Google maps - 'Out of virtual memory'

Tue, 05 Apr 2011 10:57:58 GMT

Hi,

I've been trying to develop an application that links to Google Maps - However, I keep getting the message "Out of Virtual Memory, allocating 512MB"....I get this a few times until it says that it cannot process the chart due to an internal error.

My question is - Is there anything I can do to help this? Or is it my PC? I only have 1GB of RAM at present. We will be getting new PCs in the next few months with more RAM, - I presume that this will help?

Any ideas?

Thanks![:)]

Hi ,

I have one trick for you. First debug your application performing a limit load of say 10 lines. after debugging gets over, save you application and perform reload. This trick is used in cases when there are Issues relating to RAM. By following the above process your applucation size will be greatly reduced.

Try out the above and it will definately work.

Hi Gaurav,

Thanks for your response. I tried it, but it doesn't realy work.

I've attached the application that I am using. Perhaps you could get it to work on your PC?

Thanks!

Hi,

I have had a look at your app.

The issue appears to be that the latitide for antartica is a wrong or badly formed value.

You can repeat my tests to recreate your problem by follwing these steps:

1. Open the app and let it fail to draw the graph (The memory error will come up a few times, just ok them and wait)

2. Open your second tab, called sheet 1 and place a list box in there for Domicile on Entry (Detailed)

3. Select Antartica on this list box, and then right click the highlighted Antartica and select "Select Excluded" (This is you selecting all but antartica)

4. Switch back to the Main tab and your google graph should now render.

5. If you select Antarica, the app will crash again

If you just want a quick fix, delete the Antartica entry from your original datasources and reload.

Hope this helps,

P.S Is this your data about students in this app, or are you using sample data?
