You need to declare an instance of class GoGoGo before this will work - i.e.:
GoGoGo executesBeforeMain;

It has to be

class GoGoGo<br />
{<br />
public:<br />
GoGoGo()<br />
{<br />
cout << "This runs first!";<br />
//put ur code to crash the program here..<br />
}<br />
}BeFirst;

int CrashingFunc();<br />
<br />
static int SomeIntThatCrashesTheProg = CrashingFunc();<br />
<br />
int CrashingFunc()<br />
{<br />
    // Put crashing code here<br />
}

The static variables will be evaluated first and this will call your CrashingFunc before the main()

is it neccesary to put static .

static int SomeIntThatCrashesTheProg = CrashingFunc();<br />
<br />
int CrashingFunc()<br />

I feel int SomeIntThatCrashesTheProg has to be Global which u have defined with static

If so, you will do a never ending study. Atleast after you start with windows programming. (If you ever finish studying this with C and C++) Big Grin | :-D

Why do this dude? Destructive mind huh? Dead | X|

Is it possible to use extern for Objects also. I know we can use it for variables but not sure for object.

Also what I want mainly is I don't want to create new objects I just want to use that same object in it's present state.

And last but not the least, Thankx a lot for answering my question and taking time for it.

Regards

Mahesh

Hi All,

I am faced with a situation where a window from my application needs to handle events the notifications for which are going to another window.

Can someone tell me how I can make my window get the event notification?

More specifically, the issue is regarding the Drag and Drop implementation between my namespace extension and windows explorer. I need my namespace extension to get a notification that a file has been dragged from here and dropped on a particular "Windows Folder".

Thanks in advance,

Regards,
Anil

Dear Sunit5,

My First Target is to custamize the exiting GINA statically. Some one suggested that you can directly modify the existing dialogs by opening it in VC++ Stdio. But I am not able to open the GINA Dialogs in VC++ stdio.
Please let me know How I can achieve it.

2nd Target is to modify GINA dynamically or using another GINA DLL which may be I can achieve by writting GINA DLL as described in "Building and Testing a GINA DLL" in MSDN.

I am using Windows XP.

Thanks and Regards
Manoj

Technically, yes. That is, in a hosted iexplore AciveX. This code can even interact with your C++ code by calling its functions (and vice versa).
Search MSDN for something like "custom menu explorer" (without quotes).

Use Ctrl+Left/Right to switch messages, Ctrl+Up/Down to switch threads, Ctrl+Shift+Left/Right to switch pages.
