My Little Notebook: Writing a simple content management application

CMS application ေလးတစ္ခုကုိ ေရးၾကည့္တာပါပဲ။ FCK editor ကုိ ေဒါင္းပါမယ္။ ျပီးရင္ FCKeditor.Net: ASP.Net Control to easily integrate FCKeditor on ASP.NET pages ကုိ ထပ္ေဒါင္းပါမယ္။ သူက FCKeditor ကုိ ASP.net မွာ သံုးလုိ႔ရေအာင္ ခ်ိတ္ေပးတဲ့ (.dll) library file ေလးပါ။ ျပီးရင္ project folder ထဲကုိ Content.txt ဖုိင္ေလးမွာ စာေတြ ေရးထားပါမယ္။ (အဲဒီမွာ text ေတြကုိ save ထားဖုိ႔ပါ။ text ဆုိတာမွာ မူရင္း text ေတြေရာ၊ FCKeditor နဲ႔ ျပင္လုိက္တဲ့ text ေတြကုိေရာ အဲဒီမွာပဲ overwrite လုပ္ပါမယ္။ ) ဒုတိယေဒါင္းထားတဲ့ ASP.net အတြက္ editor ကုိ "bin" folder တစ္ခုေဆာက္ျပီး ထည့္ထားေပးပါမယ္။ ေအာက္မွာ ကုတ္ေတြ ေပးထားပါတယ္။
Code for Default.aspx

Code for Edit.aspx

<%@ Page Language="C#" AutoEventWireup="true" CodeFile="Edit.aspx.cs" Inherits="Edit" %>

StreamWriter objstreamwriter;
objstreamwriter = File.CreateText(Outfile);

}

စာကုိ FCKeditor နဲ႔ Edit လုပ္တာ Error တစ္ခုခုတက္လာရင္ ဒီလင့္မွာ ေဖာ္ျပထားပါတယ္။
