    <p>I'm trying to determine a function's result depending on the caller's ScriptEngine:</p> <pre><code>//JScript function doSomething() { if (ScriptEngine() === "VBScript") return "this is VBScript"; else return "this is JScript"; } </code></pre> <p>But the results are:</p> <pre><code>//JScript var str = doSomething(); //"this is JScript" //VBScript Dim str : str = DoSomething() '"this is JScript" </code></pre> <p>The <code>ScriptEngine()</code> function always returns its caller's engine name, but I would like to know the <code>doSomething()</code> caller's engine name (without passing it as a parameter). Is there any way to do this in ASP?</p> <p>The motivation behind this is that I wrote a JSON utility class to use in an ASP site. The parsing of the JSON string is done via <code>eval</code> (using the validation that I found in <a href="https://stackoverflow.com/questions/2583472/regex-to-validate-json">this</a> answer).</p> <p>The result of <code>eval</code> is a JScript object (with JScript arrays and JScript dates as properties). Then the user must specify a flag to tell the function if he wants the pure JScript object or if he wants a VBScript object (with arrays and dates converted to their VBScript equivalent). I would like to eliminate that parameter.</p> <pre><code>//JScript function parseJson(jsonString, isJsObject) { var parsedObject = parsingLogic(jsonString); if (!isJsObject) //Would like to replace by engine check convertVbProperties(parsedObject); return parsedObject; } </code></pre>

    1. COYou may get better help if it was clear why this is important. Why does it matter which language the code calling the function is written in in the context of your problem?

    2. CO@AnonJr, I have added the motivation for the question. The `isJsObject` parameter is no great issue, but it would be nice to get rid of it.

    3. COThat makes sense. I don't have an answer just yet, but this will help others who might.

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
