How to import PICTURE (BLOB) from an External Database into an Efficy PICTURE field ?

Tue, 03 Oct 2017 13:28:15 +0000

Dear all,

I have to import PICTURES into Efficy PICTURE fields from an External ORACLE Database into an Efficy Database by using a Datasync, but the following code is not working (No Error but the PICTURE field stay empty) :

Database.UpdateCategory(EditHandle, 'PROP$BROCHURE', 'F_PIC' + indexPic, DataStore.AsString('PICR_DATA'));

PICR_DATA is an Oracle Blob

Is there a way to base64 encode a database.OpenUrl() result ?

Thu, 24 Aug 2017 20:46:38 +0000

Hi !

Does anyone knows if there is a manner or possibility to get a http request's response encoded to a base64 string ?

We have to display a captcha png (generated with captcha.net) on a guest page, but the problem is that we can see (in developer mode on browser) the ajax call done to captcha.net and this one contains credentials.

I saw that there is the TMagickWand object to display images from disk, but does it work with web paths ?
I tried something like

return "data:image/png;base64," + database.openUrl(url, "")

But it don't gives correct base64, maybe that we should use some kind of encoding on the database.openUrl(url, "") result ? and then concatenate it with "data:image/png;base64," ?

Thank you in advance !

How to save a picture (base64 encoded) in the database through serverscript?

Mon, 03 Apr 2017 08:19:30 +0000

Hello,

For a Customer who uses an external website to add contacts, etc in their Efficy (Summer 2012). Multiple calls are possible like update user, create user, create/modify actions,..

All these calls are posted to the serverscripts in the guestpage. All values are read correctly but we encounter 1 problem with an image.

In the arguments 'picture' is defined and expects an long string (base64 encoded).
For example: "iVBORw0KGgoAAAANSUhEUgAAAdgAAAG6CAYAAACr5VfIAAAACXBIWXMAAC4jAAAuIwF4pT92AAAAGXRFWHRTb2Z0d2..." and this goes on for a while.

As we are in serverscripts, I could not use windows object/functions.

When we save, we are using the next line.

Database.UpdateFields(ContContext, 0,  'PICTURE', picture);

Where picture is saved now is a normal string, I could not convert it to a blob, stream.
Converting the string to the following format did not work as well.

var picture =  "data:image/png;base64, ..."

In db editor I can see the 'hugeblob' of an existing picture of a contact for example, on top defined the content type and below non readable text.

Has anyone already managed to save this to the database as blob?
It would be a great help because of the external website, there are not any other feasible options.

Thanks in advance.
Kind regards,

How importing an blob image field from an eLink database to an Efficy database via DataSynchro

Thu, 21 Apr 2016 07:55:18 +0000

I need to update an image field into a category on Efficy provided by eLink.
By default this code doesn't work.

I tried :

  Database.ActivateCategory(EditHandle, 'DOCU$ORG')    
  var CategoryDataSet = Database.GetCategoryDataSet(EditHandle, 'DOCU$ORG')
  CategoryDataSet.Edit         
  CategoryDataSet.FieldByName('F_VISUEL').AsWideString = DataStore.AsString('F_VISUEL')
  CategoryDataSet.Save

 Database.ActivateCategory(EditHandle, 'DOCU$ORG')   
 Database.UpdateCategory(EditHandle, 'DOCU$ORG', 'F_VISUEL', DataStore.AsString('F_VISUEL'))

In all cases blob is not updating properly. File seem corrupted.
We tried to do a smartCompress but not recognize into a DataSynchro.

Any idea to transfer these BLOB ?

In both cases it's an SQL SERVER 2003 connector
