Can anyone help me to add an image in crystal report? I write in C#. In my access database, I store the path of the image , not the real image. The real image is in another directory. Thank you very much.

I know that if I used PlainText, this problem wouldn't happen. But I have to use UnicodePlainText because my file is Vietnamese, it needs font Unicode.

here is my function to load the file void OpenFile() { openFileDlg.DefaultExt = "*.txt"; openFileDlg.Filter = "Text Files|*.txt"; if(openFileDlg.ShowDialog() == System.Windows.Forms.DialogResult.OK && openFileDlg.FileName.Length > 0) { rtxt.LoadFile(openFileDlg.FileName, RichTextBoxStreamType.UnicodePlainText); } }

I have a problem when using richtextbox. I use richtextbox to display the content of a file. In the richtetxtbox, it automatically inserts a space in the first word. For example, in my file " Doctor John is very kind". And in my richtextbox "D octor John is very kind". Why do I meet this problem and how can I overcome this problem? Thanks a lot.
