I noticed that
form.icon()
did not work properly under MinGW - long story short, turns out that the WideCharToMultiByte call got an incorrectcbMultiByte
parameter - thus returned anERROR_INSUFFICIENT_BUFFER
error.mbstr.resize(bytes - 1);
is correct - that is counted without the terminating zero.cbMultiByte
, however is "Size, in bytes, of the buffer indicated by lpMultiByteStr." so the terminating zero must be counted too.I am not sure how to proceed with adding checks for all return values of all of the
Stringapiset.h
calls here, so I'll leave that for later. Ideallywc2mb
should have failed though.
