If you use const int constants instead of an enum, you don't need.

That's true. But I've managed to simplify this function while still using an
enum.

+    int in_value,
+    ProxyPrefs::ProxyServerMode* out_value) {
+  DCHECK(out_value);
+  if (in_value == ProxyPrefs::DISABLED) {
+    *out_value = ProxyPrefs::DISABLED;
+    return true;
+  } else if (in_value == ProxyPrefs::SYSTEM) {
+    *out_value = ProxyPrefs::SYSTEM;
+    return true;
+  } else if (in_value == ProxyPrefs::AUTO_DETECT) {
+    *out_value = ProxyPrefs::AUTO_DETECT;
+    return true;
+  } else if (in_value == ProxyPrefs::MANUAL) {
+    *out_value = ProxyPrefs::MANUAL;
+    return true;
+  } else {
+    return false;
+  }
+}

+bool ProxyPrefs::StringToMode(

Do this with a small table?

[gfeher, 2010/12/16 23:54:29]

Done.

+    *out_value = ProxyPrefs::DISABLED;
+    return true;

+    return true;

+    return true;
+  } else if (in_value == "manual") {
+    *out_value = ProxyPrefs::MANUAL;
+    return true;
+  } else {
+    return false;
+  }
+}
