How can I make a indicator transparent grey?

Picture control support 1 bit transparent, not 1 byte alpha channel (for translucent).  Just like those old vector image types: wmf, emf, it is limited by the image file format (picture ctrl is a mix of raster image and vector image).

However, it's background, like all other controls support translucent.

Interesting, i'll have to test that when i get home.

The emf standard does support gradients and alpha blending:

EMR_ALPHABLEND: This record specifies a block transfer of pixels from a source bitmap to a destination rectangle, including alpha transparency data, according to a specified blending operation.

EMR_TRANSPARENTBLT: This record specifies a block transfer of pixels from a source bitmap to a destination rectangle, treating a specified color as transparent, stretching or compressing the output to fit the dimensions of the destination, if necessary.<18> 

It's just that LV didn't catch up.

Classic controls to the rescue!
