ByRef in com?

2 posts in this topic

Hello everyone.

I am having a little problem with a com object that I'm using. It requires me to pass an array in a method as an argument, but it needs it to be passed

ByRef so that it can change it. How can I do that? I do it like this at the moment.

$Raga1.Recorder.Monitor.GetDataVb2($Buffer,0,ByRef $indata)

However, I get an error in the expression. What am I doing wrong? If I don't use ByRef, it will pass the array's value and not it's reference, but if I

use ByRef it crashes. What can I do?

Regards

Unfortunately, this is a limitation with parameter passing in COM. All I can think to try is to make $indata a Global variable in your main routine and then insure you use the same variable name in your function. I have not tried this, but seems logical to me that it would serve the same purpose.

It means that what you tried did not produce the results you expected. It begs the questions 1) what did you try?, 2) what did you expect? and 3) what happened instead?
