And the question ist ??

I think, what you need is how to write the connection string to a file, is that write ?

When yes, then use :
string connectionString = "...abc...";
File.WriteAllText(@"c:\myfile.txt", connectionString);

string connectionString = File.ReadAllText(@"c:\myfile.txt");

You must also encrypt your connection string before write it to a file.
You don't want anybody to know your database password, do you ?.. Smile | :)

You can't make it impossible. If you encrypt it, well, your program would contain the code to decrypt it. And they will have that code.
The same problem applies to all local data and is impossible to solve, though you could make the chain of encrypted keys of arbitrary length to slow the attacker down.

Edit (used to be something here about encrypted connection strings): scratch that, it's just impossible as well. Great. So now we know you don't even need to try to hide your connection string, at least that saves us all some effort.

File.WriteAllText(@"c:\myfile.txt", connectionString);

string connectionString = File.ReadAllText(@"c:\myfile.txt");

thanks but File will be declare as what in this context?

You don't declare File, it already exists.

I would use App.config aswell as SeMartens describes, but if you prefer to use a seperate file other than App.config, why not make the main program retrieve the connectionstring from a seperate class with a static method and just have that as a dll file. Then if the connectionstring should change you only have to replace the dll with a new one. Smile | :)

Urgent Mail Sending Problem

dev sheoran19-Jun-09 2:09

19-Jun-09 2:09

Hi,
I am sending emails with attachment(.txt file) using c#.
I read data from database saved as varchar datatype. I read data in memory stream and output the memory stream as attachment with content type text(.txt file).

It sends emails to gmail, yahoo,hotmail,rediff etc. mail servers with attachment(which is a .txt file) perfectly fine.
(It means there is no problem with code)

But when i send emails to my own mail server it skips the attachment i.e. i get the emails without attachment.

Please help me asap.
What could be the reason?

My mail server IP is 72.9.144.139

Thanks,
Dev

1) Don't mark your post as Urgent, it's rude and will not get any attention from those who could best help

2) Don't include your server IP address on a public forum. Unless you want your mail server to be used for sending spam.

Could it be that your server is blocking the attachments?

Thanks for your precious suggestions.

We use to send emails with attachment to and from our mail server.
We get emails with attachment from other mail servers also.
I don't think that our server is blocking attachment.

Why make it worse by highlighting the fact he left his mail server IP address, not that it's anything important or useful to the outside world, it can be resolved with a DNS request. But either way, why repeat it and take attention to his error?

So why are you posting in a programming forum? Sounds like some setup on your server.

Anyway, thanks for the IP address. I'm sure I could have some fun with that Laugh | :laugh:

How to transfer data without using dataset

Hi,

I just started to work for a retail company where I am supposed to handle large databases. I need to transfer data from AS400 to MS Access where I will use for reporting purposes.

When I use dataset I receive memory exception. Is it possible to transfer data directly without using dataset(means without using virtual memory).

Thanks in advance

Why would they want to transfer the data to Access Dead | X|

Do they realize there are reporting solutions that will work without the transfer. Or at least use SQL Server, Express is free and coupled with SSRS it would be better than Access, IMHO

You could do it with a datareader, transfer one record at a time.

Access can be a very good reporting tool but the problem with many Access users is that they tend to want to import the data into access and then report on it. Instead, you should create linked tables in access and then create parameterised queries on which to base the reports. Doing so will ensure that only the data you're reporting on gets copied temporarily into access

Thank you both,

For sql Server Suggestion; No way, they would not consider purchasing it.

Access, I will create one table that has links to different tables, since the data I am going to use is huge for Access.

SQL Server Express is FREE. Advanced includes SSRS also. You would be setting the company up with better tools and positioning them for better migration. The tools are FREE, only costs a little time to download and install. Rather than having individual copies of Access databases floating around it could be centralized. Better management, more accurate reporting.

EventLog logging with log4net

Jammer19-Jun-09 1:08

19-Jun-09 1:08

Hi All,

I've been poking around Google / Apache.org trying to get to the bottom of this with no luck. There isn't a lot of info anywhere on configuring log4net using pure C# so I thought I'd try here now.

I can log to the "Application" log with no problems. I can also create "MyLog" event log without problems as well, however, writing to "MyLog" fails to actually write an event log entry. The code I'm using to configure an EventLogAppener is:

public static void ConfigureEventLogAppender(string appName, string logName)
{
PatternLayout layout = GetDefaultLayout();
_eventLogAppender = new EventLogAppender();
_eventLogAppender.ApplicationName = appName;
_eventLogAppender.Layout = layout;
_eventLogAppender.LogName = logName;
_eventLogAppender.Threshold = Level.All;
_eventLogAppender.ActivateOptions();

BasicConfigurator.Configure(_eventLogAppender);
}

Has anyone managed to get this working?

Cheers,

Jammer

I assume "my date" is the date of installation. Just comparing the dates is not enough. What if one changes the system date?
