Hi,

Does ECL viewer has drag and drop functionality for example we can drag and drop file from windows sever to SAP. So that it can be used later on using BDN.

Thanks.

Regards,

Rajesh.

Just tested it, you can absolutly drag and drop from windoes. I actually didn't know till now. So this is cool. I tested with a simple text file and it is working good.

is the ECL Viewer a third party tool ?

ECL veiwer is a part of the SAPgui implemented as a frontend control. It was developed by SAP jointly with a third party(at least this is what I was told). It is implemented like any other frontend control, like a text editor, or an ALV grid. One important thing, is that you must have the frontend software installed. It is a component of SAPgui. You need to run the installation and select the component ECL Viewer, and install it. Then when you use the class in your program, it will be able to talk to the frontend. Example coding to follow........

Implement this program, it is a cut/paste solution. Again, you must have the ECL component installed on your SAPgui.

            dp_error          = 4 .

Now drap a PDF file from the left container, and drop in the right side. Slick, right?

The ECL doesn't handle every file type, but PDF works good.

Waiting for Code...

Do I need to install ECL 5.1.1 from service marketplace ? Ihave downloaded it from service marketplace though ?

If you have any documents or information, I would be delighted to get it....

Re: Does SAP ECL viewer has drag and drop functionality...

Not sure that that download is the full installation, may be just a patch, but it is worth a try. Try installing it, then run this program.

I ran the code without installing ECL viewver. Got an ABAP dump. Is it due to code or non-installation of ECL viewer.

"An exception occurred. This exception is dealt with in more detail below

The exception, which is assigned to the class 'CX_SY_REF_IS_INITIAL', was

neither

aught nor passed along using a RAISING clause, in the procedure

"%_SEL_SCREEN_O" "(FORM)"

ince the caller of the procedure could not have expected this exception

to occur, the running program was terminated.

he reason for the exception is:

ttempt to access a component using 'NULL' object reference (points

o nothing).

n object reference must point to an object (an instance of a class)

efore you can use it to access components (variable: "ECL_VIEWER").

ither the reference has not yet been set, or it has been reset to

NULL' by a CLEAR statement. "

It is because the ECL viewer is not installed.

I ran the code and it worked for me. I am curious to know what is this used for ? I could see the files in my 'C directory, view them, close them. but what's the use of this in SAP ?

Re: Does SAP ECL viewer has drag and drop functionality...

RichHeilman — Thu, 01 Mar 2007 20:10:08 GMT

I'll tell you. We use the ECL viewer in exactly two programs at my company, but they do the same thing.

For example, the customer faxes a drawing/form to a fax number. This fax number is tied directly to our RightFax software which takes the fax and creates a .tiff file on our server. So now we have a soft copy of the incoming fax instead of a hard copy.(we love trees) Now my program reads this directory into a tree like structure on the left and the user can double click the files, when she does, the image of the fax opens in the right side. Now she can evaluate the drawing and what the customer is asking for and process accordingly, all done without a sheet of paper.
