hi
i have database on sqlCE 75.6MB with 600,000 rows that has one table with 3 columns
A - lenght 13 (text)
B - lenght 20 (text)
C - lenght 21 (text)
i open the connection like this:
bool OpenConn()
{
try
{
Conn = new SqlCeConnection(String.Format(@"Data Source={0}\
{1}", PathI, "MyDB.SDF"));
Conn.Open();
return true;
}
catch (SqlCeException err)
{
MessageBox.Show(err.Message, "Connetion error");
return false;
}
}
the problem that it take a long time to open connection.
is there any other way for open and work with big database ?
i work on sqlCE for Windows-CE or Windows-Mobile in C#
thanks in advance

We've had no problem with opening connections to databases up to 250mb on devices. Our connection string looks like.....
"Data Source = \Storage Card\our_db.sdf;Max Database Size = 500;Max Buffer Size=4096;File Mode=Shared Read;Persist Security Info=False;"
Opening the connection shouldn't be slow, I'm not sure what the default max size is but try specifying size, buffer and mode to see if it helps.

I have a friend who sells various paper specifications to a very specific market.
He's now thinking of delivering this same content to Android or iPhone users.
He has all sorts of requirements around payment and copyright and is wanting some broad-brush advice on what's required, how long it might take, etc.
My question is "What online resources do you know of that might assist me in providing him with such advice?".
FWIW, this is not paid work for me or for him.
Many thx.

My advice is to ask the question about if its worth it, money wise.
You cannot develop iPhone on anything but a Mac (not properly anyway) but you can develop Android on a Mac using Eclipse or MOTODev. So my advice would be to use a Mac.
You'll also need to pay Apple and Google ~$100 each for developer licenses.
You'll also need some devices to test on.
Do the sums and if the answer is still yes...
No online resource will be able to provide you with such advice, only experience will tell you. Unless you know his exact requirements its like asking how long is a piece of string.
If I was to relate mobile development to say WPF I'd say it'll take about the same time plus learning curve. If you already have Java and Objective C experience, the curve isn't great. If you don't, I'd add min 2 months.
"You get that on the big jobs."

I want to do apps of ios in windows 7 os. as Im not having mac pc. Please give me details or easy steps of intsallation.

You need a simulator first - try this[^] out.
|
|
|
|
|
The note at the bottom mentions it's not an actual iPhone simulator, just a safari simulator.
So it's fine for testing mobile websites, but not actual apps.

Hey Guys,
I want to create a simple app for my Windows phone to open a remote connection to my Desktop Computer.
Is there any good article or suggestion on how I can do this? anything that can help to get me started.
Thanks
|

Windows Mobile devices do come with remote desktop, so you should not really need to build an application.
See this tutorial[^] that explains how to use Remote Desktop.
|
|
|
|
|
Windows Mobile does, Windows Phone 7 does not.
|
|
|
|
|
Windows Phone 7 does not have native RDP support.
Your best bet is to start from the official protocol specification in the MSDN[^].
Unfortunately implementing the whole protocol is not a trivial task even if you want to implement only basic functionality (i.e. graphic and mouse).
|
|
|
|
|
Hey,
Thanks for the link.
Do you have any links to tutorials using this protocol?
Thanks.

Hi there,
I'm thinking about making my own type of Siri-like app but supplying a different voice.
Even if it's not as comprehensive as Siri, I'm thinking about it as an interesting side project.
Is there anything out there like dev libraries or products anyone would suggest to help with the development?
Thanks,
John
