I'm trying as best as I can to add a image into a Rich TextBox (ExRich TextBox)

This code
CODE

                rtfChat.InsertImage(new Bitmap(typeof(ResourceManager), "Heart.png"));

Is what's giving me a real headache. Whenever I try to insert the image I get Error: "Can't Find the resource Heart.png In the Class System.Resources.ResourceManager" (roughly translated)

I have tried various typeof classes, but honestly I don't know which one to "select"
I'm stucked to say the least

The entire code is:
CODE

        private void rtfChat_TextChanged(object sender, EventArgs e)
        {
            try
            {
                int _index;
                if ((_index = rtfChat.Find(":)")) > -1) {
                    rtfChat.Select(_index, ":)".Length);
                rtfChat.InsertImage(new Bitmap(typeof(ResourceManager), "Heart.png"));
                }
            }

What I'm actually trying to achieve is that whenever ":)" is active in the Rich Text the text ":)" should be replaced by a Image (not entire text, but only ":)" )

I've spent hours on this so I would really appreciate some help.

Well this is the easiest way I know of for getting an image from a Resource file

CODE

ResourceManager manager = new ResourceManager ("myResources", Assembly.GetExecutingAssembly());
Bitmap bmp = new (Bitmap)manager.GetObject("myImage");
rtfChat.InsertImage((Image)bmp);


Just so you know what to change, here's how I created my resource file and added an image to it

CODE

private void CreateResourceFile()
{
    System.Resources.ResourceWriter writer = new System.Resources.ResourceWriter("myResources.resources");

    writer.AddResource("myImage", new Bitmap("test.jpg"));
    writer.Generate();
}


So then your method would look like this

CODE

private void rtfChat_TextChanged(object sender, EventArgs e)
{
    try
    {
        int _index;
        if ((_index = rtfChat.Find(":)")) > -1)
        {
            rtfChat.Select(_index, ":)".Length);
           Bitmap bmp = new (Bitmap)manager.GetObject("myImage");
           rtfChat.InsertImage((Image)bmp);
        }
    }
    catch (Exception ex)
    {
        //do your error catching here
    }
}


Hope that helps smile.gif
