hi,

I am trying to compile a vc6.0 project in vc8.0. I am getting the following error.

error C2061: syntax error : identifier 'THIS'

I tried to use #undef THIS and #define THIS. But it didnt work. Is it possible that old windows files are getting linked. In that case as well the definition of 'THIS' hasn't changed and its the same.

Can anyone suggest a fix?

regards,
sk80.

Shouldn't it be lower case (this)?

I wonder if there is a MACRO somewhere in your code that uses 'THIS' in place of 'this'? Search for all references to 'THIS' -- what do you get?

I can give a keyword for further searches....

MSGF_DIALOGBOX.

When a dialog comes up this is the message sent. You can trap this in WM_ENTERIDLE message handler. Check for this message inside the handler for WM_ENTERIDLE. This is in wParam argument.

If this is the case then lParam will have Handle to the dialog box or message box. Rest is up to you. He he. Big Grin | :-D

I search some messages.
They suggest to write a dialog box for it.
I use this method now!

constructor .

Nothing clever. It is trivial in C++. Everybody knows that. I want to do the same in C buddy.

ok i am sorry for that but

//global function & variables

extern int fun_Vikas()
{
return 4;
}

int io=fun_Vikas() ;

//Main fun
int main()
{
;

;
;
}

This code was compiled in vc++ compiler and
it calls the fucntion fun_Vikas before main

Cool | :cool:

Hows that
