I have been monitoring my system for a few hours now. I am beginning to think Dan's
issue is not with calling the web control at all, but related to the timer eep. Having several users running my compiled HHMain.exe for several hours, I have seen no increase in memory. This app is constantly changing forms, conducting database inquiries, adding new rows and printing. No memory change or increase to speak of. Grader.exe has went from 69,000K when I first started monitoring to over 284,000K at present. This app calls no external form, but DOES have a form timer that calls another form which has an On After Start EEP that conducts data manipulation and then closes. The main form's timer calls this routine every 10 seconds. The routine calculates data from a temp table, refreshes screen data and then writes the manipulated data to a permanent table. No outside controls involved anywhere on the form. The timer function is the only type of control that Grader.exe has that HHMain.exe does not. So it almost certainly is related to the timer eep and/or it's content programming. However, memory does not increase every 10 seconds, (the timer fires every 10 seconds) so I still am not 100% sure what is causing this. I will continue to look at my code, how the form is called, closed etc. etc. as well as monitor the memory usage. (Grader.exe has increased from 284,000K to 294,000K in the time it took me to write this email) While I am not having any significant problem (GRADER.exe is ran over 10 hours a day then shut down, it does not need restarted during the day at any time) this is something of interest. -Bob ----- Original Message ----- From: "Dan" <[email protected]> To: "RBASE-L Mailing List" <[email protected]> Sent: Wednesday, February 17, 2010 12:41:14 PM GMT -06:00 US/Canada Central Subject: [RBASE-L] - Re: Memory Usage out of hand Dennis you are right with my first test. Originally I would just refresh the web content... Memory usage increased Then I tried a closewindow, start new form... Had that in a wrong spot, and opened more and more forms. (my bad) Memory usage increased Now the start eep that calls the form originally is set up like you are suggesting... completely closing the form on each iteration of the loop. Memory usage increases. I am guessing the ONLY way to get the memory to reset is to close R:Base. If that isn't the case, that would be best for me as I don't know how to open an instance of R:base to a particular monitor. Without fixing this, This application uses up memory so fast that twice a day things fail. Have to manually start and stop it. Not good for an automated process.

You should never have code that calls another form after closing the form. The fact that the memory is released when you completely exit your routine is a hint. Instead, set up a loop which calls nextelshuttle. The nextelshuttle timer should just closewindow after 15 minutes. No other code should be rum after closewindow. This way, nextelshuttle will completely close and release memory before being called again. You will need some way of setting vQuit to �YES� at the end of the day or when a button is pressed on nextelshuttle Label Loop set up some vars... set var vQuit = �NO� edit using nextelshuttle if vQuit = �YES� then goto Endloop else goto Loop endif Label EndLoop Dennis McGrath From: [email protected] [ mailto:[email protected] ] On Behalf Of Dan Sent: Wednesday, February 17, 2010 11:59 AM To: RBASE-L Mailing List Subject: [RBASE-L] - Re: Memory Usage out of hand Ok, I made your suggestion work, and closewindow is working now, but I think I need to actually close R:Base to free up the memory? (Memory usage goes up by 50,000 k every loop) So, if that is the case, how do I have R:base open to a particular screen (I run a 4 screen setup here and the app I am working on has to be on the upper right, or Monitor 3) At 11:30 AM 2/17/2010, you wrote: Ok, Yes, Rbase Dat calls up the form: set up some vars... edit using nextelshuttle exit Nextelshuttle form timer does the 15 minutes, and calls an internal eep That eep, does : Closewindow run nextelshuttle.dan return The nextelshuttle.dan does lots of database stuff, and then edit using nextelshuttle The closewindow does not close the window, but a second form is generated (and third and so on for each loop) If you close the latest loop, all forms close. No memory is released till all forms close. What am I missing? Dan At 11:00 AM 2/17/2010, you wrote: Somewhere you have a program that calls up your form, maybe RBase.dat or something else. Do the following (or something like it depending on how your system works): your program: LABEL formagain SET VAR vExit TEXT = NULL EDIT USING nextelshuttle IF vExit = 'yes' THEN EXIT RETURN ELSE GOTO formagain ENDIF RETURN In your Nextelshuttle form: You would have a button to exit the form totally; that form's eep code would be: SET VAR vExit = 'yes' CLOSEWINDOW RETURN And somewhere there's code that does the 15 minute timer. In that code when you've reached the 15 minutes, the eep code would just have: CLOSEWINDOW RETURN or you can use the pre-defined "exit" action. Important: you need the "return" even if you just have closewindow on there. Karen So, now that we have surmised that my memory issue is the use of IE, I am trying to find a way to have the program close and reopen the form each loop through. Closewindow doesn't seem to be my answer. Anyone have any good ideas? Problem: I run an instance of R:base that opens just one form 'edit using nextelshuttle' The form has two objects, a clock and a web object that displays a city map with all our technicians on it. that form has a 6 minute timer to run an eep that refreshes data, imports info to the database, after the eep, the web refreshes. (this is where the memory loss is) I was hoping a closewindow would work, but I cannot make it close the form and restart a new form. I suspect though that I would need to close that whole instance of R:base to free up the memory. Thoughts?
