurs when VS can't find all the DLLs it needs on the path.

This was all I get from the error :/ I know that this libpng is a library for handling png files in c++ and now I know that you can also use directx for that same thing. The reason why I want to use this is to use it in the "basic window setup" source code (provided in this forum), 'cos I guess it wanted to use libpng? Or can I use directx with that also?

You're passing a wrong path to command line, anyway whats is that "BAT0000012448244.bat" archive

Somehow you are missing the "" round a path, so instead of seeing

"c:\documents and settings"

as one thing, it's seeing 3 things

c:\documents
and
settings

The reason why I want to use this is to use it in the "basic window setup" source code (provided in this forum), 'cos I guess it wanted to use libpng? Or can I use directx with that also?

You can mix the two samples together (basically just add the two files together) with no problems.  In fact you need a window handle to use the directx code!

anyway whats is that "BAT0000012448244.bat" archive

I'm pretty sure it's a temp file used by msbuild.

Okay Thanks a lot guys!

I tried to add "" to paths in tools/projects and solutions but it didn't let me do that :/ I have no idea where is this path located.
So seems again that more guidance is needed. Where actually I should fix this path?

If you zip up the entire package and either post it here or PM it to me I will have a look - it's impossible to tell exactly what's wrong with the information you've posted.
