How to make digital signature value readonly after page submission

Hi,

I have a page which has digital signatures in that. Once I submit the page the entire form is flattened and sent as a email attachment to the recipent.

Here when the flattened copy is sent I can see the digital signatures are going to invisible mode. There is a xci configuration file to make the value to

invisible mode.

Now I want to make the signature value readonly before submitting the form so that no configuration will make it preserve to its previous mode.

Let me know if anybody has solution for this.

I am struggling on this on how to make the value readonly.

I tried the following code before submission event. But it didnt work

form1.applicantSignature.access = "protected" ;@forumnotifier Newsgroup_UserAmy_WongWoojinDebbie

Thanks a lot in advance.
