i would like to ask if any one of you guys have tried integrating a fingerprint scanner into powerbuilder? I have a device (digital persona u.are.u 4500) with SDK cd included and coding samples written in vb, java, c++, but no samples for powerbuilder, but atleast i could see its supplied com objects on powerbuilder's insertable oleobject control. (I am using powerbuilder 10.5 on XP machine)
Using VB, I did try saving some of my fingerprint templates on mysql database as well as verifying these saved templates, and everything works perfectly ok. What i would like to do now is to execute the 'verification' in Powerbuilder by using this oleobject 'digital persona fingerprint verification control', but somehow i could not get this one working..
Here is my script, pasted on 'on_complete(oleobject pfeatureset, oleobject pstatus) returns nothing' event of this ole control:
string empcode int constat1, constat2, constat3, status long FARAchieved blob dbfpsample, fpsample oleobject Templ, Verify, Res
empcode = 'EMPC1' status = pstatus.status
if status = 0 then //successfull selectblob finger_sample into :dbfpsample from employee_fpsamples where emp_code = :empcode;
//create instance of DPFPTemplate Templ = CREATE OLEObject constat1 = Templ.connecttonewobject('DPFPShrX.DPFPTemplate') if constat1 < 0 then destroy Templ MessageBox("Connecting to COM Object Failed 2", "Error: " + String(constat1)) Return end if
Templ = Templ.deserialize(dbfpsample)
Verify = CREATE OLEObject constat2 = Verify.connecttonewobject('DPFPEngX.DPFPVerification') if constat2 < 0 then destroy Verify MessageBox("Connecting to COM Object Failed 2", "Error: " + String(constat2)) Return end if
Res = CREATE OLEObject constat3 = Res.connecttonewobject('DPFPEngX.DPFPVerificationResult') If constat3 < 0 then destroy Res MessageBox("Connecting to COM Object Failed 2", "Error: " + String(constat3)) Return end if
Res = Verify.verify(pfeatureset, Templ) FARAchieved = Res.FARAchieved messagebox("Res.FARAchieved", FARAchieved) If Res.Verified = True Then messagebox("Verified", "Verified") else messagebox("Not Verified", "Not Verified") End If end if
Calling on this function :Verify.verify(pfeatureset, Templ) somehow returns 'error calling external object function verify...', and i could now figure out why is this so since this function is visible when viewed on powerbuilder's object browser (under programmable objects). I even tried Verify.object.verify(pfeatureset, Templ), but fires back the same result. And beside i am able to connect to the other 3 objects since variables constat1, constat2, and constat3 is giving me back 0 as result. I even tried calling the DPFPVerification's other function without error. But somehow this one, i don't know why =(... DPFPVerification's Verify function has this parameter when viewed on object browser: oleobject Verify(oleobject pfeatureset, oleobject pTemplate)
Could someone give me a clue why this is happening? Am i missing something? or am i passing the wrong type of arguments to this function? Any response from you guys will be appreceiated much..
