By Mike Prestwood

ASP Classic versus C++: A side by side comparison between ASP Classic and C++.

Statements

Common statements such as if statements, loops, etc.

Exception Trapping

[Other Languages]

Languages Focus

A common usage of exception handling is to obtain and use resources in a "try-it" block, deal with any exceptions in an "exceptions" block, and release the resources in some kind of "final" block which executes whether or not any exceptions are trapped.

ASP Classic: On Error

Syntax Example:

On Error Resume Next
  Response.Write FormatDateTime(f_CurrentActualDate, vbShortDate)

  If ErrNumber <> 0 Then
    Break(f_CurrentActualDate)
  End If
On Error Goto 0

Using On Error Resume Next

C++: try/catch

Syntax Example:

try {

  //Some code.

catch(AnError) {

  //Error code here.

If Statement

[Other Languages]

ASP Classic: If..ElseIf..Else..End If

The End If is optional if you put your code on a single line.

Syntax Example:

//Single line example.

If X = True Then Response.Write "hello"

//Complete example.

If X = True Then
  '>>>do something.

ElseIf Y = "ABC" Then
  '>>>do something.
Else
  '>>>do something.

End If

ASP Classic If Statement (If..ElseIf..Else..End If)

C++: if..else if..else

Same as standard C.

Syntax Example:

//C++Builder example using the VCL ShowMessage.

int x;

x = 8;

if (x == 10) {
  ShowMessage("x is 10.");
} else if (x < 10) {
  ShowMessage("x is less than 10.");
} else {
  ShowMessage("x must be greater than 10.");
}
