Hi,

I am using a web service to retrieve a picture from cloud. The picture is stored in a blob.

I can show the picture using the picture object. Now i need to the following three tasks

1. Save the picture

2. Email the Picture.

I am not sure how i can do that. Any help would be appreciated.

Using PB 2017 R3 Build 1858.

 

Thanks

My email example has the ability to email blobs directly, you don't have to save it to a file first.

for 

1. Use FileWriteEx()

integer li_FileNum
blob emp_id_pic


SELECTBLOB salary_hist INTO : emp_id_pic
FROM Employee WHERE Employee.Emp_Num = 100
USING Emp_tran;


li_FileNum = FileOpen("C:\EMPLOYEE\EMP_PICS.BMP", &
StreamMode!, Write!, Shared!, Replace!)
FileWriteEx(li_FileNum, emp_id_pic)

FileClose(li_FileNum)

 

For 2, I suggest you download one of Roland's examples on how to send email with smtp. It includes the sending of attachments: http://www.topwizprogramming.com/freecode_emailsmtp.html

or you can check on how to send email with MAPI (I don't recommend it), or you can use Outlook and OLE to send email.
