      It is not advisable VB.NET Message Box in web applications.

      In web applications there is server-side code that processes requests (This is your VB.NET code) and there is client side code which is run in the web browser (this includes HTML, CSS and JavaScript).

      The server side code generates the client side code, the client-side code operates separately in the browser and then sends requests back to the server.

      The message box control that you are looking to use should be done at a browser level and so it requires client-side functionality.

      The VB.NET "MessageBox " control cannot help you since the VB.NET code is executed on the server.

      You need to include JavaScript in the HTML that the VB.NET code generates to use the JavaScript alert('message' ) functionality to display a message box in the web development world.

          Thanks Frinavale for your reply
          msgbox was not giving error before deployment,it was working well while testing web app using view in browser.
          But now i understood client and server side well
          I replaced message box with below code and it works well for me.
          Code:
          Response.Write("<script type='text/javascript'>alert('---MY message -----');</script>")

              Looks good but be careful about putting that in your server side code.

              When you use Response.Write in your server code sometimes it gets inserted into the generated output outside of the html (like before the <HTML> begin tag).

              It's best to use Response.Write within your ASP code instead.

              Or, if you need to do server operations you could use the Page.REgisterCl ientScriptBlock Method if you aren't using AJAX or the ScriptMnaager class if you are using AJAX.
