Thanks i am using ver 10 as well, i used this it worked without the " ", i just wrote con(isnull(myraster.tif),0,myraster.tif) and it worked one time and that was it, it stoped again, is there any syntax error in my used format?

The quotes are required if you are using the Raster Calculator tool. The text inside the quotes must either be the path to a raster (or simply its name if the raster is in the current workspace) or the name of a raster layer in ArcMap.

Did it say something like "myraster.tif does not exist or cannot be found"? I'm not sure why but after one or two times, I have to restart Arc to get it to do more.

Try this:Con(IsNull("myraster"),0,"myraster")

This works in the Raster Calculator, for v10, with ESRI GRIDs. Not sure if it's the same for v9.3, or for other formats.
