Hi, joeitaliano.

We supported many features from Adobe's Java Script for PDF, look to reference:
http://www.adobe.com/content/dam/Adobe/ ... erence.pdf
And you may run any JS by (see our Active SDK Help, [Reference/JavaScript Support]):

Code: Select all

string result;
ctrl.RunJavaScript(<java_script_string>, out result, 0,0);

Example:

Code: Select all

string js = "var f = this.getField("<theFieldName>"); if (f != null) { f.value; f.value = "myNewValue"; f.value; };";
string result;
ctrl.RunJavaScript(js, out result, 0,0);

- script changes the value of field and prints (to result argument) the value before/after change.

HTH.

thanks it worked great

can i assume then that the your JavaScript implementation is 100% compatible with adobe so i can use the functions in their manual

thanks again

Yes - we endeavour always to ensure such items are Adobe compatible - though always note the caveat that Adobe FREQUENTLY deviate from their own documentation and we have found ourselves spending literally days 'scratching our heads' wondering why something did not work before realising this was the case - so if you come across such a case - dont be surprised.

john

i just received a pdf file that has form fields of fixed length

when i view it with adobe and type in the field it does not allow you to enter more than the box size

however with the sdk and the reader it allows you to exceed the limit

any reason for this

can i send you the file to look at for me

i have no way of working this out

thanks
