Thanks Blake Miller: CreateProcess and process groups (2)

Hello everybody!

First of all, thanks for your answer Blake Miller!!!

I didn´t explain the situation correctly.
I mixed up with the example!!
Sigh | :sigh:

I´ll try to explain it correctly...

I´m using CreateProcess to create a new process, with the
CREATE_NEW_PROCESS_GROUP flag set in the argument "dwCreationFlags",
to create a new process group.

Let´s suppose that PROCESS_A creates a new process,
with CREATE_NEW_PROCESS_GROUP flag set. This new created
process (PROCESS_B) is the 1º process of the process group.

It´s true that both the 1º process of a process group and
the process group itself have the same ID. So the ID of
the process group and the PID of PROCESS_B are the same.

If the PROCESS_B creates a new process (PROCESS_C) with
CREATE_NEW_PROCESS_GROUP flag cleared, both PROCESS_B
and PROCESS_C will belong to the same group.

PROCESS_B knows the ID of its process group, as it´s
its own PID. But...

-How can PROCESS_C get the process group ID?
(without using IPC or passing it through command line
arguments)

-Is there any function which returns the process group ID
of the calling process?

Summing up...
I only what to know how to get the ID of the process
group, to which a process belongs.

Thanks and bye.

Hi,
You may use ASPI or SPTI to read CD sector.
Scan TOC to locate specific folder descriptor ( see ISO 9660 ).
To send ASPI command you may use "SendASPI32Command" function from winaspi.dll, or use DeviceIOControl to send SPTI command.

Slava.

It would be helpful if you could determine if none of the fonts work, or just the UrduPhonetic font. That would go a long way in isolating the problem to the code or the font. Is this a proprietary font, or one that can be freely downloaded?

Revision Control System and Tools

Hello all,

although this question is not related to the forum's specifics, I'd like to ask it here because I hope to get some answers from users of a Revision Control System.

I need to switch from Visual Source Safe to a Revision Control System which allows me to:
1. access projects over the Internet
2. have tools to integrate Visual Studio 6 and Visual Studio .NET
3. have additional tools to allow me to maintain todo's / work progress and to create version-based reports of my team's work

For the first two needs, after a quick search, I've found that a Subversion server with it's plug'ins might do the job.

So, my questions are:

- is Subversion good enough or are there better alternatives?
- which SCC provider should I choose: Subway, SourceCross or AnkhSVN? AnkhSVN is only for Visual Studio .NET, so if I choose it I'll also need one of the first two for Visual Studio 6.
- are there any Visual Studio-integrated tools which work with Subversion to help me maintain the list of todo's / work progress and any external tools to allow me to crete version-based reports (something like:
v1.0
Bug #1 - Bug description - Status: Fixed
New Feature #1 - Feature description
etc.

Thanks.

George Ionescu

Hi , I'm working with eMbedded Visual tool3 V3 .......
I want to use Shellexec func. .....
I tried it on visual studio 6 and it worked correctly without any problems or (including any additional files) , but in the eMbedded c++ , in the compiling , it says (UNDECLARED IDENTIFIER) although the autoComplete (ctrl + space ) gets me the function...
(is it required to include any header files ex: shellapi.h or refere to any dll ex: shell32.dll as MSDN says , I included the file but couldn't make anything with the dll)
The same is for WinExec func.

I have a dll file written in eVC++ 3.00 for PocketPC.
It is an api for a Hp PhotoSmart Built-In Camera. My task is to utilize this dll via Vb.NetCF.

There is a function in the dll called:
hpCamOpen()

This function is suppose to return a handle that is used to open the camera up to the other functions in the dll.

Here is some of the code from the source of the dll.

typedef HANDLE (*HPCAMOPEN)();
HPCAMOPEN HpCamOpen;

What I want to know is what does the "HANDLE" represent and what data type is it?

Thanks in advance.
