I made a sample database using this control in  another thread.  Check it out and see if it would suit your needs.

Thanks Ron,
The example I had seen it, sadly lacking how to use the signatures in a report ...
Can you have any idea ?

IrogSintaCommented:
Okay, here's a revised demo that has signatures in a report.  One quirk I haven't been able to figure out is after signing once, you have to reopen the form to sign again.  Other than that, it seems to work without any problems.

Thanks Ron! Do you know a way to check if it was written signature?

IrogSintaCommented:
I don't understand what you mean by written signature.

marcozamperlinAuthor Commented:
Sign: a person's name written in a distinctive way as a form of identification in authorizing a check or document or concluding a letter.

IrogSintaCommented:
Still not sure what you mean.  Do you mean to check a signature against one that's on file?  If so, I don't know how you would do that.

I have another problem: I created a report with a InkPicture control. In report view mode, the signature is displayed correctly while in print preview mode no. Do you have any idea?

IrogSintaCommented:
Are you certain about which view it displays correctly in?  Print Preview is where it you should see the signatures since this is the view that shows what it would look like when printed.  Report view does not fire events so you wouldn't see the signature there.

I have write this code:

Option Compare Database
Option explicit

Private Sub LoadSignature()

Dim newInk As New InkDisp 'need new object to load new ink
   
    If Not IsNull(Me.Sign) Then
        newInk.Load (Me.Sign)
        Me.InkDisplaySig.Ink.DeleteStrokes
        Set InkDisplaySig.Ink = newInk

    End If
    InkDisplaySig.AutoRedraw = True
End Sub

Private Sub Body_Print(Cancel As Integer, PrintCount As Integer)
      LoadSignature
End Sub

Private Sub Report_Load()
      LoadSignature
End Sub

Sign is the Ole field.

In report view the signature is displayed.
In print preview not.

You need to follow the sample db I gave you.  Look at the OnFormat event of the detail section of the report.

Your sample that I have does not have a report but only a table and a form ...

Oops, I thought I uploaded my revised demo in my second post.  Sorry about that.  Here it is:
SignatureInk.accdb

This version works well. Question: Is it really necessary to use a temporary file?
0
 
IrogSintaCommented:
It may be possible to do without the temp file, perhaps with the Renderer() method.  Unfortunately there aren't that many examples provided out there in order to figure out how to do this.
