Chuck,

I have a problem where at times my connection goes away. I have not  

been able to figure out how to check and see if it is still valid.

I don't use 4D Open anymore, but I did something like this when I did  

use it.  I found the connection would often time out when processing  

information in between 4D Open commands.  Therefore, before I called  

any series of 4D Open commands, I would call this wrapper:

If (Not(âóävServerID>0))

$vErrCode:=op_Connect ($vProcess)

Else

$vErrCode:=OP Open connection  

(âóävServerID;vConnID;âóävStoreName;"user";"pw";$vProcess)

End if

$0:=$vErrCode

Where <>vvServerID was the ID to the server I was connecting to,  

$vProcess, was the name of the process I wanted to created on the  

server, and the "op_Connect" method looked like this:

vCompID:=op_GetCompID ("TCP")

$vErrCode:=@OP Load network component (vCompID)

$vErrCode:=$vErrCode+OP Find 4D Server  

(vCompID;â&oacute;&auml;vParCorpServerIP;â&oacute;&auml;vServerID)

$vErrCode:=$vErrCode+OP Open connection  

(â&oacute;&auml;vServerID;vConnID;â&oacute;&auml;vStoreName;"user";"pw";$vProcess)

$0:=$vErrCode

I believe OP Load network component might be obsolete now, because I  

haven't used this for quite some time (I rewrote everything using web  

services, and it's INFINITELY faster).  That said, this code did work
 

flawlessly for a very long time.

HTH,

Mike

Hi all,

I have a problem where at times my connection goes away. I have not  

been able to figure out how to check and see if it is still valid.

Environment 4D 2004.7 latest release on both servers

I do a OP Open connection

Is there any way to check to see if connection is still alive?

I tried OP remote connection status hoping it would work, but it does  

not.

TIA and Regards

Chuck
