Printing Green part of star also prints spaces over red star. Red and Green stars should print at same print, or you had to just move cursor instead printing space. I tried it basicaally worked, but some of code had to rewrite.

String can't be modified in .net. You could use array of byte or array of char. Ascii code could be presented as byte (8 bits). [CODE] byte[] buffer=new byte[4096]; [/CODE] If string length will be short it also quite efficient to use rebuild new string with replace

It's bad behavier to use many incrementation or decrementation with same variable in same statement. C standard does not support this. Result depends on compiler, version and optimations on compiler. Order of incrementations could happpen in any order.

Use abstract class if you want to create new inherited classes. Interfaces are suitable to add abstract methods to existing class hierarchy.

I have used string.Compare or ComporeTo to compare strings. I think that equality function checks only that strings are really same instances. PS string.IsNullOrEmpty(oldpassword.Text) is very useful

You can create normal application and then modify application settings to create library from your project. I just made that with my form designer project.

At least there is bug at begin of buildlist: head is argument of the fuction, but value of it is losed at begin of function. I cant't find any sense about malloc functions. First malloc just produces memory leak and second one just deletes argument. [CODE]# struct list_node* buildlist(struct list_node …

Add eventhander in constructor of child form like this, Eventhandler must be introduced as public. In example I will use form named Main as main form. [CODE] public Form2() { InitializeComponent(); button1.Click+=new EventHandler(((Main)Application.OpenForms["Main"]).button1_Click); } [/CODE]

Try to deactivate controls before making controls invisible. It seems that hiding control that is active may jam sotfware in strange way.
