C# : What is the difference between ref and out?

As far as I understood, the ref is like in/out and out is just out. What I meant is that you can send a value in to a function using a ref parameter but you can't send a value using an out parameter. Out parameter can be used only for returning a value from a function. Also the ref parameters should be initialized before passing to the function.

I had to do a code like the one shown below

txtSample.Text = "Text Sample1";

//few lines of code

txtSample.Text = "Text Sample2";

But it was showing only 'Text Sample2'.

I was looking for a solution and I found that I need to invalidate the rectangle so that the new text will be displayed. There is a method Invalidate() associated with all the controls. But it was not working for me. You need to use the Refresh() method if you need the control fully painted before you take the next step.

Problem after hosting webservice

When I tried to host a WebService and then to check it in the browser I got the content of the file rather than the list of WebMethods.

To solve this, first check whether the asp.net version is set in the website properties in IIS.

If your problem is not solved (most probably you install IIS after installing .net) run "aspnet_regiis.exe -i"(it will be there in your .net frame work folder) and then run "iisreset".

This fixed my problem.
