In QGIS 1.9.0 Alpha, ECW is not shown as supported Raster Format.
Gdalinfo reports, that NCSEcw4_RO.dll and other dlls are missing.
I installed sdk4.2 from ERDAS.
After restart, gdalinfo reports:
Can not load requested DLL: C:\\OSGeo4W\\\\bin\\gdalplugins\\1.9\\gdal_ECW_JP2ECW.dll
193: %1 ist keine zulässige Win32-Anwendung

The ECW plugin in OSGeo4W is marked as obsolete. For now ECW is unsupported in OSGeo4W - the licensing is unclear.

first i copied the sdk vc 10 win32 dll in the gdalplugin, 1,9 directory and the system32 folder in windows. This was the solution in the gdal 1.9.0 version.
Now i copied the dlls directly in the bin path: "C:\\OSGeo4W\\bin" and ecw is supported now in gdal 1.9.2 (see attached jpg)
It is good to have ecw support, because the format is often used.

This is not an QGIS issue - if GDAL has ECW support, QGIS will use it. But GDAL in OSGeo4W currently doesn't have ECW support (the old plugin might even break the newer GDAL - so it was marked obsolete there).
