 |

Pretty much what the subject line says - is there a way to retrieve the file size of a file you open with openFileAsProcess() ?
I scanned the celua file but didn't find anything that seems to do that.

| Code: | function fsize (file)
local current = file:seek()
local size = file:seek("end")
file:seek("set", current)
return size
end
function OpenFile()
dialog = createOpenDialog(self)
dialog.Title = "Select File"
dialog.InitalDir = os.getenv('%USERPROFILE%')
dialog.DefaultExt=".exe"
dialog.Options ='[ofEnableSizing]'
if dialog.execute() == false then return end
FileName= dialog.FileName
file = io.open(FileName,"r")
print(fsize(file)..' bytes')
file:close()
dialog.destroy()
openFileAsProcess(FileName,false)
print('test a')
version = AOBScan("00")
if (version ~= nil) then
print('test b ')
end
end
OpenFile() |

| Code: |
local modules = enumModules(process);
local mainModule = modules[1];
local size = getModuleSize(mainModule.Name);
print(size);
|
Has no error checking, so would suggest adding checks for valid returns. This will ask for the current selected process module list, then use the first (main module) to obtain the size of. (The first entry in the module list should always be the process that owns the module list being requested.)

@atom0s, is that using enumModules return the memory usage by opened process, not the file size?

To get on-disk size, you can use:
| Code: |
local modules = enumModules(process);
local mainModule = modules[1];
local f = io.open(mainModule.PathToFile, 'rb');
local size = f:seek('end');
f:close();
print(size);
