Using a sig tablet (have no experience) but maybe the sigTablet itself has a uniqueId you can retrieve from the attached device which you could use as the 'prefix identifier' in my suggestion below.

I usually end up going for a datetime stamp and prefixed with some other identifier, like the current logged in userId.

Other ideas I've seen on this forum have been using a central SQL server, or web service to send a uniqueId value to the form on open/submit/save.

When using date-time stamp I remove the extraneous chars (using xpath translate function) e.g. 2011-05-30T13:10:55 becomes 20110530131055. There is risk of someone else generating the exact same time stamp though which is why I prefix with the other identifier.

jscript unique ID

Hello! I created an electronic sign-in sheet with InfoPath and an e-sig lcd tablet. Using jscript code provided by the e-sig tablet vendor I was able to create a jpg of the signature and link it to the document. The problem I'm having now, because the file name is hardcoded into the control (C:\SigImage.jpg), is that the most current SigImage.jpg is being referenced to all the signed documents.

Is there a way in jscript to generate an unique ID using something similar to a now() to give each jpg it's own unique file name to link back to the form? Here is the code behind my button:

function CTRL1_5::OnClick(eventObj)

{

//This button initiates the tablet for signing

sigObj.InitSigPlus();

sigObj.OpaqueMode=true;

sigObj.TabletState=1;

}

function CTRL2_5::OnClick(eventObj)

{

//This button is pressed after the tablet is signed, it attaches the image of the jpg to the InfoPath document

sigObj.TabletState=0;

sigObj.ImageFileFormat=4;

sigObj.ImageXSize=200;

sigObj.ImageYSize=30;

sigObj.ImagePenWidth=11;

sigObj.JustifyMode=5;

sigObj.WriteImageFile("C:\\SigImage.JPG");

var objField1 = XDocument.DOM.selectSingleNode("//my:myFields/my:field1");

objField1.text = "C:\\sigimage.jpg";

}

If I could somehow generate an unique ID and pass it as a variable to the WriteImageFile() function and associate it back to objField1.text then I think it might work. I would greatly appreciate any insight, suggestions, advice anybody can spare!

Thanks!
