• Optional parameters with PHP SoapClient class on wsdl mode

  - by Maraino

  With the SoapClient class on PHP5.x and working against a SOAP web service that has optional parameters in its methods, you won't have any problem if you use the non-wsdl mode. But, at least by default, with the wsdl mode, if you don't fill all the parameters you will get an error like: SOAP-ERROR: Encoding: object hasn't 'xxx' property Is there any way to avoid that error without working with the non-wsdl mode and without filling all the parameters?

• UDK: Error, Unrecognized member 'OpenMenu' in class 'GameUISceneClient'

  - by Ricket

  Upon compiling, I am getting the following error: C:\UDK\UDK-2010-03\Development\Src\FixIt\Classes\ZInteraction.uc(41) : Error, Unrecognized member 'OpenMenu' in class 'GameUISceneClient' Line 41 is the following: GetSceneClient().OpenMenu("ZInterface.ZNLGWindow"); But when I search for OpenMenu, I find that it is indeed defined in GameUISceneClient.uc of the UDK: Line 1507: exec function OpenMenu( string MenuPath, optional int PlayerIndex=INDEX_NONE ) It looks like I have everything correct. So what's wrong? Why can't it find the OpenMenu function?

  - by wuntee

  I am trying to figure out what is the best way to go about creating dialogs. I can either create my own Dialog class (which, to me, is more clean and organized), or I can use AlertDialog.Builder (which would be done inline, and funky looking)... What are the positivies and negatives of either implementation? The only thing I can think of is application size...

• Opposite method of math power adding numbers

  - by adopilot

  I have method for converting array of Booleans to integer. It looks like this class Program { public static int GivMeInt(bool[] outputs) { int data = 0; for (int i = 0; i < 8; i++) { data += ((outputs[i] == true) ? Convert.ToInt32(Math.Pow(2, i)) : 0); } return data; } static void Main(string[] args) { bool[] outputs = new bool[8]; outputs[0] = false; outputs[1] = true; outputs[2] = false; outputs[3] = true; outputs[4] = false; outputs[5] = false; outputs[6] = false; outputs[7] = false; int data = GivMeInt(outputs); Console.WriteLine(data); Console.ReadKey(); } } Now I want to make opposite method returning array of Booleans values As I am short with knowledge of .NET and C# until now I have only my mind hardcoding of switch statement or if conditions for every possible int value. public static bool[] GiveMeBool(int data) { bool[] outputs = new bool[8]; if (data == 0) { outputs[0] = false; outputs[1] = false; outputs[2] = false; outputs[3] = false; outputs[4] = false; outputs[5] = false; outputs[6] = false; outputs[7] = false; } //After thousand lines of coed if (data == 255) { outputs[0] = true; outputs[1] = true; outputs[2] = true; outputs[3] = true; outputs[4] = true; outputs[5] = true; outputs[6] = true; outputs[7] = true; } return outputs; } I know that there must be easier way.
