Thread: why doesn't the registry work?

why is it, that I can save some registry info and it works in XP, but when i run the same program on 98, it doesn't do anything?

here is my code:

Code:

//include stuff

void writetoKey(HKEY keypath, char *keyname, unsigned int type, char *value)
{
	unsigned long result;
	HKEY key;

	RegCreateKeyEx(
		keypath,
		keyname,
		0,
		NULL,
		REG_OPTION_NON_VOLATILE,
		KEY_SET_VALUE,
		NULL,
		&key,
		&result
		);

	switch(result)
	{
	case REG_CREATED_NEW_KEY:
		cout << "Created new key" << endl;
		break;
	case REG_OPENED_EXISTING_KEY:
		cout << "Key already existed, rewriting" << endl;
	}

	RegSetValueEx(
		key,
		NULL,
		0,
		type,
		(LPBYTE)value,
		strlen(value)+1
		);

	RegFlushKey(key);
	
	RegCloseKey(key);
}

int main()
{
	char fullpath[]="C:\testfolder\EXE\OpenScript.exe %1";
	char tempname[]="ost_auto_file";

	char tempname2[]="%SystemRoot%\\system32\\NOTEPAD.EXE %1";

	writetoKey(HKEY_CLASSES_ROOT,".ost",REG_SZ,tempname);
	writetoKey(HKEY_CLASSES_ROOT,"ost_auto_file\\shell\\edit\\command\\",REG_EXPAND_SZ,tempname2);
	writetoKey(HKEY_CLASSES_ROOT,"ost_auto_file\\shell\\open\\command\\",REG_EXPAND_SZ,fullpath);
	return 1;
}

any help would be greatly appreciated. I need to know if there is a way to edit the registry on ALL (or most) operating systems...

-thanks in advance

ok, lmao, it turns out, it was elsewhere in my code

in my installer, i have to call my wrap program (wrap.exe) and it returns a value as to whether or not an error occured, so i did something like so:
if(!system("wrap.exe Installdata.wrap C:\testfolder"))
return 0;

in other words, it's kinda like a function, but actually running another exe....

now, i noticed that i tried to output stuff after i had unwrapped everything, and it wouldn't output anything in 98....so what i'm guessing is that windows doesn't support jumping back IN to the calling program, and that it just stops after the called one is done.....

i don't know, i'm just assuming that, maybe someone else can give some light to this situation?
