JScript vs VBScript

Hi all I've been using TestComplete for a few years now and have been writing scripted tests in VBScript and have to say that I've never encountered any problems with doing so (at least no issu...

    Hi Stephen,



    This is interesting... I never ran into your issue because all our application (VS C++) elements that respond to wText return a String.



    With the following test code:



    function someString() {

      this.type = "someString";

    }


    someString.prototype.getString = function (){

        return new Object("aString for class " + this.type);

      }



    function TestStringVar()

    {

      var aStringObject = new someString();

      var anObject = new Object("someOtherString");

     

      Log.Message(aStringObject.getString()); 

      Log.Message(aStringObject.getString().toLowerCase()); 

      Log.Message(aStringObject.toString());

     

      // This raises the exception that triggered this thread

      //Log.Message(aStringObject.toLowerCase());

      

      Log.Message(anObject.toLowerCase()); 

      Log.Message(anObject.toString());

      Log.Message(anObject);

     

    }



    And with your code, I can reasonnably assume that if textBox.wText.toLowerCase() doesn't work, textBox.wText.toString().toLowerCase() will.



    Sincerely

Hi Simon



I think I've got it now!!



Looking back at my example, I can see that it was a poor one because the wText property does actually return a String value and works.  I just used it as an example, on the assumption (silly me!) that it would behave in the same way as another control I was working on at the time, which didn't work.



The control in question was a tab control in which I needed to obtain the text on the currently selected tab and compare it with another string.  The obtain the selected tab's text in the tab control, I am using the 'text' property, i.e. tabCtrl.selectedTab.text.  It is this that doesn't work with the toString() method unless it's created as a new String, i.e. myVar = new String(tabCtrl.selectedTab.text).  Only when I do this, can I treat it as a String object and also apply the toLowerCase() method.  It must, therefore, be held as some type other than String, so your first post was very helpful in this respect, as I wasn't aware that objects could have different types.  Your second post highlighted this in that the object you instantiated explicitly as being a String works with the code whereas the other object needs a little help.  So, putting it all together, I've been able to shorten my code a litte, it now reads as:



  myVar = new String(myObject.text).toLowerCase()



Still not as compact as the VBScript version where LCase(myObject.text) works perfectly, but still, life would be boring if we had everything!! 



Many thanks again for your time and help.



Regards

Stephen.
