get the filesize of a running .exe

[shizzl]

Hi,

i try to get the filesize of running .exe applications for a Taskmanager App.

When i execute:
User::LeaveIfError(fs.Entry(KFilePath, entry));
TInt fileSize = entry.iSize;

i get a "unable to execute file for security reasons" error.
I guess this error is because the exe is running. Or is it because the files is in /sys/bin/ ??

I have no AllFiles capability.


then i tried wiki example to get filesize with RFile

_LIT(KFileSpec,"C:\\Test.txt");
RFs fs;
User::LeaveIfError(fs.Connect());
CleanupClosePushL(fs);

RFile file;
TInt Err1=file.Open(fs,KFileSpec,EFileRead);
if(Err1==KErrNone)
{
TInt Size;
file.Size(Size);
HBufC8* buffer = HBufC8::NewLC(Size);
TPtr8 ptr= buffer->Des();
file.Read(ptr);
file.Close();
CleanupStack::PopAndDestroy(buffer);
}
fs.Close();
CleanupStack::PopAndDestroy(&fs); // destroy fs

I dont understand the example?
where can i define my TInt filesize = ... ??

would be nice if someone could help here.

Basically the executable is inside protected folders, thus if you would want to get the filesize for them you would need to have AllFiles capability.

really? i thought i only need AllFiles for write, but not for read...

Basically you need AllFiles for reading, and for writing you actually would need to have TCB.

All and all, those capabilities are really hard to get, thus would suggest you to re-think the requirement. And maybe you can do the task you are thinking you need these some other way, thus can you explain what is the use case you are trying to achieve ?

i want to create a taskmanager app. The taskmanager should display size of running programms...
So i guess i will have a round at the test house..

@pavarang, thanks for the link, now it is clear. AllFiles is needed to read data in /sys/

Basically it would not make too much difference on showing teh filesize, so I would really consider dropping it out. Getting teh capability is not an easy task.

Hello,
as Symbianyucca already said, file size isn't such a foundamental info....
but now you are talking about size of running programs, so maybe you are referring to memory occupation?
If so, RProcess::GetMemoryInfo could be a better solution:

There's an old task manager project, unfortunately for 2nd ed devices, but i think you can grab some nice ideas on how GetMemoryInfo works:
