I wonder if someone could give me an example of RegDeleteValue.  I know the syntax, but seeing an acutal example
would be very helpful.

Say you want to delete HKCU\key\value what would the the RegDeleteValue paramiters be?

Try something like this:
If you want to delete a value in the key you spevified then do this:

  HKEY hregkey; // Declaring a key pointer for usage.
  long res = RegOpenKeyEx(HKEY_LOCAL_MACHINE, "HKCU\\key", 0, KEY_ALL_ACCESS, &hregkey);
  if (res == 0)
  {
    RegDeleteValue(hregkey, "value") //Now let's delete the item value
  }
  RegCloseKey(hregkey);

If you want to delete the key you spevified then do this:

  RegDeleteKey(HKEY_LOCAL_MACHINE, "HKCU\\key\\Value");

Cheers,

Alan

If you want to delete a value and check if its been deleted succesfully then replace:

RegDeleteValue(hregkey, "value")

with

if (RegDeleteValue(hregkey, "value") == ERROR_SUCCESS)
{
 // Do Whatever
}

in the above code.
