from memory the config file is a read only document for use in the program so no changes are stored to it. Plus if you change it outside the program while the program is running you need to restart the program for the new readings to take place.

You could save the value to another file that is pointed to by the config file.

So it makes more sense not to use the .config file in the first place for settings as these, and opt for a normal text file.
Correct?

No the config file is used for settings that apply to the application for ti's life time. Ie if you only want it to connect to a specific database or which error log source to write to.

For user settings it is not recommended I use it for some settings and point to other files from it.

google and you get some interesting results.

Ok thanks for the info. Will save the settings in a seperate text file then.

IMO, this is bad design. The app.config file is not meant for that purpose.

You may want to save the last record retrieved somewhere else. Maybe in the database itself, in another table. This would especially work well if you are using a stored procedure to retrieve the records.

Another solution would be to add a flag to the table where you retrieve the records to mark those who have been read.

It's not storing the value in the app.config file.

The settings object that you have added in visual studio automatically generates a bunch of code that uses the System.Configuration stuff.

Settings that you have chosen to be "Application" settings are stored in the app.config file, and cannot be modified in code. Settings that you choose to be "User" settings have their default value placed in the app.config file, but when you save a change to the value, the save is made to a config file stored in the current users local settings directory. ("C:\documents and settings\username\local settings\apps\appname\appversion\...." I think)

At runtime, when you request a value, the CLR first looks in the c:\docs & settings\... location to load a value from there. If there isn't anything there, it then goes to the app.config file, and finally, if there is nothing there, it uses a default value that is hard coded into the app.

This is why your app.config file always says 0. This is just the default value that is used when no user specific value exists.

Switch Statement Help

Hi All

I'm new to C#, and i was wondering if something was possible. I have a switch statement where i want several criteria to lead to 1 bit of code, and another to lead to another etc.
Is there an easy way of doing this? or will I have to code write the same code out for each criteria?

Please help... Thanks... Big Grin | :-D

oooo, the Jedi's will feel this one....

As long as you have nothing in between, you can fall through case statements in C# using:

switch (myItem)
{
  case 1:
  case 2:
  case 4:
    DoSomething();
    break;
  case 3:
  case 5:
    DoSomethingElse();
    break;
  default:
    DoSomethingElseAltogether();
    break;
}

As soon as you put something between two of your case conditions, you have to fall back to the normal way of doing things.

Put each 'bit' of code in a separate method and call the required method from the relavent case.

[Edit] Sorry, misunderstood the post slightly

Use fallthrough as Pete suggested.

The simplest way is to put your "bits of code" as functions

switch( blah )
{
  case 0:
    FunctionA();
    break;

  case 1:
    FunctionA();
    break;

  case 2:
    FunctionB();
    break;

}

etc

Hi
Can some one tell what is the right algorithm to use Encrypt any files in C# and that need to be decrypted in Java by using key ? Show me some samples if you have..

Thanks

As long as you are using algorithms that both platforms understand, then there shouldn't be a problem. You could use SHA-1 for example.

Process.Start() parameter with space char problem

Hi,
here is code line
Process.Start(@"C:\test.exe", @"C:\Temp Dir\sequence.seq");

the thing is the second string, because it has space in the directory name
the test.exe failes to open the file

i've changed the location to : C:\sequence.seq and it works fine
so it's not the file problem

how can i handle the sapce in the string??

thanks Smile | :)

how to get out from the outer for

erdem0117-Mar-09 0:16

how can i get out from the outer for in a for-for-if situation.
For example
for...
{
for...
{
if...
{
break;
}
}
}

The break only breaks from the inner for, i want it to break from the outer for too.
Could you help.

you have to break it twice or use goto

for (int a = 0; a < 5; a++)
{
MessageBox.Show(a.ToString());
goto LoopBroke;
}
LoopBroke:
MessageBox.Show("Loop completed");

Continue[^] also only breaks a single loop. You could add a flag called 'done', check this in the outer loop, and do a second break if it's true. Or, you use a goto[^].

Disclaimer: the goto suggestion should not be taken seriously Smile | :)

You can't (See the reply from XMen)

You could consider restructuring the loop to use a while loop instead. You might find if you structure it differently that you don't need the break.
