i do not use mbm file, i read the file directly and just put bmp files in that directory.
_LIT(KMBMFILE, "\\system\\picture\\smiley.bmp");
TFileName file(KMBMFILE);
iMyDecoder->StartDecodeAndDisplay(file);

Hi System error -12 means KErrPathNotFound (Unable to find the specified folder ) .

what about wserv 9?

tired!

WSERV 9

Attempted to use a non-active graphics context.

A drawing request was sent to a graphics context when the context was not active.

On the server side, this panic is raised by CWsGc::CommandL() on all requests received when the context isn’t active except EWsGcOpActivate, EWsGcOpDeactivate, EWsGcOpFree, and EWsGcOpTestInvariant.

TFileName file(KMBMFILE);
iMyDecoder->StartDecodeAndDisplay(file);

Your path is not completed, no driver letter.

thanks! it can display the picture

iDrawBltAppView->DrawMyBitmap(iBitmap);
the DrawMyBitmap(...) function is error
