Window Metro Base64 Encode

The language doesn't matter. If you look down the forums list, you will see that there are various specialities in there - and you are more likely to find the answers in those specialities. So, knowing that you were using Silverlight it would stand to reason that you were more likely to get an answer there than in this forum. You were just lucky that someone who knows Silverlight happened to read the message here.

Had you posted it in that forum, you have more of a chance of getting an answer from someone who knows the technology. By using the wrong forum, you lessen your chance of getting an answer. In future, choose the right forum.

One final point. Please don't use text speak in the forums. You have a full keyboard at your disposal, so use it. Text speak just serves to irritate and can end up with people ignoring your question.

Rename Directories

Hello,

I am trying to understand the easiest way to rename a parent directory and the sub directory at the same time.

Thank you for the help.

I don't think you can. Why is this necessary?

The difficult we do right away...
...the impossible takes slightly longer.

Why at the same time?
Just rename the current and then jump to the parent and do the same? There is no magic button for this type of thing.

I wasn't, now I am, then I won't be anymore.

I'm in C# WinRT in Metro, and I' trying to encode an image. I have this code from a .Net 4 app, but it doesn't compile in 4.5:

private string imageToBase64(Image image, System.Drawing.Imaging.ImageFormat format)
{
using (MemoryStream ms = new MemoryStream())
{
    // Convert Image to byte[]
    image.Save(ms, format);
    byte[] imageBytes = ms.ToArray();

    // Convert byte[] to Base64 String
    string base64String = Convert.ToBase64String(imageBytes);
    return base64String;
}
}

Anyone know how to do this in C# Metro?

Everything makes sense in someone's mind

When you compile this, what is the compilation failure? What message do you get? Which line?

Does it show a compile-time error? If yes, what does it say?

You can use the Word.Interop[^] library.

Database connection pool thr application

Hi...
In my web application, we are using oracle database. my question is connection pool based on web application. Our application end user around 500. for these which connection is better i) create new connection for every request of user. ii) single connection pool via singleton object of the class iii) session based connection pool ( each user has separate connection pool)
which principle is using for web application? can please give suggestion or valuable link to me

--Thanks

I think you would get a better response by posting this in the Database forum; there is nothing in your question about C#.

That's what I'm doing; no problems with connections that are still open/closed/busy. Works quite fast, since connection-objects are returned to the pool.

Create a connection, create a command, execute.

Huh?

anishkannan wrote:

I don't think that every user needs a pool of connections.

Thanks for reply...

Your suggested option is the open statement execution then close;

In Case, the single web request has multiple open and close; it have any problem?

i face this : If access multiple user in many days, some times got exception as maximum pool reached in database side...

Singleton : i mean that, single open at the time of first ; all statement execution then close

Pete O'Hanlon3-Apr-12 2:13

If you're using the ODP.NET libraries, you could be hitting the maximum pool issue because you have unclosed connections - make sure you dispose of your connections as early as possible. Basically, the standard technique is to open the connection as late as possible and dispose of it as early as possible. We had a system with a 1000 users all hitting the Oracle server, and we never needed more than 10 connections in the pool to service them because of this simple mantra.

We are using our own data access layer. which has

<pre lang="c#">
   public DataSet ExecuteProcedure(string strProcedure, Hashtable hashTableParameters, string tableName, ref DataSet datasetToFill)
        {
            try
            {
                Open();//  objConnection = new OracleConnection(strConnection);
                // Procedure Execution 
                // data fill to dataset 
            }
            catch (OracleException ex)
            {
                throw ex;
            }
            catch (Exception e)
            {
                
            }
            finally
            {
                Close(); // objConnection.Close();
            }

            return datasetToFill;
        }

Please tell me. if anything wrong in this ( i need correct in this code if has any mistaken )

we are using oracle sql developer client software. how check the connection pool in oracle db.

Eddy Vluggen3-Apr-12 2:41

using (objConnection = new OracleConnection(strConnection))
{
  // do your stuff here
  using (objCommand = objConnection.CreateCommand())
  {
  }
}
// no need to close or dispose.

Well, I can point out a couple of things here.

anishkannan wrote:

{
throw ex;
}

Completely useless code. Never catch and throw without doing something with it.

anishkannan wrote:

{

}

You're just consuming the exception here. You have no way of knowing what's going wrong in your code now.
