When this option is enabled, only those heaps that are selected in the table will be opened for editing. If the tabs in the middle of the dialog are displaying heaps, then the last option will indicate Open Selected Heaps. If the Open Custom Range toggle is enabled, a custom memory start address and size to open can be specified in the Start and Size combo boxes. Note that if you modify a read-only portion of the file and try to save the changes, you will receive an error. Unclick the toggle to open all readable bytes. If the Open only Writeable Bytes toggle is enabled, then only the areas of the process that can be modified are opened (note that a vertical gray line just to the left of the process graph indicates which bytes will be opened). The Open Options box allows control of how the process is opened and is accessed by clicking the Options button. Which bytes are opened is determined by the toggles in the Options box. A gray vertical line just to the left of the graph indicates which bytes will be opened in the editor when the Open button is clicked. If heaps or modules are selected in the heaps or modules list, those areas will be highlighted in the graph. Areas of the process that can be modified are drawn in green, and read-only areas are drawn in gray. On the right-hand side of the display is a graph of all readable bytes of the process. Each module has a starting Address, a Size, and a Name which is usually the name of the executable or DLL associated with the module. Click the Modules tab to view a list of all modules for the current process. Each module may have a number of heaps contained within it. The Type column may be Image, Mapped, or Private.Ī module is a block of memory that is associated with an executable, DLL, or other dynamically linked library. The State column may be Free (unallocated), Committed (allocated), or Reserved (allocated but not available). The Flags indicate the access restrictions for the heap and may include Read, Write, WriteCopy, Execute, No access, or Unallocated. As well, each heap has a number of Flags, a State and a Type. Each heap has a position in memory, indicated by the Address and Size columns. A list of all heaps for the process can be viewed by clicking on the Heaps tab in the center of the dialog. A heap is simply a block of memory that has been assigned to a process. When a process is selected, a number of heaps and modules are displayed for the process in the tabbed section of the dialog. The process list can be sorted by clicking on the Process Name or Process ID headings. Each process has a name and an ID number associated with it. Note: Incorrectly editing processes can lead to programs performing incorrectly or system crashes.Ĭhoose which process to open in the Process List on the left side of the dialog. Processes can also be opened using the Command Line. To open a process, use the Open Process dialog box which can be accessed by clicking the ' File > Open Process.' menu option, or pressing Ctrl+Shift+O. The individual bytes of memory used by process can then be edited and saved back to the process. ![]()
