CLSID blank in W10 machine per _GDIPlus_EncodersGetCLSID ... Ideas?

Recommended Posts

Posted (edited)

Hope this is simple.

While troubleshooting inability to save an image to file with _GDIPlus_ImageSaveToFile on a W10 machine...

Discovered that the CLSID comes up as an empty string per _GDIPlus_EncodersGetCLSID("jpg")

  • My W7 machine returns a normal CLSID and saves jpgs fine. 
  • This W10 machine (1803 / 64 bit) will save a jpg in "Paint" and "Paint3D", but not with GDIPlus.
  • Doesn't show as having encoders for "bmp" or "tif" either.
  • My web searching hasn't yielded results...

What to do about no apparent (or accessible) encoders?

Thanks for your time and input.

Ed

#include <GDIPlus.au3>
;W10 machine in question returns a blank string for each.  W7 returns the same string ~36 char clsid for each
_GDIPlus_Startup()
ConsoleWrite('_GDIPlus_EncodersGetCLSID("jpg") =  ' & _GDIPlus_EncodersGetCLSID("jpg") & @CRLF)
ConsoleWrite('_GDIPlus_EncodersGetCLSID("jpeg") = ' & _GDIPlus_EncodersGetCLSID("jpeg") & @CRLF)
ConsoleWrite('_GDIPlus_EncodersGetCLSID("bmp") =  ' & _GDIPlus_EncodersGetCLSID("bmp") & @CRLF)
ConsoleWrite('_GDIPlus_EncodersGetCLSID("tif") =  ' & _GDIPlus_EncodersGetCLSID("tif") & @CRLF)
ConsoleWrite('_GDIPlus_EncodersGetCLSID("png") =  ' & _GDIPlus_EncodersGetCLSID("png") & @CRLF)
_GDIPlus_Shutdown()

Win 10 Ver 1809 / 64 bit, I get:

_GDIPlus_EncodersGetCLSID("jpg") =  {557CF401-1A04-11D3-9A73-0000F81EF32E}
_GDIPlus_EncodersGetCLSID("jpeg") = {557CF401-1A04-11D3-9A73-0000F81EF32E}
_GDIPlus_EncodersGetCLSID("bmp") =  {557CF400-1A04-11D3-9A73-0000F81EF32E}
_GDIPlus_EncodersGetCLSID("tif") =  {557CF405-1A04-11D3-9A73-0000F81EF32E}

Thank you for the grabs.

These are identical to other machines that I've also checked today.   Same CLSID between all machines, W7 & W10.

So, not specifically an AutoIt question...what to do when your machine doesn't have encoders showing?

Follow up for anyone else dealing with similar problems:

Seems to have been the result of an issue that appeared in AutoIt version 3.3.14.3, and is now corrected in at least 3.3.14.5

When I compiled and/or ran under 3.3.14.2 I got a handle of 'true' and complete CLSID results.

When I compiled and/or ran under 3.3.14.3 I got a handle of 'true' but no CLSID results.

...with all other variables equal.  Tried on 5 machines (compiled version).

Then uninstalled 3.3.14.3 (not working) from one of the machines, installed 3.3.14.5, and it returned the values successfully.
