CoInitalize(NULL)
will allow you to call COM.
The #import stuff should then work.

but instead nothing is captured. i am just not sure what is needed to be specified

Depends on whether it's a command-line or GUI app. For command-line, use the standard argc/argv arguments to main().
For GUI, you can use the globals __argc and __argv that the CRT supplies, or call GetCommandLine() and parse it yourself.

Hi, I'm wondering if anyone could help me enable multiple instance on a Visual C++ program that was already made. The program disabled multiple instance so I could not run serveral of the same windows anymore, and I just want to run serveral of the same windows. For example... msn polygamy.
The program that I want to disable can be downloaded here >> http://quizquiz.nexonasia.com/download/setup.exe
It's a game that I would like to clone. I read on the site about mutliple instances and understood some of it, but I'm not good at programming languages, so I didn't know what to do.
I tried to use a hex editor to find the text string value "Mutex". But I didn't know what to change. All I know is that mutex has something to do with disabling multi instance.
I'd appreciate if someone would kindly help me out. Thanks.

Are you saying you want to modify the behavior of the binary? That can be done by patching the .exe, but don't even begin to try if you're not handy with x86 assembler and Windows internals.

I am also thinking of developing a tool for this, because there are too many apps that use the always recommended, but wrong Mutex-Trick and therefore do not behave well in an multiuser environment  . (Detailed discussion about this problem can be found in this article.)
The idea is to use one of the proposed API-Hooking techniques to catch the CreateMutex()/OpenMutex() call of the app. If the mutex to be created is the "instance mutex" we patch it's name, so it is no more unique when it should not be. To find out, which one is the "instance test mutex" you can use ProcessExplorer from SysInternals.com. Just look for Mutants in the address space of the process and if one of them seems to be the one we are searching for (often indicated by its name or an GUID as name). Then close it with ProcessExplorer and try to run another instance. If this works, you found the nasty thing.

In Internet Explorer, when we have script in a page, which calls another page and open another window. Does IE create a script engine for individual page, or just using one script engine for the Applicaiton ?

You should DL the platform SDK from here: http://www.microsoft.com/msdownload/platformsdk/setuplauncher.htm

Hi,
I did try to download the Update Platform SDK, but always the web ask me to restart the system and after that I got the message: Can not create a Server object! That is why I could not download it!
Is there other way? What I would like to do is using Visual C++ program to search the IP address the PC it is resided, do I need that SDK Platform to do this function? If not, do you know which codes I should use?
Thank you for help,
ATC

Hi,
I tried several times, any time after the site ash me to restart the computer to change the setting system ... then it said: "Can not create a Server object" ---> I could not download it!
Do you know why? By the way, what I need is using Visual C++ 6.0 codes to read my PC IP address! Do I need that SDK Platform? If not, can you show me where or how I can use codes?
Thank you for help,

Hi,
I made a DLL with a bunch of registry functions (i.e. GetProfileString, WriteProfileString, etc.) and it is performing in a way other than I expected. 
When my program uses my DLL to write to the registry, it is doing so in the folder of my program's name, not in the folder of my DLL's name.
Any ideas/solutions? Thanks in advance,

Is the following a legitimate exception throw..???
for(UINT i=0; i<m_nCount; i++){
try{
delete (myClass*)m_pStack[i];
}
catch(...){
if(m_pStack[i]!=NULL)
throw "Object doesn't exist";
}
}
Would this exception make sense to any third party using my class...???

Hockey -
The problem is that the exception handler could itself throw another exception. So, dont use the above code snippet.
For example : if m_pStack[i] referred to uncommited virtual memory, both references to m_pStack[i] would throw a ILLEGAL_ACCESS exception.

What technique should I use then...???
I think it would be wise to use exceptions when deleting memory incase it's a bogus pointer...no...???

Use the CopyFile function.

If my function has try and catch in it, do I put a return at the end of the catch block? I have a return at the end of my try block. My function returns an int.
Thanks,
ns

You should put the return outside the try catch block, otherwise you need to return inside the catch and the try. The point of the catch is that the rest of the try code will not be executed. I'd do something like this
int MyFunc()
{
int nRetVal = -1;
try
{
}
catch (...)
{
}
return nRetval;
}
Where -1 is a sensibile value to indicate failure, or to have no effect.

I've looked in my .h file quite carefully, but dont see anything suspicious:
Compile error is:
c:\trainer\db2\dbclass.cpp(4) : error C2143: syntax error : missing ';' before 'PCH creation point'
and it points to the first line in the file...
Thanks,

Probably something is wrong in your stdafx.h
Try to correct it and do a full rebuild

I had a missing ; just like it said. It was not in an obvious place, but I did track it down. Learned how importannt it is to put #include <stdafx.h> before a #import directive, the hard way!!!
Thanks for responding,
