    Is it possible to assign a very big string to the DocumentProperty? what's the size limit of DocumentProperty?

    I try to pass data from IE at the resource manager back to XMetal.

    All I can say at this point is that in theory there should be no limit. How big is your string?

    A quick stress test in XMetaL Author 6.0 shows that a million characters is not an issue. It might take quite a while to build the string (the pure JScript looping part).

    [code]// XMetaL Script Language JScript:
    var curDoc, curDocProps;
    curDoc=Application.ActiveDocument;
    curDocProps=curDoc.CustomDocumentProperties;
    bigStr = “”;
    for (i=0;i<100000;i++) {
    bigStr += “1234567890”;
    }
    Application.Alert(“bigstr.length = ” + bigStr.length);
    curDocProps.Add(“cdpropsBigStr”, bigStr);
    var s = curDocProps.item(“cdpropsBigStr”).value;
    Application.Alert(“cdpropsBigStr.length = ” + s.length);[/code]

    If you increase the number of iterations (or increase the string that is being added) you can easily test bigger values. Note that this is a very inefficient way to build a string in JScript so it will take exponentially longer the more times you iterate through, but it is an easy way to stress the system. So, if you have a large text file on disk you might use Application.FileToString to read it in instead.

    Official word from our dev team is that the string size is only limited by the available application-heap memory at the time of the operation.

    What is the limit you are seeing in your case?
