Thread: Some reg editing help please...

Ok first off. I know what your going to say, "You should learn this and this before you do that". I know I should but I want to skip the stuff I won't use right now and get on to something I will use. I amtrying to make a preogram delete a certain key. Now I heard of this website that tells the functions for it all, but I'm not sure if I am doing any of it right. Well just look at the start of the code...

Code:

#include <iostream.h>
#include <conio.h>
#include <cstdlib>
int main()
{
    LONG RegConnectRegistry(mycomputername,HKEY_CURRENT_USER,PHKEY phkResult);
    LONG RegDeleteKey(HKEY_CURRENT_USER,Test Key);
    getch();
    return 0;
}

Yes I did put extra #include files in it because I will use them later. But it says there is a syntaxt error before the ( in the the LONG RegConnectRegistry line.

There is also this error I had before and is relly bugging me...
` LONG' undeclared (first use this function)

Soo.... say anything you want but I would perfer just a little help please...

Thank you.

Edit: I think I may have put this post in the wrong forum. Oops...

Edit Edit: And yes I know I need more functions to make this work but first I need to know what is wrong here.

>>I know what your going to say, "You should learn this and this before you do that".<<

And you would be completely correct.

>> I want to skip the stuff I won't use right now<<

Like the fundamentals.

The reason that people recommend you learn fundamentals and have a minimum understanding of them is so they don't have to be confronted with a sequence of predictably tiresome questions, the answers to which the questioner could have almost certainly worked out for themselves if they had shown a mote of wisdom by not attempting to "skip stuff" they imagined they didn't need but most certainly did.[/"say anything you want"]

LONG is a windows data type - #include <windows.h> is more or less mandatory for windows programming.

Code:

LONG RegConnectRegistry(mycomputername, HKEY_CURRENT_USER, PHKEY phkResult);
LONG RegDeleteKey(HKEY_CURRENT_USER,Test Key);

These are some kind of evil hybrid of function declarations and attempts to make function calls - the preceding LONG is the return type and should only be given if declaring a function. PHKEY, too, is a data type (pointer to an HKEY) and shouldn't be used in this context unless you're attempting a type cast. Where are phkResult, mycomputername etc declared and defined? Don't use <iostream.h> use <iostream> instead....

If you insist on stumbling blindly around winapi registry functions, very possibly to the detriment of someone's operating system, then this is the msdn start page for the winapi registry.

If, however, you choose a wiser course then try to learn a little of the fundamentals of windows programming first; theForger's Win32 API Tutorial is very popular and a search of these boards and with google will turn up countless sources.
