It descibes how to use the FB ads api.

The documentation is language-agnostic. If you need a third-party wrapper that talks from C# to FB on your behalf, have a look at the Facebook SDK[^].

What is an image cup and what is an image cover? The question needs a lot more definition.

You already asked this question yesterday in QA.

Asking it again is not going to change the questions, nor the answers you get. You simply haven't provided enough detail about EXACTLY what you are doing and how you are doing it for anyone to help with any accuracy.

As a part of my project i need c# code for compairing two finger print images. I already had some finger prints. so I need help to check whether the two finger prints matching. No need of fingerprint scanner.
please help me..
Thanks in advance.

How to read bytes from Stream into Objects?

Software20072-Jul-12 17:27

I am sending data from mobile app to REST in binary format like this:

"firstname=Mike&lastname=Smith&..binary represenation for the image here.."

class Employee{
string firstname;
string lastname;
Stream photo;
}

public string PostMethod(Stream streamObj)
       {
           using (FileStream filetoUpload = new FileStream(filePath + filename, FileMode.Create))
           {
               byte[] byteArray = new byte[10000];
               int bytesRead = 0;

               do
               {
                   bytesRead = streamObj.Read(byteArray, 0, byteArray.Length);
                   if (bytesRead > 0)
                   {
                       filetoUpload.Write(byteArray, 0, bytesRead);
                   }
               }

               while (bytesRead > 0);
           }

           return "Uploaded " + filePath + filename;
       }

I do know how to get the contents of the Stream into a byte array. What do I need to do to be able to read the bytes from the StreamObj into the class? Some pseudo code would be helpful.
employee.firstname = ...
employee.lastname=...
employee.photo=....

First you need to split your array into sections as delineated by the & character. You can then convert the first two to properly encoded character strings using the System.Text.Encoding.GetChars()[^] method, and then split them based on the = character.

Might not work - I think he needs to look a little more closely at his data. The third section is raw binary by my interpretation, so it probably shouldn't be in a string at all or he runs the risk of unicode conversion problems.

My suggestions were largely guesswork, but I wasn't proposing to convert section 3 to a string, just the first two.

Google for Serialize/deserialize - takes only a few lines of code. You'll be wanting the BinaryFormatter.

OriginalGriff is correct that the image section is raw binary. So, what to do again?

Serialize your employee, using the binaryformatter Smile | :)

Serializing means that you'd encode it in a portable format. You can use different formatters, but the Xml-version doesn't sound too appropriate under these circumstances, hence the binaryformatter.

Can you elaborate a bit. So, I have a stream

"firstname=Mike&lastname=Smith&..binary represenation for the image here.."

in binary format.

[Serializable]
    public class Employee {
Serialize()..
Deserialize()..
}

This sounds like I need a file for the serialization, but I thought this was memory data type of thing.
Anyways, what after this, how do I read it in to the class members what I don't get?
How do I go from Stream type which is sent to me to Employee? Note, stream comes from iphone app.

SpellChecker

Hi,

I have created a Texteditor using C#. In this I am using Spellchecker with the help of NHunspell.

When i am entering more than 60000 characters its hanged. Its performance is too slow. But its very fast while the spellchecker is off.

How can i achieve the spellchecker is on for the customer view page only onto the entire.

The following code that i can used for dictionary on/off

if (btnsCheck.BackColor==Color.Green)
{
this.NHunspellTextBoxExtender1.SetSpellCheckEnabled(this.TextEditor, false);
this.NHunspellTextBoxExtender1.SpellAsYouType = false;
btnsCheck.BackColor = Color.Red;
}
else
{
this.NHunspellTextBoxExtender1.SetSpellCheckEnabled(this.TextEditor, true);

string TempSt = this.TextEditor.SelectedText;
this.NHunspellTextBoxExtender1.SpellAsYouType = true;
this.TextEditor.SelectedText = " quot;;
btnsCheck.BackColor = Color.Green;
}
}

Thanks,
Murugavel S

Have a look at NHunspellTextBoxExtender - A Spellchecking IExtenderProvider for TextBoxes using Hunspell for .NET[^].

Look at the Optimizations section in the article.
Preventing redrawing and scrolling could improve performance too.

Hi Murugavel,

I think you should be using background thread to do spell checks to overcome UI unresponsiveness.
Execute your spellcheck call this.NHunspellTextBoxExtender1.SetSpellCheckEnabled(this.TextEditor, false); in a different thread.

This is one of the uses of the Windows SetWindowPos function and is demonstrated with an annoying program that makes all open Notepad windows topmost for 10 seconds. That's just long enough to click on them a few times to confirm the modified behaviour before they revert to normal.
