how tp Open bitmap in photoshop from coreldraw x6(x64)?

The edit bitmap button in CorelDraw creates a CPT file intended for photopaint. As far as I'm aware, photoshop cannot open CPT files. Therefore, it is unlikely that you would be able to use photoshop with the edit bitmap button.

But because CorelDraw can create files in any of the formats that Mike has listed, maybe if you search macromonster, gdg macros and similar sites you will find a macro that does the job. But note that the Home and Student version of CorelDraw does not have the VBA licence required to run CorelDraw and also check if your macro is available for X6.
