Is it easier to create INI file in REGISTRY
then READ/WRITE TO it?

For your kind of application, the registry shouldn't be used.

Well, you actually can, but you definitely shouldn't.
The registry should be used for maintainig application settings (i.e. few data), not as application general data storage (i.e. big amount of data).

Reading and writing to a INI file it is very simple.
You can easily make a 'test' INI file, using, for instance the notepad, and then write to (or read from) programmatically.
Check out one of the articles I linked in one of my previous replies to see (in the source files) some sample code.

but it all tells abt WIN32 CONSOLE Application...

whereas i need.... MFC Application

For the purpose of read/write to a INI file, the fact it is negligible.

BTW are you able to code a very simple MFC application?

Then shouldn't be difficult for you to have a look at the (console) article and adapt the code to the MFC application. Good luck.

I went through all the codes and sites....
BUt its all WIN32 CONSOLE application...

what i want is MFC Application...

The other programs i got is
MFC Application.........but...
It just reads an INI file...thats already created...

Im using Visual Studio 2003.....
Visual Studio 2008 supports CIniFile....
but the lower versions dont....

so is there any direct....or easy way to READ/WRITE INI file...
Other than using the CIniFile code availabe in this forum????

You must redirect the CWinApp application data storage from the registry to your ini file. See the MSDN documentation on CWinApp::m_pszRegistryKey and CWinApp::m_pszProfileName.

By freeing m_pszRegistryKey and setting m_pszProfileName to an appropiate path you will be able to use CWinApp::GetProfileString
CWinApp::GetProfileInt
CWinApp::WriteProfileInt
CWinApp::WriteProfileString
on an ini file instead of the registry.

When I switched my application to use an .ini file, this took me a while to find out. However, it's not likely we are the first people to face this issue ... there must be an example somewhere. Unsure | :~

Hi all,

I am checking this condition in VC2008

if((fp!= NULL) && (fp.m_hFile != 0xFFFFFFFF))

but its giving an error:-

error C2040: '!=' : 'HANDLE' differs in levels of indirection from 'unsigned int'

How can i remove this error?

Thanks in advance

You need a cast to HANDLE, ((HANDLE)0xFFFFFFFF)

BTW, there is already a definition for this, #define INVALID_HANDLE_VALUE ((HANDLE)(LONG_PTR)-1)
use INVALID_HANDLE_VALUE.

(fp && fp->m_hFile!=INVALID_HANDLE_VALUE) maybe works?

It's easy enough to fix, as mentioned, but why are you doing a
comparison like that?

What type is fp? How can fp be compared to null then have a dot operator
used on it?

It likely belongs to CFile.

Likely?

I assumed it is CFile too, which still raises my questions - what mystery operator
is providing the OP's comparison to NULL? And if it's a CFile, why do an incorrect
and direct comparison to an internal member when the class has that stuff covered?

Get open files by process id (winapi)

Hi,

I try to build up a monitoring system, which shows me all opened files and the process ids, using this files.
All opened files mean not only the exe and dlls but .cpp , .h, .pdf, .doc, etc...
I get either the process id using a driver and "NtQuerySystemInformation" function or get the files by using "ReadDirectoryChanges".

So, how can I get the association between them? Is there a way to get it by the driver or is there any winapi function which gives me the pid and open files (not only processes and modules) together.

Thank you in advance for any hints, code or examples.

Marco
