Checking the valid email add

Former Member — Mon, 25 Feb 2008 03:35:13 GMT

Dear all,

I need to perform the check on a string where it contains email address.

For eg:

abc@yahoo.com - this is a valid email add

@yaho.com - this is invalid email add

qwertyuyu.com - this is invalid email add

Do you think is there any standard FM can perform such check?

Please comment.

Thanks in advance.

FSCHU,

use cl_http_client class and send a dummy http request to the site to see whether its available or not.

check out the following program for sample code

RSWF_TEST_HTTP

NOTE: if you are connecting to internet via proxy and the url you are trying to reach is on internet.

SICF GOTO->HTTP client proxy settings

in global settings tab

check the check box "proxy setting is active"

and in the "HTTP log" tab

enter proxy host name e.g proxy.sap.com....

enter the proxy server port (generally 80)

if required you need to enter

proxy server authentication (uid/pwd)
