of course, use .PadLeft(2, '0'); which will add 0's to the start until the length of the string is 2

Yes. From the Assembly object you can use the GetTypes() method which returns an array of Type objects.

Yes, you can use one of the static Load methods on Assembly. If you only want to query the assembly without running code on it you can use one of the ReflectionOnlyLoad methods instead.

(for example)
Type _type = Assembly.GetAssembly(this.GetType()).GetType("class name");

or

Type[] array = Assembly.GetAssembly(this.GetType()).GetTypes();

Hi,

You can just add eventhandler for the button in code-behind file as follows :

button1.Click += new RoutedEventHandler(button1_Click);

Hi,

Just try to put your code in try & catch block. Because you are getting datatype mismatch error. The conflict is between the data you are passing and the data-type of the fields in database.

May be error is due to date field.

There are many ways to acheive this, the easiest is to adjust the constructor for form2 to accept a textbox argument and store that as a variable in the form2 class in the constructor. Then you can access or change any of the form1.textbox properties from form2.
