error loading libpng

This is a strange problem... libpng fails to load upon opening foobar, it seems quite randomly. Most of the time, it loads fine, however every once in a while it fails to load and the default foobar buttons are displayed. Any ideas on how to stop this? I have the latest libpng13.dll and zlib1.dll in my components folder...

Exactly the same situation is here! -> Columns UI (newest version)

I believe it's a bad image file for your buttons.

These two files should be placed in foobar's main directory, not in components directory. Remove these files from components directory if they are there...

Sorry, I don't really know of any specific reason for this (I don't have this issue though).

That error message is outputed if the call to [a href="http://msdn.microsoft.com/library/default.asp?url=/library/en-us/dllproc/base/loadlibrary.asp]LoadLibrary[/url] fails. If it truely is random, you can try repeatedly pressing the "info" button in columns prefs under the other tab, which will report the exact error when it fails to load libpng. However, it is probably likely it is some factor only present during fb2k startup causing it. Just speculating, but are you running from a limited account maybe? How many components do you have? And how often is "once in a while"? You could try putting them in your main foobar folder instead of the components folder if that is where you put them.

In any case, you can switch to using bmps instead as a workaround. If you need transparency and are using XP, a simple way to convert the 32-bit png to a 32-bit bmp is using MS Paint - open the png in paint, save it as a "24 bit bitmap", which actually then saved it as a 32-bit bmp last time i tried anyway.

I think that did the trick... so far working fine. Thanks all.

I'm also having the same problem... just compiled pnglib 1.2.8 with zlib 1.2.2 and put both of them in foobar2000's main dir.

Using Columns UI 0.1.2 gives me this failure upon startup:

I'm also having the same problem... just compiled pnglib 1.2.8 with zlib 1.2.2 and put both of them in foobar2000's main dir.

Using Columns UI 0.1.2 gives me this failure upon startup:

Known bug, sorry for the time being you will have to use the official binaries or anything linked with msvcrt.dll, or use bitmap files instead. (I was passing a FILE handle to libpng without thinking, furture version will use foobar's reader service instead.)

PS use [codebox ] [/codebox ]for crashlogs
