Why is not an image inserted in the RichTextBox?
1
I tried to insert image into RichTextBox by clicking the button.
I referred this post - How can I insert an image into a RichTextBox? and made the source code
private void button2_Click(object sender, EventArgs e)
{
OpenFileDialog f = new OpenFileDialog();
f.Filter = "BMP (*.bmp)|*.bmp|JPEG (*.jpg, *.jpeg, *.jpe, *.jfif)|*.jpg;*.jpeg;*.jpe;*.jfif|GIF (*.gif)|*.gif|PNG (*.png)|*.png|All files|*.bmp;*.jpg;*.jpeg;*.jpe;*.jfif;*.gif;*.png";
if (f.ShowDialog() == DialogResult.OK)
{
// Get type of the file
string typeOfFile = "";
Stack<char> typeParse = new Stack<char>();
int pointer = f.FileName.Length - 1
while (pointer > 0 && f.FileName[pointer] != '.')
typeParse.Push(f.FileName[pointer--]);
while (typeParse.Count > 0)
typeOfFile += typeParse.Pop();
typeOfFile = typeOfFile.ToLower();
// Convert Image to byte
Image image = Image.FromFile(f.FileName);
MemoryStream ms = new MemoryStream();
image.Save(ms, System.Drawing.Imaging.ImageFormat.Png);
// Insert the image data in RichTextBox which is converted to hex from byte
// by using BitConverter.ToString(ms.ToArray();
StringBuilder imageRTF = new StringBuilder();
imageRTF.Append(@"{pict" + typeOfFile + @"blippicw" + image.Width + @"pich" + image.Height);
imageRTF.Append(@"picwgoal" + image.Width + @"pichgoal" + image.Height);
imageRTF.Append(@" " + BitConverter.ToString(ms.ToArray()) + @"}");
string rtf1 = richTextBox1.Rtf.Trim().TrimEnd('}');
string rtf2 = imageRTF.ToString();
richTextBox1.Rtf = rtf1 + rtf2;
}
}
but when I executed and opened png file, only one line break was inserted in RichTextBox..
What is wrong??

My guess would be this: YourrichTextBox1.Rtfhas the following blankRtfcode -{rtf1}- with the follwing linestring rtf1 = richTextBox1.Rtf.Trim().TrimEnd('}');you are trimming the last}which results in only{rtf1- closing}is missing now you only add your{pict…}which results in{rtf1{pict…}still the closing tag forrtf1is missing

You could also use the ClipBoard to Copy/Paste an Image into the RTB. Maybe you'll find it easier (and you don't really need to know how RTF works).

I modified the code after seeing your comment. I deleted 3 line below the code (string rtf1, rtf2, richTextBox1.Rtf) and addedrichTextBox1.Rtf = richTextBox1.Rtf + imageRTF.ToString();but this still isn't working... did i wrong??

Clipboard is the most commonly used way but beware: It will always be a cludge and a rather volatile one as basically all things one would want are missing, e.g. a frame/textframe you could move around..
