Re: [twsocket] Converting Send() and Receive() to Sync
If you have an access violation you must be trying to access some invalid memory. Debug it to find out where it occurs and figure out why.

Re: [twsocket] Converting Send() and Receive() to Sync
I thought you could suggest an implementation fix as the design and code is simple and according to the KISS principle (Keep It Small and Simple) it SHOULD work.. ;) Best Regards, SZ - Original Message - From: "Francois PIETTE" <[EMAIL PROTECTED]> To: "ICS support mailing" Sent: Sunday, September 25, 2005 5:34 PM Subject: Re: [twsocket] Converting Send() and Receive() to Sync >> Ok, I see your point.

Ok, I see your point. But still my code seems to be a simpler design. Did you look at it? It is just ~50 lines!

Re: [twsocket] Converting Send() and Receive() to Sync
You may run the ISAPI into the main thread, and having ICS code run into a worker thread with a message pump so that it can work asynchronously as usual. The ISAPI thread can then be blocked while ICS is doing his work and signal the main thread when done. -- [EMAIL PROTECTED] http://www.overbyte.be - Original Message - From: "Fastream Technologies" <[EMAIL PROTECTED]> To: "ICS support mailing" Sent: Sunday, September 25, 2005 3:21 PM Subject: Re: [twsocket] Converting Send() and Receive() to Sync > - Original Message - > From: "Francois PIETTE" <[EMAIL PROTECTED]> > To: "ICS support mailing" > Sent: Sunday, September 25, 2005 3:03 PM > Subject: Re: [twsocket] Converting Send() and Receive() to Sync > > >>> http://www.fastream.com/ics/WebConnection.pas >>> I have been trying to convert a professional ISAPI 6.0 component to ICS. >>> Scripts are now running but as for the internal logic of it, it needs >>> sync >>> read and write procedures.

Much better to avoid sync functions.

Re: [twsocket] Converting Send() and Receive() to Sync
Hi Perhaps a small bug??? In the .pas code the variable "DoneFlag" is not initialized before calling "WaitUntilReady(DoneFlag);" and then it is tested inside the while loop. The result of the test "if DoneFlag then" is depending on trash from memory allocated in the stack []s Arnaldo Fastream Technologies wrote: >For some reason the 2kb attachment did not go through.
