Check this article for samples how to store images in ISO. http://www.silverlight.net/learn/quickstarts/isolatedstorage/

Thanks.

Ok, thanks.

i got that the problem is because of the increase in database size because im storing images and audios in database. thats why, when the database size increases 6-7MB, it becomes slow and after 14-15MB the application starts for random crashes. Now i'll try to save all these things in Isolated Storage.

can u please tell me how to store Images and Audio file in Isolated Storage.

I think your issue is that your second page (the one you are navigating to) inherits from UserControl instead of PhoneApplicaitonPage. This is known to cause crashes. Could you double-check this please? Also, based on what you are describing I would suggest re-working your large image strategy. BLOBs always require extra care to work with. I would suggest that you store your images in some folder in isolated storage an only save the file name in the database. This will greatly improve performance as you would not have to pull images out until the user chooses to preview it.

I hope this helps.

yes...

when i test it on Emulator, it works slow but fine.

but when i test on Device, and if i've added data of 7-8 MB, and then i navigate to a page where i can view a list of added items,

the APP crashes. if i don't navigate to view the list and chose to add a new account/item, it works fine.

then again, if i go to view the list the App crashes and if it crashed once or twice, it crashes permanently.

Why is it happening...???

Thanks.

Silverlight on Windows Phone does not impose size limits on Isolated Storage, so the 8/9 MB maybe a red herring in this case. When you say application crashes, do you mean it just closes without an exception, correct?

Thanks.

Hye EveryOne,

I m working in Windows Phone 7,

and i have build an Application in which i m using SilverlightPhone Database

In my app, user can create an account where he/she can add name, some basic informations and can add some image or audio recording files as well.

Now when i add, these files and if the size gets more than 8/9 Mb, the App doesn't save the account information and crashes.

And if i again tap on the icon, and starts it again, then it again crashes.

since the Database is created in IsolatedStorage and thus, i tried-

IsolatedStorage.IncreaseQuotaTo(neededStorage);

as said in this- http://blogs.silverlight.net/blogs/msnow/archive/2008/07/17/tip-of-the-day-20-how-to-increase-the-isolated-storage-quota-for-your-app.aspx

(where neededStorage is a long variable and neededStorage = 1024*1024*5;)

It gives System.Exception which says - "An Error Occured While Accessing IsolatedStorage."

Why is it happening..??

Is i m missing something.

Please reply, as its really important.

Thanks in advance.

New Post: Help with a ranged delete

SergeyBarskiy — Fri, 28 Jan 2011 01:43:15 GMT

Could you please post the entire message and stack trace? There is not enough information in your message for me to help you out. The actual line of code that throws exception would be helpful as well.

Thanks.

Sergey

Hello,

I'm trying to use the removerange option, and getting an error:

Here is what i'm doing:

var deleteCP = (from cupr in db.Table<CustomerProducts>() where cupr.CustID == custID select cupr);

(deleteCP.Count() > 0)

{

db.Table<CustomerProducts>().RemoveRange(deleteCP);

Here I'm getting an invalid operation exception in this piece of code:

public void RemoveRange(IEnumerable

<T> range)

{

_raiseCollectionChangedEvents =

false

;

try

{

foreach (var item in

range)

{

Remove(item);

}

New Post: Exception on d.Save

SergeyBarskiy — Sun, 25 Jul 2010 14:20:27 GMT

I would try to remove and re-add the refernce then pointing to your new downlaoded DLL. I would also run clean up on the solution just in case. I am not sure what else to suggest short of looking at your complete solution.

Sergey.

Hi,

I did indeed download the SL version (the .NET one won't work because it's not built against Silverlight) and I unblocked it. Same exception occurred.

From what I see is that you mentioned that you used .NET version, not SL version. Another possibility is that DLL is not trusted on your machine because it came from the internet. To address this issue, right click on your downloaded DLL, go to properties and if you see Unblock button, click on it.

Thanks

Hi Sergey,

As I mentioned, I did download and install the library; but the exception still appears.

This should be all you need to do. Just use Silveright version of the zip library.

sergeybarskiy — Sat, 24 Jul 2010 00:05:26 GMT

You need silverlight version of the library - http://slsharpziplib.codeplex.com/. I will take a look this weekend and see if there is anything else that needs to be done. Thanks for reporting this.

Hi all,

Database works fine -- I can create a new one and add objects, fantastic. But when I call d.Save(), I get an exception that SharpZipLib is not found. (I downloaded the .NET version and added it as a reference to my project, but that didn't seem to help.)

Here's the stack trace. Any ideas how to fix this?

New Post: Table() as a Property

SergeyBarskiy — Sat, 03 Jul 2010 17:54:08 GMT

I finally got time to look into some of the requests (I have been working very long hours for a while). There is not way to make it a generic property without making database class generic, such as.

Database<T1, T2, T3>{

public T1 Table1{get;}

}

This seems like a bad idea to me.

THanks

Sergey.

New Post: Table() as a Property

ashes999 — Thu, 10 Jun 2010 15:50:15 GMT

I know that this is a question of style and preference, but can we turn Table<T>() into a property? It makes sense semantically, since we really are accessing an object, and not using some method to generate/fetch the table.

Also, this has an implication for debugging -- you can't set watches on more than one call to Table<T>(), because it's a function call -- the other ones will grey out and you have to refresh if you want to see those again. Kinda annoying :)

New Post: Deploying DB

ashes999 — Thu, 10 Jun 2010 15:48:53 GMT

I would really like a way to create a DB in one application, and deploy that DB in another application. There are too many (and too large) records for me to manually re-add all the objects in code.

Perhaps you can make the DB serializable to a Base64 encoding, and create a Serialize method (returns the base64-encoded string) and Deserialize method (takes a base64 string, creates the DB) -- this would allow us to "embed" the DB as an embedded resource and load it up.

Pretty please? I really need this feature.
