Look what you have to do..... go to reference option of your project and uninstall the one which are identical, there may be same reference with different version.

this code show my text like "ﻢﯿﺣﺮﻟا ﻦﻤﺣﺮﻟا ﷲ ﻢﺴﺑ" its wrong because its rtl language the correct way "بسم الله الرحمن الرحيم"

CT.RunDirection = PdfWriter.RUN_DIRECTION_RTL;
Good luck bro

}
}
}
private void Form1_Load(object sender, EventArgs e)

}
In the part:
using (Bitmap bmp = (Bitmap)Clipboard.GetDataObject().GetData(DataFormats.Bitmap))
{
if (bmp != null)
{
bmp.Save(#"d:\files\savedlinks\" + img.nameProp);
pictureBox1.Image = bmp;
}
}
Even if the bmp is not null after one iteration i'm getting exception on the bmp.Save line: Illegal characters in path
And i see in nameProp 395937.thumb?d=1348638415
The other problem is if i'm not using the lines:
bmp.Save(#"d:\files\savedlinks\" + img.nameProp);
pictureBox1.Image = bmp;
If i delete this two lines and using break point on the line:
if (bmp != null)
It will keep stop on this line for ever it will never stop it will keep stop on this line over and over again it will not stop on the foreach but only on this line.
What i want to do is to download from each link the images and also to make it optional to download specific images types like only jpg or only png.
Illegal characters in path error is because your file name is not a valid file name to save because it has invalid character like: '?'
Why the loop is endless, this need more debugging, Debug your code step by step, check the number of images on the first loop,
is it a huge unexpected number of images?
does the number increase on each loop? -> this may be a referencing issue.
i am doing a WPF application to import my image from my folder into excel using c#. I had been successful with using microsoft excel but i would like to know if it is possible to view the file if the user does not have microsoft excel installed? Below is the code which i tried converting the image to a String but it does not display in the excel.

So if the user has Excel the image will show. Make it so that if the image does not show (there is no Excel) the image opens in something else like pain, or whatever program you want the image to be in.
I know how to upload a video to Youtube using Youtube API within C#
But I'd like to use the Youtube API to return a date when a particular user last uploaded a video.

You can get all the user's videos and get the latest date:
var videos = new YouTubeRequest().GetVideoFeed(userId).Entries
DateTime lastUploadDate = videos.Max(video => video.YouTubeEntry.Published)
To get the actual video's title:
var lastVideo = videos.Where(video => video.YouTubeEntry.Published == lastUploadDate).First();
var name = lastVideo.Title
Getting an "Access Violation" runtime error when trying to get a WebBrowser's .Url property in an Outlook Add-In I'm writing. Need some help on how to get past this please. Research indicates I may need to set "FullTrust" permissionset, have tried that with no success.

browser.Url is initially null, Change your code as below.
if (browser.Url != null)
{
currentUrl = browser.Url.ToString();
