Again, we will define a condition and one or more instructions:
| <%
mynumber=0 Do While mynumber<10> response.write("Hello ") mynumber=mynumber+1 Loop
|
In this example the condition is "mynumber<10">
Do Until....Loop
Quite similar to the previous one, it also includes a condition and one or more instructions:
| <%
mynumber=0 Do Until mynumber=10 response.write("Hello ") mynumber=mynumber+1 Loop
|
In this example the condition is "mynumber=10", so mynumber will increased until it is equal to 10, and then the loop will be abandon.
Let's see an example using this Do Until...Loop:
| <%
myfirstnumber=0 mysecondnumber=0 Do Until myfirstnumber=15 Do Until mysecondnumber=15
Loop Response.write ("END")
|
The result of the script is this one:
| XXXXXXXXXXXXXXX
XXXXXXXXXXXXXX XXXXXXXXXXXXX XXXXXXXXXXXX XXXXXXXXXXX XXXXXXXXXX XXXXXXXXX XXXXXXXX XXXXXXX XXXXXX XXXXX XXXX XXX XX X END |
Select Case....End Select
This is a very useful instruction in case we want to check different values for variable. Lets check an example:
| 1
2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 | <%
mynumber=3 Select Case mynumber Case 1 Response.write ("Number 1") Case 2 Response.write ("Number 2") Case 3 Response.write ("Number 3") Case 4 Response.write ("Number 4") Case 5 Response.write ("Number 5") Case Else Response write ("Mynumber is higher than 5") End Select %> |
In this example above, we have defined mynumber as 3, so they are executed the instructions following line 8 (in this case only one instruction is executed, but they may be several instructions). Case Else is not necessary.
Let's try a second example:
| 1
2 3 4 5 6 7 8 9 10 11 12 13 | <%
username=request.form("username") Select Case username Case "Peter" Response.write ("Hello, Peter") Case "John" Response.write ("Hello, John") Case "Joe" Response.write ("Hi, Joe") Case Else Response write ("I do not know you") End Select %> |
Let's see a different example:
| backgroundform.html |
