File Transfer from deskop to PDA thro TCP\IP

Hi All,

I am trying to pass a text file from desktop machine to PDA thro TCP-IP protocols. It follows Server (on desktop machine) and Client (on pda) architecture. File is converted to bytes and will be pushed to network stream. The client on PDA will receive the bytes and store it on queue and writes the file on PDA. The operation is accomplished through threads on both Server and client. Applications are developed on MS Visual Studio 2005 (C#).

For large files like 1024 KB or having lines about 15000, it takes around 15 minutes. Can anyone give a better idea to transmit files from desktop machine to PDA using TCP-IP protocols.

Thanks in advance

Maybe using compression would help?|||

Hi Erik,

Is it possible to provide more details or links regarding Compression techniques that can be implemented on PDA applications?

Thanks in advance,

Boss

File share delivery

Hi All,
I am new to SQL 2005 Reporting Services. I have done the reports and now I
want to publish them to a folder in then local machine. I even tried that. I
created a subscription and when it is to rum gives an error "Unable to write
file <abc>, Report Server Configuration error, see log files for more
details". I am not able to understand the problem. Can any one of you please
help me what to do in this and get my problem sorted.
ThanksRajeev,
1. What does the log say? Did you look?
2. Did you specify a UNC path to the folder?
3. Did the user you set up for the subscription have rights to the folder?

I think Your folder which contains report files having Readonly. Check it
out by opening Properties of folder and uncheck read only box

File Headers SQL Express

I apparently have corrupted my file header on my database, and then copied it to my backup database.

Is there some way

1. to have the machine recreate the file header automatically? and fix it so that I can use the database

or

2. a back door into the database so that I can get the text files of my database to reconstruct the database from scratch.

The error mesage I receive is:

Database schema could not be retrieved for this connection. Please make sure the connection settings are correct and that the datase is online.

the header for fil c:\inetpub\wwwroot\nappapfinal\APP_Data\ASPNETDB.MDF is not a valide database header. The File Size property is incorrect.

Thank you

Unfortunately, if the header records within a database file are corrupt, that database is toast.

I'd ask about your most recent backup, but from your question I'm guessing there isn't one.

well the problem was that I was backing up the db when this happened so both were toast. I had a third back up which will have to do however when I uploaded that one I developed a problem with adding users to the db through the web interface... below is my error message: do you have any ideas? thanks in advance for you help.

Description: An unhandled exception occurred during the execution of the current web request. Please review the stack trace for more information about the error and where it originated in the code.

Exception Details: System.Data.SqlClient.SqlException: Procedure or Function 'aspnet_Membership_CreateUser' expects parameter '@.TimeZoneAdjustment', which was not supplied.

Source Error:

It looks like a mismatch between the web interface and the stored procedures in the database.

Have there been any updates to the application since the time of the backup you were able to restore?

If so, you may just need to re-apply them, or at least the portion that modified the database contents/procedures.

I tried to update the users through the web admin tool also, but that wouldn't let me add users, just roles and manage rules in the web admin tool which I believe may have locked me out of adding users somehow? throws a different error message see below:
