First, you can't retrieve/use a key value after you delete it. You delete it when you are done.

Second, if you have a file gaben.txt

"gaben"
{
    "firstkey"
    {
        "food" "donuts"
    }

    "secondkey"
    {
        "food" "fried chicken"
    }
}

and you want food is associated with the firstkey, this will print it:

CON_COMMAND(kv_test, "test keyvalues")
{
    // open KeyValues file
    KeyValues *MainKV = new KeyValues("gaben");
    bool found = MainKV->LoadFromFile(gFileSystem, "addons/myplugin/gaben.txt");
    if (!found)
    {
        MainKV->deleteThis();
        META_CONPRINTF("error opening MainKV\n");
        return;
    }

    // find sub key
    KeyValues *SubKV = MainKV->FindKey("firstkey");
    if (SubKV)
    {
        META_CONPRINTF("food for firstkey is '%s'\n", SubKV->GetString("food"));
        SubKV->deleteThis();
    }
    else
    {
        META_CONPRINTF("could not find SubKV\n");
    }
    
    MainKV->deleteThis();
}

Console should look like this when you type 'kv_test':

kv_test
food for firstkey is 'donuts'

No file will say "error opening MainKV" and if "firstkey" is not found it will say "could not find SubKV".

yep duke i understood that in our chat, but what happens if it dosent exist how is it created

Never tried it, but I assume you would do

KeyValues *pMyNewSubKey = new KeyValues("mysubkey");
pMyNewSubKey->SetString("food", "mmmm...beer");
MainKV->AddSubKey(pMyNewSubKey);

I would suggest searching the SDK code to see how Valve does it. It looks like they use AddSubKey in cl_smoke_trail.cpp, FileOpenDialog.cpp, InputDialog.cpp, ListPanel.cpp, etc.
