Access HTML Editor Example

Tonight I added an improved example of how to create a Heading 1 style and add and remove a color style. This is useful for an Access HTML Editor using the Web Browser Control. Note how one can program DHTML from within an Access .NET Addin.

Source Code: http://desktopweb.codeplex.com/SourceControl/changeset/changes/5386

Apply an H1 element

void Heading1_Click()

{

Tasks.HtmlDocument.execCommand("formatblock", false, "<H1>");

}

Apply a color style

void ColorCombo_Change()

{   

//Apply style

try

{

mshtml.IHTMLTxtRange rng = (mshtml.IHTMLTxtRange)Tasks.HtmlDocument.selection.createRange();

             

string text = rng.text;

       var elem = rng.parentElement();

       if (elem.tagName != "SPAN")

       {

rng.pasteHTML("<span style='color:" + Tasks.ColorCombo.Text + ";'>" + text + "</span>");

              rng.moveStart("character", -text.Length);

              rng.select();

      }else if (elem.tagName == "SPAN" && elem.style.color != string.Empty)

      {

      if (Tasks.ColorCombo.Text != string.Empty)

elem.style.color = Tasks.ColorCombo.Text;

      else{

              //Remove SPAN element

              rng.pasteHTML(text);

              rng.moveStart("character", -text.Length);

              rng.select();

      }

   }

Tasks.WebBrowser.SetFocus();

   }

catch (Exception) { }

}
