Thanks for the reply Griff.

Your response was 99.9% correct!

The only thing missing was that I had to make sure that the base form (the tiny one that Visual Studio creates) was enlarged large enough to hold all that the CTRL+V was going to paste into the form.

Once I did that, everything tansferred perfectly.

Thanks again -- huge help

Is there a way to get a "\n\n" down to a single "\n"?

Umm Hi,
This is a question related to yesterdays "Blank lines in a rich text box from a Serial Device, am I getting rid of them correctly....." I have found an oddity with the data I am reading in at odd times I get "\n" appearing (it's serial data) I am using a foreach() loop to split up the data coming in with one one the delimiters being "\n" I'm guessing that as there are two next to each other it see one kills it and lets the other pass,
Resulting in a blank line. If I use

if (subString == "\n")
       break;

with out effect
I have got it so it creates the a save file as

Quote:
8/30/2012 3:51:21 PM| LD:0002=H10003027710004940129142|
8/30/2012 3:51:21 PM||
8/30/2012 3:51:21 PM| LD:0003=H2000749724900011250077140|

What I need to do is stop the above line appearing in the save function.
The foreach to assemble the string is

foreach (string subString in Unit_Reply.Split(delimeter))
      {
          //if (subString == "")
          //    break;
          //if (subString == " ")
          //    break;
          //if (subString == "\r")
          //    break;
          if (subString == "\n")
              break;
          if (subString.Contains("\n")||subString.Contains("\r"))
          {
              MessageBox.Show("ALERT!!!");
          }
              Unit_Reply_Modded += "\n" + dt.ToString() + "|" + subString + "|";

               //MessageBox.Show(Unit_Reply_Modded);

      }

the commented out lines have been tried and found not to work (also the if Contains does nothing), I was trying to avoid using the StreamReader / Writer and BinaryReader /Writer as I am a little of how they work also I am attempting to read data from a board I read in the past with out using them.

If delimeter is a char[] with one of the delimiters being the '\n' character, then all you need to add is an optional parameter to the String.Split method:

glennPattonWork wrote:
foreach (string subString in Unit_Reply.Split(delimeter, StringSplitOptions.RemoveEmptyEntries))

StringSplitOptions.RemoveEmptyEntries will remove emtpy entries from the resulting String[] which will occurr if there are two (or possibly more) consecutive '\n' characters in your string.

app.config file

dcof30-Aug-12 4:09

In a C# 2010 application, I want to place files in dynamic folder structures that I create in the application. I want to create these dynamic locations so we can place data in the dynamic paths based upon customer name. I also wantto place these dynamic paths in the app.config file.

Thus can you tell me if there is a way to point the app.config file to these dynamic paths? If so can you tell me and/or point me to a reference I can use that will help me accomplish this goal?

The root class for configuration management is the ConfigurationManager

http://msdn.microsoft.com/en-us/library/system.configuration.configurationmanager.aspx[^]

You can google for examples for updating the file itself.

Note that if you want to do this while the application is running and thus AFTER you have already read and perhaps cached settings then you will need to set up a file watch and listeners.

Hi jschell,

Any updates to the config file itself will boot off the user using the site as on saving the file, IIS will try to reload that information, in effect ending all user sesisons. I think it would be a better idea to store this information in an application object which can later on be accessed. Let me know if I was wrong or misunderstood your point.

Thanks and Regards,

Thanks and Regards,
Aby

I make asked to come up with directory paths that look like the followiing:

C://08-30-2012/Customer 1

C://08-30-2012/customer 2

C://08-31-2012/ customer 1

C://08-31-2012/customer 3.

If you can not change the app.config file, how would you change to come up directory path names like I am just displaying?

Well, the first thing I see there is that you aren't basing the directory structure off the customer name. You are basing it off the date first, so your example doesn't match your stated requirements. Which one is right?

You don't actually need to complicate things like this - all you need to do is create a common root path for the customer data, and then put the customers under that root path. For instance:

c:\App Customers\Customer 1\08-30-2012
c:\App Customers\Customer 1\08-31-2012
c:\App Customers\Customer 2\08-30-2012
c:\App Customers\Customer 3\08-31-2012

Then you can just look for the appropriate customer path. Add yourself a little SQLLITE database and you can store the base path in there, along with any other dynamic information you need.

That's web.config, not app.config. App.config typically goes with desktop applications.

First your original post said nothing about IIS nor really even about a server for that matter.

Second however since you already know this then you, presumably, already know that there is not in fact any way for you, in your situation, to write it back to the web.config. So wouldn't that make your original question moot?

Aby Thomas Varghese wrote:

Far as I can determine your original question was about persisting the information. And presumably, since you can't use the config, then there are any number of alternative possibilities for persisting it. Such as writing to a file or a database.

Hi,
I am an intermediate programmer i have working knowledge on databases in various programming programming languages. What my problem is I dont know the basics of database connections till now I have just used copy-paste procedure while connecting databases so I want to know the basics of integrating database in my applications. I need the information right from the begining like

1. What is DataSource?
2. What is Data Provider?
etc. important terms that are required initially when we start an application to integrate database

thanks,
Sudhir.

I need to add
using System.Web.Script.Serialization; but when I try to do add reference , it disbaled in .net component. I am using VS 2008.

I read on internet that it is available in 3.5 but in my visual studio some components of 3.5 are enable but some are disables.

I also search my system for System.Web.Extensions.dll and it is present in v3.5 folder.

Please suggest hwo to add?

You should change the .Net Framework version to .Net Framework 3.5 full, rather than .Net Framework 3.5 Client Profile and then all .Net 3.5 libraries should be available. You can do this in your application properties under the Application tab - Target framework.
