Re: Why load application so slow during the startup of the system

Hi,

Don't have any syncronize call in the startup function like database/web service call.

Use asyncronize(delegate) call to do the startup functionality.

Regex : 2nd attempt

I trashed the C# forum (in Firefox) last time I posted a RegEx question - so apologies before hand if the screen all goes pear shaped..

This is C# in the loosest sense of the word in that I am using the RexEx class...

My File :-

=======================================================================
D:\\APPS\\23JUL07_1700__PID1520.LOG
--------log end-------------
2007-Jul-25 09:47:10:038 Boring text...
2007-Jul-25 09:47:10:194 Really boring text

=======================================================================
D:\\APPS\\23JUL07_1702__PID2304.LOG
--------log end-------------
2007-Jul-25 09:47:01:475 Some secret stuff 471773.1
2007-Jul-25 09:47:02:085 more secret stuff

=======================================================================
D:\\APPS\\24JUL07_1430__PID8908.LOG
--------log end-------------
2007-Jul-25 09:47:09:850 Important stuff...
2007-Jul-25 09:47:10:007 Critical stuff

Is there anyway to extract the PID and the timestamp in each block in a single regex? The pattern I am using, which gives me the PID is ...

(PID(?<MYPID>\d{1,9})\.LOG)</code>

I can then iterate through a MatchCollection obect returned from RegEx.Matches and process all the PIDS using the MYPID group. But I need the date as well. There will always be three lines following the line with the PID...

I can get the date with

(?<date>^\d{4}-[A-Z]{3}-\d{2}.(\d{2}: ){3}\d{3})

but can't join the two so I get the PID and date for each block.

The space after the colon in the date regex shouldn't be there - it prevents a smiley Smile | :)

from showing.

Any help much appreciated.

<code>(PID(?<nums>\d{1,9})\.LOG)((.*?)\r\n){3}(?<date>^\d{4}-[A-Z]{3}-\d{2}.(\d{2}: ){3}\d{3})

again, remove the space after the colon. (if anybody except me is really bothered!)

I have some weird problems connecting to SQL Server 2005 and I hope you can help me:
I have written a c# app on an acer n300. My app is connected to a SQL SERVER 2005 database. This app works fine. So I decided to install the app on a second pda . Both pdas have wireless lan and windows ce 5.0. But my app does not run on the new pda.

// ConnectionString = "Data Source=192.169.71.10,1433;Initial Catalog=PocketPcDatabase;User ID=sa;Password=server;";
// 192.168.71.10 - your IP address

I have installed Compact Framework 2 SP2, but as soon as I try to connect to the database a get the error SQL Server does not exist or access denied. I am absolute sure that my connect string is OK, as it works on the acer pda. The configuration of SQL Server should also be ok, as I can connect from the acer devices.
Network connection is also OK, as I
can connect with remote Terminal Services to the machine hosting the database without any problems.
Can you give me a hint whats wrong? Are there any cab files that I must install on the pda before SQL Server 2005 Client is working? I only installed .net Compact Framework.

Sorry, I have no project to point you to, but the documentation can be found here[^]. Adjust the properties Minimum and Maximum to determine the interval of the scroll bar. Respond to the ValueChanged event and read the Value property to reflect changes when the user scrolls (or optionally use data binding).

It means you're trying to compare two strings that are in different formats. COLLATE[^] is, from memory, the thing you need to play with. Although I don't see how you can compate Latin and Arabic fonts.

Problem in remoting

Mic Mathi6-Aug-07 20:55

Hi all,

I did a chat application. But I stuck in the finishing point.

I used a windows service as server. This windows service will create and maintain a remoteable object. The clients are connected to this remoteable object using tcp channel. In addition, I implemented an application for the interface of server. This windows application will run on the server machine. Users are added throw this windows application. In addition, the available users and their status will display in this application.

The windows service with startup type automatic will always run on the machine. Whenever the windows application for the server interface started, It will call a function on the remotable object to attach this application to windows service.

remotableObject.AttachServer(this);

'this' will stored in the 'remotableObject'. So whenever the clients become online or offline, they will send a notification to windows service. If the server interface application is running the windows service will try to list the status of users in a list box. To do this, windows service will pass a serialized class of 'users' to server interface application. Everything is ok till here. I could deserialize the 'users' object. Now only one job is remaining is that list the users in a 'listbox' control. But when i call the functions of listbox, the program stop responding. No errors are displayed. Can you guess what is the problem?

Thanks and Regards,

Mic

Hi Mic,
As per my concern, You are going to update the UI (Form item). I would to say, If you want to update the UI then please do it with the help of delegates. I thought yor are update the UI in any event so it going to stuck.

Please go through how to update the UI via deligates.

Oh yes

the scenario I explained above, it happened when the server interface tried to add a user to remoteable object. Its work in an event of server interface windows application. I tried another example, which is not call from any event. It is working. Therefore, as per you said I will use delegates. But how can you understand that it is the problem of events? Actually I didn't understand what is the real problem that's why I ask. Thanks for your precious advice.

Thanks and Regards,

Mic

deserialization problem

Hi there,

if i got an 3 arraylist to be serialize, each with different type(Point[] or int) how do i deserialize them back to the 3 different arraylist accordingly. Should i save the number of items in each of the arraylist? Check the type? What other methods would u suggest?

Thanks in advance.

If you serialize the lists into separate streams, just remember which list resides in which stream and you'll be fine. If you serialize the lists into one common stream, though, make sure you deserialize them in the exact same order they were serialized.

i need to save all the arraylists into a common arraylist and then serialize it because i want to save it into a file. Is this correct?

Below is part of the code i wrote:
In Save()

<br />
ArrayList arr = new ArrayList();<br />
<br />
arr.Add(Arraylist1);//arraylist containing Point[]<br />
for(int i=0;i<br />
{<br />
GraphicsPathData gpd = new GraphicsPathData((GraphicsPath)PathList[i]);<br />
Stream gpdStream = GraphicsPathData.Serialize(gpd);<br />
arr.Add(gpdStream);<br />
}<br />
<br />
arr.Add(Arraylist1);//arraylist containing enum<br />
<br />
formatter.Serialize(myStream, arr);<br />
myStream.Close();<br />
<br />

in OpenFile()

<br />
ArrayList arr =new ArrayList();<br />
			if (openFileDialog.ShowDialog() == DialogResult.OK)<br />
			{<br />
				filename = openFileDialog.FileName;<br />
				Stream myStream = openFileDialog.OpenFile();<br />
				if (myStream != null)<br />
				{<br />
					IFormatter formatter = new BinaryFormatter();<br />
					arr = (ArrayList) formatter.Deserialize(myStream);<br />
					myStream.Close();<br />
<br />
.................

However the problem here, how can i separate the arr into the correct arraylist?

Thanks for your help

You don't need a common arraylist to serialize several arraylists into one file. Just make several calls to formatter.Serialize passing the same stream:

formatter.Serialize(myStream, arr1)
formatter.Serialize(myStream, arr2)
formatter.Serialize(myStream, arr3)

To restore the arraylists, make the calls to formatter.Deserialize in the exact same order:

arr1 = (ArrayList) formatter.Deserialize(myStream);
arr2 = (ArrayList) formatter.Deserialize(myStream);
arr3 = (ArrayList) formatter.Deserialize(myStream);

hi there,
Thanks for the reply. Your solution works perfectly for binary serialization. However, i was wondering, does this concept works the same if i want to use XML serialization?
Thanks.
