RE: passing arrays to COM objects by ref - dll
I've been provided a .dll with a number of procedures written in VB5. The function I'm trying to access requires three inputs as arrays, the last one being an empty array (with a length) for it to store the results and return. The function requires all of the arrays by ref. I tried just passing it regular old arrays, no success. The way I've solved similar problems in the past is to do one of the following: 1. Rewrite the DLL to accept strings for all arguments. Yecch. 2. Write a COM wrapper that accepts strings, and invoke the COM DLL from within your wrapper. Also, yecch. However, this is pretty easy to do, and you can do it with Windows Script Host, so you don't even need a compiler. You would write a WSH object with a COM interface, and invoke that from CF.

Re: Passing Arrays/ResultSet between CF and JavaBean
I guess there is no Answer to this Question Well FYI.. for anybody interested.. I ran a test switching JVM's from 1.3.1 to 1.4.0 ..The peformance gain was like 41% over 1.3.1 JVM...This is really interesting... Anybody else ran any tests, what are your results? If you need any help testing.. let me know. In CFMX admin, under your JVM details.. there is a line which says.. Java JVM Name:Java HotSpot(TM) Client VM Does anybody know what this does FOR CFMX if it does anything at all.. Anybody from MM can explain this? Joe PS: HotSpot is a performance JVM.. voted 2nd runner up as best JVM.. in JDJ.. BTW.. Oracle's JVM was the BEST.

RE: Passing Arrays
Your code below should work fine - you probably have an issue in your
UDF code. Can you share that?

Subject: Passing Arrays
Is there a way to pass an array to a UDF?
Example:
myFunction (myArray) {
..//
}
thisArray = ArrayNew(1);
myFunction (thisArray);
If I do it this way, CF complains about not being able to convert
complex values.
Thanks

Re: Passing arrays to a popup
first off js is case sensitive so use function not Function
also what do you want to do with the values? prepolulate another form or
what.
To loop over the elements collection you would have something like:
var foo = new Array();
for(i=0;iopener.document.forms[0].elements.length;i++){
foo[i]=opener.document.forms[0].elements[i].value;
}
This would give you an array foo with all the elements values. Of course if
you were using netscape and dropdowns they don't have a value but otherwise
you are ok. Decent js guide at:
